How you can choose office glass partition

Now the partition technology is often used in the design, especially in the decoration design of the office. The use with the partition can not only make the place get the most perfect application, but also strengthen the cleanliness from the office area and conserve the company’s expenses. So secure choose an office partition?
When buying a partition, you should first be aware of the quality of the actual partition, such as the surface treatment of the material, the built-in keel mode, etc. If it is constructed of Laminated Glass online, it depends upon whether the glass will be tempered or not. The glass that may be not tempered is really dangerous. Some office partitions now use materials just like wall coverings to achieve sound absorption, color plus material aesthetics. In a compact group, the height with the table and the table is often set at about 890 mm, which guarantees a specific privacy of the own space. The work at the desk is not interfered simply by external things, and the surrounding environment sometimes appears while sitting. The layout is convenient for function and communication.
Intersect area cleaning ability and assistance life
When selecting the partition, consider the cleaning ability and service life on the room to be partitioned, and select different materials in line with the situation. There a wide range of different styles of dividers. Try to avoid that monotony of partitions. Once the restaurant is decorated, it may be used in different dividers to reflect the beauty on the whole. It can also be employed to match the color having reasonable results. In add-on, there should be no irritating smell following your partition construction. It is good to select the right one, not really the expensive one, and any material used for decoration is much like this.
The partition produces great convenience to people’s life and work. It is more flexible in the usage of space. The finished product partition might be reassembled and reinstalled. It is usually adjusted according to different needs, making the breathing space design change wider. As a result, it has become essential for the renovation involving corporate office areas. If choosing office partitions, we ought to use our own breathing space arrangement and combine the actual characteristics of partitions for making reasonable use of place.

Basic classification of ultra-clear glass

 

1. Solar ultra-white rolled glass

The solar ultra-white rolled glass component can absorb the radiant heat of solar energy to the maximum extent and maximize the photoelectric conversion efficiency of the solar cell.

The glass can also resist the radiation of the sun ultraviolet light, and the light transmittance does not decrease, so that the service life of the cover glass can be more effectively extended, and the alkali resistance, the anti-fungal ability and the anti-aging property in various environments are better than the ordinary flat plate. The ultra-white glass reinforcement makes the solar cell module cover glass more favorable for protecting the underlying silicon crystal plate from external damage by its own strength and being durable.

2, ultra-white transparent flat glass

Ultra-clear transparent flat glass (commonly known as “crystal glass”) is a new type of transparent flat glass product developed and manufactured. It is a high-tech method that will effectively reduce iron oxide during the optimization and processing of raw materials. A flat glass with a very low iron compound content produced by the melting and forming process of flat glass.

The ultra-clear transparent flat glass has similar appearance characteristics to the colorless crystal. It has no green-like visual effect like ordinary flat glass, and it has higher visible light transmission than ordinary transparent flat glass, from the front or from the side. Rate and transparency.
The development prospect of ultra-white glass

Due to its high technology content and high production difficulty, ultra-white glass is expensive, which is 5 to 10 times that of ordinary glass, but the cost is only 2-3 times that of ordinary glass, and it has a high added value.

Ultra-white glass accounts for 20%-30% of the total cost of thin film batteries.

From the perspective of sales around the world, ultra-white glass is only used in high-end restaurants, urban landmarks, government financial projects, large-scale high-end exhibition venues, such as Beijing’s Bird’s Nest, Water Cube, Chinese History Museum, and the country. The famous theaters of the Grand Theatre, Shanghai Opera House, etc. all use ultra-white glass.

Realizing “glass structure” housing with earthquake-resistant and fire-resistant glass


If the planned personal residence “Glass House” in Osaka City is completed, it will become the first case in Japan where all the main building materials of the building use glass.

The two cuboids of the 4th and 2nd layers are respectively carried on the glass-covered hall. Although the upper part of the living room is of the S structure, the steel hall is not used in the foyer on the first floor. This part uses a structure that is only supported by glass wall columns.

The owner’s request for the designer’s fullness is “to build an unprecedented new building”. “We submitted several design proposals to the owners, and the client selected the most difficult one. The owner’s determination was repeatedly confirmed when taking over the project. Because of all aspects of the building design, it’s troublesome if you don’t do it in the middle.”

Since the owner’s idea has been fixed, we found Arup (Japan) Engineering Consulting Co., Ltd. and Japan Plate Glass Glass Co., Ltd. to start the structural discussion. After repeated trials, the construction plan is getting better and better. Mainly solved two major problems. One is the strength of the glass, and the other is the fire problem. After solving these two problems, the Laminated insulated glass wall column was decided to adopt the following structure:

First, an earthquake-proof layer is placed under the ground floor (reinforced concrete) on the first floor to reduce the horizontal force during the earthquake. The wall columns standing on the ground surface are supported by two sets of double-layer composite glass (four layers in total), and the outer side is covered with fire-resistant glass. Fire-resistant glass only acts as a “refractory cover” and does not bear weight. In order to share the load, the glass wall column and the surface and the wall column and the upper steel structure are filled with filler material.

The double glazing, which was originally considered as a structure, was made of tempered glass, but was finally changed to float glass in order to reduce the cost and avoid the risk of natural breakage. The representative of Arup Japan’s Hikone Mau said: “There is enough margin for strength, and if one of the layers is broken, there are three other supporting buildings.”

Low-E low-emission glass is energy-saving, environmentally friendly, and has broad market prospects.


With the continuous improvement of people’s living standards and the continuous development of social economy, people’s requirements for their own lives and workplaces are getting higher and higher. Glass doors and windows are the main way to communicate inside and outside the building. Lighting, viewing and decoration are the basic requirements for glass. Energy conservation and environmental protection are further requirements for glass doors and windows, and are increasingly valued by the society.

Low-E low-emission glass, which can be processed off-line, not only inherits all the advantages of offline Low-E, but also has a qualitative breakthrough in the traditional disadvantages, effectively solving the problem of many small and medium-sized processing manufacturers. It is said that the combination of offline and online advantages, in the use of Low-E glass products today, will have a broader market prospects.

The development time of low-emissivity glass in China is relatively short, and the brand image of industry enterprises is quite different from that of foreign companies. China’s low-emissivity glass production has reached the world’s advanced level. However, because the brand image and popularity are not as good as those of foreign manufacturers, the price is far from the imported products. The wholesale low-e glass equipment produced in China has superior performance, and the equipment has reached the international advanced level. The price is only about 1/2 of that of foreign similar imported products, which has strong substitution and competitiveness.

Faced with the unfavorable situation of continuous macroeconomic regulation and control, rapid rise in oil prices and prices, severe environmental protection tasks, and rising production cost rigidity, energy conservation and green development have become the development direction of the glass industry. This demand has also accelerated the research and development drive of China’s glass enterprises. Recently, it has been reported that Shenzhen has asked developers to replace all architectural glass with energy-saving glass. From 2012, energy-saving glass must be used along the street surface of new buildings.

How to distinguish true and false hollow glass doors and windows


Regular hollow glass doors and windows are to seal two pieces of glass with a sealing strip, then vacuum the middle and fill with inert gas. Such a structure makes the true insulating glass door and window have good sound insulation performance. However, many inexpensive and inferior insulating glass doors and windows are only glued together with two simple glass pieces, and have not been treated as described above, so there is no such sound insulation effect that is unique to insulating glass.
The first is to see if the glass is sealed. Many fake glass doors and windows are bonded with black PVC foam strips and have no sealing effect. And the real tempered insulated glass doors and windows are bonded with glass with special sealing strips to ensure absolute sealing. There is an aluminum spacer between the two pieces of glass, and there are many venting holes on the aluminum spacer. The desiccant is placed inside, which can absorb some moisture in the gas to prevent fogging after the glass door and window are heated. The phenomenon, and there is no such equipment in the fake insulating glass.
The quality of the profile is distinguished. The high-quality insulating glass doors and windows use high-quality profiles, such as the well-known conch profiles and green profiles in China, while the inferior hollow glass doors and windows use low-grade profiles, which are secondary recycling profiles. The high-quality profiles look smooth, smooth, uniform, uniform in color, free from cracks and air bubbles, and there is no breakage in the weld. The hardness is sufficient. The surface of the profile is not broken by the hammer. Inferior profiles are not uniform in color, and there are bubbles and impurities. When they are hit with a hammer, they will rupture, and even if they are pinched by hand, they will be deformed.

Why does the insulating glass lose its effect? Why is it invalid?


1. The main reason for the rise in dew point

The dew point of the insulating glass refers to the temperature at which the humidity of the air sealed in the air layer reaches a state of saturation. Below this temperature, the water vapor in the air layer condenses into liquid or solid water. The correspondence between the dew point and the relative humidity of the air and the water content in the air.
Obviously, the higher the water content, the higher the dew point temperature of the air. When the inner surface temperature of the glass is lower than the dew point of the air in the air layer, the water in the air will condense or frost on the inner surface of the glass (the dew point of the national standard GB11944-89 “Insulated Glass” is a 40 ° C). The rise in dew point of the hollow glass is caused by the outside water entering the air layer and not being absorbed by the desiccant. The following three reasons can cause the dew point of the
insulated glass factory to rise:

(1) The mechanical impurities present in the sealant or the capillary pores which are discontinuously squeezed during the rubber coating process, and the water in the air flows or diffuses through the gas under the action of the pressure difference or the concentration gradient inside and outside the air layer. Entry into the air layer increases the moisture content of the hollow glass air layer.

(2) The water vapor diffuses into the air layer through the polymer (the sealant is generally a high molecular polymer). Any polymer is not absolutely gas impermeable, as is the case with the sealant polysulfide rubber, silicone rubber, butyl rubber, etc., which are commonly used for insulating glass. The presence of these polymer materials, their two distortions in the difference in the degree of susceptibility (pressure difference or concentration difference) constitutes the driving force for the isothermal diffusion of the polymer. In a higher degree of fugacity, the aggregated g/J molecule moves into the ring polymer due to adsorbed gas molecules (air and water) and passes through the polymer chain from the other side of the polymer – the lower fugacity The side is released. For the sealant of insulating glass, the main diffuser is the moisture in the air.

The diffusion of water follows the following relationship:

J=P/LP(1)

Where: J-diffusion speed. Refers to the amount of diffusion of a certain amount of polymer per unit area per unit area. P-gas permeability coefficient. It is a physical property of materials. The thickness of the L-polymer. The partial pressure difference of the gas on both sides of the P-polymer.

It can be seen from the above formula that the factors affecting the diffusion of water vapor are mainly the gas permeability coefficient (air tightness) of the polymer: the thickness of the rubber layer and the partial pressure difference of water vapor inside and outside the air layer. Water vapor diffusion is the main cause of failure of insulating glass.

(3) The effective adsorption capacity of the desiccant is low. The effective adsorption capacity of the hollow glass desiccant refers to the adsorption capacity of the desiccant after it is sealed to the air layer. It is a function of the performance of the molecular sieve, the humidity of the air, the amount of loading, and the time it takes to place in the air. The desiccant sealed in the hollow glass air layer mainly has two functions – it is to absorb the water sealed in the air during production – so that the insulating glass has a qualified initial dew point: the second is continuous adsorption from the environment. The desiccant is required to have a strong adsorption capacity by diffusing the moisture in the layer to the air in the layer of the air and keeping the insulating glass consistent with the dew point required for use. If the adsorption capacity of the desiccant is poor, the water that diffuses into the air layer cannot be effectively adsorbed, which causes the water to accumulate in the air, the water pressure rises, and the dew point of the insulating glass rises.

2, the reason for the glass burst

There are many reasons for the bursting of the insulating glass. There are production aspects, as well as installation aspects. The main reasons for glass bursting can be summarized as follows:

(1) Production ambient temperature When the insulating glass is produced, the pressure sealed in the air layer is the pressure at the production environment temperature. During use, it is often the case that the temperature of use and the temperature of the production environment differ greatly. The thermal expansion and contraction of air changes the pressure of the air layer. In summer, the ambient temperature is generally higher than the production environment temperature, the air in the hollow glass air layer expands, and the air layer produces a positive pressure, especially with heat absorbing glass and coating. Insulating glass made of glass has a very strong heat absorption effect. The higher the temperature rise in the air layer, the greater the positive pressure produced. When the pressure due to the expansion of the air layer air is higher than the breaking pressure of the glass, the glass may be broken. Most of the glass bursts are caused by this cause. Also in the winter, the ambient temperature is low, and the air in the air layer shrinks to generate a negative pressure. Under the combined action of wind and snow loads, the glass will also burst.

(2) Choosing improper glass. The use of unreinforced heat-absorbing glass on the sunny side of the building, and the use of heat-absorbing glass in the sun-facing surface, it is easy to absorb solar energy and heat up.

(3) The glass is deformed during production. When producing hollow glass by the horizontal method (currently, almost all of the manual production is horizontal), because the area under which the lower glass is supported is small and the support points are mostly at the center, and the weight of the upper glass is all added to the lower glass. The sheet glass is bent upward, resulting in a thinning of the air layer thickness of the insulating glass. When the glass is installed and used, there is naturally a negative pressure in the air layer, and the phenomenon that the glass has a large pre-stressed insulating glass is more prominent. The presence of pre-stress on the glass reduces its resistance to wind pressure and its ability to withstand external forces. It is prone to cracking when external factors change.

(4) Prestressing occurs on the glass when the glass is installed. When the glass is installed, the frame is not flat or the quality of the elastic sealing strip is poor, so that the glass is bent and deformed, so that the pre-stress of the glass and the presence of the pre-stress of the glass reduce the wind pressure resistance of the glass and even burst.

(5) There is a small crack in the edge of the glass. In the production, the quality of the glass edging is not good or the edge of the glass during transportation is not easily found due to collision due to small cracks due to collision (due to the peripheral coating).

Why use insulated glass for broken aluminum doors and windows?

The hollow glass planning of the broken aluminum doors and windows can improve the comfort of the home environment. And it can improve the insulation function of the house, which can effectively hinder the loss of power. Therefore, its application in the market is relatively large.
As a building material, insulating glass is made of two or more pieces of glass. It uses a versatile composite adhesive to bond the aluminum alloy profile containing the desiccant and the glass sheet together, and inject inert gas into the center layer. Glassware. It is part of the planning of the aluminum door and window structure of the broken bridge.
The raw material commonly used for insulating glass is tempered glass. After ordinary glass is cooled by high temperature processing, the hardness is doubled, and the product is tempered glass. Because the hardness of the tempered glass is extremely difficult to be damaged; and after breaking, it is in the form of particles, which is not easy to injure people. So it is also called safety glass.
Advantages of insulated glass factory
Excellent insulation
The insulating glass has a certain vacuum effect due to the filling of the inert gas between the glass, so the thermal insulation function of the broken aluminum door and window is very good.
Useful soundproofing
Insulating glass can make the noise outside the house weakened to a certain extent, and the general noise is transmitted to the room, and people will not feel sad.
Glass is not easy to blew
The manufacturing process of the insulating glass has a bonding method and a cold working process, and an elastic sealing material is used in the periphery, and the internal stress of the glass original sheet is constant, and the glass is difficult to self-explosion.
Anti-fog
There is a drenching agent that absorbs water vapor between the glass to ensure that the hollow glass continues to be boring. Even if the temperature difference in the chamber is large, the aluminum door and window of the broken bridge are not easy to fog.
In the central air layer of the insulating glass, the decorative strips can be embedded to form an assortment of pictures. The use of hollow glass to plan the broken aluminum doors and windows will add a bright color to the home style, and the matching aluminum doors and windows will also play its own role. The choice of broken aluminum doors and windows can take into account the ear.

How to effectively improve the quality of glass clarification


Improving the clarification quality of glass is always the eternal theme of glass manufacturing technology. The factors affecting the quality of glass clarification are multifaceted, physical, chemical, and physicochemical, and there is a complex internal relationship between the three, so that solving the clarification problem can not be too simplistic.

In order to ensure the quality of the glass liquid, reduce and avoid the quality accidents in the production, the company should gradually establish a practical and relatively standardized production operation management system, optimize the production process elements, in order to produce high quality,louver glass price products.

This paper systematically reviews the source of gas in the bubble, the mechanism of bubble generation and disappearance, and the relationship between the glass bubble and the production factors of the raw material and the kiln, in order to eliminate the glass bubbles and improve the clarification quality to find a feasible clue.

1. Mechanism of glass bubble generation and disappearance

To study glass bubbles, first analyze the source of gas in the bubble, the interaction between the gas and the glass, and the effect of the physical and chemical properties of the glass on the process of bubble generation or disappearance.

The gas in the glass bubble usually comes from the following aspects:

(1) Gas in the gap between the raw material particles and gas adsorbed on the surface of the raw material

In the initial stage of compounding, such gas will continuously volatilize or evaporate, and large bubbles will float up during the ascending process to escape the glass liquid, which generally does not directly cause visible bubbles in the glass product. Unless the particle size of the raw material is improperly controlled, the batch of the batch is not sufficiently melted and the gas cannot be discharged.

(2) Gases liberated by salt

There are a large amount of carbonates, sulfates and nitrates in the batch. These salts are decomposed by heat and produce a large number of tiny bubbles. The amount of gas generated by the decomposition of salts is about 15-20% of the weight of the batch. Compared with the formed glass liquid, the volume is many times larger, and the large release and continuous movement of these gases promotes the heat exchange efficiency, accelerates the melting of the batch material, and improves the uniformity of the glass composition and the uniformity of the temperature. However, the bubbles formed by such gases are not eliminated in time to form glass bubbles.

(3) Gas generated by external factors

Gases generated by refractory materials, harmful impurities and gases generated by the action of glass liquid, glass bubbles formed by these gases disappear in normal production for a long time, and it is difficult to disappear, but this situation is relatively rare.

The glass liquid is cooled too fast or the temperature fluctuates greatly, or for various reasons, the redox state of the glass fluctuates greatly. These factors act together to cause the solubility of various gases in the glass to fluctuate, releasing a large amount of tiny Secondary bubble. Such bubbles are characterized by a small diameter and a large number.

Sometimes due to the calculation of the material side or the feeding error during the execution of the material, the glass composition in the kiln greatly fluctuates, and the solubility of the gas in the glass fluctuates, resulting in a large amount of glass bubbles.

There are two ways to finally disappear the glass bubbles in the clarification process: one is that the small bubbles continue to grow into large bubbles, and the bubbles continue to rise due to the difference in density, eventually disappearing from the glass. The other is microbubbles. As the temperature decreases, the solubility of the gas in the glass increases. Due to the surface tension, there are several components of the gas in the bubble. Due to the small diameter of the bubble and the high pressure, the gas is quickly absorbed by the glass. As the diameter becomes smaller, the bubble pressure is continuously increased, and finally the gas in the bubble is completely dissolved in the glass liquid. The small bubbles disappear completely.

2, the elements of the glass bubble

2.1, temperature

The temperature of the glass directly affects the viscosity of the glass, the surface tension, and the solubility of the gas in the glass.

In the glass melting furnace, the glass clarification process is carried out in a high temperature hot spot region, and large bubbles continue to grow and float upward, and small bubbles are continuously reduced and absorbed by the glass liquid. There are many control methods for glass hotspots, and a longitudinal temperature distribution curve is formed in the longitudinal direction of the melting furnace to form two large circulating convections, the melting rate, the fluctuation of the discharge amount, the distribution of the fuel and the structure of the burning flame, and the glass. Factors such as redox state can significantly affect the temperature of the hot spot and the stability of the temperature. In addition, the use of bubbling technology or electric fluxing technology can significantly improve the hot spot of the glass and promote the clarification of the molten glass.

2.2, time

The process of the large floating up and disappearing of the large bubbles in the glass and the absorption of the small bubbles by the molten glass must be completed within a specific temperature range and a specific time range.

Some factors in the melting process, such as the depth of the molten glass, the temperature of the glass at the bottom of the pool, the melting rate, the convection of the glass, the redox state of the glass, the electric flux at the bottom of the pool or the bubbling at the bottom of the pool can obviously affect The disappearance of glass bubbles. If the bubble disappears for a short time, it will eventually remain in the glass to form a glass bubble.

2.3, redox state of glass

The choice of clarifying agent has a great influence on the redox state of the glass, and the clarifying agent promotes the disappearance of the glass bubbles above 1300 °C.

In recent years, with the enhancement of people’s awareness of environmental protection and the improvement of the grade of glass products, many complex clarifiers have been developed. Due to different functions and prices, enterprises have diversified choices of clarifying agents.

The daily detection and control of the COD value of the glass batch material, the stability control of the valence state of the valence metal in the glass liquid, affects the temperature of the bottom of the pool and the redox state of the glass, and finally affects the solubility of the gas in the glass.

3. Control of raw material quality

Strengthening the daily detection and management of batch ingredients, moisture, COD value and batch uniformity is one of the effective ways to stabilize the quality of glass clarification. Once there is a problem in production, this work can find clues to problems in time.

Strengthening the daily inspection and data processing of glass density is one of the important links in the production process control. There is a lot of technical information hidden in the glass density data. According to the statistical analysis of the production of glass density, the density of glass is not only related to the glass composition, but also related to the thermal history of the glass. The structure of the furnace, the scale of production, the size of the melting rate and other factors all affect the thermal history of the glass product. In addition, the type and amount of clarifying agent are different and can be reflected in the glass density data. Some people have done statistical analysis of production. Under the same production process conditions, the use of bubbling and not using bubbling can reflect the density value of glass. It can be seen that the statistical analysis results of the glass density data can directly guide the adjustment of the production process parameters.

If the compound contains sulfate, the change of iron content and valence state in the glass can directly affect the solubility of SO3 in the glass. Therefore, the daily detection and control of the iron oxide and iron valence state in the glass, and the clarification quality of the stabilized glass are Significant positive effect.

Strengthen the control of raw material particle size. In addition to the raw material composition, crystal phase structure, moisture and impurity content control, the average diameter of the raw material particles and the uniformity of the particle-level matching batch, the melting speed and the clarification speed have a direct influence. Excessive raw materials are not conducive to melting and mixing homogenization, but too fine raw materials will increase the cost of raw materials, and will also cause the agglomeration of raw materials, affecting the melting and clarification. In addition, the volatilization and adhesion of the powder will directly lead to the glass components. Fluctuations and changes in compositional uniformity.

Strengthen the control of the redox state of the raw materials. The glass raw materials mainly use mineral raw materials, and a small amount of chemical raw materials contain some impurity components, which have a direct influence on the redox state of the glass liquid, the glass color, the bottom temperature, the melting speed and the clarification speed. At present, some companies have begun to face up to this problem, testing and controlling the raw material COD value of various raw materials, and controlling the COD value and the clarification quality of the glass liquid.

For certain glass products, due to the different scale of production, kiln structure, and melting process, the volatilization of the compound during the melting process, as well as the valence of the oxide, will change the control requirements of the raw materials.

The effect of the redox state of the glass on the temperature at the bottom of the cell and the solubility of the gas in the glass, all of which ultimately affect the clarifying quality of the glass. Therefore, some companies have begun to pay attention to strengthening the control and management of the content of valence oxides and the change of valence state in glass.

4. Control of melting process parameters of kiln

Strengthen the control of hot spots. To strengthen the vertical glass liquid circulation convection, the following process measures are usually taken: one is to control the fuel distribution and combustion process in the furnace, control the longitudinal temperature gradient of the furnace, and promote the circulation convection. The second is to ensure that the glass has a certain depth to form a stable circulating convection. The third is to increase the discharge amount under the condition that the melting area is constant. The fourth is to use bubbling or electric fluxing at the hot spot to highlight the temperature at the hot spot. The longitudinal convection of the glass liquid promotes the homogenization of the glass composition and temperature, improves the heat exchange efficiency, and lowers the temperature of the flame space. Save fuel consumption.

Strengthen the rational distribution management of fuel in the kiln and control of the combustion process. The distribution of fuel in the kiln and the combustion conditions affect the temperature and temperature distribution within the kiln. If the fuel is not burned sufficiently, the reducing carbon black will be absorbed by the glass to form a large amount of microbubbles or brown stripes. Since the structure of the furnace and the structure of the combustion flame are different, even if the glass of the same composition, the volatilization loss of the oxide in the batch material is different.

Bottom bubbling of the kiln plays a special role in the melting process. Bubbling points are distributed in different locations and play different roles. The bubbling point is distributed at the hot spot and can play a special hot spot. Evenly distributed between the feeding port and the hot spot can improve the temperature and homogenization of the glass liquid at the bottom of the pool, and promote the melting of the batch material and the clarification process of the glass liquid. In the bubbling mode, there are two types of continuous bubbling and pulse bubbling. Obviously, the adjustment effect of the latter is more reasonable, and the bubble frequency can be controlled at 5 to 10 per minute. The bubbling material can be made of an expensive platinum-rhodium alloy or a ceramic material resistant to high temperatures and corrosion.

In addition to raw material factors, the uniformity of glass composition and temperature and the design of the furnace structure, the distribution of fuel in the furnace and the conditions of combustion, the structure and length of the material channel, and the level of management of the melting process are inseparable. These factors are ultimately reflected in product quality, cost, and forming efficiency.

5. Improvement of kiln structure design

As we all know, the structural design of glass melting furnace has great influence on heat exchange efficiency, energy consumption and glass liquid quality. Due to different design schemes, energy consumption can be different by 30%. The improvement of heat exchange efficiency not only reduces energy consumption, but also saves production costs, and also promotes the formation of reasonable circulating convection of the molten glass and improves the clarification quality of the molten glass.

In recent years, people have a deeper understanding and understanding of the glass melting process, and environmental awareness is constantly increasing. Countries around the world have strengthened environmental protection legislation to limit the emissions of dust, NO-SO: and F: in glass furnace flue gas. In order to meet these environmental standards, some companies use flue gas treatment methods for traditional kiln to reduce the concentration of dust and harmful components and meet environmental emission standards. Some companies use new technology, such as improving glass formulation and glass composition, limiting sulfur content in fuels, using low NOx combustion technology, using pure oxygen combustion technology, using full fused technology or electric fluxing technology, etc. Advanced technology has promoted the improvement of glass technology to a certain extent.

In recent years, a new type of pool furnace structure has emerged abroad, separating the melting process from the clarification process. The batch material is melted into the cold-top all-electric bath furnace, and the batch material is melted into glass and then enters the flame melting furnace for high temperature. Clarification of homogenization, combining the advantages of an all-electric melting furnace and a flame kiln. This type of kiln prevents the batch from coming into contact with the flame, reduces dust and volatile components, reduces blockage of the lattice, and minimizes the interaction between the melting process and the clarification process.

Glass fiber kiln, advanced pool bottom electric fluxing technology and application of various bottom bubble technology, advanced combustion technology application, boron-free fluorine-free glass formulation, these technologies are directly or indirectly improved The stability and uniformity of the composition of the glass liquid promotes the improvement of the liquid liquid w+.

The uniformity of the temperature of the glass liquid is inseparable from the structural design of the channel and the temperature adjustment method. In order to uniformly reduce the clarified glass liquid to the required forming L: art temperature, the upper space is adjusted by gas premixed combustion to achieve the optimum temperature uniformity of the glass, and the K degree of the material is usually above s meters. . At present, many glass fiber channels, glass wool channels, glass pipe channels, and some glass products are used in this temperature regulation.

In summary, there are many ways to improve the quality of glass clarification. The quality control of raw materials and batch materials, the control of furnace melting process parameters, the improvement of kiln structure design and the design improvement of combustion system, strengthen the exploration and summary of these aspects, and promote the reduction of glass manufacturing cost and product quality.

Office glass partition installation precautions
1. When installing the office glass partition, it should be noted that the upper and lower door shafts must be kept on a vertical line. The skeleton of the glass door must be made of steel beams, and the upper shaft must be welded to the beam because the upper door shaft is the whole The support point of the glass door must be firm. It is forbidden to use the upper beam to adopt the fine wooden keel structure, because the connection point between the upper door shaft and the wood making structure can only be fixed by using the self-tapping screws.
