Causes and solutions of insulating glass failure.

Summary. The main cause of common problems in the glass curtain wall, such as "glass rain", insulating glass failure, lighting roof breakage and falling, one is the design. For example, the main stressed member aluminum profile column is not set up with 20mm expansion joints according to the specification, and the waterproof sealing treatment of the opening window is invalid or the number of sealing layers is insufficient.

The second is aluminum profiles. The oxide film of the surface coating is too thin and too thick, resulting in the failure of the sealant. The third is sealant.

The use of ordinary sealant causes blistering, cracking and non-solidification of the glue joints, resulting in water seepage on the curtain wall. Fourth, glass. The strength of the glass is not enough bearing capacity, and the glass dimensional tolerance exceeds the standard, etc., which will cause the glass to crack or crack darkly, resulting in water seepage.

Fifth, construction. Failure to operate according to specifications during the installation of aluminum frames and sealant construction, or failure to meet quality standards, will also bury hidden dangers for water leakage. Sixth, use.

After some users move in, they do not understand the use of the curtain wall, resulting in damage, collision deformation, pollution, etc., which will lead to water seepage. Some users do not use neutral detergents when cleaning the glass or do not rinse it with clean water after cleaning, which will cause corrosion, damage the sealing performance, and is also one of the causes of water seepage.

The main common problems in the glass curtain wall, such as "glass rain", insulating glass failure, and broken and falling of the lighting roof.

How long is it going to take. The main cause of common problems in the glass curtain wall, such as "glass rain", insulating glass failure, lighting roof breakage and falling, one is the design. For example, the main stressed component aluminum column is not set up with 20mm expansion joints according to the specification, and the waterproof sealing treatment of the opening window is invalid or the number of sealing layers is insufficient.

The second is aluminum profiles. The oxide film of the surface coating is too thin and too thick, resulting in the failure of the sealant. The third is sealant.

The use of ordinary sealant causes blistering, cracking and non-solidification of the glue joints, resulting in water seepage on the curtain wall. Fourth, glass. The strength of the glass is not enough bearing capacity, and the glass dimensional tolerance exceeds the standard, etc., which will cause the glass to crack or crack darkly, resulting in water seepage.

Fifth, construction. Failure to operate in accordance with the specifications when installing the aluminum frame and carrying out sealant construction, or failing to meet the quality standards, will also bury the hidden danger of leakage. Sixth, use.

After some users move in, they do not understand the use of the curtain wall, resulting in damage, collision deformation, pollution, etc., which will lead to water seepage. Some users do not use neutral detergents when cleaning the glass or do not rinse it with clean water after cleaning, which will cause corrosion, damage the sealing performance, and is also one of the causes of water seepage.

Generally speaking, there are many reasons for the glass curtain wall glass breakage, the common ones are glass self-explosion (generally common in summer when the temperature is high), the glass size difference and the aluminum alloy frame ratio is not suitable (the glass size calculation is wrong), the glass is stressed and damaged under the action of displacement, and the glass is not added with a rubber attack cushion block or a hard neoprene cushion block (not allowed to be used) resulting in uneven stress damage to the glass.

The sealant will age, separate from the glass, lose its proper sealing performance, and water vapor will enter the cavity. When winter arrives and temperatures drop below freezing, the surfaces inside the glass cavities fog up, condense and even freeze. This is a problem of physical and chemical properties.

As for dirty and scratched glass surfaces, that's a problem that all glass will have, so don't say much.

(1) Strictly control the temperature of the production environment.

The production environment mainly affects the adhesion capacity and the residual adsorption capacity.

2) Reduce the diffusion of moisture through the polymer.

It mainly depends on the selection of sealants with low permeability coefficient to determine the reasonable sealing thickness and reduce the temperature difference between the inside and outside of the insulating glass (that is, to control the production within a certain temperature range and not to make the temperature range too large).

3) Reduction of production process time.

Minimize the time of contact between the desiccant and the atmosphere, reduce the loss of adsorption capacity and make the desiccant have a higher adsorption capacity.

4) Choose the right aluminum profile.

The air conduction gap of its fine pores should be small to reduce the water absorption rate of the molecular sieve during operation.

5) Choose the right desiccant.

Choose a desiccant with a high adsorption rate and a long-lasting duration.

It is believed that through the control of material selection, processing, environment and other links, the quality of insulating glass will be significantly controlled.

1. In the middle of many insulating glasses is air, which is the air we usually breathe;

2. If you want to fill gas, it is also argon, and I have never seen helium filled, because the cost of helium and argon is different, and the effect to be achieved is the same.

3. I don't know where you heard about helium. If you don't particularly need sound insulation, it is recommended to use ordinary insulating glass, even if you need sound insulation, you can also make double or triple hollow glass, not necessarily filled with argon, because the argon content can not detect his accuracy, and the gas filled with time will soon be diluted, and it will not have a great effect in the long run.

Is there helium in the middle of ordinary insulating glass?

Filling this inert gas is expensive, right? In general, insulating glass has air in the middle.

Is helium better at sound insulation?

This one has not been studied, and it should feel about the same. If you really want to be filled with helium, there should be other special requirements, mainly not for sound insulation.

The sound is transmitted by the vibration of the object, and if you want to know whether the sound insulation effect is better, the sound insulation effect of vacuuming in the middle will be better than the inflation effect. This will be much more expensive.
