Why is there fog in insulating glass, the general shelf life of insulating glass in engineering wind

There are no national regulations, which are generally agreed upon by both the supply and demand sides.

The quality assurance of insulating glass depends on the quality of the glue molecular sieve used in the rest of the plastic, and the inferior glue leaks in less than a year==== Like our company, the warranty of 10 years is written into the contract of the manufacturer, I believe that there are no more than 20 in the country.

The quality of the sealant is not good, or the air in the middle is not removed when it is hollow, and the argon gas in the glass can prevent this.

It was because the glue connecting the glass was not sealed, and there was air intake.

No, there are two types of double-glazed glass in the market: vacuum glass and insulating glass, which are manufactured in different ways. Vacuum glass is a double-layer glass seal, and the gas inside is pumped out.

The insulating glass is only a double-layer glass sealant, and there is still a lot of air in it, which is dried with molecular sieve desiccant to continuously adsorb the moisture entering the spacer layer during the life of the insulating glass. When insulating glass encounters cold weather, the indoor and outdoor temperature difference is very large, it is easy to fog and small water droplets, and it will slowly disappear after being exposed to the sun.

Solutions for fogging of double-glazed windows:

If the phenomenon of fogging of the double-layer glass caused by the sealant is not tightly sealed, the sealant on the double-layer glass can be removed with a tool, and the glass window can be cleaned again, and the glass window sealant can be painted after it is dried;

If the sink of the double-glazed window is not properly installed, the double-glazed window should be removed and reinstalled;

If the dividers in the double-glazed windows are properly installed, a glass gasket can be added to the double-glazed windows. Remove the original spacer on it, and then reinstall the spacer, pay attention to the pasting position of the spacer to maintain a certain distance from the edge of the glass window, generally 2mm is more suitable. And when installing glass windows, be careful not to get water on the middle septum, so as not to affect its performance;

If the fogging phenomenon is caused by a large temperature difference, you can open the window for a while to make the temperature difference between indoor and outdoor smaller, and wait until the fog on the surface dissipates.

There is an air leak, or the desiccant is too little to fail. It's hopeless, and the glass has to be replaced. Or the glass is dismantled, re-cleaned, and then re-filled with desiccant, and re-glued.

If you don't have a lot of square meters, it's good to reorder it directly, pay attention to the specifications of the glass: 1, width and height 2, the thickness of the glass (the thickness of the original glass sheet and the thickness of the aluminum spacer in the middle.

The basic production process of double-layer insulating glass for home doors and windows is composed of glass cleaning, molecular sieve filling, butyl sealant coating, lamination, and second sealant. Each step is closely related to the selection of materials, the proficiency of the operators and the quality of the processing.

Treatment: Glass cleaning.

Cleaning glass is the first link in the production of insulating glass, and it is also one of the most important links to ensure the tightness of insulating glass. If the oil stains and sweat on the glass cannot be thoroughly cleaned, the adhesive adhesion of the sealant to the glass will be greatly weakened, thus reducing the sealing effect of the insulating glass.

In today's production, many manufacturers, especially small manufacturers, often do not pay enough attention to cleaning glass, resulting in a large number of substandard products entering the market.

Desiccant selection: The properties of the desiccant must be considered when selecting a desiccant. The choice of desiccant is directly related to the type of insulating glass adhesive used, which must be considered in combination.

The choice of dense adhesive strips.

The edge sealing failure of the insulating glass means that the doors and windows lose their due function, not only the energy-saving performance of the doors and windows does not meet the requirements, but also the consumers cannot see the outside through the fogged air layer, which affects the transparency of the insulating glass and reduces the thermal insulation effect. Long-term fogging will cause mildew or alkali accumulation on the inner surface of the glass, resulting in white spots, which will seriously affect the appearance quality of insulating glass. It can be seen that choosing a high-quality insulating glass sealant is the key to preventing fogging of insulating glass.

The selected insulating glass sealant should meet the requirements of national or industry standards, and the first and second sealants of double-layer insulating glass should be suitable and should not be miscible or react with each other, otherwise it may lead to glass surface contamination and even aging.

The choice of hollow aluminum strips.

The lamination is the middle link in the production of double-layer insulating glass. The coating of butyl glue before lamination determines the comprehensive quality of insulating glass. If there is a gap between the two sealants, it will cause an air leak.

It is also very important to choose hollow aluminum strips, and there should be no gaps when sealing.

Care should also be taken to apply a second sealant that is too thin. After installation and use for a period of time, due to the action of ambient temperature changes, sun exposure and wind pressure, the sealant will form cracks, even if it is a very small crack, water vapor may slowly enter the adhesive layer, forming fogging, so that the sealant loses its sealing effect.

Summary. Hello dear, insulating glass fogging is a quality problem, insulating glass is a ten-year warranty. It shouldn't fog up and condense for decades.

It is not recommended to use hot melt adhesive bonded insulating glass, and double-channel closed insulating glass made of butyl glue and two-component silicone glue. The glass butyl glue is not well laid, and the sealant is uneven, resulting in air leakage, which can only be a product produced by a small workshop or a small glass factory, without corresponding equipment.

Are there any regulations and standards for quality assurance of insulating glass inlet fogging?

Hello dear, there is no official one, but each manufacturer has its own after-sales service.

Various manufacturers are also OK, at least for a reference.

The shelf life of this insulating glass is generally ten years.

What is the basis for the 10-year warranty?

It's just some data from the manufacturer.

Then you can provide me with a <>

Whether it's a year or a decade, there must be a basis!

Well, what brand are you, dear.

Hello, pro this is not a brand.

Nowadays, when many homes are decorating, in order to play a sound insulation effect, soundproof glass will be installed, of which soundproof glass mainly has insulating glass, and some are vacuum glass. Many people will choose insulating glass to install in their homes, in fact, the sound insulation effect of insulating glass is also good. If the insulating glass is well sealed, it can also play an anti-fog effect.

But if the insulating glass is not tightly sealed, it will fog up. So the insulating glass we buy, it can keep it for several years without fogging? What if it fogs up?

Today, I will tell you some common sense of insulating glass.

1. The insulating glass will not fog for several years.

1. If the insulating glass material you choose is better, and the sealing performance is also good, then it is difficult for air or rain to enter. In the production of insulating glass, some glass glue will be squeezed into the frame, which can prevent the insulating glass from being unsealed and reduce some problems of glass fogging and moisture.

2. If the sealing measures are done well, it will take about three to five years, and there will be no fogging sail loss.

3. After a long period of use, the glass glue will have the problem of aging, and the sealing performance will be greatly weakened over time, coupled with the invasion of dust, the sealing performance of the insulating glass will be greatly reduced, and the problem of fogging will occur after a few years.

Second, what to do if the insulating glass is fogged.

1. It is difficult to really achieve the sealing effect of this kind of glass when it is made, so fogging is inevitable, mainly because the moisture in the air has a liquefaction reaction, which will form fog on the glass. We can reseal the insulating glass to prevent moisture from entering and solve the problem of fogging.

2. Some glass gaskets can be added to the insulating glass to improve its sealing performance. If the temperature difference is relatively large, the phenomenon of fogging will be effectively reduced.

3. You can also paste a layer of anti-fog film on the insulating glass, so that water mist is not easy to appear on the mirror.

The above points are about how insulating glass can be kept for several years without fogging, and how can we solve the problem of fogging in case of fogging? If you want to know more information, you can also pay attention to the official website of Qijia.

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.
