How to distinguish between true and false insulated glass?

With the development of glass processing industry, as well as people realize excellent  performance on insulated glass deeply, insulated glass in a widening range of  applications, in addition to insulated glass used in curtain wall, automobile, aircraft  and other applications, has begun to enter the homes of ordinary people. This is mainly  due to the application of insulated glass can improve the heat insulation and sound  insulation the effect of the doors and windows, doors and windows products can not only  shelter, but also has the remarkable energy saving effect, reduce the cost of heating in  winter and cooling in summer.

Insulated glass used in expanding constantly, people on the quality of insulated glass  are increasingly high requirements, how to grasp the opportunities for development of  the market, has become a insulated glass manufacturer on issues of concern to provide  high quality and reliable insulated glass. The processing technology of the basic  process of insulated glass is briefly analyzed.

First of all, introduce the types of insulated glass and five indexes of the national standard of insulated glass:

There are two kinds of insulated glass in the domestic market:
1.Channel aluminum insulated glass: this kind of insulated glass was introduced in 80s,  relatively mature, but the processing technology is more complex.
2.Aluminum strip insulated glass: this kind of insulated glass in China started late,  but the manufacturing process is simple, so a wide range of applications, the promotion  is very fast.

Second, the national standard of insulated glass in the five indicators;

l.initial dew point.
2.sealing test.
3.UV irradiation.
4.high temperature and humidity.
5.climatic cycle test.

According to the national standards, how to arrange our production, in order to achieve  the requirements of insulated glass? Because the two kinds of insulated glass has a lot  of similarities in the process, the analysis of process flow in common to them.

1.Glass cutting material:
The original glass is usually good quality clear float glass or other tinted glass, low-E  laminated glass, toughened glass,etc. Thickness about 3mm-12mm, glass can cutting by  hand or machine, but should guarantee the accurate size. This process workers in the  operation process, should always pay attention to the glass surface without scratch,no obvious defects, bubbles, and magazines inside.

2.Glass cleaning and drying;
Glass cleaning must use machine cleaning method, because the manual operation cleaning  cannot ensure the clean or not. Prior to the inspection of glass without scratch, to  ensure the adhesion of the sealant and glass, it is best to use deionized water. In  order to keep the water recycling, conservation of water resources, the water in the  filter, ensure the long-term use after cleaning. Through the glass light inspection,  inspection of glass surface is water, water stains and other stains, if there is water,  water stains and other stains, it is necessary to machine running speed, heating  temperature, air flow, brush gap adjustment, until it reaches the effect of intact so  far. After washing the glass should be within 1 hours. Assembled insulated glass, in  addition to ensure that the glass and glass between the friction scratches, it is best  to have a semi - finished glass storage car, the glass and the film separated.

3.Aluminum-type insulated glass assembly.
(1) The requirements of the environment: the temperature should be between 10-30  degrees.
(2) The relative humidity requirements: the insulated glass on the relative humidity  requirements slightly lower, the normal situation can be. However, it should be noted  that the desiccant should be selected manufacturers of qualified products to ensure the  effective use of desiccant. After the desiccant desiccation is best spent within  twenty-four hours, because the poly-sulfide permeability of the larger, poor sealing, so  to use double-sealed. With butyl rubber as the first seal, play a blocking gas role.  With two-component glue as the second seal, the main role is to bond, followed by gas  barrier effect. Practice has proved that single-channel sealed insulated glass life is  only about 5 years, and double-sealed insulated glass life can be as long as 20 years or  even 40 years, therefore, the development of double-sealed insulated glass is the trend  of the times.

4.Glass fit position:
Aluminum-type insulated glass, glass-bonded aluminum frame outside the edge and the edge  of the glass should be 5-7MM distance for the application of the second sealant, two- component glue should be evenly coated along the side to prevent the bubble , Painted  after the glass surface scraped off. At this point to complete the processing of  aluminum-type insulated glass.

5.Place the insulated glass:
The correct placement of the insulated glass will also affect the final quality of the  insulated glass, whether it is in production or in transit or at the site. First, the  design of the stacking frame takes into account the characteristics of the insulated  glass. Have a certain degree of inclination. But the bottom plane and side should always  be maintained at 90 degrees, so as to ensure that the insulated glass of the two glass  bottom can be placed vertically on the stacking frame. Also note that the bottom of the  glass should not be stained with grease, lime and other agents, because they are the  second insulated glass sealant will have different degrees of erosion, thus affecting  the insulated glass sealing performance.

In order to improve the effect sound insulation and heat insulation of insulated glass,  and now many manufacturers of insulated glass to take out the air inside of insulated  glass and put into the inert gas, this process makes the performance of insulated glass  has been further improved.

Finally, distinguish low quality forged and fake insulated glass has several of the most  important methods:

1. Replace the tempered glass with ordinary glass.
2. Replace the aluminum alloy bar with ordinary double-sided tape.
3. There is no addition of desiccant in the aluminum alloy barrier.
4. Only single-channel seal without double-sealing.
5. Replace the bimetallic glue with ordinary sealant.
