The basic production process of insulating glass is composed of glass cleaning, molecular sieve irrigation, butyl sealant coating, laminated, coated second sealant and other links. Among them, the choice of materials, the proficiency of operators and the quality of processing have an important impact on insulating glass doors and Windows.

The first link of insulating glass production is cleaning glass, which is one of the most important links to ensure the tightness of insulating glass. The glass or material with oil lag and sweat is not easy to be thoroughly cleaned off, resulting in the adhesive force of sealant on the glass will be greatly weakened, thus reducing the sealing effect of insulating glass. The degree of attention to cleaning glass is not enough, often cause a large number of unqualified products into the market. Hollow laminated glass

Selection of insulating glass adhesive

The edge seal of insulating glass is very important. Once it is not done well, it will mean that doors and Windows lose their due function, not only the energy-saving performance of doors and Windows cannot meet the requirements, but also consumers can not see outside through the foggy air layer, affecting the transparency of hollow glass, thus reducing the heat insulation effect. In addition, glass doors and Windows produce fog, will make the inner surface of the glass mildew or alkali, produce white spots, seriously affect the appearance of the quality of hollow glass. Therefore, the selection of insulating glass sealant should meet the requirements of national or industry standards. At the same time, the first and second sealant of double layer insulating glass should be suitable for each other, and should not be miscible or react, otherwise it will lead to glass surface pollution and even aging.

Choice of desiccant

The properties of desiccant must be considered comprehensively when choosing desiccant. The selection of desiccant is directly related to the type of insulating glass adhesive selected, and must be considered in combination.

Double insulating glass coating

The composite piece is the middle ring of making double layer insulating glass. The butyl adhesive before laminating plays an important role in the comprehensive quality of insulating glass. If there is a gap between the two sealant, it will cause air leakage. Apply the second sealant can not be omitted. Sometimes after installation and use for a period of time, the effect of environmental temperature changes, sun exposure and wind pressure, sealant will form cracks - water vapor may slowly enter the rubber layer, forming fog, inducing Windows and doors glass quality problems.
