The basic production process of insulating glass

1. 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 sealing of insulating glass. If the stain on the glass can not be thoroughly cleaned off, the adhesive force of the sealant on the glass will be greatly weakened, thus reducing the sealing effect of the insulating glass. Choosing a insulating glass production line produced by a professional manufacturer can avoid the occurrence of such phenomena.

2. Selection of desiccant and sealant

When selecting desiccant, the performance of desiccant must be comprehensively considered, and the selection of desiccant is directly related to the insulating glass glue selected, which must be comprehensively considered. If the edge seal of the insulating glass fails, it means that the doors and Windows lose their due function, not only the energy-saving performance of the doors and Windows can not meet the requirements, but also consumers can not see through the fog of the air layer, affecting the transparency of the insulating glass, and reduce the insulation effect. Long-term fog will cause mildew or alkali accumulation on the inner surface of the glass, resulting in white spots, which seriously affect the appearance quality of the insulating glass. It can be seen that the selection of high-quality insulating glass equipment is the key to prevent insulating glass fog, the selection of insulating glass sealant, should meet the national or industry standards, and the first and second insulating glass sealant should be suitable, can not be miscible or react, otherwise it may lead to glass surface pollution, and even aging.

3. Composite insulating glass

The composite piece is the middle part of the insulating glass. The coating of butyl adhesive before laminating determines the comprehensive quality of insulating glass. If there is a gap between the two sealant, it will cause air leakage. At the same time, it should be noted that if the second sealant is applied too thin, after the installation and use of a period of time, by the environmental 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 rubber layer, forming fog, so that the sealant loses its sealing effect.

To sum up, when choosing insulating glass equipment, you should choose a professional manufacturer, choose high-quality insulating glass production line and insulating glass gluing machine, which can greatly improve the quality of insulating glass, thus greatly increasing the life of doors and Windows.
