This kind of fogging phenomenon is actually caused by the unqualified manufacturing process of aluminum alloy door and window insulating glass. To understand the reasons for its formation and the solution,we must first understand the manufacturing process of insulating glass.
The basic manufacturing process of insulating glass consists of glass cleaning, molecular sieve screen -ing,butyl sealant coating,splicing,and second sealing adhesive.Every aspect is related to the choice of materials and the proficiency and quality of the operators.
1.Glass cleaning
Cleaning glass is a part of the production of insulating glass, and it is also one of the important links to ensure the sealing of insulating glass. If the oil stagnation and sweat on the glass cannot be thorou -ghly washed away,the adhesion of the sealant to the glass is greatly impaired,thereby reducing the sealing effect of the insulating glass.
2.The choice of desiccant The role of the desiccant: 1) Adsorption and sealing of moisture in the air 2)Adsorption of a volatile organic solvent 3)Adsorption of water vapor entering the air layer during the life of the insulating glass The purpose is to maintain a satisfactory initial dew point for the insulating glass. therefore,a qualified desiccant must simultaneously satisfy the three functions that the desiccant should have. If the desiccant has poor adsorption capacity and cannot effect-ively adsorb the moisture that has entered the air layer by diffusion,the moisture will accumulate in the air layer,the water pressure will increase,and the dew point of the insulating glass will rise,so that the possibility of atomization is extremely great.In additi -on,the choice of desiccant must take into account their respective properties.The choic -e of desiccant is directly related to the type of insulating glass glue selected,and must be considered together.
