The key to making qualified hollow glass

To make hollow glass, first of all, the thickness of the glass should be selected according to the size of the glass, and whether to use tempered glass, laminated glass, coated glass, etc. is determined according to the needs of use. Before production, check whether the glass has deteriorated such as anti-alkali, oxidation, etc., and do not use the deteriorated glass.

Butyl glue is the main link to ensure the long-term sealing of hollow glass. It is necessary to choose qualified butyl glue and good quality butyl glue glue machine to ensure that the butyl glue on the hollow aluminum frame is continuous and uniform (no broken strips).

Structural adhesives are used to ensure the strength of hollow glass, and qualified structural adhesives must be selected with sufficient thickness. Coated glass that needs to be removed from the LOW-E film should be glued after removing the film.

Hollow aluminum frame production The hollow glass aluminum frame is preferably made by integral bending, which can overcome the weakness of the gusseted aluminum frame that is prone to leakage at the corners. If you use gusset to make a hollow aluminum frame, you should pay attention to check whether the butyl glue is applied at the connection between the gusset and the aluminum strip. The back of the four gussets should be blocked with butyl glue before applying structural glue.

To make qualified hollow glass, fill in inert gas (such as argon) after lamination. In addition to improving the thermal insulation and sound insulation functions of the glass, argon has a 100% drying function, which can ensure the balance of the internal and external pressures of the glass, so that the hollow glass does not fail or oxidize. Because the molecular sieve put into the insulating glass is certain and the ambient humidity is different, this will lead to the difference between the internal and external pressure of the glass. The glass will be stressed, resulting in distortion of the glass surface, failure of condensation, and increased after-sales service costs. Filling the protective gas with argon will also prevent the insulating glass from oxidizing.
