Abstract

This invention belongs to the glass industry, it can be used for producing bent or straight three layer glass for vehicles and civil engineering. The novelty of this invention is that the third inner layer of the glass pack consists of a polymer acrylic mixture.

Description

The invention relates to the glass industry and can be used in the manufacture of curved and straight three-layer non-destructive glass for vehicles and construction work.

There is a known method of producing a three-layer glass-triplex described in K. Strazd's book Glass Technology, V. / 'Science, I9? 8. , for the production of triplex using an adhesive film of organic origin (cellon, vinylite, plexiglass a butanol). The film is sandwiched between two sheets of glass and, after a period of heating, adheres to the glass to form a three-layer glass.

A glass yr _a major drawback is that it has low thermostability properties and will result at temperatures aakstai glass it takes atspalvį- lovage ^ autumn it reduces the transparency.

The object of the present invention is to develop a new triple-layer glass-triplex technology, which would produce high thermal stability properties, meet all optical and safety requirements of such glass, and reduce the power consumption in production.

This is achieved by taking two defective, well annealed, uniformly curved glasses of the same configuration, and very clean surfaces.

The inner sides of the molded glass panes are coated with K-2 alcohol mixture. (G K-2 is taken per kg of alcohol). At the edges of the glass sheets, a rubber or plastic gasket is laid to form a thickness of pmra. One edge of the glass is left open (without gasket). The glasses are then sewn onto each other and pressed together with special clamps.

A polymeric acrolate mixture is poured into the inside of the package through the left space. It requires 1.6 kg of acrolate mixture per square meter of glass per keto meter. Atmospheric pressure strongly compresses the sheets against each other and displaces the remaining air inside the package.

The glass unit is placed under LtūF-BO type UV lamps and irradiated for 35-4-0 minutes. The panes are then left to cool for a while at room temperature. The glass holders are removed from the package. The resulting layer of polymers inside the glass modified 4443 B forms a clear, durable film that is resistant to temperature changes and mechanical stress.

The production of triple glazing - triplex is simple, tested in practice and easily absorbed by the glass industry. The products have been tested in operation and in laboratory tests.

DEFINITION OF DISPOSAL A method of producing triple glazing is a triplex process in which a double-glazed unit is formed by a polymeric filler in which the third middle layer of the glass consists of a hardened polymeric acrolate mixture which is sandwiched between two sheets of glass.
