Abstract

The invention belongs to the technical field of sandwich glass production, and particularly relates to a production technology for ultra-thin sandwich glass. The technology includes the following steps that the sandwich glass is placed on a working table of an ultra-thin sandwich glass pre-pressing quick-cooling equipment; a flattening roll of the ultra-thin sandwich glass pre-pressing quick-cooling equipment rotates along with a second fixing frame, makes contact with the sandwich glass, and presses the sandwich glass in advance to dispel air bubbles in the sandwich glass; a quick-cooling cavity of the ultra-thin sandwich glass pre-pressing quick-cooling equipment rapidly cools the sandwich glass; a first piston plate in a first fixing frame of the ultra-thin sandwich glass pre-pressing quick-cooling equipment moves vertically and makes water in the first fixing frame, the quick-cooling cavity, a condensing cavity, a first pipeline and a second pipeline circulate; the cooled sandwichglass is taken out, packaged and then stored in a warehouse. Through the production technology, the production efficiency of the sandwich glass is improved effectively, and the yield of the produced sandwich glass is increased effectively.

Description

technical field

[0001] The invention belongs to the technical field of laminated glass production, in particular to a production process of ultra-thin laminated glass. Background technique

[0002] Laminated glass is composed of two or more pieces of glass with one or more layers of organic polymer intermediate film sandwiched between them. After special high-temperature pre-pressing and high-temperature and high-pressure processing, the glass and the intermediate film are permanently bonded together. For composite glass products, the commonly used interlayer film for laminated glass is PVB, a polymer material formed by polyvinyl butyral resin plasticized and extruded by a plasticizer. The appearance is a translucent film, free of impurities, smooth surface, and Certain roughness and good flexibility, good adhesion to inorganic glass, transparent, heat-resistant, cold-resistant, moisture-resistant, high mechanical strength, etc., is currently the best adhesive for manufactur...

Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Such as Figure 1 to Figure 7 Shown, a kind of ultra-thin laminated glass production process of the present invention, this process comprises the following steps:

[0030] S1: Place the laminated glass on the workbench of the ultra-thin laminated glass pre-press quick cooling equipment;

[0031] S2: The leveling roller of the ultra-thin laminated glass pre-pressing quick cooling equipment in S1 rotates with the No. 2 fixed frame and contacts with the laminated glass. The leveling roller pre-presses the laminated glass and drives away the air bubbles in the laminated glass. The impact of the laminated glass makes the interlayer film of the laminated glass and the glass sheet more tightly combined, and at the same time makes the air bubbles ...
