A production process of ultra-thin laminated glass

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...

AI Technical Summary

Problems solved by technology

[0003] Because of the physical characteristics of PVB composite materials, the existing laminated glass production process uses closed high-temperature and high-pressure treatment of the interlayer adhesive material, using high temperature to soften the adhesive material, and extruding the air bubbles in the interlayer through high-pressure treatment. On the one hand Dealing with air bubbles requires multiple equipments to cooperate with each other. Closed heating treatment will cause excess energy waste, increase production costs, low production efficiency, and fail to meet market demand; on the other hand, uniform extrusion will lead to different direction of air bubble extrusion. Definitely, it is easy to directly cause cracks in the laminated glass. After the processing is completed, it needs to be shelved for cooling. During this period, the physical properties of the laminated glass are unstable, and it is easy to be disturbed by the outside world to produce defective products. The yield rate of the laminated glass produced is not high, resulting in low income. Serious waste of cost
