Processing of laminated transparent panels
Abstract
Abstract Laminated transparent panels are normally made by assembling sheets of rigid transparent material, at least one of which is glass, with intervening layers of transparent plastics material which bond the rigid sheets together when the assembly is heated. If the panel is cooled too quickly after the bonding process, as by being plunged into cold water, the glass tends to break. If the panel is cooled too slowly, however, crystallites tend to form in the bonding material thus reducing the transparency of the panel. The invention aims to avoid these difficulties by cooling the heated panels at intermediate rates, a liquid with a thermal conductivity less than that of water being applied to the panel. The liquid may have a thermal conductivity of between 2.0 and 4.0 joule cm/cm2 sec. *C, and a temperature between 15*C and 35*C.
