Abstract

El vidrio fino está encontrando aplicación creciente en laminados. Sin embargo, los métodos convencionales de procesamiento tienen defectos cuando se aplican a vidrio muy delgado. Esta invención proporciona un método mejorado para curvar y laminar vidrio delgado. Múltiples hojas de vidrio fino se apilan en un único molde. Una placa de presión de superficie completa macho, que comprende una lámina curvada de vidrio más grueso, se coloca sobre las láminas de vidrio delgado. A medida que se calienta el vidrio, la masa añadida de la placa de prensado ayuda en el curvado. La placa de prensado también se puede utilizar en el proceso de laminación para evitar arrugas durante el laminado. La placa de prensado está compuesta por una composición de vidrio que tiene un punto de transición vítrea más alto que el vidrio delgado, de manera que la placa de prensado no se ablande ni deforme a medida que se dobla el cristal delgado. La placa de prensado está formada por métodos convencionales de curvado de vidrio.Fine glass is finding increasing application in laminates. However, conventional processing methods have defects when applied to very thin glass. This invention provides an improved method for curving and laminating thin glass. Multiple sheets of thin glass are stacked in a single mold. A male full surface pressure plate, comprising a thicker curved glass sheet, is placed on the thin glass sheets. As the glass is heated, the added mass of the pressing plate helps in bending. The pressing plate can also be used in the lamination process to prevent wrinkles during lamination. The pressing plate is composed of a glass composition that has a glass transition point higher than the thin glass, so that the pressing plate does not soften or deform as the thin glass bends. The pressing plate is formed by conventional methods of glass bending.
