A kind of processing technology of tempered glass

Abstract

The invention provides a processing technology of tempered glass, which belongs to the field of glass manufacturing. Including heating, cooling, slow heating, slow cooling, natural cooling, spray washing, cleaning, drying and other steps, through slow heating and slow cooling of the glass, through the transformation of high-temperature nickel sulfide to reduce the self-explosion rate of tempered glass, while using Aqua regia sprays and rinses the surface of the tempered glass, so that the nickel sulfide on the glass surface dissolves in the aqua regia, further reducing the self-explosion rate. This process has the advantage of greatly reducing the self-explosion rate of tempered glass.

Description

technical field [0001] The invention belongs to the field of glass manufacturing and relates to a processing technology of tempered glass. Background technique [0002] Tempered glass is safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. [0003] The expansion of nickel sulfide inside the tempered glass is the main reason for the self-explosion of the tempered glass. After the glass is tempered, the surface layer of the glass will form compressive stress. The inner core layer forms tensile stress, while compressive stress and tensile stress together form a balanced body. However, glass is a material with high brittleness, strong pressure resistance, but weak tensile property, so most glass breakage is caused by changes in tensile stress. When the nickel sulfide crystal (in ...
