Abstract

The invention relates to the technical field of tempered glass, and discloses a tempered glass processing technology which comprises the steps of heating, cooling, spraying of potassium nitrate liquid glue, slow heating, slow cooling, natural cooling, spray washing, cleaning, drying and the like, potassium nitrate is added into the liquid glue, the prepared potassium nitrate liquid glue is sprayed on the surface of glass, and the tempered glass is obtained. The following slow heating and slow cooling comprise a temperature maintaining step, so that nickel sulfide on the outer side of the glass can be neutralized and converted with potassium nitrate liquid glue, the liquid glue is automatically decomposed at high temperature, the quality of the glass is not influenced, and the quality of the glass is improved by matching gamma ray irradiation and ultrasonic treatment. Nickel sulfide in the glass is promoted to be converted into a low-temperature phase beta-NiS from a high-temperature phase alpha-NiS, and spontaneous explosion of the prepared tempered glass is reduced.

Description

technical field [0001] The invention relates to the technical field of tempered glass, in particular to a tempered glass processing technology. Background technique [0002] Tempered glass is a type of safety glass whose strength is increased by controlled heat treatment or chemical treatment of ordinary glass. Tempering puts the outer surface in compression and the inner surface in tension. This stress causes the glass to break into small clumps of particles, rather than into jagged shards like flat glass (aka annealed glass). Particle shards reduce the likelihood of damage. [0003] The expansion of nickel sulfide inside the tempered glass is the main reason for the self-explosion of the tempered glass. Since 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 balance body. However, glass is a material with high brittleness and strong ...
