The glass tempering furnace uses physical or chemical methods to form a compressive stress layer on the surface of the glass and a tensile stress layer inside; when the glass is subjected to an external force, the compressive stress layer can offset part of the tensile stress to avoid glass breakage, thereby improving glass strength.
Processing principle: the high-temperature heating element in the glass tempering furnace radiates radiation of a certain wavelength. This radiation is directly radiated to the glass surface, the furnace insulation material and the roller, etc. The latter is heated and generates radiation, and the heat is radiated to the glass surface Part of it is absorbed by glass and part of it is reflected (transparency of transparent glass is less than 6% to 8%, and the rest absorbs part or most of it according to the condition and blackness of the glass surface). Glass conduction heating is mainly manifested in two aspects:
