  optical glass:

   is a glass material used to manufacture lenses, prisms, mirrors, windows, etc. of optical instruments or mechanical systems. Including colorless optical glass (usually referred to as optical glass), colored optical glass, radiation resistant optical glass, radiation protection glass and optical quartz glass, etc. Optical glass has a high degree of transparency, a high degree of uniformity in chemistry and physics (structure and performance), and has specific and precise optical constants. It can be divided into silicate, borate, phosphate, fluoride and chalcogenide series.

  Cold processing technology:   A kind of use of chemical vapor heat treatment and monolithic soda lime silica glass to change its original molecular structure without It affects the original color and light transmittance of the glass to make it reach the ultra-hardness standard, and meets the fire-proof requirements under the impact of high-temperature flame, and its manufacturing method and special equipment. It is made of the following components in weight ratio: potassium salt vapor (72% to 83%), argon (7% to 10%), gaseous copper chloride (8% to 12%), nitrogen (2 %~6%). It includes the following process flow: cutting with soda-lime silica glass as the substrate, and cold processing of fine edge grinding → chemical vapor heat treatment of the cold-processed soda-lime silica glass → coating the surface of the soda-lime silica glass with a fire protection film → The surface of soda lime silica glass is subjected to special physical tempering treatment. A special thermal decomposition gasification equipment is composed of a cylinder body, a cylinder head fitted with it, and a reaction kettle integrally connected with the cylinder head.
