Optical glass, cold working
optical glass:
is a glass material used to build an atmosphere for manufacturing lenses, prisms, reflectors, 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 proof glass with small power consumption, optical quartz glass, etc. Optical glass has high transparency, high uniformity in chemistry and Physics (structure and performance), and specific and accurate optical constants. It can be divided into silicate, borate, phosphate, fluoride and chalcogenide series
Cold working technology:a kind of super hard fire-proof glass, its manufacturing method and special equipment, which uses chemical vapor phase heat treatment and single sodium calcium silicate glass to change its original molecular structure without affecting the original color and transmittance of the glass, so that it can meet the super hardness standard and meet the fire-proof requirements under the impact of high-temperature flame. It is made of components that are more and more difficult to describe by weight in this process: potassium salt vapor (72% - 83%), argon (7% - 10%), gaseous copper chloride (8% - 12%), nitrogen (2% - 6%). It includes the following process flow: cold processing of cutting and fine grinding with soda lime silica glass as the substrate → chemical vapor heat treatment of soda lime silica glass after cold processing → treatment of plating fireproof protective film on the surface of soda lime silica glass → special physical tempering treatment on the surface of soda lime silica glass. The special thermal decomposition and gasification equipment is composed of the cylinder block and its cylinder head, and the reaction kettle integrated with the cylinder head
