Quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, optimum UV transmission performance, and visible light transmission and near infrared spectroscopy. Performance, and has higher mechanical properties than ordinary glass. Therefore, it is one of the indispensable materials in the modern technology of space technology, atomic energy industry, national defense equipment, automation system, and semiconductor, metallurgy, chemical, electric light source, communication, light industry, building materials and other industries.
Quartz glass is made by natural crystalline quartz (crystal or pure silica) or synthetic silane at high temperature. The molten product has excellent processing properties. In the extremely high viscosity range, the tubes and rods can be processed like ordinary glass, and high-speed mechanical tools can be used for grinding tools made of diamond or silicon carbide. Processing to make instruments and special products of various complex shapes. The performance of quartz glass depends mainly on its purity, followed by the process or thermal system. The presence of trace impurities will have a major impact on the performance of quartz glass; at the same time, due to the slight negligence of the process or thermal system, it will bring a variety of defects to the appearance quality, resulting in a large number of waste products.
The safety protection system includes various mechanical and electrical protections. The five major components include: safety gear, speed limiter, door lock, buffer, rope gripper and uplink overspeed protection.
