According to the Chinese epoxy resin industry online, in the Shenzhou seven spacecraft, Hubei Jingzhou feilihua Quartz Glass Co., Ltd provides quartz glass fiber, glass fiber is also used in the current batch of "cover and a protective layer of God seven" space communication line. According to the Chinese Epoxy Resin Industry Association experts, the predecessor of Shashi feilihua quartz glass factory in 1979, according to the Department of building materials industry do the task, in the country's first successful trial of high purity quartz fiber and silicone quartz fiber. Since then, it has forged a indissoluble bond with the construction of the national defense industry. Over the past 30 years has developed the production of superfine quartz fiber, high strength programmable quartz fiber model, fused quartz fiber, hollow quartz fiber quartz and other 9 kinds of new materials, widely used in aerospace and other defense high-tech fields, provide supporting materials for many national key weapons and "Shenzhou" spacecraft 1 to 7. Technology center of Jingzhou feilihua Quartz Glass Co., Ltd. manager Ouyang Baohua introduced, the ablation resistance, with heat insulation function, strong permeability and strong waves and high strength glass fiber has many characteristics of quartz, quartz glass fiber provided by the company through the transformation for the "Shenzhou seven" parts.

First of all, the lens of Shenzhou seven camera is made of quartz glass. According to experts of China epoxy resin industry association, as the rocket has 5 engines in the tail cabin of the two stage, the working environment of the camera is very bad. The developers have protected the whole body against heat and vibration. The lenses are made of quartz glass with high temperature resistance, mainly for high temperature resistance. According to China Epoxy Resin Industry Association experts, the company provides quartz glass can withstand more than 1200 degrees Celsius high temperature. Similarly, heat insulation material on the shell of the spacecraft is made up of quartz, fiberglass and other materials. Secondly, the quartz glass has strong wave permeability, and the quartz glass fiber provided by the company is mainly used to make the hatch cover of the re-entry module. The hatch cover is in fact an information receiver, and all the information on the ground and on the satellite is made of this layer of quartz glass, and the hatch cover is connected with the astronauts and other equipment inside. According to the company's technical personnel Ouyang Baohua introduction, their production of quartz glass fiber properties have been finalized, standardized production. Is currently the only one for the Shenzhou series of spacecraft to provide quartz glass fiber business.

Quartz glass is made up of a single component of silica. This glass hardness is big, can reach the Mohs grade seven, low expansion coefficient, high temperature resistance, chemical stability, electrical insulation is better, in addition to hydrofluoric acid, hot phosphoric acid, the general acid has good acid resistance. Transparent quartz glass has excellent UV Vis linear energy and optical properties. Used in the manufacture of optical instruments, electrical equipment, medical equipment and high temperature resistant and corrosion resistant chemical instruments. High purity silica glass can be used to make optical fibers. With the development of semiconductor technology, quartz glass has been widely used in various processes of semiconductor manufacturing. For example, the Czochralski method transforms polycrystalline to monocrystalline silicon; the cleaning bath used in cleaning; diffusion tubes used for diffusion; grooved vessels; clock rings used in ion implantation and so on. Quartz glass is a kind of special glass containing only one component of silica. Due to differences in species, process, material. According to the Chinese Epoxy Resin Industry Association experts, quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation properties, ultrasonic delay low and stable, through the UV spectrum of the best performance and penetration of visible light and near infrared spectral properties, and the mechanical properties is higher than that of ordinary glass. It is the modern cutting-edge technology in space technology, atomic energy industry, defense equipment and automation system, as well as indispensable semiconductor, metallurgy and chemical industry, communication, electric light source, light industry, building material industry in one of the fine materials.
