Quartz smoke nails are made of quartz glass, which is a single-component silica glass, usually divided into two categories: transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass has only a few bubbles, and has a fairly high optical uniformity and transparency. It is made of crystal box silicon tetrachloride as raw material and melted at high temperature.
Introduction
Quartz glass tube is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.
Features
The characteristics of our company’s processing of quartz glass: high flatness (plus or minus 0.002MM), high parallelism (plus or minus 0.002MM), small tolerance (plus or minus 0.01), wear resistance, long service life, and increased product quenching procedures during processing , Which greatly increases the service life of quartz glass and helps customers reduce costs. Quartz glass is a single-component silica glass. It is weakly acidic, so it is not resistant to alkali. And acid resistance, except for hydrofluoric acid and hot phosphoric acid.
The surface roughness of the workpiece after polishing can reach Ra0.0002; the flatness can be controlled within 卤0.002mm.
Performance introduction
鈶?High temperature resistance. The softening point temperature of quartz glass is about 1730鈩? it can be used for a long time at 1100鈩? and the temperature can reach 1450鈩?for short time.
鈶?Corrosion resistance. Except for hydrofluoric acid, quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially, its chemical stability at high temperatures is impossible for any other engineering material. Comparable.
鈶?Good thermal stability. The thermal expansion coefficient of quartz glass is extremely small, and it can withstand severe temperature changes. When the quartz glass is heated to about 1100掳C, it will not burst when placed in water at room temperature.
鈶?Good light transmission performance. Quartz glass has good light transmittance in the entire spectrum band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectrum.
鈶?Good electrical insulation performance. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures.Quartz Special Products quotation
