The general use of quartz glass tube
High temperature resistant quartz tube, also called quartz glass tube, is a special industrial technical glass made of silica, which is a very good foundation material. At the same time, quartz glass has a series of excellent physical and chemical functions. As a professional quartz glass tube manufacturer, let Quartz Products Co., Ltd. product factory explain the detailed characteristics of quartz glass tube for you.
1. High temperature resistance
The softening point temperature of the quartz glass tube is about 1730°C, and it can be used for a long time at 1100°C, and the maximum operating temperature can reach 1450°C in a short time.
2. Corrosion resistance
Except for hydrofluoric acid, quartz glass tube does not react chemically with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. In particular, its chemical stability at high temperatures is comparable to any other engineering materials. incomparable.
3. Good thermal stability
The thermal expansion coefficient of the quartz glass tube is extremely small, and it can accept drastic temperature changes. The quartz glass tube is heated to about 1100°C, and it will not break when placed in water at room temperature.
4. Good light transmission function
The quartz glass tube has a good light transmission function in the entire spectrum band from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectrum region, the maximum transmittance can reach 80 or more.
5. Good electrical insulation function
The resistance value of the quartz glass tube is equivalent to 10,000 times that of ordinary glass. It is an excellent electrical insulation material and has outstanding electrical functions even at high temperatures.
