Quartz glass tube is a special industrial technology glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, such as:
The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C. The maximum use temperature can reach 1450 ° C in a short time.
In addition to 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 at high temperatures, it is impossible for any other engineering materials. Comparable.
3, good light transmission performance
Quartz glass has good light transmission performance in the entire spectral range from ultraviolet to infrared, and the visible light transmittance is above 93%, especially in the ultraviolet spectral region, and the maximum transmittance is over 80.
4, good thermal stability
Quartz glass has a very small thermal expansion coefficient and can withstand severe temperature changes. The quartz glass is heated to about 1100 ° C and will not burst when placed in normal temperature water.
5, good electrical insulation performance
Quartz glass has a resistance value 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.
