How many types of quartz glass tubes?
Quartz tubes can be roughly divided into the following types: transparent quartz tubes (outer diameter 1.5 mm - 300 mm), UV filter quartz tubes, color quartz tubes, etc.
Chemical properties: High temperature resistance
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.
preservative
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 to compare with that.
Physical properties
1. Good thermal stability
Quartz glass tubes 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.
2. Good light transmission
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.
3. Good electrical insulation
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 insulation properties even at high temperatures.
Quartz glass is widely used in various fields such as electric light source, semiconductor, optical communication, military, metallurgy, building materials, chemistry, machinery, electric power, environmental protection, etc. due to its excellent physical and chemical properties.
