The softening point of quartz glass is about 1730 ℃. It can be used at 1100 ℃ for a long time, and the maximum temperature can
reach 1450 ℃ in a short time.
2.Good thermal stability
The coefficient of thermal expansion of quartz glass is very small, and it can withstand drastic temperature changes. When the quartz glass is heated to about 1100 ℃, it will not burst into normal temperature water.
3.Good light transmittance
Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance is more than 80.
4.Good electrical insulation
The resistance value of quartz glass is 10000 times that of ordinary glass. It is an excellent electrical insulating material and has good insulating performance even at high temperature.
5.Corrosion resistant
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 its chemical stability at high temperature, which is
Customized product display
Quartz glass rods are used to make special optical fibers and devices
The continuous melting method can be used to produce transparent quartz tube and transparent quartz rod with good appearance and size by using raw materials with different characteristics, and the oh value can be adjusted by heat treatment. It can be used for the production of mercury lamp, halogen lamp and other electric light source quartz lamp, electric heating outer tube, semiconductor product material, optical fiber base tube, etc.
instructions
Precautions for use of quartz glass: 1. Quartz glass products are valuable materials, so they must be handled with care; 2. All kinds of quartz glass have a maximum service temperature, which should not be exceeded, otherwise crystallization or softening deformation will occur; 3. The quartz glass that needs to be used at high temperature must be wiped clean before use. It can be soaked in 10% hydrofluoric acid or lotion, then cleaned with high purity water or treated with alcohol. Wear fine gloves during operation, and do not touch quartz glass directly with hands; 4. Continuous use of quartz glass products is allowed under high temperature, which is beneficial to prolong the service life of quartz glass and improve the temperature resistance. On the contrary, the intermittent use of quartz glass products under high temperature has limited use times; 5. Although quartz glass has high thermal stability, it can withstand sharp temperature difference. However, due to the difference of residual strain and product shape, there are some differences in thermal stability in practical use, which should be paid attention to; 6. Quartz glass is acidic material. When it is used at high temperature, it should be strictly avoided to contact with alkaline substances (such as sodium silicate, asbestos, potassium and sodium compounds, etc.), otherwise its anti crystallization performance will be greatly reduced.
