Pay Attention To The Cleaning And Maintenance Of Quartz Glass

Mar. 11, 2019

Quartz glass is a single-component amorphous material of silica. Its microstructure is a simple network composed of silica tetrahedral structural units. Due to the large chemical bond energy of Si-O, the structure is very close, so optical quartz Glass has unique properties, especially transparent quartz glass, which has excellent optical properties and excellent transmittance in the continuous wavelength range from ultraviolet to infrared radiation.

Quartz glass has a very low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay properties, excellent UV-transparent spectral properties, and visible and near-infrared spectroscopy. Performance and has higher mechanical properties than ordinary glass.

In the cleaning and maintenance of quartz glass, we should pay attention to the following points:

1. The products of quartz glass are very expensive, so we must be very careful when using them, we must take them lightly;

2. If quartz glass needs to be used at high temperatures, we must wipe it off before use. It can be soaked in a solution containing 10% hydrofluoric acid and then treated with high purity water or alcohol. Wear thin-line gloves during operation to avoid direct contact with quartz glass by hand;

3, different quartz glass products have different high use temperatures, we can not exceed this temperature when used, otherwise it will cause the product to devitrify or soften the deformation;

4. Quartz glass is an acidic material. When it is used at high temperature, it must avoid contact with alkaline substances, otherwise it will greatly reduce its anti-crystallization property;

5, quartz glass material, although it has extremely high thermal stability, can withstand sudden changes in temperature. However, in actual use, there are corresponding differences in thermal stability due to residual strain and product shape, so care should be taken when using it.
