Do Not Ignore The Cleaning And Maintenance Points Of Quartz Glass

Dec. 26, 2018

Quartz glass like Fused silica Cylinder Lenses is an acidic material. Except for hydrofluoric acid and hot phosphoric acid, it is inert to any other acid and is a good acid-resistant material. The degree of corrosion of the quartz glass by the alkali and the salt at room temperature is also extremely small, so the use of quartz glass in these reagents is not excluded. Quartz glass has the characteristics of being non-hygroscopic and not weathering. It is very sensitive to all alkali or alkaline earth compounds, and the slight amount of these compounds promotes the crystallization of quartz glass at high temperatures.

Therefore, 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. Thin line gloves should be worn 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 (such as asbestos, water glass and potassium and sodium compounds), otherwise it will greatly reduce its anti-crystallization properties. ;

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.
