Precautions for using quartz glass
- Quartz glass products are valuable materials and must be handled gently with great care when in use;
- All kinds of quartz glass have a limit of applicationtemperature, and when it is used, the temperature should not exceed that limited temperature, otherwise the devitrification or deformation will happen;
- Quartz glass to be used at high temperatures must be wiped clean before use. It can be soaked in hydrofluoric acid with 10 percent purity or washing solutionsand then cleaned with high-purity water or treated with alcohol. Thread gloves should be worn during operation, and it is not allowed to touch the quartz glass directly with hands;
- Continuous use of quartz glass productsat high temperatures is allowed, which is beneficial for extending the lifespan of quartz glass and improving its thermal performance. On the contrary, intermittent use of quartz glass products at high temperatures is limited;
- Quartz glass has goodthermal stability and can withstand sudden temperature changes. However, in actual use, due to residual stress and product shape differences, thermal stability varies to some extent, which should be paid attention to;
- Quartz glass is an acidic material and should be strictly avoided from contact with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.) at high temperatures, otherwise its resistance to crystallization will be greatly reduced.
