What is the relationship between the high temperature resistance of high temperature glass

Click: -Time:2019-09-09 09:11
High temperature resistant glass, such as quartz glass and borosilicate glass, are commonly used in industry. However, the high temperature resistance of high temperature resistant glass and what is related to the users are not particularly clear. Our company will explain this problem to you so that users can have a better understanding of this product and make correct choices when purchasing it.
 
Firstly, the chemical composition determines the high temperature resistance. For example, SiO 2, B2O 3, A12O3, ZrO 2, ZnO and MgO can increase the high temperature resistance of glass, reduce the thermal expansion coefficient of glass and improve the thermal stability of glass.
Secondly, related to the processing technology, different high-temperature glass processing methods are different. After heat treatment, annealing, quenching and other different processing, the temperature and other mechanical properties of glass can be increased accordingly.
Moreover, it is related to processing technology and equipment. The same raw materials, after exquisite processing technology, advanced equipment processed glass high temperature performance is far superior.
Finally, the use process also affects the performance of high temperature glass. If the glass operates in a critical lower state for a long time or is often extremely cold and hot, it will affect the thermal resistance of glass.
