Repair and maintenance:

 

A. the mirror glass is suitable for damage. Handle it carefully when installing the mirror.

 

B. the mirror is a flow reaction equipment used to observe liquid, gas, steam and other media, and its window glass shall be kept clean and dust-free.

 

C. temperature resistance and pressure resistance of glass have certain limitations. Temperature resistance: tempered borosilicate glass: ≤ 180 ℃, quartz glass: 800 ℃. Pressure resistance: tempered borosilicate glass sheet: ≤ 3.0MPa,

 

Quartz glass sheet: ＜ 10.0MPa, tempered borosilicate glass cylinder: ＜ 1.0MPa, quartz glass cylinder: ＜ 1.6Mpa. The allowable temperature of glass is less than 60 ℃ ~ 100 ℃

 

D. in case of any crack or damage, it must be replaced immediately.
