Use Notices of round fused quartz glass plate

 1. Do not operate in temperature beyond quartz maximum working temperature for long time.

    Otherwise, products will deform crystallization or become softening. 

 2. Clean the quartz products before high temperature environment operation . 

   Firstly soak the products in 10% hydrofluoric acid, then wash it with high purity water or alcohol .

   Operator should wear thin gloves , direct touch with the quartz glass by hand is inhibited.

 3. It is wise to extend the lifespan and thermal resistance of quartz products via continuous use 

    within high temperature environment. Otherwise, interval use shall shorten products lifespan.  

 4.  Try to avoid touch with alkaline substances (such as water glass, asbestos, potassium and sodium compounds, etc.)

    when employing quartz glass products in high temperature, which is made of acid material. 

    Otherwise product anti- crystalline properties will be greatly reduced.
