No matter what shape and size, ZCQ will try to realize customer’s requests.

Quartz product Use Notice
1.Be careful and gentle when taking and placing the quartz glass products, which is made of expensive material .
2.Do not operate in temperature beyond quartz maximum working temperature for long time. Otherwise, products will deform crystallization or become softening.
3 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.
4 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.
5 . Thermal stability of quartz products could vary from product to product due to different shapes and residual strain,although the quartz glass material is best known for high thermal stability to withstand sudden changes in temperature intense ,
6 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.
