      The performance of the quartz glass in glass production factory in Qingdao

      Industry News2016-05-17

      Familiar to everybody to glass, they are active in everyone's life and work, so for quartz glass in glass, you have to know? Glass production factory in Qingdao are acting collectively, to inspect it.

      2, thermal performance: quartz glass is a kind of low expansion coefficient of glass, has a very high reting resistance at the same time, can satisfy the heat resistance of 700-700 ℃ or more for a long time to use the highest heat resistance of 1500 degrees. And quartz glass or super poor conductor.

      3, optical performance: quartz glass and common glass is an important difference between it within the entire spectrum of good permeability, has its in the ultraviolet and the permeability in deep ultraviolet spectrum is generally does not have optical glass.
