Introduction
Quartz glass tube is made of silicon dioxide in special industrial technology glass, is a very good base material.Quartz glass has a series of excellent physical and chemical properties.
Our company processing quartz glass features: high flatness, plus or minus 0.002 MM), high parallelism (plus or minus 0.002 MM), small (0.01) plus or minus tolerance, wear-resisting, long service life, increase product processing quenching process, greatly increase the service life of the quartz glass, help customers reduce costs.Glass and quartz glass is silicon dioxide single components.Weak acid, alkali not so.And acid, except hydrofluoric acid, hot phosphoric acid.
Workpiece surface roughness after polishing can achieve Ra0.0002;Flatness can be controlled within + / - 0.002 mm.
