Раструбное кольцо из боросиликатного стекла устойчивое к гидрофторной

Characteristics:
1.High temperature stability: Quartz glass is with pretty less shrinkage coefficient which can withstand temperature racing up shortly. The quartz glass will be no breakage if place into normal temperature immediately after heating at 1100℃.
2.High Acid Resistance: Except hydrofluoric acid, quartz glass hardly react with other acid substances. The acid resistance is 30 times of ceramics and 150 times of stainless steel, especially its chemical stability at low temperature, which is unmatched by any other engineering materials.
3.The mechanical properties of quartz glass are better than that of hard glass and ceramics, and its strength increases with increasing temperature, reaching a maximum when approaching the annealing temperature.
4.Good electrical insulation: The resistance value of quartz glass is 10,000 times that of ordinary glass. It is an excellent insulating material and has good electrical properties even at low temperatures.
