Quartz ring

Quartz ring is a special industrial technology glass made of silica, quartz ring produced by high purity quartz sand manufacturers is a very good basic material. Quartz ring has a series of excellent physical chemical properties, such as:

1, high temperature resistance. Quartz glass softening point temperature of about 1730℃, can be used in 1100℃ for a long time, short time high use temperature up to 1450℃.

2, corrosion resistance. In addition to hydrofluoric acid, quartz glass almost no chemical reaction with other acids, its acid resistance is 30 times of ceramic, 150 times of stainless steel, especially in high temperature chemical stability, is unmatched by any other engineering materials.

3, good thermal stability. Adapt to the thermal expansion coefficient of glass is very small, can withstand drastic temperature changes, the quartz glass heated to 1100℃ so, put into normal temperature water will burst.

4, good light transmission. Quartz ring has good transmittance in the whole spectral band ultraviolet to infrared, the transmittance of visible light is more than 93%, especially in the ultraviolet spectral region, the larger transmittance can reach more than 80.
