Description
Product Description:Quartz windows are special industrial technical glass made of silica, which is a very good basic material. Quartz glass sheet has a series of excellent physical and chemical properties.
Product Features:
1. High temperature resistance. The softening point temperature of quartz glass is about 1730 °C, which can be used at 1100 °C for a long time, and the temperature can reach 1450 °C in a short time.
2. Corrosion resistance, quartz glass hardly reacts with other acid substances, its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially its chemical stability at high temperature is unmatched by any other engineering materials of.
3. Good thermal stability. The thermal expansion coefficient of the adaptable glass is extremely small, and it can withstand severe temperature changes. It will not burst when the quartz glass is heated to about 1100 ° C and placed in normal temperature water.
4. Good light transmission performance. Quartz glass sheets have good light transmittance in the entire spectral band from ultraviolet to infrared, and the transmittance of visible light is above 93%, especially in the ultraviolet spectral region, the transmittance can reach above 80.
5. Quartz glass has good electrical insulation properties. The resistance value of quartz glass is equivalent to 100 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at room temperature.
Product advantages:
The optical properties of quartz windows are unique, and their silica content can reach more than 99.99%. The hardness is Morse 7, and it has the characteristics of high temperature resistance, low thermal expansion coefficient, thermal shock resistance and good electrical insulation performance. The visible light transmittance of quartz windows is more than 85%. Quartz glass can be divided into two categories: fused silica glass and synthetic quartz glass. Heat resistance, light transmittance, electrical insulation, and chemical stability are all very good.
