High temperature quartz glass

Specific sizes and technical requirements determined by the customer, we guarantee the quality of products quartz plates:! Different geometric surface shape (the maximum size) Square: 700X700 Thickness: 2 ~ 10mm rectangular: 300mm within X2000mm thickness: 2 ~ 15mm round: The maximum thickness of 4 or more in diameter 500mmX quartz glass is silica glass manufacturing special industrial technology, is a very good base material. Quartz glass has a series of excellent physical and chemical properties. Such as: 1, high temperature. Quartz glass softening temperature of about 1730 ℃, long-term use at 1100 ℃, short-term maximum temperature up to 1450 ℃. 2, corrosion-resistant. In addition to hydrofluoric acid, quartz glass hardly react with other acids, the acid resistance of stainless steel is 30 times 150 times ceramics. Especially in the chemical stability at high temperatures, it is any other engineering materials can not match. 3, good thermal stability. Thermal expansion coefficient of quartz glass is extremely small, it can withstand severe temperature changes, quartz glass is heated to about 1100 ℃, into the water at room temperature will not burst. 4, good light transmission. Quartz glass in the ultraviolet to the infrared spectral bands in the whole has a better light transmittance, visible light transmittance of 93% or more, particularly in the UV spectral region, the maximum transmission rate of up to 80%. 5, good electrical insulation properties. The resistance of quartz glass is equivalent to one million times that of ordinary glass, is an excellent electrical insulating materials, even at high temperatures also have good electrical properties. With the above quartz glass excellent physical and chemical properties, it is widely used in point source, semiconductors, optical communications, military, building materials, chemical, machinery, electricity, environmental protection and other fields. Caution: 1, quartz glass products is a valuable material, must be handled with care when using, be very careful; 2, various quartz glass has a maximum operating temperature, the use should not exceed this temperature, otherwise it will Crystallization or softening deformation; 3, quartz glass require high temperatures must be wiped clean before use. You can use 10% of hydrofluoric acid or lotion soak, then wash with high water or alcohol treatment. Operation should wear thin gloves, not allowed to touch the quartz glass with bare hands; 4, allowing for continuous use at high temperature quartz glass, quartz glass which is to extend the life and improve the heat resistance is good. Conversely, the high temperature intermittent use quartz glass, frequency of use is limited; 5, although quartz glass with high thermal stability, can withstand severe sudden changes in temperature difference. But the actual use, due to the different shape of the product residual strain and thermal stability have some differences, should be paid attention; 6, quartz glass-based acidic material, strictly avoid with alkaline material (such as water glass, asbestos use at high temperatures, potassium and sodium compounds, etc.) contact, otherwise it will greatly reduce the anti-crystallization properties.
