Features
1. High temperature resistance: the softening point temperature of silica glass is about 1730 ° C, which can be used at 1180 ° C for a long time, and the maximum use temperature for a short time can reach 1450 ° C.
2. Mechanical properties: The mechanical properties of silica glass are better than those of glass and ceramics, several main indicators density 2.2g/cm3, elastic modulus 700*103kg/cm3, tensile strength -500kg/cm3, Lysohardness 5.5-6.5, and the strength reaches the maximum at the annealing temperature of 1180℃, which is a major characteristic of silica glass.
3. Thermal performance: 5.4*10-7, because the thermal expansion coefficient of silica glass is very small, equivalent to 1/12-1/20 of ordinary glass, the average expansion number of 0-1000℃ is the thermal expansion coefficient is very small, so it can withstand the temperature difference of cold and heat is very strong, generally can withstand the cold and heat test of 1200-15℃.
4. Silica glass is a good acid-resistant material, in addition to hydrofluoric acid and 300 degrees of hot phosphoric acid, at high temperatures, it can resist nitric acid, aqua aqua, neutral salts, carbon and sulfur erosion, its chemical stability is equivalent to acid-resistant ceramics 30 times, equivalent to nickelchromium alloy and ceramics. White rust steel 150 times, it is resistant to high temperature, heat shock, thermal expansion coefficient is particularly small, especially at high temperature chemical stability. It is incomparable to any other material.
5. The electrical insulation performance of silica glass is excellent, at room temperature, its resistance is equivalent to 100 times that of ordinary glass, the dielectric loss of all frequencies is very small, and the insulation compressive strength is large. Its silica glass is an excellent insulating material.
6. Optical performance: silica glass tubes have good transmittance in the entire spectral band from ultraviolet to infrared, and the transmittance of visible light is more than 95%, especially in the ultraviolet spectral region, the maximum transmittance
Applications
Used to make optical fiber, precision optical instruments, electronic components of the carrier, can produce quartz glass, steel factory production special.
Storage Conditions
Store in a cool, dry room and avoid heavy pressure. The powder without surface treatment should not be exposed to the air during use, so as to avoid hygroscopic agglomeration, affecting the dispersion performance and use effect.
