Płyty termoizolacyjne

Ceramic fibers are made of molten silicon and aluminum oxides in the process of spinning. This gives white, twisted fibers with high temperature resistance, low thermal conductivity and good chemical resistance. They have excellent resistance to sudden temperature fluctuations. Since it is not possible for the pure ceramic fiber to be processed into texile products, organic fibers must be added to allow the spinning. The organic content of these articles is about 15% (fired during the first heating, hence the inevitable losses of incandescence). In addition, textiles are reinforced with twine made of glass strand or wire of chrome steel. The maximum temperature resistance of the glass strand is about 550 °C, and goods made of chrome steel wire can be used up to 1000 ° C. Obviously, the impact of media and mechanical loads of material should be taken into consideration. Thermal resistance of devices without a core, such as wool, mats or paper is based on version: 1260 °C to 1430 °C for aluminosilicate fibers, or 1600 ° C for polycrystalline fibers (mullite and corundum). These products are resistant to water, oils, fats, liquid metals and most acids. The main characteristics of ceramic fiber textiles are: resistance to continuous heat load of up to 1600 °C, very good thermal insulation properties, low weight, flexibility, thermal shock resistance, excellent electrical insulating properties
