Product introduction of ceramic fiber cotton
Ceramic fiber is a kind of efficient insulation material, ceramic fiber cotton is the high purity clay clinker, aluminum oxide powder, silica powder, chromite sand and other raw materials in the industrial furnace at high temperature melting, the formation of fluid. Then the compressed air is blown or the spinning machine is used to spin the silk into fiber, and the cotton is collected by the cotton collector to form ceramic fiber cotton.
Features of ceramic fiber cotton
Ceramic fiber cotton has the characteristics of light weight, high strength, oxidation resistance, low thermal conductivity, good softness, corrosion resistance, small heat capacity and sound insulation.
