The characteristics of alumina wear-resistant ceramic tiles
Wear-resistant ceramic tiles are special corundum ceramics made of Al2O3 as the main raw material, rare metal oxides as the flux, and fired at a high temperature of 1,700 degrees. Wear-resistant ceramic sheets have various specifications, shapes and sizes, and generally have several aluminum contents of 92%, 95%, 96%, and 99%. Ceramic mosaics, small discs, square tiles, etc. are bonded and combined into wear-resistant ceramic sheets. Ceramic patch can be used as anti-wear material on equipment.
Its wear resistance is 266 times that of manganese steel and 171.5 times that of high chromium cast iron. Far exceeds the wear resistance of wear-resistant steel and stainless steel. Alumina ceramics have stable chemical properties, excellent corrosion resistance, and can withstand corrosive substances such as concentrated sulfuric acid and hydrochloric acid. Not only that, wear-resistant ceramics can also operate in a high temperature environment of more than 1,000 degrees.
Alumina wear-resistant ceramic tiles can be widely used in pulverized coal conveying systems in power plants, dust removal equipment in steel plants, and hopper hopper equipment in cement plants. If the working conditions require higher wear resistance, a wear-resistant ceramic liner can be used. The thickness of the liner can better resist the wear of materials. At different temperatures, use different heat-resistant glues together to avoid the phenomenon of ceramic shedding under the condition of rising temperature.
