Standard brick is often used in circular kiln lining, u-shaped furnace door location, widely used in metallurgy, building materials, chemical industry, petroleum, machinery manufacturing and other industrial fields.\n The clay brick is made of 50 % soft clay and 50 % hard clay clinker, which is prepared according to the prescribed particle size requirements. after molding and drying, it is burned at a high temperature of 1300 ~ 1400 ℃.
The mineral composition of clay brick is mainly kaolinite ( Al2O3. 2SiO2. 2H2O ) and 6 % to 7 % of impurities ( oxides of potassium, sodium, calcium, titanium and iron ).\n Clay brick belongs to weak acid refractory products, which can resist the erosion of acid slag and acid gas, and has a slightly poor resistance to alkaline substances.
The thermal performance of clay brick is good, and it is resistant to urgent cold and heat.\n Product features:\n Durable, and fire prevention, heat insulation, sound insulation, moisture absorption, heat resistance, high strength, earthquake resistance, chemical erosion resistance and other characteristics!
