Wearing resistant plastic refractories high alumina bauxite plastic refractory for heating furnaces
Refractory plastic is made of 70% - 80% granular and powder materials, 10% - 25% plastic clay and other adhesives, and an appropriate amount of plasticizer. It is an amorphous refractory material, mainly used for lining construction and repair of kilns. The fire resistance can reach 1750~1850 ºC
According to the type of refractory aggregate, it can be divided into clay, high alumina, mullite, corundum, chromium, silicon carbide, and zirconium containing refractory plastic materials. According to the type of bonding agent, it can be divided into aluminum sulfate, phosphoric acid, phosphate, water glass, resin, and other refractory plastic materials.
