CLAY AND HI-AL REFRACTORY PLASTIC MATER
CLAY AND HI-AL REFRACTORY PLASTIC MATERIAL
Refractory plastic material are composed bf basic raw material, such as, refractory aggregate, refractory fine power and plastic clay etc. and made by adding chemical binding agent and water and mixing and extruding. While supplying, the product is of mud Like or blank prepared, while being used. It needs to be pouned. This product has good features, such as, high strength at high temp. good stability of heat vibrating. Low coefficient of themal transmission etc. and good integrativity of kilns, and fumaces linings of heating fumace, even heating fumace, heat treatment fumace, boilers and other high temp, equipment, and also can be used as material to rapidly repair.
