Description of Refractory plastic
Wearing resistant refractory plastic is bulk refractory, its main raw materials are calcined refractory aggregate, fireclay, and other binders, they are mixed and tempered to plastic bodies.During construction, pneumatic hammer or manual hammer can be used to ram it into any shapes and thickness.
According to the types of refractory aggregates, they can be divided into clay, high alumina, mullite, corundum, chromium, silicon carbide, and zirconium containing refractory plastics. According to the type of binder, it can be divided into refractory plastic materials such as aluminum sulfate, phosphoric acid, phosphate, water glass, and resin.
Advantages of Refractory Plastic
1.Good Plasticity;
2.Good Slag Resistance;
3.Good Corrosion Resistance;
4.High Strength And High Density;
