Description
Wear resistant plastic castable is made by using ultra-high grade bauxite clinker as aggregate and powder, high-strength aluminosilicate cement as accelerator, along with additional sintering agents and inhibitors. It is formulated using our company’s patented product – a high-temperature adhesive as the binder. It can be used for repairing the inner lining of a circulating fluidized bed boiler or for overall construction of certain parts.
