Micro expansion Wear-Resistant Refractory Plastic for Circulating Fluidized Bed Boiler
The Description:
Wear-resistant refractory plastic composition: wear-resistant refractory plastic is composed of refractory aggregate, powder, binder and plasticizer, of which refractory aggregate according to the material is divided into: clay clinker, high aluminum clinker, corundum aggregate; The bonding agents are clay bonding, water glass bonding, phosphoric acid or aluminum phosphate bonding, aluminum sulfate bonding, etc. According to the working environment of the kiln and the parts used, the raw materials of the corresponding materials are selected and configured.
