Product Description:
Impermeable castable is the clay clinker as the main raw material, adding powder, binder and admixture configuration of the unshaped refractories, usually to cast the whole lining in the majority, can also be used according to the construction parts in the factory custom castable prefabricated pieces splicing.Working Principle:
Anti-seepage castable series products have high strength, low thermal conductivity, and strong resistance to penetration characteristics, prevent the liquid aluminum and the penetration of the electrolyte, erosion, so as to prolong the service life of electrolyzer, at the same time, to prevent the electrolyte in refractory insulating layer makes the coefficient of thermal conductivity increase in cell power consumption increasing, anti-seepage castable in use process can react with the alkali metal ions in the electrolyte, formation isolation membrane, so as to achieve the aim of seepage control.Application:
Impermeable castables are widely used in power stations, boilers, melting and casting furnaces, heating furnaces, soaking furnaces, heat treatment furnaces and induction furnaces and other lining different parts of the selection.|
