High temperature surface coating High temperature surface coating is the surface coating of ceramic fiber stacked module, can also be used in the cracks and cracks of furnace wall refractories, with unique high heat insulation and low heat storage, at the same time can inhibit the shrinkage rate of ceramic fiber under high temperature, improve corrosion resistance, wear resistance, wind resistance. In addition, the combustion gas impure has excellent resistance, can provide two forms of dry and wet.
