The traditional refractory slurry only fills the brick joint between the refractory brick and the brick, so the brick joint does not have the overall structural strength, the refractory mud in the middle of the brick joint is loose, and the corrosion resistance is lower than that of the refractory brick product. The clay, high-aluminum and corundum phosphate refractory mud produced by the company is made of high-quality refractory bone powder as the main raw material and polyphosphate as a binder, plus various additives. It changes this phenomenon, so that the brick masonry can form a whole at high temperature and has high strength, and the refractory mud has good construction performance, no precipitation, no flow, short sleep time, small shrinkage after high temperature burning. , anti-slag, anti-scouring ability.
