Overhaul of Light Burned Magnesium Powder Protective Coating

The refractory materials used in heating furnaces in my country include general clay bricks, high alumina bricks, ramming materials, plastics, general castables and high-performance castings, high temperature resistant thermal insulation coatings, refractory cement, lightweight thermal insulation bricks, and heavy thermal insulation bricks. Insulation felt, aluminum silicate wool and other kiln refractory materials, these materials have high temperature resistance, but it is not easy to transform after high temperature oxidation conflict, requiring long shutdown of acid and alkali, and large loss of personnel during the construction period. At present, there are kiln lining maintenance coatings, which have high refractory temperature resistance and oxidative atmosphere. They are painted on the surface of various refractory materials to protect the formed refractory materials and avoid normal losses such as oxidative pulverization of refractory materials and conflict corrosion. , This is ZS-1022 kiln lining maintenance coating, a high-temperature energy-saving coating developed by the company for many years, ZS-1022 kiln lining maintenance coating, high temperature resistance, thermal shock resistance, high adhesion, good thermal insulation, anti- It has the characteristics of strong aging ability and convenient construction. It is directly sprayed on the surface of various materials lining the kiln, including thermal insulation bricks, castables, metals, ceramics, refractory fibers, quartz sand, silicon carbide, quartz glass, etc. Wear a layer of protective clothing on the lining of the furnace, which can well protect the lining material of the kiln, and lightly burn magnesia to form a layer of high temperature resistant and refractory dense integrated coating, which greatly extends the service time of the lining material of the kiln and reduces the kiln lining material. Damage rate of lining material. The kiln lining maintenance coating is made of a special high-temperature film-forming solution, which is polymerized at high speed after high-speed dispersion of high-temperature resistant inorganic materials such as ceramic oxides, silicon carbide, rare earth oxides, and ceramic fibers.
