Heating furnace in our country with refractory materials are generally clay bricks, high alumina brick, ramming material, plastic, general castable and high-performance casting, high temperature resistant heat insulation coatings, refractory cement, lightweight insulation brick, heavy insulation brick, such as thermal insulation blanket, aluminum silicate cotton kiln refractory material, high temperature resistant, these data but not easy to reform after the high temperature oxidation loss of conflict, requirements boiler stop, acid-base long construction cycle personnel loss. Now have kiln lining maintenance coating, refractory high heat resistance, resistance to oxidizing atmosphere, besmear to brush in a variety of refractory materials on the surface, a good maintenance molding refractory material, to avoid oxidation of refractory material pulverization, conflict corrosion such as normal wear and tear, that is the ZS - 1022 kiln lining maintenance coating, ZS - 1022 kiln lining maintenance coating, high heat resistance, thermal shock, high adhesion, good heat insulation, strong anti-aging ability, construction is convenient wait for a characteristic, directly spray on various materials on the surface of furnace lining, insulating brick, castable, metals, ceramics, refractory fiber, quartz sand, silicon carbide, quartz glass, etc., Put on a layer of maintenance clothes for the lining of the kiln, maintain the lining data of the kiln well, and lightly burn magnesium oxide to form a layer of refractory compact and high-temperature integrated coating, which greatly extends the service time of the lining data of the kiln and reduces the damage rate of the lining data of the kiln. The kiln liner maintenance coating is made of special high temperature film solution made by Zhisheng Weihua, ceramic oxide, silicon carbide, rare earth oxide, ceramic fiber and other inorganic materials resistant to high temperature after high speed dispersion and polymerization.
