Refractory materials for heating furnace in China include general clay brick, high alumina brick Ramming material , plastic, general castables and high-performance castables Light burned magnesium powder ， High temperature resistant thermal insulation coating, refractory cement, light insulating brick, heavy insulating brick, insulating felt, aluminum silicate wool and other kiln refractory materials have high temperature resistance, but it is not easy to transform after high temperature oxidation conflict loss, which requires long acid and alkali shutdown, and large personnel loss during the construction period. Now there is a furnace lining maintenance coating, which is fire-resistant, high temperature resistant, and oxidation resistant. It is painted on the surface of various fire-resistant materials, which can well maintain the molded fire-resistant materials and avoid normal loss of fire-resistant materials such as oxidation, pulverization, conflict corrosion, etc. This is ZS-1022 furnace lining maintenance coating, a high-temperature energy-saving coating developed by Zhisheng Weihua Company for many years, ZS-1022 kiln lining maintenance coating is characterized by high temperature resistance, thermal shock resistance, high adhesion, good thermal insulation, strong anti-aging ability, and convenient construction. It is directly sprayed on various data surfaces of the kiln lining, including insulation bricks, castables, metals, ceramics, refractory fibers, quartz sand, silicon carbide, quartz glass, etc., to put a layer of maintenance clothes on the kiln lining, Good maintenance of kiln lining data, light burning magnesite forms a layer of high temperature resistant, fire-resistant and compact integrated coating, greatly extending the service time of kiln lining data and reducing the damage rate of kiln lining data. The kiln lining maintenance coating is made of Zhisheng Weihua's special high-temperature film-forming solution, ceramic oxide, silicon carbide, rare earth oxide, ceramic fiber and other high-temperature resistant inorganic materials after high-speed dispersion and polymerization.
