Refractory material has a great influence on the furnace type, the technical progress of refractory high purity magnesite and the performance and quality of refractory material not only affect the furnace type structure, but also affect the running status, maintenance times and service life of the furnace. Heating furnace in our country have common clay brick, high alumina refractory bricks, ramming material, plastic, the common castable and high-performance casting, high temperature resistant heat insulation coatings, refractory cement, lightweight insulation brick, heavy insulation brick, furnace refractory materials such as thermal insulation blanket, aluminum silicate cotton, the high temperature resistant material, but not easy to reform after the high temperature oxidation of friction loss, need to stop the furnace, acid-base long weeks of construction personnel loss. Now have a kiln lining protection paint, refractory high heat resistance, resistance to oxidizing atmosphere, besmear to brush in all kinds of refractory materials on the surface, is very good to protect the molding of refractory materials, prevent the oxidation of the refractory powder, friction corrosion and other normal wear and tear, that is the ZS - 1022 kiln lining protection coatings, high temperature energy saving coatings research and development for many years, the ZS - 1022 kiln lining protection coating, high heat resistance, thermal shock, high adhesion, good heat insulation, anti-aging ability, construction is convenient wait for a characteristic, spray directly on the furnace lining of various materials on the surface, Including insulation brick, castable, metals, ceramics, refractory fiber, quartz sand, silicon carbide, quartz glass, etc., put a layer of protection on kiln lining cloth, good protection of kiln lining materials, light burned magnesia to form a layer of high temperature resistant refractory coating, compact integration greatly prolong the life time of the furnace lining materials and reduce the damage rate of kiln lining materials.
