Coating classification: graphite crucible antioxidant coating

It is suggested that in high temperature environment, the problem of oxidation and corrosion of graphite materials should be solved, the service life of graphite materials should be increased, and the production efficiency should be improved Graphite crucible is widely used in smelting of alloy tool steel and smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical industry and other industrial sectors because of its high temperature resistance, small coefficient of thermal expansion, certain strain resistance against thermal shock, strong corrosion resistance to acid and alkaline solution, and excellent chemical corrosion resistance stability Economic effect Graphite crucible is mainly made of graphite, which is an allotrope of carbon Each carbon Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: in high temperature environment, solve the problem of graphite material oxidation corrosion, improve the service life of graphite material, improve production efficiency Graphite crucible, because of its high temperature resistance, small coefficient of thermal expansion, certain strain resistance against thermal shock, strong corrosion resistance to acid and alkaline solution, and excellent chemical corrosion resistance stability, is widely used in alloy tools in metallurgy, casting, machinery, chemical industry and other industrial sectors The smelting of steel and non-ferrous metals and their alloys has good technical and economic results Graphite crucible is mainly made of graphite, which is a kind of allotrope of carbon The periphery of each carbon atom is connected with another three carbon atoms (arranged in honeycomb like hexagon) to form covalent molecules by covalent bond Most of the graphite crucibles are carbon and some of them are air, so that the graphite crucibles are prone to oxidation, relaxation and falling off at high temperature Researchers of Beijing Zhisheng Weihua anti-oxidation coating have long found that graphite materials begin to oxidize at about 500 ℃ With the increase of graphite crucible temperature, the oxidation rate shows a geometric growth, and the oxidation is intensified There are three kinds of graphite materials under high temperature, including graphite electrode, graphite mold and graphite crucible Under high temperature, graphite is prone to oxidation and combustion reaction, resulting in the increase of porosity and structure porosity of carbon layer on the surface of the material, affecting the service life Taking the conventional baking of ladle as an example, the decarburized loose layer of more than 15mm is produced on the surface of carbon (graphite) refractories after baking, and the decarburized layer is quickly eroded after being filled with steel At this time, most of the graphite crucibles adopt zs-1021 high-temperature resistant sealing coating, which has high temperature resistance It adopts Zhisheng Weihua special high-temperature solution, and the temperature resistance can reach 1800 ℃, which can withstand open fire barbecue for a long time The coating material adopts nano scale structure, with good compactness, effectively preventing the diffusion of oxygen under high temperature, and the hardness can reach 7-8h, which is higher than the hardness of metal Zhisheng Weihua zs-1021 high temperature resistant sealing coating is applied on the graphite crucible to form a dense coating, which has strong anti rust and anti-corrosion, high temperature and anti-oxidation, anti discoloration, wear resistance and other characteristics High temperature resistant sealing coating is applied on kiln, graphite, metal, etc to prevent the oxidation rate under high temperature can reach more than 80%, and the energy-saving utilization rate of graphite crucible material can reach more than 95% The graphite electrode used in the high temperature oxidation environment will undergo partial sublimation oxidation due to the high temperature arc, which will cause the continuous consumption of the graphite crucible, even fracture and damage The loss rate of graphite crucible can reach 40-60% ZS high temperature resistant sealing coating researched and produced by Zhisheng Weihua for many years is mainly used for anti-oxidation protection of graphite electrode, graphite crucible and graphite parts under high temperature environment, delaying oxidation speed, increasing material strength and improving service life It effectively reduces the probability of fracture, breakage and falling off of graphite electrode After the graphite crucible is impregnated with anti-oxidation coating, its high temperature zs-1011 graphite transition coating liquid can penetrate into the pores of the graphite crucible, empty the residual air in the graphite crucible, and form an anti-oxidation protective film on the pores and the surface of the graphite crucible It is this protective film that can effectively insulate the air from direct contact with the graphite crucible and produce oxidation reaction The graphite crucible impregnated with the Zhisheng Weihua anti-oxidation coating will not crack and fall off in the high-temperature upheaval, so it can effectively delay the oxidation of the graphite crucible and extend the service life of the graphite crucible Technology first, graphite crucible anti-oxidation coating, water-based inorganic environmental protection coating, no volatile matter at high temperature and normal temperature Zs-1021 Weihua high temperature resistant sealing coating is acid and alkali resistant and does not react with quenching medium It can effectively protect the graphite crucible from chemical reaction at high temperature and effectively prevent the oxidation rate of the graphite crucible at high temperature from reaching more than 95% Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news
