Graphite electrode, high temperature resistant oxidation coating, formulation technology
Graphite crucible through anti-oxidation coating impregnation besmear after treatment, the ZS-1011 high temperature graphite coating liquid can penetrate into the pores of graphite crucible, the residual air emptying graphite crucible, forming a layer of antioxidant protective film on the graphite crucible and graphite crucible surface porosity. It is this layer of protective film can effectively isolate the air in direct contact with the graphite crucible and graphite crucible by reaction of the Chi Sheng Wei Hua coating impregnation treatment, no cracking, shedding in high temperature changes, which can effectively retard the oxidation of graphite crucible, prolong the service life of the graphite crucible.
In the high temperature induction heating graphite crucible, graphite electrode used in high temperature oxidation environment will occur due to the high temperature arc part sublimation oxidation, will cause the continuous consumption of graphite crucible, even broken, broken. The graphite crucible loss rate will reach 40-60%. Zhi Sheng years of research production Wei Hua ZS high-temperature sealing paint is mainly used in high temperature environment protection against oxidation of graphite electrode, graphite crucible, graphite products, slow oxidation rate, increase the strength of the material, improve the service life. The fracture rate of graphite electrode is lower than that of graphite electrode.
Graphite materials synthetic materials under high temperature including graphite electrode, graphite mold and graphite crucible three, these three kinds of materials of graphite under high temperature, the graphite is prone to oxidation combustion reaction, cause the rubber surface material of carbon layer porosity increase and loose structure, influence the service life. Taking the conventional baking process of the ladle as an example, the surface of the carbon containing (graphite) refractory material is produced more than 15mm after being roasted, and the decarburization layer is eroded rapidly after being filled. The majority of graphite crucible using ZS-1021 high temperature resistant sealing coating, the coating with high temperature resistance, Sheng Chi Wei Hua special high temperature solution, temperature can reach 1800 DEG C, can long time open flame barbecue, coating materials with nano scale lamellar structure, good compactness, effectively prevent the diffusion of oxygen at high temperature, the hardness can reach 7-8H and the hardness is higher than the hardness of metals. Zhi Sheng Wei Hua ZS-1021 high temperature resistant coating paint closed dense coating formed on the graphite crucible, with strong anti corrosion resistance, high temperature oxidation, anti discoloration effect, resistant properties. High temperature resistant sealing coating is applied to kiln, graphite, metal and so on. At the high temperature, the oxidation rate can reach more than 80%, and the energy saving efficiency of graphite crucible material can reach more than 95%.
Technology first, graphite crucible, anti-oxidation coating, water inorganic environmental protection paint, no volatile substance at high temperature and normal temperature. ZS-1021 Weihuanai closed high temperature coating itself with acid and alkali, the quenching medium of any reaction, chemical reaction can effectively protect the graphite crucible under high temperature, can effectively prevent the graphite crucible in high temperature oxidation rate reached more than 95%.
