Anti-high temperature aluminum liquid corrosion coating heat and corrosion resistance
[Chinese aluminum industry network] Aluminum water is commonly known as liquid aluminum, its composition is simple aluminum, pure material, is liquid aluminum, aluminum melting point is 1535 degrees fast heat absorption slow material. Zhisheng Weihua high-temperature coating expert pointed out that aluminum water at high temperature will dissolve the refractory material, causing oxidation and chalking of the refractory material, and the phenomenon of material shedding and so on. This will have a great impact on the linked production and energy conservation.
Dissolving refers to the process of chemical reaction of a liquid with a solid/liquid/gas to make it a homogeneous phase in the molecular state called dissolution. The process in which a substance (solute) is dispersed in another substance (solvent) as a solution. High-temperature oxidation is one of the main reasons for the loss of quality in hot working of steel products. This oxidation phenomenon also has many unfortunable effects on the manufacturing process of steel products, such as low product yield, increased energy consumption per unit steel production, and increased production costs. In severe cases, it will also affect normal process operations in the production process, affecting the product's final quality and even causing accidents. Therefore, it is necessary to take measures to prevent or reduce the loss of steel and aluminum due to high temperature oxidation. Zhisheng Weihua's high-temperature anti-oxidation sealer coating protection technology is one of the effective methods to solve this problem.
Because the alloy steel hot processing temperature is high, usually requires 1000 °C for heating, and related products on the market, about 1000 °C anti-oxidation performance is often difficult to achieve thermal processing quality requirements. In order to solve this problem, Beijing Zhisheng Weihua Chemical Co., Ltd. ZS-1021 high temperature sealing coating, can fully meet the above indicators aluminum liquid anti-corrosion and oxidation requirements. 1021 High Temperature Sealing Coating High temperature resistance, using Beijing Zhisheng Weihua special high-temperature special solution, temperature can reach 2300 °C, can be fire-resistant barbecue for a long time, the material adopts nano-ceramic scaly structure, and the network glass phase state is sintered at high temperature. The compactness is good. The decarburization layer is oxidized on the metal surface to prevent the molten aluminum from contacting the refractory material. The hardness can reach 7-8H and it has good impact resistance. ZS-1021 high temperature resistant coating coating itself is acid and alkali resistant, no volatile substances are produced under high temperature and normal temperature, inorganic water environment protection, no reaction with quenching media, can effectively protect metal from chemical reaction under high temperature, and can effectively prevent fire resistance Material metal high-temperature oxidation rate of 95% or more. ZS-1021 high temperature sealed anti-oxidation coating has obvious anti-oxidation effect, which can reduce the original 5% oxide scale generated by ordinary hot rolled plate to 0.5%, and reduce the 3% oxide scale produced by stainless steel hot rolled plate. 0.2% or less. Zhisheng Weihua Chemical Co., Ltd. develops and produces this high-temperature protective coating, which fully meets the needs of the market.
Aluminum liquid high-temperature anti-oxidation anti-corrosion coating can effectively reduce high-oxygen rot. Compared with vacuum protection technology and inert gas protection technology, ZS-1021 high-temperature sealing coating has the characteristics of simple process, significant protection effect and low cost, and anti-oxidation coating is economical. The construction is of great significance. The coating has also been listed as one of the key energy-saving materials promoted and used by the National Energy Conservation Association.
Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. It is also resistant to thermal shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is precisely because of the excellent properties of Si3N4 ceramics that it is often used to make bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the Silicon Nitride Ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of engine parts, not only can the diesel engine quality be improved, fuel can be saved, but thermal efficiency can be improved.
