, painted on the surface of graphite and other materials, forming a dense coating, to prevent oxygen and other oxidation atmosphere penetration, to protect graphite from oxidation. Graphite high temperature antioxidant coating paint on the paper, paper fire is not flammable. Graphite high temperature anti-oxidation coating, high temperature oxidation resistant coatings, Zhisheng Weihua company after years of research and development, ZS graphite high temperature anti-oxidation coating temperature resistance is divided into 150 degrees C, 600 degrees C, 800 degrees C, 1200 Different varieties of models, different types of coatings, different temperature resistance, high anti-oxygen diffusion, effectively improve the anti-corrosion capacity of the material, improve the life of the material, improve economic value. The application of ZS Zhisheng graphite high temperature anti-oxidation coating applied to high temperature kiln reframe material shows that the high temperature anti-oxidation coating of Zhisheng Weihua graphite can reduce the pore rate of aluminum magnesium carbon brick, improve the antioxidant capacity of aluminum magnesium carbon brick and the pressure strength after burning, and improve the high temperature load softening deformation temperature of aluminum magnesium brick.
graphite at high temperatures includes graphite electrodes, graphite molds and graphite crucibles, the graphite in these three materials at high temperatures, graphite is prone to oxidation combustion reaction, resulting in the surface of the material plastic carbon layer pore rate increased and structural loosening, affecting the service life. Take the conventional baking of steel bags as an example, carbon -containing (graphite) refractory material after baking the general surface produces more than 15mm of decarbonization loose layer, decarbonization layer in the steel quickly eroded. The graphite electrode loss of the steel mill accounts for more than one-tenth of the production cost of the steel mill, in Zhisheng Weihua high temperature oxidation laboratory saw that a 3 kg of graphite crucible at a high temperature of 1600 degrees C lasted 3 hours, the weight of more than 30%, that is, 3 kg of graphite crucible became 2 kg, oxidation really fast. Graphite is a relatively valuable material, corrosion oxidation caused by increased production costs, waste of energy materials.
the oxidation of graphite electrode mainly occurs in its sidewall, according to the carbon material oxidation theory, graphite electrode oxidation reaction is divided into three different temperature zones. The first and second reaction temperature zones are about 500 to 1000 degrees C, called low-temperature oxidation zone, graphite electrode loss accounts for less than 2% of the total consumption, 1000 degrees C or more for the third reaction temperature zone, called high-temperature oxidation zone, high-temperature oxidation loss is 20 to 50 times the low-temperature oxidation loss. Therefore, to prevent graphite electrode oxidation loss should mainly study the high temperature oxidation area. ZS-1021 graphite high temperature antioxidant coating is developed by Beijing Zhisheng Weihua Chemical Co., Ltd. based on the above theory for graphite oxidation loss development of professional energy-saving coatings. ZS-1021 graphite high temperature antioxidant coating high temperature resistance, the use of Beijing Zhisheng Weihua special high temperature solution, temperature resistance can reach 2600 degrees C, can be long-term open fire fire-resistant barbecue, materials using nano-ceramic fish scale structure, in the high temperature process melting sintered network glass phase state, good denseness, in the surface of the material oxidation decarbonization layer, to prevent gas and material contact, hardness can reach 7-8, has a good resistance to shock. ZS-1021 Zhisheng high temperature closed coating itself acid-resistant alkali resistance, high temperature, room temperature without any volatile substances produced, inororable water-based environmental protection, and quenching media do not have any reaction, can effectively protect the material at high temperature chemical reaction oxidation, can effectively prevent graphite electrodes, graphite crucibles, graphite rods and other high temperature oxidation rate of more than 96%.
