The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.
The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:
First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heated to 100t before loading the product), and then the closed tank lid is tight.
Gradually packaged in vacuum, the negative pressure in the tank should be less than 79,800 Pa, and the time of vacuum packaging is 30 to an hour. After the vacuum packaging is terminated, put it into the asphalt glue that has been warmed to MORISOT (sometimes add a small amount of adding a small amount to the asphalt cement The coal coke or oil oil is reduced to the softening point of Liqing to 50, especially the level of the upper and lower H clearing liquid levels above 160 • mm higher than the top of the product. Then use air to compress the Liqing solution level.
2023-12-12There are weak van der Waals forces between layers in the structure of graphite, and these interactions are disrupted under high temperature conditions, leading to interlayer detachment of graphite.
The development of graphite mineral resources is of great significance for promoting economic and social development. However, how to achieve the balance of environmental protection in the development process is an urgent problem to be solved.
Graphite molds should be produced and processed by cutting methods to improve the smoothness of the graphite mold surface and reduce the degree of adhesion between the molten metal and high-purity graphite. The composition of the carcass powder is one of the factors that cause the metal plastic film to stick to the high-purity graphite. Because iron is a strong carburizing agent, if the carcass is iron-based, there will be obvious reaction and melting between the carcass and the abrasive tool, causing the carcass melt to stick to the high-purity graphite and destroying the graphite mold. It is suggested that when calcining the iron-based carcass, a strong release agent should be brushed on the surface of the blade and the abrasive tool to reduce the adhesion of the abrasive tool during mold unloading, reduce the degree of damage, and increase the service life of the abrasive tool.2. The fracturing damage of the grinding tool is also related to the resistance of the graphite materia2024-03-19The balance of graphite mineral exploitation and environmental protection
