2023-10-08In an electrolytic cell, the current flowing into the electrolyte from this point is called a graphite anode plate. In the electrolysis industry, the anode is generally made into a plate shape, so it is called a graphite anode plate. It is widely used in ferries, wastewater treatment, industrial anti-corrosion equipment, or as a special material.Compared with other materials, graphite anode plates have advantages such as high temperature resistance, good conductivity and thermal conductivity, easy mechanical processing, good chemical stability, acid and alkali corrosion resistance, and low ash content; Used for electrolyzing aqueous solutions, producing chlorine, caustic soda, and electrolyzing salt solutions to produce alkali; For example, graphite anode plates can be used as conductive anodes for electrolysis of salt solution to produce caustic soda. Graphite anode plates can be used as conductive anodes in the electroplating industry, making them an ideal material for various elect
2023-10-08Graphite materials are mainly composed of polycrystalline graphite and belong to inorganic non-metallic materials. However, they are called semi metals due to their excellent thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than certain metals, and also has a much lower coefficient of thermal expansion, high melting point, and chemical stability than metals. This makes it of great value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compoundsGraphite is another high-temperature resistant material that does not melt at high temperatures. It also has good thermal shock resistance and excellent self-lubricating propertiesThe disadvantage of graphite is its poor seismic performance. It begins to oxidize at 500 ℃ in the atmosphere, and the oxidation rate increases with the increase of temperature
2023-09-25The load migration rate of graphene at room temperature is about 15000cm2/(v · s). This value exceeds 10 times the silicon material. More than twice. Under certain conditions such as low temperature, the load migration rate of graphene can even be as high as 250000cm2/(v · s). Unlike many materials, the electronic migration rate of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electronic migration rate of a single laye
2023-09-25The effect of expanding graphite on water pollution has a large number of research results. In terms of governing oil and organic pollution in the control of water bodies, expansion graphite is far more effective and economical than ordinary activated carbon now. But expansion graphite is inconvenient to transport and needs to be prepared at the application site. The preparation, use, recycling, and regeneration of expansion graphite environmental protection materia

The first is the transformation of old technical equipment; the second is the current hot technical products of the development of charcoal graphite materials, such as the negative materials of lithium -ion batteries, the industrialization and intensiveization of the same -sex graphite, hig
2023-09-18Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce
