Graphite plates are often used in refractory materials, conductive materials, smelting furnace support plates, electrolytic plates, etc. The following editor will introduce to you what is graphite plate. The use of graphite plate, the processing technology of graphite plate, which graphite plate manufacturer is good?
1. What is a graphite plate?
Graphite plate is a conductive, high temperature resistant, corrosion resistant, and easy to process material. Widely used in metallurgy, electrochemistry, chemical industry, and other industries. Graphite plates include high-purity graphite plates, electrode graphite plates, and flexible graphite plates.
The specific characteristics of graphite plates are as follows:
1. High-temperature resistance. Graphite is one of the highest temperature-resistant materials known. The melting point is 3850℃±50℃, and the boiling point is 4250℃. Under the ultra-high temperature arc at 7000°C for 10 seconds, the loss of graphite is the smallest, and the loss of graphite is 0.8% by weight. It can be seen that the high-temperature resistance of graphite plates is very outstanding.
2. Special thermal shock resistance. Graphite has good thermal shock resistance, that is, when the temperature changes suddenly, the thermal expansion coefficient is small, so it has good thermal stability, and no cracks will occur when the temperature changes sharply.
3. Thermal conductivity and electrical conductivity, graphite has good thermal conductivity and electrical conductivity. Compared with general materials, it's thermal conductivity and electrical conductivity are quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel, and 100 times higher than ordinary non-metals.
4. Lubricity. The lubricity of graphite is similar to that of molybdenum disulfide, and the friction coefficient is less than 0.1. Its lubricity varies with scale size. The larger the scales, the smaller the coefficient of friction and the better the lubricity.
5. Chemical stability, graphite plate has good chemical stability at room temperature and can resist acid, alkali, and organic solvent corrosion.
Second, the use of graphite plate
There are many kinds of graphite plate products, such as high-voltage graphite plates, conductive graphite plates, refractory graphite plates, battery graphite plates, melting furnace trays, electrolytic plates, solar photovoltaic plates, etc., which are widely used. Usually divided into the following two categories according to characteristics:
1. Graphite plates with a density of 1.72g/cm3 are mainly used for solar photovoltaic panels, electrolytic panels, furnace trays, etc.
2. Bipolar plate, through impregnation treatment (generally impregnated with furan resin), greatly improves the impermeability of the product, and the product does not leak after impregnation, so it is widely used in the battery industry, and the product density can reach 2.0 -2.2g/cm3, the working temperature cannot exceed 200°C; the impregnation reagent is usually furan resin, phenolic resin, and metal, and the specific impregnation metal can be customized.
3. Processing technology of graphite plate
Graphite products, including graphite plates, graphite electrodes, graphite rods, and graphene, must go through the following production processes:
4. Which graphite plate manufacturer is better?
There are already many graphite sheet manufacturers in the market. These manufacturers established the graphite sheet industry. Graphite plate manufacturers can generally produce the following graphite products, such as graphite plates, graphite blocks, graphite rods, graphite bearings, graphite, high-purity graphite, fine-grained graphite, EDM electrodes, etc. The largest use of graphite plates is in the semiconductor field. However, it is also widely used in solar cells, sensors, nanoelectronics, high-performance nanoelectronic devices, composite materials, and field emission materials.
Manufacturers who choose graphite plates must shop around to ensure that they can buy the best quality products; what they can get is first-hand information, and there will be no special problems. No matter what kind of product it is, no matter which product manufacturer it is, don't pay attention to only comparing prices! This is very unwise. If the quality of the graphite plate is poor, it may not be able to meet the production needs. For more graphite board issues, please pay attention to Wikipedia, piracy must be investigated.
