The foundry industry in the machinery industry uses graphite material as the pressure casting, centrifugal casting, super hard alloy hot extrusion and other processing of the mold, big to the train wheel, small to precision parts can be used graphite mold. Graphite mold can be used repeatedly, after the release of the casting has a high degree of finish, some without further processing can be used. Graphite materials used in the casting mold should be of high quality, low thermal expansion coefficient and good oxidation resistance. Graphite can be used in the casting of large size. China for the manufacture of a large number of graphite mold, in 2005, the continuous casting of graphite about 1500t, the use of graphite…
The graphite material plate has a good electrical conductivity,thermal conductivity,and corrosion resistance,so it’s widely used as the bipolar plate of full cell. However,there are some small hole,during the production process,and the size of the holes are different. The main reason is that some coal tar which is used as binder will be oxidation or volatilization during the making process. And this situation will have a bad influence on the graphite plate The porosity of graphite plate is about 18.2%~24.4%. Now,the most common method is using some organic compound to fill in the hole of graphite plate,such as phenolic resin, paraffin, asphalt, polymer, etc. to achieve the purpose of sealing,but it can increase the resistance of graphite plate. The new way…
Forging graphite emulsion (forging demoulding agent) is a compounded with graphite and other polymer materials of water-based release agent, is black, non-ferrous metal hot and cold working mould release lubricant. Forged sub micron graphite emulsion is a high-end products in the forging of graphite, metal precision forging, when its very fine graphite particles attached to the surface of the mold, can form a layer of thin film solid adhesion on metal mold surface, this film has excellent lubrication, high temperature resistance. The product is mainly used for forging forging, metal mold machining, heat extrusion processing (such as aluminum, copper and other non-ferrous metals), molten steel casting, pure silicon smelting and other fields. Main ingredients Graphite, inorganic film forming material, organic…
