Speaking of graphite products, we are not unfamiliar with them. As the name implies, they are graphite products made of graphite materials. However, many people do not know what graphite products are used for? In fact, everyone has used it, but they haven't paid attention to it. First of all, I'd like to tell you that the pencil lead used for reading in the past belongs to graphite products, which may just be inconspicuous. When it comes to the wide application of graphite products, Xiaobian should first start with the characteristics of graphite. We should all know that graphite has high temperature resistance, strong conductivity, acid and alkali resistance, corrosion resistance, wear resistance, lubrication and other characteristics. Through these characteristics, it is not difficult for us to understand what graphite products are used for. We briefly summarize the uses of four kinds of graphite products for your reference:
1、 Graphite products - graphite crucible
Life has come into contact with many metals, such as gold, silver and copper. How did these metal handicrafts come from? In fact, the very simple first step is to melt these metals before casting. In this way, a container is indispensable, and a material with high temperature resistance and high melting point is just needed. In this way, graphite crucibles on the market appeared. Because the melting point of graphite crucibles can reach more than 3000 degrees, and they are corrosion-resistant and oxidation-resistant, they are most suitable. Therefore, there are often types of graphite crucibles for melting aluminum and silver.

2、 Graphite products - graphite mould
As mentioned above, crafts that need to be poured need molds as casting and pressing molds. At this time, only graphite molds can withstand high temperature, high melting point, oxidation resistance and corrosion resistance. Hot bending graphite molds, electronic sintering graphite molds, and exothermic welding graphite molds are commonly used in the manufacturing industry.

3、 Graphite products - graphite plate
Graphite plate can also be used as graphite anode plate, which mainly uses the conductivity of graphite, because graphite plate is also used as the anode conductive material of salt solution electrolytic cell for producing caustic soda (sodium hydroxide) and chlorine gas, and the furnace head conductive material of resistance furnace for producing carborundum (silicon carbide). Carbon and graphite products are widely used as conductive materials in the electrode manufacturing industry as slip rings and brushes. In addition, they are also used as carbon plates in dry batteries, arc carbon rods for searchlights or arc generation, and anodes in mercury rectifiers.

Graphite rotor, as a kind of graphite products, mainly uses the wear resistance, lubrication and high temperature resistance of graphite. As a degasser rotor, it is often impossible to improve the wear resistance of sliding parts with lubricating oil under the conditions of high speed, high temperature and high pressure. As a graphite rotor, it can work without lubricating oil in a corrosive medium at a temperature of - 200 ℃ to 2000 ℃ and at a very high sliding speed (up to 100 m / s).

The above is just a brief introduction to the uses of several graphite productsGraphite productsWhat is it used for? In fact, there are too many. Xiaobian will not explain one by one. The application of graphite products is as wide as the atomic energy industry and military industry.
