Graphite powder is a widely used industrial material, which is obtained from high-purity graphite after crushing, grinding, and screening. The classification of graphite powder is mainly based on the particle size, ranging from 50 mesh to 30000 mesh. The larger the mesh, the finer the particle size, and the higher the price.

In industrial production, graphite powder is used in many industrial fields, which is inseparable from the excellent performance of graphite powder. However, when graphite powder is used as industrial production raw materials such as graphite sealing products and graphitized electrodes, it is necessary to improve, change or increase the performance of graphite powder through certain methods. Graphite powder is an industrial raw material for graphite sealing products and graphitized electrodes. Graphite sealing products and graphitized electrodes are products with a high density of graphite powder.
Graphite powder impregnation is one of the methods. Graphite powder generally exists by directly applying it in the industry in powder form or in solid form. The physical form of graphite powder is soft. After graphite powder is processed into graphite products, it has the disadvantage of being hard and brittle, which will shorten the service life of graphite products. Only through a series of methods such as impregnation, Graphite powder impregnation is made some pregnant materials in liquid state penetrate into the pores of graphite products at a certain temperature and pressure, so as to improve the performance of graphite products.
However, the quality of graphite powder processed from graphite material is worse than that directly processed from natural graphite. Graphite material is indeed made of graphite powder. Before making graphite material, the purity of graphite powder is very high and the particles are very uniform. The graphite powder is bonded together through the adhesive and then extruded to form a graphite block and become graphite material. Subsequently, the usable graphite material is formed through impregnation baking.
Graphite powder is powder. The powder is composed of particles, coarse and fine. Some of the lubricating graphite powder we see is produced and processed from natural graphite, and some are the rest of the powder when we process graphite. Although both are graphite powder, they have different meanings. The graphite powder processed from natural graphite has purity and uniform particle size, The remaining graphite powder gas particles are relatively coarse when we process graphite, because it is the remaining graphite powder when processing graphite products, and the purity of graphite powder may not be high.
The graphite products impregnated with graphite powder can reduce the generation of pores in graphite powder products, overcome the shortcomings of hard and brittle graphite products, and increase the flexibility of graphite, which can not be achieved by previously non impregnated graphite products. The impregnated graphite powder can be processed into graphite sealing products such as graphite paper, graphite flexible packing ring, graphite sealing gasket and graphite packing, The purpose of graphite powder impregnation increases the new properties of graphite powder products and enables graphite powder products to be applied to more different industrial fields.
