Graphite 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.

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

The densification process of carbon graphite materials

With the continuous expansion of the application field of graphite materials, more and higher requirements have been put forward for it. Therefore, it is necessary to introduce new supplementary process methods in industrial production to facilitate the acquisition of products with special properties that cannot be obtained using ordinary methods. This process method is the compaction of carbon graphite materials.Carbon graphite material is a porous material, with a densification process that involves filling the pores or coating surface of carbon graphite material with different forms of carbon, metal, alloy, or other non-metallic substances. The purpose of densification process is mainly to improve the density, strength, conductivity, thermal conductivity, corrosion resistance, and wear resistance of the product, and sometimes to ensure that the product is impermeable to gases and liquids. However, there is a limit to compaction, and it is not possible to require all the pores in th

Several factors of hot pressure graphite mold damage

1. Broken: Graphite mold directly contacts the matrix powder containing diamond. The contact surface is in a high pressure state. The hardness of diamond and graphite mold is too poor. The surface of the mold that is in contact with diamond tool head will produce concave pits.Second, the type of damage: During the sintering process, the matrix powder infiltrates into the oxidation gap of the graphite mold under the melting state, resulting in the adhesion between the tool head and the mold, making it difficult for molding. The repeated attack of the mold can remove the mold, which causes the lack of edges and metal pit in the mold.Third, the wear size of graphite molds is very poor: some substrate powder will be squeezed out of the mold surface in the melting state to attach to the graphite material. Before using the mold next time, metal residues must be removed manually, which causes the shape and size of the mold to exceed the tolerance.Fourth, surface oxidation and cracking: Becau
