Types, properties, and uses of mechanical carbon graphite products

Mechanical carbon graphite products are carbon graphite materials used as structural components in various machinery, including various graphite bearings, graphite sealing rings, graphite piston rings, graphite sliding plates, and graphite brake friction plates.According to different production processes, mechanical carbon graphite products are mainly divided into 7 categories: (1) carbon graphite; (2) Electrochemical graphite; (3) Resin impregnated carbon and electrochemical graphite; (4) Carbon and electrical graphite impregnated with metal; (5) Carbon graphite material with resin as binder; (6) Metal - graphite material; (7) Flexible graphite material.Mechanical carbon graphite products can work in corrosive media within the temperature range of -200~2000 ℃ and operate normally without lubricating oil at high motion rates. They have self-lubrication, good wear reduction performance, high thermal conductivity and heat shock resistance, low linear expansion coefficient, and good mech

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.

Classification of Graphene

There are two classification methods for graphene. One is based on the number of layers, which can be divided into four categories: single-layer, double-layer, few layer, and multi-layer products; Another type of product can be divided into three categories according to its form: powder, slurry, and film. Graphene powder and graphene thin film are currently the two main forms of graphene materials. The former is mostly doped in other materials and is widely used in coatings and lithium-ion batteries; Graphene thin films are widely used in the fields of electronics, photons, and optoelectronic devices due to their advantages of transparency, conductivity, and flexibility. Different graphene products have certain differences in raw materials due to different preparation methods. Graphene powder is mainly formed by physical or chemical methods, and the main raw material is natural graphite. Graphene thin films are mainly deposited by chemical vapor deposition, and their raw materials are

Application of flake graphite in the coating industry

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings.As a anti-corrosion material, it is made with carbon black, talc powder, and oil as an anti rust primer, which has good resistance to chemical and solvent corrosion. If chemical pigments such as zinc yellow are added to the formula, its anti rust effect is better.The expandable graphite used as a fireproof filler is a graphite interlayer compound obtained from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the expandable graphite rapidly expands in volume (up to 300 times), suffocating the flame and generating an expanding substance to isolate the flame, delay or interrupt the flame spread. It is also non combustible, has good softness, and has high surface energy, The carbonization layer has good strength. However, the volume and dosage of the expansion body should be selected appropriately. Exper
