Graphite powder of brake pad production material, does brake pad production use artificial graphite?

Automobile brakes are a very important part of the car, and the material of the brake pads in the braking system is very important. There are many types of materials needed to make brake pads. What are brake pads?

What materials are available for brake pads? The following is an introduction to the graphite powder of the brake pad production material.

Ultra-fine graphite powder is ultra-fine particle size of graphite powder, ultra-fine graphite powder has a large number of meshes and small particle size, ultra-fine graphite powder has good lubricating properties, electrical conductivity, high temperature resistance, etc., ultra-fine graphite powder is used in various fields of industrial production, and the special graphite powder for brake pads is a kind of ultra-fine graphite powder, which can prepare various brake pads and other parts.

Ultra-fine graphite powder is used in the production of brake pads, brake pad special graphite powder is one of the materials for manufacturing brake pads, brake pad special graphite powder plasticity is very good, can be combined with resin, rubber, reinforcing fiber and other materials, it is made of brake pads, brake pads special graphite powder can play a role in wear resistance, high temperature resistance, corrosion resistance, etc., can effectively extend the service life of brake pads, which is ultra-fine graphite powder used in lubricating and wear-resistant products.

Ultrafine graphite powder as a special graphite powder for brake pads, used in the production of brake pads, what is needed is one of the specifications of ultra-fine graphite powder, ultra-fine graphite powder is not only small particle size, its carbon content is also very high, through the production process, the carbon content of ultra-fine graphite powder can reach above, will further improve the conductivity of ultra-fine graphite powder, in this way, ultra-fine graphite powder is used to produce various conductive products, ultra-fine graphite powder is used in lubrication, conductive, metallurgical and other industrial production fields, is a good industrial production raw material.

Graphite powder is a commonly used lubricant in brake pads, with a layered crystal structure, the material is divided into natural graphite and artificial graphite, and different particle sizes have different effects on brake pads. Natural graphite is better at improving the wear rate at low temperatures than artificial graphite, but artificial graphite is better than natural graphite at medium and high temperatures.

Graphite must be used in the production of synthetic brake pads, graphite is divided into two kinds: earthy graphite and flake graphite.

Artificial graphite, as the name suggests, is graphite made by artificial methods.

The artificial graphite particles produced by our factory are high-quality carbon materials with high carbon content and porosity for high-temperature roasting and graphitization, and then finely processed into iron-black irregular particles, the main particle size is between 8 mesh and 100 mesh, and the special particle size can be customized according to customer requirements. This product has the characteristics of high carbon content, high porosity, low hardness and low thermal conductivity. It is used for friction materials, which can reduce the thermal decline of friction materials, stabilize the friction coefficient of friction materials, and meet the comfort requirements of disc brake pads such as stable performance, small wear, friction noise, and jitter, which people are increasingly concerned about, and is an ideal material for disc brake pad manufacturers at home and abroad.

Artificial graphite circulation is better than natural graphite, natural graphite capacity is high, due to poor circulation of the reason for the choice of electrolyte is more important, natural graphite is softer, but the compaction is too high, its particles may be deformed, and the liquid absorption capacity will drop sharply.

At present, the anode materials of lithium-ion batteries are mainly graphite (including natural graphite and artificial graphite), and the advantages and disadvantages of these two are:

Natural graphite generally appears like graphite schist, graphite gneiss, graphite-containing schist and metamorphic shale and other ores. Natural graphite can be divided into crystalline graphite and cryptocrystalline graphite according to its crystalline form.

The main raw material for the manufacture of artificial graphite is powdered high-quality calcined petroleum coke, in which asphalt is added as a binder, and a small amount of other auxiliary materials are added. After all kinds of raw materials are matched, they are pressed into shape, and then processed in a non-oxidizing atmosphere of 2500 3000 to make them graphititized. After high temperature treatment, ash, sulfur and gas content are greatly reduced due to the high cost of artificial graphite products, most of the artificial graphite carburizers commonly used in foundries are recycled materials such as chips, waste electrodes and graphite blocks when manufacturing graphite electrodes, so as to reduce production costs.

Petroleum coke is a widely used carburizer at present.

You can add a part of the artificial, but not all of the artificial, the effect of the artificial is not as good as natural graphite, but the ** is low, for cost considerations can be appropriately added a part, but the quality is certainly not as good as all natural graphite.

I don't know if you have used calcium sulfate whiskers, many manufacturers have added it, the wear resistance is good, and ** is a little lower than other additives, you can search for it, or add.

Synthetic fibers are better.

Carbon fiber (CF) is a new type of fiber material with high strength and high modulus fiber content of more than 95%. It is a microcrystalline graphite material made of organic fibers such as flake graphite microcrystalline stacked along the axial direction of the fiber, and obtained by carbonization and graphitization treatment. Carbon fiber is "soft on the outside and rigid on the inside", the weight is lighter than that of aluminum, but the strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus, which is an important material in the national defense and military industry and civilian use.

It not only has the intrinsic properties of carbon materials, but also has the soft processability of textile fibers, and is a new generation of reinforced fibers.

Carbon fiber has many excellent properties, carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat and conductivity between non-metal and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance, good X-ray transmittance. Good electrical and thermal conductivity, good electromagnetic shielding, etc.

Compared with traditional glass fiber, the Young's modulus of carbon fiber is more than 3 times that of it; Compared with Kevlar fiber, Young's modulus is about 2 times that of Kevlar fiber, and it is insoluble or swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance.
