What are the characteristics of graphite bearings?

Graphite bearings are important high-temperature bearings that utilize the self-lubricating, high-temperature resistance, and chemical inertness of graphite materials to operate under high temperature and strong corrosion conditions that ordinary bearings cannot withstand. The main functions of graphite bearings are:

The future development trend of battery materials

With the continuous progress of science and technology, battery materials have received widespread attention and research in recent years. Battery material is a core component of the battery and has a vital impact on the performance and life of the battery. With the pursuit of green environmental protection and new energy, the future development trend of battery materials has also attracted much attention. This article will explore the future development trend of battery materials from the following four aspects.1. Research on new battery materialsAt present, lithium -ion batteries are the most common battery types in the market, but they have problems such as energy density, safety and cost. Therefore, the research of new battery materials has become a popular research field. For example, solid battery materials, high -performance capacitance materials, metal air battery materials, etc. are all current research directions. These new battery materials are expected to solve the problem

Graphite mineral classification

Graphite's process characteristics are mainly determined by its crystallization form. Crystal forms of graphite minerals have different industrial values and uses. Industry, according to the different crystals, divide natural graphite into three categories.1. Deep crystalline graphiteThe dense crystal graphite is also called block -like graphite. Such graphite crystals are obviously visible to the naked eye. The diameter of the particles is greater than 0.1 mm, which is concentrated in 0.1-1m/g than the surface area. This: Graphite is characterized by high quality. Generally, carbon content is 60-65%, and sometimes 80-98%, but its plasticity and slipperyability are not as good as scales.2. Scales graphiteGraphite crystals are scales; this is made of deterioration under high -intensity pressure, with large scales and fine scales. The characteristics of such graphite ore are not high, generally between 2 and 3%, or 10 to 25%. It is one of the best ore in nature. The floating, lubricabil

What are some related knowledge points about high-purity graphite?

The application fields of high-purity graphite include metallurgy, military, light industry, electrical battery industry, and fertilizer. Can it be called high-purity graphite? In order to make more people familiar with it, here are some related knowledge points about high-purity graphite for everyone? I hope you can bring some better help when choosing in the future.High purity graphite is widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry, and aerospace. It has high purity and high strength graphite properties. In fact, the existence of graphite flakes now makes graphite have excellent lubricity. Generally speaking, the larger the ordinary graphite flakes, the better their lubricity. When we use it, we need everyone to know that the graphite industry technology is still at a relatively low level in the world, and the products are mainly raw materials and initial processing products. Therefore, th

Graphite products production and processing in the middle of pressure molding and extrusion molding method

Modeling method is to put a certain total paste in the mold and specifications of the specified mold and specifications, and then press it from the top or below. Sometimes it also increases a certain working pressure on the paste from the left and right positions at the same time, so that the paste is reduced in the mold. The processing of semi -finished products has been checked by model refrigeration. Then accumulate. The molding machine equipment has a column -type pressure machine, which is also a stand -up pressure machine. Modeling method generally only press a piece of goods at a time, and the productivity is relatively low. However, it can be allowed to systematically squeeze and mold.The squeezing molding method is to squeeze the main cylinder of the paste of the paste -loaded manner. The pressure machine should be relatively installed in front of the previous installation and can be effectively disassembled and replaced. The front is equipped with a partition that can be mov

The shortcomings and prevention of graphite mold heat treatment process

Precautions during the storage process of carbon material raw materials

(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea

Introduction to carbon elements

Carbon is a very common element that exists in the atmosphere and crust in many forms. Carbon monouples have been recognized and used for a long time. A series of carbon compounds -organic matter is the foundation of life. Carbon is one of the ingredients of raw iron, cooked iron and steel. Carbon can form a large number of compounds in chemical self -combination, which is an important molecule in biology and business. Most molecules in organisms contain carbon.Existing formThe form of carbon existence is diverse, including crystalline single -quality carbon such as diamond and pulse graphite; there are fordless carbon and coal; there are complex organic compounds such as animals and plants; carbonate such as marble. The physical and chemical properties of single carbon depend on its crystal structure. High -hardness diamond and soft and smooth pulse graphite crystal structures are different, each with its own appearance, density, melting point, etc.CharacteristicsThe chemical propert

The difference between flake graphite and expanded graphite

Flake graphite is a type of natural graphite that, after being extracted and purified, generally appears in the form of fish scales, hence it is called flake graphite. Expandable graphite refers to flake graphite that, after acid washing and intercalation treatment, expands by about 300 times compared to the previous graphite. It can be used as raw materials for coils and flexible graphite. Below, let me introduce in detail the differences between flake graphite and expandable graphite:1. The use of flake graphite is more extensive than that of expandable graphiteIn industrial production, flake graphite not only has the function of expandable graphite, but also has much better conductivity, thermal conductivity, smoothness, and so on than expandable graphite. So its practical use in industry is becoming increasingly widespread.2. The production processes of flake graphite and expandable graphite are differentFlake graphite is mainly made by mechanical damage and grinding. Expandable g
