Graphite powder has the cause of self -lubrication performance analysis

Graphite powder is a wear -resistant material, and its self -lubrication performance is its most important feature. Graphn powder has a good self -lubrication performance due to its special layer -shaped crystal structure. The following are the analysis of the reasons for the self -lubricating property of graphite powder:The carbon atoms in graphite lattles are arranged in hexagonal on different planes. The distance between the carbon atoms in the same plane layer is 1.42 meters, and the distance between the carbon atom of each plane layer is 3.35. They are staggered along the same direction, repeat the position of the first plane in the third plane, the fourth plane repeats the position of the second plane, and so on. In each plane layer, because the carbon atoms are relatively tight, the binding forces between them are relatively large, and the carbon atom between layers and layers is far from each other, which is easy to separate and relatively slide. This is the main reason why gr

Analysis of the scope of application of industrial graphite in graphite products

Graphite products maintain the original chemical properties of flake graphite, namely acid resistance, corrosion resistance and physical properties, namely high temperature resistance 3000C and low temperature resistance 204C. Its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses weight in air at 450°C by 1 % , the rebound rate is 15-50% (density 1.1-1.5). It also has strong self-lubricating properties. Therefore, graphite products have been widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics and so on.Using the characteristics of graphite, people have deftly made different types of products according to the needs of engineering: such as high-purity graphite products, flexible graphite products, composite graphite products and so on. In order to improve the performance, graphite and fiber (including synthetic fiber), graphite wire, metal mesh, and metal processing plate are combined to make

The four major development trends in the field of graphite mold

Under the harm of China's economic development and the prevalence of Internet e -commerce prevailing, the shuffle in the graphite mold industry will increase, and the company has encountered a lot of challenges and opportunities. Therefore, the company only has the future development trend of the field, and moderate transformation and development and adjustment can really take the initiative to take the initiative and obtain dominance.1. High -end and precise positioning will be more noticedThe different advantages of graphite molds decide that it has a wide industry prospect. Under the prerequisites for giving full play to their own advantages and improving the entire process, Commodities have gradually entered the customer's field of vision. Customers' requirements and expectations for high -end products are getting higher and higher. The tentacles of high -end products have long been widening to many customers. Market demand will slowly gather to high -end, and the sales and growth

The effect of battery dedicated graphite as negative electrode on lithium ion power battery fast charge performance

Since its inception, lithium -ion batteries have been widely used in multiple fields. At present, lithium -ion batteries are not only widely used in electronic products such as mobile phones, digital cameras, tablets, but also in the application of vehicle power supply. A certain breakthrough has been achieved; from the analysis of the future development of lithium -ion batteries: Fast charging lithium -ion batteries will become an important research direction for lithium -ion batteries.In order to improve the fast charging performance of the battery -specific graphite negative material, a series of graphite negative materials made of different coke materials were prepared through experiments. It also performed particle size, polarization, and XRD tests, which made a lithium -ion battery rate charging and rate charging. The cycle test and analyzed the test results.The effect of lithium ion power battery fast charging machine and the effect of battery -specific graphite on the battery

The relationship between scales graphite and nuclear graphite

1. Different applications of scales graphite and nuclear graphite.Scales graphite has excellent performance such as high temperature resistance, heat conduction, conductivity, lubrication and other excellent performance. It is an indispensable resource for the cultivation of the development of emerging industries and the transformation and upgrading of traditional industries. The nuclear graphite is mainly used as graphite materials in the nuclear industry, including the atomic reactor with neutron chronic agents and reflexes, the production of hot column graphite for the production of isotopes, and the spherical graphite and block graphite for high -temperature gas and cold piles.2. Scales graphite and nuclear graphite are different branches of graphite materials.Graphite -like crystals are complete, thin and tough, their physical and chemical properties are stable, and they have good temperature resistance, lubrication, conductivity, heat shock resistance, corrosion resistance and a

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.

Talk about the hazard factors before the use of graphite.

Talking about the dangers of the storage hazards before the use of graphite crickets, the harm of the natural environment of Graphite to the performance of the natural environment is accumulated over time, and the harm is very large. Generally, it is stipulated that it is stored in a natural environment that is clean and irritable. Let's put it on the fixed wooden shelf to support the molten aluminum graphite. Difficulty in transportation, although graphite has very good thermal resistance, it is a very very easy to crush object. In the whole process of application and transportation, it is necessary to pay attention, and it should not make it a serious injury and other conditions.The value in the sales market is not very high, in fact, it is wrong to think so. Graphite looks very simple, it is commonly used in installing a variety of liquid state. However, in the industry lacks it, it will have a very large problem. Except for the industry's chemical manufacturing industry, it is no
