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

Why can graphite blocks be used as sealing rings

In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.

What are the reasons for the low initial efficiency of lithium carbide graphite negative electrodes

1. Low specific surface area: As you mentioned, the specific surface area of waste graphite is usually low, which leads to a decrease in the contact area between the electrolyte and graphite, affecting ion insertion and extraction during the initial charge and discharge process, thereby reducing the initial Coulombic efficiency. Compaction and coating treatment can increas

Flake graphite processing

Flake graphite is obtained by mining and processing from graphite mines. The types of ore mined are different, and when processing flake graphite, it is also necessary to process it correctly based on the characteristics of the graphite ore. So how should we proceed with the operation? Let's have a simple understanding of flake graphite below.1. Mineral processing method for flake graphite cryptocrystalline graphite.Cryptocrystalline graphite crystals are very small, hence also known as microcrystalline graphite. Graphite particles are usually embedded in clay and difficult to separate. Due to the high grade of the raw ore (usually containing carbon), many graphite mines directly crush and process the extracted ore, selling graphite powder products.2. Mineral processing method for crystalline graphite in flake graphite.The natural floatability of crystalline graphite is good, and it is basically used in China. Due to the particle size of graphite sheets being one of its most important
