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

The application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl

How does pungeable graphite produce?

Because graphite is a non -polar material, it is difficult to use the small polar organic or inorganic acid intercourse alone, so oxidant is usually used. The chemical oxidation method is generally soaked in the solution of the natural scales in the solution of the oxidant and plug -in agent. Under the action of a strong oxidant, graphite is oxidized, making the macromolecular molecule of the graphite layer into a plane macromolecular with a positive charge. Due to the extrusion effect of the iconic charging between the plane macromolecules with a positive charge, the spacing between the graphite layer increases, and the plug -in agent is inserted between the graphite layer and becomes a graphite. When heating at high temperature, puffed graphite will quickly shrink, and the contraction multiple is as high as tens to hundreds or even thousands of times. The apparent volume of shrinking graphite reaches 250-300 ml/gram or more. The contracted graphite is worm -like, with a size of 0.1
