    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 to a few millimeters. It has a large number of common mesh micropores inside. It is called a shrinking graphite or graphite worm. Shining graphite has many special excellent performance. Graphite and its expansion graphite can be used in industrial sectors such as steel, metallurgy, petroleum, chemical machinery, aerospace, atomic energy, etc., and their application scope is very common. For example, expansion graphite can be used as flame retardants and products for flame retardant materials and products, such as fireproof plastic products and fire -resistant anti -static coatings.

    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.

    What are the key applications of graphite shells?

    With the development of science and technology, graphite slowly turns into selected raw materials for mold production with its excellent physics and organic chemical characteristics. Graphite molds are generally used in various industries. Below I take the old iron to take a look at the key use of graphite mold!1. Rare metal forging and semi -continuous forging for graphite moldIn recent years, countries around the world have been marketing and promoting the situation of fusion metal materials and continuously (or semi -continuous) production and manufacturing bars or pipes. China has gradually selected this method at the level of copper, alloy copper, aluminum, aluminum alloy profiles. Artificial synthetic graphite is a continuous forging or semi -continuous forging as a rare metal. Manufacturing practice has proved that because of the selection of graphite mold shells, it has excellent thermal transmission performance (the heat transfer performance decided to condense the condensate
