What is the advantage of expanding graphite?

Compared with other adsorption agents, expansion graphite has many advantages. If the activated carbon is used for water removal, it will sink after the absorption of oil. At the same time as absorbing oil, it also absorbs water, which brings difficulty in post -treatment; the expansion graphite has a large absorption of oil, floating on the water after oil absorption, easy to catch and recycled, easy to use processing processing Cleaning, combustion, heating extraction and other methods will not form secondary pollution.

Advantages and disadvantages of graphite purification methods

Flotation method is one of the conventional mineral purification methods that consumes the least energy and reagents, and has the lowest cost. This is the biggest advantage of flotation method for purifying graphite. However, using flotation to purify graphite can only achieve a limited increase in its grade. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomer, but also is not conducive to protecting the large scale of graphite. Therefore, using flotation to further improve graphite grade is neither economical nor scientific. To obtain high carbon graphite with a carbon content of over 99%, chemical methods must be used to purify the graphite.(1) Alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, which has the characteristics of low one-time investment, high product grade, and strong process adaptability. Moreover, it also has the advantages of conventional equipment and stro

The function and characteristics of scales graphite

Skin graphite, as a functional filler for coatings, is mainly used for anticorrosive coatings, fireproof coatings and conductive coatings. As an anticorrosive material, it is a rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent resistance. If you add chemical pigments such as zinc yellow to the formula, the rust -proof effect will be better.Scales graphite manufacturers believe that expansion graphite can be used as fireproof fillers. It is a graphite layer compound obtained by natural graphite thin slices as raw materials. Under heating conditions, the volume of expansion graphite quickly expands (300 times) to suffocate the flame, and at the same time, the expansion substance can be isolated, which can be isolate the flames, delay or interrupt the spread of flames, not burning, good flexibility, high surface energy, charcoal layer strength strength good. However, the volume and dosage of the expansion body should be appropriat

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.

Graphite products conductive material

Graphite is widely used in the electrical industry for electrodes, brushes, carbon rods, carbon pipes, mercury tubes, cashiers, cashmerers, telephone parts, televisions, coatings of televisions, and so on. Among them, the application of graphite electrodes is the most widely used. When smelting various alloy steel and iron alloy, use graphite electrodes. At this time, the powerful current passes through the melting area of the electric furnace to generate an arc, which translates the electric energy to the heat energy, and the temperature is increased to the left and right. So as to achieve the purpose of melting or reaction. In addition, when electrolytic metal magnesium, aluminum, and sodium, the anode of the electrolytic groove also uses graphite electrodes. The resistance furnace that produces rigid sand was also used as a furnace head conductive material with graphite electrode.

The difference between expanded graphite and ordinary graphene

Expanded graphite, also known as flexible graphite or vermicular graphite, is a new type of carbon material. Expanded graphite has many advantages, such as large specific surface area, high surface activity, good chemical stability, and high temperature resistance.
