Artificial graphite characteristics

Crystal structureNatural graphite: Crystal development is relatively complete, the graphization of scales graphite is more than 98%, and the graphitization degree of natural micro -crystal graphite is usually below 93%.Artificial graphite: The degree of crystal development depends on raw materials and thermal treatment temperature. Generally speaking, the higher the thermal treatment temperature, the higher the graphite. The artificial graphite produced by industrial production is usually less than 90%.Organizational structureNatural scale graphite: It is a single crystal, which is simpler in the tissue structure. There are only shortcomings in crystalline learning (such as defects, wrong positions, errors, etc.). The grains of natural micro -crystal graphite are small, the clutter between the grains is arranged, and there is a hole after the removal of impurities, which shows the same sex in the macro.Artificial Graphite: It can be regarded as a variety of materials, including graphi

Graphite board antioxidant solution increases the period of use

After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good. After a variety of specifications of graphite boards with pre -immersed in the antioxidant protective film, its liquid can penetrate into the pores of the graphite board. The sexual protective membrane is exactly the reasonable blocking gas of this layer of protective membrane immediately touched with the graphite plate to produce oxidation reactions. Then it can reasonably resist the air oxidation of the graphite board and increase the use period of graphite board.The period of use of graphite boards has continued to increase, and the service life of traditional raw materials has already increased significantly.

Application of flake graphite in the coating industry

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings.As a anti-corrosion material, it is made with carbon black, talc powder, and oil as an anti rust primer, which has good resistance to chemical and solvent corrosion. If chemical pigments such as zinc yellow are added to the formula, its anti rust effect is better.The expandable graphite used as a fireproof filler is a graphite interlayer compound obtained from natural graphite flakes through chemical or electrochemical treatment. Under heating conditions, the expandable graphite rapidly expands in volume (up to 300 times), suffocating the flame and generating an expanding substance to isolate the flame, delay or interrupt the flame spread. It is also non combustible, has good softness, and has high surface energy, The carbonization layer has good strength. However, the volume and dosage of the expansion body should be selected appropriately. Exper

Graphite anode plate

Graphite anode is a graphite plate, block, or rod used as an anode for electrolytic cells in the electrolysis industry. It has characteristics such as high temperature resistance, good conductivity and thermal conductivity, easy machining, good chemical stability, strong acid and alkali corrosion resistance, and low ash content.There are two types of electrolysis industry using graphite anodes, one is aqueous solution electrolysis, and the other is molten salt electrolysis. In the past, the chlor alkali industry, which used to produce caustic soda and chlorine gas by electrolysis of salt water solutions, was the largest user of graphite anodes. However, the chlor alkali industry now widely uses the ion membrane electrolysis process for alkali production, and the graphite anode diaphragm method for alkali production has gradually been phased out. Therefore, the production of graphite anodes is in an extremely shrinking state. Currently, graphite anodes are only used in industries such

Graphite anode usage

In an electrolytic cell, the current flowing into the electrolyte from this point is called a graphite anode plate. In the electrolysis industry, the anode is generally made into a plate shape, so it is called a graphite anode plate. It is widely used in ferries, wastewater treatment, industrial anti-corrosion equipment, or as a special material.Compared with other materials, graphite anode plates have advantages such as high temperature resistance, good conductivity and thermal conductivity, easy mechanical processing, good chemical stability, acid and alkali corrosion resistance, and low ash content; Used for electrolyzing aqueous solutions, producing chlorine, caustic soda, and electrolyzing salt solutions to produce alkali; For example, graphite anode plates can be used as conductive anodes for electrolysis of salt solution to produce caustic soda. Graphite anode plates can be used as conductive anodes in the electroplating industry, making them an ideal material for various elect

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.

Basic overview of high-purity graphite?

High purity graphite is widely used in various industries, so its use is definitely very extensive. In fact, this high-purity graphite mainly means that the carbon content of graphite is more than 99.99%. It is also widely used in advanced refractory materials and coatings in metallurgical industry, stabilizers for military initiating explosive devices, pencil lead in light industry, carbon brushes in electrical industry, electrodes in battery industry, catalyst additives in fertilizer industry, etc. Of course, the scale crystals of the product are complete, thin and tough, with excellent physical and chemical properties.
