Graphite dust

Graphite dust is a powder made of graphite with metallic luster.Graphite is a four -layer hexagonal laminar -shaped crystal carbon structure, with silver gray and metallic luster. Its main ingredients are fixed carbon, and can also contain a small amount of silica with a small binding or free of free, as well as elements such as lead, calcium, magnesium, iron, and other elements. Can be divided into natural graphite and artificial graphite. In the natural graphite, the naked eye can see the crystalline scale -like graphite, and the crystals that are not visible to the crystal of the dense lump are called non -styling graphite. Artificial graphite is made of coal, coke, asphalt, etc., and is made of a 3000 ° C high -temperature electric furnace. It is almost pure crystalline carbon, which is almost free of free silica compared with natural leggings.Graphite is a widely used non -metallic mineral. It has high temperature resistance, heat conduction, conductivity, lubrication, plastic an

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 physicss

The chemical properties of single -mass carbon at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; burning with oxygen at different high temperatures to generate carbon dioxide or carbon dioxide; Below, single -quality carbon is more likely to be oxidized by acid; at high temperature, carbon can also react with many metals to generate metal carbides. Carbon is restored and can smell metal at high temperature.Graphite is soft, black and gray; it is greasy and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3 to 5 along the vertical direction. The proportion is 1.9 ～ 2.3. The surface area is concentrated at 1-20m2/g. Under the isolation of oxygen conditions, its melting point is above 3000 ° C. It is one of the most temperature-resistant minerals. It can conduct electricity and heat conduction.There is no pure graphite in nature, which often contains impurities such as SIO2, Al2O3, Feo, CAO, P2O

The best way to improve the life of graphite boards to use antioxidant solution

The best way to improve the life of the graphite board is the success of anti -oxidation solution with the development of graphite boards. After delivery and use in many industries, there will still be more and more technical advantages and characteristics in many levels. Among them, the continuous improvement of processing work capacity will still be unusual in the advantages and performance levels of its talents. In more cases, they all feel that their technical standards will still be higher and higher. The selection generated will still have a difference.Therefore, what are the aspects of their technical advantages? Below my graphite board manufacturer in Shanxi Province will introduce the old iron in detail:The antioxidant solution has good performance. Generally speaking, in the whole process of the construction of graphite board projects, the provisions of anti -oxidation levels are getting higher and higher, especially as a wall insulation layer.

How to choose the scale of scales graphite size

Scales graphite has good conductivity and thermal conductivity. It is widely used in sealing, lubrication, metallurgy, chemical industry and other industries. Different industries have different requirements for the specific parameters of scales graphite. Choosing the correct graphite graphite is closely related to its effect. Today, I will explain the correct method of choosing the graphite size of the scale:1. The effect of scale graphite particle size on expansionThe degree of particle size on the expansion of scales also has a certain effect. After experiments, the expansion rate of scales graphite is directly proportional to the particle size of graphite. The expansion graphite has a rich pore structure. The smaller the grain size of the graphite. The smaller, the lower the expansion coefficient, and vice versa. Therefore, in the fields of sealing and fire -resistant coatings, large -scale scales should be selected as materials.2. The effect of scale graphite particle size on smo
