What are the characteristics of high-purity flake graphite

High purity flake graphite has good high-temperature resistance, conductivity, thermal conductivity, lubricity, and chemical stability. Graphite powder manufacturers are widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, fire protection, electronics, medicine, military industry, aerospace, etc. It plays an increasingly important role in the national economy and is an indispensable non-metallic raw material for modern industrial and high-tech development. Trace impurities have a significant impact on the performance of graphite products. The higher the carbon content of high-purity flake graphite, the better its performance as a functional material.In order to analyze trace impurities in high-purity flake graphite, the sample is usually ashed or wet digested to remove carbon, the ash is dissolved in acid, and the impurity content in the solution is then determined. The ashing method does not require the use of ultrapure acids to dissolve a

How to identify the quality of graphite board

The graphite board is not rusty for some manufacturers, but in fact many manufacturers have applied for more than ten years, and they are unclear how to distinguish the quality of graphite boards. This is only a kind of summary of the product, which is very vague.Speaking of how to distinguish the advantages and disadvantages of graphite boards, there is only one key, which is the relative density. The following discusses the necessity of using the Moore quality formula from many levels.The battery electrolyte is very prone to infiltration, resulting in the oxidation of the graphite board air, which is greatly shortened by the use period. The density is high, and the cost of application is increased, so it is important to choose a suitable graphite board manufacturer.2. In the field of resistance, the key to the graphite board is used to pad the method, which has a moisturizing effect. The relative density of the graphite board here is greatly displayed. Very easy to fall, the surface

The application of scales graphite in the coating industry

The functional fillers of scales are mainly used for anti -corrosion coatings, fireproof coatings and conductive coatings.As an anticorrosive material, it has a good rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent corrosion performance. If you add chemical pigments such as zinc yellow to the formula, its rust -proof effect is better. EssenceIt is used as a fireproof filler. It is expandable graphite. It is a graphite intervertebral compound obtained by natural graphite scales. 300 times) suffocating the flame, and at the same time, the expansion material is generated to achieve the effect of isolation of the flame, delay or interrupting the flame spread, and it is not burning, soft, high on the surface, and good coach layer. However, the volume and dosage of the expansion body should be appropriate. Tests show that 150um particles, 30%expansion multiple, and 5%of the amount are the most suitable.Scales graphite can be directl

The shortcomings and prevention of graphite mold heat treatment process

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. It is confirme

The position and role of carbon industry in the development of the national economy

Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea
