Scales graphite is a product that is widely used in refractory materials and coatings in the metallurgical industry. Such as magnesium carbon bricks,。, etc. Now used as anticorrosive materials. Scales graphite is a rust -proof primer made of charcoal black, talc powder and oil, which has good chemical resistance and solvents. If you add chemical pigments such as zinc yellow to the formula, the rust -proof effect is better. During use, thermal shock resistance is strong and has good corrosion resistance. It is the main carbon raw material used in conjunction with refractory materials. It has an important impact on the brushing and high temperature intensity of carbon -binding materials such as magnesium carbon bricks. In the actual production process, carbon -combined refractory materials have strict requirements for the purity, gray, particle size and shape of the scales graphite. The structure and function of its high -temperature firing now depends to a large extent on the moisture of high temperature silicate liquid to graphite tablets. During the humidity, the silicate liquid phase flows into the granular gap under the action of capillary. The scales graphite particles are combined through the adhesion force between them, forming a layer of film around the sheet shape, and the continuous body is formed after cooling, forming a higher binding interface with it.
The surface tension of the scale graphite is small, and there is no defect in large areas. The surface is about 0.45%of volatile organic matter, which makes the wetting of graphite worse. The strong hydrophobicity of the scales graphite has deteriorated the liquidity of the pouring materials. It is easy to gather and cannot be evenly scattered in the refractory material, so it is difficult to prepare uniform and fine -dependent refractory materials. If the two are not wet, the sheet graphite particles will form a gathering collective. The silicate liquid phase is limited to the gap between the particles to form isolated, and it is difficult to sinter at high temperature to form a fine complex. Or when heating, the volume expands rapidly (up to 300 times) to suffocate the flame, and at the same time produces expansion substances, can isolate the flame, delay or interrupt the spread of flames. good. Now the company's Perkin Elmer testing equipment from the United States has advanced equipment, providing a reliable guarantee for the excellent and long -term stability of the product quality. Now the company solemnly promises; the quality price of the same quality is better, and the quality of the same price is better. The battery -specific graphite powder we produce is a national quality product.
2023-04-03In recent years, graphite molds have continued to impact model shell sales markets with their high -quality characteristics, and have become the new darling of the machinery processing industry. The manufacturers of Kobwee Grapeite products below told everyone that the shortcomings and preventive methods of the heat treatment process of graphite mold.
In fact, many production manufacturers of high -purity graphite board are unclear how to differentiate the quality of high -purity graphite board. Some manufacturers say that they are used as fine particles, and some manufacturers say they are the secret recipes of their ancestors. In fact, the only key to judge the quality of high -purity graphite board is to query its density.In the electroplating and electrolytic industry, many manufacturers only favor the conductivity equivalent of high -purity graphite boards and ignore its density. Assuming that the density of high -purity graphite chips is small, it is very easy to form air holes on the surface layer. It is very easy to enter the lithium battery electrolyte of lithium battery, and then form a graphite pole. Period of use. It is convenient to use in the wear -resistant steel industry and can also be used to high -density fiber board industry.2023-04-10How to distinguish the quality of high -purity graphite board?
