2023-04-18Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque and solid. The density is 2.25 grams per cubic centimeter, the melting point is 3652 ° C, and the boiling point is 4827 ° C. The chemical properties are stable, corrosion -resistant, and it is not easy to react with drugs such as acid and alkali. Burning carbon dioxide in oxygen at 687 ° C. Oxidation can be oxidized by strong oxidatives such as concentrated nitrate and potassium hydanol. It can be used as an anti -wear agent and lubricant. High purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, and arc furnaces, and electric arc furnaces, electric arc furnaces, and arc furnaces, and electric arc furnaces. Arc lights, pencils of pencils, etc.Due to its special structure, graphite has the following special nature:(1) High temperature resista
2023-04-18Floating method is a type with less energy consumption and reagent consumption and low cost in the conventional purification method of minerals. Real limited improvement. For scales graphite, multi -segment grinding ore cannot be completely unbuttoned, but it is not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite quality. High carbide graphite with more than 99%must be pure graphite with chemical methods.(1) chloride roasting methodThe low roasting temperature and smaller chlorine gas consumption of chloride roasting method have greatly reduced the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to the treatment of hydrofluoric acid method. Compared with the recovery rate of chloride and roasting method, because the chlorine gas is poisonous and has strong corrosiveness, it requires high requirements for equipment operations. It requires strict requirements. Seal
2023-04-18The 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
2023-04-17Scale graphite is obtained by mining and processing of the graphite mine. The mined ore categories are different. When processing scales graphite, it is also correctly processed according to the characteristics of graphite ore. So how to operate? Let's make a simple understanding of scales graphite.1. Synthetic graphite crystal crystal mitigation processing method.Cain crystal graphite crystals are very small, so it is also called micro -graphite. Graphite particles are usually embedded in clay and are difficult to separate. Because the original ore product is high (generally carbon -containing), many graphite mines will be crushed directly by the ore adopted by graphite mines and sell them for sale. Graphite products.2. The method of chip graphite in the scales graphite.Crystal graphite has good natural floating nature and is basically used in China. Because the granularity of graphite sheets is one of its most important quality indicators, multi -level grinding is used in the sortin
2023-04-17The quality of scales graphite determines the product quality of the processed scale graphite powder. The scales graphite resources are natural graphite of the light crystal, which is formed by deteriorating quality under the action of long -term geology. The scales graphite crystals are scales -shaped. The scale of the scales of scales graphite and the amount of carbon content is the key factor affecting the quality of scales. The following editors will take you to understand:As the basic processing raw materials of various graphite powder products, the quality of scales graphite is an important condition. According to scales graphite quality, various parameters, etc., scales can be processed into graphite products such as scales graphite, ultra -fine graphite powder, high pure graphite, nanim graphite, colloid graphite and other graphite products. The scale size of the scales graphite determines the lubrication performance of processed. The larger the scale graphite size, the better
2023-04-14Graphite crystals have a hexagonal layer -shaped structure composed of carbon elements. The carbon atoms on the layer of flat plane are combined with powerful covalent bonds. Therefore, under appropriate conditions, a variety of chemicals such as acid, alkaline metals, and salt can be inserted into the graphite layer, and a new chemical phase -Graphite Intercities on compounds (referred to GIC). When this intervertebral compound is heated to an appropriate temperature, it can quickly decompose instantly, generating a large amount of gas, so that the graphite is expanded into a new substance of worm -shaped, that is, the expansion of the intervertebral compound of the expansion. graphite.The expansion graphite was first discovered by the German SChaufautl. In 1841, Schaufautl soaked natural graphite in a mixture of thick HNO3 and thick H2SO4. In 1963, he first applied for expanding graphite manufacturing technology patents and industrialized production in 1968.The above is some of the
