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.

Graphite powder has the cause of self -lubrication performance analysis

Graphite powder is a wear -resistant material, and its self -lubrication performance is its most important feature. Graphn powder has a good self -lubrication performance due to its special layer -shaped crystal structure. The following are the analysis of the reasons for the self -lubricating property of graphite powder:The carbon atoms in graphite lattles are arranged in hexagonal on different planes. The distance between the carbon atoms in the same plane layer is 1.42 meters, and the distance between the carbon atom of each plane layer is 3.35. They are staggered along the same direction, repeat the position of the first plane in the third plane, the fourth plane repeats the position of the second plane, and so on. In each plane layer, because the carbon atoms are relatively tight, the binding forces between them are relatively large, and the carbon atom between layers and layers is far from each other, which is easy to separate and relatively slide. This is the main reason why gr

Purification method of graphite

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has lower costs. This is a major advantage of the flotation method for purifying graphite. However, when using the flotation method to purify graphite, it can only achieve a limited improvement in the grade of graphite. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomers, but also is not conducive to protecting the large flakes of graphite. Therefore, using flotation to further improve the graphite grade is not economical or scientific. To obtain high carbon graphite with a carbon content of over 99%, it is necessary to use chemical methods to purify the graphite.（1） Chlorination roasting methodThe low roasting temperature and low chlorine consumption of the chlorination roasting method greatly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after tr

Several methods for preparing nano graphite powder using natural graphite

(1) Detonation cracking methodThe detonation cracking method utilizes the properties of graphite that can accommodate foreign negative ion layers to form expandable graphite or lower order GICs, where the ion layer contained is called the insertion layer. In expandable graphite or low order GICs, the insertion layers are regularly arranged in graphite layers. During detonation, the insertion layer rapidly decomposes and releases a large amount of gas, impacting the graphite layers and pushing adjacent graphite layers apart to prepare nano graphite thin sheets. During the detonation process, * * plays two roles simultaneously: firstly, it releases a large amount of heat during the explosion, causing the decomposition of expandable graphite or lower order GICs; The other is to use the shock wave generated during detonation to crush the graphite sheet, achieving the effect of refining the graphite, thereby preparing flake graphite with smaller diameter and very thin thickness.At present,

Silicon fossil system

Chemical gas deposition (CVD) method) methodSilicon and carbon -containing gases have a heat decomposition through high -temperature graphite matrix, and SIC is deposited on the surface of the graphite matrix. The raw materials are trichloronetas (CH3SIC3), silicon chloride, hydrogen, silicon steam, etc. The deposition temperature range is wide, from 1175 ° C to 1775 ° C. The SIC layer generated by this method is very dense, the thickness is uniform, and the general thickness is about 0.1 to 0.3mm. However, the combination of SIC and graphite matrix is a combination of pure machinery, and the combination force is weak. When the temperature changes, the SIC layer is prone to cracking and peeling.Chemical Qi Evidence Method (CVR)The raw materials are coke powder and excessive quartz sand or non -fixed silicon powder. Chemical reactions occur when heated to 2000 ° C to generate SIO vapor. SIO steam and carbon -based reactions generate SIC. There is no obvious interface between SIC layers

Graphite products manufacturers introduce the use of graphite block on cement back kiln in detail

The concrete flip kiln is the insulation machinery and equipment that conducts actual operation under negative pressure. The sealing situation on both sides is immediately associated to the production of cement clinkers, quality and energy consumption. In the work of improving and improving kiln heads and kiln tails, it is one of the effective ways to flip the high -yield and energy -saving of the kiln chemical plant. However, because the working conditions on both sides of the flip kiln are extremely high, not only the temperature is high, but also has flipping and shaking together. Therefore, the sealing work of the flip kiln chemical plant is both the key and difficult. Graphite block has the inevitable heat resistance characteristics and excellent authenticity characteristics, which can achieve a good regulation of flip kiln sealing. Therefore, in China, the graphite block has been used as a sealed material in the early 1950s. At this stage, the current stage. The use of use is st

Scales graphite processing

Scale 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

Floating 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
