2023-07-24When the scale graphite is used as a fire -resistant filler, it is an expansion of graphite powder. It is a graphite layer of inter -graphite compound obtained by natural graphite scales as raw materials. Under heating conditions, the volume of expansion graphite expands sharply (can reach 300 times) to suffocate flames, forming expansion together, which can be isolated flames, delaying or interrupting the spread of flames, not burning, flexible, high surface energy, and good coach layer. However, the volume and dose of swollen should be appropriately selected. Tests show that the best dosage is 150 μM particles, 30%expansion rates and 5%. The editor of the graphite manufacturer below introduces whether the scale graphite can be used as a non -metal filler and analyzes:Graphite can be used directly as a carbon conductive filler or a composite conductive filler for conductive coatings. However, due to the large increase in scale graphite, the function of the coating will become fragile
2023-07-241. Different applications of scales graphite and nuclear graphite.Scales graphite has good high temperature resistance, heat conduction, conductivity, lubrication and other properties. It is an indispensable resource for the cultivation of the development of emerging industries and the transformation and upgrading of traditional industries. Graphite is mainly used as graphite materials in the nuclear industry, including the atomic reactor with neutron slow agents and reflexes, the production of hot column graphite for the production of isotopes, and the ball -shaped graphite and block graphite with high temperature and cold piles.2. Scales graphite and nuclear graphite are different branches of graphite materials.The scales graphite crystals are complete, thin -shaped, good toughness, stable physical and chemical performance, and have good temperature resistance, lubrication, conductivity, heat shock resistance, corrosion resistance, antioxidant, etc. Scales graphite is a very promisi
2023-07-24Scales graphite is a crystalline crystal carbon. It has high electrical and thermal conductivity, high temperature resistance, stable chemical properties, low hardness and slippery. It is easy to adhere to the solid surface and can draw clear dark stripes on the paper. These excellent properties of the mineral selection process and minerals have made it widely used in industry. The following is the scales graphite minerals introduced by scales graphite manufacturers:Graphite ingredients, mining agents are mainly flotal, sometimes shaking sorting. This thin piece uses a static electricity selection method, but because the electrical selection needs to be fully dry and accurate, it is difficult to manage high -voltage power management in a humid environment, difficulty in processing fine particles, and cannot be promoted.In non -metal minerals, graphite is a relatively easy to float mineral. Therefore, scales graphite can only float well with foaming agents (such as pine oil oil, methax
2023-07-21Because the battery -specific graphene has the above nano -scale effect, good conductivity and excellent mechanical properties, it is widely studied by scientists from all over the world and produced the concept of "graphene lithium battery". Battery?1. anode materialDue to its unique two -dimensional structure, excellent electronic transmission ability, and large surface area of battery -specific graphene, it has a huge potential to replace graphite to become a new generation of lithium -ion battery negative materials. The lithium storage mechanism of graphene is similar to other carbon materials. Both sides of the elene can store lithium ions. At the same time, graphene can also store lithium because of the presence of folds. Therefore, theoretically its capacity may be twice the graphite, which is higher than 744mAh/g.In addition, graphene is mostly micr -nano -size, far less than block graphite, which makes the diffusion path of lithium ions shorter, and the laminar spac
2023-07-21Battery -specific graphite has good chemical stability. The specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low penetration. Therefore, it is widely used in making heat exchangers, reaction tanks, condenser, combustion tower, absorbing tower, absorbing tower , Cooler, heater, filter, and pump equipment, are widely used in industrial departments such as petrochemical, wet metallurgical, acid -base production, synthetic fiber, papermaking, etc., which can save a large number of metal materials.It is a material for casting, casting, suppression, and high temperature metallurgy. Because of its low heat expansion coefficient, it is resistant to cold and hot, it can be used as a casting mold for glassware. After the graphite is used, the black metal can get accurate size, smooth surface, high finished product rate Casting, can be used without processing or machining, saving a lot of metals. In the powder metallurgical process that p
2023-07-21There is no doubt that the performance of the battery -specific graphene is unquestionable, but is it necessarily suitable for lithium ion batteries? According to my clumsy opinion, graphene is not suitable for lithium ion batteries, please consider the following:1. Cost problemThe cost of using graphene as a conductive agent is much higher than that of ordinary charcoal black. The cost of lithium battery is the key control factor. Without reducing the cost of raw materials, even if the electrical performance of graphene is good, battery manufacturers cannot afford a few tons per ton. 100,000 cost consumption.2. Process problemsThe technical problems brought by the chip structure of battery -specific graphene are mainly preparation of electrode paste. The electrode paste requires good liquidity, decentralization and appropriate viscosity. The dispersing of graphene tablets in the electrode paste is a difficult problem, especially for especially The electrode paste cannot be decentrali
