2023-03-14Gaocunya micron graphite particles have very wide application areas: the appearance tube of the electronic information, the black -bottomed conductive coating of the display industry, the device, sensor and color decomposition of the liquid crystal display, the sensor and color decomposition of the liquid crystal display The three primary colors of the color LCD plasma are used to improve the launch effect and color mining contrast, ultra -fine tungsten, molybdenum silk system and other coatings, high -grade lubricating oil and lubricating fat manufacturing, high -performance battery foam nickel manufacturing industry, and light sensitivity Many industries such as film are widely used in high -purity sub -graphite particles.1. Fire resistance: Graphite and its products have a high temperature resistance and high -strength properties. In the metallurgical industry, graphite is mainly used to make graphite. Graphite is often used as a protective agent for steel ingots in steelmaking.2.
2023-03-14The size of the material particles determines its name. As you ask questions, micro powder is micron -level powder. In the graphite industry, micro powder generally refers to the diameter of 10 ~ 45 microns. Inside, special graphite powder below 5 microns.Ultra -fine graphite generally refers to graphite with fine particle size. Its particle size is thinner than ordinary microflower graphite. It is generally less than 5um, and the general particle size of microflower graphite is about 10 microns. Qingdao Risheng graphite focuses on ultra -fine graphite production.The specifications of ultra -fine graphite powder are generally between them, mainly used in powder metallurgical destruction agents, graphite, battery negative electrodes, and additives for conductive materials.Graphite powder is divided into: nano graphite powder, colloid graphite powder, scales graphite powder, ultra -fine graphite powder. The number of graphite powder specifications from 50 mesh, and the types of graphite
2023-03-14The expansion graphite was discovered in the early 1960s. Many countries like to use it to study, so that many unexpected results can be achieved. The so -called expansion can be increased by more? That's right, more than double or even double! It is new carbon material! Many people don't know much about expansion graphite!Graphite crystals are two -way large -molecular layer -like structures. The C atom in each plane is combined with the C -C co -price bond, and the layer is combined with weaker Van Dehua.The layered structure of graphite is very typical. Each layer is a carbon atomic layer. The carbon atom in the layer is a strong covalent bond with SP2 hybrid orbit, that is, 1 2S electronics and 2 2P electronic hybridization, etc. The hybrid track of the price is located on the same plane and forms σ bonds each other, while the two unsteady 2P electrons are perpendicular to the plane to form a two -key π. This layered structure of graphite makes a certain gap between layers. Theref
2023-03-14The difference between expansion graphite and expansion graphite is that expansion graphite is a process of expansion. It has a large volume, and the expansion graphite has no expansion. It has the characteristics of high temperature and rapid expansion. L.Swrite graphite natural graphiteA loose and porous worm -like substance obtained by insertion, water washing, drying, and high temperature puffed. It is one of the expansion graphite production equipment, mainly used for natural grinding processingProcessing link, H/L/MVertical grinding machineIt is a device specializing in graphite, which is very suitable for configuration as expanding graphite equipment.
2023-03-13The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g. This product is mainly used for flame retardant coatings, and its demand is very large.2. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi
2023-03-131. Scales graphite powderThe use of scales graphite powder is relatively wide, and it is also a primitive material that is processed into other graphite powder. Graphite specifications range from 32 meters -12000 mesh. The scales graphite powder is tough and has good thermal conductivity and corrosion resistance. It can be used as refractory material. , Dordic and lubricating materials, conductive materials, casting, sand rollover, pressure molding and high temperature metallurgical materials.2. Collagen graphite powderCollagen graphite is formed by the average dispersing of graphite particles below 2 μ meters. The colloid graphite is a thick -shaped suspended liquid. Collagen graphite powder has the performance of high -quality natural scales graphite. It has special antioxidant, self -lubricating and plasticity under high temperature conditions, and has good conductivity, thermal conductivity and attachment. It is mainly used in sealing and metallurgical release industries.3. Super
