What are the nature of ultra -fine graphite?

Ultra -fine graphite powder is one of the categories of graphite powder. The raw material of ultra -fine graphite powder is natural scales graphite. The airflow crusher or ultra -fine pieces is used to crush the natural scales graphite. The particle size of ultra -fine graphite powder reaches 6 ~ 10 μm, which is the ultra -fine graphite powder.The preparation process of ultra -fine graphite powder is: natural scales graphite and raw materials focus from compressed air to enter the crushed room by adding feed sprayer, sprayed in the crushing room, spray ultra -high -speed airflow at the crushed room , Fricate into microfimm, with a microfimm airflow, discharge from the exit tube into the hierarchical room, separate the thicker particles, and crushed it again by the rebate tube. Ultra -fine graphite powder was produced.Ultra -fine graphite powder can be widely used in the fields of conductive materials, wear -resistant lubricating materials, atomic energy industry and national defense i

What are the main applications of graphite electrodes in?

(1) Used for electric arc steelmaking furnaces. Electric furnace steelmaking is a major user of graphite electrodes. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace,Utilize the high-temperature heat source generated by the arc between the electrode end and the furnace material for smelting.(2) Used for submerged arc furnaces. The submerged arc furnace is mainly used for the production of industrial silicon and yellow phosphorus, and its characteristic is that the lower part of the conductive electrode is buried in the furnace material,Arc is formed within the material layer and the heat energy emitted by the resistance of the furnace material is used to heat the furnace material. A submerged arc furnace with a high current density is requiredGraphite electrodes are required.(3) Used for resistance furnaces. The graphitization furnace for producing graphite products, the furnace for melting glass, and the electric furnace for producing silico

Classification of Graphene

There are two classification methods for graphene. One is based on the number of layers, which can be divided into four categories: single-layer, double-layer, few layer, and multi-layer products; Another type of product can be divided into three categories according to its form: powder, slurry, and film. Graphene powder and graphene thin film are currently the two main forms of graphene materials. The former is mostly doped in other materials and is widely used in coatings and lithium-ion batteries; Graphene thin films are widely used in the fields of electronics, photons, and optoelectronic devices due to their advantages of transparency, conductivity, and flexibility. Different graphene products have certain differences in raw materials due to different preparation methods. Graphene powder is mainly formed by physical or chemical methods, and the main raw material is natural graphite. Graphene thin films are mainly deposited by chemical vapor deposition, and their raw materials are

Preparation process and application of ultrafine graphite powder

Ultrafine graphite powder is one type of graphite powder. The raw material of ultrafine graphite powder is natural flake graphite, which is crushed using an airflow grinder or ultrafine micro grinder. Ultrafine graphite powder with a particle size of 6-10 μ m. It's ultrafine graphite powder.The preparation process of ultrafine graphite powder is as follows: natural flake graphite and raw material coke enter the crushing chamber through a feeding injector with compressed air, and are distributed at the nozzles outside the crushing chamber to inject ultra-high speed airflow into the crushing chamber, causing the coke powder to collide and rub with each other at high speed to form micro powder. The airflow with micro powder is discharged into the grading chamber through the outlet pipe, separating the coarser particles and being crushed again through the return pipe, The remaining micro powder is collected in stages using a cyclone separator and a bag collector. Ultrafine graphite powder

Mold graphite

The casting industry in the mechanical industry uses graphite materials as molds such as pressure casting, centrifugal casting, and hot squeeze of super hard alloy. It can use graphite molds as large as train wheels and small as small as precision parts. Graphite molds can be repeatedly used for multiple times. After the molding, the casting has a high degree of smoothness, and some can be used without further processing. The graphite material used for casting molds should be graphite with a dense texture, low thermal expansion coefficient, and good antioxidant performance. Graphite, which is used for casting with large casting size, can be composed of thicker particle size. It is used for casting small precision parts The graphite must be graphite with fine particles. The number of graphite used to make molds in China is large. In 2005, it was continuously cast about 1500T with graphite and sintering molds were estimated to cost 4000T.
