What is the application scope of industrial graphite powder

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 advantages of high -purity graphite products

What are the advantages of high -purity graphite products? High -purity graphite has the characteristics of graphite that has undergone unique production and processing, and has the characteristics of anti -corrosion, good heat transfer, and poor possession. Several advantages of high -purity graphite products:1. heat resistance: The solution point of the graphite is 3850 ± 50 ° C, and the melting point is 4250 ° C. Even if the high temperature and high voltage and electricity are burned, the net damage is not large, and the line expansion coefficient is not large. Graphite's compressive strength increases with the temperature, and the graphite compressive strength is doubled at 2000 ° C. The chemical change temperature of the heat release reaction welding at the construction of the heat control welding project is very high, so that the raw materials of the welding mold application must be heat -resistant.2. Conductivity and heat transfer: The conductivity of high -purity graphite is

Is ultra -fine graphite powder be microflashed?

The 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

The black PCB is difficult to see the wiring clearly, which brings difficulties for maintenance

From this point of view, the color of PCB has nothing to do with the quality of PCB. The difference between black PCB and blue PCB, yellow PCB, etc. The difference between PCB is different in the color resistance paint color. If the PCB design and manufacturing process is exactly the same, the color will not have any impact on performance, and it will not have any eff

Popular Science Knowledge of Graphite Crucibles

Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal material crucibles. In graphite crucibles, there are three types: regular graphite crucibles, irregular graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles differ in performance, main uses, and application standards, resulting in differences in commonly used raw materials, production methods, production processes, and product specifications and models.The main raw material of graphite crucible is pure natural graphite in crystalline form. Therefore, it maintains the various physical and chemical characteristics of pure natural ink.Namely, it has excellent thermal conductivity and heat resistance, and has a small coefficient of linear expansion throughout the high-temperature application process. It has certain strain resistance performance for rapid heating and quenching. Strong corrosion resistance to acid and alkaline solutions, with high-quality orga

Why can graphite blocks be used as sealing rings

In the graphite industry, it is well known that graphite products are widely used in many industries. It is believed that friends who often walk in graphite rings know about graphite sealing rings. So why is graphite used as a sealing material? This is a question worth exploring.Graphite has characteristics that cannot be replaced by other metal materials, such as conductivity, good thermal conductivity, and excellent corrosion resistance. Choosing it as a sealing material also has its own special characteristics. Carbon graphite rings have physical and mechanical properties such as high temperature resistance, self-lubrication, low friction coefficient, wear resistance, and low thermal expansion coefficient. Therefore, graphite sealing rings can be seen in various industrial sectors such as papermaking, textile, and medicine.Moreover, graphite blocks can not only be used as graphite sealing rings, but also as various types of graphite machined parts in other industries.
