Graphite dust

Graphite dust is a powder made of graphite with metallic luster.Graphite is a four -layer hexagonal laminar -shaped crystal carbon structure, with silver gray and metallic luster. Its main ingredients are fixed carbon, and can also contain a small amount of silica with a small binding or free of free, as well as elements such as lead, calcium, magnesium, iron, and other elements. Can be divided into natural graphite and artificial graphite. In the natural graphite, the naked eye can see the crystalline scale -like graphite, and the crystals that are not visible to the crystal of the dense lump are called non -styling graphite. Artificial graphite is made of coal, coke, asphalt, etc., and is made of a 3000 ° C high -temperature electric furnace. It is almost pure crystalline carbon, which is almost free of free silica compared with natural leggings.Graphite is a widely used non -metallic mineral. It has high temperature resistance, heat conduction, conductivity, lubrication, plastic an

Who is related to the wear resistance of graphite products?

Graphite sells various models and specifications of graphite rods, graphite columns, graphite particles, graphite powder, graphite bearings, and graphite tubes, including lubrication, high purity, conductivity, and wear resistance. We can process various shapes of graphite products according to customer requirements.Graphite products have been widely used in industrial machinery due to their wear resistance and lubrication effects. In actual industrial production processes, the oxidation resistance of graphite products has always been a concern of the graphite industry. So what is the relationship between the oxidation resistance of graphite products?It can be seen that the self-lubrication of graphite depends on the presence of air and water. As a lubricating material, the critical value of moisture in the working environment of graphite products is 5g/m3. If it falls below this value, the friction coefficient of graphite products will increase. At room temperature of 300-400 degrees

Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe

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

The lubrication of sliced graphite is mainly reflected in two aspects

1. Silver-like Gention-Environmental atmospheric lubricationThe essence of lubrication of sheet -like graphite is its laminar crystal structure. The initial raw materials for preparation of expansion graphite are high -carbon -like graphite. Other chemical reagents such as concentrated sulfuric acid (more than 98%), hydrogen peroxide (more than 28%), and potassium permanganate are industrial -grade reagents. The general steps of preparation are as follows: At the appropriate temperature, add different proportion of hydrogen peroxide solution, natural scales and concentrated sulfuric acid to different programs, react for a certain period of time under continuous stirring, and then wash to neutrality, centrifugal, dehydrated, and dehydration. Dry vacuum at 60 ° C.2. Film graphite-solid lubricant and lubricant additiveThe lubrication performance of slices graphite is also affected by graphite particles. Some research and test results show that whether it is a natural piece of graphite or

The application temperature category of graphite board

So, how much is the application temperature category of graphite board?The application temperature category of graphite board: -200-650 ℃ (in the air), -200-3000 ° C (in non-air oxidation substances).The structure of high -temperature graphite board is atomic crystals, and the middle price is connected in the middle of the oxygen atom, resulting in a porous material that stabilizes the positive hexagon. Because the covalent single -key is a ion key with a high key that can be very high, it must be highly mechanical energy to be damaged.The average graphite board is 1200 degrees. There is no problem in the following use, such as: precision processing parts processing, spark -loading wire cutting, industry creation, etc. The high -quality graphite board with high -quality characteristics can withstand high temperatures above 3000 degrees. Because the graphite board uses high -quality graphite carbon raw materials, it reasonably reduce the pore rate and increase the volume density, which
