The purpose and function of graphitization

Time：2023.09.05Browse：1: Share:

Graphitization is a high-temperature heat treatment process in which the roasted product is placed in a high-temperature furnace and heated to a temperature above 2300-2500 ℃ in a protective medium, transforming the hexagonal carbon atom plane grid from a two-dimensional disordered arrangement to a three-dimensional ordered graphite structure.

Its purpose and function are:

1. Improve the thermal and conductive properties of materials;

2. Improve the thermal stability, thermal shock resistance, and chemical stability of materials;

3. Improve the lubrication and wear resistance of materials;

4. Remove impurities from the material and improve purity;

5. Reduce the hardness of the material to facilitate mechanical processing.

Graphite products and other purposes

Defense industryIn the defense industry, the nozzle of solid fuel rockets is also used to make solid fuel rockets, the nasal cone of the missile, the parts of the universe navigation equipment, the insulation material and the anti -ray material.Anti -anti -rust and anti -rust materialGraphite can prevent boilers from scaling. Tests from relevant units show that adding a certain amount of graphite powder (about use per ton of water) to the water can prevent the surface of the boiler from scaling. In additionWith the continuous development of science and technology, people have also developed many new uses on graphite. Flexible graphite products. Flexible graphite, also known as expansion graphite, is a new graphite product developed in the age. The United States has studied successful flexible graphite sealing materials, solving the problem of atomic energy valve leakage, and then Germany, Japan, and France have also begun to develop and produce. In addition to the characteristics of n

Which of the scale of the number of meters is more?

Scales graphite has many specifications. Different specifications are determined according to different goals. The number of scale graphite ranges from 50 ~ 12000 mesh. A specification of scales graphite, so why is the 325 -purpose scales graphite application very wide? The following Jinhui graphite editor will analyze it in detail:Scales graphite is a natural scales graphite as the processing raw material. After machinery, it can be crushed to 325 mesh graphite powder. The 325 -mesh scales graphite is purified and other processed. It can be processed into a carbon -containing 325 -mesh graphite powder with a carbon content of 99%or 99.9%. Such a 325 -mesh scales graphite has good conductivity, high temperature resistance, and lubrication performance. The use of high carbon -containing 325 mesh scales graphite is used in different industrial production areas.Graphite powder is processed and highly purified on the basis of scales graphite to remove impurities, so that the purpose of 32

What is the role of scales when galgling?

The application of scales graphite is widely used in industries. Mulchogenic sand is one of the applications of them. Cover sand refers to the sand or core sand with a solid resin film on the surface of the sand grain. In the middle, scales need to be used. Today, I will explain what the scales have the functions when gog graphic is covered with membrane sand:The scaled graphite is used as a lubricant in the lubricant in the sandy sand. The littering of the luster sand can play a lubrication and high temperature resistant role in the sandwich sand. For the requirements of scales with scales in gifsta, it is required to be lubricated as a lubricant and high melting point, and the littering of the lubrication is a natural scale graphite with good lubrication. Carbon content. The melting point of the scale graphite itself is very high. After the production process processing, the high temperature resistance of scales graphite with scales with scales will be higher, and the lubrication ef

What are the characteristics of high-purity flake graphite

High purity flake graphite has good high-temperature resistance, conductivity, thermal conductivity, lubricity, and chemical stability. Graphite powder manufacturers are widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, fire protection, electronics, medicine, military industry, aerospace, etc. It plays an increasingly important role in the national economy and is an indispensable non-metallic raw material for modern industrial and high-tech development. Trace impurities have a significant impact on the performance of graphite products. The higher the carbon content of high-purity flake graphite, the better its performance as a functional material.In order to analyze trace impurities in high-purity flake graphite, the sample is usually ashed or wet digested to remove carbon, the ash is dissolved in acid, and the impurity content in the solution is then determined. The ashing method does not require the use of ultrapure acids to dissolve a
