What aspects will endanger the use period of graphite board

First, the quality of the production and processing of graphite board is the direct cause of the life of the application of its application. Graphite board production and processing must be careful to reach the overall goal of the standard. For example, pre -immersing this level must be well -proportioned, so that its resistance is basically unremittingly consistent, so that the conductivity can be proportioned to prevent the entire production process from occurring in the process of production Some part is complete, but some of the erosion is serious, so that all personnel come out to consume.In the second place, the graphite board must have an excellent office environment, which is the fundamental to prolong life. During the entire production process, reduce the impact and clean up the office environment. It can check the power circuit on time, produce at the best temperature, and reduce the air oxidation of the gas to its air.In the end, high -quality graphite boards are used to im

Graphite high-temperature purification method

Graphite is one of the substances with the highest melting and boiling points in nature, with a melting point of 3850 ± 50 ℃ and a boiling point of 4500 ℃. However, the boiling points of silicate minerals are all below 2750 ℃ (quartz boiling point), and the boiling point of graphite is much higher than the boiling point of the impurity silicate it contains. This characteristic is the theoretical basis for high-temperature purification of graphite. Fill the graphite powder directly into a graphite crucible and heat it in a purification furnace filled with inert gas and Freon protective gas to 2300-3000 ℃ for a period of time. Impurities in the graphite will overflow, thus achieving the purification of the graphite. The high-temperature method generally uses high carbon graphite containing over 99% carbon purified by flotation or chemical methods as the raw material, which can purify the graphite to 99% 99%. By further improving the process conditions and improving the quality of the cr

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

The artificial synthesis process and equipment application of scales graphite

At present, the production process of scales graphite is to produce graphite products through the production of natural graphite ore through the production, ball grinding, and flotation, and provide artificially synthetic scale graphite production technology and equipment. Using this device, the grinding graphite particles can be reinstated into large -shaped graphite to improve the utilization rate of graphite. The following editor introduces the artificial synthesis process and equipment application of scales in detail:This device has two relatively rotating ring rules semi -round tanks, or two irregular semi -circular grooves that can be relatively rotated, one of which is fixed as a fixed ring groove, and the feed pores are engraved on the fixed ring groove; The power connection allows the power to drive it to rotate. It is a cycle groove, engraved with the material outlet, and the gap between the fixed ring groove and the mobile ring groove can be adjusted; when the two ring groo

1. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steel, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. High temperature metallurgy industry: Due to the small thermal expansion coefficient of graphite and its ability to withstand changes in rapid cooling and heating, it can be used as a mold for glassware. After using graphite, black metal can obtain castings with precise dimensions, high surface finish, and can be used without processing or slight processing, thus saving a large amount of metal.

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.
