Even if the chemical equipment is melted, it is still safe and intact. When the asbestos products are at 500 ° C, the crystalline water inside will decompose to make itself powder and lose its effect. In many industrial fields, it is carried out at high temperatures. The nature of scales graphite makes it more suitable for this role.2. Synthine graphite is easier to useThe pads of scales graphite are only half of asbestos products, which means that to achieve the same sealing effect, the power of tightening the screw can be much smaller. The scales graphite not only has the above obvious characteristics, but also has excellent sealing performance, good compression, elasticity, elasticity, elasticity, The characteristics of good antioxidant, strong self -lubrication and plasticity, good conductivity, high gravity, an
2023-07-27Natural scales graphite is a high -quality refractory raw material, but it is difficult to prepare uniform and dense non -fixed refractory materials because the surface of graphite has hydrophobicity. Therefore, the surface of the graphite needs to be modified so that the surface is changed from hydrophobic to hydrophilic, in order to enable graphite to be widely used in refractory materials. Generally speaking, most of the surface modification uses the modified agent to modify the powder. The following introduces a variety of graphite modification methods.First, the wetness of scales graphite and its application limitations. There is no shortage of graphite area, with small surface tension, and about 0.45%of volatile organic objects on the surface, all of which make the wetness of graphite worse. The strong hydrophobicity of the graphite surface makes the fluidity of the pouring materials worse, graphite is easy to reunite, it is difficult to prepare uniform and dense non -fixed -sha
2023-07-27The scale graphite is high -pressure metamorphic. After weathering, it is generally blue -gray, yellow -brown or gray -white. It is mostly produced in tingling rocks, sliced rocks, crystalline litter and silicon hacks. Symbiosis is complicated, mainly consisting of sheet -like crystalline carbon, accompanied by long -stones, Yingshi, Black Cloud Mother, Pymaline Mine, Magnetic Yellow Elephant Mine, Golden Stone and other miscellaneous minerals. The graphite in the ore is a chip -like or blade -shaped, and the black or steel gray is mainly existing between the long stones, the time, the transparency of the pyroxyl, and the permeability of the glitter. It has obvious directional arrangement and consistent with the layer. Scales graphite is mostly natural crystal graphite with a layered structure and looks like fish scales. It belongs to the hexagonal crystal system. The crystalline state is good, the particle size is 0.05 ~ 1.5 microns, the thickness of the thin piece is 0.02 ~ 0.05 mm,
2023-07-27Scales graphite has a strong heat shock resistance and good corrosion resistance. It is the main carbon raw material used in carbon resistance materials. It has an important effect on the corrosion resistance and high temperature intensity of carbon bricks such as magnesium carbon bricks. Essence In the actual production process, carbon -combined refractory materials have strict requirements for the purity, gray, particle size, shape and addition of scales graphite.A large number of studies have shown that the purity of graphite is directly related to the high temperature resistance strength of magnesium carbon bricks and the melting loss rate in use. The high temperature resistance of magnesium carbon bricks increases with the increase of graphite purity, which is the result of different micro -structures of magnesium carbon bricks. Magnetic carbon bricks made of lower -purity graphite have a larger thick pore and higher pore rate than high -pure graphite, which may be related to the

Different applications of scales graphite and nuclear graphite.Scales graphite has excellent performance such as high temperature resistance, heat conduction, conductivity, lubrication and other excellent performance. It is an indispensable resource for the cultivation of the development of emerging industries and the transformation and upgrading of traditional industries. The nuclear graphite is mainly used as graphite materials in the nuclear industry, including the atomic reactor with neutron chronic agents and reflexes, the production of hot column graphite for the production of isotopes, and the spherical graphite and block graphite for high -temperature gas and cold piles.2. Scales graphite and nuclear graphite are different branches of graphite materials.Graphite -like crystals are complete, thin and tough, their physical and chemical properties are stable, and they have good temperature resistance, lubrication, conductivity, heat shock resistance, corrosion resistance and a
2023-07-26At 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
