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

Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance. There are many specifications for casting special sliced graphite powder. In different cast production areas, different thermal scale graphite should be used with different aims of casting.

It takes a long time at a lower temperature to observe the obvious creep, but at a higher temperature, the creep can be almost linear increased, that is, the peristalsis at a lower temperature increases only several times, and the temperature rises at a few times at a few times. The intervals when Baidu increased the index.2. The creep of scales graphite is also proportional to the exerted stress. In the same temperature and the same time, the greater the stress applied, the greater the creep.3. The creep of scales graphite is also related to the final heat treatment temperature of graphite. The higher the thermal treatment temperature, the smaller the scales of graphite.For the analysis of micro -quality impurities in scales graphite, the sample is usually pre -grayed or wet to digest carbon removal, dissolved ash with acid, and then determined the impurities in the solution. The measurement m

The relationship between the micro -structure and anti -folding strength of the natural scales graphite sample is qualitatively analyzed. The two systems of boric acid-urea and ethyl athyl-hydrochloric acid were selected to study and explore the antioxidant performance and mechanism of natural graphite powder and natural graphite electrode samples before and after antioxidant treatment.Second, the application of scales graphite antioxidants.The main component of graphite antioxidants -high temperature -resistant nano -ceramic particles, loosening in the water solvents, forming a light red and nearly transparent liquid source. In -pores that penetrate into graphite materials, form a layer of antioxidant protective film on the surface o
