Special graphite

Time：2023.05.17Browse：1: Share:

Special graphite mainly refers to high -strength, high -density, high -purity graphite products (referred to as three high graphite). Three high graphite can be divided into three types: thick particle structure, fine particle structure and special particles structure in terms of material and organizational structure. It is divided from the forming method. Three categories, in addition, vibration molding can also be used to produce special graphite. High -quality special graphite is different from the same -sex graphite.

Not all special graphite must achieve the same high, high -strength, and high -purity indicators. Special graphite used on different occasions has specific strength and density requirements, that is, the strength and density indicators are different. Many special graphite does not need to reach high purity, and the gray score is not the main quality indicator. Some special graphite does not require high and dense but high -purity. Some special graphite, such as electro -spark processing, uses different processing processes and processing objects. Fine particles structure graphite or special particles structure graphite with different physical and chemical indicators.

One article understands natural scales graphite surface modification methods

Natural 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

Graphite Product Materials advantage

Graphite products (including graphite rods, graphite products, graphite blocks, graphite boards, graphite carbon pipes, graphite rings) are important strategic resources. Graphite is a degeneration of carbon substances, which is most common in Dali, sliced rocks, or hemp rocks. The coal seam can form graphite through the thermal deterioration, while a small amount of graphite is a native mineral of fire rock.The industrial graphite ore is divided into two categories: crystal (scale) graphite ore and steady crystal (earth -shaped) graphite ore. Crystal graphite ore can be divided into two types: scale -like and dense. Chinese graphite ore is the type of scales -like crystal, followed by hidden crystal type, and dense crystal graphite is only seen in individual mining plants such as Tocobra, Xinjiang.Due to its special structure, graphite products are resistant to high temperature resistance, heat shock resistance, conductivity, lubrication, chemical stability, and plasticity.

What factors are influenced and gray -testing of scales graphite creep

1. The creep of scales graphite increases with the increase of temperature and stress time. 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.
