Types and prices of scales graphite powder

There are many types of scales graphite powder. Scales graphite powder is a major type of graphite powder. Different types of scale graphite powder. The price of scales graphite powder is different. The scale graphite powder can be divided into high carbon scales graphite powder according to the amount of carbon. Mid -carbon scales graphite and low -carbon scales graphite powder. The higher carbon -containing scale graphite powder, the larger the scale of the scale graphite powder is industrial.The application range of high -carbon scales graphite powder is relatively wide in industry. High -carbon scales graphite powder uses high -quality natural scales graphite as raw materials. The carbon content of high -quality natural scales is very high. Increase the carbon content of scales graphite powder, and under the same factors such as granularity of high -carbon scales graphite powder, the price of high carbon scales graphite powder is higher than the price of carbon scales graphite, lo

How is expanded graphite produced?

Due to the fact that graphite is a non-polar material, it is difficult to intercalate with small polar organic or inorganic acids alone, so oxidants are usually required. The chemical oxidation method generally involves soaking natural flake graphite in a solution of oxidants and intercalators. Under the action of strong oxidants, graphite is oxidized, causing the neutral network of planar macromolecules in the graphite layer to become positively charged planar macromolecules. Due to the extrusion effect of isotropic positive charges between positively charged planar macromolecules, the spacing between graphite layers increases, and the intercalation agent is inserted between the graphite layers to form expanded graphite.Expanded graphite will rapidly shrink when heated at high temperatures, with shrinkage times reaching tens to hundreds or even thousands of times. The apparent volume of contracted graphite reaches 250-300 milliliters/gram or more. The shrunken graphite is in the shap

Method of making low -density puffed graphite blocks with flexible graphite

In recent years, various types of low -density carbon graphite materials have been actively researched, including carbon (graphite) foam made of asphalt or polymer resin, as well as using high repetition pulse laser to abolish carbon materials The carbon nano foam formed. Granny Gygm is also a low -density carbon graphite material. Due to the simple preparation process and low production cost, it is convenient for large -scale industrialized production. In recent years, the research on expandable graphite has continued to deepen. The following editor of Jinhui Graphite Company introduced the method of soaking flexible graphite in the concentrated acid into a low -density puffed graphite block:The insect shape and weak macro structure of puffed graphite restrict their application. If it can be made into a stable -swollen graphite block, it will be conducive to puffed graphite to play its role as adsorption, heat insulation, heat conduction and other functional materials. The flame reta
