Steelmaking using carburizing agent and cast iron using carburizing agent, and some other materials are also useful for adding to the carburizing agent, such as brake pads with additive, friction material. Recarburizer belongs to external steel and iron carbon materials. High quality carburizing agent additive is essential for production of high quality steel. Carburizing agent, there are many kinds of raw materials, production processes are different, wood carbon, carbon coal, coke, graphite, etc., in which various categories and a lot of small type. High quality carburizing agent generally refers to after graphite carburant, in under the condition of high temperature and carbon atoms arranged in graphite morphology, so called for graphitization. Graphite can reduce the content of impurities in the…
The isostatic pressing graphite technology is a kind of super high pressure hydraulic equipment,and its working principle is that products formed under the condition of equal pressure and high pressure in all directions and closed high-pressure container . The working principle of the isostatic pressure is Pascal's Law: "the pressure of the medium (liquid or gas) in the closed vessel can be transferred to all directions equally." Isostatic pressing technology has had 70 years of history, was used in the powder molding of powder metallurgy initially . In the past 20 years, the isostatic pressure technology has been widely used in many fields such as ceramic casting, atomic energy, tool manufacturing, plastics, super high-pressure sterilization of food and graphite, ceramics,…
The economic reference news reporter recently from authoritative sources was informed that including new materials planning, including a plurality of graphene industry support policies, is expected in the first half of the year, and gradually introduced. The core of these policies is promoting graphene industry key technology to achieve a breakthrough and rapid industrialization. Graphene industry will gradually form a lithium batteries for electric vehicles with graphene based electrode materials, marine engineering with graphene based anti-corrosive paint, flexible electronics with graphene films, the field of optoelectronic graphene based high performance thermal interface materials, including four industry clusters, the whole industry scale is expected to exceed billion yuan. The authorities revealed that the "new materials planning" will have special chapters on…
