We live in this planet, as a graphite producer, Beijing Great Wall should do something. A high-quality flake graphite product that closely resembles natural flake graphite can be made from steelmaking kish. Kish is a large-volume near-molten waste skimmed from the molten iron feed to a basic oxygen furnace, and consists of a mix of graphite (precipitated out of the supersaturated iron), lime-rich slag, and some iron. The iron is recycled on site, leaving a mixture of graphite and slag. The best recovery process uses hydraulic classification (which utilizes a flow of water to separate minerals by specific gravity: graphite is light and settles nearly last) to get a 70% graphite rough concentrate. Leaching this concentrate with hydrochloric acid gives…
Graphite rod were used as working electrodes to study the electrochemistry performance with the circulation voltammetry method.Graphite rod effects of the scanning velocity and times were investigated to examine the electrode's tolerance of voltage and electric current and the electric discharge performance. The experiment proves that the 5#D graphite rod electrode still shows good electrochemical properties.In order to inspect the cyclic properties,the 5#D graphite rod electrode was tested with the circulation voltammetry method.After 100 times of scanning,the current conservation rate of the 5#D graphite electrode was still as high as 95%.The experiment results show that the 5#D graphite rod electrode has a relatively better electrochemistry performance which is suitable for the VO2+/VO2+electrode's positive electrode material. A sheaf of the films…
Graphite reinforced gasket can also cut into the shape of complex gaskets such as water gauge pads, punching flange gasket and automotive diesel engine cylinder gasket. High strength gasket is pure cut gasket improvements inner coated metal foil, namely to maintain the excellent performance of the original gasket, and easy installation, removal, not damaged, but also to prevent the erosion of the gasket medium improve the pressure, and has good corrosion resistance, high / low temperature, good compression resilient and high strength gasket forms: ordinary type, stainless steel edging type. Material and Structure: Flexible graphite sheet material and the metal plate moved sprint composite molding. Temperature: -200 ° C ~ 600 ° C operating pressure: 20MPa main purposes: for a…
