Graphite carbon plate adopts high quality graphite carbon material, and the organic compound with strong acid resistance is added. By high pressure molding, vacuum impregnation, high temperature heat treatment The process is refined, has the special acid resistance and the temperature resistance performance, is the chemical industry phosphoric acid reaction trough, the phosphoric acid storage tank and so on equipment ideal lining material. Excellent corrosion resistance Products using carbon graphite material quality, adding organic compound with strong acid, effectively reducing the product porosity increases, the bulk density of the products, so the product has strong corrosion resistance and excellent wear resistance. Stable performance, strong durability The product is made of high strength organic glue as binder, and the high and…
High purity graphite: graphite content of more than 99.9% of graphite called high pure graphite. Is an ideal inorganic non metal crucible boat, crystal furnace heater, EDM graphite, sintering mold, tube anode, metal coating, semiconductor technology with graphite crucible, electron tube, thyratron and mercury arc rectifier with graphite anode, grid etc.. High purity graphite has the advantages of small resistance coefficient, high temperature resistance, corrosion resistance, oxidation resistance, good thermal shock resistance, electrical conductivity, thermal conductivity, small coefficient of expansion, self lubrication, easy machining precision and so on. 1) high temperature resistant graphite melting point of 3850 - 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is…
At present, the domestic production of graphite felt is mainly used to make thermal insulation material, and its conductivity and electrochemical activity can not meet the requirements of the use of battery electrode materials, therefore, it needs surface treatment on the for graphite felt .Commonly used surface treatment methods include heat treatment, acid treatment and electrochemical oxidation treatment. The operation of heat treatment in air atmosphere, and the heat treatment after carbon fiber conductive ability has been improved, but there is no deep research on revealing fiber structure changes and conductive ability of the report. The surface morphology and structure of carbon fiber felt changed before and after heat treatment, and the conductivity of the carbon fiber felt was also…
