Q:The graphite wrapping gasket prevents the film from being installed. Is it a thin one?: The lining materials are made of different metal sheets. Type optional, no hemming, inner edge, edge, inner edge. Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc.

Q:Why does graphite conduct resistance?: First of all, in addition to superconductors, any conductor has a resistance, and then the graphite resistance is based on the anisotropy of graphite and different, and then the degree of graphitization also determines the size of the graphite resistor.

Q:Many of the performance of vanadium battery better than lead-acid batteries, but what are its disadvantages?: There are two main technical problems, the existence of the first vanadium vanadium battery, battery anode in liquid pentavalent vanadium in static or temperature higher than 45 degrees Celsius conditions to the precipitation of five of two vanadium precipitation, the precipitation plug flow, coated carbon fiber, the deterioration of stack performance, until the stack is discarded, and power in a long time during the operation of reactor temperature of electrolyte can easily exceed 45 degrees celsius. Second, the graphite plate to be positive liquid etching, if the user properly operated, the graphite plate can use two years, if the user improperly, a charge can let the graphite plate completely etching, stack can only be scrapped. In normal use, every two months should be maintained by professionals, this high frequency maintenance costly and laborious.

Q:What is the difference between the wave tooth compound gasket and the graphite gasket?: Special conditions such as extremely high temperature, strong corrosion and so on require special materials metal wave gear composite gasket, we can also produce some of the following special material requirements:321316TI, 309347410, 304L stainless steel, dual phase steel, Monel (220531803) MONEL (400), INCONEL (600625), nickel indium, INCOLOY (800825), Hastelloy HASTELLO (B2, C276), titanium (T2) and other special stainless steel or alloy materials.Graphite gasket made of pure graphite or metal plate (tooth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as thermal stability, self lubrication, corrosion resistance, not aging, not fragile, the use of long-term stability in the harsh working conditions, rarely need maintenance. The lining materials are made of different metal sheets. The type is optional, without hemming, inner wrapping, outer wrapping, inner and outer wrapping. Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..Graphite gasket is mainly used in various industrial pipe flanges, heat exchangers, valves, etc., and liquid level gauge, special flange on the level.Graphite gasket to stone line as the material, by weaving and shaping. Graphite gasket suitable for high temperature, high pressure, strong corrosive medium work all kinds of valves, pumps, reactors and other equipment packing box sealed.

Q:How is the graphite plate machined?: Processing is the process of converting raw materials and semi-finished products into target requirements through certain processes and methods.

Q:Do you have a lot of plates with silica ink?: Graphite (siliconized) is a kind of composite material which is coated with silicon carbide layer on the surface of graphite material. The hardness of silicified graphite is actually the hardness of SiC, which is only inferior to that of diamond, boron nitride and boron carbide, which is higher than that of tungsten carbide and three aluminium oxide two. Silicified graphite can be used as bearings of pumps such as phosphoric acid, phosphorous amine and hydrofluoric acid. In addition, the semiconductor industry, as a silicon epitaxial heating film substrate and clamp, and manufacturing artificial joints, artificial heart valve, artificial tooth root and so on.

Q:Why can graphite be used to power the appliance?: The bomb is used after special treatment of graphite carbon material, each carbon filament diameter is very small, only a few thousand of CM, therefore, can be in the high altitude long time floating. Because of its after grinding fluid energy is made, and after chemical cleaning, thus greatly improve the conductivity of the carbon filament. Carbon filament is not sticky, but can be attached to any surface. It is detonated by explosions or gunpowder, scattered in enemy positions, and destroyed enemy air defenses and power generation equipment. Carbon filament into electronic devices, internal cooling pipes and control system of the black box. Its warheads are destructive to stop on the runway including aircraft, electronic equipment, power plant power grid and all.

Q:How to identify graphite impregnated PTFE and ordinary graphite?: Carbon can be oxidized by concentrated nitric acid to form nitrogen dioxide and carbon dioxide
