Q:The graphite wrapping gasket prevents the film from being installed. Is it a thin one?: Graphite gasket: corrosion resistance, high temperature resistance; metal graphite spiral wound gasket: resistance to high pressure, corrosion resistant gasket is expensive metal graphite spiral wound gasket for semi metallic gasket recovery best gaskets high temperature metal graphite spiral wound, by V or W shaped steel strips with various fillers (graphite, asbestos PTFE), alternating wound together, the structure density can according to different requirements to lock force, and using internal and external steel ring to control its biggest compaction degree is not high, the flange gasket seal surface contact accuracy. The utility model is especially suitable for occasions with uneven load, easy loosening of joint force, periodic change of temperature and pressure, shock or vibration. It is the static seal of valve, pump, heat exchanger, tower, manhole, hand hole and so on. It is widely used in petrochemical, mechanical, electrical, metallurgy, shipbuilding, medical, nuclear and aerospace sectors.

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?: The super capacitor is a battery made by the principle of physics, and the two battery is mostly a chemical battery made by chemical principle. So the two are essentially two different things, one is physical charge transfer, and the other is chemical energy conversion into electrical energy.

Q:What is the difference between the wave tooth compound gasket and the graphite gasket?: Gaskets can be used directly without adhesive sealing layer, can achieve a good seal, gasket and tooth shaped combination compared with the compression resilience has better performance especially in the large size of the smoke, gas pipeline, low pressure, high temperature, flange or twist uneven, with sealing effect is more significant.

Q:How is the graphite plate machined?: The graphite plate has high purity graphite plate, electrode graphite plate and flexible graphite plate. Graphite: General specification and high strength, high density graphite side selection of high quality petroleum coke as raw materials, the use of advanced production technology and production equipment, the product has the characteristics of high density, compressive strength and flexural strength, low porosity, high ablation resistance, acid and alkali, for metallurgical furnace, resistance furnace, lining material, chemical equipment mechanical parts processing, mold shaped graphite material selection.

Q:Do you have a lot of plates with silica ink?: Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand". At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two, are six square crystal, the proportion of 3.20 to 3.25, the microhardness is 2840 ~ 3320kg/mm2.

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
