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 is a metal gasket, usually with precision lathe or milling machine into a waveform shaped trench concentric in two face machining flat metal gasket, the upper and lower sides of the tooth tip staggered, the compression spring has better performance, and the other is due to the sealing surface contact several concentric circles line contact, therefore has the labyrinth seal, according to medium and different working conditions, can choose flexible graphite, PTFE, non asbestos or some other soft metal, pasted on the two surface of the gasket, the soft cover seal and the advantages of the strength of the metal, good elasticity, in order to achieve a better sealing effect in most cases, we recommend graphite as a sealing layer, when the medium to produce graphite reaction or clean environment requirements when we suggest that the selection of the newly launched expanded PTFE excellent performance for paste Layer, metal wave tooth composite gasket generally does not need a lot of pressing force, you can achieve the sealing effect.

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 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: 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: 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: 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: How to identify graphite impregnated PTFE and ordinary graphite?: Prior to purchase, use a strong nitric acid test to stimulate the formation of gas.
