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?: Any conductor has a resistance! It's just a different size!

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:How is the graphite plate machined?: The use of graphite plate (use) is different, determine its processing method.Generally for the following processing methods:Saw cutting graphite plate, rough machining.Machining, dimensional accuracy requirements of high products, such as cars, planes and so on.Impregnated resin, such as graphite board, into impermeable graphite board. Mainly used for lining.Large blocks are not impregnated with graphite slabs (bricks) for use in special chemical tanks.

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?: Bomb bomb (also known as soft graphite Soft Bomb), because it is not to kill the enemy troops for the purpose of name. It is also called Blackout Bomb because of its destructive power to the power supply system.

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
