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?: 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?: 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: Why does graphite conduct resistance?: Resistors are available, some are large, others are smallOf course, in addition to superconductivity

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?: 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: How to identify graphite impregnated PTFE and ordinary graphite?: Graphite impregnated with PTFE should not react with it
