4. FAQ
Q: Which knid of payment terms can you accept?
A: We can accept 30% prepayment, 70% payment before shippment. LC is also accepted
- Q: Many of the performance of vanadium battery better than lead-acid batteries, but what are its disadvantages?
- On the use of super capacitor internal resistance is smaller, so the instantaneous release of the current can be greater. The super capacitor is not affected by the temperature, and all the chemical batteries are affected by temperature. When the ground temperature decreases, the internal resistance becomes larger. Supercapacitor is the pure physics principle, so it has longer life
- 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?
- 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 is the graphite plate machined?
- Graphite board has good characteristics such as good conductivity, high temperature resistance, acid resistance, alkali corrosion and easy processing. Therefore, it has been widely used in metallurgy, chemical industry, electrochemistry and other industries
- 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 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.
- Q: How to identify graphite impregnated PTFE and ordinary graphite?
- Graphite impregnated with PTFE should not react with it
