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 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: Why can graphite be used to power the appliance?
- The general high voltage transmission lines are exposed. Graphite is a conductor, after spraying directly like cobweb winding between the transmission lines, causing a short circuit. Thus the destruction of power facilities, leading to the city power.
- 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?
- Any conductor has a resistance! It's just a different size!
- 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
