How to effectively prevent the generation of static electricity
Static electricity is not generated for no reason, it also has certain factors. We can prevent the generation of static electricity from the following aspects:
The main factors of static electricity are: the characteristics of objects, surface conditions, charging history, contact area and pressure, separation speed, etc. should be eliminated as much as possible; the positions of the objects in contact with each other in the charging sequence should be as close as possible; the contact area and pressure between objects It should be small, the temperature should be low, the number of contacts should be small, the separation speed should be small, and the contact state should not change sharply. Powder, liquid and gas will generate static electricity due to friction during transportation. Therefore, measures should be taken to limit the flow rate and reduce pipe bending. Increase the diameter to avoid vibration.
In addition to reducing speed, reducing friction and contact frequency, selecting appropriate materials and shapes, and increasing conductivity, the following measures can be taken for electrostatic protection of static eliminators:
① Grounding.
② Overlap (or jumper).
③ Shield.
④ For insulators that are not easy to leak static electricity, use antistatic agents to increase the conductivity and make them easy to leak static electricity.
⑤ Spray and sprinkle water to increase humidity and suppress static electricity.
⑥ Use a static eliminator to neutralize static electricity. Static Eliminator
