What are the anti-static measures
ESD protection Preventive measures taken to prevent personal electric shock, fire and explosion, failure and damage of electronic components caused by the accumulation of static electricity, and adverse effects on production. Its precautionary principles are mainly to suppress the generation of static electricity, accelerate the leakage of static electricity, and perform static neutralization. When people wear non-conductive shoes, charges can be generated and accumulated due to activities such as walking, and can reach a potential of the kilovolt level. The highest potential generated by walking on a blanket, undressing, etc. can reach 2450 volts. At this time, people touching other objects will cause spark discharge and electric shock. Anti-static measures in human activities mainly include wearing conductive shoes; working clothes and underwear do not use chemical fiber fabrics; wearing anti-static work clothes mixed with conductive fibers or treated with anti-static agents; work floor for conductive treatment. When two different objects come into contact with each other, a charge movement occurs at the interface, and positive and negative charges are arranged oppositely to form an electric double layer. If the objects are separated, an equal amount of charge of different polarity will be generated on each of the two objects. The principle to prevent this kind of static electricity is: Exclude as much as possible the main factors that generate static electricity (object characteristics, surface state, charging history, contact area and pressure, separation speed, etc.); Position as close as possible; make the contact area and pressure between objects 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 can generate static electricity due to friction during transportation. Therefore, it is necessary to restrict the flow rate and reduce the bending of the pipeline. Measures such as increasing the diameter and avoiding vibration. In addition to reducing the speed, pressure, friction and contact frequency, selecting appropriate materials and shapes, and increasing the conductivity, static protection can also take the following measures: ① grounding. ② Lap (or jump). ③ Shielding. ④ Use an antistatic agent on the insulator that can hardly leak static electricity to increase the conductivity and make it easy to leak static electricity. ⑤ Use spraying, watering and other methods to increase the ambient humidity and suppress the generation of static electricity. ⑥ Use a static eliminator to neutralize static electricity.
