Commonly used several effective static elimination methods
The most common method of shielding is to use electrostatic shielding bags and anti-static turnover boxes as areas to protect static sensitive components from static electricity during storage or transportation. Electrostatic shielding can weaken the influence of external static electricity on electronic components.
Second, electrostatic grounding is to connect some anti-static products to a ground wire. The ground wire is established by using a buried wire method. The resistance between the ground wire and the earth is <10Ω, which acts to discharge the charge that may accumulate on the conductor. The static electricity accumulated on the conductor is usually grounded by grounding. This method is economical and not only has a small investment but also has a long service life and can release static electricity.
The principle of the three static eliminator is to generate a large amount of positive and negative ions on the static eliminator, and then blow the ions to the static place by the wind, the static electricity will attract the opposite polarity ions and neutralize it, accumulate in the product. Or static electricity on the surface of the device is thus neutralized and eliminated. This method eliminates the static electricity speed and has high cost, and the maintenance cost of the static eliminator is high for a long time.
4. Antistatic agents can be used to scrub the surface of instruments and objects with static eliminators, which can quickly eliminate static electricity on the surface of objects. The role of the antistatic agent is to adsorb the moisture in the air on the surface of objects such as chemical fiber, rubber, plastic, etc., and increase the electrical conductivity. It can only be used to eliminate static electricity for a short period of time and easily fail.
5. Controlling the humidity of the environment can form a very thin water film on the surface of the object. The water film can dissolve the CO2 in the air, so that the surface resistivity is greatly reduced, and the static charge is not easy to accumulate. If the relative humidity drops to 40-50%, the static electricity is not easily dissipated, and it is possible to form a high potential. A common method of increasing the humidity of the air is to spray water into the air.
