2. In order to avoid static electricity, you can use small metal devices (such as keys) and cotton cloth to touch doors, door handles, faucets, chair backs, bed railings, etc. To eliminate static electricity, and then touch them with your hands.
3. Wear cotton underwear.
4. When getting ready to get off, hold the gear with your right hand, then touch the iron part below with your finger, then open the door, put your left hand on the iron part of the door, but don't let go of your left hand, and then let go of your right hand to get off. At this time, hold the door with your right hand to avoid electric shock.
We can take "prevention" and "release" measures to deal with static electricity. "Prevention", we should try to choose pure cotton products as fabrics for clothes and home decoration, and try to avoid using chemical fiber carpets and furniture with plastic as surface materials to prevent friction and electrification. Try to stay away from TV, refrigerator and other electrical appliances to prevent induction electrification.
"Discharge" is to increase humidity and make local static electricity easy to release. When you turn off the TV and leave the computer, wash your hands and face immediately, so that the electrostatic charge on the skin surface can be released in the water. Try to choose high moisturizing cosmetics in winter. Commonly used humidifier. Some people like to keep ornamental fish and daffodils indoors, which is also a good way to adjust indoor humidity.
Extended data:
Electrostatic phenomena include many natural examples, such as the attraction of plastic bags and hands, seemingly spontaneous barn explosion, the damage of electronic components in the manufacturing process, the working principle of photocopiers and so on. When the surface of an object touches other surfaces, charges will accumulate on the surface of the object and become static electricity.
Although the charge exchange is caused by the contact and separation of two surfaces, the effect of charge exchange will only be noticed when the resistance of one surface is high and the current is small. Because the charge will be trapped on that surface and stay there for a long time, enough to observe this effect for a period of time.
The electrostatic force of point charge interaction produces electrostatic phenomenon. Coulomb's law describes the physical properties of electrostatic force. In hydrogen atoms, the electrostatic force of the interaction between electrons and protons is much greater than gravity, and its order of magnitude is about 40 times that of gravity.
