Two different objects can be friction with each other, even dry air and clothing friction will be charged. Friction of electricity in the conductive objects can be quickly flow loss, and in the non-conductive insulators such as chemical fibers, woolen fabrics and other objects on the static formation of static electricity, and gathered, when a certain voltage is reached on the phenomenon of discharge, loud noises and sparks. In short, dry air, water molecules and poor conductivity is the condition of static electricity. Static electricity has a lot of hazards, such as static electricity can produce interference with automatic instruments and electronic components; in the chemical industry, textile sector due to chemical fiber discharges generated by the sparks, can be flammable gases (acetylene, etc.), flammable liquid vapors (gasoline vapors, etc.) to detonate, resulting in fires; in the sky, airplanes and air, water, dust and other friction charged, can be a serious drying of aircraft and the plane's radio communications and make the plane disoriented; in the pharmaceutical industry, the static electricity adsorption In pharmaceutical factories, electrostatic adsorption of dust and make drugs impure, affecting the quality; in sterile and dust-free biochemical laboratories and hospitals, electrostatic adsorption of dust also has a negative impact; in the printing press, due to electrostatic electricity can make the paper bonded together with each other, it is difficult to separate, resulting in difficulties in printing; in the television, the fluorescent screen surface of the static electricity adsorption of dust and grease and the formation of a layer of dust film, so that the clarity of the TV image and the brightness of the greatly reduced; in the coal mines, electrostatic electricity can trigger a In coal mines, static electricity can cause gas explosions, which can lead to serious injuries and mine accidents.
According to tests, static electricity is also harmful to the human body to a certain extent. When the static voltage reaches 2,000 volts, the fingers will feel it; more than 3,000 volts when there is a spark appeared, the fingers and have a needle prick like pain; more than 7,000 volts, people will have a sense of electric shock. In daily life, the static voltage can sometimes be as high as tens of thousands of volts, but due to the friction of the time is very short, the flow of electricity generated is also very small, and thus generally will not cause life-threatening to the human body. However, in the medical operating table, electrostatic sparks can cause the explosion of anesthetic agents, thus harming the medical staff and patients, must be noted. Also, the electrostatic adsorption of a large number of dust containing a variety of viruses, bacteria and harmful substances, harmful to human health, serious electrostatic phenomenon can make the human skin spot inflammation, but also make people irritable, dizziness, chest tightness, nasopharyngeal discomfort, and can even trigger bronchitis, asthma and arrhythmia.
Static electricity has a lot of harm to people, but there are a lot of benefits, such as people have been using electrostatic technology used in dust removal, printing, spraying, flocking, sorting, desalination of seawater, spraying pesticides, artificial rainfall, low-temperature refrigeration, spaceships, such as feeding the industrial and agricultural production and life. Eliminate static hazards is the easiest way to introduce static electricity into the ground, such as the use of wires to make the equipment grounded; in the aircraft wingtip and tail installation of discharge brush, aircraft landing gear on the use of grounded tires and grounding lines, etc.; tanker trucks tied to the end of a grounding chain; in the chemical industry production, storage, transportation sector, is strictly prohibited the use of synthetic fabrics, staff are strictly prohibited from wearing synthetic work clothes, etc.; in daily life, you can also use some simple Measures to eliminate static electricity, such as underwear, was in, sheets, covers, etc. to use cotton fabrics as well, try not to use chemical fiber products; indoor home can often sprinkle, spray humidification, etc. to eliminate static electricity.
How to prevent static electricity in winter?
I am often struck by static electricity nerves, a see metal things on the balking, even wash your hands will be inside the water pipe out of the water to the electricity, I am really about to faint Que. I believe that many people also have the same experience. And try not to wear flowery clothes.
2, in order to avoid static electricity hit, available small metal devices (such as keys), cotton rags and other first touch the door, door handle, faucet, chair backs, bed rails, etc. to eliminate static electricity, and then touch the hand.
3, wear cotton underwear.
4, ready to get off the car, use the right hand to hold the gear, and then use your fingers to touch the part of the iron below, and then open the door, put your left hand on the door has iron position, but the left hand don't let go ，，，， and then let go of the right hand, get off the car, at this time, you then use your right hand to grasp the door won't be electrified ~~. Next, force a close,, get it done ~~
5, against static electricity, we can take "defense" and "put" two hands. "Prevention", we should try to use cotton products as clothing and home furnishings fabrics, try to avoid the use of chemical fiber carpets and plastic as the surface material of the furniture, in order to prevent friction electricity. As far away as possible, such as televisions, refrigerators and other electrical appliances, in order to prevent the induction of electricity. "Discharge", is to increase humidity, so that the local static electricity can be easily released. When you turn off the TV, leave the computer, you should immediately wash your hands and face, so that the static charge on the surface of the skin in the water to release off. In winter, try to use highly moisturizing cosmetics. Commonly use a humidifier. Some people like to keep ornamental fish and daffodils indoors is also a good way to regulate indoor humidity.
In addition, recommended to you an economical and practical method of humidification: placed under the heater, a pot of water, with an old towel (or absorbent cloth), one end of the water, one end of the ride on the heater, so that a day and night can be evaporated into the house about three liters of water. If you do this for each heater, the whole room will feel moist and pleasant. You may wish to try it.
6, diligent bathing, change clothes, can effectively eliminate the static electricity accumulated on the surface of the body.
When the hair can not be combed service, the comb will be immersed in water, such as static electricity after the elimination, you can feel free to comb. Try to use a moisturizer or conditioner when washing your hair.
Barefoot is good for releasing the static electricity accumulated on the body surface. So don't miss every opportunity to go barefoot when you're relaxing.
Eat more vegetables, fruits, yogurt and other acidic foods, drink more water, as well as supplement calcium and vitamin C to reduce the effects of static electricity.
