Employees must be equipped with anti-static equipment in winter

The cold winter air brought cold and dryness, but also brought a naughty little "devil" - static electricity. In order to prevent static electricity from harming the human body and endangering the work, it is a must for enterprises to properly purchase and wear anti-static shoes, anti-static clothing and anti-static caps. Here we need to give a detailed explanation of the causes and hazards of static electricity and preventive measures.

In the dry cold winter, the temperature is relatively low, the saturated vapor pressure of the air is already relatively low, and in addition to the dry feeling, the content of water vapor in the air is even lower. The static electricity generated in this way is not easily guided by the water vapor in the air and is relatively easy to accumulate. Therefore, static electricity is more likely to occur.

Electrostatic phenomena are considered to be the result of contact separation. When an object contacts and separates, there is a charge transfer, even if it is a liquid.

Static electricity is a substance. When low-humidity weather occurs, chemical fiber textures such as underwear, carpets, cushions, and wallpaper can be electrostatically charged. In addition, the use of household appliances will also have an electrostatic effect or static electricity on the housing.

The harm of static electricity:

1. The first hazard of static electricity: from the interaction of charged bodies.

When the aircraft fuses with air, moisture, dust, etc., it will cause the aircraft to become energized. If no measures are taken, it will seriously interfere with the normal operation of the aircraft's radio equipment, turning the aircraft into tweezers and tweezers; in the printing plant, the paper sheet The static electricity between them will bind the sheets together, making it difficult to separate them and causing trouble for the printing; in the pharmaceutical factory. Due to the electrostatic attraction of dust, the purity of the drug may not be up to the standard; when the television is put on the screen, static electricity on the surface of the screen tends to attract dust and oil, forming a layer of dust film, which reduces the clarity and brightness of the image; it is on the blended clothes. The dust that is common but not easy to shoot is also the ghost of static electricity. In drums, leather, plastics, chemical fabrics/films and other assembly lines, due to high material insulation, fast operation, surface charge is not easy to dissipate, the static electrode is high, when the operator touches there will be a touch inductance, and more between the material layers Breakdown, affect product quality. In the electronics industry, IC, LCD, LED, and other fine assembly lines, according to statistics, due to static electricity to the electronic device manufacturing industry, will cause more than two billion US dollars in losses each year!

2. The second major hazard of static electricity: It is possible that an electrostatic spark may ignite certain flammable objects and cause an explosion.

On dark nights, when we take off nylon and woolen clothes, we will emit sparks and "buzz" sounds, which are basically harmless to the human body. However, on the operating table, in addition to EDM will cause an explosion of anaesthetic, injury to doctors and patients; in coal mines, it will cause gas explosions, will lead to worker deaths and injuries, mines scrapped. The body's long-term exposure to electrostatic radiation can cause anxiety, headaches, chest tightness, difficulty breathing, and coughing. In the family life, static electricity not only has chemical fiber clothing, but also has static electricity at the foot of carpets, daily plastics, bright paint and furniture, and various household appliances. Static electricity can absorb a large amount of dust in the air, and the more charged, the more dust is absorbed. The more the number, the dust often contains a variety of toxic substances and pathogens, light to stimulate the skin, affect the skin's luster and delicate, it makes the skin from sores, more serious will lead to bronchial asthma and arrhythmia And other illnesses.

In short, electrostatic hazards result from the use of electricity and static sparks, and the most serious electrostatic discharges from electrostatic hazards cause flammable materials to catch fire and explode. In this way, static electricity prevention and protection become necessary, and preventative measures taken to prevent electric shock, fire and explosion, electronic device failure and damage caused by static electricity accumulation, and adverse effects on production. The precautionary principle is mainly to suppress the generation of static electricity, accelerate the leakage of static electricity, carry out electrostatic neutralization, and so on. When people wear non-conductive shoes, due to walking and other activities will generate, accumulate charge, and can reach the potential of kilovolts. Walking on a blanket, stripping, etc., generates the highest potential up to 2450 volts. At this point, the human touches other objects and creates a spark discharge and receives an electric shock. Anti-static measures for human activities mainly include wearing anti-static shoes; uniforms and underwear do not use chemical fiber fabrics; wear anti-static overalls with conductive fibers or anti-static agents;

Second, in the daily life and work, there are mainly the following static prevention measures:

1, try not to put or put less household appliances in the bedroom. In this way, it is possible to prevent the human body and the electric appliance from generating static electricity at a short distance and touching the static electricity. It is better to watch television at a distance of 2 to 3 meters from the television.

2, use the "third party" to eliminate static electricity. To avoid static electricity hits, small metal devices (such as keys), cotton rags, etc. can be used to eliminate static electricity by first touching the doors, door handles, faucets, backs, and bed rails that can cause static electricity.

3, with natural fabrics. Use natural fabrics such as cotton, hemp, and silk as far as possible for underwear, sheets, quilts, etc. Try not to wear or wear home textile articles and clothing of chemical fiber texture.

4, with a wooden comb, hair moisturizer. Hair combs are used on the hair and conditioners are used when shampooing to eliminate static electricity. When the hair can not be combed, the comb is immersed in water, and after the static electricity is eliminated, it can be combed at will.

5, maintain the indoor temperature. Static electricity is not easy to produce. It is best to use a humidifier in the winter season. Flowers and grass can also be placed to avoid static electricity. When the indoor air humidity is lower than 30%, static electricity is generated by friction. If the temperature is increased to 45%, static electricity is hardly generated. Therefore, when low-humidity weather occurs, you may wish to sprinkle some water at home, inconveniently dampen the floor, place two or four pots of clean water, which can also increase the indoor air humidity.

6, the use of space-proof static materials such as floors, walls, ceilings.

7, eat more vegetables, fruits, yogurt, drink plenty of water, while adding calcium and vitamin C, in order to reduce the impact of static electricity.

8, for the elderly, children, static sensitive, can not find out the cause of heart disease, neurasthenia and mental patients and other recommendations in winter wear cotton underwear, underwear, in order to reduce the adverse effects of static electricity on people.

9, bathe diligently, frequently change clothes, can effectively eliminate the electrostatic charge of the body surface area.

10. Barefoot is conducive to electrostatic discharge on the surface. Therefore, don’t let go of barefoot opportunities when you’re casual.

11. When you get off the train, use your right hand to hold the file, then use your fingers to touch the iron underneath. Then open the door, place your left hand on the door with iron, but don't loosen your left hand, then let go of your right hand. Car, when you grab the door again with your right hand, you won't be charged.
