The two sides of static electricity

The hazards of static electricity are many, including fire or explosion, electric shock, and interference with production.

1. Fire or explosion: fire and explosion are particularly harmful to static electricity. Although the electrostatic power is not large, but because of its high voltage easy to discharge, electrostatic spark. Fires may be caused by electrostatic sparks in workplaces with flammable liquids, such as oil loading sites; In places with explosive dust or explosive gases and vapors, such as pulverized coal, flour, aluminum powder and hydrogen, explosion may be caused by electrostatic sparks.

2, electric shock: electrostatic shock may occur in the human body close to the electrostatic material, may also occur in the electrostatic charge of the human body close to the grounding body, at the moment the human body with static electricity can be as high as ten thousand volts. The severity of electrostatic shock is related to the energy stored on the electrostatic body. The higher the energy, the more severe the electric shock. The larger the capacitor or the higher the voltage, the more severe the electric shock. The electrostatic energy produced during the manufacturing process is small, so the resulting electric shock is not directly fatal. However, the human body may fall or fall due to the electric shock, causing a secondary accident.

3, hinder production: static electricity will hinder production, or reduce product quality. In the textile industry, static electricity makes the fiber tangle, adsorb dust, and reduce the quality of textiles; In the printing industry, static electricity makes the paper line uneven, can not be separated, affect the printing speed and printing quality; In the photographic film industry, electrostatic sparks make the film sensitive, reduce the quality of the film; In the powder processing industry, static electricity makes the powder adsorbed on the equipment, affecting the filtration and transportation of the powder; Static electricity may also cause misoperation of electronic components; Jamming radio communications, etc.

However, every coin has two sides. For the hidden troublemaker of static electricity. As long as the understanding of its temper, foster strengths and circumvent weaknesses, can also let it serve the human. For example, electrostatic printing, electrostatic spraying, electrostatic flocking, electrostatic dust removal and port separation technology, has been widely used in industrial production and life. Static electricity has also been used to desalinate seawater, spray pesticides, cloud seeding, cryogenic freezing, and even installed electrostatic devices such as electrostatic feeders on spacecraft.

Static electricity on the body

When the weather is very dry, brush your hair in the morning, the hair will often float up with the comb, more and more messy; When we meet and shake hands, we will be electrocuted as soon as our fingers touch. After walking on the floor in shoes with good insulation performance, when to open the door, the metal doorknob flashlight, fingertip like a stabbing pain; When I undressed at night, I heard a crackling sound. These phenomena are the result of electrostatic discharge of the body. Do you know what static electricity does to the body? Its harm to the human body can not be underestimated!

The harm of static electricity to pregnant women

Persistent static electricity can cause the pH of human blood to rise, the excretion of calcium in urine to increase, blood calcium to decrease, and the health of pregnant women is particularly harmful. Static electricity can cause the level of progesterone in the body of pregnant women to fall, so that they are prone to fatigue, irritability and headache, so it is necessary to take appropriate precautions.

The harm of static electricity to baby

First of all, it will increase the alkaline concentration of blood, and reduce calcium, which is in the growth period of infants and young children is really a big taboo. In addition, electrostatic adsorption of a large number of dust contains a variety of viruses, bacteria and harmful substances, they will make the baby's skin inflammation, weak resistance of the baby may even cause bronchitis, asthma and arrhythmia and so on! To eliminate ESD damage, you can prevent and release ESD damage. The following describes several methods to prevent ESD damage.

Prevention method:

1. To prevent static electricity from hair, use hair conditioner as far as possible after cleaning hair to prevent hair dryness, and try to use wood or horny comb to comb hair. When using a plastic comb, it can be dipped in water before combing.

2. In dry season, try to wear pure cotton clothes, with natural textile sheets, quilt cover, try not to wear chemical fiber clothing, so as to prevent friction electricity. As far as possible away from the television, refrigerator and other electrical appliances, can prevent the induction of electricity.

3. To avoid static electricity, use small metal devices such as keys to touch the door, faucet, chair back, and other metal objects, eliminate static electricity, and then touch with your hand.

4. Frequent bathing and hand washing can release the accumulated static electricity on the human body surface in the water. Indoor barefoot walking can also release the accumulated static electricity on the body surface into the floor.

5. Use a humidifier, or put a cup of water and a wet towel on the heater to increase the humidity in the room. Keeping ornamental fish and placing some green plants also regulate indoor humidity. This reduces the triboelectric condition.

6. Diet, to eat more vegetables, fruits, yogurt and other acidic food; Drink more water and supplement calcium and vitamin C to maintain the normal electrolyte balance and reduce static electricity.

Static electricity on an airplane

Aircraft in flight and the air and cloud in the tiny hail crystal friction, so that the aircraft with a large number of electrostatic charge, accumulated to a certain extent will affect the aircraft radio communication. If not guided during the landing process, when the local crew approached the fuselage, sparks would be generated between the person and the aircraft, and in severe cases, the person could be knocked down.

Prevention method:

1. Install a discharge brush on the wing tip and tail of the aircraft, so that the static electricity generated by the aircraft can be released continuously, so that the aircraft can fly safely.

2. Each connection part of the machine is equipped with a ground wire, the various parts are connected as a whole, can reduce the potential difference of the connection point, prevent spark discharge.

3. Using conductive tires, the plane causes static electricity to flow into the ground when it lands.

Part/04

Static electricity from cars

Car static electricity can be divided into two categories: one is the static electricity of the car itself, (such as the friction of the seat cover and the seat cushion and the electricity) so that the passengers feel electric shock or bring some other inconvenience;

The second is the static electricity of tanker trucks, which are specially used to carry liquid fuels such as gasoline or diesel. In the process of oil filling and transportation, if the charge brought by the friction and impact of fuel oil and oil tank is not guided away in time, accumulated to a certain extent, electric sparks will be generated, causing an explosion.

Prevention method:

1. Friction of fiber is an important source of static electricity of cars, so when choosing items such as car seat cover, seat cushion and foot cushion, it is recommended to use genuine leather and pure cotton products; Pay attention to the choice of car wax, according to the characteristics of the car to choose different types of car wax; Or use some ESD electronic devices to export the static electricity in time.

2. The method of preventing the static electricity of the tank truck is generally installed under the car with a chain dragged on the ground, and the static electricity is imported into the earth.

The picture

Reze antistatic masterbatch, compared with the previous directly added liquid, powder or paste antistatic agent is easier to disperse and achieve the ideal antistatic effect. The antistatic masterbatch is resistant to high temperature and has good performance. It will not decompose during spinning or injection molding. The dosage is low, the effect is quick and the effect is lasting. According to the processing characteristics of different resins, different efficient antistatic agents are selected to meet the requirements of various processing industries.
