What are the hazards of static electricity

There are many hazards of static electricity, the first hazard comes from the interaction of charged bodies. In the aircraft body and air, water, dust and other particles will make the aircraft friction charged, if not take measures, will seriously interfere with the normal work of the aircraft radio equipment; in the printing press, the static electricity between the pages of the paper will make the paper pages bonded together, it is difficult to separate, to the printing trouble; in the pharmaceutical factory, due to static electricity to attract dust, will make the drugs do not meet the standard purity; in the TV screen surface of the electrostatic discharge Easily adsorbed dust and oil, the formation of a layer of dusty film, so that the clarity and brightness of the image is reduced; on the blended clothes on the common and not easy to shoot off the dust, but also electrostatic ghosts. The second major hazard of static electricity is the possibility of explosion due to electrostatic spark ignition of certain flammable objects. Dark night, people take off nylon, woolen clothes, will send sparks and "bla bla" sound, which is basically harmless to the human body. But on the operating table, electric sparks will cause anesthetic explosion, injuring doctors and patients; in coal mines, it will cause gas explosions, which will lead to death and injury to workers, mine scrapping. In short, electrostatic hazards caused by electricity and electrostatic sparks, electrostatic hazards in the most serious electrostatic discharge caused by combustible fire and explosion. People often say, prevention is better than cure, measures to prevent the generation of static electricity are generally to reduce the flow rate and flow, transform the process of strong electricity, the use of equipment and materials with less electricity. The simplest and most reliable way is to use the wire to ground the equipment, so that the charge can be introduced into the earth to avoid static electricity accumulation. Attentive passengers will probably find; in the aircraft on both sides of the wingtip and the tail of the aircraft are equipped with discharge brush, aircraft landing, in order to prevent passengers from being electrocuted when the plane, the aircraft landing gear on the majority of the use of special grounding tires or grounding wire; to discharge the aircraft in the air generated by the static charge. We also often see the tail end of the tanker truck drag a chain, which is the car's grounding wire. Properly increasing the humidity of the work environment so that the charge is ready to be discharged can also be effective in eliminating static electricity. It is not easy to do a good static test in humid weather, this is the reason. Antistatic agents studied by researchers, on the other hand, do a good job of eliminating static electricity inside insulators. However, there are two sides to everything. For static electricity this hidden troublemaker. As long as you feel through its temperament, to capitalize on its strengths and avoid its weaknesses, but also to make it serve mankind. For example, electrostatic printing, electrostatic spraying, electrostatic flocking, electrostatic dust removal and electrostatic sorting technology has been widely used in industrial production and life. Static electricity has also begun to desalinate seawater, spraying pesticides, artificial rainfall, low-temperature refrigeration and many other aspects of the show, and even in the spaceships are also installed on the electrostatic charger and other electrostatic devices.

The accumulation of static electricity is inevitable. Static electricity will burn the human skin when serious, a variety of electrical appliances electromagnetic waves and harmful rays in excess will interfere with the human endocrine system. With the improvement of people's living standards, as well as environmental protection awareness of the enhancement of the anti-static metal fabric applications are also increasingly expanding, anti-static metal fabric clothing such as vocational clothing, workwear, protective clothing popularity, anti-static metal fabric has also emerged as a star product in the fabric market. The latest market dynamics show that many developed countries have been used in the field of home textile products, such as bed cover, paved, cushion are used on the anti-static metal fabric. Demand is very large, orders are constantly. However, the manufacturer has to have three conditions. First, the product should meet the requirements of the importer's indicators. Second, the post-processing to pass. Third, to be woven on a wide loom. Most of the orders are from Japan and Europe. The domestic northern market also has some sales. There is no doubt that the market prospect of anti-static metal cloth is very broad.

Hazards in industry

The generation of static electricity is unavoidable in industrial production, and the hazards caused by it can be mainly attributed to the following two mechanisms:

One of them: the hazards caused by electrostatic discharge (ESD):

(1) cause malfunctions or malfunctions of electronic equipment, resulting in electromagnetic interference.

(2) Breakdown of integrated circuits and precision electronic components, or promote the aging of components, reducing the production yield.

(3) High-voltage electrostatic discharge causes electric shock, endangering personal safety.

(4) In more flammable and explosive products or dust, oil mist in the production site is very easy to cause explosions and fires.

The second, electrostatic attraction (ESA) caused by the hazards:

(1) electronics industry: adsorption of dust, resulting in integrated circuits and semiconductor components of the pollution, greatly reducing the yield.

(2) film and plastic industry: so that the film or film rewinding uneven; film, CD plastic disk stained with dust, affecting the quality.

(3) paper printing industry: paper winding is not aligned, overprinting is not allowed, the absorption of dirt is serious, and even paper adhesion, affecting production.

(4) textile industry: cause root silk fluttering, tangled flowers broken head, yarn tangled and other hazards.

The hazards of electrostatic **** witnessed, people have begun to implement various degrees of anti-static measures and projects. However, it is important to recognize that the perfect and effective anti-static project in accordance with the actual situation of different enterprises and different operating objects, the development of appropriate countermeasures. Anti-static measures should be systematic and comprehensive, otherwise, it may be twice the effort, and even cause destructive counterproductive.

Harm to pregnant women

Persistent static electricity can cause an increase in the pH value of human blood, increased calcium excretion in the urine, decreased blood calcium, the most harmful effects on maternal health, static electricity can lead to a decrease in the level of progesterone in the body of the pregnant women, so that they are prone to fatigue, irritability and headache, etc., so there is a need to take appropriate precautions.

Static electricity on the baby's harm

First of all, it will make the blood alkaline concentration increased, and calcium decreased, which is in the growth period of infants and young children is really a taboo. Also, the static electricity adsorption of a large number of dust contains a variety of viruses, bacteria and harmful substances, they will make the baby's skin spots inflammation, resistance to weak babies may even trigger bronchitis, asthma and cardiac arrhythmia and so on!

Harm to the human body

The skin

Long-term in the open TV, computer and microwave ovens and other environments, it is often possible to have enlarged pores, skin dryness, erythema, itchy skin and other symptoms. The daily operation of the computer office white-collar face erythema, hyperpigmentation and other facial diseases of the probability of the incidence of far higher than those who do not use the computer, this is due to the computer screen generated by the electrostatic attraction of a large number of suspended dust, so that the face is stimulated by the cause. This is especially true for people with sensitive skin.

On the heart

In clinical practice, when some people are critically ill, may use a kind of electric shock to save the patient's life, because electric shock to the heart can defibrillate. It can be seen that a certain amount of electric current can play a role in saving lives, but normal people do not need electric current. If the static electricity carried by the human body in thousands of volts or even tens of thousands of volts, it will seriously interfere with or even change the potential difference inherent in the human body, especially affecting the normal work of the heart, may cause heart rate abnormalities and premature heartbeat. Winter 1/3 of the cardiovascular disease and static electricity, can not find the cause of heart disease, neurasthenia, nine out of ten people because of long-term interference by static electricity to.

The brain

Medical experts explain: dry static electricity on the brain does have an impact, it will cause the nerve cell membrane current conduction abnormalities, affecting the central nervous system, so that people feel fatigue, irritability, insomnia, headache.
