Hazards of static electricity:
Harm of static electricity in industry: the generation of static electricity in industrial production is inevitable, and its harm can be mainly attributed to the following two mechanisms: First, the harm caused by electrostatic discharge (ESD): failure or misoperation of electronic equipment and electromagnetic interference.
Break through integrated circuits and precision electronic components, or promote component aging and reduce production yield. ?
High voltage electrostatic discharge leads to electric shock, which endangers personal safety. ?
It is easy to cause explosion and fire in the production place where there are many inflammable and explosive articles or dust and oil mist. ?
Secondly, the harm caused by electrostatic attraction (ESA): electronic industry: dust adsorption causes pollution of integrated circuits and semiconductor components, which greatly reduces the yield.
Film and plastic industry: make film or film roll uneven; Film and CD plastic discs are polluted by dust, which affects the quality. ?
Paper-making and printing industry: uneven winding of paper, inaccurate overprinting, serious dirt absorption, and even paper sticking, which affects production. ?
Textile industry: causes root silk fluttering, broken flowers, yarn entanglement and other hazards. ?
Harm to skin: Long-term exposure to open TV, computer and microwave oven will often lead to symptoms such as large pores, dry skin, erythema and itchy skin. However, the incidence of facial diseases such as erythema and pigmentation in office white-collar workers who operate computers every day is much higher than that in people who do not use computers. This is because the static electricity generated by the computer screen will attract a lot of suspended dust, causing facial irritation. This is especially true for people with sensitive skin. ?
Harm to the heart: clinically, when some people are critically ill, electric shock may be used to save the patient's life, because electric shock can defibrillation. It can be seen that a certain current can save people, but normal people don't need current. If the static electricity carried by the human body is several thousand volts or even tens of thousands of volts, it will seriously interfere with or even change the inherent potential difference of the human body, especially affect the normal work of the heart, which may cause abnormal heart rate and premature beats. Winter13 cardiovascular diseases are related to static electricity, and nine times out of ten patients with heart disease and neurasthenia who can't find the cause are caused by static electricity for a long time. ?
Harm to the brain: Medical experts explain that the static electricity generated by dryness does have an impact on the brain, which will cause abnormal current conduction of nerve cell membrane, affect people's central nervous system, and make people feel tired, fidgety, insomnia and headache. First of all, we should make it clear that static phenomena can be divided into positive static and negative static. For example, static electricity generated by computer screens will attract a lot of suspended dust, and static electricity is not allowed in gas stations. To this end, a static elimination device will be installed near the fuel tank. The "static electricity" in these aspects refers to positive static electricity, which is also easy to cause harm to human body. However, we can't generally think that all electrostatic phenomena are harmful to human body. Positive electrostatic radiation is harmful to human body, while negative electrostatic radiation is harmless to human body. Among them, the electrostatic therapeutic apparatus approved by the US Food and Drug Administration and widely sold and used in the market and clinic uses negative static electricity to treat diseases.
On the other hand, healthy human cells are all negatively charged, and the charges of healthy red blood cells, white blood cells and colloidal particles in blood are also negatively charged. In this way, cells repel each other negatively, so that cells in human blood always flow normally in a state of suspension and separation. Therefore, negative static electricity is not only harmless to human body, but also of great significance to normal physiological activities of human body. In many medical books, there are also detailed introductions about electrostatic therapy. In real life, if the air negative ion generator such as Senpeptide is used to optimize the environment, when human skin is dry or chemical fiber clothes move near the air negative ion generator, some negative ions (negative charges) will temporarily gather on the surface of human body or clothes due to the high concentration of negative ions. At this time, when touching others, walls or conductors, electrostatic discharge similar to acupuncture will occur. This is caused by the transfer of negative ions (negative charges) accumulated on clothes. This static phenomenon is normal and harmless to human body, so users need not worry. This static phenomenon can be easily eliminated by placing plants indoors or humidifying the air with a humidifier. In addition, it is suggested to use negative air ions for recuperation and health care, and try to wear cotton clothes when inhaling at close range or wash your face with water after use, which can effectively avoid static electricity.
