Question 2: What are the circumstances that make it easy to generate static electricity? Winter is coming, often by the static electricity to make a mess, quite difficult.
When the human body activities, skin and clothing and clothing and clothing friction between each other, will produce static electricity. With the increase in household appliances and winter people wear more chemical fiber clothing, household appliances generated by the electrostatic charge will be absorbed by the body and accumulated, coupled with indoor walls and floors are mostly insulators, air dry, so it is more likely to be interfered with by static electricity.
As the skin of the elderly is relatively drier than that of young people, as well as the aging of the cardiovascular system of the elderly, the ability to resist interference is weakened and other factors, so the elderly are more susceptible to the effects of static electricity. The cardiovascular system has been a variety of lesions in the elderly, static electricity will make the condition worse or induce premature ventricular contractions and other arrhythmias. Excessive static electricity also often makes people restless, headache, chest tightness, breathing difficulties, coughing.
In order to prevent the occurrence of static electricity, indoor to maintain a certain degree of humidity, indoor to diligently mopping, diligently sprinkle some water, or humidification with a humidifier; to be diligent in bathing, diligent change of clothes, in order to eliminate the static charge accumulated on the surface of the human body. When you find that your hair can not be combed, dip the comb into the water for a few moments, and when the static electricity is eliminated, you can comb your hair into service. After undressing, gently touch the wall with your hand, touch the door handle or faucet before you also need to touch the wall with your hand, the body of static electricity "discharge" out, so that static electricity will not hurt you. For the elderly, should choose soft, smooth cotton or silk woven underwear, ***, as far as possible *** chemical fiber clothing, in order to minimize the harm of static electricity.
1, go out and wash your hands before, or first put your hand on the wall to wipe a go to remove static electricity! And try to *** flower fiber 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, faucets, 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, hold the gear with your right hand, 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 with the iron position, but don't let go of your left hand, and then let go of your right hand, get off the car, and then you will not be electrocuted by the right hand holding the door ~~ ha. 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 accessories fabrics, try to avoid the use of chemical fiber carpets and plastic as the surface material of the furniture 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: in the heating placed under 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 to 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.
6, diligent bathing, change clothes, can effectively eliminate the static electricity accumulated on the surface of the human body.
People in their daily lives, sometimes due to wear, climate, friction and other reasons, often leading to the accumulation of static electricity in the body, and suddenly touched the metal, will be invoked by the pain of electric shock, a certain stage of the frequent occurrence of even can cause some kind of psychological pressure. If you avoid touching iron for a while, the charge on your body may accumulate more, and sooner or later, you will suffer a greater electric shock.
Here are two tips to help prevent such shocks.
Instead of touching a metal door directly with your hand, grab a bunch of keys in your pocket with your hand (usually this doesn't get you a shock), and then touch the door with the tip of one of the keys so that the charge is discharged and you don't get a shock.
Principle: The pain of the discharge on the hand is due to the high voltage discharge, as the sudden contact between the hand and the door is a very small area of contact, thus generating an instantaneous high voltage. If you take out the keys in your pocket, first hold the keys over a large area (a set of keys itself can not transfer much charge and thus there will be no electric shock at this time), and then use the tip of a key to contact a large conductor, at this time, the point of contact of the discharge is not a point on the skin of the hand, but rather the tip of the key, and thus the hand will not feel the pain (maybe the key will.)! ---- if it feels pain).
2. Electrocution also often occurs when getting out of a cab. Mainly due to the friction between the body and the seat when getting out of the car to produce static electricity accumulation, and when you get out of the car and close the door, the hand suddenly ...... >>
Question 3: How to generate a relatively strong static electricity? We all know that computer equipment is most afraid of static electricity, looks insignificant static electricity can cause permanent damage to computer chips. Since the computer is so afraid of static electricity, then why computer equipment will produce static electricity? In junior high school, we know that friction can generate electricity, with a glass rod in the fur on the rubbing can generate static electricity, its voltage up to thousands of volts, or even tens of thousands of volts. Similarly, we are wearing chemical fiber products of clothing, laid on the floor of the chemical fiber carpet in our movement will produce static electricity, so when we come into contact with the earth connected to the metal objects, sometimes there will be a feeling of electric shock. Don't underestimate such a slight electric shock, if it is on the computer chip discharge, it will make your computer rest forever. How does static electricity actually occur? In addition to the above chemical fiber clothing and carpets, monitors, switching power supplies, soldering irons, cell phones, etc. will produce static electricity. 1, CRT display because of its internal high pressure of about 30,000 volts, in its work, high pressure will be because of the principle of the Ferrari container in the surface of the display to produce a certain amount of charge, if the surrounding environment is relatively dry, the charge can not be discharged, the accumulation of a long time will form a higher voltage positive charge. So sometimes we touch the surface of the CRT will have the feeling of electric shock. 2, switching power supply and some accessories in the work will radiate a large number of high-frequency electromagnetic waves to the surrounding area, if there are metal objects around, these electromagnetic waves carrying energy will be absorbed by metal objects such as chassis, part of which can be converted into heat (which is the principle of microwave ovens), part of which will be converted into electric charge in the accumulation of the metal surface (or not there is news that the future can be sent to the moon through the electric (or there is news that in the future it will be possible to transmit the electricity generated on the moon to the earth via microwaves). If the metal object is ungrounded or poorly grounded, this charge will increase over time. If there are suitable conditions will be discharged externally. 3, the surface of the soldering iron will also be charged, the general maintenance personnel know this. Or you can use a test pen to test the soldering iron is heating, the light of the pen will be bright. This part of the charge is mainly when the soldering iron inside the insulation layer of the resistance wire work in the high temperature state will show a high resistance state, then there will be a small amount of charge free to the surface of the soldering iron, so that the soldering iron charged. For this situation, we can put the soldering iron power plug reverse 180 degrees and then inserted into the power supply to use, the surface of the charge will be reduced a lot. But when the use of 220V soldering iron welding CMOS components, for safety reasons, be sure to ensure that the soldering iron is well grounded, or the soldering iron is powered off after welding. 4, cell phone, wireless walkie-talkie in the work, will be launched into the space of a large number of radio waves. Because cell phones, walkie-talkies work at a high frequency, the energy it emits will be greater and more. If you are interested, you can try, 3W walkie-talkie can light up 12W energy-saving lamps, 40W fluorescent lamps are also able to light up. Again static electricity is generated around it. So when we use cell phones to make phone calls, the time is better not too long. Since we know the harm of static electricity is so powerful, then how can we effectively prevent static electricity to cause damage? 1, for the safety of computer equipment, for the school or other conditions of the unit, the collective use of computers, in the computer classroom must be paved with anti-static flooring, never use ordinary chemical fiber carpets. 2, computer equipment using the power supply, the ground line must be well grounded. It is recommended to use a three-hole power outlet, of course, the power cord must also be three-pin. Some friends use a wire to connect the chassis appearance and the earth or water pipe, this method does not achieve good results. 3, if there is no grounding equipment, when we want to use our hands to contact the board, we must use our hands to touch the tap water pipe or damp ground, to discharge the static electricity carried by their own bodies, to avoid personal discharge on the board when contacting the board, resulting in damage to the board. Especially in winter, dry and cold, we wear mostly wool and chemical fiber products, the most likely to produce static electricity.
Question 4: Often easy to generate static electricity, how ah? It is the reason that the climate is dry, and there is no connection with the physique, you just make it according to the following method, it is very useful!
How to prevent static electricity?
Is there anything we can do about the ubiquitous static electricity? Don't worry, there is always a way to deal with it.
Maintain a certain degree of humidity in the room to raise some potted plants or ornamental fish, you can also use a humidifier to increase the humidity of the room. If these conditions are not available, then you can also sprinkle a little water in the room, put a basin or two of water or diligently mop the floor. Recommended to you an economical and practical method of humidification: put a basin of water under the heater, use an old towel (or absorbent cloth), one end in the water, one end on the heater, so that around the clock can be evaporated into the house about 3 liters of water. If every heater does this, the whole room will feel moist and pleasant.
Make your own ground wire You can use a piece of metal wire to make a ground wire for other electrical appliances, such as a TV, to help the appliance evacuate the static electricity it generates through this ground wire.
Use cotton or pure wool instead of chemical fiber for the elderly, children, electrostatic sensitivity, can not find the cause of heart disease, neurasthenia and psychiatric patients, etc. It is recommended to wear cotton underwear in the winter, ***, was lined, sheets, covers, etc., to be used in the natural textile, as far as possible, do not wear chemical fiber texture of the garment, in order to reduce the adverse effects of static electricity on the person. Chemical fiber carpet is also the culprit in the manufacture of static electricity, so when choosing these items it is best to choose pure cotton fabrics or pure woolen fabrics, which will reduce some of the static electricity. Mutual
Diligent hand washing, face washing Television should not be placed in the bedroom. People watching TV should open the window, with the TV set to maintain a distance of 2-3 meters. Because static dust will gather on the skin, so after watching TV or using the computer, be sure to wash your hands and face.
Avoid static electricity hit, there are some tips, such as usually also available small metal devices (such as keys), cotton rags, etc. first touch the door, door handle, faucet, chair back, bed rails, etc. to eliminate static electricity, and then touch with your hands.
Diligent bathing, changing clothes, can effectively eliminate the accumulation of static electricity on the surface of the human body.
When the hair can not be combed to serve, the comb will be immersed in water, and so on after the elimination of static electricity, you can feel free to comb. Try to use a moisturizer or conditioner when washing your hair.
Barefoot is conducive to the release of static electricity accumulated on the surface of the body. So don't miss any opportunity to go barefoot when you're relaxing.
Eat more vegetables, fruits, yogurt and other acidic foods, drink more water, while supplementing calcium and vitamin C to reduce the effects of static electricity.
By the way, static electricity is also very harmful to petrochemical companies, especially gas stations, gas guns are easy to accumulate static charge, refueling is very easy to produce sparks, so before refueling, it is best to release the static charge on the gas gun to the release, such as touching the gas gun to the periphery of the metal objects and so on.
Issue 5: the four main sources of static electricity electronic industrial production sources of static electricity can be broadly divided into two categories:
1, the chip, the static electricity on the PCB board: in the patch drying, surface drying, hot air blowing, and conveyor belt friction and so on, some static electricity will accumulate, and the chip's antistatic ability is very weak, a few hundred volts of static electricity may result in breakdowns, damage to the chip.
2, the human body on the static electricity: a human activity friction with static electricity, and then touch the chip to do the check is easy to cause a discharge breakdown, so the electronics industry to do human protection.
Question six: How does static electricity arise and how to eliminate it? Matter is composed of molecules, molecules are composed of atoms, atoms have negatively charged electrons and positively charged protons. Under normal conditions, an atom of the number of protons and electrons, the same number of positive and negative balance, so the external performance of the phenomenon of uncharged. However, the electrons around the nucleus of the atom, once the external force that is out of orbit, leaving the original atom and invade other atoms B, A atoms due to the lack of electrons with a positively charged phenomenon known as cations, B atoms due to the increase in the number of electrons and negatively charged phenomenon, known as anions. The reason for the unbalanced electron distribution is that the electrons from the orbit by external forces, this external force contains a variety of energy (such as kinetic energy, potential energy, thermal energy, chemical energy ......, etc.) in daily life, any two different materials in contact with the object and then separated, you can produce static electricity. When two different objects in contact with each other will make an object to lose some of the charge such as electrons transferred to another object so that it is positively charged, and another body to get some of the remaining electrons of the object and negatively charged. If it is difficult to neutralize the charge in the process of separation, the charge will accumulate to make the object with static electricity. So the object and other objects in contact with the separation will be charged with static electricity. Usually in an object from a plastic film is a typical peeling a typical "contact separation" of electricity, in daily life to take off the clothes generated by the static electricity is also "contact separation" of electricity. Solids, liquids and even gases can be charged by contact separation. This is because the gas is also composed of molecules, atoms, when the air flow molecules, atoms will also occur "contact separation" and the electricity. We all know that friction generates electricity, but we seldom hear that contact generates electricity. In essence, friction is a process of contact and separation, resulting in an imbalance of positive and negative charges. Friction is a continuous process of contact and separation. Therefore, friction is essentially contact and separation. In daily life, all kinds of objects can be moved or friction and generate static electricity. Another common type of electrification is inductive electrification. When a charged object approaches an uncharged object, it induces negative and positive charges at the ends of the uncharged conductor. In the dry and windy autumn, in our daily lives, we often come across this phenomenon: undressing at night to sleep, the darkness often hear the crackling sound, and accompanied by blue light, meet to shake hands, the fingers just touch each other, will suddenly feel the fingertips of the needle-like pain, alarming; get up in the morning to comb your hair, hair will often "floating" up, the more you care more and more. "up, more and more messy, pull the door handle, open the faucet will be "electrocuted", often issued a "pop, pop" sound, which is occurring in the human body of static electricity, the above phenomena is the body of static electricity to external The above phenomena is the body of electrostatic external "discharge" results. How to prevent static electricity [Edit paragraph] human activity, skin and clothing and clothing and clothing friction between each other, will produce static electricity. With the increase in household appliances and winter people wear more chemical fiber clothes, household appliances generated by the static charge will be absorbed by the human body and accumulated, coupled with indoor walls and floors are mostly insulators, the air is dry, and therefore more susceptible to static interference. Due to the elderly skin is relatively drier than young people, as well as the aging of the cardiovascular system of the elderly, anti-interference ability to weaken and other factors, so the elderly are more susceptible to the effects of static electricity. The cardiovascular system already has a variety of lesions in the elderly, static electricity will make the condition worse or induce premature ventricular contractions and other cardiac arrhythmias. Excessive static electricity also often makes people restless, headache, chest tightness, breathing difficulties, cough. In order to prevent the occurrence of static electricity, indoor to maintain a certain degree of humidity, indoor to mop the floor, sprinkle some water, or humidifier humidification; to bathe regularly, change clothes, in order to eliminate the static charge accumulated on the surface of the human body. When you find that your hair can not be combed, dip the comb into the water for a few moments, and when the static electricity is eliminated, you can comb your hair into service. After undressing, gently touch the wall with your hand, touch the door knob or faucet before you also need to touch the wall with your hand, the body of static electricity "discharge" out, so that static electricity will not hurt you. For the elderly, should choose soft, smooth cotton or silk underwear, ***, as far as possible *** chemical fiber clothing, in order to minimize the harm of static electricity. 1, go out and wash your hands, or first put your hand on the wall to wipe a go in addition to static electricity, and try to *** chemical fiber 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, faucets, chair backs, bed rails and other elimination of static electricity, and then touch the hand. 3, wear cotton underwear. 4, ready to get off the car, hold the gear with your right hand, 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 with iron, but don't let go of your left hand, and then put ...... >>
Question 7: What are the three main causes of static electricity Any substance is made up of a combination of atoms, and the basic structure of atoms is protons, neutrons and electrons. Scientists define protons as positively charged, neutrons are uncharged, and electrons are negatively charged. Under normal conditions, the number of protons and electrons of an atom is the same, and the positive and negative charges are balanced, so the external phenomenon is not charged. However, due to external effects such as friction or a variety of energy such as kinetic energy, potential energy, thermal energy, chemical energy, etc., the form of action will make the atom's positive and negative electric imbalance. Friction in everyday life is essentially a process of constant contact and separation. In some cases, no friction can also produce static electricity, such as induced electrostatic discharge, thermoelectric and piezoelectric discharge, Helmholtz layer, jet discharge and so on. Any two different materials in contact with the object and then separated, can produce static electricity, and the universal method of generating static electricity, is friction generated electricity. The better the insulation of the material, the easier it is to generate static electricity. Since air is also made up of a combination of atoms, it can be said that static electricity can be generated at any time and any place where people live. To completely eliminate static electricity is almost impossible, but can take some measures to control static electricity so that it does not produce harm.
Through the friction caused by the redistribution of charge and the formation of, but also due to the mutual attraction of charge caused by the redistribution of the formation of charge, specifically because of the material are composed of atoms, atoms have a negatively charged electrons and positively charged nuclei. Generally speaking, the positive charge of the nucleus and the negative charge of the electron is equal to the positive and negative balance, so it does not show electrical. However, if the electrons by external forces and out of orbit, resulting in an unbalanced distribution of electrons, such as friction is essentially a process that causes an imbalance between positive and negative charges. When two different objects are in contact with each other and rubbing each other, an object of electrons transferred to another object, because of the lack of electrons and positively charged, while the other object to get some of the remaining electrons of the object and negatively charged, the object with the static electricity.
Question 8: How does static electricity (to be particularly simple and clear) (20 words) Different substances have different ability to lose electrons, the electronic transfer occurs in contact, and then separated after contact, you can generate static electricity
Question 9: How to solve the problem of static electricity How to prevent electrostatic electricity in daily life?
1, the bedroom as far as possible not to put or less put household appliances. This can avoid the human body and electrical appliances in close proximity to produce an electric field and touch the static electricity, watching TV is best to distance from the TV set 2 to 3 meters.
2, with the "third party" to eliminate static electricity. In order to avoid static electricity hit, available small metal devices (such as keys), cotton rags, etc. can cause static electricity first touch the door, doorknobs, faucets, chair backs, bed rails, etc. to eliminate the static electricity, and then touch the hand.
3, with natural fabrics. Underwear, bed sheets, covers, etc. Try to use cotton, hemp, silk and other natural textiles, try not to use or wear chemical fiber texture home textiles and clothing.
4, with wooden comb, moisturizer. Comb your hair with a wooden comb, shampoo with hair lotion, can eliminate static electricity.
5, keep the room temperature. So that static electricity is not easy to produce. In winter, it is best to use a humidifier indoors, you can also place flowers and plants to avoid static electricity.
6, flooring, walls, ceilings, etc. Use anti-room static material.
7, eat more vegetables, fruits, yogurt, drink more water, while supplementing calcium and vitamin C to reduce the impact of static electricity. 8, there is also can be in the handle on the wall, can export static electricity
How to prevent static electricity with a car?
Installation of electrostatic discharge. Electrostatic discharger is divided into grounded and air discharge type, but according to experts, the trend is to install two sets of them, so that the effect of eliminating static electricity than a single set of ideal.
Spray anti-static spray. There is a new listing called "anti-static spray" product, spray it evenly on the car and then wipe off with a towel, the car has a magical anti-static effect, and the validity period is not short!
Less cosmetics. For female car owners, in the dry environment should pay attention to minimize the use of cosmetics, heavy makeup will make the skin more dry.
Less open air conditioning. Especially the internal circulation air conditioning, so that the car itself is already very dry can not store a little moisture. It is recommended to keep the windows half open (to avoid letting the wind blow directly on the body), even if the body is a little sweaty, it does not matter, appropriate to promote the secretion of sweat glands on the skin instead of better.
Spread a wet towel. With a wet towel spread on the dashboard, the use of sunlight to make the water inside the towel quickly evaporate, thus increasing the humidity inside the car
Problem 10: How to reduce static electricity Into the winter, the weather is dry, and many people are frequently subjected to static electricity "harassment". Grip, pull the door handle, press the elevator button or even open the faucet will be "electrocuted", often occurring "snap, snap" sound, the hand has a feeling of electric shock, which is the human body accumulates static electricity to a certain number of discharge. Nowadays, many people live in high-rise buildings, the human body will absorb and accumulate a variety of household appliances generated by the electrostatic charge, coupled with indoor walls and floors belonging to the nail edge of the body, so these people are more susceptible to electrostatic interference. Experts warned that do not think that static electricity is just difficult to a moment, it is in fact a negative impact on human health, so it is necessary to take appropriate precautions.
There have been medical experts have confirmed that the skin electrostatic interference can change the normal potential difference between the human body surface, affecting the normal electrophysiological process of myocardial and cardiac normal conduction. This static electricity can make the patient aggravated or induced premature beats, serious neurasthenia, mental illness and heart disease patients constitute a potential threat. Persistent static electricity will also make the blood alkaline, serum calcium content decreased, calcium excretion increased, leading to skin itching, hyperpigmentation, affecting the physiological balance of the human organism, interfere with human emotions. In addition, the daily operation of the computer office white-collar workers or long-term stay in the home appliances more environment, the face often triggered erythema, hyperpigmentation and other facial diseases, which are due to the computer screen or home appliances electric field generated by the static electricity, so that the air microorganisms, dust on the static, adsorbed in the skin, and over time *** the skin and the production of.
The medical experts pointed out that for the body to accumulate more static electricity, you can "output" way to consume it. Static electricity more people should try to wear less chemical fiber clothing, chemical fiber clothing for anti-static treatment, personal clothing, bedding to choose cotton products or silk products, home as much as possible do not use chemical fiber carpet. Indoor to maintain a certain degree of humidity, such as commonly used wet mop mopping, sprinkle some water, or use a humidifier humidification, to prevent static electricity is good; you can also use the negative ion generator, some of the positive charge to neutralize, or in the room put a pot of cold water or plant some potted plants and flowers. Prolonged use of computers or watch TV, to wash with soap in a timely manner *** of the skin, in order to "drive" away the static electricity on the skin. In addition, but also to avoid staying a long time in the electrostatic occasions, such as computers focused on the production room, reduce the harm of static electricity on people.
