What is Static Electricity? What are the applications and prevention of static electricity?

Very small electricity will not cause any harm to people, and static electricity is unavoidable.

Static electricity refers to the reaction caused by the accumulation of positive and negative static electricity on an object, most of which is caused by friction or dry air.

It is a kind of electricity generated in a static state, which may be relatively dry, may be a lack of water, may be in contact with the power supply, and may be triboelectrified.

Static electricity is the charge at rest, and friction will produce this charge, including rubbing hair, and static electricity will also occur when clothes rub against clothes.

Static electricity is a kind of air produced by an item that carries electricity, and static electricity is generally generated after friction.

In life, static electricity is mostly contact static electricity, that is, when an uncharged object touches an object with static electricity, the charge moves from a high potential to a low potential, like water flowing to a low place, so the uncharged object generates electricity. Dry indoor is often a high-risk area of "electric charges", due to the low humidity of the air, chemical fiber clothing, carpets, cushions, wallpaper, etc. are rubbed, which will produce static electricity. If you touch live water pipes, electrical appliances, metal doorknobs, TV screens, and even switches with your hands, you will feel like being "electrified", and you will feel numb and painful.

If the static electricity accumulates to a certain voltage, the phenomenon of "electric shock" will occur when people come into contact with it. Although the voltage of static electricity is large, the resistance of the human body is also very large, and its current is small, and the energy it has is small, so it will not endanger human life.

However, static electricity with a voltage greater than 7,000 volts can change the inherent potential difference in the human body and affect the function of organs. People who are more sensitive to pain will feel uncomfortable when they are electrocuted, and the static electricity or sparks generated by some chemical fiber underwear sometimes cause the human body to itch and be unbearable; Objects with static electricity are very easy to absorb dust, and a large number of electrostatic charges on the phosphor screen of the TV have a great adsorption force on dust, and these dusts may also fall on the human body, resulting in rashes, acne and other diseases.

How to avoid static electricity from causing trouble in life?

The first is to reduce the generation of static electricity from the source.

Try to choose underwear, bed sheets, quilt covers, etc. made of natural textiles such as cotton, linen, silk, etc., and wear less clothing with chemical fiber texture;

Try not to put household appliances in the bedroom or put less to avoid the electric field generated by the human body and electrical appliances at close distance and contact with electricity;

It is best to stay more than 2 meters away from the TV when watching TV, and try to stay away from the computer and mobile phone when using it.

The second is to reduce the accumulation of static electricity, you can use the method of increasing indoor humidity, sprinkle some water on the ground, put a basin of water, and turn on the humidifier are good methods; Simply washing and drying your hands with clean water before using electrical equipment can also prevent static electricity from adsorbing on the human body.

The third is to release static electricity, use a key and other small metal devices or insulating rags to touch the items that may cause static electricity, and then touch it with your hand, so that it will not be electrified. ▲

In addition to the cold and dry weather in autumn and winter, there is also one of the most annoying points, which is the static electricity of the human body. Especially at night, if you turn off the lights and take off your sweater, you will see the crackling electric light of the sweater. When people touch something, they feel electrocuted, and these are all things that our human body is releasing static electricity.

How is static electricity generated?

There are two conditions that must be met for the human body to generate static electricity, the first is dry air, which is why it is easy to generate static electricity in the autumn season. The second is synthetic clothing.

The autumn season is dry, and there is no moisture on the surface, which leads to an increase in the resistance value, so that there is a large amount of charge accumulation in the local area. If you happen to be wearing non-conductive chemical fiber clothing at this time, the charge in the body cannot be conducted, when our fingers touch the conductive material such as metal, the static electricity in the human body will be suddenly released, and the fingers will naturally feel electrocuted.

What are the hazards of static electricity in the human body?

1. Cause **inflammation. Static electricity has a strong adsorption capacity and will adsorb many viruses, bacteria and harmful substances in dust. **Contamination with these things is naturally easy to trigger**inflammation.

2. Induce arrhythmia. Although the static electricity of the human body is not as strong as the real voltage, the voltage is still relatively large in an instant, and at this time people will feel a sense of dryness, irritability, and headache. During the autumn season, many people's cardiovascular diseases will become more serious, which is also related to human static electricity.

3. Leads to loss of blood calcium. If the air has been in a dry state and you continue to wear chemical fiber clothing, there will always be static electricity in the body, which will increase the alkalinity of the blood, reduce the content of calcium in the serum, and increase the excretion of calcium in the urine, which will lead to the loss of calcium in your own blood.

4. Affects the central nervous system. The human body is often affected by static electricity, which can cause abnormal electrical conduction of nerve cell membranes in the brain, making people feel dizzy, headache, irritability, insomnia, loss of appetite and other symptoms.

There are so many harms of static electricity, so how to avoid and reduce the harm of static electricity to the body in daily life?

1. Increase indoor air humidity. This one is also very simple, just use a humidifier at home. You should also pay attention to opening windows for ventilation.

2. Try to choose cotton or silk materials for clothes, and it is best not to choose chemical fibers.

3. Computers, TVs, air conditioners and other household appliances at home must be connected to the ground wire, which is safe and can reduce static electricity.

4. You can put a waste key in your pocket, and when you touch metal items again, take the key and touch the items first, so that the static electricity in the body can be conducted, and you don't have to worry about static electricity when you touch this kind of thing.

It is because the environment in which the body is located is too dry and full of electric particles, so static electricity will be generated, which is a physical phenomenon, and the impact is that there will be a lot of sparks, and in some cases it will catch fire.

Because the surrounding environment is relatively dry, coupled with some fibers on the clothes, static electricity is finally formed, which will lead to allergies, and will also cause people's mood to become particularly irritable.

It is because the friction produces some electric charges, and static electricity is generated after the relayout, which generally attracts each other, which may hurt **, and is likely to lead to cardiac arrest.

1. Clothing. Adding nanoparticles to textile and chemical fiber products can remove odor and sterilize. Although the chemical fiber cloth is strong, it has an annoying static electricity phenomenon, and a small amount of metal nanoparticles can be added to eliminate the static electricity phenomenon.

2. Food. Using nanomaterials, refrigerators can be antibacterial. Sterile tableware and aseptic food packaging supplies made of nanomaterials have been launched. The use of nano powder can make the wastewater completely clean and fully meet the drinking standard. Nano food is full of color, flavor and taste, and it is also good for health.

3. Live. The application of nanotechnology can improve the scrubbing resistance of wall coatings by 10 times. The surface of glass and ceramic tiles is coated with a nano-thin local layer, which can be made into self-cleaning glass and self-cleaning tiles, and there is no need to scrub at all.

Building materials containing nanoparticles can also absorb ultraviolet rays that are harmful to the human body.

4. OK. Nanomaterials can improve and improve the performance indicators of vehicles. Nano ceramics are expected to become ideal materials for engine parts such as automobiles, ships, and aircraft, and can greatly improve engine efficiency, working life and reliability.

Nanosatellites can provide traffic information to drivers at any time to help them drive safely.

1. Keys. Grip key touching metal: If you are afraid of static electricity when opening the door in winter, you can complete the discharge by pinching the key and touching the door, and the contact point of the discharge is not a point on the finger.

2. Metal objects.

Touching metal objects with your knuckles: Because there are fewer nerve endings in your knuckles, pain is less.

3. Humidifier.

Static buster. Other methods of removing static electricity:

1. Increase the contact area: If the electric charge has accumulated in our body, we can release the electric charge on the body as long as we simply "ground" the body, such as washing hands, touching water pipes, faucets or other grounded metal objects. However, when discharging, remember to contact the conductor in a large area, such as with the palm of your hand.

2. Keep holding on to the door frame when getting off: Make sure your hands are in contact with the metal door frame before getting off the bus, and you must keep in touch with it until you leave your seat completely.
