Why does friction produce static electricity, and why does friction produce static electricity

Dry weather should be anti-static.

The weather is dry, and many people begin to be "harassed" by static electricity frequently. Experts say that static electricity has a certain impact on health, and everyone should take measures to prevent static electricity.

Static electricity attaches to the surface of an object and releases energy only when it interacts with other objects. Long-lasting static electricity can cause an increase in the P value of the human blood, an increase in the excretion of calcium in the urine, and a decrease in blood calcium, so it is necessary to take appropriate precautions.

To prevent static electricity, you can place flowers and plants indoors or use a suitable humidifier to maintain proper humidity; Wear more cotton clothes and use skin care products with good moisturizing properties to ensure the best moisture.

It is understood that people in high-rise residential buildings are more likely to be "harassed" by static electricity, because the walls and floors are mostly insulators, and the indoor air is dry. People who have lived in high-rise buildings for a long time should often go outside to let the static electricity accumulated in the body be consumed through "output"; You can also walk barefoot in the house and let the footboard directly touch the ground to "discharge".

How to prevent being "bitten" by static electricity.

It is now a dry and cold winter. When using a car in winter, some car owners find that they will accidentally be electrocuted by static electricity when driving. Due to the many causes of static electricity, there are many ways to remove static electricity from the car

Three tips to "dodge" static electricity.

First of all, the simplest trick is: before opening the door, you can first touch the car door with the metal part of the key, and a simple action can not be easy to be electrocuted when driving; When getting out of the car, touch the metal part of the door with your hand before opening the door.

Secondly, try to retain the "moisture" in the car. Some car owners will ask, how to keep the moisture in the car if it can't be seen or touched? In fact, we only need to put a wet towel on the dashboard, or spray some water in the car with a sprayer regularly, which can increase the humidity in the car and reduce the effect of static electricity in the car; At the same time, when using the car at ordinary times, it is possible to retain the moisture in the car by turning on the internal circulation air conditioner less.

Thirdly, chemical fiber fabrics are the most susceptible to static electricity. For example, the cushions, floor cushions and other supplies in our cars can be dispensed with in autumn and winter, and leather or cotton products are used instead.

Make good use of tools to eliminate static electricity.

We can also use tools to remove static electricity, such as car wax and electrostatic dischargers. Some car waxes have certain anti-static functions, and in the dry season, car owners can choose electrostatic discharge products according to the different effects of car waxes. In addition, some vehicles have an antenna-like object (air arrester) at the rear of the vehicle, or a strip-shaped object fixed to the rear of the vehicle that hangs on the ground and contacts the surface (lap chain arrester), both of which are electrostatic dischargers specially designed for static electricity and can prevent most static electricity on the car.

This is a physical phenomenon, friction produces the transfer of positrons!

Friction produces static electricity, so how powerful is it?

Why friction produces static electricity is as follows:Friction is a major cause of static electricity, especially in dry environments.

The dry environment is one of the factors that cause static electricity. When the humidity in the air is lower than 30% in winter, it is easy to rub electricity; When the humidity reaches 45%, the probability of static electricity will be greatly reduced. To reduce static electricity, use an air humidifier indoors, or spray some water and plant to increase indoor humidity.

Electrostatic friction: the phenomenon of making two different objects charged by friction, or the phenomenon that two different objects rub against each other, one object is positively charged and the other object is negatively charged.

The frictiond object has the property of attracting small and light objects, which is the phenomenon of triboelectric induction. Its essence is the transfer of electric charge.

Electrostatic friction is the result of the transfer of electrons from one object to another, causing the two objects to carry an equal amount of charge. The object that gains electrons is negatively charged, and the object that loses electrons is positively charged. Therefore, when two uncharged objects are electrorically charged by friction, the amount of electricity they carry must be equal numerically.

Objects that have been rubbed have the phenomenon of attracting small and light objects.

Answer: "Static electricity" means that after an object gains or loses electrons, the number of positive charges in the nucleus of the object is greater or less than the number of electrons outside the nucleus, showing a "charged" state.

"Static electricity" is an electrical term that is different from "current". The electric current is formed by the directional movement of a free charge; And when static electricity is generated, there is generally no continuous current, and static electricity is due to the gain and loss of electrons.

The electrons outside the nucleus and nucleus of each atom carry an equal amount of electricity, and the electrical properties are opposite, and the whole atom is in an uncharged neutral state.

Different substances have different abilities for binding electrons to their nuclei. When friction, the nucleus of the atom with the strong ability to bind electrons takes some of the electrons from the atom with the weaker ability to bind the electrons. The negatively charged electrons are gained, and the positively charged electrons are lost.

Difference Between Electrostatic Phenomenon and Triboelectric Phenomenon:

1) Triboelectric initiation occurs between locations of different material compositions; Electrostatic induction can occur between different objects that are made up of the same material.

2) The two objects that are triboelectric must be in contact with each other, and the two objects do not touch each other when electrostatic induction.

3) After the triboelectric is electrified, the two objects carry the same amount of dissimilar charge; After electrostatic induction, the amount of charge carried by the induced object is indefinite.

4) The essence of triboelectric power is the transfer of electric charge between different substances; The essence of electrostatic induction is the redistribution of electric charges within the same object.

Matter is composed of atoms, the basic structure of atoms is protons, neutrons and electrons, under normal circumstances, the number of protons and electrons of an atom is the same, positive and negative balance, so it shows an uncharged phenomenon, but due to external effects, such as friction or in the form of various energies such as kinetic energy, potential energy, thermal energy, chemical energy, etc., the positive and negative electricity of atoms will be unbalanced, so the phenomenon of electrostatic electricity occurs.

Usually you can bring a battery, when there is static electricity on the clothes, you can use the positive pole of the battery to rub a few times on the clothes to discharge. The principle is that the positive pole of the battery is equal to the negative pole of the body, which is equal to the short circuit of the ground wire, and the discharge can remove the static electricity.

Any matter is made up 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 it exhibits an uncharged phenomenon externally. However, due to external actions such as friction or acting in the form of various energies such as kinetic energy, potential energy, thermal energy, chemical silver leakage energy, etc., the positive and negative electric imbalance of the atoms will be caused.
