What is the phenomenon of static electricity, how is the phenomenon of static electricity generated,

Relevant experts have done tests: rub a glass rod on the chemical fiber cloth 20 times, and immediately measure it with an instrument, and the results show that the maximum voltage can reach 150,000 volts. Taking off pure polyester clothes can instantly generate a high voltage of 50,000-100,000 volts.

Static electricity has a certain degree of harm to the human body, when the electrostatic voltage reaches 2000 volts, the fingers will feel it; When it exceeds 3000 volts, there are sparks, and the fingers have a pinprick-like pain; When it exceeds 7000 volts, the person has the sensation of electric shock.

When a person walking on the carpet rubs against the carpet and carries a large amount of electricity, when he reaches out to pull the metal doorknob, a spark discharge will occur between his hand and the metal handle (which has an induced charge on it), causing the person to feel electrocuted. If this kind of spark discharge occurs in factories and laboratories, it may also cause disasters. When the aircraft is flying, if the electricity carried by friction with the air is not guided away during the landing process, when the ground crew approaches the fuselage, a strong spark discharge may occur between the person and the aircraft, and in severe cases, the person may be knocked down.

Tank trucks specially used to load liquid fuels such as gasoline or diesel, in the process of filling and transporting, the oil and the oil tank rub and collide with a large amount of charge, if not led away in time, accumulate to a certain extent, will produce electric sparks, ignite the liquid fuel caused by **. On the surgical table in the hospital, there have also been electrostatic sparks to make ether**.

Anti-static product information network.

Static electricity is generated because of the transfer of electrons, and when the glass rod is rubbed against the silk, the electrons on it are transferred, thus exhibiting electrification. Static electricity is either caused by the loss of electrons or the accumulation of electrons.

The weather is dry. Wearing clothes made of chemical fibers is prone to static electricity.

As a result, many anti-static products have been derived.

For example, anti-static clothing, anti-static shoes, caps, ACLEAN nitrile gloves, etc

The methods of making an object electrostatic can be boiled down to three types, namely: triboelectric electrification, contact electrification, and inductive electrification.

a.Triboelectric Initiation: The phenomenon of frictional objects attracting small and light objects is the phenomenon of triboelectric activation.

Due to the different ability of the nucleus of different substances to bind electrons outside the nucleus, when two objects rub against each other, the nucleus of which object has a weak ability to bind electrons outside the nucleus, some of its electrons will be transferred to another object, the object that loses electrons is positively charged, and the object that gets electrons is negatively charged due to the excess electrons. Triboelectric is not essentially the creation of electricity, but the transfer of charge from one object to another, separating the positive and negative charges, and the total amount of charge does not change. Two objects rubbing against each other must have an equal amount of dissimilar charge, the positively charged object lacks electrons, and the negatively charged object has the same amount of excess electrons.

Only electrons outside the nucleus can be transferred during the transfer process, but the nucleus is stable. For example, a glass rod that has been rubbed against silk is positively charged.

b.Contact Charged: Contact charge is when a charged object comes into contact with an uncharged object (Note:

Here the uncharged object should be a conductor, and only with the conductor can the charge move freely on it), then the uncharged object also carries the same kind of charge as the charged object. When an object is charged and an object is uncharged, the total charge is redistributed and the charge moves in order to achieve equilibrium. Contact charge is the equilibrium of two objects being charged, and the end result is an electric charge of the same kind but not necessarily the same amount.

For example, if a negatively charged rubber rod is put into contact with an uncharged electroscope metal ball, the electroscope will be negatively charged and the metal foil will open.

c.Inductive charge: that is, electrostatic induction.

When a charged object approaches another uncharged conductor, the conductor will show a charge opposite to the charged body at the proximal end of the charged body, and a charge of the same properties as the charged body at the distal end of this metallic conductor. For example, when a positively charged object approaches an uncharged metal ball, the end near the charged body is negatively charged, and the end far from it is positively charged.

Induced charge is essentially the phenomenon of redistribution of charge in an object under the action of an electrostatic field. For example, the phenomenon of electrification on the display screen of a TV, computer, etc.

The ability of various substances to bind electrons is not the same, so the ability of substances to gain and lose electrons is also different, which causes various charged phenomena such as triboelectric electrolysis, that is, electrostatic phenomena. The phenomenon of static electricity is a physical phenomenon.

The phenomenon of static electricity is very common in life. When we comb our hair, sometimes we will find that the hair is getting more and more messy, and even produce "** head", when we come into contact with people, we will always be electrified, and when we touch a certain metal product, we will also feel that there is an electric current through the fingers, these are what we call static electricity.

Static electricity is caused by the transfer of electrons in the outer shell of atoms under the influence of various external forces, forming positive and negative ions respectively. Any two objects of different materials will be transferred and accumulated when they come into contact, forming static electricity.

Static electricity on a human body is mainly caused by friction between clothing objects or between clothing and body, so the amount of "electricity" when wearing clothing of different materials is different.

For example, clothing made of chemical fibers is more likely to produce static electricity, while cotton clothing produces less. And because the dry environment is more conducive to the transfer and accumulation of electric charge, people will feel that the static electricity on their bodies is greater in winter.

Under different humidity conditions, the electrostatic potential generated by human activity is different. In the dry season, the static electricity of the human body can reach thousands of volts or even tens of thousands of volts. Experiments have proved that there is no discomfort in the human body when the electrostatic voltage is 50,000 volts, and there is no danger to life when the electrostatic voltage is 120,000 volts.

However, electrostatic discharges also create electromagnetic fields around them, which are of great intensity, although they last for a short period of time. Researchers are studying the effects of electrostatic electromagnetic fields on the human body.

Static electricity is a kind of electric charge that is at rest or does not flow (a flowing charge forms an electric current).

Static electricity is formed when the charge is gathered on an object or surface, and the charge is divided into two types: positive charge and negative charge, that is to say, the phenomenon of static electricity is also divided into two types, namely positive static electricity and negative static electricity.

Positive static electricity is formed when positive charges are gathered on an object, and negative static electricity is formed when negative charges are gathered on an object, but it is either positive or negative static electricity.

Charge transfer occurs when an electrostatic object comes into contact with a zero-potential object (grounded object) or an object with a potential difference, which is the phenomenon of spark discharge that we see every day.

Electrostatic phenomenon: The ability of the atomic nucleus of various substances to bind electrons is different, so the ability of substances to gain and lose electrons is also different, which causes various charged phenomena such as triboelectric conduction.

Metals are prone to loss of electrons in their outer shells, and these electrons that run out of atoms are called "free electrons", so metals tend to conduct electricity.

The electrons in the insulator are bound by the nucleus and are not easily free electrons, so it does not conduct electricity easily. However, by using high-intensity electric power and high temperature, some electrons can be freed from the bondage of the nucleus and become free electrons, so the insulator becomes a conductor.
