    This is because the pen will carry an electric charge when rubbed, and the charged pen will have an attraction effect on small, uncharged objects. Therefore, the rubbed pen can pick up scraps of paper.

    Causes of triboelectric power.

    The reason for triboelectric electricity is that when two objects rub against each other, because the nuclei of different objects have different abilities to bind electrons outside the nucleus, one of them must lose some electrons and the other object gains excess electrons. Thus generating an electric charge.

    For example, if a glass rod is rubbed against the hair, some of the electrons of the glass rod are transferred to the hair, and the glass rod is positively charged due to the loss of electrons, and the hair is negatively charged by the electrons. Rub the rubber rod against the fur, some of the electrons of the fur are transferred to the rubber rod, the fur belt is positively charged, and the rubber rod carries the same amount of negative electricity.

    The reason why hair can absorb paper after rubbing is that friction is electrified.

    The phenomenon of using friction to electrify two different objects is called triboelectric electricity, or the phenomenon that after two different objects rub against each other, one object is positively charged and the other object is negatively charged.

    Triboelectric is the result of the transfer of electrons from one object to another, and both objects carry an equal amount of charge. The object that gains electrons is negatively charged, and the object that loses electrons is positively charged. It turns out that when two uncharged objects are electrolyzed by friction, the amount of electricity they carry must be equal numerically.

    There are only two kinds of electric charges in nature, and the charge of the glass rod that has been rubbed by silk is called a positive charge.

    The charge of a rubber rod that has been rubbed with fur is called a negative charge. The same charge repells each other, and the different charges attract each other. Any two objects rubbing against each other can be electrified. The essence of triboelectric power is the transfer of electric charge.

    The principle of triboelectric induction can be widely applied to life, and the electrical energy generated by the movement of electrons caused by friction can make the lamp shine, and this energy can be collected and reused.

    Despise plastic products. When rubbed against the hair, static electricity is generated on the pen. Tin foil is available when entering the store. You can rub it on other fur with a pen, which can also generate static electricity. And not just hair.

    The name of rubbing the sticker paper on the hair with a pen is called friction to produce an electrostatic reaction. Rub the plastic pen barrel on the hair, and then use the pen barrel to get close to the small paper scraps, and find that the small paper scraps will fly to the plastic pen barrel, the reason is that the charged body can attract light objects, and some of the small paper scraps will bounce off after touching the pen barrel, and the reason is that the same charge repels each other.

    A common way to eliminate static electricity

    Grounding is the simplest and most basic way to eliminate electrostatic hazards. It is mainly used to eliminate static electricity on the conductor, and should not be used to eliminate the static electricity on the insulator. In order to eliminate the static electricity on the conductor, the ground resistance is 1000 times.

    The electrostatic grounding must be secure and mechanically strong.

    Humidification is the process of increasing the humidity of the air to eliminate the accumulation of electrostatic charges. In places with static electricity hazards, if the process conditions permit, air conditioning equipment, sprayers can be installed or hanging wet cloth strips and other square coding methods can be used to increase the relative humidity of the air. From the perspective of eliminating electrostatic hazards, it is more appropriate to keep the relative humidity above 70%.

    For places with a risk of static electricity, the relative humidity should not be less than 30%.

    Add antistatic additives, and electrostatic additives are special auxiliaries. Generally, only a few thousandths or a few thousandths of a trace amount need to be added to eliminate static electricity in the production process. Sulfonates, quaternary amine salts and other electrostatic additives that can be used in plastics and chemical fibers.

    Oleate and naphthenate can be used as electrostatic additives for petroleum industry. Acetylene, carbon ink, etc. can be used as electrostatic additives for rubber unemployed. When using electrostatic additives, it should not affect the performance of the product.

    In addition, care should be taken to prevent the toxicity and corrosiveness of certain additives.

    Electrostatic neutralizer. Static neutralizers, also known as static eliminators, are done with the help of electricity and ions. According to the different working principles and structures, they can be roughly divided into induction neutralizers, high-pressure neutralizers, radiation neutralizers and ion current neutralizers.

    During friction, electrons are transferred from one object to another, a phenomenon known as the electrostatic effect. When you rub your hair with plastic, the friction causes the hair to lose some of the kihukai electrons, which the plastic gets. Since hair and plastic are made of different materials, they also have different tolerances for electrons, so hair becomes positively charged, while plastic is negatively charged.

    This charged hair acts like a small magnet that attracts surrounding matter, especially those with opposite charges. Pieces of paper are usually slightly negatively charged, so they become trapped when they are brought close to positively charged hair. This phenomenon is known as electrostatic adhesion.

    In the same way, when plastics rub wool, wool and other materials, they will also produce similar electrostatic effects, resulting in the corresponding charge of these materials, resulting in electrostatic adsorption.

    It is important to note that the electrostatic effect, while interesting, can also lead to some safety issues, such as the accumulation of static electricity in dry weather, which can lead to situations such as electric shock or fire, so it is important to pay attention to safe use.

    This is because the pen that has been rubbed through the hair generates static electricity during the friction process. Static electricity attracts shredded paper.
