Anonymous users2024-02-06The principle of static electricity:Static electricity is formed by the redistribution of charges caused by friction, and there are also forms of redistribution of charges due to the mutual attraction of charges. In general, the positive charge of the nucleus is equal to the negative charge of the electron, and the positive and negative are balanced, so it is not electrically visible.
However, if the electrons are deorbited by an external force, resulting in an unbalanced electron distribution, for example, triboelectric is essentially a process that causes an imbalance of positive and negative charges. When two different objects touch each other and rub against each other, the electrons of one object are transferred to the other and become positively charged because of the lack of electrons, while the other body gets some remaining electrons and the object is negatively charged, and the object is electrostatic.
Electrostatic phenomenon. Static electricity phenomena include many natural examples, such as the attraction between a plastic bag and a hand, a seemingly spontaneous barn**, the destruction of electronic components during the manufacturing process, the workings of photocopiers, and so on. When the surface of an object comes into contact with other surfaces, the charge collects on the surface of the object and becomes static electricity.
Although charge exchange occurs due to the contact and separation of two surfaces, the effect of charge exchange is only noticed when the resistance of one of the surfaces is high and the current becomes very small. Because, the charge will sink into that surface and spend a long time there, long enough for the effect to be observed.

2. Principle of electrostatics: Under normal conditions, the number of protons and the number of electrons of an atom are the same, positive and negative balance, and the phenomenon of uncharged is exhibited externally. However, the electrons surround the nucleus, and as soon as they are separated from their orbits by external force, they leave the original atom and invade other atoms B, a atom is positively charged due to the lack of electron number, which is called cation, and B atom is negatively charged due to the increase in the number of electrons, which is called anion.
Any two objects of different materials that come into contact and then separate can generate static electricity.

Anonymous users2024-02-04Electrostatic has applications such as electrostatic copying, electrostatic precipitation, electrostatic discharge, and electrostatic spraying.
Electrostatic copying: Electrostatic photocopying is a method of obtaining a copy using the principle of electrostatic induction. When the surface of the photosensitive material with static electricity is made by electrostatic induction, the local charge changes with the intensity of the light according to the image and the electrostatic latent image is retained, and the copy is obtained by a certain dry development, image transfer and fixing.
It has the advantages of being simple, fast, clear, expandable and miniaturized, and can also copy color originals.
Electrostatic precipitator: Electrostatic precipitator is the use of electrostatic field to make the suspended dust particles in the gas charged and adsorbed, and separate the dust particles from the flue gas to remove them.
Electrostatic discharge: Electrostatic discharge, or ESD, refers to the transfer of electric charge caused by objects with different electrostatic potentials coming close to each other or in direct contact.
Electrostatic spraying: Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make the negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece. A thicker coating can be obtained in a single coating.
Very small electricity will not cause any harm to people, and static electricity is unavoidable.
Compared with other dust removal equipment, the <> electrostatic precipitator has less energy consumption and high dust removal efficiency, which is suitable for removing 0 01-50 m dust in the flue gas, and can be used in the occasion of high flue gas temperature and high pressure. Practice has shown that the larger the amount of flue gas processed, the more economical the investment and operating costs of using the electrostatic precipitator.
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 static electricity occurs.
MACD is a technical indicator that uses the aggregation and separation between the short-term (usually 12-day) exponential moving flat and the long-term (commonly 26-day) exponential moving flat of ** price to make judgments on buying and selling timing. >>>More
Whether it is a flat or non-planar mirror (concave or convex mirror), the light is reflected by the mirror in accordance with the law of reflection, and the reflected light enters the eye to form vision in the retina. On a flat mirror, when a parallel beam of light touches the mirror, the whole will change direction in a parallel pattern, and the image is the same as what the eye sees.
