Briefly describe the principle of static electricity generation

In general, the corona discharge principle is used. Siamese or grounded antistatic clothing can also be released to the earth through the feet. Anti-static overalls are used to prevent static electricity on the human body, accumulate static electricity on the surface, protect against electricity at the tip, prevent damage to the components caused by static electricity, prevent the electrostatic discharge of wrist straps and anti-static shoes. Anti-static caps are also very important, and hair is easily discharged. In fact, it is so complicated to use, anti-static clothing is to use when the body movement friction without static electricity material. To strengthen the anti-static effect, it is necessary to buy some anti-static products from the anti-static company, and it is also an insulating material. Therefore, it is not possible to eliminate the electricity, and static electricity and static electricity are not generated. In order to eliminate electricity, workers in the electronics industry will wear an electrostatic loop to introduce static electricity into the ground through it.
First determine a few concepts.
First, static electricity is a static state of charge.
Second, the electrostatic field is the electric field excited by the stationary charge (relative to the observer's static charge).
Third, electrostatic discharge is an object with two different electrostatic potentials, and electrostatic charge transfer between the two objects is caused by direct contact or electrostatic field induction. After the energy of the electrostatic field reaches a certain level, the phenomenon of discharging by breaking down the medium is electrostatic discharge. Fourth, electrostatic susceptibility refers to the electrostatic discharge voltage that a component can withstand.
Fifth, electrostatic sensitive devices refer to devices that are sensitive to electrostatic discharge.
Sixth, grounding refers to an electrical connection to an object that can supply or accept a large amount of charge. Seventh, neutralization refers to the use of the opposite charge to dissipate static electricity.
Eighth, the anti-static work area refers to a work place equipped with various anti-static devices and equipment, which can limit the electrostatic potential, have clear regional boundaries and special marks and are suitable for electrostatic protection operations.
Second, we need to understand how static electricity is generated.
Static electricity can be generated by friction: In everyday life, any two different materials can be electrostatically generated after being contacted and separated, and the most common method of generating static electricity is frictional electricity generation. The better the insulation of the material, the easier it is to use triboelectricity. In addition, the separation of any two different substances after the object can also generate static electricity; but also through induction: For conductive materials, because the electrons can freely flow on its surface, such as placing it in an electric field, Because of the same sex repulsion, the opposite sex attracts, the positive and negative electrons will transfer; Also can pass the conduction: For the conductive material, because the electron can flow freely on its surface, if comes into contact with the charged object, will carry on the charge to transfer.Anti-static esd shoes.jpg                      So how to prevent static electricity? This is an imminent problem before us.
In fact, there are many ways. Such as esd grounding, esd shielding, ion neutralization, and a series of esd products, here I especially stressed that our company launched esd shoes, using the most advanced science and technology, esd effect is better than similar products
