What is the cause of static electricity from plastic materials?

Static electricity is a relatively static charge, generally refers to the positive and negative charges on the surface of the object due to the friction between different plastic materials .

Second, why does static electricity discharge?

That is, the movement of the electrostatic charge between the objects having different electrostatic potentials due to direct contact or electrostatic induction generally refers to the phenomenon of discharge of the medium in the plastic raw material when the energy of the electrostatic field reaches a certain level.

Third, the reason for the static electricity generated by the friction of plastic raw materials:

1. The microscopic reason is because of the theory of atomic physics. When electricity is neutral, the material is in the form of electrical balance. Because the amount of electrons generated by the contact of different material atoms will cause the material to lose its electrical balance, and then there will be static electricity.

2, the macroscopic reasons are mainly: the friction between the objects generates heat, which greatly stimulates the transfer between electrons; the mutual transfer of electrons generated when the objects touch and separate; electromagnetic induction will further cause The uneven distribution of the charge on the surface of the object; the result of the combined action of friction and electromagnetic induction.
