Causes of static electricity in plastic film

The causes of static electricity in plastic films are as follows:

1. Micro reasons. According to the theory of atomic physics, matter is in electrical equilibrium when it is electrically neutral. Due to the gain and loss of electrons generated by the contact of atoms of different substances,

substances lose their electrical balance and generate electrostatic phenomena.

2. Macro reasons. Friction between objects generates heat to stimulate electron transfer; Contact and separation between objects produce electron transfer; Electronic induction causes unbalanced distribution of electric

charges on the surface of objects; Combined effects of friction and electromagnetic induction.

plastics are all polymer materials, and the volume resistance of surface resistance is greater than 10. Therefore, it endows the plastic material with good insulation performance. And

It is for this reason that it is easy to generate static electricity, because plastics and their products are extremely possible in the production and handling, contact, separation, friction and collision, and involvement in electromagnetic induction

, it is even impossible to avoid these occasions. That brings about the cause of static electricity.
