Anti-static table anti-static principle knowledge

May 04, 2018

We all know that the unbalanced electron distribution causes the electrons to leave the orbit due to external forces. Any two different material objects come into contact and then separate. It is possible to generate electrostatic frictional electrification and rarely hear contact and electrification. Frictional electrification is essentially a contact and separation process that creates a positive and negative charge imbalance. Friction is a constant contact and separation process. The other body gets some negative electrons and is negatively charged. Therefore, frictional electrification is essentially contact separation and electrification. If the anti-static shelf is difficult to neutralize in the process of separation, the charge will accumulate and cause the object to be charged with static electricity. In everyday life, various types of objects may generate static electricity due to movement or friction.


Another common type of electrification is inductive electrification. When a charged object approaches an uncharged object on an antistatic workbench, negative and positive charges are induced at both ends of the uncharged conductor. When two different objects come into contact with each other, one object loses some of its charge, and the electrons transfer to another object to make it positively charged. A typical “contact separation” electrification is usually performed when a plastic film is peeled from an object. The static electricity generated by undressing in daily life is also “contact separation” electrification. In addition to the separation of the object after contact, the negative and positive charges may be induced at both ends of the uncharged conductor when the charged object approaches an uncharged object.


As we all know, the antistatic workbench is composed of molecules. The molecules are composed of atoms. The atoms have negatively charged electrons and positively charged protons. Under normal conditions, the number of protons of an atom is the same as the number of electrons, and the balance is positive and negative, so the phenomenon of no charge is exhibited externally.
