Static electricity is a static charge. When the charge accumulates on an object or on the surface, static electricity is formed, and the charge is divided into two types: positive charge and negative charge, that is, the electrostatic phenomenon is also divided into two kinds: positive static electricity and negative static electricity.

When the positive charge accumulates on an object, positive static electricity is formed. When the negative charge is accumulated on an object, negative static electricity is formed. However, whether it is positive static electricity or negative static electricity, when the electrostatic object contacts a zero-potential object (grounding A charge transfer occurs when an object or an object with a potential difference from it, is a spark discharge phenomenon that we commonly see.

People often encounter this phenomenon in their daily lives: when they undress and sleep at night, they often hear buzzing noises in the dark, and they are accompanied by blue light. When they shake hands and meet each other, they suddenly feel fingertips The sting is shocking; in the morning, when the hair is combed up, the hair will often “float” and become more chaotic.

Hazard from Electrostatic Gravitation (ESA):

(1) Electronic industry: Adsorption of dust, causing contamination of integrated circuits and semiconductor components, greatly reducing the yield.

(2) Film and plastics industry: Films or films are not wound together; film and CD plastic disks are contaminated with dust and affect quality.

(3) Paper-making and printing industry: The paper is not rewinded, overprinting is inaccurate, suction is serious, and even paper is stuck, which affects production.

(4) Textile industry: Causes damages such as the fluttering of roots, the tangling of flowers, and the entanglement of yarns.

The harm of static electricity is obvious to all, and now more and more manufacturers have begun to implement various levels of anti-static measures and projects.

However, we must realize that perfect and effective anti-static engineering must be developed in accordance with the actual conditions of different companies and different operating targets. Anti-static measures should be systematic and comprehensive. Otherwise, they may be less effective and even cause destructive reactions.
