Static electricity is so annoying!! The "secret" of eliminating static electricity is revealed~(1)
What are the common electrostatic disasters?
static spark It is easy to detonate flammable liquids, causing human body, mechanical damage, environmental disasters, etc. | interfere with wireless communication Airplanes are electrified by friction with air, moisture, dust, etc., resulting in interference with radio communications. | electrostatic adsorption of dust The electrostatic adsorption of dust results in poor or impure products during the packaging process. |
Static hazard prevention methods can be divided into five types: grounding, increasing humidity, limiting speed, antistatic materials, and static eliminators. In the industrial manufacturing process, due to the different operating environments, procedures and materials, the implementation of electrostatic hazard prevention methods will also be different.
There is no single method of electrostatic hazard prevention that can be applied to all industrial processes or situations.
Sometimes two or more electrostatic hazard prevention methods are used at the same time.
1. Ground
2. Increase humidity
3. Antistatic material
4. Static eliminator
5. Speed limit
Grounding is the most efficient and economical method. During the process, static electricity is generated by friction, induction or conduction. If the charge is accumulated on metal equipment, conductive products or people's bodies that are insulated from the ground, the accumulated charge will release energy in one discharge.

In the factory process, methods such as humidifiers, ground sprinklers, or water vapor spray are usually used. | If the conduction path is made of an insulating material (low conductivity), the electrostatic dissipation rate is low, and if the conduction path is made of a conductive material (high conductivity), the electrostatic dissipation rate is high. | Using high voltage electricity to generate charged ions in the air. Ions can neutralize the charge of electrostatically charged objects because opposite charges are attracted to each other and neutralized. | In the industrial process, two objects may generate static electricity due to friction, and gradually accumulate static electricity hazards. Therefore, reducing the friction speed can slow down the generation of static electricity. |
