Static electricity does a lot of harm to people, but it also has many benefits. For example, people have applied electrostatic technology to industrial and agricultural production and life, such as dust removal, printing, spraying, flocking, sorting, seawater desalination, spraying pesticides, artificial rainfall, low-temperature freezing, spacecraft replenishment and so on.
The simplest way to eliminate the harm of static electricity is to introduce static electricity into the ground, such as grounding the equipment with wires; Install discharge brushes at the wing tip and tail of the aircraft, and use grounding tires and grounding wires on the landing gear of the aircraft; The tail of the tanker is tied with a grounding chain; In the chemical production, storage and transportation departments, it is forbidden to use chemical fiber fabrics, and it is forbidden for workers to wear chemical fiber work clothes. In daily life, we can also take some simple measures to eliminate static electricity, such as underwear, quilts, sheets, quilts and so on. It is best to use cotton fabric instead of chemical fiber; In the family room, you can often spray water and humidify it to eliminate static electricity.
