Static ground
The conductor in the static field must reliably connects to the earth. And there must be no isolated conductor from the earth. Its total ground resistance should be less than 109Ωin any cases. When the static ground works together with other unused systems, you can make sure the resistance.
Increase the relative humidity of the air
Increasing the relative humidity of the around hydrophilic insulating materials. Then it can prevent the static. In places that do not affect product quality, increase the relative humidity around charged objects to more than 70%. Then it can be as an static safety measure.
Use static eliminators
Use a static eliminator near charged objects to ionize the air to eliminate static. But choose a proper one based on the level of the object’s static potential, medium and group.
The discharge electrode length should be 10-15cm longer than the width of the charged body. Then select the type of joint based on the distance and width of electrics.
Tips to select the location of the static eliminator
It is easy for process operation. Besides, it has a good effect to eliminate static. In addition, it is adjacent to the subsequent parts where the solvent applies. What’s more, it avoids the metal background.
Prevent the human body static
Staff should wear anti-static shoes or conductive shoes. Then use conductive ground on the working floor. Besides, staff should wear anti-static overalls.
