How to discharge static electricity
After measuring static electricity and finding it, countermeasures are required. So, how to eliminate the static electricity that has been generated? When the object is a conductor such as metal, grounding is one of the countermeasures.
The principle of grounding to eliminate static electricity
When the object is a conductor, static electricity can be eliminated simply by grounding it. For specifics on grounding, see the previous chapter "Easyness of Static Electricity Generation with Different Materials".
Grounding is a countermeasure against static electricity that is common in everyday life. For example, static elimination panels in self-service gas stations. The static elimination plate is directly grounded, and the static electricity carried by the human body will be guided to the ground through the grounding when touched by hand. In this way, the accident of igniting carbureted gasoline due to the discharge spark can be effectively prevented.
Production equipment also uses this principle. Static electricity can be eliminated simply by grounding the device.
【Features】
Just ground it, very simple.
Very effective for conductors such as metals.
【Precautions】
Not valid for insulators such as resin.
Care should be taken to avoid grounding, disconnection of connected parts, contamination, etc.
Anti-static floor material
In carpets, mats, floors, there are materials made of antistatic materials. Using this material for on-site floors where electrostatic countermeasures are required can prevent workers and equipment from being electrified.
Using conductive material, the principle is the same as grounding. It is used for electrostatic countermeasures against objects that directly touch the floor, such as workbenches and storage racks.
【Effect】
By laying a mat on the table or floor, the static electricity of the operator and the workbench is eliminated.
【Precautions】
Deterioration over time requires regular maintenance
