Ionization
There are many production processes where electrostatic charges disturb smooth operation. To eliminate static, ionizers are used. One typical field of application is the semiconductor industry where the components are extremely sensitive and can even be damaged by high electric static charges. Another example is the printing industry: Here friction between the rollers and the paper generates static. The static makes the paper cling and not move correctly through the printing machine. Especially when printing on vinyl or plastics, electrostatic charges need to be removed. In the packaging industry, plastic sleeves or foils tend to stick to each other, which can be prevented with an ionizer eliminate static. A general problem in assembling processes is the adhesion of dust and dirt particles. Contamination of workpieces can be prevented by having static eliminators neutralize and blow away undesired particles.
How does it work?
Charges are everywhere around us. Typically on a normal day basis we can store a huge amount of charge on us even though. Just to clarify things, regardless if the materials is conductive, insulative or dissipative it will still hold charges on its surface. Now you might be curious then why wouldn't we get electrocuted since everything around us is a ticking bomb that's because electric discharge will only happen when there is a potential difference.
How is it possible that this happen?
This happen due to potential difference you have to keep in mind that electricity will always flow in the lowest resistance path. After knowing this, imagine you have different potential difference at point A and B you will see a electric charge. It also depend on the strength of the charge to be able to see it significantly. We would died of electrocution because the current is so significantly small but we are able to feel the static shock. A short video clip below give you the scientific knowledge behind this principle.
