Do you know why brushes can eliminate static electricity?

Many customers are wondering why brushes can eliminate static electricity, while mesh rollers cannot? What material is your electrostatic brush made of? Why is the effect so good? Normally, the anilox roller installed on the machine is made of metal, and the effect of eliminating static electricity should be stronger than others. Why can't static electricity be eliminated?
Firstly, we need to explain how static electricity is generated. Under normal conditions, an atom has the same number of protons and electrons, and exhibits a positive and negative charge balance, thus exhibiting an uncharged state to the outside world.
However, due to external effects such as friction or various forms of energy such as kinetic energy, potential energy, thermal energy, chemical energy, etc., the positive and negative charges of atoms can become unbalanced. Friction in daily life is essentially a process of continuous contact and separation.
In some cases, static electricity can also be generated without friction, such as induction static electricity, thermoelectric and piezoelectric electricity, Hermann von Helmholtz layer, jet electricity, etc.

2、 Any two objects of different materials can generate static electricity as long as they come into contact and separate. The anilox roller and the film we print belong to two different substances. In the process of dry lamination and printing, the film and anilox roller move rapidly, and static electricity is constantly generated. How can we neutralize the electrons to eliminate static electricity?
3、 Why can a brush eliminate static electricity?
The brush is composed of superconducting fibers. Each fiber is a conductor, just like the lightning rod used in tall buildings, which forms a tip discharge effect and pours all the powerful current to the ground. Of course, the brush also needs to be grounded.
