How to eliminate static electricity during coating

01、Static electricity often causes a lot of problems in the coating process
In flammable and explosive environments, static electricity can cause the combustion and explosion of dangerous substances.
In addition, the static electricity on the coating substrate will also produce a lot of coating defects: for example, the substrate with static electricity is more likely to absorb dust and stolen goods in the environment, or it will produce defects like cracks and pinholes on the coating surface.

02/ In the coating process, static electricity is mainly caused by the following reasons
1. The substrate in the unwinding area is separated from the master coil to generate static electricity

2, the substrate friction on the roller produces static electricity

3, the rapid flow of the solution in the catheter or spraying produces static electricity

4, the stirring of the solution produces static electricity, etc

03、 How to eliminate static electricity in the coating process

1. Increase the ambient humidity without affecting the product quality

2. Ground

3. Use an electrostatic eliminator

4. Use an ion fan

5. Electrostatic cord

04、 Static elimination Tips
The installation position of the static eliminator is very critical, the static eliminator is not installed closer to the substrate the better, it is usually recommended that the static eliminator distance from the substrate should be about 2.5cm or so is the best!
