Electrostatics and industry

During the processing and finishing of materials which are insulating in one form or another (e.g. paper, textiles, glass, wood, chemicals, plastics), electrostatic charges are virtually inevitable. Charges develop when materials are processed and rub against one another, or when objects formerly in contact are suddenly separated, or when materials are joined, bonded, glued or welded. The problem lies not only with the materials, but with the energy used to move these materials. The higher the speed is, the more trouble the electrostatic charge can cause.


Handling
The difference is control. Static electricity is part of many manufacturing and finishing processes. It is an undesirable “villain” when it develops spontaneously, impacting workflow, productivity and quality. Technology must be applied to neutralize it. But it can also be deliberately generated and controlled to benefit workflow, improve quality and increase productivity.

Unwanted, destructive effects
In today’s production processes, increasingly larger material quantities need to be moved at ever increasing speeds, with the inevitable result that electrostatic charges also increase. Uncontrolled electrostatic energy causes production disruptions. Materials clinging together because of static charge attraction is just one example of static as a “villain.”.

Useful effects
This marvelous energy can also be a “hero” when it is purposely and creatively applied to improving a production process. The results are often quite remarkable! In spray-painting of cars, for example, the atomized paint can be given a charge of one polarity and the body given an opposite charge. Thus, the fine paint mist is uniformly attracted to every part of the body and little remains in the air. Even paint coverage can be assured, in a process completed faster, using less material, free of paint running or dripping.In the printing industry and in the production of films and foils, some areas can no longer survive without Electrostatic Systems.

By controlling spontaneous static – and by creatively using electrostatic energy to overcome undesirable effects in manufacturing processes, Eltex Electrostatic Systems can open new pathways to higher manufacturing quality, efficiency, productivity and profitability.
