What is Static Electricity?

Static electricity is generated when two insulating materials in motion come into contact with each other and one material transfers electrons to the other. This creates an excess of electrons in one surface and a deficit in the other.

Surfaces Charge

The surface layer of electrically insulating material such as plastics, paper or synthetic textiles is normally not uploaded but can be by:

  • Friction – the surface of the material moves towards another material of the same or different type.
  • Pressing – The pressure provides an electron transfer when the material runs, for example, between two rolls
  • Separation – for example, when transferring a plastic film to a roll.

All these events can cause an imbalance in the material’s electrical charge. The surfaces become negative and positively charged, respectively. Because the materials are electrically insulating, the charge remains, it cannot be diverted by itself. Hence “static”.

Static Electricity Generates Production Problems

The electric charge’s capacity to attract particles with opposite polarity or repel charge with the same polarity, can cause serious problems:

  • Production and production capacity. Static electricity causes disruptions and downtime in production. The machines cannot run at the speed at which they are capable, with lower production rates and reduced profitability as a result.
  • Quality. Electrostatic clogging of dust and dirt is a serious problem in quality-sensitive industries. The result is defective products and extensive wastage.
  • Personnel security. Staff may get zapped during manufacturing, which is very unpleasant but may not be dangerous in itself. However, the secondary effects are that, because of the shocks, accidents occur in the machines.
  • Damage to control systems and components. Static discharge damages sensors, control scales, printers, metal detectors and similar equipment.

NoStatic provides systems that eliminate all these problems.

Recommendations

Friction press or separation can cause an imbalance so that one surface layer becomes positive and the other negatively charged.

An ion is an atom or molecule that has excess or deficit on electrons resulting in a positive or negative electrical charge.

In the same way, a surface of an electrically insulating material can be electrically charged if there are atoms or molecules whose electrons have been added or lost.

The electrically charged surface of an insulating material can be neutralised by ionized air. The ions are drawn to charges of opposite polarity on the surface and attach very close to these charges. This creates a net effect of zero charging in the material, thus eliminating the problem.
