Antistatic Systems
Kiepe offers a dedicated and specialized program of solutions to neutralize static electricity and solve the problems of the most varied and complex applications.
WHAT ARE THE EFFECTS OF STATIC ELECTRICITY?
Static electricity is a phenomenon that originates from the accumulation of electrical charge on the surface of materials, which occurs especially on dielectric and non-conductive materials, such as plastic, glass, paper and other insulating bodies. This phenomenon, typically caused by friction, rubbing, heat, tension, low humidity, often generates major problems in production processes. The most common effects of static electricity with opposite polarities are the magnetization of surfaces that stick to one another or the agglomeration of granules and powders. In the presence of electrical charges with the same polarity, a repulsion occurs between the elements, another situation that can have undesirable effects.
The presence of electrostatic charges can also cause electrical discharges, often very strong, which can have consequences for operators or cause accidents or explosions.
The industries most affected by such problems are mainly plastics, packaging and packaging, textiles, chemicals, paper and graphic arts. The unwanted presence of static electricity can be nullified very effectively by means of antistatic systems, which allow you to remove electrostatic fields by ionizing the air.
HOW DO ANTISTATIC SYSTEMS WORK?
In conditions of electrical equilibrium the atoms contain the same number of positive (protons) and negative (electrons) electric charges. When inside the atoms there is an excess or a lack of electrons there is an electric charge. Negative electric charges are due to an excess of electrons (negative ions), positive charges to their lack (positive ions). It is necessary to bring the atoms back to a condition of electrical equilibrium to cancel the electrostatic charge it.
The neutralization can take place by having an external source of ions and electrons that allows to stabilize the atoms of the material. This external source of ionic elements can be obtained by causing the ionization of the air, hence the release of the ions and electrons necessary for the neutralization of the charges.
Among the possible air ionization procedures, the simplest, most practical to implement and which offers excellent performance, is the so-called “tip effect”. It consists in delivering a high electrical voltage to a tip placed in front of a grounded mass. In this way an intense electric field is generated which causes an ionic alteration in the surrounding air. This alteration generates free ions and electrons. The positive electric charges released into the air are attracted to the negative ones of the charged mass and vice versa, to restore their balance. In this way the electrostatic charge is eliminated.
IONIZATION TECHNOLOGY TO GENERATE ELECTROSTATIC CHARGES
In other contexts, static electricity can be exploited in an advantageous way. The adherence caused by opposing charges can facilitate some processes, reducing time and improving quality. This is the case, for example, of particular processes of painting or surface treatment, extrusion of films, laminates, labeling.
