In industrial production, due to friction, stripping, extrusion and induction between objects, the surface area of objects has different electric charges. When this charge accumulation reaches a certain level, electrostatic adsorption and discharge will occur. The accumulation of electrostatic charge and discharge will be on the object of adhesion, rejection, electrostatic breakdown, human body electric shock, explosion and other industrial production caused by a great impact and damage.
The role of the static eliminator is to use air ionization to generate a large number of positive and negative charges, and fans will be positive and negative charges blown out. The formation of a positive and negative charge of airflow, the object surface with the charge neutralized.
When the surface of the object with a negative charge, it will attract the positive charge in the air current, when the surface of the object with a positive charge, it will attract the negative charge in the current, neutralize the static electricity on the surface of the object, to achieve the purpose of eliminating static electricity.
Static electricity eliminator
Static eliminator by the high-voltage power producer and discharge electrodes, through the tip of the high-voltage corona discharge will be ionized into a large number of positive and negative ions and the object surface of the electrostatic discharge. When the discharge electrode is negative, electrons are repelled, protons are attracted and neutralized, and eventually a large number of negative ions are produced.
According to different corona discharge, static eliminator is mainly divided into the following types:
First, AC corona products AC high-voltage generator 220V input voltage to 7KV-10KV, discharge electrodes to 50Hz alternating frequency of positive and negative voltage, a strong electric field generated between the discharge electrode and the grounding electrode, ionizing air molecules, the tip of the discharge electrodes alternately generate positive and negative ions. When the surface of the charged object is positively charged, the negative ions are neutralized, and vice versa, if the surface is negatively charged, the positive ions are neutralized. AC corona products must be grounded to work properly, but some positive and negative ions will be directed to the ground because of grounding, therefore, the ability to neutralize static electricity is a little less, but the structure is simple, the balance of positive and negative ions is good, and the price is economical.
AC corona products - AC ionization fan
Second, DC corona products DC high-voltage producer 220V input voltage increases, positive and negative voltage output respectively, strong electric field generated between the positive and negative discharge electrodes, ionizing air molecules, positive discharge electrode tip produces positive ions, negative discharge electrode tip produces negative ions, positive and negative ions produced by the surface of the object to neutralize static, neutralize negative ions, and vice versa, if the surface of the negative potential, neutralize positive ions. Without the need of grounding, DC Corona products can generate positive and negative ions, and the positive and negative ions acting on the surface of the object are sufficient to neutralize the static electricity at a very fast speed.
DC Corona Products--Direct Current Ionizers
Pulse DC corona pulse DC high-voltage producer 220V input voltage rises, in the discharge electrode output positive and negative voltage 4-6 seconds, alternately produce positive and negative ions. When the surface of the charged object is positively charged, the negative ions are neutralized; conversely, if the surface is negatively charged, the positive ions are neutralized. Because the switching cycle of pulsed DC positive and negative ions is 200-300 times longer than that of AC static electricity eliminator, therefore, positive and negative ions themselves will not be neutralized, positive and negative ions do not need to be grounded and lost, the switching cycle can be adjusted according to the distance of the static object, the distance is long, the switching cycle is long, and the distance is close to it, the time is short. Pulse DC static eliminator can also be achieved without a fan in the case of long distance.
