What is the principle of anti-static equipment?
The static eliminator can also be called a static elimination device, and the principle is as follows. It consists of a high-voltage power generator and a discharge electrode (generally made of an ion needle), which ionizes air into a large number of positive and negative ions by a high-voltage corona discharge, and then blows a large amount of positive and negative ions to the surface of the object to neutralize static electricity, or Directly neutralize static electricity by placing the static eliminator close to the surface of the object.
The static eliminator is mainly divided into the following types of AC corona product AC high voltage generator to raise the 220V input voltage to above 4KV, the discharge electrode alternates with positive voltage and negative voltage at 50Hz frequency, and generates a strong electric field between the discharge electrode and the grounding pole. The molecules are ionized, and the tips of the electrodes alternately generate positive and negative ions. When the surface of the charged object is positive, the negative ions will neutralize. Conversely, if the surface is negative, the positive ions will neutralize. The AC corona products must be grounded to work properly, but Some positive and negative ions will be directed to the earth due to grounding, but the structure is simple and the positive and negative ions are well balanced.
The DC corona product DC high voltage generator raises the 220V input voltage and outputs positive voltage and negative voltage respectively. A strong electric field is generated between the positive and negative discharge electrodes, the air molecules are ionized, and the positive electrode is positively generated at the tip of the electrode. www.hormintech.com, Negative ion is generated at the tip of the negative electrode, and positive and negative ions are simultaneously generated to neutralize the surface of the object. When the surface of the charged object is positive, the negative ions will neutralize. Conversely, if the surface is at a negative potential, the positive ions will neutralize. The DC corona product is not required. Grounding can produce positive and negative ions, positive and negative ions acting on the surface of the object are sufficient, and the static electricity speed is very fast. The pulsed DC corona product pulse DC high voltage generator raises the 220V input voltage and outputs positive voltage in a cycle of 4-6 seconds. The negative voltage acts on the discharge electrode to alternately generate positive and negative ions. When the surface of the charged object is positive, the negative ions will neutralize. Conversely, if the surface is negative, the positive ions will neutralize. Due to the switching period of the pulsed DC positive and negative ions It is 200-300 times longer than the power frequency AC static eliminator, so there is no self-neutralization of positive and negative ions. It is necessary to ground and lose positive and negative ions, and the conversion period can be adjusted according to the distance of the static object to be removed. The distance is long, the conversion period can be long, and the distance can be short when the distance is close. The pulse DC static eliminator does not have a fan. Positive and negative ions can also reach a very long range of action.
