Principle and use of static eliminator
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). The high-voltage corona discharge is used to ionize the air into a large amount of positive and negative ions, and then a large amount of positive and negative ions are blown to the surface of the object by the wind to neutralize the static electricity, or Directly neutralize static electricity by placing the static eliminator close to the surface of the object.
The static eliminators are mainly of the following types:
AC Corona New Products
The AC high voltage generator raises the 220V input voltage to above 4KV, and the discharge electrode alternates into a positive voltage and a negative voltage at a frequency of 5 Hz. A strong electric field is generated between the discharge electrode and the ground electrode, the air molecules are ionized, and the positive and negative ions are alternately generated at the tip of the discharge electrode. When the surface of the charged object is at a positive potential, the negative ions will neutralize, whereas if the surface is at a negative potential, the positive ions will neutralize. The AC corona product must be grounded for proper operation, but some positive and negative ions will be directed to the ground due to grounding, but the structure is simple and the positive and negative ions are well balanced.

DC corona products
The DC high voltage generator raises the input voltage of 220V 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, positive ions are generated at the tip of the positive electrode, and negative ions are generated at the tip of the negative discharge electrode. 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 it is negative, the positive ions will neutralize. DC corona products can generate positive and negative ions without grounding. The positive and negative ions acting on the surface of the object are sufficient, and the static electricity is neutralized very quickly.

Pulsed DC Corona Products
The pulsed DC high voltage generator raises the 220V input voltage and alternately generates positive and negative ions by alternately generating positive and negative voltages on the discharge electrode in a cycle of 4-6 seconds. When the surface of the charged object is at a positive potential, the negative ions will neutralize, and vice versa, if the surface is at a negative potential, the positive ions will neutralize. Since the pulsed DC positive and negative ions and the switching period are 200-300 times longer than the power frequency AC static eliminator, there is no self-neutralization of the positive and negative ions, and the positive and negative ions are lost without grounding, and the distance can be adjusted according to the distance of the static object to be removed. The conversion period is long, the conversion period can be long, the distance can be short, the time can be short, and the pulsed direct current static eliminator can reach the working distance of positive and negative ions without the fan.
