Do you know what the principle of static electricity equipment is?

Electrostatic Discharge Eliminators, also known as static eliminators, operate on the following principle. They consist of a high-voltage power supply generator and an electrode (usually in the form of an ionizing needle). By means of a high-voltage corona discharge at the tip, the air is ionized into a large number of positive and negative ions. These ions are then blown onto the surface of the object by wind to neutralize static electricity, or the static eliminator can be directly brought close to the object's surface to neutralize the static.

Electrostatic eliminators are mainly categorized into the following types:

AC Corona Discharge Products

The AC high-voltage generator boosts a 220V input voltage to over 4KV, with the electrode alternating between positive and negative voltages at a 50Hz frequency. A strong electric field is generated between the electrode and the ground electrode, ionizing air molecules and causing the electrode tips to alternate between positive and negative ions. When the surface of the charged object is positively charged, negative ions neutralize it, and conversely, if the surface is negatively charged, positive ions neutralize it. AC corona products must be grounded to operate properly, but some positive and negative ions will be directed to the ground due to grounding. However, the structure is simple and the balance of positive and negative ions is good.

2. Direct Current Corona Products

The DC high-voltage generator boosts a 220V input voltage to produce both positive and negative voltages separately. A strong electric field is generated between the positive and negative electrodes, ionizing air molecules. The positive electrode tip produces positive ions, while the negative electrode tip produces negative ions. Positive and negative ions are generated simultaneously to neutralize static electricity on surfaces. When the surface of a charged object is positively charged, negative ions neutralize it; conversely, if the surface is negatively charged, positive ions neutralize it. DC corona products can generate positive and negative ions without grounding, providing sufficient positive and negative ions on the surface of objects for rapid static electricity neutralization.
