Investigating the static elimination performance of the ion fan includes: removal of static electricity speed, residual voltage and positive and negative ion balance. The static elimination speed refers to the time of neutralizing static electricity, that is, the time required to reduce the high voltage from 1KV (or 5KV) to 100V (or 500V), which is generally about 1S to 4.5S; the residual voltage refers to neutralizing static electricity. The amount of charge remaining after the positive and negative charge is generally around ±15V. The ion balance is the equivalent quantity of positive and negative charges, which determines the amount of residual voltage in the area. Understand these technical parameters, when the user chooses the ion fan, you can refer to the following points:
1. Area static control: manual work on site, no need to pursue static removal time quickly, but must choose ion blower with good ion balance, such as ±10V and long-term stability, because it is equal to the safe ESD environment, even if In addition to the slower static electricity rate, it does not matter much.
2, regional static control: semi-automatic, semi-manual operation, this kind of work site should consider the operating speed and frequency of the equipment, the static electricity speed is selected as soon as possible. Generally it is suitable for about 2.5 seconds.
