How to judge the static electricity removal effect of ion blowers?
The static electricity removal performance of ion blowers includes: static electricity removal speed, residual voltage and positive and negative ion balance. The static electricity removal speed refers to the time to neutralize static electricity, that is, the time required to simulate the generation of 1KV (or 5KV) high voltage to 100V (or 500V), which is generally about 1S to 4.5S; the residual voltage refers to the amount of charge remaining after neutralization of static electricity, which is divided into positive and negative charges, generally around ±15V, and the ion balance refers to the equal number of positive and negative charges, which determines the amount of residual voltage in the area. After understanding these technical parameters, users can refer to the following points when choosing ion blowers:
1. Regional static electricity control: For on-site manual operations, there is no need to pursue a fast static electricity removal time, but you must choose an ion blower with a good ion balance, such as within ±10V and long-term stable performance, because this is equivalent to losing a safe ESD environment, even if the static electricity removal speed is a little slower, it doesn't matter much.
2. Regional static control: semi-automatic and semi-manual operation. For this kind of operation site, the operating speed and frequency of the equipment should be considered. When choosing, the static removal speed should be as fast as possible. Generally, about 2.5 seconds is more appropriate.
