Abstract

The invention discloses a calibration method for elimination time of an ion fan. The calibration method comprises steps of calibrating elimination time of an ion fan by a standard charging plate detector, charging positive and negative charges on a plate capacitor through a high-voltage generator to obtain static elimination time; and then calibrating ion balance including recording calibration results and determining re-calibration intervals. According to the calibration method for elimination time of the ion fan provided by the invention, by arrangement of the ion fan, a work plane and capacitor plates, the plate capacitor is charged with the positive and negative charges by the high-voltage generator, and the ion balance is calibrated to uniformly regulate the static elimination time ofthe ion fan, thereby reducing error of the static elimination time, improving measurement accuracy of the ion fan, and making the calibration method suitable for first calibration, subsequent calibration and in-use inspection of the ion fan neutralizing static charges in the air.

Description

technical field [0001] The invention relates to the technical field of ion blowers, in particular to a method for calibrating the elimination time of ion blowers. Background technique [0002] The function of the ion fan is to suppress electrostatic electrification. The neutralization capacity of the ion fan can be measured on a device that simulates electrostatic electrification. Therefore, an analog electrostatic electrification device is generally used to evaluate the working effect of the ion fan. It is not easy to dynamically simulate the electrostatic electrification process, because its constant current source requires an output voltage of hundreds of volts, and a high-accuracy small current measuring instrument is also required. Static simulation of electrostatic charge is relatively easy, only a flat capacitor is needed, and it is equivalent to use the decay of electrostatic charge to simulate the electrification process of static electricity. The so-called decay r...
