Analysis of Plastic Film Residue Response Based on a High-Voltage Electrostatic Field

In order to improve the recovery and pickup rates of plastic film residue, this paper introduced an experiment device for plastic film residue response in a high voltage electrostatic field. Through orthogonal experiment and single-factor experiment, we respectively studied the impacts exerted by the following factors on response rate for plastic film residue: dry degree of plastic film residue, voltage between plates, electrode plate interval, charged time, stretch degree, size and mass of plastic film residue, which factors, according to the results, have a significant influence on the response rate of plastic film residue. With response rate as an index, we analyzed orthogonal experiments at 7 factors and 3 levels, identifying the optimal parameter combination of various factors and establishing its corresponding mathematical model. By virtue of experiment results, the best parameter combination is as follows: dry plastic film residue, voltage between the plates of 35kV, electrode plate interval and length of plastic film residue both of 16cm, and the charged time of 4.57s, in which case the response rate was 96.9%. This study provides experiment supports and technical reference for the application of high-voltage electrostatic adsorption of plastic film residues.
