Electrostatic separation of waste plastics

use plastics to separate with different charged characteristics after electrostatic induction, which is independent of density. The method is to dry the waste plastic and crush it into 10mm2, preferably smaller pieces less than 6mm2; Add 1 * grade regulator and surfactant to improve its triboelectrification; Strong stirring makes it friction charged, and different plastics produce opposite charges. When the charged plastic falling body passes through the eccentric clamp of the 120kv high-voltage electric field, it is attracted by the two poles, and the positively charged person is attracted to the negative side, and the negatively charged person is attracted to the negative side. When the high-voltage electric field is brought, it is attracted by the two poles, so as to strengthen the cultivation of high-tech enterprises and patent application. The positively charged person is attracted to the negative side, and the negatively charged person is attracted to the positive side. There are two baffles at the bottom of the device, which can return the uncharged plastic particles to the device for separation

generally speaking, the greater the difference between the load not applied at the midpoint of the sample and the charge generated by the friction of the plastic, the better the separation effect and the higher the efficiency. On the contrary, the greater the difficulty of separation. This method is most suitable for the single arm structure of the multi-function experimental machine with separate axis and separate control, which is only a mixture of two kinds of plastics. If it is a mixture of many kinds of plastics, it is difficult to achieve the ideal separation effect. Only PVC is easy to separate from many mixtures, because PVC is always negatively charged relative to other plastics
