Embodiment Construction

[0027] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0028] The sorting method of ABS, PP, HIPS, GPPS, PE plastic chips or particles of the present invention comprises the following steps:

[0029] a. Sorting out ABS plastic fragments or granules: put ABS, HIPS, PP, GPPS, PE plastic fragments or granule mixture in a container containing a sodium chloride solution with a concentration of 20%-21.5%, and the chloride in the container The preferred range of sodium solution concentration is 20%-21.5%, most preferably 20%. ABS plastic fragments or particles are deposited on the inner bottom of the container with 20%-21.5% sodium chloride solution, and HIPS, PP, GPPS, PE plastic fragments or particle mixture float on the surface layer of 20%-21.5% sodium chloride solution in the container , take out HIPS, GPPS, PP, PE plastic fragments or particle mixture, and sort out ABS plastic fragments or particles;

Abstract

The invention discloses a sorting method of ABS, PP, HIPS, GPPS and PE plastic pieces or particles. The sorting method comprises the following steps: a, sorting out the ABS plastic pieces or particles; b, sorting out the HIPS plastic pieces or particles; c, sorting out the PP plastic pieces or particles; d, sorting out the GPPS and PE plastic pieces or particles. The invention also relates to a special production line for implementing the sorting method of the ABS, PP, HIPS, GPPS and PE plastic pieces or particles. The special production line comprises an ABS sorting apparatus, a HIPS sorting apparatus, a PP sorting apparatus and a GPPS sorting apparatus.

Description

technical field [0001] The present invention relates to a sorting method of ABS, HIPS, PP, GPPS, PE plastic fragments or granules, and also relates to a special production line for realizing the sorting method of ABS, HIPS, PP, GPPS, PE plastic fragments or granules. Background technique [0002] Recycling and recycling waste plastic bottles can not only make full use of resources, but also reduce production costs. At present, the plastics with higher prices mainly include polypropylene PP, polyethylene PE, polystyrene transparent GPPS, modified polystyrene ABS and high impact polystyrene HIPS. Since these types of plastic bottles and bottle caps are difficult to distinguish with the naked eye when recycling waste plastic bottles and mineral water bottles, so that after crushing, polypropylene PP, polyethylene PE, polystyrene permeable benzene GPPS, modified polystyrene ABS and high Impact polystyrene, HIPS, etc. are mixed together, and the prices of these types of plastic ...
