▎ 摘  要

NOVELTY - Granulating antistatic plastics comprises (1) cleaning up the mixing barrel, (2) drying and dehydrating the granular resin, (3) providing the dried and dehydrated granular resin into the mixing barrel, stirring and heating up, (4) providing lubricant, flow improver, antioxidant and coupling agent into the mixing barrel of step (3), stirring and raising the temperature, (5) continuing to providing the flow improver, lubricant, dispersant and conductive filler into the mixing tank of step (4), and discharging after stirring, (6) adding the mixed materials into the twin-screw extruder, extruding and granulating, (7) drying the particles and (8) entering dried particles to the single-screw injection molding machine. USE - The granulating antistatic plastics is useful for injection molding. ADVANTAGE - The method: makes the mixing of materials more uniform; improves the antistatic performance of the product; and reduces the influence of conductive fillers on the mechanical properties of plastic products.
