Kneading process equipment - GH-200 high-speed kneading machine, Beijing Plastic Machinery Plant. Operation -a, before driving clean kneader Hengshui masterbatch, comprehensive inspection and control and ensure kneader part in normal operation. b, formulated to accurately measure a variety of formulations main and auxiliary materials Masterbatch black and white, good test of raw materials. c, accurately weighed pigment and additives put into a clean mixing kneader masterbatch, time 15-30 minutes. d, parking join weighing accuracy antibacterial agents, carriers, weathering additives, processing aids and other dusheng masterbatch, driving Stir 6-10 minutes after the open spout. e, the work is completed to clean the pot. Plastic Pigment production process frequently encountered problems and solutions plastic pigment discoloration or fading Analysis: material is subjected to thermal degradation, the melt temperature is too high, too low heat resistance temperature of the toner. Workaround: additives or fillers / switch high temperature of the toner / lower cylinder temperature / check school head nozzle temperature / lower injection or screw forward speed / lower pre-plastic screw speed or feed feed rate / decrease (material in the barrel) the residence time / switch to different specifications of the injection machine embrittlement Analysis: Very long material due to thermal degradation / screw speed too high / material in the barrel residence time / screw back pressure too high / material without pre-drying / return ratio of the materials is too high? / Material was contaminated / used an inappropriate toner / at the corner part? Cut or the thread is not provided adequate transition radius / part after forming voids or nicks / hopper temperature inappropriate / mold temperature is too low / nylon plastic parts after forming the moisture content is too low? . Workaround: additives or fillers / reduce the weight of regrind / pumping tablets / check school cylinder temperature / check school head nozzle temperature / lower injection pressure / low-pressure adjustment / down? Preplasticization time? Screw back pressure / lower screw speed or feed rate when pre-plastic / tone low pressure time / reduced? Material in the barrel? Residence time.
