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, Hebei masterbatch, colorant heat temperature is too low. 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. Production process frequently encountered problems and solutions of the three elements of the program colors: colors include three elements: a light source, object and eyes. 1. In the light of different light sources have different spectral energy distribution; therefore an object from different sources resulting color will be different. 2. The body color reflective index and the material surface in different waves generated will be different, masterbatch, color also take into account our sight angle change. 3. eye human eye can see light waves generally is 380-760 nm. Different waves generated by reflection will be different, King County masterbatch, and then produce different colors. l three primary colors of light: the light of the three primary colors (RGB) are red (red), green (green), blue (blue).
