Compared with toner coloring, masterbatch coloring has the following obvious advantages:
(1) it improves the environmental pollution caused by the flying of colored powder. It is easy to change colors in the process of use, and there is no need for special cleaning of the hopper of the extruder, which makes it more convenient.
(2) strong pertinence and correct color matching.Because of the masterbatch factory has to apply the performance of the resin in the process of manufacturing, reasonably select the pigment (dye), additives, processing equipment, processing technology, different batches of toner in the process of production may have off color, timely modification, complementary color, factory inspection again, therefore, can guarantee the same brand of masterbatch, before and after the two batch of color remained relatively stable.
(3) the use of color masterbatch can reduce the resin property aging caused by the secondary processing of plastic products, and is conducive to the improvement of the service life of plastic products.
The biggest advantage of using color masterbatch is: in the process of processing, pigment under the action of additives, color masterbatch through full mixing and carrier resin completely combined.In use, according to a certain proportion in the resin to be processed, color master quickly into the role, and the resin to recognize "in-laws".Affinity - compatibility is significantly better than toner coloring, therefore, for the production of film and spinning products manufacturers, more can be realized.
Of course, color masterbatch coloring also has its limitations, due to the addition of less, plastic products processing time is short, limited by the extruder screw lengthen diameter ratio, color masterbatch dispersion is often not as good as the color powder.More than a manufacturing process, dyeing costs must be higher than toner coloring.The carrier in the color masterbatch is different from the performance of the resin needed to be colored, the surface of plastic products will often appear unscattered points, spots, patterns, so the use of color masterbatch due to its compatibility and dispersion is limited, the production of color masterbatch requires a minimum order quantity, not suitable for single less non-universal color more injection parts production.
