Compared with toner coloring, black masterbatch coloring has the following obvious advantages:
1. It improves the environmental pollution and employee health problems caused by toner dust, and it is easy to change color during use, and there is no need to carry out special cleaning on the extruder hopper, which is convenient and fast.
2. Strong pertinence and correct color matching. Because the masterbatch manufacturing plant has reasonably selected pigments (dyes), additives, processing equipment, and processing technology for the performance of the applicable resin in the manufacturing process, the color difference that may be caused by different batches of toner in the production process is corrected and supplemented in time, and then inspected when leaving the factory, so it can ensure that the color of the same brand of masterbatch remains relatively stable before and after the two batches of color.
3. Compared with the plastic parts after dry dyeing and granulation of batches of resin, the use of color masterbatch can reduce the aging of resin properties caused by secondary processing of plastic products, which is conducive to the improvement of the service life of plastic products.
The advantage of using masterbatch is: in the processing process of black masterbatch manufacturer, the pigment is under the action of additives, and the masterbatch is fully mixed and completely combined with the carrier resin. When used, placed in a certain proportion of the resin to be processed, the masterbatch will quickly enter the state, and the affinity and compatibility are obviously better than toner coloring, which is more experienced for manufacturers of film and spinning products.
The disadvantages of using masterbatch are: due to the small amount of addition, the processing time of plastic products is short, and the dispersion of masterbatch is often not as good as that of toner due to the limitation of the length and diameter ratio of the extruder screw. With one more manufacturing process, the cost of dyeing must be higher than that of toner coloring. When the performance of the carrier in the black masterbatch masterbatch is different from the resin to be colored, there are often undispersed spots, spots, and patterns on the surface of plastic products, so the use of masterbatch is limited because of its compatibility and dispersion, and the production of masterbatch requires a minimum order quantity, which is not suitable for the production of injection molded parts with less than single and non-universal colors.
