Simply put, masterbatch is pigment + carrier + additive formed colorant, with good dispersion, stability, but also to protect the health of the operator, keep the use of the environment clean, because it is very popular with people, but occasionally in use, there will be spotted water pattern phenomenon, why? And how to solve it? The following is answered by the editor for you.
1. Masterbatches contain water.
2. The length-diameter ratio of the extruder is not enough, resulting in uneven dispersion.
3. The masterbatch itself is unevenly dispersed.
4. The concentration of masterbatch colorant selected is too high, and the amount added is too small.
All in all, the quality of the masterbatch selected is not good, so in order to solve the occurrence of piebald water lines, it is necessary to select high-quality products, so that the phenomenon of piebald water lines caused by these four reasons can be fundamentally eliminated. At the same time, in order to ensure its color quality, it is necessary to do a good job of maintenance after dyeing, so that the stability of its dyeing effect can be better maintained.
