The commonly used masterbatch technology is a wet process. The masterbatch is made by aqueous phase grinding, phase inversion, water washing, drying and granulation. Only the quality of the product can be guaranteed. In addition, the pigment should be subjected to a series of masterbatch technology tests, such as determining the fineness of the sanding slurry, measuring the diffusion performance of the sanding slurry, determining the solid content of the sanding slurry, and measuring the fineness of the colorant.
The masterbatch is generally composed of three parts. The colorant carrier dispersant is kneaded by a high-speed mixer, crushed, and extruded into pellets. The masterbatch has high concentration, good dispersibility and cleanness during plastic processing.
