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.
