The commonly used masterbatch technology is a wet process.The masterbatch is ground,phase-inverted,washed,dried,and granulated.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 properties of the sanding slurry,determining the solid content of the sanding slurry,and measuring the fineness of the colorant.project.

　　The masterbatch is generally composed of three parts.The colorant carrier dispersant is mixed and crushed by a high-speed mixer,and is extruded and granulated.The masterbatch has high concentration,good dispersibility and cleanness during plastic processing, and so on.
