How to enhance the dispersion of pigments in colour masterbatch?
Release time：2016/9/24
Color masterbatch has become an integral part of the production of plastic products production necessary raw materials, although the industry knowledge, color masterbatch may very strange, but for our industry and familiar with, however, color masterbatch not only can be used for the production of plastic products can also be stained for plastic products.
To enhanced the dispersion of pigments in color masterbatch, can first use of the wetting pigment wetting agent, coated on the surface of the pigment, reduce pigment cohesion, reduce the fragmentation energy required for pigment aggregates, so that you can better enhance the pigment masterbatch dispersion. Can also the pigment grinding refinement, the pigment particles between freedom of movement and pigment aggregates by the surrounding medium shear stress to the aggregate particle breakage, to refine the purpose of. In addition, pigment after dispersing and disintegrating with the decrease of particle size, surface area is increased, pigment surface free energy increased instability caused by the refinement of the pigment, so on the surface of the pigment to further coating treatment, reduce the newly formed interfacial surface can prevent re agglomeration
