the compatibility of black masterbatch is one of the factors that determine the quality of masterbatch. If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other infusible polymers. This will cause some unpredictable and difficult to restrain the trouble, wasting the time and raw materials of the end consumer. At this time, a primer resin can be selected to produce high-quality masterbatches, and the masterbatches have good compatibility during the melting process. High-quality masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials.
If engineering grade and strict physical properties have been specified, then special polymer black masterbatches can be obtained. Several major international masterbatch manufacturers are conducting research to produce the so-called "global universal black masterbatch. These masterbatches are widely compatible with other raw materials and have good rheology. Flexible application.
The black masterbatch technology generally used is a wet process. The masterbatch is made by grinding, inverting, washing, drying, and granulating in the water phase. only in this way can the product quality be guaranteed. In addition, when the pigment is ground, a series of color masterbatch technology tests should be performed, such as measuring the fineness of the sanding slurry, measuring the diffusion performance of the sanding slurry, determining the solid content砂光的泥浆,确定fineness of the colorant project.
The black masterbatch is generally composed of three parts. The colorant carrier dispersant is mixed by a high-speed mixer, crushed, and extruded into granules. The color masterbatch has high concentration, good dispersibility and cleanliness during the plastic processing. And other significant advantages.
