Brief introduction to three processing methods of black masterbatch:
Black masterbatch is widely used in color masterbatch and has important coloring significance in injection molding industry. There are many processing methods for black masterbatch. Next, we briefly introduce the common single screw method, twin screw method and internal mixing method of black masterbatch.
Single screw method is that after logistics mixing, it is granulated by single screw machine. With black masterbatch. With the continuous development of the industry, this process is gradually eliminated. The twin-screw method opposite to the single screw method is the same principle. The granulation is carried out by the twin-screw machine, and the carbon black concentration of the black masterbatch is 25-32%.
The third is the internal mixing method. This method is kneaded by the internal mixer, then fed into the twin-screw extruder by the feeder, and granulated by water ring or underwater. The carbon black concentration of the masterbatch is generally 40-45%. Compared with the former two, the internal mixing method is more widely used and has obvious advantages in improving the bearing capacity of the carrier to carbon black.
