See below for a detailed introduction of these three production processes.
The ink method is a production method of ink color paste, which is ground by three rollers and then coated with a low molecular protective layer on the surface of the pigment, and then plasticized by two types of mechanical equipment: a two-roller plasticizer and a twin-screw extruder. and granulation. The second is the rinsing method. The pigment, water and dispersant are sanded to make the pigment particle smaller than 1 μm, and the pigment is transferred into the oil phase by the phase transfer method, and then dried to obtain the color masterbatch. The kneading method is to mix the pigment and the oily carrier, and use the lipophilic property of the pigment to obtain the black masterbatch.
