1. Ink method of nylon masterbatch, Wang Wensheng is the method of adopting the ink color paste in the masterbatch, that is, the surface of the pigment is coated with a low-molecular cover layer through three-roll grinding. The ground fine color paste is then mixed with the carrier resin, and then the plasticization is stopped by a two-roll mill, also called two-roll mill, and the granulation is stopped by a single-screw or twin-screw extruder.

2. The scouring method of nylon masterbatch is that the pigment, water and the dispersing agent are sanded to make the pigment particles less than 1 μm, and the pigment is transferred into the oil phase by phase transfer method, and then dried to obtain the masterbatch. Inductive assembly is required for the phase inversion with an inorganic solvent and a responsive solvent.

3. The kneading of the nylon masterbatch is a feature of blending the pigment with the oily carrier and applying the pigment oleophilic, and kneading the pigment to wash the pigment from the aqueous phase into the oil phase. At the same time, the surface of the pigment is coated by an oily carrier to make the pigments loose and stable, and to avoid agglomeration of the pigment.

4. The metal soap method of nylon masterbatch is that the particle size reaches 1μm after grinding, and participates in the soap at a certain temperature so that the surface layer of each pigment particle is evenly wetted by the soap to form a saponification liquid. When the metal salt solution participates and chemically reacts with the saponified layer on the surface of the pigment to produce a layer of metallic soap, magnesium stearate, so that the finely pulverized pigment particles will not cause flocculation, and the cover must be Fineness.
