Non-woven masterbatch production process is generally divided into: rinse method, ink method, kneading method, metal soap method of the four, the following non-woven masterbatch four production process to do the following specific description:
1, non-woven masterbatch production process of the washing method: the pigment, water and dispersant through the sanding, so that the pigment particles less than 1μm, and through the phase transfer method, the pigment into the oil phase, and then dried to produce color masterbatch grain. An organic solvent is required for phase conversion, and a corresponding solvent recovery unit.
Process: fine paste rinse evaporate concentrated material dry into the carrier extrusion granulation
2, ink method: As the name suggests, is used in the production of masterbatch ink color paste production methods, that is, through the three-roll grinding, the surface of the paint coated with a layer of low molecular protection layer. The finely ground paste is then mixed with the carrier resin and then plasticized by means of a two-roll mill (also known as a two-roll mill) and finally granulated by a single screw or twin screw extruder.
Process: Ingredients Mixing coarse paste three roller grinding fine paste two roll plastic extrusion extrusion granulation
3, the metal soap method: the pigment after grinding the particle size of about 1μm, and at a certain temperature by adding soap, so that each pigment particle surface layer is evenly wet by the soap to form a layer of saponification solution, when the metal salt The solution is added to react with the saponified layer on the surface of the pigment to form a protective layer of metallic soap (magnesium stearate), so that the finely divided pigment particles do not cause flocculation and protect the fineness
4, kneading method: the pigment and oily carrier is blended, the use of pigment lipophilic this feature, through the kneading of the pigment from the water into the oil phase. At the same time by the oily carrier will paint the surface of the paint, so that the pigment dispersion stability, to prevent the pigment cohesion.
