Non-woven masterbatch production process!

The production process of Non-woven masterbatch is generally divided into four kinds: washing method, ink method, kneading method and metal soap method. The following is a specific introduction to the four production processes of Non-woven masterbatch.

1. Flushing method is to sand the pigment, water and dispersant to make the pigment particles less than 1μmphase transfer method, transfer the pigment to oil phase and dry on the area to produce an area. It is necessary to use organic solvents during phase conversion, and the corresponding solvent recovery and drainage.

Its process: fine color paste washing evaporation concentrate  dry into the carrier extruded granulation.

2, ink method: As the name suggests, is the production method of ink paste in the production of color masterbatch, that is, through three roller grinding, coated with a layer of low molecular protective layer on the surface of the pigment. After grinding, the fine color paste is mixed with the carrier resin, and then plasticized by a two-roll plasticizer (also known as a two-roll open mill), and finally granulated by a single or twin-screw extruder.

The process is as follows: mixing coarse color paste three roller grinding fine color paste two roller plasticizing extrusion granulation

3, metal soap method: The particle size of the pigment after grinding reaches about 1μm, and the soap liquid is added at a certain temperature, so that the surface layer of each pigment particle is evenly moistened by the soap liquid, forming a layer of saponification liquid, when the metal salt solution is added and the saponification layer on the surface of the pigment chemical reaction to produce a layer of metal soap protective layer (magnesium stearate), In this way, the pigment particles after grinding will not cause flocculation, and protect a certain fineness.

4, kneading method: After mixing pigments and oil carriers, using the characteristics of the pigment oil, the pigment is washed from the water phase into the oil phase by kneading. At the same time, the surface of the pigment is covered by an oily carrier, so that the pigment is dispersed and stable, and the pigment is prevented from condensing.
