Non-woven masterbatch production knowledge summary Non-woven masterbatch production process is generally divided into: washing method, ink method, kneading method, metal soap method, the following four production processes of non-woven masterbatch The following is specifically introduced:
A. Flushing method: the pigment, water and dispersing agent are sanded to make the pigment particles smaller than 1 μm, and the pigment is transferred into the oil phase by a phase transfer method, and then dried to obtain a masterbatch. An organic solvent, as well as a corresponding solvent recovery unit, is required for phase inversion.
The process: fine color paste rinse evaporation concentrate dry and added to the carrier extrusion granulation
B. Ink method: As the name implies, it is a production method of using ink color paste in the production of masterbatch, that is, a three-roll mill is used to coat a surface of the pigment with a low molecular protective layer. The ground fine color paste is then mixed with a carrier resin, then plasticized by a two-roll mill (also called a two-roll mill), and finally granulated by a single-screw or twin-screw extruder.
The process is as follows: batch mixing coarse color paste three-roll grinding fine color paste two-roll plasticating extrusion granulation
C. Metal soap method: the pigment has a particle size of about 1 μm after grinding, and the soap liquid is added at a certain temperature, so that the surface layer of each pigment particle is uniformly wetted by the soap liquid to form a saponification liquid, as a metal salt. After the solution is added, it chemically reacts with the saponified layer on the surface of the pigment to form a protective layer of magnesium soap (magnesium stearate), so that the finely divided pigment particles do not cause flocculation, but protect a certain fineness.
D. Kneading method: After blending the pigment and the oil carrier, the pigment is lyophilized to wash the pigment from the aqueous phase into the oil phase by kneading. At the same time, the surface of the pigment is coated by an oil carrier to stabilize the pigment dispersion and prevent pigment condensation.
Strictly follow the above four non-woven masterbatch production process, the quality of the masterbatch produced will be guaranteed!
