Product Introduction
1. The company's papermaking dispersant is mainly the front-stage dispersant (PAAS), a modified branched-chain low molecular weight polypropionate organic dispersant. This product is suitable for the front-stage dispersant of pigments during grinding and is also applicable for pigment preparation.
2. The front-stage dispersant during grinding (PAAS) is conducive to the dispersion and stability of particles in filler grinding, and improves the rheological property and fluidity of emulsion or slurry. It has a very good grinding and dispersion effect. When used in the mill, it can effectively transmit mechanical shear force to calcium carbonate particles to increase grinding efficiency and productivity, or finer calcium carbonate particles can be obtained under the same wet grinding conditions.
