Method for Coating Water-Absorbing Polymer Particles
摘要:
A process for preparing water-absorbing polymer particles by coating water-absorbing polymer particles with a particulate solid in a mixer, wherein the particulate solid is dispersed by means of a gas stream and the supply of the dispersed particulate solid in the mixer ends below the product bed surface.
