(FR) PROCÉDÉ DE POST-RÉTICULATION THERMIQUE SUPERFICIELLE DANS UN ÉCHANGEUR THERMIQUE À TAMBOUR À VIS HÉLICOÏDALE CONTRAROTATIVE
Abstract: front page image
(DE)Verfahren zur thermischen Oberflächennachvernetzung wasserabsorbierender Polymerpartikel, wobei die Polymerpartikel mit einer wässrigen Lösung beschichtet, die beschichteten Polymerpartikel deagglomeriert und die deagglomerierten Polymerpartikel mittels eines Trommelwärmetauschers mit inverser Schneckenwendel thermisch oberflächennachvernetzt werden.
(EN)The invention relates to a method for the thermal surface post-crosslinking of water-absorbing polymer particles, wherein the polymer particles are coated with an aqueous solution, the coated polymer particles are disaggregated, and the disaggregated polymer particles are thermally surface post-crosslinked by means of a drum-type heat exchanger having an inverse screw flight.
(FR)L'invention concerne un procédé de post-réticulation thermique superficielle de particules de polymère absorbant l'eau. Les particules de polymère sont revêtues d'une solution aqueuse, les particules de polymère revêtues sont désagglomérées et les particules de polymère désagglomérées sont soumises à une post-réticulation thermique superficielle au moyen d'un échangeur thermique à tambour à vis hélicoïdale contrarotative.
