Title (DE) VERFAHREN ZUR HERSTELLUNG EINES ORGANISCHEN VERDICKUNGS- UND SUSPENSIONSHILFSMITTELS
(EN) PROCESS FOR PRODUCING AN ORGANIC THICKENING AND SUSPENSION AGENT
(FR) PROCEDE DE PRODUCTION D'UN AUXILIAIRE D'EPAISSISSEMENT ET DE SUSPENSION ORGANIQUE
Abstract:
(DE) Es wird ein organisches Verdickungs- und Suspensionshilfsmittel hergestellt. Dazu wird in einer Scheibenmühle mit hartmineralischen gekörnten Mahlscheiben (11, 12) eine Suspension aus organischen Faserstoffen mit fibrillärer Faserstruktur mehrfach bei erhöhter Temperatur und erhöhtem Druck gemahlen.
(EN) An organic thickening and suspension agent is produced as follows: a suspension of organic fibre materials with fibrillated fibre structure is repeatedly ground under conditions of raised temperature and pressure in a disk mill with grinding disks (11, 12) provided with hard mineral granules.
(FR) Un auxiliaire d'épaississement et de suspension organique est produit de la manière suivante: une suspension en matières fibreuses organiques de structure fibrillaire est broyée à plusieurs reprises à des température et pression élevées dans un broyeur pourvu de disques (11, 12) ayant une grainure de minéraux durs.
