Abstract

La présente invention concerne un appareil de tamisage de dispersions aqueuses, sensibles au cisaillement de polymères. Cet appareil est caractérisé en ce que le plan du tamis 1, muni de fentes horizontales de tamisage, est incliné de 30 degrés à 70 degrés par rapport à l'horizontale et en ce que ce tamis est arrosé, pendant la filtration, par de l'eau et/ou une solution d'un produit anti-mousse au moyen de buses de pulvérisation 4. L'ensemble est enfermé dans un boîtier clos. Il est en particulier destiné au tamisage de dispersions aqueuses de polymères ayant des teneurs en matières solides comprises entre 10 et 60 % en poids, de préférence avec au moins 40 % en poids de motifs chlorure de vinyle polymérisés.
