Abstract

Inventia se refera la un aparat si la o metoda pentru diluarea solutiilor de polimer de concentratie cunoscuta, pîna la o concentratie ealeasa dinainte, fara o degradare concomitenta sau o subtiere a polimerului continut în solutie. Aparatul este format dintr-o camera alungita, preferabil în forma de cilsindru sau tub, continand statii de dispersare a solutiei de polimer, aranjate de-a lungul camerei si distantate între ele. Statiile de dispesare cuprin cel putin o placa de ecran perforata. Perforatiile placilor sau a ecranelor se micsoreaza ca dimensiune pe masura ce solutia de polimer si diluantul solutiei trec spre directia de iesire sau de descarcare a camerei. Dispozitivele de controlul curgerii sînt asezate, de preferinta, între una sau mai multe din statiile de dispersie. în concordanta cu aspectele metodei din prezenta inventie, solutia de polimer de concentratie cunoscuta este dispersata succesiv într-un mod care da posibilitatea cantitatilor crescute de diluant fa fie absorbite de solutia de polimer pîna cînd concentratoia polimerului în soluta finala stinge concentratioa mai scazuta dinainte stabilita.
