Abstract

Inventia se refera la un procedeu de microîncapsulare a unui agent chimic biologic în care: (a) se prepara o solutie sau o dispersie a unui agent chimic biologic, într-o pasta apoasa de polihidroxi-polimer gelifiabil,ales dintre amidon, carboximeil-celuloza, dextran, xilan si alcool polivinilic, pasta avînd o concentratie de polihidroxi-polimert gelifiabil solid de circa 10...40%, într-un raport în greutate între agentul chimic biologic si polihidroxi-polimer cuprins între 1:10 si 1:1, exprimatca substante uscate, (b) se trateaza într-o singura faza, la un pH alcalin cuprins între 7,5 si 8,5 polihidroxi-polimerul cu acid boric sau un derivat de acid boric pentru obtinerea unui gel insolubil în faza continua avînd înglobate faze discontinui de agent chimic biologic, si (c) se recupereaza particulele cu curgere libera din agentul chimic biologic prin spargerea gelului în particule discrete, amestecarea particulelor cu un material de acoperire pulverulent, de preferinta amidon, faina, silice, argila si se usuca particuele astfel acoperite.
