Abstract
Inventia se refera la un procedeu pentru obtiberea celuilozelor micronizate constînd în maruntirea colilor de celuloza, prepararea agentului de hidroliza, hidroliza acida, filtrare, tratament alcalin, spalar, stoarcere, uscare, destramare, sitare, însucuire, caracterizat prin aceea ca maruntirea se face pîna la o dimensiune a taiteilor de 30x5 mm, hidroliza se realizeaza cu o solutie de acid sulfuric de concentratie de 20-50% la temperaturi de 40-70 degree C, timp de 6 h, se filtreaza si se spala sub agitare continua pîna la pH neutru, se usuca prin stpoarcere pîna la o umiditate de 35-40% si se usuca cu aer cald avînd temperatura de 105 degree C pîna la o umiditate de 1-3%. Instalatia cuprinde în acest scop, un dozator cu senc, o presa snec si un uscator tip tambur rotativ.
