PROCESS OF PREPARATION OF PULP, PROCESS OF PRODUCTION OF ABSORBENT MATERIAL AND PULP USED IN ABSORBENT PRODUCTS Russian patent published in 2002 - IPC

FIELD: wood-pulp and paper industry. SUBSTANCE: pulp capable of defibring is prepared and stock for production of absorbent material meant for inclusion in absorbent product as component is produced. In starting cellulose fibers coming in the form of aqueous suspension pH is adjusted to value 4 <pH <8. Certain water-soluble non-polymer aluminum salt is added to starting material. Specified salt forms at specified value of pH any hydrate aluminum complex of type A1(OH)xn

, where n is number between 1 and 3 and x=0, + or 2+. Above-mentioned salt exerts in aqueous solution effect on cellulose fibers in suspension with specified pH in the course of time of 2 min as minimum. After it fibrous mass is shaped in the form of panel which is dewatered and dried. EFFECT: raised efficiency of defibring of cellulose in dry state, decreased energy consumption for separation of fibers, considerably diminished demand for break-down agents, produced pulp displays good absorption capability and high rate of absorption. 16 cl, 8 dwg, 10 tbl
