FIELD: chemical technology, cellulose industry. SUBSTANCE: method involves the addition of diluting addition to lignin at humidity 50-60% at stirring at amount 0.75-25.0% (preferably 2-5%, not less) as measured for dry matters. Lignosulfonate-containing media, for example, technical lignosulfonates, were used as diluting addition which were added to lignin at temperature at the range from the room one to 80 C. Method can be used in paper and pulp industry. EFFECT: improved method of lignin suspension preparing. 3 cl |
