Abstract

FIELD: paper-and-pulp industry. SUBSTANCE: invention relates to production of biologically stable paper and cardboard from craft pulp. Method includes introduction into suspension of fibrous craft pulp-based stock of polydimethylammonium chloride preliminarily treated with acid agent, advantageously ammonium sulfate, sulfuric acid, or hydrochloric acid to pH 0-4. EFFECT: increased antimicrobial activity, increased breaking strength in transverse direction, and reduced blotting capacity of paper and cardboard. 2 cl, 1 tbl

Изобретение относится к производству бумаги и картона, преимущественно из небеленой сульфатной целлюлозы, обладающих биостойкостью и предназначенных для широкого применения. Способ включает введение в суспензию волокнистого полуфабриката на основе небеленой сульфатной целлюлозы полидиметилдиаллиламмонийхлорида, предварительно обработанного кислотным агентом, предпочтительно сульфатом алюминия, или серной кислотой, или соляной кислотой, до значения pH в полученной смеси в пределах 0 - 4. Изобретение позволяет добиться стабильного увеличения антимикробной активности, увеличить разрушающее усилие в поперечном направлении и уменьшить впитываемость бумаги и картона.The invention relates to the production of paper and paperboard, mainly from unbleached sulphate pulp, possessing biostability and intended for widespread use. The method includes introducing into the suspension a fibrous semi-finished product based on unbleached sulfate cellulose of polydimethyl diallylammonium chloride pretreated with an acid agent, preferably aluminum sulfate, or sulfuric acid, or hydrochloric acid, to a pH in the resulting mixture in the range of 0-4. The invention allows to achieve a stable increase in antimicrobial activity , increase the breaking force in the transverse direction and reduce the absorption of paper and cardboard.
