Description
Изобретение относитс к целлюлозно-бумажной промьшшенности, а именно к способу подготовки бумажной массы, и может быть использовано в-производстве бумаги и картона,The invention relates to the pulp and paper industry, in particular to a method for preparing paper pulp, and can be used in the manufacture of paper and paperboard,
Целью изобретени вл етс снижение впитьшаемости при одностороннем смачивании бумаги и картона при сохранении их физико-механических показателей .The aim of the invention is to reduce the penetrability with one-sided wetting of paper and cardboard while maintaining their physico-mechanical properties.
Изобретение иллюстрируетс следующими примерами.The invention is illustrated by the following examples.
Пример 1 (прототип). К 97,5 мас.% сульфатной небеленой целлюлозы добавл ют 2 мас.% проклеивающей дисперсии, например 2%-ной парафиновой дисперсии. Массу перемешивают 2 мин, после чего добавл ют 0,5 мас.% ВПЭПА, например в виде 0,1%-ного водного раствора, и перемешивают еще 3 мин. Из полученной массы на аппарате ПБТФ изготавливают опытные образцы бумаги массой 80 г 1 м, которые затем испытывают по ГОСТам.Example 1 (prototype). To 97.5% by weight of unbleached sulphate pulp was added 2% by weight of a sizing dispersion, for example a 2% paraffin dispersion. The mass is stirred for 2 minutes, after which 0.5% by weight of VPAP is added, for example in the form of a 0.1% aqueous solution, and the mixture is stirred for another 3 minutes. From the resulting mass on the apparatus PBTF make prototypes of paper weighing 80 g 1 m, which are then tested according to GOST.
Пример 2. Состав дл изготовлени бумаги готов т аналогично примеру 1, только после введени высокомолекул рного полиэтиленполиамиАнионный проклеивающий агент - парафинова дисперси Example 2. A paper making composition is prepared analogously to example 1, only after the introduction of a high molecular weight polyethylene polyamion. Anionic sizing agent — paraffin dispersion.

Остальные примеры, выполненные аналогично примерам 1 и 2, сведены в таблицу.The remaining examples, performed similarly to examples 1 and 2, are tabulated.
Как видно из таблицы, впитываемость при одностороннем смачивании бумаги, изготовленной согласно предлагаемому способу, снизилась на 15 - 32% при сохранении физико-механических показателей .As can be seen from the table, the absorbency by one-sided wetting of paper made according to the proposed method decreased by 15–32% while maintaining the physicomechanical parameters.
