Description
Изобретеиие относитс к области целлюлозно-бумажной промышленности.The invention relates to the pulp and paper industry.
Известен способ подготовки бумажной массы путем размола волокна, проклейки и наполнени каолином. Однако при таком способе нарушаетс стабильность проклейки.There is a known method for preparing paper pulp by grinding the fiber, sizing and filling with kaolin. However, with this method, the sizing stability is disturbed.
Цель изобретени - снизить ослабл ющее действие наполнител па проклейку бумаги.The purpose of the invention is to reduce the weakening effect of the filler on paper sizing.
Достигаетс это тем, что каолин зар жают до зар да плюс 7-8 ми путе.м обработки водпы .м раствором сульфата алюмини и ввод т пспосредственпо перед отлпвом бумаги.This is achieved by the fact that kaolin is charged to a charge plus 7-8 mi by water treatment with a solution of aluminum sulphate and introduced directly in front of paper.
В максимально разбавленную бумажную массу ввод т положительно зар женный наполнитель . Целесообразно использовать каолип сухого обогащени . Дл этого каолин с зар до.м минус 5-6 ми обрабатывают водным растворо.м сульфата алюмини до получени его с зар дом плюс 7-8 MV и ввод т перед напускным щиком бумагоделательной машины.Positively charged filler is introduced into the most diluted pulp. It is advisable to use kaolip dry dressing. For this purpose, kaolin with charge up to minus 5-6 mi is treated with an aqueous solution of aluminum sulphate to obtain it with a charge of plus 7-8 MV and is introduced in front of the discharge box of the paper machine.
Способ позвол ет стабилизировать и повысить проклейку бумаги в 2-2,5 раза по сравнеппю с известным при одинаковом расходе проклеивающих и наполн ющих материалов.The method makes it possible to stabilize and increase the sizing of paper by 2–2.5 times in comparison with the known at the same consumption of sizing and filling materials.
Пред.мет изобретени Prev Invention
Способ подготовки бу.мажной массы путем раз.мола волокна, проклейки и наполнени каолином, отличающийс тем, что, с целью снижени ослабл ющего действи наполнител на проклейку бумаги, каолин зар жают до зар да плюс 7-8 MV путем обработки водным раствором сульфата алюмини и ввод т непосредственно перед отливом бумаги.The method of preparing the pulp by grinding fiber, sizing and filling with kaolin, characterized in that, in order to reduce the weakening effect of the filler on the sizing of paper, the kaolin is charged to charge plus 7-8 MV by treatment with an aqueous solution of aluminum sulfate and is inserted just before the paper is drained.
