Description
Дл очистки диализом отжимного щелока в производстве искусственного волокна примен ют полупроницаемые- перепонки , приготовл емые или путем продолжительной мерсеризации плотных хлопчатобумажных тканей или путгем пергаментировани серной кислотой.For cleaning dialysis liquor in the manufacture of artificial fibers, semipermeable membranes are used, either prepared by prolonged mercerization of dense cotton fabrics or put by paper parchment with sulfuric acid.
В предлагаемом способе дл получени полупроницаемой перепонки ткань подвергают мерсеризации раствором едкогонатра концентрации 25-30% в течение суток при обыкновенной температуре, после чего промывают. Хороший результат получаетс также при обработке ткани сначала в 55-60%-ной серной кислоте в течение 10 минут и затем, после удалени кислоты, производитс мерсеризаци в едком натре вышеуказанной крнцентрации . Ткань промываетс , высушиваетс и сшиваетс в мешки дл использовани на железном каркасе дл очистки прессовых волокон.In the proposed method, to obtain a semipermeable membrane, the fabric is subjected to mercerization with a solution of an alcohol extractor of a concentration of 25-30% for 24 hours at an ordinary temperature, and then washed. A good result is also obtained by treating the tissue first with 55-60% sulfuric acid for 10 minutes and then, after removing the acid, mercerization is carried out in caustic soda of the above concentration. The fabric is washed, dried and stitched into bags for use on an iron frame for cleaning press fibers.
Предмет изобретени .The subject matter of the invention.
1.Способ приготовлени полупроницаемой перепонки, служащей дл очистки прессового щелока искусственного волокна путем диализа, отл чающийс тем, что ткань подвергают мерсеризации раствором едкого натра концентрации 25-30 « в течение суток.1. A method for preparing a semipermeable membrane used to clean the press liquor of an artificial fiber by dialysis, except that the fabric is subjected to mercerization with sodium hydroxide solution of a concentration of 25-30 "during the day.
2.Прием выполнени означенного в п. 1 способа, заключающийс в том, что перед мерсеризацией ткань пергаментируют действием 55- 60%-ной серной кислоты.2. Acceptance of the method indicated in paragraph 1, which consists in the fact that before mercerization the fabric is parchmented by the action of 55-60% sulfuric acid.
