Description
Изобретение относитс к целлюлозно-бумажной промышленности, в частности к технологии подготовки активного сорбента из природных алюмосиликатов (бентонитов) - палыгорскита и его природной смеси с монтмориллонитом , примен емых в производствеThe invention relates to the pulp and paper industry, in particular to the technology of preparing the active sorbent from natural aluminosilicates (bentonites) - palygorskite and its natural mixture with montmorillonite used in the manufacture
электроизол ционной бумаги и дл очистки жидких диэлектриков.electrical insulation paper and for cleaning liquid dielectrics.
Цель изобретени - повышение выхода сорбента при одновременном снижении расхода флокул нта.The purpose of the invention is to increase the sorbent yield while reducing the flow rate of flocculant.
Сущность изобретени заключаетс в том, что согласно способу подготов ки сорбента дл изготовлени электроизол ционной бумаги, включающему приготовление суспензии природного алюмосиликата и его очистку от примесей одновалентных ионов путем осаждени флокул нтом - полиакриламидом с последующей промывкой деионизированной водой, перед осаждением алюмосиликата полиакриламидом н суспензию ввод ацетат цинка или магни в количестве 0,03-0,08% от массы исходного алюмосиликата .The essence of the invention is that according to the method of preparing a sorbent for the manufacture of electrical insulating paper, including preparing a suspension of natural aluminosilicate and cleaning it from monovalent ion impurities by precipitating with flocculant polyacrylamide zinc or magnesium in the amount of 0.03-0.08% by weight of the original aluminosilicate.
Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.
В гидроразбивателе диспергируют природный алюмосиликат - палыгорски с использованием деионизированной воды. В процессе диспергировани в суспензию палыгорскита ввод т ацета цинка или магни в количестве 0,03- 0,08% от массы исходного палыгорскита . Полученную суспензию с концентрацией 60-66 г/л фильтруют на нутч- фильтрах и очищают от песка на цент риклинерах. Затем в приготовленную суспензию добавл ют дл коагул ции раствор полиакриламида концентрацие 0,1% до полного осаждени палыгорск A natural aluminosilicate - Palygorski is dispersed in the pulper using deionized water. In the dispersion process, zinc or magnesium acetic acid is introduced into the palygorskite suspension in an amount of 0.03-0.08% by weight of the original palygorskite. The resulting suspension with a concentration of 60-66 g / l is filtered on suction filters and cleaned of sand on centrinders. Then, in the prepared suspension, a solution of polyacrylamide concentration of 0.1% is added to coagulate until complete precipitation of the Palygorsk
способа. way.
та. После осаждени палыгорскита воду сливают, а полученный осадок промывают гор чей (50-60°С) деионизированной водой с целью удалени из него водорастворимых примесей органического и неорганического осстава. Конец промывки контролируют по показател м рН и удельной электрической проводимости водной выт жки.that After the palygorskite precipitates, the water is drained, and the resulting precipitate is washed with hot (50-60 ° C) deionized water in order to remove water-soluble organic and inorganic organic matter impurities from it. The end of the wash is monitored by pH and specific electrical conductivity of the aqueous extract.
Промытый сорбент обезвоживают на центрифуге.The washed sorbent is dehydrated in a centrifuge.
В таблице приведены конкретные примеры осуществлени предлагаемогоThe table shows specific examples of the proposed
способа. way.
Как видно из таблицы, введение в суспензию алюмосиликата ацетата цинка и магни в количестве 0,03 - 0,08 мас.% от исходного алюмосиликата по сравнению с прототипом увеличивает выход сорбента на 10-20% и снижает расход полиакриламида на 70-80%.As can be seen from the table, the introduction into the suspension of aluminosilicate zinc acetate and magnesium in the amount of 0.03 - 0.08 wt.% From the original aluminosilicate in comparison with the prototype increases the sorbent yield by 10-20% and reduces the consumption of polyacrylamide by 70-80%.
