摘要
研究不同水份吸附级凹凸棒石粘土原矿用不同浓度稀硫酸活化,陈化时间不同,其脱色率变化情况。结果表明:陈化4h和8h,脱色效果差别不大;不同水份原矿用不同浓度稀硫酸活化,其脱色率变化较大;原矿自然水份为32%左右,用5%的稀硫酸活化时效果理想。
The different moisture absorbing rate to attapulgite clay raw mineral which should use different concentration sulphuric acid to activate and different result got with the different ageing time .From the condition of decolour ratio we can conclude: at the condition of raw moisture using sulphuric acid to activate it can absorb the effort of decolour, when 8 ageing hours or 4 hours one just get little difference; when the moisture rate 32%, 5% sulphuric acid to activate will get good result.
