Preparation and application of organobentonite microbeads as retention and drainage aid
摘要
Abstract
A new type of organobentonite was prepared by adding an anionic micropolymer to Ca‐bentonite powder with the semi‐dry way .The best preparation condition and its applica‐tion on the papermaking process were studied .The results show that compared to Na‐ben‐tonite modified with sodium carbonate ,the expansion ratio and charge density of Ca‐benton‐ite w hich has a poor content of montmorillonite increase separately 21 .43% and 90% after modified with anionic micropolymer .When grinding time is 40 min and the addition of anion‐ic micropolymer is 1% by weight of Ca‐bentonite ,the organobentonite performs a best reten‐tion and drainage properties which is superior to common bentonite produced by Ciba Spe‐cialty Chemicals .In addition ,grinding content of organobentonite could reach to 50% .关键词
