Polyanionic cellulose, hu ua PAC, yog dej-soluble cellulose ether derivative npaj los ntawm kev hloov kho tshuaj ntawm ntuj cellulose. Nws yog ib qho tseem ceeb hauv dej-soluble cellulose ether. Nws feem ntau yog siv los ua nws cov ntsev ntsev thiab tau siv dav hauv cov roj drilling, tshwj xeeb tshaj yog nyob rau hauv cov dej brine thiab cov roj hauv ntug dej hiav txwv.
Polyanionic cellulose muaj qhov zoo thermal stability, ntsev tsis kam thiab muaj zog tiv thaiv kab mob. Cov av nkos uas tau npaj los ntawm cov khoom no muaj cov dej tsis zoo txo, inhibition thiab kub tsis kam. Nws yog dav siv nyob rau hauv roj drilling, tshwj xeeb tshaj yog brine qhov dej thiab offshore roj drilling.
