摘要
Abstract
Cationic polyacrylamide (CPAM), used as a retention and drainage aid in paper industry, has received much attention. As the white water system becomes more closed and the anionic trash in the furnish is accumulated, the anionic trash catcher (ATC) is often applied to neutralize the anionic trash. In this paper,we applied colloid titration and Zeta potential analysis to measure the charge and Zeta potential of paper furnish under the conditions of only adding CPAM and adding both CPAM and polyaluminum chloride (PAC). The underlying mechanism was studied.关键词
