FLOTATION DEINKING AGENTS FOR ONP RECLAIMING

摘要

In this article, conditions for ONP chemical deinking were optimized firstly, and then on the optimized conditions deinking performances of some series surfactants were discussed. Pluronic block copolyether did not have good deinking performances, polyoxyethylene alkyl ether,polyoxyethylene carboxylate and polyoxyethyleneoxypropylene alkyl ether could be used as one component of flotation deinking agents for ONP.
