MINIMIZING THE NEGATIVE EFFECT OF FLUORESCENT WHITENING AGENT ON RETENTION BY ADDING ORGANIC MICROPARTICLE

摘要：

As the degree of white water circulation improved, the fluorescent whitening agent in white water had a certain impact on the pulp and filler retention. This article analyzed the effect of fluorescent whitening agent on retention under white water closure. The results showed that, in the dual retention system of CPAM and bentonite, when adding a certain amount of fluorescent whitening agent, the pulp and filler retention sharply decreased under white water closure. But in the triple retention system of CPAM, bentonite and organic microparticle, the adverse effect of fluorescent whitening agent on retention can be minimized by adding 0.05％ organic microparticle.
