Improvement of the runnabilty for paper making by "Axisz System"

Abstract

Neutral papermaking and high recycle fiber usage in recent years make papermaking more troublesome. Conversion of acid to neutral papermaking reduced popular use of alum. Increased recycled fiber usage promoted by global resource protection and environmental concern brings more foreign materials such as pitch and anionic trash in papermaking system. At Somar we have been working on wet-end improvement agent "Realizer A series" as functional coagulant which maximizes the effect of variety of wet-end chemicals. Latest polymer technology help us to develop another functional retention aids as "Realizer R series" and "Rexer FX series" which are effective in fine and ash retention. Synergistic effect of the combination of these chemicals to improve wetend performance is referred as " Axisz System". It developed by Somar will give a solution to the problems associated with wet-end operation. The new chemical assists retention of other wet-end chemicals, thus reducing total chemical usage. It also improves drainage and fiber retention. Optimization of wet-end operation using "Axisz System" can be achieved by proper selection of cationic charge, molecular weight and molecular weight distribution. It depends on stock characteristics and other chemical usage. Maximization of the effect with "Axisz System" is demonstrated.
