The Latest Wet-end Control Technology by New Type Retention Aid “REALIZER FX Series”

Abstract

We have been working on developing more efficient retention aid with new concept to replace the today's main Dual Addition System of Cationic retention aid and Anionic retention aid. As a result of the effort, “AXISZ System”was successfully brought to market, “AXISZ System”consists of“REALIZER A Series”/high-performance coagulant, good for minimizing the stain of paper making machine and“REALIZER R”Series/high-performance Cationic retention aid.
“AXISZ System”is very unique and is extremely different from competitive products design. Especially, in case of Cationic-single addition, “REALIZER-R300”achieved extremely better retention that resulted in expanding its application to coating machines and board paper machines. Since then, we kept working on the development of Cationic polymers good for single addition.
As was pointed out, closed system of water and increase of waste paper ratio have brought a lot of pitch and ash. Consequently, there has been a trend that increased dosage of various kinds of chemicals for fillers. As for retention aid, there are cases that conventional dual addition system or cationic single addition cannot work well as before.
Under these circumstances, we newly developed“REALIZER FX Series”/Anionic retention aid and then, have been working on establishing the innovative retention system based on the Anionic retention aid. In this paper, we would like to show the instances of REALIZER FX System applications and dual addition system with new concept which is effective in stable fixation of various kinds of chemicals for filling in combination with“REALIZER A Series”.
