FT-WA20 charge control agent is a new type of charge regulator developed by our company for the accumulation of a large amount of anionic waste in the wet end system of closed cycle papermaking white water system, which affects paper quality and causes paper defects. The appearance of this product is colorless to light yellow viscous liquid, easy to dissolve in water, good stability, and safe and non-toxic. After addition, it will combine with the anionic waste and fine materials in the pulp, neutralize soluble organic matter, neutralize the negative charges on the surface of small fibers with high charge density, balance the wet end potential, reduce the interference of anionic impurities, and promote the retention of small fibers and wet end chemical additives (such as sizing agents, dyes, reinforcing agents). And it can improve the one-way retention rate and water filtration rate of online paper material, improve the operating performance of the paper machine, extend the service life of the blanket, reduce drying steam consumption, and increase vehicle speed and production.
