The Application of PolyDADMAC in Papermaking As a kind of water-soluble cationic polymer, PolyDADMAC has the advantages of the high density of positive charges, good water solubility, controllable molecular weight, high efficiency, no toxic, and low cost, therefore it is widely used in oil drilling, paper making, mining, textile printing and dyeing, daily-use chemical industry, sterilization, metal anti-corrosion, water treatment, and other fields. PolyDADMAC is mainly used as the standard titrant, anionic capture, and flocculant in the papermaking industry, and it can also be used in the production of conductive paper. . Used as a standard titrant With medium molecular weight and charge density, PolyDADMAC has become the standard cationic polymer in general use. However, it can only be applied when the ionic strength of the solution is low and the charge density of the measured polyelectrolyte is not too low. When the existing metal ion concentration exceeds a certain range, it is advisable to use a cationic polymer labeled with a chromogenic group for titration.
