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.

The Anti-swelling Mechanism of PolyDADMAC PolyDADMAC is a cationic polymer with a number of N+ perssad in its molecular structure, and the N+ perssad can exchange with the low valence cation in the clay lattice, which makes clay particles not easy to be hydrated, expand, and be transported, so it is a good organic anti-swelling agent for clay. At the same time, the compound of cationic polymer polydadmac with inorganic clay anti-swelling agents will make them complementary to each other and play a synergistic effect.

SINOFLOC polyDADMAC is liquid, cationic coagulants with different solid contents and viscosities and suitable a wide range of PH. Our products could be used in filtration applications or in combination with our other flocculants products for wastewater treatment of turbid river and tap water and also could be used in wastewater treatment (drinking and wastewater),
