Poly Dimethyl Diallyl Ammonium Chloride,PolyDADMAC - 40%

Poly (Dimethyl Diallyl Ammonium Chloride),PolyDADMAC

CAS No.: 26062-79-3
Molecular Formula: (C8H16ClN) n Molecular Weight: 210000
Structural Formula:


Property: PolyDADMAC contains strong cationic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the waste water through electro-neutralization and bridging adsorption. PolyDADMAC is very effective in flocculating, decolouring, killing algae and removing organics. PolyDADMAC enjoys small dosage but can cause big flocs, rapid precipitation and low turbidity residue. PolyDADMAC is adaptable to wide range of pH value, between 0.5 and 1.4. PolyDADMAC is smelless, tasteless and harmless.

Usage:: When used alone, PolyDADMAC should be diluted to the concentration of 0.5%-0.05% (based on solid content). When PolyDADMAC be used to treat different source water or waste water, the dosage is based on the turbidity and the concentration of the water. The most economical dosage is based on the trial. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the other chemicals in the water and the flocs can not be broken. It is better to dose the product continuously.

PolyDADMAC can be used in water treatment (drinking and waste-water), textiles, cosmetics, mining(coal, gold, diamonds etc.), paper-making, soil treatment, the oil industry, etc.

Package and Storage:PolyDADMAC is packaged in 200kg plastic drums, or according to client order. PolyDADMAC should be sealed and stored in a dry and cool place. In this way, PolyDADMAC can be stored for two years without losing its effect. If there appears stratification after the long-term storage, PolyDADMAC can be mixed before being used.
