Poly(diallyldimethylammonium chloride) is a chemical substance with the molecular formula (C8H16NCl)n. It is a strong cationic polyelectrolyte with the appearance of colourless to light yellow viscous liquid. It is safe, non-toxic, soluble in water, non-flammable, strong cohesion, good hydrolytic stability, not a gel, insensitive to pH changes, and chlorine resistant. Freezing point is about -2.8℃, specific gravity is about 1.04 g/cm, decomposition temperature is 280-300℃.
Poly(dimethyldiallylammonium chloride) contains a strong cationic radical group and an active adsorbent radical group, which destroys and flocculates suspended and negatively ionized water-soluble substances in wastewater through electro-neutralization and bridging adsorption. Poly(dimethyldiallyl ammonium chloride) is very effective in flocculation, decolorization, Algaecide and removal of organic matter with low dosage, flocculation hit, fast sedimentation and low turbidity residue. Dimethyldiallylammonium chloride can be used in pH 0.5-1.4, is odorless and harmless.
Poly(diallyldimethylammonium chloride)(PDADMAC) is a kind of Water Treatment Agent with good performance, which has been widely used in sewage treatment and sludge dewatering treatment.
Poly(diallyldimethylammonium chloride) (PDADMAC) has the advantages of high positive charge density, good water solubility, high efficiency, low cost and so on, it is a kind of Flocculant and coagulant with good performance, which is mainly used for solid-liquid separation process in industry. Its compounding with polyaluminum chloride can complement each other's advantages, making the flocculation effect better, the treatment cost lower, and the operation and post-treatment easier.
