Applications of Poly Dimethyl Diallyl Ammonium Chloride (PolyDADMAC/PDADMAC)

Applications of Poly Dimethyl Diallyl Ammonium Chloride (PolyDADMAC/PDADMAC)

PolyDADMAC/PDADMAC is a water-soluble, non-toxic, low-viscosity, slightly adsorptive white-yellowish, odorless liquid soluble in water. This compound is present in nature or extracted from natural sources but is also produced synthetically in labs.

It can be used in various industrial applications, including drinking water disinfection and wastewater treatment, and here we will explain a few of its uses in detail!

1. Wastewater Treatment

PDADMAC can be used for wastewater treatment, which is a process that purifies wastewater. Wastewater is any liquid that has passed through the septic tank or other treatment facilities. It can also be called "sewerage" or "sanitary sewage."

Wastewater usually contains many different chemicals and dissolved materials. The common contaminants are oil from car engines and grease from kitchen appliances, bacteria, viruses, heavy metals such as lead and mercury, industrial waste from factories or agricultural processing plants (including animal faces),  chemical solutions used in industry, laundry detergent powders, etc.

These substances cause problems when they pollute rivers or lakes because they affect fish populations negatively due to their effects on reproduction rates, among other factors like toxicity levels depending on what washes off into these bodies of water.

2. Drinking Water Disinfection

PDADMAC kills bacteria, viruses, and protozoa in drinking water. This compound targets the organism's membrane and kills bacteria such as E. coli O157:H7 and Salmonella Typhimurium and viruses like HAV. These are the common microbes and major problems in drinking water resources.

3. Pulp and Paper Industry

Poly DADMAC is widely used as a flocculant in the pulp and paper industry, where it removes fine particles from paper pulp, which makes it essential for many types of printing papers. In addition, it has also been shown that pdadmac may be used to remove fine particles from water.

4. Flotation Separation of Cationic Polyacrylamide and Ferric Salts

PDADMAC is a cationic polymer that has been applied as a flocculant, softener, and suspending agent in the pulp industry, where it isolates cationic polyacrylamide from ferric salts.

It can also be used in printing processes, such as offset and flexographic printing, by providing good adhesion, surface hardness, and gloss to offset printed boards.

5. Decolorization, Deodorization, and Dyeing of Textiles

PDADMAC is a cationic surfactant used in textile dyeing and finishing. It is also used for the decolorization, deodorization, and dyeing of textiles.

The main use of PDADMAC is as a decolorizer in the textile industry. This product can be applied to any type of fabric or material that requires color removal with minimum structural damage, such as woolen fabrics, silk fabrics, etc.

This compound can work with a flexible pH range, making it easier to work with it than other chemicals. The major benefit of PDADMAC is that only a small amount of compound is enough to get the job done, and that amount is what affects the perfection of your work.

PDADMAC is a colorless, odorless, and tasteless liquid. It has no pungent taste. It is used as a solvent in manufacturing other chemicals or as a blowing agent in plastics, films, and other applications where it acts as a plasticizer to improve sealing properties.
