Product description
Polypropylene Imine is a heterocyclic polymer. It is a cationic polymer formed by polymerization of methyl aziridine under certain conditions, also known as dendritic polymer. It contains a large amount of active hydrogen. It can not only chemically react with a variety of functional groups, but also make the suspended substances undergo the processes of electric neutralization, bridging adsorption and flocculation.
Product application area
1. The polypropylene imine has a certain hydrophobicity and can be better separated in the sewage treatment process. And the hydrophilicity can be adjusted by adding hydrophilic substances, so that the method has more selectivity in the application field, and particularly has a better effect in heavy metal sewage treatment.
