Polyquaternium-7 CAS 26590-05-6

Introduction

The product is a colorless to light yellow liquid with a specific gravity of about 1.02g/cm3 and a decomposition temperature of 150℃. It is easily soluble in water and has good stability. This product is a copolymer of cationic monomer dimethyldiallylammonium chloride and non-ionic monomer acrylamide. It is cationic and has a high molecular weight. It has electrical neutralization and strong adsorption and bridging effects. Therefore, it is mainly used as a flocculant in solid-liquid separation processes.

Specification

Application

This product is used as a flocculant for sludge regulation in urban sewage, industrial sewage and wastewater treatment systems. It is particularly suitable for dehydration of organic sludge suspensions and biodegradable sludge such as raw sewage or processed sewage, food processing wastewater, fermentation wastewater, and various types of industrial wastewater clarification treatment. This product can be used as a retention agent in the papermaking industry, as well as for dehydration of fiber-containing wastewater sludge. Treat various mineral sludges during mining and mineral processing. It can also be used for oil-water separation, crude oil dehydration and oily sewage treatment in oil fields and refineries. Usage:

Before dosing, conduct a beaker test to determine the method of use and the best dosage. When used, it should be prepared into a 0.1-1% water bath solution. Reference dosage: The dosage in sludge dehydration is 0.2% of the total sludge solids, depending on the nature of the sludge; when treating mineral sludge, it is generally 0.1-25mg/kg (ppm) of the sludge weight. 

Packaging and storage

Use PE plastic barrels of 125kg and 200kg.

Sealed packaging, sealed storage, avoid contact with strong oxidants. Valid for two years, can be transported as non-dangerous goods.
