polyacrylamide

Polyacrylamide (abbreviated as PAM) is a linear high-molecular polymer with the chemical formula $(C_{3} H_{5} NO)_{n}$ . It is classified into non-ionic, anionic, cationic and amphoteric ionic types based on ionic properties, with significantly different uses for each type.

Core Application Fields

Water Treatment: Its most important application. Anionic PAM is used for flocculation and sedimentation in industrial wastewater (e.g., steel and printing-dyeing wastewater), while cationic PAM is applied in municipal sewage treatment and sludge dewatering to accelerate solid-liquid separation.
Oil Exploitation: Used as a drilling fluid additive to reduce fluid loss, or as an oil displacement agent to improve crude oil recovery efficiency.
Paper Industry: Serves as a retention aid and strength agent to enhance paper strength and fiber retention rate, reducing raw material waste.

Key Characteristics

Good water solubility, easy to form high-viscosity solutions, and strong flocculation effect;
Low dosage, high efficiency, and little secondary environmental pollution (for compliant products);
The corresponding ionic type must be selected according to water quality and working conditions to achieve the best effect.
