The applications of polyacrylamide
For oil extraction applications, polyacrylamide is used to increase the viscosity of water to improve the effectiveness of the water flooding process. polyacrylamide is also widely used in papermaking, potable water treatment, ore processing, and textiles manufacturing.
It can obviously improves the effect of coagulation and expand the application range if the inorganic floccluant be used in concert with the organic polyacrylamide.for high molecular,for the high molecular, the charge on the chain-shaped molecular is greater ,the charge is higher and the chain can be extend fully,the effective range of
Polyacrylamide in Cement Concrete Modification
Polyacrylamide in Cement Concrete Modification. Polyacrylamide can be used to modify the cement concrete in order to improve its flexural strength, its bond strength and its flexural toughness, and its abrasion resistance has a significant effect, it can reduce the crushing ratio, the permeability and the contractility.
2.Applications. √.As flocculants for water treatment. Dosing polyacrylamide can reduce the consumption of coagulant and speed up sedimentation. √.Thickening agent for Textile printing and coating. Added with some other chemicals to prepare chemical grout, is used to starch textiles, can improve the adhesive property, penetrability and desizing performance, enables the textile to have electrostatic prevention performance, reduces the desizing rate.

Polyacrylamide (PAM) and Enhanced Oil - Sinofloc Chemical
For oil extraction applications, polyacrylamide is used to increase the viscosity of water to improve the effectiveness of the water flooding process. A polymer solution is more viscous than brine without polymer. In a flooding application, the increased viscosity will alter the mobility ratio between the injected fluid and the reservoir oil.
In this paper, we study the effects of polyacrylamide (PAM) on both aqueous solutions and fresh cement pastes. Our solution viscosity and hydrodynamic radii measurements in various solutions suggest that calcium ions lead to a cross-linking of anionic PAM and to the formation of PAM micro-gels.
Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
The effect of polyacrylamide (PAA) addition in the ordinary cement and mortar, on the properties, such as setting time, heat of hydration, compressive and tensile strength has been studied by adding 0.5–5.0% additive by weight of cement.
- What is cationic polyacrylamide (CPAM)?
- Cationic polyacrylamides (CPAMs) are widely utilized due to their excellent performance in flocculation and sludge dewatering [ 2 ]. Numerous studies have been conducted on CPAM synthesis technologies, including grafting, free radical polymerization, and polymer modification [ 3 ].
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- What is the difference between cationic starch and cation polyacrylamide?
- The relative efficiency of the cationic starch and cationic polyacrylamide (CPAM) can be attributed to the difference in their charge density (CD). The CD of the C. Starch used in this study is about 0.9 mEq/g and the CD of the CPAM is 2.85 mEq/g. In other words, the CD of the C. Starch is only 31% of CPAM’s CD.
