Cationic Polyacrylamide (CPAM)

Category:

CAS No.:

9003-05-8

Molecular Formula:

(C3H5NO)n

Structural Formula:

PAM

Properties:

Cationic polyacrylamide (CPAM) is a type of polyacrylamide that has positively charged functional groups on its molecular chains. Cationic polyacrylamide (CPAM) is highly soluble in water and can form clear solutions at low concentrations.Due to the positively charged functional groups, Cationic polyacrylamide (CPAM) can attract and bond with negatively charged particles and suspended solids in water, leading to flocculation and sedimentation. This property makes Cationic polyacrylamide (CPAM) useful in the treatment of wastewater and industrial effluents.

Usage:

Cationic polyacrylamide (CPAM) is a type of polyacrylamide that has positively charged functional groups on its molecular chains. It is widely used in various industries for its unique properties. Some of the common usages of cationic polyacrylamide are:

Water Treatment: Cationic polyacrylamide (CPAM) is used as a coagulant to remove suspended solids, organic matter, and heavy metals from industrial wastewater and municipal sewage. CPAM can bind to negatively charged particles and form flocs that can be easily separated by sedimentation or filtration. It is also used as a flocculant in drinking water treatment to remove turbidity and impurities.

Papermaking: Cationic polyacrylamide (CPAM) is used as a retention and drainage aid to improve paper strength and reduce fiber loss. CPAM can adsorb onto the surface of fibers and fillers, increasing their affinity for water and improving their retention in the paper sheet. It can also improve drainage by enhancing the formation and settling of fiber flocs.

Textile industry: Cationic polyacrylamide (CPAM) is used as a sizing agent and finishing agent to improve the stiffness, strength, and crease resistance of fabrics. CPAM can form a thin film on the surface of fibers, increasing their adhesion and improving their mechanical properties. It can also reduce the formation of wrinkles and shrinkage during washing and ironing.
Oil and gas industry: Cationic polyacrylamide (CPAM) is used in the enhanced oil recovery process to increase the viscosity of injected water and improve the displacement efficiency of oil. CPAM can reduce the mobility of water and improve the sweep efficiency of oil, leading to increased recovery rates and reduced production costs.

Ⅱ, III reservoir resources formation temperature is in the 70-95 °C, while formation salinity is in the 10000-30000 mg/L with 800 mg/L of divalent ions .With the use of regular polyacrylamide under these conditions, there will be serious thermal degradation, the degree of hydrolysis increasing, the case of multi-charged ions combined with precipitation and other issues, the effect of variation of the tackifier. Our polyacrylamide for Temperature and salt resistance in this class reservoir conditions can meet the requirements of viscosity, temperature, salinity and shear performance of flooding.

Mining industry: Cationic polyacrylamide (CPAM) is used as a flocculant to settle and dewater mineral tailings, reducing the environmental impact of mining activities. CPAM can improve the settling rate and compaction of tailings, leading to reduced water consumption and improved tailings storage capacity.

Agriculture: Cationic polyacrylamide (CPAM) is used as a soil conditioner and water retention agent to improve soil structure, increase water retention, and reduce soil erosion. CPAM can bind to soil particles and improve soil aggregation, leading to increased porosity and water holding capacity. It can also reduce surface runoff and soil erosion by improving soil stability and reducing soil surface sealing.
