Polyacrylamide Uses
Polyacrylamide for Edge-water Encroachment Use(PAM As Oil-displacing Agent) When the oil field is exploited in the petroleum tertiary recovery, if the single injection drive is applied, its fluidity is higher than the crude move, as a result, it lowers the spread efficiency and increases the water consumption, and the water content of the crude
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
Polyacrylamide in Oilfield - Sinofloc Chemical
Polyacrylamide is a versatile chemical treatment agent in oilfield. In oil extraction it could be used as a flooding agent, water shutoff regulator, drilling fluid regulator, fracturing fluid additives, especially in cementing, completion and workover. The oil industry is the largest area of polyacrylamide applications.

Polyacrylamide Pam Petroleum Ether Price - Buy Pam
Product name: Polyacrylamide ( PAM ) CAS No.: 9003-05-8 HS Code: 3906901000 Appearance: White granule Package: 25kg / bag, kraft paper bag or as requested Our Polyacrylamide has passed ISO9001: 2008 Quality System Certification. Polyacrylamide is, simply called PAM, a water- soluble high flocculant polymer and widely used in petroleum, paper-making, metallurgical, textile and environment
Thus, PAM is commonly used as a flocculant to improve sedimentation in sewage treatment , oil recovery , paper manufacturing , mining, and other fields [5,6,7]. China is the world’s largest consumer of PAM. Nearly 330,000 t of PAM was consumed in 2008, which was approximately 38% of the world's total consumption.
Biodegradation of Partially Hydrolyzed Polyacrylamide HPAM
Bao, M., Chen, Q., Li, Y., and Jiang, G. 2010. Biodegradation of partially hydrolyzed polyacrylamide by bacteria isolated from production water after polymer flooding in an oil field. Journal of Hazardous Materials 184(1–3): 105–110.
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.
Anion Polyacrylamide(APAM) - GreenPharmChem
Anion Polyacrylamide is a water-soluble linear high molecule polymer with high degree of polymerization; soluble in water, almost insoluble in benzene, ether, lipids, acetone and other organic solvents. With the functions as flocculation, thickening, shear resistance, lower resistive and dispersion performance, it is

Synthesis and characterization of Interpenetrating polymer
Polyacrylamide has been used in contact lenses for a long time and it has well been evaluated as a sustained release wound dressing material (Kulkarni have been prepared by emulsion crosslinking et al., 2000). Fernandez et al. have evaluated the properties of glucose oxidase loaded polyacrylamide hydrogels to be used as
13 polyacrylamide have been widely used for this for carboxymethyl cellulose (CMC), which is ether in as oil-field-drilling mud additives with respect to shale fibers to chemicals by
- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- What are the different types of anionic polyacrylamide synthesis technologies?
- The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
- Is anionic Polyacrylamide a Tier 1 chemical?
