Polyacrylamide - an overview | ScienceDirect Topics
Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the

Poly-Acrylamide (PAM) - NCSU
POLYACRYLAMIDE. Composition: Though the word "polyacrylamide" is more accurately applied in the case of the homopolymer, papermakers tend to use the term when talking about the most popular varieties of cationic and anionic retention
ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer

Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for

Acrylamide in Drinking-water - WHO
a factor of 2–3. This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of <5 µg/l in both river water and tap water in an area where
Especially, polyacrylamide series are the company's leading products, which can be widely used in water treatment, paper making, textile, petroleum, mineral and other fields. With the selection of cationic monomers and the introduction of
- What is polyacrylamide used for?
- Hence, it is an earth-stabilising fluid that is designed for a variety of applications in the geo-construction industry such as tieback anchors, diaphragm walls, horizontal drilling, tunnelling, slurry trenching, drilled shafts/bored piles, and others. 6.1. Polyacrylamide in drilling technology
- 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 [ , , ].
- What is modified polyacrylamide?
- There are many drawbacks to the use of bentonite, natural polymer, and synthetic polymer. Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity.
- Can hydrophobically modified polyacrylamide gel be used in high temperature drilling?
- Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2025.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.
