Study on rheology and microstructure of phenolic resin cross-linked nonionic polyacrylamide (NPAM) gel for profile control and water shutoff
In this study, the rheological properties and microstructure of phenolic resin gel were measured by using a Haake Mars 60 rheometer and a Carl Zeiss Jena cryo-etching electron microscope. Viscosity and viscoelastic moduli of the gel rose
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

nonionic polyacrylamide (BNPAM) [ ]. It demonstrated better occulation properties for clay suspension, but did not show good occulation performance for sewage.
Nonionic polyacrylamide exhibits neutral nonionic properties in the aqueous solution which is hardly influenced by the PH value in the application. SINOFLOC nonionic flocculants are suitable for use as a settlement aid in many different mineral-

1. Characteristics of nonionic polyacrylamide Nonionic polyacrylamide is a high polymer with the high molecular weight and the low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film forming, gelating and
Polyacrylamide - an overview | ScienceDirect Topics
7.5.1.1 Properties Polyacrylamide (PAAM) forms soft, cationic nondegradable hydrogels consisting of entangled polymer chains tethered to one another via cross-linkers [175] . Its hydrophilic nature results in a high capacity for swelling and
When used as a drainage aid, polyacrylamide can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes. In addition, these additives improve the drainage of

Polyacrylamide (PAM) is a linear organic polymer, and it is the most widely used flocculant in water treatment chemicals.It can enhance flocculation, reduce the cost of clean water, improve water quality, and remove organic matter and algae in
- Which polymer based enhanced oil recovery (EOR) process uses partially hydrolyzed polyacrylamides?
- Worldwide partially hydrolyzed polyacrylamides (HPAM) are preferentially used for polymer-based enhanced oil recovery (EOR) processes, due to cost-competiveness.
- Is partially hydrolyzed polyacrylamide biodegraded by bacterial strains isolated from Omani oil fields?
- In present study the biodegradation of partially hydrolyzed polyacrylamide (HPAM) by bacterial strains isolated from Omani oil fields was analyzed. HPAMs are extensively used in oil fields for enhanced oil recovery operations.
- Can hydrolyzed polyacrylamide improve oil recovery?
- Partially hydrolyzed polyacrylamide (HPAM) with high-molecular-weight has been widely and increasingly used in oil industries for enhancing oil recovery (Liu et al. 2012 ).
- Can hydrolyzed polyacrylamide be used as a flooding agent?
- Anyone you share the following link with will be able to read this content: The increasing usage of partially hydrolyzed polyacrylamide (HPAM) in oilfields as a flooding agent to enhance oil recovery at so large quantities is an ecological hazard to the subsurface ecosystem due to persistence and inertness.
