Factory Direct Selling Polyacrylamide PAM for Oilfield Wastewater Treatment Drilling Fluid Papermaking
Polyacrylamide is a linear water-soluble polymer, and is one of the most widely used varieties of water-soluble polymer compounds. PAM and its derivatives can be used as efficient flocculants, thickeners, paper enhancers and liquid drag reducing agents, and Polyacrylamide are widely used in water treatment, paper making, petroleum, coal, mining, metallurgy, geology, textile, construction and other industrial sectors.
The polyacrylamide is water -solution high polymer with good flocculanting activity can reduce the friction resistanca between liquid.
1.Flocculation: PAM can make the suspended material through electrical neutralization, play the role of flocculation.
2.Adhesiveness: The impurities can be bonded together to precipitate to the bottom.
3.Thickening Agent: In neutralizing acidic conditions have thickening effect, if the PH value is more than 10 PAM easy hydrolysis.
Polyacrylamide(PAM) include anion (APAM), cation (CPAM), non-ionic (NPAM) and zwitterion (ACPAM). Polyacrylamide is mainly used in coal washing plant,printing and dyeing factory,farm,sewage treatment plant,oil field,concentrating mill,etc.
Anion Polyacrylamide (APAM) is one of the most widely used water-soluble polymers. Anionic polyacrylamide (APAM) include: ultra high molecular weight(over 25 million), high molecular weight(up to 20 million), medium molecular weight(about 16 million), Solid content over 89% .
Nonionic Polyacrylamide (NPAM) include: medium molecular weight(over 15 million), low molecular weight(up to 8 million), Solid content over 89%.
Cation Polyacrylamide (CPAM) is a type of polyacrylamide that has a positively charged functional group, such as amino or quaternary ammonium, which makes it highly effective in binding with negatively charged particles, such as clay, silt, and organic matter in water.
Amphoteric polyacrylamide(ACPAM) , due to its molecular inclusion of cationic and anionic groups, exhibits superior performance in addition to the characteristics of general cationic flocculants. This type of flocculant can be used within a wide range of pH values, with higher filtration capacity and lower cake moisture content. It can also be used for strong acid leaching of ores or for recovering valuable metals from acidic catalysts containing metals.

Flocculation Experiment ：
Application areas :
Sewage treatment:
City sewage treatment, food processing, metallurgy, dyeing industry, mineral processing industry, sugar industry and various kinds of industrial wastewater treatment.
According to the properties of suspended matter, concentration and flocculation performance of polyacrylamide, precipitation can be divided into: natural precipitation, flocculation precipitation, regional precipitation. The concentration of suspended particles in regional precipitation is higher (more than 5000mg/L), and the settlement of particles is affected by other surrounding particles, and the relative positions of particles remain unchanged, forming a whole common sinking, and there is a clear mud-water interface between them and the clarified water. Regional sedimentation occurred in both secondary sedimentation tank and sludge thickening tank.
Paper industry:
Paper industry can be use for paper dry strength agent, retention agent, filter aid,improving paper quality and paper production capacity.
APAM is also used in the papermaking process .The main application of polyacrylamide in the paper industry has two aspects: one is to improve the retention rate of additives, pigments, etc., in order to reduce the loss of raw materials and environmental pollution; The second is to improve the strength of the paper.
Due to the different purpose of PAM used in the paper industry, the requirements for the relative molecular weight and carboxyl group content (degree of hydrolysis) of the polymer are also different. So the APAM have a widely use in papermaking process.
Oil industry:
Polyacrylamide is widely used in oilfield chemicals such as clay anti-expansion agents, thickeners for oil field acidification, and oily wastewater treatment agents.
In general, PAM is more commonly used in the oil field due to its effectiveness as a flocculant and its ability to improve the rheological properties of drilling fluids. However, CPAM can also be effective in certain applications and may be preferred in some cases. The choice of which type of polyacrylamide to use depends on the specific needs and conditions of the oil field operation.
