Introduction of Anionic Polyacrylamide
Anionic polyacrylamide, abbreviated as APAM, is a derivative product of polyacrylamide (PAM) and its electric charge is electronegative which consists of functional groups such as sulfonic acid, phosphoric acid or carboxylic acid.
Industry Overview of Anionic Polyacrylamide
Polyacrylamide market share was valued at $3.9 billion in 2018 and is expected to exhibit 9% CAGR (Compound Annual Growth Rate) throughout the forecast timespan.
Industry related products across various industries such as wastewater treatment, petroleum, transportation, electric power, and papermaking are widely used and will dominate the industry growth over the forecast period.
The product segment of the polyacrylamide market is separated into NPAM (Non-ionic), CPAM (Cationic), APAM (Anionic), and others. In 2018, APAM accounted for more than 50% of the peak share due to its use in paper manufacturing, wastewater treatment and oil recovery businesses.
Applications of Anionic Polyacrylamide
1) Drinking water treatment
Many water in China’s water plants comes from the river water, which contains large sum of sediment and mineral, it still cannot meet the requirements even after precipitation and filtration, so the flocculant is needed. With using PAM flocculants, 1/50 additive amount that of inorganic flocculants, it will be several times and even dozens of times more effective than the inorganic flocculants.
2) Displacement agent for tertiary recovery of oilfield
It can adjust the water injection rheology, increase the viscosity of the replacement fluid, improve the efficiency of the replacement fluid spread, so that the water permeability of the formation decreased and the water and oil are maintained at at constant speed.
3) Papermaking additives
It can be used as the retention agent, the filter agent, and the reinforcing agent for the wet and dry paper in papermaking industry.
4) Drilling mud material
It is used as drilling mud additive in oil field exploration and development and geological, water conservancy and coal exploration.
5) It can be used to improve water quality, air quality and soil surface infiltration rate, minimize soil crusting to allow for uniform plant growth.
Features of Anionic Polyacrylamide
APAMs are characterized by high degree of polymerization and high molecular weight, and it possesses various properties such as flocculation, thickening, shear, drag reduction and dispersion. In addition, APAM is cost effective, which mainly drives its widespread use in the industry. Thus, it is mainly used in petroleum recovery, mineral processing, metallurgy, chemicals, paper, textiles and food processing.
