Observations on Viscosity Reduction of PHPA Polymer
The tests showed that the PHPA fluids showed a gradual reduction in viscosity over the first days after mixing and that the rate of reduction was slightly dependent on the quality of the mix water.
Observations on Viscosity Reduction of PHPA Polymer Support Fluids. Polymer fluids have been used in foundation drilling for many years and yet no previous studies have been reported which assess their sensitivity to shear such as is induced by pumping equipment.
Observations on viscosity reduction of PHPA polymer
At first sight the sensitivity of PHPA fluids to shear may be perceived as a disadvantage but in fact if shear can be reduced so can on-site energy consumption. A reduction in fluid viscosity was also observed over a standing period between mixing and use, suggesting that a second mechanism may be contributing to the properties change.

- What is the global polyacrylamide market size?
- The global polyacrylamide market size was valued at USD 4.5 billion in 2018 and is projected to expand at a CAGR of 6.2% from 2019 to 2025 . In volume, this represents an output of about 2.5 million tons. Polyacrylamide, or PAM, is made from the acrylamide monomer.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative 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 modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Can polyacrylamide be used as a coagulant aid?
- Reduce the amount of flocculant. Under the premise of achieving the same water quality, the use of polyacrylamide as a coagulant aid in combination with other flocculants can greatly reduce the amount of flocculant used. Improve water quality.
