Partially Hydrolyzed Polyacrylamide PHPA
1. Property
PHPA is a partially hydrolysed co-polymer of acrylamide of high molecular weight. It is used in low solids and clear water drilling fluids.
2. Use
● PHPA is effective in fresh and salt water drilling fluids, minimizing the build up of solids in drilling fluids.
● Also it is effectively prevents clay and shale problem such as welling, sloughing, bit balling and mud rings.
● Prevents dispersion and swelling shales and clays by way of encapsulation.
● Promotes more effective removal of solids at the rig shale shaker, thereby minimizing drilled solids build up.
● Promotes rapid settling of cuttings in settling pits.
3. Packing
25KG or 50LB net sealed in 4-in-1 compound paper bag with plastic lining during storage and transport see that the bag is intact.
