Sodium polyacrylate SNPH-PAN
Sodium polyacrylate is an acrylic polymer with a characteristically high level of anionic charge and low molecular weight.
Advantages
- Effective both in solutions with minimal solid phase content and in weighted systems.
- Formation of a strong and at the same time thin filtration crust.
Purpose
Designed to reduce the water loss of fresh and mineralized drilling fluids. It has the ability to adsorb on the surface of clay rocks, encapsulating drilled sludge and stabilizing the walls of the well. For achievement of maximum efficiency, it is advisable to use in combination with polyacrylamide SNPH-PM.
The recommended concentration is from 1.5 to 5 kg/m³.
