Hydrolyzed Polyacrylonitrile sodium salt Na-HPAN
Na-HPAN,Filtration reducer
water-based drilling fluid
Introduction
Na-HPAN is copolymer of several polymers such as acrylamide and sodium acrylate acrylonitrile.
Na-HPAN, hydrolysis product of polyacrylonitrile add sodium hydroxide, is yellowish powder, soluble in water, and its solution is alkalescent, used for water-based drilling fluid loss with some role of viscosifier; In freshwater drilling fluid system, anti-scar can reach 250°C and is stable.
