Research and Evaluation on Water-absorption Swelling Resin LCM
摘要
Abstract
The water-absorption swelling LCM is a kind of effective LCM that is gradually developed in recent years. In this paper, the synthesis conditions of temperature pressure salinity and pH value are evaluated and the experimental results show that the swelling volume increases with higher temperature and pressure, and the pH value and salinity have little effect on swelling capability. Moreover, the active mechanism of this kind of LCM is analyzed based on thermodynamics, equilibrium theory and knowledge of boundary tension.关键词
