摘要
本文用Ensulin法和Tl法研究了磁处理对粘土膨胀的影响,证实了磁处理对粘土膨胀的抑制作用,其中包括磁处理对粘土在水中和阴离子、非离子活性剂水溶液中膨胀的抑制作用和对无机盐、阳离子活性剂、无机和有机阳离子聚合物等防膨剂的增效作用。研究表明,不同的磁感应强度对粘土防膨效果有不同的影响,不同体系有不同的最佳磁感应强度,但一般在60～200mT的范围。
The effect of magnetic treatment on clay swelling has been studied with Ensulin method and TI method. The inhibition of magnetic treatment on clay swelling in water and surfactant solutions and the synergism of magnetic treatment for different kinds of anti-swelling agents, such as salts, cationic surfactant, inorganic and organic cationic polymers were confirmed. The effects of various magnetic induction strength on clay swelling are different. The optimum magnetic induction strengths for different systems are in the range of 60-200mT.
