water-expandable clay

The preparation of two liquid water swelling polyurethane sealants;

双液型遇水膨胀聚氨酯密封胶的研制

The effects of absorbed dose and a self-made compatibilizer on properties of the radiation vulcanized CR/PAANa water-swellable rubber has been studied.

采用辐射硫化技术制备了氯丁/聚丙烯酸钠遇水膨胀橡胶,考察了在一定辐射剂量时增容剂对膨胀橡胶力学性能、膨胀性能和质量损失率的影响,以及辐射剂量对质量损失率的影响。

After studying the swelling property of CR/PAAS water swellable rubber by radiation cure, it was found that the swelling property was decreased with the increasing of radiation dosage and it was increased with the increasing of PAAS relatively levels.

通过对辐射硫化法制备的遇水膨胀橡胶膨胀性能的研究 ,发现膨胀性能随辐射剂量的增加而下降 ,随 PAAS相对含量的增加而增强 ;在酸、碱、盐水溶液中 ,膨胀性能都显著降低。

Described here is the hydrophilic waterstop, a new type of composite waterproof material, including its effect when used in Chengdu Sewage Treatment Works (Phase Ⅱ), the construction methods and supervision.
