水膨胀材料（WSM）是通过使用合成树脂弹性体作为基础材料将高吸收性聚合物、填料和溶剂共混而获得的流体密封剂。在本研究中，我们实验研究了WSM的组成，膨胀的程度，WSM的强度和膨胀材料作为垃圾填埋场的联合截水处理材料的长期性能。结果之一是，调节作为WSM组分的高吸收性聚合物的醚化程度和合成弹性体的树脂含量有助于改善密封剂的溶胀和溶胀材料的强度。此外，在长期试验中，WSM的强度趋于稳定，并且证实其具有足够的耐压性，可用于正在考虑将其用作截水处理材料的沿海垃圾填埋场。
Water-swelling material (WSM) is a fluid sealant obtained by blending high-absorbency polymer, a filler, and a solvent by using a synthetic resin elastomer as the base material. In this research, we studied experimentally the composition of WSM, the extent of swelling, the strength of the WSM and the long-term performance of the swelling material used as a jointed water cutoff treatment material at waste landfill sites. One of the results was that adjusting the degree of etherification of the high-absorbency polymer, which is a component of the WSM, and the resin content of the synthetic elastomer contributed to improvement of the swelling of the sealant and the strength of the swelling material. Further, in long-term tests, the strength of the WSM tended to become stabilized and it was confirmed that it had sufficient pressure resistance for use in coastal landfill sites, where its application as a water cutoff treatment material is being considered.
