吸水膨胀材料是以合成树脂弹性体为基料，加入高吸水性聚合物、填料和溶剂而成的橡胶状防渗材料。通过室内膨胀率试验，研究了膨胀材料作为滨海垃圾填埋场防渗材料对COD和BOD污染水体的膨胀特性。通过对膨胀压力的测定，明确了影响吸水膨胀材料膨胀压力的因素。结果表明，浸泡水中的COD和BOD浓度都会影响遇水膨胀材料的膨胀率。当水膨胀材料的厚度为2mm和3mm时，具有0.5MPa或更大的最大膨胀压力，其对应于50m深度的液压。
A water-swelling material is one of the rubbery impermeable materials which mixed synthetic resin elastomers as a base material, high absorbency polymers, filler and solvents. In this study, swelling characteristics of the water-swelling material on the water polluted with COD and BOD, as an impermeable material at coastal landfill sites, are examined by laboratory swelling ratio test. Furthermore, the factor in which it influences the swelling pressure of water-swelling material is clarified by measuring the swelling pressure. As the results, the COD nor the BOD concentrations in the soaked water influence the swelling ratio of the water-swelling material. When the thicknesses of water-swelling material are 2 mm and 3 mm, the maximum swelling pressure of 0.5 MPa or more that corresponds to hydraulic pressure by depth of 50 m is possessed.
