Modified cross-linked polyacrylate

主要用途 土木工程防水剂、电缆防水剂等 基本信息 改性聚丙烯酸交联物是主要用于土木工程的耐盐吸水树脂。即使用于海水等含有大量电解质的水，也能保持稳定的吸水率。 优点特性 对地下水和海水的吸收卓越 一般的吸水性树脂在遇到海水等盐分浓度高的水溶液或者多价金属盐水溶液时，吸收能力就会下降，但 改性聚丙烯酸交联物能够保持吸收能力。 吸收特性概要 ※3：0.9%氯化钠水溶液 ※4：含一价至二价离子的电导率为43.0-48.0mS/cm的水溶液 ※5：5%氯化钙水溶液 Main Applications Water blocking agents for civil engineering and cables, etc. Basic Information Modified cross-linked polyacrylate are salt-tolerant and water-absorbing polymers that are mainly used in civil engineering. These polymers maintain a stable water absorption amount, even in seawater and other such water containing large quantities of electrolytes. Features and Properties Excellent absorption of groundwater and seawater The amount of water absorbed by general water-absorbing polymers decreases in seawater and other such aqueous solutions with a high saline concentration and in polyvalent metal salt aqueous solutions; however, Modified cross-linked polyacrylate polymers maintain their water-absorption amounts in such aqueous solutions. Overview of Absorption Properties *3: 0.9% sodium chloride aqueous solution *4: Aqueous solution of 43.0 – 48.0 mS/cm electrical conductivity containing univalent – bivalent ions *5: 5% calcium chloride aqueous solution
