More Information
Summary:The invention relates to the technical field of scale inhibitors, and particularly discloses a formula and a preparation method of a reverse osmosis membrane scale inhibitor. The reverse osmosis membrane scale inhibitor comprises 20 to 30 parts of polyaspartic acid, 20 to 30 parts of tannin, 10 to 20 parts of alkyl epoxy carboxylate, 8 to 12 parts of a non-oxidation bactericide and 100 parts of deionized water, wherein the polyaspartic acid is sulfonic modified polyaspartic acid. According to the preparation method, the adding sequence of all the components and the pH value of the scale inhibitor are optimized, effective and uniform dispersion of all the components is ensured, and the stability of all the components is improved. The reverse osmosis membrane scale inhibitor provided by the invention has the characteristics of good scale inhibition effect, strong hard water resistance, greenness and no pollution. 本申请涉及阻垢剂技术领域，具体公开了一种反渗透膜阻垢剂的配方及其制备方法。一种反渗透膜阻垢剂包括聚天冬氨酸20-30份、单宁20-30份、烷基环氧羧酸盐10-20份、非氧化杀菌剂8-12份、去离子水
