以低分子量聚丙烯酸钠（PAAS）为基础,将聚丙烯酸钠、钼酸钠、D-葡萄糖酸钠、苯并三氮唑、六次甲基四胺等物质按一定比例复配成无磷缓蚀阻垢剂配方,采用碳酸钙沉积法评价其阻垢性能,用旋转挂片法和电化学法评价其缓蚀性能。优选出的最佳缓蚀剂配方为：聚丙烯酸钠15mg/L、D-葡萄糖酸钠14mg/L、苯并三氮唑13mg/L、钼酸钠18mg/L、六次甲基四胺14mg/L,其阻垢率为92.63%,缓蚀率为92.78%。该配方具有无磷、无毒、高效、环保等特点,具有重要的经济和利用价值。
Based on the low molecular weight sodium polyacrylate（PAAS）,the corrosion and scale inhibitor with non-phosphorus formula was prepareded by PAAS,sodium molybdate,D-glucose acid sodium,1,2,3-benzotriazole and hexamethylenetetramine in definite proportion.Its anti-scaling performance was evaluated by calcium carbonate deposition method,its corrosion inhibition was evaluated by rotation specimen method and electro chemical method.The best formula is sodium polyacrylate 15 mg/L,D-glucose acid sodium 14 mg/L,1,2,3-benzotriazole 13 mg/L,sodium molybdate 18 mg/L,hexamethylenetetramine 14 mg/L.The scale inhibition efficiency and corrosion inhibition efficiency of the inhibitor were 92.63% and 92.78% respectively.This formula ethibits the characteristics of no phosphorus,non-toxicity,high efficiency and being environmental friendly.There are important economic and use values.
