Abstract:

The performance of the home-prepared novel phosphonic sulfonic acid corrosion and scale inhibitor,called amino sulfonic acid dimethylene phosphonic acid （SADMP）,has been evaluated. The results show that the CaCO₃ scale inhibition efficiency of SADMP is excellent. The Ca₃（PO₄）₂ inhibition efficiency of SADMP is also good,and its scale inhibition rate is nearly 100% when the effective concentration is 10 mg/L. At the same time,the compatibility of SADMP and biocide is good,and SADMP has some corrosion inhibition efficiency.

Key words: phosphonic sulfonic acid, scale and corrosion inhibitor, recirculating cooling water

摘要：

对自行研制的新型膦磺酸缓蚀阻垢剂氨基磺酸二亚甲基膦酸(SADMP)的性能进行了评定。结果表明，SADMP具有优良的阻CaCO₃垢和Ca₃(PO₄)₂垢性能，在有效质量浓度为10 mg/L时，其阻Ca₃(PO₄)₂垢率接近100%。同时试验表明SADMP与常用杀菌剂的配伍性较好，兼具一定的缓蚀性能。
