摘　　要：将氨基三甲叉膦酸(ATMP)和羟基乙叉二膦酸(HEDP)进行复配,研究其缓蚀阻垢性能。结果表明,当AT-MP∶HEDP为3∶2时,缓蚀率最大,为95.61%;当Ca2+浓度为250 mg/L时,缓蚀率最大,为92.03%;当ATMP∶HEDP为2∶3时,阻垢率最大为93.46%;当Ca2+浓度在50～150 mg/L时,阻垢率达到90%以上。电极化曲线表明,ATMP和HEDP复配后属于混合型缓蚀剂。缓蚀效果更好,腐蚀产物膜更平整,结构更致密,从而更好地隔离了K55钢与腐蚀介质的接触,进而起到保护钢的作用。ATMP and HEDP complex, corrosion and scale performance were studied. The result showed that when ATMP： HEDP is 3 ： 2, corrosion rate up to 95. 61% ; when the concentration of Ca2＋ is 250 mg/L,corrosion rate up to 92. 03% ; when ATMP ： HEDP is 2 ： 3, scale inhibition rate up to 93.46% ,when Ca2＋ concentration is in the 50- 150 mg/L,inhibition rate reached more than 90%. The electrode curve showed that ATMP and HEDP compound are mixed type inhibitors. Inhibition effect is better, corrosion product film is more smooth, the structure is more dense,in order to isolate the K55 steel with corrosive media contact betterly, and then played the role in the protection of steel.
