采用鼓泡法评定了α-氨基己二酸-N, N-二甲叉膦酸(AADMP)的阻垢性,研究了 AADMP 药剂的浓度、 Ca2+的浓度、溶液的 pH 值及其温度对其阻垢性的影响,用旋转挂片失重法评定 AADMP 的缓蚀性能.试验研究表明: AADMP 是适用于较高 Ca2+浓度、弱碱性范围、中低温度的阻垢剂.推荐阻垢剂的浓度为25 mg/L 时,阻垢率可达到80%.AADMP 的加入量为30 mg/L 时,对于 A3碳钢和黄铜试片的缓蚀率可达80%以上;与 Zn2+复配, AADMP 的加入量为5 mg/L, Zn2+的浓度为4 mg/L 时,对于 A3碳钢和黄铜试片的缓蚀率在90%左右.因此, AADMP 是一种有效的阻垢缓蚀剂.

The anti -scale of α -aminoadipic acid -N, N′ -dimethylidene -phosphonic acid (AADMP) were assessed by the bubbling method. The effect of scale inhibitor concentration, pH, [Ca2+] , and temperature on AADMP performance were discussed. And the anticorrosion property of AADMP was assessed by a rotary hanged weight losing method. The test results indicated: AADMP is fit for conditions as follows: high rigidity, pH weakly alkaline value, medium low water tempera-ture. Recommended scale inhibitor concentration for 25 mg/L, the scale inhibition rate reached 80%.30 mg/L of AADMP showed well effect of anticorrosion rate for A3 carbon steel and copper anticorrosion rate reach above 80%. Under the running condition of 5 mg/L of AADMP and 4 mg/L of Zn2+, the anticorossion rate of A3 carbon steel and copper were about 90%. So the AADMP is an excellent performance of scale and corrosion inhibitor.
