HPMA和ATMP的缓蚀阻垢性能

INHIBITION AND SCALE PROHIBITING PROPERTY OF HPMA AND ATMP

水解聚马来酸酐（ Ｈ Ｐ Ｍ Ａ）和氨基三甲叉膦酸（ Ａ Ｔ Ｍ Ｐ）的缓蚀和阻垢性能都有最佳浓度值．在相同条件下 Ｈ Ｐ Ｍ Ａ 的缓蚀、阻垢性能优于 Ａ Ｔ Ｍ Ｐ．两种药剂的阻垢率均随 Ｃａ２＋ 浓度的增加而提高，在ｐ Ｈ 为６～９

There was an optimal concentration value of HPMA and STMP respectively for inhibition and scale prohibition. The inhibition and scale prohibtion effect of HPMA was better than that of ATMP in the same concentration . Inhibition and scale prohibition rate of HPMA and ATMP increased considerably with increasing of the Ca 2+ concentration.The scale prohibition rate was relatively stable when PH=6~9.
