As the increase in the concentration of trichloroisocyanuric acid,CaCO3 scale inhibition efficiency of HEDP,PBTCA and HPAA increases firstly but decreases afterward,and CaCO3 scale inhibition efficiency of PAPEMP decreases continuously.

• 随着水中三氯异氰尿酸浓度的增加,HEDP、PBTCA和HPAA的阻CaCO3垢率先增加而后降低,PAPEMP的阻CaCO3垢率则持续降低。
