The results showed that the efficiency of 2 phosphinic acid tetrane 1 tricarboxylic acid ( PBTCA ) was better than that of the hydroxyl ethylidene bis ( 2 ethylhexyl ) phosphoric acid ( HEDP ) and the polybasic alcohol phosphonate ester ( PC 604 ) .

结果表明，阻垢剂2膦酸 丁烷1三羧酸（PBTCA）明显优于多元醇膦酸酯（ PC604）和羟基乙叉二膦酸（HEDP），HEDP与PBTCA复配 明显 优于 与 PC604 复配。
