摘要:
为改善聚天冬氨酸(PASP)的阻垢性能,对其进行了共聚改性研究。制得了天冬氨酸/谷氨酸的共聚物(PAG)。采用SY/T5673-93方法研究了不同水质条件下PAG对硫酸钙和碳酸钙的阻垢效果,并与商品聚天冬氨酸PASP及含磷阻垢剂(EDTMPS和ATMP)进行对比。结果表明,PAG的阻垢性能与含磷阻垢剂相差不多,PAG明显优于商品PASP的阻垢性能。与商品PASP相比,共聚物更适用于高钙、高温、高pH值以及水力停留时间较长的用水系统。
Abstract:
In order to mi prove the scale-inhibiting performance o f the polyaspart ic acid (PASP), a copo lymer of aspa itic ac id and glutam ic acid ( PAG) is obtained by copolymerizat ion. The sca le-inhibiting propert ies of PAG to calc ium sulphate and calcium carbonate are respectively studied w ith themethod in SY /T5673-93 under different conditions. Morever, the differences of sca le- inhib iting property between PAG, market PASP and the comb inations of phosphorus-containing inh ibitors ( EDTMPS, ATMP) w ere compared. Results show that scale-inh ibiting property of PAG is close to that of the comb inations of phosphorus-contain ing inhib itors, and preferable to that ofmarket PASP. PAG is better than PASP in w ater treatment system w ith high calcium concentration, high temperature, high pH value and long resident tmi e in pipe line.
