含磷聚合物水处理剂PPSA的合成

Synthesis of PPSA as a phosphorus-containing polymer water treatment agent

低磷聚合物水处理剂PPSA以PHP、磺化剂、磷化剂为原料合成,含有羧酸基、酰氨基、磺酸基和膦酰基等基团,样品为含固质量分数25%～30%、pH1～5的水溶液。讨论了合成反应温度和时间对PPSA使用性能的影响,合成反应温度和时间分别以104℃和2.5h为宜。PPSA具有阻垢和缓蚀的双重功能。

PPSA, a low-phosphorus polymer water treatment agent, which has carboxy lic acid group, amide group, sulfonic group, is synthesized by materials such as PHP, sulphur and phosphor agent. The samples are a water solution of solid mate rial 25% ~ 30% and pH 1 ~ 5. It is discussed that PPSA′s applied characteris tics is influenced by synthetic temperature and time. The temperature and time ought to be 104 ℃ and 2.5 h. PPSA is a corrosion and scale inhibitors in water treatment.
