水解聚马来酸酐 HPM

 

　HPMA是一种低分子量聚电解质，一般相对分子量为400~800，无毒，易溶于水，化学稳定性及热稳定性高，分解温度在330℃以上。在高温（<350℃）和高PH下有明显的溶限效应。适用于碱性水质或同其它药物复配使用。在300℃以下对碳酸盐仍有良好的阻垢分散效果，阻垢时间可达100h。由于其阻垢性能和耐高温性能优异，因此在海水淡化的闪蒸装置中和低压锅炉、蒸汽机车、原油脱水、输水输油管线及工业循环冷却水中得到广泛使用。另外本剂有一定的缓蚀作用，与锌盐复配效果更好。
HPMA还可用于水泥外加剂。

HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has obvious threshold effect under high temperature (350℃) and high pH（8.3）level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.
