1、 产品性能Product performance

本品是有机脂肪酸聚合物，为一种低分子量电解质，含有多个羧基官能团，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^。C以上。在高温和高PH下有明显的溶限效应。该剂具有与有机瞵酸、有机瞵磺酸、PBTC等更好的混溶性，适用于碱性水质或同其它药物复配使用。在300^。C下对碳酸盐和磷酸盐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, polymer of organic aliphatic acid, is a low molecular-weight electrolyte, containing several carboxyl groups, 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 and high pH level. I t has good compatibility with organic phosphoric acid , organic sulfonic acid and PBTC, 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.

2、用途 Usage

适应于电力、化工、冶金行业循环冷却水、油田注水、原油污水、低锅炉阻垢、防垢处理，适应于碱性水质或其它水稳剂复配使用。

Applicable to anti-scale and scale inhibitions in circulating cool water, oilfield feed water, crude oil wastewater, and low pressure boiler in power plant, chemical industry and metallurgy industry. It is adapt to alkaline water or built with other agents.
