水解聚马来酸酐HMPA
【CAS】 26099-09-02
中文：水解聚马来酸酐
【CAS】 26099-09-02 别名：聚马来酸 Dequest：P9000
结构式：
一、产品性能：
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。 HPMA适用于
碱性水质或同其它药物复配使用。HPMA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HPMA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HPMA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。
二、质量指标 符合GB /T 10535-1997

三、使用方法：
HPMA通常以1~15ppm与有机磷酸盐复合，用于循环冷却水、油田注水、原油脱水处理及低压锅
炉的炉内处理，具有良好的抑制水垢生成和剥离老垢的作用，阻垢率可达98%。HPMA与锌盐复配时，能
有效地防止碳钢的腐蚀。
四、安全与防护：

HPMA为酸性，应避免与皮肤、眼睛等接触，接触后应用大量水冲洗。
五、包装与储存：
HPMA为塑料桶包装，每桶25kg或由用户确定。贮存期为十个月。
英文：Hydrolyzed Polymaleic Anhydride
CAS: 26099-09-02
Structure:
o
1,Properties: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 330C.
HPMA has obvious threshold effect under high temperature (350C) 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 300C 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.

3,Using method:HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for
circulating cool water system, oilfield fill water, crude oil dewatering and low-pressure boilers. HPMA has
good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can
effectively inhibit carbon steel corrosion.
4,Safety Protection:Acidity, Avoid contact with eye and skin, once contacted, flush with water.
5,Package and Storage:Normally In 25kg net Plastic Drum, or packing as customers' required. Storage
for ten month in room shady and dry place.
