膦酰基羧酸共聚物

Copolymer of Phosphono and carboxylic Acid (PCA)

别名： POCA

膦酰基羧酸共聚物性能与用途

POCA是在原羧酸基团上引入膦酸基团，对循环冷却水中的碳酸钙、磷酸钙垢有很好的分散性能，并且对硫酸钡和硫酸锶及硅垢的沉积有良好的抑制作用；POCA和其它有机膦酸盐、共聚物复配具有增效作用。POCA具有适用水质范围广、化学稳定性好、耐氯氧化性强等特点。

POCA主要用于工业循环冷却水系统、油田回注水系统的阻垢和缓蚀。

膦酰基羧酸共聚物包装与储存

膦酰基羧酸共聚物用塑料桶包装，每桶25kg或200kg，也可根据用户要求确定；POCA贮于室内阴凉处，贮存期十个月。

Properties:

Through the introduction of phosphonic group into carboxylic group, PCA has good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale. PCA has advantages in wide range of water quality, chemical stability, strong chlorine tolerance, etc. PCA can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.
