Phosphino Carboxylic Acid Polymer 膦基羧酸共聚物
Specifications 参数
It has good scale inhibition for barium sulfate, strontium sulfate and silica scale.
对硫酸钡盐，硫酸锶和二氧化硅等具有良好的阻垢性能。
Properties: 性质
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.
通过引入膦集团为羧基,PCA在循环冷却水系统具有良好的分散碳酸钙和磷酸钙的性能。它对硫酸钡、硫酸锶和硅具有良好的阻垢性能。在改善水质、化学稳定性、强氯公差等方面PCA有着广泛的应用。在水循环冷却系统和油田补水系统方面，PCA可用作辅助和抑制剂。
