1、产品性能Product performance
PBTCA对于硫酸盐垢有良好的分散作用,由于它具有膦酸和羧酸的结构特性,使其具有良好的阻垢和缓蚀性能,优于常用的有机膦酸,特别在高温下阻垢性能远优于常用的有机膦酸,能提高锌的溶解度,耐氯的氧化性能好,复配协同性好。
PBTCA has good effect of sulphate scale dispersion. With structural features of both c which enable its excellent scale and corrosion inhibition properties, its anti-scale property, especially under high temperature, is far better than that of organic phosphorus acid. It can improve zinc salt solubility, has good chlorine-resistant oxidation and good compound synergism.

3、用途 Usage
PBTCA在高效阻垢缓蚀剂复配中应用zui广,是性能的产品之一,也是锌盐的优良稳定剂。广泛应用于循环冷却水系统和油田注水系统的缓蚀阻垢,特别适合与锌盐、共聚物复配使用,可用于高温、高硬、高碱及需要高浓缩倍数下运行的场合,PBTCA在洗涤行业中可作螯合剂及金属清洗剂。
PBTCA is most widely used as a high efficient agent of scale and corrosion inhibitor and one of the best performed products. It is also the excellent stabilizer for zinc salt. It is widely used in circulating cooling water system and oilfield refill water system as scale and corrosion inhibitor, especially suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkalinity and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.
4、使用方法 Usage
PBTCA一般与锌盐、共聚物、有机磷、唑类等其它水处理剂复配使用。如单独使用投加剂量为5~15mg/L。
PBTCA is usually used together with zinc salt, copolymer, organic phosphorus, azoles and other water treatment chemicals. When used alone, the dosage of 5-15mg/L is preferred.
