PESA (聚环氧琥珀酸)

PESA是一种无磷、非氮的“绿色”环保型多元阻垢缓蚀剂。PESA对水中的碳酸钙、硫酸钙、硫酸钡有良好的阻垢分散性能,阻垢效果优于常用有机膦类阻垢剂。PESA与膦酸盐复配具有良好的协同增效作用。同时PESA具有一定的缓蚀作用,是一种多元阻垢剂。PESA生物降解性能好,应用范围广泛,尤其适用于高碱、高硬、高PH条件下的冷却水系统,可实现高浓缩倍数运行。PESA与氯的相溶性好,与其它药剂配伍性好。

PESA中文名:聚环氧琥珀酸

PESA英文名:PolyepoxysuccinicAcid(PESA)

分子式:HO(C4H2O5M2)nH

一、性能与用途

PESA是一种无磷、非氮的“绿色”环保型多元阻垢缓蚀剂。PESA对水中的碳酸钙、硫酸钙、硫酸钡、氟化钙和硅垢有良好的阻垢分散性能,阻垢效果优于常用有机膦类阻垢剂。PESA与膦酸盐复配具有良好的协同增效作用。同时PESA具有一定的缓蚀作用,是一种多元阻垢剂。

PESA生物降解性能好,应用范围广泛,尤其适用于高碱、高硬、高PH条件下的冷却水系统,可实现高浓缩倍数运行。PESA与氯的相溶性好,与其它药剂配伍性好。

二、技术指标符合HG/T3823-2006三、使用方法

1、PESA适用于油田注水、锅炉水处理等领域。

2、PESA适用于钢铁、石化、电力、医药等行业的循环冷却水系统。

3、PESA特别适用于高碱度、高硬度、高PH、高浓缩倍数系统的锅炉水处理、循环冷却水处理、海水淡化、膜分离等领域。

4、PESA适用于洗涤剂行业。pesa

四、包装与贮存

PESA用塑料桶包装,每桶25kg或250kg或根据用户需要确定。PESA贮存室内阴凉处,贮存期十个月。

五、安全防护

PESA为碱性,操作时注意劳动保护,应避免与眼睛、皮肤或衣服接触,接触后应立即用大量清水冲洗。

Polyepoxysuccinic Acid (PESA)

Molecular Formula: HO(C4H2O5M2)n Molecular weight: 400-1500

Properties:

PESA is a multivariate scale and corrosion inhibitor with non-phosphor and non-nitrogen, it has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale, with effects better than that of ordinary organophosphines. When built with organophosphates, the synergism effects are obvious.

PESA has good biodegradation properties, it can be widely used in circulating cool water system in situation of high alkaline, high hardness and high pH value. PESA can be operated under high concentration index. PESA has good synergism with chlorine and other Water Treatment Chemicals.

Specification:

items index

Appearance Colorless or amble transparent liquid

Solid content % 40.0 min
