结构式
一、性能与用途：
ATMP具有良好的螯合、低限抑制及晶格畸变作用。可阻止水中成垢盐类形成水垢，特别是碳酸钙垢的形成。ATMP在水中化学性质稳定，不易水解。在水中浓度较高时，有良好的缓蚀效果。
ATMP用于火力发电厂、炼油厂的循环冷却水、油田回注水系统。可以起到减少金属设备或管路腐蚀和结垢的作用。ATMP在纺织印染等行业用作金属离子螯合剂，也可用于金属表面处理剂等。
ATMP固体为结晶性粉末，易溶于水，易吸潮，易于运输和使用，尤其适用于冬季严寒地区。由于纯度较高，可用作纺织印染行业的金属螯合剂及金属表面处理剂。
二、质量指标
三、应用范围与使用方法
ATMP常与其它有机磷酸、聚羧酸或盐等复配成有机碱性水处理剂，用于各种不同水质条件下的循环冷却水系统。用量以1~20mg/L为佳；作缓蚀剂使用时，用量为20~60mg/L。
四、包装与贮存
ATMP液体用塑料桶包装，每桶30kg或250kg；也可根据用户需要确定。贮于室内阴凉通风处，防潮、严防曝晒，贮存期十个月。
五、安全防护
ATMP为酸性，应避免与眼睛、皮肤或衣服接触，一旦溅到身上，应立即用大量水冲洗。

Dequest: 2000
Molecular Formula:
N(CH2PO3H2)3
Molecular weight: 299.05
Structural Formula:
ATMP has excellent chelation, low threshold inhibition and lattice distortion ability. It can prevent scale formation, calcium carbonate in particular, in water system. ATMP has good chemical stability and is hard to be hydrolyzed in water system. At high concentration, it has good corrosion inhibition.
ATMP is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. ATMP can decrease scale formation and inhibit corrosion of metal equipment and pipeline. ATMP can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.
The solid state of ATMP is crystal powder, soluble in water, easily deliquescence, suitable for usage in winter and freezing districts. Because of its high purity, it can be used in woven & dyeing industries and as metal surface treatment agent.
