多元醇磷酸酯 PAPE属于有机膦系列阻垢缓蚀剂
Polyhydric alcohol phosphate ester (PAPE)
结构式：
一、产品性能：多元醇磷酸酯是一种新型的水处理药剂，具有良好的阻垢和缓蚀性能。由于分子中引入了多个聚氧乙烯基，不仅提高了缓蚀性能，也提高了对钙垢的阻垢和泥沙的分散能力。对国内现有阻垢剂所无法控制的水中钡、锶垢沉积有着优良的抑制作用，对水中的碳酸钙、硫酸钙等难溶盐沉积亦有着优良的阻垢作用，对钢材具有阴极保护作用，缓蚀效果优于国内现有的同类产品。多元醇磷酸酯与聚羧酸盐、有机膦酸盐、无机磷酸盐、锌盐等水稳定剂混溶良好。 多元醇磷酸酯用于油田注水采集的阻垢剂（特别推荐作为Nalco Visco 953的代用品），工业冷却水处理的缓蚀阻垢剂。
二、技术指标项 目
指 标
外 观

三、用法用量因水质和工艺条件不同而异。多元醇磷酸酯用作阻垢剂，一般用量小于15mg/L，用作密闭循环缓蚀剂时可高至150mg/L以上。
四、安全防护多元醇磷酸酯为酸性液体，具有一定的腐蚀性，使用时应注意防护。
五、包装与贮存多元醇磷酸酯采用塑料桶包装，每桶净重25kg或200kg。贮存于阴凉干燥处，贮存期十个月。

Polyhydric alcohol phosphate ester (PAPE)
Structural Formula:
Properties :PAPE is a new kind of water treatment chemicals. It has good scale and corrosion inhibition ability. Because more than one ployethylene glycol group is introduced into the molecular, the scale and corrosion inhibition for calcium scale is improved. It has good inhibition effect for barium and strontium scales. PAPE has good scale inhibition effect for calcium carbonate and calcium sulfate, it can mix well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt.
PAPE can be used as scale inhibitor for oilfield (recommended as alternatives of Nalco Visco 953) and industrial cool water system.
