多氨基多醚基甲叉膦酸 (PAPEMP)简介
多氨基多醚基甲叉膦酸 PAPEMP
相对分子质量:约600
结构式
PAPEMP为新一代水处理剂,具有很高的螯合分散性能和很高的钙容忍度及优异的阻垢性能,该药剂可作为循环冷却水系统的阻垢缓蚀剂,特别适用于高硬度、高碱度、高pH的循环冷却水系统和油田水处理。对碳酸钙、磷酸钙、硫酸钙的阻垢性能优异,同时可有效地抑制硅垢的形成,且具有良好的稳定金属离子如锌、锰、铁的作用。
PAPEMP用于反渗透系统的膜阻垢剂,多级闪蒸系统等高含盐量、高浊度、高温系统的阻垢和缓蚀(如煤汽化系统高温高浊水系统的阻垢),纺织印染助剂和造纸助剂(返黄抑制剂),可替代EDTA、DTPA、NTA等。

Properties:
PAPEMP is a new kind of water treatment agent. PAPEMP has high chelation and dispersion effects, high value of calcium tolerance, and good scale inhibition effects. PAPEMP can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system in situations of high hardness, high alkali and high pH value. PAPEMP has excellent scale inhibition ability to calcium carbonate, calcium sulfate and calcium phosphate. PAPEMP can efficiently inhibit the formation of silica scale, stabilize metal ions such as Zn, Mn and Fe.
PAPEMP can be used as scale inhibitor for reverse osmosis system and multistep flash vaporization system in which high salt concentration, high turbidity and high temperature are usually encountered (such as high temperature and high turbidity in coal vaporization system), accessory agent for woven & dyeing (for example, yellow turnback inhibition agent), as alternatives of EDTA, DTPA and NTA .
