Polyamino Polyether Methylene Phosphonae (PAPEMP)
Application
The PAPEMP is especially suitable for high hardness, high alkalinity, or high pH circulating cooling water system and oilfield water treatment. It works excellently in inhibition of calcium carbonate, calcium phosphate and calcium sulphate scales. It is also a good silica scale inhibitor and a good stabilizer of metal ions such as zinc, manganese and iron.
The PAPEMP is adopted by reverse osmosis system, multi-stage flash system, and coal gasification system, which are Valueized by high salinity, high turbidity, and high temperature. The normal dosage is 5-100mg / L. A higher dosage can achieve high concentration treatment. It is also available for compound use with poly-carboxylic acid.
