Property and Uses
PAPEMP is a new water treatment agent with high chelating properties, high calcium tolerance, and excellent scale inhibition, making it suitable as a scale inhibitor and corrosion inhibitor for circulating cooling water; Polyaminopolyether methylphosphine acid is especially suitable for circulating cooling water systems with high hardness, high alkalinity, and high pH and for oilfield water treatment; It has excellent scale inhibition performance against calcium carbonate, calcium phosphate, and calcium sulfate, effectively prevents the formation of silica scale, and provides good stabilization of metal ions such as zinc, manganese, and iron.
Polyaminopolyether methylphosphonic acid PAPEMP is used as a membrane scale inhibitor in reverse osmosis systems, for scaling and corrosion inhibition in multi-stage flash systems and other high-salinity, high-turbidity, and high-temperature systems (such as scale suppression in coal vaporization systems with high temperature and turbidity water systems), textile printing and dyeing auxiliaries, and papermaking auxiliaries, and can replace EDTA, DTPA, NTA, and others.

How to use
The normal dosage is 5-100mg/L. Unlike other agents, Polyamino Polyether Methylene Phosphonate is more effective the more it doses, the better the effect. It can also be combined with polycarboxylic acids and other ingredients, enabling high concentration ratios.
Packaging and storage
Polyamino Polyether Methylene Phosphonate is typically packaged in plastic drums, with each drum containing 25KG or 200KG; PAPEMP is stored in a cool, shaded indoor area for ten months.
