Properties：
PAPEMP is the latest generation of water treatment agent, featuring high chelating and dispersing performance, high calcium tolerance, and excellent scale inhibition properties. This agent can be used as a scale and corrosion inhibitor in circulating cooling water systems, and is particularly suitable for circulating cooling water systems with high hardness, high alkalinity, and high pH, as well as oilfield water treatment. It has excellent scale inhibition performance against calcium carbonate, calcium phosphate, and calcium sulfate. Meanwhile, it can effectively inhibit the formation of silica scale and has a good effect on stabilizing metal ions such as zinc, manganese, and iron.
Applications：
PAPEMP is used as a membrane scale inhibitor in reverse osmosis systems, and as a scale and corrosion inhibitor in systems with high salt content, high turbidity and high temperature such as multi-stage flash evaporation systems (e.g., scale inhibition in high-temperature and high-turbidity water systems of coal gasification systems); it is also used as an auxiliary agent in textile printing and dyeing and papermaking (as a yellowing inhibitor); and it can replace EDTA, DTPA, NTA, etc.
