| Description & Application | PAPEMP is the latest generation of water treatment agent. It has high chelating and dispersing properties, high calcium tolerance and excellent scale inhibition performance. It can be used as scale and corrosion inhibitor for circulating cooling water system, especially for circulating cooling water system and oilfield water treatment with high hardness, high alkalinity and high pH. It has excellent scale inhibition performance for calcium carbonate, calcium phosphate and calcium sulfate, and can effectively inhibit the formation of silica scale. It also has good stabilization of metal ions such as zinc, manganese and iron. PAPEMP is used as membrane scale inhibitor in reverse osmosis system, scale and corrosion inhibitor in high salt content, high turbidity and high temperature system such as multistage flash system (such as scale inhibitor in high temperature and turbidity water system of coal vaporization system), textile printing and dyeing additives and paper making additives (yellowing inhibitor), which can replace EDTA, DTPA, NTA and so on. |
| Safety Protection | Acidity, avoid contact with eye and skin, once contacted, flush with water. |
