Properties:
PASP is a water-solublepolymer, a new type of green water treatment agent with characteristics ofphosphorus free, non-toxic, pollution-free, and completely biodegradable. Ithas strong chelating ability towards ions and dual effects of corrosioninhibition and scale inhibition. It has good scale inhibition effect on scalingsalts such as calcium carbonate, calcium sulfate, barium sulfate, and calciumphosphate, with a scale inhibition rate of up to 100% for calcium carbonate.PASP also has a dispersing effect and can effectively prevent corrosion ofmetal equipment.
PASP can replace phosphoruscontaining water treatment agents to avoid eutrophication of water bodies andsecondary pollution discharge.

Usage:
PASP, as a scale and corrosion inhibitor,is widely used in industrial circulating water, boiler water, reverse osmosis water,oilfield water, seawater desalination and other water treatment fields. Itperforms excellently in high hardness, high alkalinity, high pH, and highconcentration systems, and its scale inhibition effect is superior to commonlyused phosphine containing scale inhibitors. The combination of PASP and PBTCAhas a synergistic effect.
Dueto its green and environmentally friendly characteristics, PASP products can beused as new daily chemical additives and various non-toxic and pollution-freespecialized fine chemicals.
PASPcan be used as a nutrient absorption enhancer in agriculture, promoting theproduction of vegetables, fruits, flowers and other crops. At the same time,when used in combination with pesticides, it can improve its efficacy.
The binary system composed of PASP, HEDP,and Zn2+has a synergistic corrosion inhibition effect on carbon steel. Thecombination of PASP and HEDP can form a low phosphorus formula. For example,when the drug composition is PASP (18mg/L), HEDP (4mg/L), or Zn2+(2mg/L), thephosphorus content is less than 1.2mg/L, the corrosion rate is less than0.05mm/a, and the corrosion inhibition performance is excellent, making it alow phosphorus water treatment formula.
