Product Features
- PASP is a water-soluble polymer,, a new type of green water treatment agent, which is phosphorus-free, non-toxic, pollution-free and fully biodegradable.
- PASP has a strong chelating ability to ions, has the dual effect of corrosion inhibition and scale inhibition, has a good scale inhibition effect on calcium carbonate and other scale salts, and the scale inhibition rate of calcium carbonate can reach ≥95%. At the same time, it has a dispersive effect and can effectively prevent the corrosion of metal equipment.
- PASP can replace water treatment agents containing phosphorus to avoid eutrophication and secondary pollution.
Applications & Usage
- PASP is widely used in industrial circulating water, boiler water, reverse osmosis water, oilfield water and other water treatment fields as a scale inhibitor and corrosion inhibitor.
- PASP has excellent performance in high hardness, high alkalinity, high pH and high concentration ratio systems, and its scale inhibition effect is better than that of common phosphate-containing scale inhibitors. The combination of PASP and PBTCA has synergistic effect.
- Because of the characteristics of green environmental protection, PASP can be used as a new type of daily chemical additives and a variety of non-toxic, pollution-free special fine chemicals.
- In agriculture, PASP can be used as a nutrient absorption enhancer to promote the production of vegetables, melons, fruits, flowers and other crops, and at the same time, it can improve the efficacy of pesticides.
