Structural formula:

1. Performance and use:

PASP is a water-soluble polymer and a new type of green water treatment agent. It is phosphorus-free, non-toxic, pollution-free and completely biodegradable. It has a strong chelating ability for ions and has the dual effects of corrosion inhibition and scale inhibition. It has a good scale inhibition effect on scale-forming salts such as calcium carbonate, calcium sulfate, barium sulfate, and calcium phosphate. The scale inhibition rate for calcium carbonate can reach 100%. PASP also has a dispersing effect and can effectively prevent corrosion of metal equipment.

PASP can replace phosphorus-containing water treatment agents to avoid eutrophication of water bodies and secondary pollution of discharge.

3. Usage

1. PASP is widely used as a scale inhibitor and corrosion inhibitor in water treatment fields such as industrial circulating water, boiler water, reverse osmosis water, oilfield water, and seawater desalination. It performs well in high hardness, high alkalinity, high pH, and high concentration multiples systems. The scale inhibition effect of PASP is better than that of commonly used phosphine-containing scale inhibitors. PASP has a synergistic effect when compounded with PBTCA.

2. Due to its green and environmentally friendly characteristics, PASP products can be used as new daily chemical additives and various non-toxic and pollution-free special fine chemicals.

3. PASP can be used as a nutrient absorption enhancer in agriculture to promote the production of vegetables, fruits, flowers and other crops. At the same time, it can be used with pesticides to improve the efficacy.

4. Packaging and storage

PASP is packed in plastic barrels, 25kg or 250kg per barrel, which can also be determined according to user needs. PASP is stored in a cool place indoors, and the storage period is ten months.

5. Safety protection

PASP is alkaline. Pay attention to labor protection when operating it. Avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
