Performance and Applications

PASP is a water-soluble polymer, a new type of green water treatment agent, with the characteristics of no phosphorus, non-toxic, pollution-free and fully biodegradable. It has extremely strong chelating ability for ions, has dual functions of corrosion inhibition and scale inhibition, has good scale inhibition effect on scaling salts such as calcium carbonate, and the scale inhibition rate for calcium carbonate can reach ≥95%. At the same time, it 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 from discharge.

Technical Specifications

Usage Method

As a scale and corrosion inhibitor, PASP is widely used in industrial circulating water, boiler water, reverse osmosis water, oilfield water and other water treatment fields, and has excellent performance in systems with high hardness, high alkalinity, high pH and high concentration cycles. Its scale inhibition effect is better than that of common phosphorus-containing scale inhibitors. PASP has a synergistic effect when compounded with PBTCA.

Due to its green and environmentally friendly properties, PASP can be used as a new type of daily chemical auxiliary and various non-toxic and pollution-free special fine chemicals.

In agriculture, PASP can be used as a nutrient absorption enhancer to promote the production of vegetables, fruits, flowers and other crops, and can improve the efficacy when used together with pesticides.

Packaging and Storage

PASP is packed in plastic drums, Standard capacities: 25kg, 250kg, 1250kg (IBC tank).Note: Packaging weight can be adjusted according to customer requirements. Store in a cool indoor place. The shelf life is twelve months.

Safety Protection

PASP is alkaline. Pay attention to labor protection during operation. Avoid contact with skin, eyes, etc. In case of contact, rinse immediately with plenty of clean water.
