DESCRIPTION

Acrylic acid-maleic acid copolymer sodium salt (PMA-40)

Product physical and chemical indicators:

Appearance:Colorless or yellowish, transparent, viscous liquid

Solid content:40±1%

Sulfate content: no

pH: 6-8 (1% aqueous solution)

According to the different ratio of raw materials, it is divided into the following three products:

AA:MA	Weight average molecular weight	Viscosity mpa·s（25℃）	Calcium chelation force mgCaCO₃/g	Calcium dispersion mgCaCO₃/g	Monomer residue Ppm
7:3	60000-80000	2000～3000	≥360	≥260	≤3000
6:4	30000-50000	1000～1500	≥340	≥280	≤5000
5:5	10000-20000	500～1000	≥300	≥300	≤5000

Product features:

1. It has strong dispersing effect on carbonates, etc., has high thermal stability, can be used under severe conditions such as high temperature of 300 °C, and has good compatibility and synergistic effect with other water treatment agents. It has a good inhibitory effect on the formation of scale including phosphate.

2. Excellent anti-scaling performance and high temperature resistance, widely used in low-pressure boilers, central heating, central air conditioning and various types of circulating cooling water systems.
