Product Description
Product Details
Introduction and Application
AA/AMPS is a copolymer of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). Because the molecular structure contains carboxylic acid groups with good scale inhibition and dispersibility and strong polar sulfonic acid groups, it can improve calcium tolerance and has a significant scale inhibition effect on calcium phosphate, calcium carbonate, zinc scale, etc. in water, preventing the deposition of iron oxide, especially for calcium phosphate. The scale inhibition rate is high and the dispersibility is excellent. When combined with organic phosphine, the synergistic effect is obvious. It is particularly suitable for water with high pH,high alkalinity and high hardness, and is one of the most ideal scale inhibitors and dispersants for achieving high concentration multiples. AA/AMPS can also be used as a textile printing and dyeing auxiliary and a scale inhibitor for pulp in papermaking systems.
Application:
1. Industrial circulating cooling water system
2. Oilfield wastewater reinjection system
3. Metallurgical system circulating water treatment
4. Steel plant leaching cooling water treatment
5. Textile printing and dyeing auxiliaries
6. Papermaking system pulp scale inhibitor

Usage:
Acrylic acid-2-acrylamide-2-methylpropanesulfonic acid copolymer can be used in combination with organic phosphonates and zinc salts, and is suitable for pH conditions of 7.0 to 9.5.
