Acrylic acid Polymers
CAS NO.9003-01-4
Performance:
Polyacrylic acid and its sodium salt are one of the most widely used polycarboxylic acid water treatment agents, and can be used alone. Generally, the concentration is (2-8) mg/L. The most suitable concentration is generally 4mg / L, can also be combined with organic phosphonates and organic phosphates, polyphosphates, have a good synergistic effect, can run under alkaline and high concentration multiples without scaling . Polyacrylic acid does not pollute the environment when it is discharged.
Uses:
1. Used to prevent scaling in circulating cooling water systems such as power plants, steel plants, chemical plants, fertilizer plants, refineries and air conditioning systems.
2. Softening of industrial water such as printing and dyeing and dispersing detergent in washing process
