3.Using method:
PAA (polyacrylic acid) is often used in formulas with other water treatment agents. The specific formula and dosage are determined by experiments based on on-site water quality and equipment material conditions. If used alone, the general concentration is 1-15mg/L; when used in other industries such as concrete water-reducing agent, printing and dyeing, the dosage should be determined based on tests.
3.Package and Storage:
200L plastic drum or IBC(1000L);
Store in a cool and ventilated place indoors, storage period is 1 year.
4. Safety protection
PAA is week acidic, pay attention to labor protection during operation. Avoid contact with skin, eyes, etc. After contact, rinse with plenty of water.
