NC-301(ZFI21NC) PAA & NC-302(ZFI22NC) PAAS

(1)Molecular Weight & Chemical Structure:

PAA:   (C3H4O2)n        -[-CH2- C H-]n-                  CAS: 9007-20-9
                                                |   
                                               C OOH
 
PAAS: (C3H3NaO2)n    CAS: 9003-04-7

(2)Properties:

The polyacrylic acid and its sodium salt are among the most widely used polycarboxylic acid Chemicals forwater treatment purposes today. They can be used alone in the concentration range of 2-8ppm,preferably4ppm.And they can also be used together with organic phosphonate    esters and poly phosphates,with good synchronistic effects. They can be used in alkaline.Conditions and high concentration without any scale formation in operation.And besides,their disposal will cause no pollution problem.
