NC-305(ZF211NC) Acrylic acid-methyl acrylate copolymer(Equal to N-7319)
(1) Chemical Structure:
      [C3H4O2]n[C4H7O2]m
 
      -[-CH-CH2-CH-CH2-]n-
          |             |
          COOH    COOH 
 
(2)Properties:
  a  Its anti-scaling property and dispersion property are as good as the similar products called N-7319 of Nalco company.
  b   The product shows certain synchronistic effect when used together with N-7350. It can help increase the dispersion scaling-prevention and corrosion inhibiting effects of N-7350 and exhibits obvious dispersion effect against silt deposition caused by clay and sand, and organic materials.
 
(3 )Use:
a. In the open circulating cooling water systems, this product can replace poly-acrylic acid products. And when used as scaling-prevent and dispersion agent, he product is especially good for the windy and dusty northern areas in China and for places where high suspended and organic material content in water is expected.
b. The product can be substituted for HPMA, for applications in low-presure boilers and steam locomotives.
