                Polymaleic Acid (PMA)

Chemical formula:       --[CH-----CH--]m--
                              |      |
                              COOH   COOH


    Polymaleic Acid (PMA) was first synthesized by Prof. Li shouchun for to 

utilize as the water treatment Chemical in China.

It was an another research fruit after Polyacrylic Acid had been developed.

Performance :  Rapid adsorb on active sites of nuclei or crystal of alkaline scale and non-alkaline scale, distorting crystal lattice, changing scale to a no-adhesive sludge, thereby their deposition are inhibited ;  Polymaieic Acid can prevent the deposition of calcium phosphate and peel old scale off ;  Greater threshold property ;  Good dispersancy of inorganic and organic particulates ;  Stable and soluble at high and low pH level ;  Favorable compatibility and synergism ;  Nontoxic to human, animal and aquatic organisms.

Specification 

Application ----Scale inhibitor and Dispersing agent

• Calcium carbonate and calcium phosphate scale inhibitor for circulating cooling water treatment system of petrochemical industry, power plant and metallurgical industry ;

• Alkaline scale and non-alkaline scale inhibitor for desalinization of sea water, internal treatment of steam boiler, railway engine ,oil-field water including connate brine or injection fluid co-exists with oil in primary and secondary recovery processes of oil-well ;

• Excellent dispersing agent.

Packing and storage 

    200Kg or 25Kg in plastic drums or bottles; 

    Storage time--One year.
