Acrylicacid,maleicacidpolymer - Use
Open Data Verified Data
maleic anhydride-acrylic acid copolymer has strong dispersion effect on carbonate and the like, high thermal stability, and can be used under severe conditions such as high temperature of 300 ℃, it has good compatibility and synergistic effect with other water treatment agents. Widely used in low-pressure boilers, central heating, central air conditioning and various types of circulating cooling water systems. The maleic anhydride-acrylic acid copolymer has excellent scale inhibition performance and high temperature resistance, and has a good inhibitory effect on the formation of scale including phosphate. The maleic anhydride-acrylic acid copolymer can also be used as a chelating dispersant in the textile printing and dyeing industry. With other organic phosphate compound use, the dosage is generally in 2~10mg/L.

Acrylicacid,maleicacidpolymer - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| introduction | maleic acid acrylic acid copolymer is a low molecular weight polyelectrolyte, which is prepared by copolymerization of maleic acid and acrylic acid in a certain proportion. this product has a strong dispersion effect on carbonates, high thermal stability, can be used under harsh conditions such as 300 ℃ high temperature, and has good compatibility and synergistic effect with other water treatment agents. It can be used in high-temperature circulating water systems or low-pressure boilers and distillation systems. It is used in combination with other organic phosphonates, and the dosage is generally 2~10mg/L. |
| use | as textile printing and dyeing auxiliaries and builders. It is used for cooling water circulation to effectively inhibit the formation of various scales. Can be used at high temperature of 300 ℃. Can be used in combination with organic phosphorus salt. General dosage 10-6~10-5. |
| production method | maleic anhydride, acrylic acid and deionized water are put into a reaction kettle in a certain proportion, stirred and dissolved to form a uniform solution, then the initiator xylene peroxide is added, and the temperature is gradually increased to 80 ℃, the temperature is kept for 1h, and the unreacted monomer is evaporated under reduced pressure. Filtered finished product. |
