Maleic acid - acrylic acid copolymer MA / AA Copolymer of Maleic and Acylic Acid (MA / AA) 【CAS】 *********6 Structure 1, product performance MA / AA is a low molecular weight polyelectrolyte, from maleic acid and acrylic acid copolymer obtained by a certain percentage, MA / AA pairs of carbonate, which are highly decentralized role, thermal stability, high temperature at **0 ℃ under adverse conditions such as the use of other water treatment chemicals have good compatibility and synergies. Including phosphate, including the scale of the formation of a good in vivo. As the MA / AA scale performance and high temperature performance, so widely used in low-pressure boiler, centralized heating, central air-conditioning and all kinds of circulating cooling water system. MA / AA can also be used in textile printing and dyeing industry as a chelating dispersant use. Second, quality indicators in line with GB / T ********1 Project Water Treatment Additive Appearance brownish yellow transparent liquid amber transparent liquid Solid content% ≥ *8 *0 Free monomer (as maleic acid count)% ≤ 9.0 5.0 Density (*0 ℃) g/cm3 ≥ 1.*8 1.*8 pH (1% aqueous solution) 2.0 - 3.0 2.0 ± 1.0 3, the application scope MA / AA loop at high temperature or low pressure boiler water systems, distillation systems used. With other organic phosphonate compound used, the dosage is generally 2 ~ *0mg / L. MA / AA for the textile printing and dyeing auxiliaries and to help by testing to determine if the dosage of lotion. 4, security and protection MA / AA as the acid, should avoid contact with skin, eyes and other contact, a large number of post-exposure application of water. 5, packaging and storage MA / AA as a plastic barrel, *5Kg or **0kg. Storage period *0 months.
