| titleOfInvention | A kind of reverse osmosis membrane antiscalant and preparation method thereof |
| abstract | The application relates to the technical field of scale inhibitors, and specifically discloses a formula of a reverse osmosis membrane scale inhibitor and a preparation method thereof. A reverse osmosis membrane antiscalant comprises 20-30 parts of polyaspartic acid, 20-30 parts of tannin, 10-20 parts of alkyl epoxy carboxylate, 8-12 parts of non-oxidizing bactericide, deionized water 100 parts, the polyaspartic acid is sulfonic acid modified polyaspartic acid. The preparation method optimizes the addition sequence of each component and the pH value of the scale inhibitor to ensure effective and uniform dispersion of each component and improve the stability of each component. The reverse osmosis membrane scale inhibitor of the present application has the characteristics of good scale inhibition effect, strong resistance to hard water, green and pollution-free. |
