Abstract
The invention belongs to the technical field of water treatment, and in particular relates to a reverse osmosis scale inhibition and dispersion agent and a preparation method thereof. The reverse osmosis scale inhibition and dispersion agent is prepared by compounding the following materials in percentage by weight: 10 to 30 percent of 2-phosphono-1,2,4-tricarboxylic acid butane, 10 to 20 percent of amino tris(methylene phosphonic acid), 20 to 40 percent of sulfonate copolymer, 2 to 5 percent of polyaspartic acid and the balance of deionized water. The preparation method comprises the following steps of: adding the deionized water into a reaction kettle, adding the 2-phosphono-1,2,4-tricarboxylic acid butane, the amino tris(methylene phosphonic acid), the sulfonate copolymer and the polyaspartic acid, and stirring at normal temperature for 55 to 65 minutes. The components have high compatibility, complementarity and synergy, the reverse osmosis scale inhibition and dispersion agent replaces an imported product, the operating cost of a reverse osmosis device is reduced, the normal operation of the reverse osmosis device is ensured, and the preparation method is simple, and easy to implement.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of reverse osmosis dirt dispersion agent and preparation method thereof.
