Abstract

The invention belongs to the technical field of saline and alkaline treatment, and concretely relates to a high-efficiency slow release scale inhibitor and a preparation method thereof. The scale inhibitor is formed by mixing a component A with a component B, and the component A is prepared through dissolving the following components, by weight, 10-30 parts of acrylic acid-sulfonic acid, 10-30 parts of citrate, 10-15 parts of polyaspartic acid, 10-15 parts of sodium gluconate, 1-10 parts of dimethyl sulfoxide, 0.1-1 part of n-hexylamine and 1-3 parts of an inorganic salt in bean slurry, and the concentration of the bean slurry is 100-300 g / L; the component B comprises, by weight, 15-30 parts of a polyacrylamide and / or acrylamide derivative polymer, 15-45 parts of an organic phosphoric acid scale inhibition single dose and 100 parts of water; and the high-efficiency slow release scale inhibitor is prepared through mixing the component A with the component B according to a mass ratio of (3-5):1. The scale inhibitor is suitable for being used in saline and alkaline land, and can effectively remove scales.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land treatment, and in particular relates to a high-efficiency slow-release scale inhibitor and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. Soil salinization refers to the process in which the soil type gradually changes to saline-alkali soil due to the accumulation of a large amount of saline-alkali ions in the soil, and its influencing factors include natural factors and human factors. ...
