Abstract

The invention discloses a special scale inhibitor for a saline and alkaline land spray irrigation device. The special scale inhibitor is prepared from the raw materials in parts by weight, 8-15 parts of hydroxy ethylene sodium phosphate, 3-5 parts of sodium polyacrylate, 1-3 parts of mercaptobenzothiazole sodium, 5-10 parts of sodium hexametaphosphate, 3-7 parts of ethylene diamine tetramethylidene phosphoric acid sodium, 1-2 parts of benzotriazole sodium, 6-15 parts of methyl benzo three nitrogen, 6-10 parts of polyvinylpyrrolidone, 4-8 parts of lignin and the rest water. The lignin is a dispersive scale inhibition material and added into the scale inhibitor, corrosion-inhibition effects of the scale inhibitor are improved, the lignin and the mercaptobenzothiazole sodium are matched to act, the device is effectively protected, ions in water are spread and can flow along with the water, the sodium hexametaphosphate is provided with a plurality of coordinate bonds, the coordinate bonds can simultaneously combine with a plurality of ions, so that descaling can be effectively avoided, and the scale inhibitor is stable in performance and has good heat stability.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a special scale inhibitor for sprinkler irrigation equipment in saline-alkali land and a preparation method thereof. Background technique [0002] Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects on metal equipment. From the perspective of the mechanism of action Speaking, the role of scale inhibitors can be divided into three parts: chelation, dispersion and lattice distortion. And in the laboratory evaluation test, dispersion is the remedial measure of chelation, and lattice distortion is the remedial measure of dispersion. In the area of ​​saline-alkali land, the water contains a large number of metal ion groups and non-metal ion groups, which are very easy to The formation of sedime...
