Abstract

The invention provides an anticorrosive antiscale agent for saline-alkali soil sprinkler irrigation equipment and a preparation method therefor. The anticorrosive antiscale agent comprises the following components in parts by weight: 24-26 parts of citric acid; 21-24 parts of tannin; 4-6 parts of glycine di(methylene phosphonic acids); 9-11 parts of polyepoxysuccinic acid; 6-8 parts of oxaloacetic acid; 1.5-2.5 parts of polyoxyethylene alkyl alcohol ether; 1-2 parts of N-vinyl pyrrolidone; 6-9 parts of sodium lignin sulfonate; 3-4 parts of potassium sorbate; and 40-50 parts of water. The preparation method of the anticorrosive antiscale agent comprises a step of preparing a citric acid aqueous solution: adding citric acid to weighted water, and stirring for 12 to 15 minutes at a rotational speed of 100 rpm under a condition of 20 to 70 DEG C. The anticorrosive antiscale agent of the invention has a scale inhibition rate of 98.2 to 98.6%.

Description

technical field [0001] The invention belongs to the technical field of sprinkler irrigation equipment, and relates to a special anticorrosion and scale inhibitor for sprinkler irrigation equipment, in particular to a special anticorrosion and scale inhibitor for sprinkler irrigation equipment in saline-alkali land and a preparation method thereof. Background technique [0002] Existing sprinkler irrigation equipment is mainly made up of parts such as water source power machine, water pump, pipeline system and nozzle. Water source power machine, water pump supplemented by pressure regulation and safety equipment constitute a sprinkler irrigation pump station. All levels of pipelines and gate valves, safety valves, and exhaust valves connected to the pumping station constitute a water delivery system. Spraying equipment includes nozzles or traveling devices on the final pipeline. [0003] In order to prevent the sprinkler irrigation equipment from producing insoluble inorgan...
