Abstract

The invention provides a special scale inhibitor for a saline-alkali soil moistube and a preparation method for the special scale inhibitor. The special scale inhibitor consists of the following components in parts by weight: 25-28 parts of 2-hydroxy phosphono-acetic acid, 27-30 parts of oxalic acid, 11-13 parts of citric acid, 9-12 parts of oxaloacetic acid, 4-8 parts of sodium lignin sulfonate, 9-10 parts of polyepoxysuccinic acid, 4-6 parts of nipasol, 1.5-3.5 parts of sodium diacetate, 1-2 parts of allyl polyether , 1-3 parts of dimethyl sulfoxide and 60-70 parts of water. The scale inhibitor needs to be diluted in use by adding water which is 5 times the amount of the scale inhibitor. The scale inhibitor disclosed by the invention is high in scale inhibiting ratio of 98.1-99.1%, wherein a calcium carbonate scale inhibiting ratio is 98.2-98.9%, a magnesium carbonate scale inhibiting ratio is 98.5-99.5%, a calcium sulfate scale inhibiting ratio is 99.2-100%, and a barium carbonate scale inhibiting ratio is 99.4-100%.

Description

technical field [0001] The invention belongs to the technical field of micro-moisture irrigation, and relates to a special anticorrosion and scale inhibitor for micro-moisture pipes, in particular to a special scale inhibitor for micro-moisture pipes in saline-alkali land and a preparation method thereof. Background technique [0002] The micro-running tube is a hose-shaped water feeder made of a semi-permeable membrane as the core material. It has a double-layer structure. Huge micropores, making full use of the characteristics of semi-permeable membranes, is a new type of water feeder made by introducing membrane technology into the irrigation field, which can further migrate to the soil, make the soil moist, and play the role of irrigation. [0003] In order to prevent micro-moisture pipes from scaling and depositing on the system pipe parts due to insoluble inorganic salts in saline-alkali water during the irrigation process of saline-alkali land, blocking the micro-mois...
