Abstract

The invention relates to a brine pipeline scale inhibitor, composed of hydroxyethylidene-1,1-diphosphonic acid, an acrylic acid-2-acrylamide-2-methylpropanesulfonic acid copolymer, polyaspartic acid (sodium) and polyacrylic acid. The brine pipeline scale inhibitor is capable of reducing the scaling tendency of salts such as calcium sulfate and calcium carbonate, forming stable complexes, promoting dissolving reaction and gradually dissolving the previous scale layer under excellent chelating, low limit inhibition and lattice distortion actions of organic phosphine and by means of excellent dispersing performance of the polymer to scales; and the brine pipeline scale inhibitor has scale inhibition and descaling functions and thereby is a good scale inhibitor for a brine delivery system.

Description

【Technical field】 [0001] The invention relates to a chemical agent, in particular to a brine pipeline scale inhibitor, its application and its application method, and belongs to the technical field of scale inhibitor and dispersant. 【Background technique】 [0002] Brine salt production process Due to the high salt content of brine, brine will also form a large amount of deposition and scaling on the surface of the pipeline during the transportation process, which will greatly affect the transportation capacity and service life of the pipeline. Therefore, whether it is in the evaporation tank, the heating room, or the formation of scale deposits on the surface of the pipeline, the end result is reduced production capacity and reduced profitability. [0003] In the patent CN102351324A, it is mentioned that a polymer is used as a dispersant, which can play a better dispersing effect, but is weak in chelating and descaling ability. In the patent CN102060312A, it is mentioned to...
