Abstract

The invention discloses a pipeline descaling and antiscaling agent, which comprises various components and the parts by weight of the components are respectively: 4-10 parts by weight of pre-film agent, 3-9 parts by weight of deoxidizer, and scale inhibition 1-5 parts by weight of agent, 2-9 parts by weight of pH regulator, and 70-92 parts by weight of solvent. The pre-filming agent is composed of one or more of zinc sulfate, zinc chloride, and sodium silicate, and the deoxidizer is composed of one or more of azodicarbonamide, sodium sulfite, and isoascorbic acid. The scale inhibitor is composed of one or more of ammonium triacetate, disodium edetate, and sodium polyacrylate, and the pH regulator is composed of one or both of sodium hydroxide and potassium hydroxide Composition, described solvent is water. The descaling and antiscaling agent of the invention has strong stability, long service life, no corrosion effect on pipelines, environmental protection, low price and good effect of descaling and antiscaling.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a pipeline descaling and antiscaling agent used for water treatment, which can inhibit metal corrosion and remove or inhibit the generation of scale. Background technique [0002] During the use of the water treatment cycle, when the heat transfer surface of the water pipe is in a high-pressure or high-temperature environment, on the one hand, components such as calcium and magnesium contained in the water will be deposited on the heat transfer surface in the form of scale. Fouling on the surface will reduce thermal conductivity and increase energy consumption. At the same time, due to poor thermal conductivity, the temperature of the heating surface will increase, reducing the metal strength of the heating surface, thereby causing accidents; on the other hand, the pipeline will be corroded by water, which will affect the service life of the pipeline. .
