Novel environment-friendly compound corrosion and scale inhibitor

Abstract

A corrosion and scale inhibitor comprises, by weight, 0-3 parts of scale and corrosion inhibitors of an organic phosphonic series, 0-5.5 parts of dirt dispersion agents and aqueous dispersants of a polycarboxylic acid series and 0.5 part of zinc salt, and the weight ratio of the scale and corrosion inhibitors of the organic phosphonic series and the weight ratio of the dirt dispersion agents and the aqueous dispersants of the polycarboxylic acid series are not 0 at the same time. The compound corrosion and scale inhibitor is stable and reliable in performance, obvious scale and corrosion inhibition performance is achieved after the corrosion and scale inhibitor is used, and the corrosion and scale inhibitor is economical and environmentally friendly.

Description

technical field [0001] The invention relates to a corrosion and scale inhibitor, in particular to a novel environment-friendly composite corrosion and scale inhibitor. technical background [0002] Corrosion and scale inhibitors can effectively and reasonably slow down or prevent the corrosion of metals in circulating water media, and the addition of corrosion and scale inhibitors is very small. At present, most of the corrosion and scale inhibitors used at home and abroad are poisonous or harmful to the environment or have poor corrosion and scale inhibition effects. Although the anti-corrosion effect of organic compound corrosion inhibitors is quite good, the price is relatively expensive, so the development of an economical , efficient, new and environmentally friendly composite corrosion and scale inhibitors are the focus of current research. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and pr...
