Abstract
The invention discloses a scale and corrosion inhibitor. The scale and corrosion inhibitor is prepared from the following raw materials in parts by weight: 20 to 25 parts of amino tri(methylene phosphonic acid), 30 to 35 parts of 1-hydroxyethane 1,1-diphosphonic acid, 15 to 20 parts of amino tri(methylene phosphonic acid), 3 to 5 parts of sodium ethylenediamine tetramethylene phosphonate, 2 to 5 parts of polyacrylic acid, 2 to 6 parts of lauric acid, 1 to 3 parts of polyaspartic acid, 1 to 3 parts of 2-hydroxyphosphonoacetic acid, 1 to 3 parts of methyl benzotriazole, 2 to 6 parts of sodium gluconate, 6 to 8 parts of zinc powder, 0.5 to 1 part of surfactant, and 60 to 70 parts of deionized water. The scale and corrosion inhibitor disclosed by the invention has a favorable restraining effect on calcium and calcium carbonate, and has the capabilities of dispersing slightly soluble inorganic salts in water and protecting metal against corrosion and rusting.
Description
Technical field
The invention belongs to corrosion inhibition for metal technical field, be specifically related to a kind of anti-incrustation corrosion inhibitor.
Background technology
Plant equipment inevitably contacts with some aqueous solutions in manufacture, processing, production, running, not only can erode metallic surfaces, also can form some incrustation scales, modal have an incrustation scale such as calcium carbonate, calcium silicates, therefore conventionally need to add antisludging agent, calcium carbonate, calcium phosphate are had to remarkable scale inhibition and dispersion performance, reduce the appearance of incrustation scale, anti-incrustation corrosion inhibitor composition is in the market single, and descale effect, corrosion mitigating effect are bad.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of anti-incrustation corrosion inhibitor, calcium, calcium carbonate are had to good resistancing action, the slightly solubility inorganic salts in can disperse water, prevent that metal erosion from getting rusty.
Technical scheme of the present invention is: a kind of anti-incrustation corrosion inhibitor, is made up of the raw material of following parts by weight: ATMP 20-25 part, HEDP 30-35 part, ATMP 15-20 part, sodium ethylenediamine tetramethylenephosphonate 3-5 part, polyacrylic acid 2-5 part, laurate 2-6 part, poly-aspartate 1-3 part, 2-HPAA 1-3 part, TTA 1-3 part, gluconic acid sodium salt 2-6 part, zinc powder 6-8 part, surfactant 0.5-1 part, deionized water 60-70 part.
Compared with prior art, the invention has the advantages that: calcium, calcium carbonate are had to good resistancing action, the slightly solubility inorganic salts in energy disperse water, prevention or interference slightly solubility inorganic salts are in precipitation, the fouling of metal surface, reduce the appearance of incrustation scale, prevent that metal erosion from getting rusty simultaneously.
