Abstract
The invention discloses a scale and corrosion inhibitor. The scale and corrosion inhibitor is prepared from the following components by weight percent: 4-10% of silicon dioxide, 5-8% of ethylenediamine tetraacetic acid, 3-5% of polyacrylamide, 5-10% of Hydroxyethanediphosphonic acid, 3-7% of sodium lignin sulfonate, 6-12% of sodium alginate, 5-10% of diallyl dimethyl, 1-3% of a pH regulator and the balance of water. The scale and corrosion inhibitor disclosed by the invention is easy to prepare, good in stability and good in scale and corrosion inhibition property.
Description
Technical field
The present invention relates to chemical technology field, it is specifically related to a kind of anti-incrustation corrosion inhibitor.
Background technology
Inhibiter is a kind of when being present in environment (medium) with suitable concentration and form, it is possible to prevents or slows down the chemical substance of corrosion or the mixture of several chemical substance. In industry, the utilization of recirculated water is conducive to saving the cost of enterprise, improve the benefit of enterprise, but recirculated water in use there will be two problems, the evaporation of moisture when one, causes crystallization and the precipitation of salt, common are the incrustation scale such as calcium carbonate, Calucium Silicate powder most, the existence of incrustation scale greatly reduces heat transfer efficiency, it two is the corrosive nature of galvanic corrosion to equipment of recirculated water, and this kind of corrosion is fatal, gently then more exchange device; Heavy then injure human life, main at present adopt anti-incrustation corrosion inhibitor to be added in recirculated water, reduce the appearance of incrustation scale. But the composition of anti-incrustation corrosion inhibitor at present on the market is single, and descale effect is not good, especially process effect for the most common calcium carbonate etc. is not good, and this is the deficiencies in the prior art.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of new anti-incrustation corrosion inhibitor, and its scale inhibitor is effective, stability is strong.
The technical scheme that the present invention takes is:
A kind of anti-incrustation corrosion inhibitor, is made up of following component by weight percentage:
Silicon-dioxide 4-10%
Ethylenediamine tetraacetic acid (EDTA) 5-8%
Polyacrylamide 3-5%
1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 5-10%
Sodium lignosulfonate 3-7%
Sodium alginate 6-12%
Dimethyl diallyl 5-10%
PH conditioning agent 1-3%
Surplus is water.
Described PH conditioning agent is the oxyhydroxide of basic metal;
The PH value of described inhibiter is 9-12.
It is an advantage of the invention that:
1, the anti-incrustation corrosion inhibitor of the present invention can directly add use, it is not necessary to carries out service water mending alkali, regulating PH value, it may also be useful to convenient;
2, the anti-incrustation corrosion inhibitor of the present invention is not containing toxic compounds and phosphoric acid salt, pollution-free, is beneficial to environment protection;
3, the anti-incrustation corrosion inhibitor of the present invention is easily prepared, good stability, has good inhibition and scale-inhibiting properties.
