Abstract
The invention discloses the green corrosion inhibitor of a kind of hot dipping of zinc-aluminum alloy steel and application thereof, it be mainly composed of adenine phosphate and vitamin C, compound proportion is 1: 1～5: 1. Its application is: pickle is dilute hydrochloric acid or dilute sulfuric acid, and concentration is 0.1M-2M, adds corrosion inhibiter 0.01kg/m3-0.20kg/m3, temperature controls room temperature about 25 DEG C, adds zinc to be cleaned, allumen or galvanizing by dipping, zinc aluminum alloy coating steel, submergence 0.5h-3h. Product of the present invention is industrial acid-washed for zinc, allumen or galvanizing by dipping, zinc aluminum alloy coating steel and products thereof, general corrosion and the local corrosion of metal or coating in cleaning process can be prevented, the research of current similar restrainer is less, this product has low price, consumption is low, inhibition efficiency is high, the outstanding advantages that continuous action ability is strong. Product of the present invention is a kind of natural plant extracts, and environment and biological nontoxic is harmless, meets the trend of restrainer development, has a good application prospect.
Description
Technical field
The present invention relates to a kind of hot-dip steel natural green corrosion-retarding detergent, in order to prevent zinc, allumen or galvanizing by dipping, zinc aluminum alloy coating steel and products thereof general corrosion unnecessary in acid cleaning process and local corrosion, belong to industry cleaning link technical field.
Background technology
The application of zinc, allumen or galvanizing by dipping, zinc aluminum alloy coating steel and products thereof is more and more extensive, in its Product processing and application process, conventional dilute sulfuric acid or dilute hydrochloric acid carry out pickling, oxide-film or the corrosion product on surface can be removed, in order to avoid the generation consuming and preventing unwanted corrosion excessively of metal or acid in acid cleaning process, adding corrosion inhibiter in acid is effective means.
In restrainer conventional at present, mainly including the inorganic corrosion inhibiting compound containing poisonous chromate and some organophosphor compounds, its discharge is likely to result in the eutrophication of water body. The corrosion inhibiter of existing same domain mostly has toxic and side effects, does not possess the market competitiveness.
Therefore, developing new environmental protection, inexpensively, wide material sources, non-harmful restrainer is the new direction of current corrosion inhibiter exploitation.
Summary of the invention
It is an object of the invention to provide a kind of hot-dip steel natural green corrosion-retarding detergent in order to the general corrosion preventing zinc, allumen or galvanizing by dipping, zinc aluminum alloy coating steels and their products unnecessary in acid cleaning process and local corrosion.
The technical scheme is that a kind of hot-dip steel natural green corrosion-retarding detergent, it is mainly composed of adenine phosphate and vitamin C.Two kinds of materials belong to natural complex material, can extract in a large number from natural materials, are the materials that can not lack in human body, are widely used in pharmacology, nontoxic. Adenine phosphate is primarily present in the food such as Folium Camelliae sinensis and beet juice, belong to niacin and the riboflavin of B group's vitamin, it is the constituent of nucleic acid, participate in the synthesis of hereditary material, leucocyte hyperplasia can be promoted, make number of white blood cells increase, for preventing and treating the leukopenia that a variety of causes causes, the leukopenia caused during especially for tumor chemical therapy, is also used for acute myelogenous and reduces disease. Vitamin C, also known as ascorbic acid, is a kind of water soluble vitamins, and rich content in fruits and vegetables can be used for improving immunity, prophylaxis of cancer, heart disease, apoplexy, takes care of one's teeth and gingiva etc. Adenine phosphate and vitamin C are mixed with the compound proportion of 1: 1-5: 1, as the key component of corrosion inhibiter in abluent, adds density of corrosion inhibitor and range for 0.01kg/m3-0.20kg/m3; And the pickle that abluent uses is dilute hydrochloric acid or dilute sulfuric acid, its concentration is 0.1mol/L-2mol/L; Pickling temperature is 25 DEG C; Immerse metal 0.5h-3h to be cleaned.
Principles of the invention is in that: adenine phosphate and vitamin C molecules are the macrocyclic compound with heterocycle, molecule is contained within atom or the atomic groups such as heterocycle, nitrogen, oxygen, sulfur, allumen and zinc aluminum alloy coating steel surface can be effectively adsorbed in, play corrosion inhibition.
The invention has the beneficial effects as follows:
(1) adenine phosphate of the present invention and vitamin C sources are extensive, market quotes in 2012: adenine phosphate be 100-200 unit/kilogram, vitamin C be 50-100 unit/kilogram, very low cost.
(2) corrosion inhibiter component of the present invention is natural materials extract, for nontoxic green matter, compared with the corrosion inhibiter of current chemosynthesis, it is absent from the environmental problem after using, environment and biological nontoxic is harmless, meet the trend of restrainer development, have a good application prospect.
(3) present invention is used for the industrial acid-washed of all kinds of zinc, allumen or galvanizing by dipping, zinc aluminum alloy coating steel and products thereof, can effectively suppress metal or the coating unwanted corrosion in acid, compare with restrainer conventional at present, there is consumption low, inhibition efficiency is high, the outstanding advantages that continuous action ability is strong, can Reusability.
