Description
Technical field
The present invention relates to a kind of anti-corrosion of metal etching technique.
Background technology
In recent years, along with industrial expansion, environmental pollution constantly aggravates, and the etching problem of ferrous materials is more and more serious, thereby the protection of material comes into one's own gradually.According to statistics, annual in the world metal material amount of scrapping because of corrosion is approximately 1/2 of metal annual production, even the metal material that corrosion is scrapped can reclaim 2/3, annual still have the metal loss that is equivalent to annual production 10% to fall.The value of corrosion loss can not be only calculated with the quality of the metal that lost still more, and the energy that is consumed in the time of should comprising metal smelting is so the manufacturing value of the metal material scrapped of being corroded is often costly many than metal itself.Therefore, for the normal operation of saving ferrous materials and guaranteeing to produce is resolved the anticorrosion problem of ferrous materials, just meet China's STRATEGIES OF SUSTAINABLE DEVELOPMENT.
The effective ways of control ferrous materials corrosion have two big classes at present: the one, and the alloying of metal, the 2nd, coat of metal anticorrosion.
Metal alloyization is that ferrous materials is made the stainless steel that contains the special metal element, to reach the purpose that improves corrosion resistance, because the complex manufacturing of these steel grades costs an arm and a leg, so its popularization is restricted.
Coat of metal anticorrosion mainly is to adopt metallic zinc as coating, adopts metallic zinc coating anti-corrosion method to mainly contain calorizing, galvanoplastic, plating method, hot spray process, and the developed recently mechanical plating of getting up etc.The secondary production cycle of plating is long, surface quality is low, cause plating leakage easily; The porosity of hot spray process is higher and utilization rate zinc is lower.The used anode material major part of hot spray process, galvanoplastic and mechanical plating method is a zinc; thereby the standard electrode potential of zinc is lower; zinc coating on the iron-based is anode coating in general corrosive medium; matrix is played the electrochemical protection effect; and zinc to form on the surface in corrosive environment be the corrosivity good film, not only protected zinc layer itself, also protected steel substrate; and zinc coating is nontoxic, cheap, barrier propterty is good, therefore zinc-platedly occupies an important position in anticorrosion.But it is anticorrosion to adopt zinc-plated method to carry out, and can make that the anti-salinization performance of product is not high.
Summary of the invention
For solving the problem that prior art exists, the invention provides a kind of anti-corrosion method that is used for metal, adopt the slaine voltinism of this method preparation can be high, durability, corrosion resistance are strong.
The present invention be realize like this "
A kind of anti-corrosion method for metal, described method is drawn together the following step:
Pre-treatment: surface of the work is carried out pickling, phosphatization and washing;
Preliminary drying: workpiece is carried out preliminary drying in 320 ℃ of-370 ℃ of temperature ranges, the preliminary drying time is 1-5 minute;
Soak and mould: will soak molding powder and be coated in workpiece and need soak the face of moulding, and soak and mould to the scheduled time, and, remove surplus powder the workpiece vibrations;
Solidify: the workpiece that will soak after moulding is cured in 180-200 ℃ of scope, and be 1-5 minute hardening time.
Optionally, the described molding powder that soaks is that PVC soaks molding powder or PE soaks molding powder.
Anti-corrosion method for metal provided by the invention is simple to operate, cost is low, and the product corrosion resistance that adopts described method to make is strong, and anti-salinization performance height has prolonged service life, makes the scope of application of metal more strengthen.
The specific embodiment
Describe the present invention in detail below in conjunction with specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
Embodiment 1:
The anti-corrosion method for metal that present embodiment provides, specifically:
Pre-treatment: surface of the work is carried out pickling, phosphatization and washing; Can adopt hydrochloric acid or sulfuric acid that surface of the work is carried out acid pickling and rust removing, then surface of the work be carried out phosphatization, water cleans up surface of the work then;
Preliminary drying: workpiece is carried out preliminary drying under 320 ℃ of temperature conditions, the preliminary drying time is 1-5 minute; The preliminary drying time can decide according to the size and the shape of workpiece;
Soak and mould: will soak molding powder and be coated in workpiece and need soak the face of moulding, and soak and mould to the scheduled time, and, remove surplus powder the workpiece vibrations; Soaking when moulding, soaking molding powder around heated metal clings, metal temperature is high more, it is long more to soak the material time, and gained soaks that to mould layer thick more, so mould layer thickness and workpiece shape and set and soak the time of moulding according to required soaking; Soak mould end after, the molding powder vibrations of soaking that surface of the work is unnecessary are removed, and can strengthen the gloss and the levelling of surface of the work;
Solidify: the workpiece that will soak after moulding is cured in 200 ℃ of scopes, and be 1-5 minute hardening time, and solidification process will soak molding powder and workpiece combines firmly.
In soaking the process of moulding, can adopt auxiliary equipment with piece-holder, can be with piece-holder before pre-treatment, also can be after pre-treatment holding workpiece, decide on the shape of workpiece.
The described moulding material that soaks can be various plastic raw materials, and preferred PVC soaks molding powder or PE soaks molding powder in the present embodiment.
Embodiment 2:
As embodiment 1 described anti-corrosion method for metal, the difference of present embodiment and embodiment 1 is: described workpiece carries out preliminary drying under 370 ℃ of conditions, the preliminary drying time is preferably 5 minutes, is cured under 180 ℃ of conditions, is preferably 3 minutes hardening time.
Embodiment 3:
As embodiment 1 described anti-corrosion method for metal, the difference of present embodiment and embodiment 1 is: described workpiece carries out preliminary drying under 350 ℃ of conditions, is cured under 160 ℃ of conditions.
More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
