Abstract
A coating of sea ship and its hot spray technology for preventing corrosion and living marine things' parasitism features that tin-brass which has anticorrosion nature and the oxide of heavy metal (CO2O) that is toxic and not dssolved easily are proportioned and then form a durable protecting layer on sea ship by instantaneous high temp raised during hot spray. The coating has the advantages of high anticorrosion nature, inhibiting parasitism of living marine things but not killing them, no pollution to seawater and durable effective period (7 years).
Description
The present invention be marine ship anticorrosion, prevent that marine life from adhering to parasitic plating field, specifically, be a kind of marine ship anticorrosion, prevent that marine life from adhering to parasitic coating and thermal spraying craft.
As everyone knows, marine ship of all times anticorrosion, prevent that marine life from adhering to parasitic conventional practice, adopt the way that applies paint (restitution lacquer), but validity period does not all surpass 1 year always, need twice protective treatment of do to the marine ship of special purpose is annual.Had modern age the people to utilize electroplating principle, and a lead was suspended from makes negative electrode in the seawater, hull is as anode; under the electrical forces effect, negative electrode dissolves in the seawater, and part is elegant to hull; thereby sacrificed negative electrode lead and protected the hull anode not to be corroded, so claim " sacrificing cathode method ".Apply for many years and find that lead ion enters seawater in a large number and causes severe contamination to seawater, however to marine life to adhere to parasitism still powerless.There is the people in paint, to add sterilant in recent years, adheres to parasitic problem to scheme solving marine life, but, make its validity period also surpass only 1 year eventually because of the solubility of sterilant.Thereby to this relevant department of National Bureau of Oceanography regulation, the above marine ship of ton is annual must do a rotproofing.The last depressed place of these large ships, surface-conditioning apply paint, the whole process of plunging into the commercial sea need be suspended the bimestrial time, consume lot of manpower and material resources for this reason, and year in and year out.External situation is also pessimistic.
Purpose of the present invention, overcome the deficiency of above-mentioned Technology exactly, provide a kind of long-acting, reliable, can prevent that seawater from effectively preventing again that to the corrosion of hull marine life from adhering to parasitism, the outer field coating layer of marine ship underwater portion of polluted seawater not again simultaneously in a large number at underwater body.
For achieving the above object, a kind of hull is anticorrosion, prevents that marine life from adhering to parasitic coating, adopts the thermal spraying craft spraying plating at boats and ships underwater portion outside surface, and the basal component of coating is:
Copper (Cu): 48%-60%; Tin (Sn): 0.6%-1%
Red copper oxide (Cu
2O): 5%-7%; Zinc oxide (ZnO): 5%-8%
Stannic oxide (SnO
2): 0.1%-0.6%; Zinc (Zn): 31%-36%
Above-mentioned coating of the present invention, adopt the metal fever spraying plating process to realize that its spraying plating process is as follows:
1, preparation of raw material: 5 microns of one-ton brass (HSn62-1) granularities
Red copper oxide (Cu
2O) granularity is 5 microns
Proportioning: HSn62-1: Cu
2O=95%: 5% mixes.
2, hull pre-treatment; Mechanical removal hull bottom marine life, bivalves etc., row sandblasts with sander again, removes used paint layer, exposes metal body and after the hull outside surface is got pit, blows off residual thing with high-pressure air.
3, construction: after the thermospraying machine is connected oxycetylene gas, regulate flame temperature to 1500-2000 ℃, and regulate shower nozzle and deck of boat distance, to making the ejection waste heat make the hull surface instantaneous temperature at 150-200 ℃, then reinforced examination is sprayed in hopper, can construct after reaching requirement.
4, form the condition of coating; Guarantee 1300 ℃-1500 ℃ of raw material powder instantaneous temperatures, 150 ℃-200 ℃ of hull surface instantaneous temperatures, thickness of coating δ=0.2-0.3mm.
The present invention is owing to adopt above-mentioned technology spraying plating, and the sticking power of coating and matrix is quite firm, facts have proved, to being carried out press working (as roll bending, bending) and hammering by the sheet material after the plating, coating deforms in company with matrix and is provided with and aliquation occurs, comes off phenomenons such as crackle.
Be described in detail below in conjunction with embodiment:
The present invention adopts one-ton brass HSn62-1: Red copper oxide Cu
2O=95%: 5% batching is made four test specimens (20 * 40) processing condition with above-mentioned with thermal spraying craft.Do corrosion-resistant respectively and antibiont adheres to parasitic experiment.Test specimen is incubated 20 ℃+0.2 ℃ immersion through 3 months in concentrated 15 times seawater, finds no evidence of corrosion.Other two test specimens are put into the culture dish that nutritive medium is housed, and inoculate green mucormycosis, cultivate through being incubated 20 ℃ three months, and mycelia bulging ware body in the ware, and do not find on the test specimen that mycelia adheres to.Above-mentioned craftwork manufacture test specimen is plunged into the commercial sea, go through sea water immersion under the natural condition that picks up for many years, do not find that sea-water corrosion and marine life adhere to parasitism.Can draw sure conclusion today, coating of the present invention, and it prevents sea-water corrosion, prevents that marine life from adhering to parasitic ability more than 10 years.Consider the difference of suitability for industrialized production and test conditions, conservative this coating validity period of saying was safe in 7 years.Why coating of the present invention has strong anti-seawater corrosion and mariner growth prevent to adhere to parasitic ability, be because HSn62-1 itself has very strong rotproofness, be commonly used to make the boats and ships component that directly contact with seawater, add that itself to have plasticity good, the characteristic that intensity is high, this has determined the coating that is formed by it not come off with the matrix distortion.Little toxicity of Red copper oxide has been destroyed the living environment of marine life, thereby marine life dare not adhere to parasitism, but coating can not killed marine life.The insoluble of Red copper oxide has determined coating long-acting, and polluted seawater not.
