Description
Technical field
The present invention relates to metal surface treatment technology, relate in particular to the smokeless plating assistant agent of batch quantity hot dipping zinc.
The invention still further relates to a kind of batch quantity hot dipping zinc with the using method of plating assistant agent, belong to metallic substance aseptic technic field.
Background technology
At metallic surface coated metal or other non-metallic coatings, can effectively prevent the corrosion of matrix metal.Hot-dip plating metal technique comprise galvanizing, hot dip aluminum plating, hot dipping of zinc-aluminum alloy etc., mostly adopt solvent method, be about in the liquid metal bath of plating metal immersion melting, after proposing work-piece cools, the surface forms the very thin metal plating of one deck, thereby corrosion resistance nature is improved greatly.
It is one important treatment process in the galvanizing pre-treatment that solvent helps plating, and it not only can make up the deficiency that former procedures may exist, and can also activate steel surface, improves galvanizing quality.This is unexistent in other steel anti-corrosive techniques.Its quality not only directly affects quality of coating, also zinc consumption cost is had a significant impact.It is that the steel piece after pickling is immersed in the chloride zinc chloride ammonium quickening liquid of certain ingredients again that tradition helps depositing process, proposes rear process at the thin zinc chloride ammonium salt film of product surface formation one deck.Help the plating operation steel piece surface to be played the effect of cleaning, remove the molysite or the oxide compound that remain in the product surface after pickling, make steel piece have larger surfactivity when zinc is bathed entering.Help the zinc chloride ammonium salt film that workpiece surface covers after plating to play activation, be embodied in: ⑴ is during lower than 200 ℃, and workpiece surface forms a kind of approximate H
2[Zn (OH)
2Cl
2] the composite salt film, this is a kind of strong acid, thereby guarantees that workpiece surface can't form oxide film and keep active state in drying process.⑵ more than 200 ℃, the NH in workpiece surface salt film
4Cl can at high temperature resolve into NH
3And HCl, this moment, HCl accounted for leadingly to the erosion of workpiece substrate, made steel surface can't form oxide compound, kept the active state of steel substrate.So, be that the ammonium chloride tool plays a very important role, and correctly uses ammonium chloride that galvanizing quality is produced a very large impact at galvanizing.
Although ammonium chloride helps plating to play a very important role, can produce a large amount of flue dust owing to decomposing under hot conditions, affect workshop condition and workman's health.For the volume of smoke that produces, most domestic enterprise does not adopt adequate measure to process.And in American-European countries, generally having adopted the mode of flue dust collecting filtration treatment, the flue dust that produces after collecting, is processed in strainer air-bleed system.This flue dust collecting treatment system equipment is huge, operation energy consumption is higher.More to smokeless plating assistant agent research both at home and abroad, have the scholar to propose to substitute ammonium chloride with NaCl and KCl, but research does not have actual industrial application nearby in experimental stage.Pot galvanize practice shows, contains massfraction in quickening liquid and surpasses the impurity such as 1% NaCl or KCl, can cause and help the plating effect to descend, and causing plating leakage to return the plating workpiece increases greatly.At present, be more to focus on the low ammonium of low cigarette to help plating research and industrialization.Korea S has or not ammonium to help the product of plating, dissects to draw by formula and wherein also contains more ammonium chloride composition, can not reach smokeless effect fully.
Invented a kind of phytate plating resisting agent for heat zinc coating in Chinese patent (CN101122000A), plating assistant agent is comprised of PHYTIC ACID ZINC SALT, borax, Sodium Fluoride, citric acid, oxalic acid, does not contain ammonium chloride in plating assistant agent, is conducive to the improvement of Working environment.And for example, invented the multifunctional plating assistant agent used for hot dipping additive in Chinese patent (CN101328568A), the additive that is comprised of quaternary cationics and Soxylat A 25-7 nonionogenic tenside has been added to help the plating effect when improving hot dip process in the plating assistant agent that is formed by Sodium Fluoride, aluminum fluoride, zinc chloride, ammonium chloride, potassium chlorate fluozirconate, Potassium monofluoride, sodium-chlor.In addition, some other patent excessive use sodium-chlor, Repone K etc., control does not with great difficulty produce plating leakage and returns the problems such as plating, should not promote the use of.For this reason, the present invention proposes a kind of smokeless plating assistant agent without the chlorination ammonium salt, can greatly reduce the flue dust that produces in hot galvanizing process, improves the environment in workshop.
Summary of the invention
The invention provides the smokeless plating assistant agent of a kind of batch quantity hot dipping zinc.
The present invention also provides the using method of the smokeless plating assistant agent of a kind of batch quantity hot dipping zinc.
This smokeless plating assistant agent can reduce the flue dust that produces in the batch quantity hot dipping zinc process, improves the plating piece rate of drying, reduces the problem of quick-fried zinc and plating leakage, reduces unnecessary zinc consumption, saves production cost.
The technical solution used in the present invention is:
