Description
Technical field
The present invention relates to metal surface treatment technology, particularly relate to the smokeless plating assistant agent of batch quantity hot dipping zinc.
The invention still further relates to a kind of using method of batch quantity hot dipping zinc plating assistant agent, belong to metallic substance technical field of anticorrosion.
Background technology
At metallic surface coated metal or other non-metallic coatings, the corrosion of matrix metal effectively can be prevented.Hot-dip plating metal technique comprise galvanizing, hot dip aluminum plating, hot dipping of zinc-aluminum alloy etc., mostly adopt solvent method, immerse by plating metal in the liquid metal bath of melting, after proposing work-piece cools, surface forms the very thin metal plating of one deck, thus corrosion resistance nature is improved greatly.
Solvent helps plating to be one important treatment process in galvanizing pre-treatment, and it not only can make up the deficiency that former procedure 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 has a significant impact zinc consumption cost.Tradition help depositing process be by pickling after steel piece immerse in the chloride zinc chloride ammonium quickening liquid of certain ingredients again, form the process of the thin zinc chloride ammonium salt film of one deck after proposition at article surface.Helping plating operation to play clean effect to steel piece surface, after removing pickling, remain in molysite or the oxide compound of article surface, making steel piece have larger surfactivity when entering zinc bath.The zinc chloride ammonium salt film that after helping plating, workpiece surface covers plays activation, is embodied in: time (1) lower than 200 DEG C, and workpiece surface forms a kind of approximate H
2[Zn (OH)
2cl
2] composite salt film, this is a kind of strong acid, thus ensures that workpiece surface cannot form oxide film and keep active state in drying process.(2) more than 200 DEG C, the NH in workpiece surface salt film
4cl at high temperature can resolve into NH
3and HCl, the now erosion of HCl to workpiece substrate accounts for leading, makes steel surface form oxide compound, keeps the active state of steel substrate.So be that ammonium chloride tool plays a very important role at galvanizing, proper use of ammonium chloride produces a very large impact galvanizing quality.
Although ammonium chloride helps plating to play a very important role, a large amount of flue dust can be produced owing to decomposing under the high temperature conditions, affect the health of workshop condition and workman.For the volume of smoke produced, most domestic enterprise does not adopt adequate measure to process.And in American-European countries, generally have employed the mode of flue dust collecting filtration treatment, produced flue dust is processed in the filter after air-bleed system is collected.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 scholar to propose to substitute ammonium chloride with NaCl and KCl, but research is closely under test, does not have actual industrial application.Pot galvanize practice shows, containing impurity such as NaCl or KCl of massfraction more than 1% in quickening liquid, can cause and help plating effect to decline, and causing plating leakage to return plating workpiece increases greatly.At present, be more focus on the low ammonium of low cigarette to help plating research and industrialization.Korea S helps the product of plating with or without ammonium, is dissected and draws wherein also containing more ammonium chloride composition, can not reach completely smokeless effect by formula.
Invented a kind of phytate plating resisting agent for heat zinc coating in Chinese patent (CN101122000A), plating assistant agent is made up of PHYTIC ACID ZINC SALT, borax, Sodium Fluoride, citric acid, oxalic acid, not containing ammonium chloride in plating assistant agent, is conducive to the improvement of Working environment.And for example, invent multifunctional plating assistant agent used for hot dipping additive in Chinese patent (CN101328568A), the additive be made up of has been added in the plating assistant agent be made up of Sodium Fluoride, aluminum fluoride, zinc chloride, ammonium chloride, potassium chlorate fluozirconate, Potassium monofluoride, sodium-chlor when improving hot dip process help plating effect quaternary cationics and polyoxyethylene ether nonionic surfactant.In addition, some other patent excessive use sodium-chlor, Repone K etc., control with great difficulty not produce plating leakage and return 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 chlorination ammonium salt, can greatly reduce the flue dust produced in hot galvanizing process, improve the environment in workshop.
Summary of the invention
