Description
Technical field
The present invention relates to the treatment process of cold rolling zinc-plated production line electroplate liquid, specifically about a kind of method of removing iron ions in tinplating solution.
Background technology
The acid tin plating liquid of industrial application is mainly fluoroboric acid, benzene sulfonate, hydrogen halide and metilsulfate or these sour mixtures.Because these are all strongly-acid materials, the matrix of steel plate is resisted acidic medium in the initial stage ability of electroplating, and then makes the dissolved ferric iron of matrix.After iron concentration raises in plating solution, electroplating current density is narrowed; The increase of iron ion also can impel Sn
2+become Sn
4+ion, Sn
4+hydrolysis can generate a kind of oxidizing substance of insoluble, this insoluble oxide compound can be deposited on belt steel surface with a kind of precipitated form of mud shape, makes tin coating become porous.Therefore in tin plating solution, to reduce the content of iron ion as far as possible.
The method of removing at present iron ion in tin plating electrolyte mainly contains: the precipitator method, ion-exchange-resin process, freezing removal method are several.
The precipitator method: iron and tin are adjacent in movable metallic sequence list, the solubility product constant of the divalence of tin and tetravalence oxyhydroxide is far smaller than the divalence of corresponding iron and the solubility product constant of trivalent oxyhydroxide, inevitably loses part tin when therefore removing iron by the precipitator method.Be exactly specifically Bivalent Tin be to generate Sn (OH) at 1.2 o'clock at pH
2precipitation, and the throw out of iron ion produces precipitation when pH is 3, even be also to contain a certain amount of Sn (OH) in the Ferrox salt throw out obtaining under optimal pH
2mixture.And in the process of processing by the effect of a large amount of tin plating solution guarantee precipitation, in now a lot of documents and materials, all verified to change different pH values to remove the result that iron ion obtains be not satisfactory.
Ion-exchange-resin process: the countries such as current America and Europe have patent to announce can adopt strong-acid cation exchange, and this method is that tin plating electrolyte is passed through to strong-acid cation-exchange resin, by tin ion, ferrous ion and the absorption of harmful positively charged ion, finally separates with tin plating electrolyte.Principle is (taking storng-acid cation exchange resin as example):
nRSO
3H
++Me
n+→(RSO
3-)
nMe
n++nH
+
But this method exists two point defects: (1) at present the strong acid cation resin of applying is all the high chlorine resin after salt acid soak, it is that the form that reclaims iron protochloride by this acid solution that contains high chlorine is removed iron ion (United States Patent (USP) the 5th, 057, No. 290), like this chlorion is brought in tin plating solution, affected the performance of coating.(2) in tin plating solution, the content of iron contamination is higher adds long-term operation, and iron ion is cumulative in exchange resin, has occupied most of operating capacity of resin, causes resins exchange ability to decline, and exchange efficiency reduces.Sun resin is subject to the poisoning iron poisoning that is called of pollution of iron ion, needs a large amount of resins, and expense is just very high.
Cold method: in the PSA tin plating electrolyte that contains iron ion, in the lower situation of temperature, sulfocarbolic acid and iron can form throw out, around this principle separating phenol sulfonic acid iron and sulfocarbolic acid tin in the situation that of low temperature, this method can effectively be removed iron ion, also can not bring any impurity into solution.But this method equipment investment is larger, and use cost is also higher.
Therefore, in cold rolling zinc-plated production, need to provide a kind of method that can effectively remove cheaply iron ions in tinplating solution.
