Description
Technical field
The present invention relates to a kind of detection methods of zinc-plated mode, and in particular to a kind of to identify rope making with coating iron content
The detection method of wire galvanization mode.
Background technique
Electrogalvanizing is also named cold galvanizing, is that steel are put into ingredient using electrolysis installation after oil removing, pickling for zinc salt
In solution, and the cathode of electrolysis installation is connected, places zine plate on the opposite of pipe fitting, the anode for being connected to electrolysis installation connects electricity
Source, using electric current from positive to the displacement of cathode, Zn in electrolyte2+Nucleating growth deposits on substrate under current potential effect
Zinc coat is formed, in this process without the diffusion process between zinc-iron.So theoretically coating should be pure zinc coat, do not have
There is ferro element.The conventional zinc-plated amount of galvanizing technique is seldom, and the corrosion resistance of itself is more many than galvanizing by dipping difference, in fact,
The effect of electrogalvanizing, some are suitable with antirust oil is applied at most, or even are not so good as.
Galvanizing and galvanizing by dipping are also named in hot galvanizing, are a kind of effective anti-corrosion of metal modes, are the steel parts after derusting
It immerses in the zinc liquid of 500 DEG C or so thawings, is the process for forming zinc-iron alloys layer between iron matrix and outmost pure zinc layer,
Zinc-iron alloys layer to be combined well between iron and pure zinc layer, so being divided into two layers from theoretical coating, since thermal expansion occurs
It dissipates, so there are ferro elements in coating.And the adhesive force of zinc-iron alloys layer is very strong, it is not easy to fall off, to play anti-corrosion mesh
, it is mainly used on the metal structure facility of every profession and trade.Hot galvanized layer forming process is substantially iron matrix and outmost pure zinc
The process of zinc-iron alloys is formed between layer, its adhesive force very also determines that its corrosion resistance is very good by force, hot-galvanized steel
Although the phenomenon that product also corrodes, technology, hygienic requirements can satisfy in very long service life.
In view of the difference of electrogalvanizing and the anti-corrosion capability of hot galvanizing, use occasion etc., it is desirable to by steel product
Electrogalvanizing and hot galvanizing mode identification gradually standard market, constantly improve that steel product is existing in terms of quality safety to ask
Topic, avoids obscuring between hot galvanizing and electrogalvanizing, adulterate.It is well known that electrogalvanizing and the hot galvanizing of steel product
Using if it happens obscuring, less serious case is unable to reach expected requirement, severe one leads to personnel and property loss, especially more great
Application field.Such as: the industries such as chemical industry equipment, PETROLEUM PROCESSING, seafari, metal structure, power Transmission, shipbuilding once occur
Corrosion failure, it will unpredictable loss is brought, so, it should the test method for identifying the two is established, in case misuse, causes
Irreversible loss.
In general, the difference of electrogalvanizing and hot galvanizing includes:
1, application environment is different: electrogalvanizing is used for the general etch-proof occasion of every profession and trade, and hot galvanizing is used for outdoor requirement
The strong occasion of corrosion resistance；
2, etch-proof protective capability is different: electrogalvanizing is strong not as good as hot galvanizing protective capability；
3, thickness is different: plating zinc coating is relatively thin, and hot dip galvanizing coating is thicker；
4, appearance is different: electrogalvanizing flat appearance is bright, the coarse gloss difference of hot galvanizing appearance.
In the past, what the differentiation of electrogalvanizing and hot galvanizing steel relied primarily on is exactly organoleptic examination spangle, and spangle refers to hot dip
Zinc steel are after the pull-out of new pot, with the appearance of the crystal grain formed after zinc layers cooled and solidified.Therefore, hot galvanizing steel surface
It is usually coarse, there is typical spangle feature, and electrogalvanizing steel surface is smooth.But with the raising of new technology, even same
The electrogalvanizing of factory cannot be distinguished from the appearance with hot galvanizing steel, and hot galvanizing steel have not had the typical case of common spangle
Feature, especially present unleaded zinc liquid produce the hot galvanizing steel without spangle or small zinc flower.Sometimes hot galvanizing steel surface ratio
Electrogalvanizing steel surface more highlights, and reflective is more preferable.In addition, due to the progress of air knife technology, small zinc flower and skill is produced without spangle
Art constantly improve, and the surface quality of hot galvanizing steel substantially increases.Sometimes one piece of hot-dip galvanizing sheet steel and one piece of electrogalvanizing
Steel plate is put together, and it is plated steel sheet that be difficult to distinguish which block, which be hot-dip galvanizing sheet steel, which block, so, it at present cannot be with appearance
It both distinguishes, the research for both being bound to carry out to distinguish from theoretical source.Especially rope making electrogalvanizing and hot-dip galvanizing steel wire,
Perhaps, thick diameter wire has a little spangle, and finer wire surface is not seen in the presence of there is no spangles, even more can not be from sense organ
It is distinguish.And thickness is different, and commonly identifies a kind of means of zinc-plated mode, but the plating of some electrogalvanizings is also very thick,
But from corrosion-resistant angle or not as good as hot galvanizing, it may be said that distinguishing from thickness is electrogalvanizing or hot galvanizing is undesirable
, it is distinguish so new method should be formulated.New detection method is exactly by electrogalvanizing and the zinc-plated mode of hot galvanizing
Difference causes the chemical element in coating different, so the present invention, which is established, identifies the two with chemical method, it is special according to formulating
The test method of chemical component detection, using device inductance coupled plasma optical emission spectrometer or Atomic Absorption Spectrometer into
Iron content in row detection coating.According to whether detecting ferro element in coating or by its range identify it is zinc-plated in a manner of.
