Abstract
The invention provides a phosphorization solution. The phosphorization solution mainly consists of the following components in parts by weight in each unit volume: 40 parts of ferromanganese dihydrogen phosphate, 120 parts of zinc nitrate, 50 parts of manganese nitrate and 1 to 2 parts of ethylene diamine tetraacetic acid. The phosphorization solution is used for corrosion protection treatment of steel and iron pieces, enhances the bonding force between a coating film layer and a workpiece, improves the corrosion resistance of a coating on the surface of the workpiece after coating, and accords with the requirements of markets.
Description
Technical field
The present invention relates to the surface chemistry technical field, especially a kind of phosphatization liquid.
Background technology
Phosphating process before the assemblings such as steel pipe is in order to protect internal and external threads to assemble not thread gluing, to guarantee the internal thread non-corrosive, improving impact resistance.The phosphatization liquid that can get better plays important effect for the quality-guarantee of products such as steel pipe.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of phosphatization liquid.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of phosphatization liquid mainly is made up of phosphate dihydrogen manganese molysite, zinc nitrate, manganous nitrate and ethylenediamine tetraacetic acid (EDTA), by 40 parts in phosphate dihydrogen manganese molysite, 120 parts of zinc nitrates, 50 parts of manganous nitrates, ethylenediamine tetraacetic acid (EDTA) 1-2 part in its parts by weight per unit volume.
Preferably, above-mentioned phosphatization liquid is by 40 parts in phosphate dihydrogen manganese molysite, 120 parts of zinc nitrates, 50 parts of manganous nitrates, 1.5 parts of ethylenediamine tetraacetic acid (EDTA)s in its parts by weight per unit volume.
The collocation method of above-mentioned phosphatization liquid, concrete steps stir promptly for after by above-mentioned parts by weight phosphate dihydrogen manganese molysite, zinc nitrate, manganous nitrate and ethylenediamine tetraacetic acid (EDTA) being dissolved respectively.
Preferably, the collocation method of above-mentioned phosphatization liquid, the solution solvent temperature is 40-50 ℃.
Beneficial effect of the present invention:
Above-mentioned phosphatization liquid is used for the anti-corrosion protective treatment of steel part, strengthens bonding force between application rete and workpiece, improves the solidity to corrosion of surface coating after the application, meets the demand in market.
Embodiment
Below in conjunction with specific embodiment technical scheme of the present invention is further described.
Embodiment 1
A kind of phosphatization liquid, component is as follows:
Embodiment 2
A kind of phosphatization liquid, component is as follows:
Embodiment 3
A kind of phosphatization liquid, component is as follows:
The collocation method of the described phosphatization liquid of the foregoing description 1-3, concrete steps stir promptly for after according to the above ratio phosphate dihydrogen manganese molysite, zinc nitrate, manganous nitrate and ethylenediamine tetraacetic acid (EDTA) being dissolved respectively.In addition, the solution solvent temperature can be controlled in 40-50 ℃ with accelerate dissolution.
The described phosphatization liquid of the foregoing description 1-3, using method is:
The water (distilled water or deionized water) that adds 2/3 volume in the phosphatization groove adds fully dissolving in the phosphatization groove with above-mentioned phosphatization liquid, stirs and can use.
In addition, solution temperature can be heated to 40-50 ℃ with accelerate dissolution, and can be according to using needs to add water to the respective specified volume.
Need boil 0.5-1 hour before adding the phosphating solution work that water configures, add some again through oil removing and the clean iron filings of pickling, carry out " iron filings processing ", to increase the ferrous ion in the solution, iron filings can carry out the phosphatization of pickling-washing-more repeatedly, color up to phosphating solution becomes stable brown-green or pale brown look, can produce.
Above-mentioned detailed description of this a kind of phosphatization liquid being carried out with reference to embodiment; be illustrative rather than determinate; can list several embodiment according to institute's limited range,, should belong within protection scope of the present invention therefore in the variation and the modification that do not break away under the general plotting of the present invention.
