Abstract
The invention relates to a formula of a magnesium alloy surface washing liquid, which mainly comprises the following components of: 40-99% of phosphoric acid, 0.01-0.1% of complexing agent and 0.9-59.99% of solvent. Using the formula to clean the surface of a magnesium alloy product can increase washing speed, shorten washing time, save labor hour and lower production cost; the raw materials for the formula have low harm to operators; and the formula can quickly wash away acid mud and oxides on the surface of a magnesium alloy to obtain the magnesium alloy product with brilliant white and uniform color, and simultaneously provide the surface with a uniform structure for the post-treatment of the magnesium alloy.
Description
[technical field]
The present invention relates to a kind of Mg alloy surface and whiten liquid formula, specially refer to the prescription that whitens liquid after a kind of Mg alloy surface etching.
[background technology]
Magnesium alloy application at present is very extensive, and its use range comprises motorcycle, portable type hand-operated tools, camera component and notebook computer shell.Domestic had the company and the turnout of a lot of production magnesium alloy notebook computer shells bigger, and this is that along with development of times, the portable magnesium-alloy material is with widespread use more because magnesium alloy has light and advantage such as to reclaim caused.
Because magnesium alloy is more active, be easy to generate the surface that one deck smut remains in workpiece after the etching, this will bring difficulty to aftertreatment, it will influence the outward appearance of product surface simultaneously, and etching part is owing to become with strong acid response organization that microcosmic is uneven to be there are differences with etching part not, so by carrying out whitening technique, can reduce the difference between them, for aftertreatment provides the relatively surface of homogeneous of condition of surface, etching demoulding institute residuals can be removed clean simultaneously, and the existing method that whitens mostly adopts and manually carries out wiping with rag or hairbrush, so that the smut of removing after the etching is residual, this method has been wasted great amount of manpower, material resources, the length that expends time in, and removing is clean inadequately.
[summary of the invention]
In view of this, the purpose of this invention is to provide a kind of Mg alloy surface and whiten liquid formula, utilize this prescription the magnesium-alloy material surface to be cleaned to have the speed of whitening fast, the time weak point can be saved man-hour, reduced production cost simultaneously, the raw materials used harm to operator of should filling a prescription simultaneously is little, and the sour mud and the oxide compound of flush away Mg alloy surface fast, the acquisition outward appearance is a brilliant white, the magnesium-alloy material of color even, the while also can provide the surface of weave construction homogeneous for the aftertreatment of magnesium alloy.
For achieving the above object, propose a kind of Mg alloy surface and whiten liquid formula, it mainly comprises:
Phosphatase 24 0-99%;
Complexing agent 0.01-0.1%;
Solvent 0.9-59.99%.
Preferably, described complexing agent is 6-hexylidene triamine pentamethylene phosphonic acids, Amino Trimethylene Phosphonic Acid, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid or other organic phospho acids.
Compared to prior art, Mg alloy surface of the present invention whitens liquid formula, and it is fast that it whitens speed, and the time pipe nipple is man-hour approximately, has reduced production cost simultaneously, fast the sour mud and the oxide compound of flush away Mg alloy surface.
[embodiment]
Further specify the present invention below by embodiment.
