Abstract
The invention discloses acidic cleaner for removing an oxide scale and oily carbon deposition mixing layer on the surface of aluminum. By the cleaner, the oxide scale and oily carbon deposition mixing layer on the surface of aluminum, which is caused by high temperature owning to drawing, can be completely removed, and the cleaner does not erode the surface of aluminum and has simple operation and low cost, and the acidic cleaner contains the following raw materials in percentage by weight: 1-40 percent of mixed acid, 1-10 percent of corrosion inhibition additives, 0.1-10 percent of nonionic surfactant, 0.1-10 percent of anionic surfactant, 0.1-15 percent of oxo solvent, 0.5-5 percent of thickener, and water less than or equal to 90 percent, and the PH value is less than 2.0.
Description
Technical field:
The present invention relates to a kind of acidic cleaner of removing aluminium material surface oxide skin and oiliness carbon distribution, especially a kind of aluminium material surface of can thoroughly removing produces oxidation and the oiliness carbon distribution mixolimnion that high temperature causes because of drawing, do not corrode aluminium material surface again, the acidic cleaner of removing aluminium material surface oxide skin easy and simple to handle, with low cost and oiliness carbon distribution mixolimnion.
Background technology:
When aluminium contacted with air, its surface can form one deck oxide skin protective membrane as quick as thought, so aluminium is placed also not perishable variable color naturally in air.The oxide film on aluminium surface and most of acidic substance do not react; React with high alkali liquid or hot sig water, but easy turning black and changing color.The processing mode of aluminium has casting, drawing moulding etc., need releasing agent or drawing oil be removed after the moulding at die surface coating release agent or drawing oil in the course of processing again.But, because aluminium produces moment high temperature in drawing process, the drawing lubrication fry dried food ingredients that makes aluminium material surface is given birth to carbonization generate carbon distribution, combine with the oxide skin of aluminium material surface again, promptly form the thicker mixed membranous layer that is difficult to remove.At present, clean for the many strong acid of the cleaning of surface oxidation and oiliness carbon distribution mixolimnion with high density, soaked 8～20 hours such as the vitriol oil, or soak again after being heated to the vitriol oil more than 60 ℃, then can comparatively fast remove, but this processing mode is not only time-consuming, power consumption, and to the aluminium seriously corroded, simultaneously owing to being the strong acid of high density, so operator's danger is very big., if with the reaction of rare strong acid treatment then very slow, more be difficult to take effect with weak acid.What also have cleans with caustic soda, still, also will remove the black film that produces because of alkaline etching with nitric acid after the cleaning, complex process, wastes time and energy.
Summary of the invention:
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, provide a kind of aluminium material surface of can thoroughly removing to produce oxidation and the oiliness carbon distribution mixolimnion that high temperature causes because of drawing, do not corrode aluminium material surface again, the slightly acidic clean-out system of removing aluminium material surface oxide skin easy and simple to handle, with low cost and oiliness carbon distribution mixolimnion.
