Aluminum polishing technology

The role of chemical polishing

Aluminum anodic oxidation pretreatment, aluminum chemical oxidation pretreatment, providing light appearance, will tell from aluminium, the polishing performance of pure aluminum is best, polishing of aluminum silicon alloy is the worst. In order to achieve high standards and shining finishing surface, in addition to choose high purity aluminum, often by mechanical polishing, chemical polishing and way of the combination of electrochemical polishing.

Chemical polishing aluminum surface level off is smooth, can remove the aluminum surface streak of mild mould marks and scratches, can remove mechanical polishing may be generated in the friction stripe, thermal deformation layer, oxide film layer, etc., lead to the smooth and rough surface, aluminum mirror reflection performance can be improved at the same time, improve the brightness.

Chemical polishing process factor

(1): Loading material: the quantity of material should be decreased, the distance between aluminum material should be increased, the incline should be increased, and the gas will escape as soon as possible. The chemical polishing liquid is very heavy, aluminum is very light, and in the process of polishing, it is also made to prevent the aluminum from floating on the surface, causing the brightness to be uneven. A conductive beam should be added to prevent the aluminum from floating. The decorative surface of the high brightness requirement should be made out of the outside, and the gas will escape as soon as possible. The loading should be firm, put on the non-decorative surface when using the fixture, avoid leaving marks.

(2): chemical cleaning degreasing: the treatment of non-fat products containing surfactant is commonly used in water base.

(3): stirring: a method of mixing or mixing of gas or liquid. Make sure the gas escapes as soon as possible to avoid the accumulation of gas. When the gas accumulates to a certain amount, the air bubbles up, causing the aluminum surface to form a gas stripe, and the appropriate stirring can make the polishing more uniform.

(4): time: usually one to three minutes, but depending on the amount of aluminum soluble, surface gloss, temperature, etc.

(5): temperature: the effect of temperature on the polishing and surface quality has very important influence, improve the efficiency of polishing speed, temperature but produce more gas, liquid temperature shoulds not be too high, new aluminum content reaches a certain balance after can be appropriately raise the temperature, generally no more than 105 degrees.

(6): aluminum transfer: when the acid concentration is high, the acid content decreases rapidly and can easily cause corrosion.

(7): wash: it is recommended to wash the water with air and suggest the water temperature is about 40 degrees. It is recommended to wash with circulating water.

(8): in addition to ash: some aluminum surfaces have been polished and the layers of dust have to be removed.

(9): nitric acid containing the control: if nitric acid is too high, you can see the light blue to orange, the color of the rainbow, or with a little corrosion defects such as rough. The nitric acid content is too low, you can see the defects such as low brightness of aluminum of chemical polishing, or small white fixtures. General control in 2% 8% normalized bath, per shift production to do normal add after eight hours, to supplement consumption, usually nitric acid consumption of chemical polishing bath consumption 1% 2% (volume)

(10): relative density: low density may make the polished surface less luminous, or cause a deterioration in brightness; The density is too high, and the right energy of the right soluble aluminum is too high.
