The Improvement Guideline for Electroplating Process for Aluminum and Aluminum Alloys
Do you know the traditional aluminum and aluminum alloy plating?
There are deficiencies. With the improvement of technology, there is obvious improvement about aluminum and aluminum alloy plating technology. Pingguo Jianfeng Aluminum Co., Ltd. is an enterprise specialized in manufacturing various kinds of top-grade powder-spraying aluminum moulding profiles, inheriting the advanced production technology, we make efforts, relying on more than a decade of experience in aluminium profile processing, to develop, and by now we have possessed tens of national patented technologies, which make our products in the leading position in the market.
Aluminum and aluminum alloy electrolysis in the electrolyte can form a coating, but the coating binding force is not strong, easy to peel. Therefore, aluminum can be first deposited in the aqueous solution containing zinc oxide compounds and then electroplating, this method is either zinc displacement or deposition. It is also possible to first obtain a thin porous oxide film on the surface of aluminum and aluminum alloys by anodizing the power supply to perform electroplating.
Aluminum and aluminum alloy electroplating processes are pre-plated, electroplated and post-plated. Pre-plating treatment is the most critical process related to the quality of electroplated products. Its main purpose is to remove the grease on the surface of aluminum and aluminum alloys, naturally forming an oxide film and other dirt.
Conventional general processes are: degreasing-washing-demineralization-washing-pickling-washing-activation-washing-primary zincation-washing-removal-zinc-washing-secondary zincation-washing-neutral nickel-plating-washing- Subsequent plating.
There is also a wave of the anodized film instead of zinc immersion process in the subsequent plating.
As the traditional pre-treatment of aluminum and aluminum alloys agrees with the above deficiencies, they must be improved.
The new process aims at the actual defects of the current aluminum alloy electroplating, combined with the special physical and chemical properties of the aluminum alloy itself, and it is improved on the basis of the original technology, Pingguo Jianfeng Aluminum Co., Ltd has many professional superficial processing technologies, such as Electrophoresis Coating Aluminum, Powder Coating Aluminum and so on.
And the following advantages are specifically:
