polishing aluminum diamond plate

Polishing aluminum diamond plate can remove the friction streaks, thermal deformation layer, oxide film layer and so on that may exist on the aluminum plate, so that the rough surface of the aluminum plate tends to be smooth, and at the same time, it can improve the specular reflection performance and mechanical strength performance of the aluminum plate.polishing-aluminum-diamond-plate-1

polishing aluminum diamond plate features

When polishing aluminum diamond plate, the polishing performance of pure aluminum is better. Although the polishing performance of aluminum-magnesium alloy and aluminum-silicon alloy is not as good as that of pure aluminum, it is generally good. In order to obtain a high-standard bright finish, in addition to choosing high-quality aluminum diamond plate substrates, a combination of mechanical polishing, chemical polishing and electrochemical polishing is often used. There is an article on how to polish aluminum diamond plate.


Suggestions for using polishing aluminum diamond plate

The polishing aluminum diamond plate used in cold storage, carriages, and ship bilges is usually 1xxx series aluminum plate with a thickness of 3.0mm. This series of aluminum plates does not need to be suspended and does not bear weight. So there is no need to choose high thickness, high hardness aluminum plate.

For special places (such as places that need to be suspended in the air, or where there is a high degree of corrosion or easy to rust and corrosion), it is recommended to use 5052 or 6061 anti-rust and anti-aluminum for polishing aluminum diamond plate. This series of anti-slip aluminum plates have excellent anti-rust and corrosion resistance.

For the places that are suspended in the air and need to be stepped on by the staff, it is recommended to use a higher-strength alloy series for polishing aluminum diamond plate, and the thickness is not less than 6.0mm. This series and thickness of the anti-skid aluminum plate can guarantee the staff’s maximum, and at the same time Ensure the service life of the non-slip aluminum plate.

Possible deficiencies of chemical polishing aluminum diamond plate

1. The brightness of the chemical polishing aluminum diamond plate does not reach the expected goal. The reason can be analyzed from two aspects: the production process of the special aluminum material and the chemical polishing process. It is recommended to use aluminum ingots with an aluminum purity of 99.70% and above to produce special aluminum materials; quality control in the aluminum processing technology lays the foundation for chemical polishing to obtain a high-gloss surface.

2. Insufficient time for polishing aluminum diamond plate, insufficient temperature, insufficient stirring, and aging of the bath liquid will also make the surface brightness of chemical polishing insufficient. The relative density of the bath liquid is relatively large, which prevents the aluminum material from floating out of the liquid surface of the polishing bath liquid, resulting in insufficient brightness of the upper aluminum material. The influence of water causes insufficient brightness, which is often overlooked. It is best to use dry aluminum to enter the chemical polishing bath to prevent the introduction of moisture.

3. A layer of white deposit is attached to the polished aluminum surface after chemical polishing aluminum diamond plate, and the distribution is uneven, and the surface of the aluminum material at the bottom of the attachment may be corroded. Usually, this defect is caused by too high amount of dissolved aluminum in the chemical polishing bath, and measures need to be taken to adjust the amount of dissolved aluminum in the bath to a normal range.
