Environmental Friendly Chromate-free Passivated Aluminum Honeycomb Corel is made of chromate-free treated aluminum foil bonded by special purpose adhesive. The performance of the aluminum honeycomb core is determined by the properties of aluminum foil, special purpose chemical adhesive and the size and configuration of the core.
The Chromate-free passivation can have the following benefits:
The conversion layers take on different colour, depending on operating conditions.
Corrosion resistance is an inverse function of the iron and copper content.
The average electrical resistivity of a yellow film is low enough for earth-connections use in many applications.
The conductivity of the films for radio frequency currents is high enough, allowing use for waveguides and the like.
The most significant one is it is environmental friendly.
Process
General process of an aluminum honeycomb core initiated with an aluminum foil roll and surely the foil is specially treated.
The adhesive tapes are printed to the foil surface with the intervals and width pre-determined by the cell size and strength requirement.
The foil paper is cut into required size to be piled up on the stacking table with equipment and man supervision on the adhesive tape positioning.
These stacked loose blocks should be pressed in a heated press to cure the adhesive so that the sheets of foil are bonded together to hardened block.
The aluminum honeycomb block can be cut into slices with the height of the slices tailored to customized requirements.
Finally, no matter it is done in supplier’s plant or at client’s workshop, the honeycomb should be expanded before forming aluminum honeycomb panel.
The following materials are for forming honeycomb cores:
1. Aluminum foil
Regularly, 3003H19/5052H18 aluminum alloy foils after strict surface treatment are used for producing aluminum honeycomb core.
2. Special Purpose Chemical Adhesive
Modified epoxy glue for high temperature cure process can provide not only sufficient bonding strength, but also environmental resistance and high or low temperature resistant properties. The joint strength of aluminum honeycomb core is the keypoint of evaluating the core’s performance. The minimum requirement should be more than 2.0N/mm.
