Requirements for core material of aluminum honeycomb panel

The production of honeycomb panels without aluminum honeycomb core. The factors that affect the performance of honeycomb core mainly include aluminum foil, node adhesive and honeycomb core specifications and other parameters. Aluminum honeycomb core specifications are determined by the thickness of aluminum foil and honeycomb cell size. Different specifications of aluminum honeycomb have different densities and different mechanical properties, and their cost also varies greatly. Honeycomb core specifications can be expressed in two ways: honeycomb cell inscribed circle diameter (English units) and aluminum foil thickness/cell side length (metric units). China's national standard is expressed in aluminum foil thickness/cell side length.

The strength of the honeycomb core should be strictly tested and evaluated, and the node strength data should be ≥ 2.0N/mm. The nodal adhesive should be epoxy modified high temperature curing adhesive, which not only provides sufficient bonding strength but also has excellent environmental resistance and high and low temperature resistance. The general adhesive is often easy to make the honeycomb core degumming due to low strength, resulting in overall damage and instability.

Aluminum honeycomb panel decorative panel selection is also very important, its material is generally selected 3003, 5005 and other brands, low alloy composition of 1100 sheet less used. Decorative surface by spraying or roller coating form, coating for polyester or fluorocarbon paint, exterior wall board is best choice of spraying board, and requires more than three coating, paint layer thickness ≥ 40μm, so as to ensure the durability of the coating.

In order to meet the national quality requirements for aluminum honeycomb panels, the various components of aluminum honeycomb panels are strictly controlled, especially aluminum panels and aluminum honeycomb cores.
