PROCEDE DE FABRICATION DE PANNEAUX EN ALUMINIUM A TENUE A LA CORROSION AMELIOREE EN MILIEU AQUEUX

摘要

The process for manufacturing aluminium panels comprises the surface preparation of two sheets made of aluminium alloy, the deposition on one of the sheets of an anti-weld ink in reserve zones corresponding to the circuit design, the bonding of the sheets to each other by rolling, and the expansion of the channels corresponding to the non-welded zones by means of a pressurized fluid. In this process, said ink comprises the following constituents: a) a mineral filler in the divided state; b) an organic thickener; c) a corrosion resistance promoter; and d) a solvent comprising at least 50% water by weight.
