ELECTOLESS METHOD FOR IN-LINE METALLIZATION OF SUBSTRATES BY SPRAYING THEM WITH PRIOR SURFACE TREATMENT AND DEVICE FOR IMPLEMENTING THE METHOD

摘要

It is an object of the present invention to provide a method for non-electrolytic metallization of a surface of a substrate by spraying at least one oxidation-reduction solution onto the surface of the substrate, which method is industrially applicable, , It is possible to process a large number of substrates, and optimization of adsorption and decoration appearance is possible. To achieve this, the method comprises the following steps: a) a physical treatment step or chemical treatment step to reduce the surface tension of the substrate before metallization, b) one or more oxidation-reduction solutions in the form of one or more aerosols A non-electrolytic metallization of the surface of the substrate treated in step a), and c) a top coating formation step on the metallized surface. It is another object of the present invention to provide a compact device for carrying out the method and a product to be obtained, in particular a cavity glass flask, an automobile part, a household electronic or airborne part, and a conductive track, An antenna or a coating for electromagnetic shielding.
