Title (EN) METHOD FOR POWDER COATING OR FOR PRODUCING COMPOSITE MATERIALS, PREFERABLY WHEN PROCESSING PLASTICS OR SPRAY COMPACTING METALS
(FR) PROCÉDÉ DE REVÊTEMENT PAR POUDRE OU DE FABRICATION DE MATÉRIAUX COMPOSITES, DE PRÉFÉRENCE LORS DE LA FABRICATION DE PLASTIQUES OU DU FORMAGE PAR PULVÉRISATION DE MÉTAUX
(DE) VERFAHREN ZUM PULVERBESSCHICHTEN BZW. ZUR HERSTELLUNG VON VERBUNDWERKSTOFFEN, VORZUGSWEISE BEI DER VERARBEITUNG VON KUNSTSTOFFEN ODER BEIM SPRÜHKOMPAKTIEREN VON METALLEN
Abstract:
(EN) In a method for producing composite materials, preferably plastics, metered amounts of additional agents, preferably nanopowders and/or nanofibers, are admixed during production to form a homogenous matrix of the composite material to be produced. The additional agents are present at least partially in an agglomerated state before being admixed and are subsequently deagglomerated and added to the coating or to the plastic being processed to form the homogenous composite material. Said method is also suited for admixing metals during spray compacting or powder coating.
(FR) Procédé de fabrication de matériaux composites, de préférence de plastiques, selon lequel des quantités dosées d'additifs, de préférence des nanopoudres et/ou des nanofibres, sont ajoutées pendant la fabrication pour former une matrice homogène du matériau composite à fabriquer. Les additifs se présentent avant l'ajout au moins en partie à l'état aggloméré, sont ensuite désagglomérés et sont introduits dans le revêtement ou plus précisément dans le plastique se trouvant en fabrication pour former le matériau composite homogène. Ce procédé peut également être appliqué pour l'ajout de métaux lors du formage par pulvérisation ou pour le revêtement par poudre.
(DE) Bei einem Verfahren zur Herstellung von Verbundwerkstoffen, vorzugsweise von Kunststoffen, werden während der Erzeugung dosierte Mengen von Zusatzstoffen, vorzugsweise Nanopulver und/oder Nanofasern, zur Bildung einer homogenen Matrix des zu erzeugenden Verbundwerkstoffes beigemischt. Die Zusatzstoffe liegen vor dem Beimischen zumindest teilweise in einem agglomerierten Zustand vor und werden anschliessend deagglomeriert und der Beschichtung bzw. in den in Verarbeitung befindlichen Kunststoff zur Bildung des homogenen Verbundwerkstoffes zugeführt. Dieses Verfahren eignet sich auch für das Beimischen von Metallen beim Sprühkompaktieren oder zum Pulverbeschichten.
