Abstract

POSTUPAK ZA PROIZVODNJU MREŽA OD PLEMENITIH METALA PROPUSNIH ZA GAS, ZA METALITIČKE PROCESE, za štrikanje /pletenje/ okruglih mreža radi primene kao katalizatora kod sagorevanja amonijaka i kao mreže za povraćaj platinskih metala, koriste se žice od paladijuma sa 2 do 15% nikla ili 2 do 15% bakra ili 2 do 25% nikla i bakra, prečnika 50 do 120 um, čvrstoće na kidanje od 900 do 1050 N/mm2 i granice razvlačenja od 0,5 do 3%. Pored toga potrebna je mašina za ravno pletenje sa 7 do 14 igala na col, pri čemu dužina petlji mora da bude izmedju 2 i 6 mm.
