1, Forskellig natur
\n1. Bejdsning: en metode til at rense oxider og rust p\u00e5 metaloverflader med en syreopl\u00f8sning
\n2. Passivering: den proces, hvor et metal oxideres ved en st\u00e6rk oxidant eller elektrokemisk metode for at g\u00f8re dets overflade inaktiv, dvs. passiv.<\/p>\n
2\u3001 Forskellige principper
\n1. Bejdsning: Generelt er dele neds\u00e6nket i nogle sure vandige opl\u00f8sninger s\u00e5som svovlsyre for at fjerne oxider eller andre film p\u00e5 overfladen. Det er forberedelsesprocessen af metaldele f\u00f8r anden overfladebehandling (s\u00e5som plettering) eller det mellemliggende trin af overfladebehandling.
\n2.Passivering: efter at et lag af oxidfilm eller hydroxid er dannet p\u00e5 metaloverfladen, p\u00e5virker stigningen af p\u00e5f\u00f8rt sp\u00e6nding ikke str\u00f8mmen, opl\u00f8sningen af metalioner stoppes, og den har korrosionsbestandighed.<\/p>\n

\n2. Passivering: f\u00f8r bejdsning og passivering af metaldele, bekr\u00e6ft, om deres overflader er rene. Hvis der er pletter eller fedt, skal de renses mekanisk med tilsvarende organiske opl\u00f8sningsmidler. Fordi pletter og fedt p\u00e5 overfladen vil p\u00e5virke kvaliteten af bejdsning og passivering.<\/p>\n
Det er vigtigt at v\u00e6lge den passende overfladebehandlingsproces for tilpassede dele, hvilket ikke kun vil p\u00e5virke produktets samlede effekt, men ogs\u00e5 p\u00e5virke projektomkostningerne.
