Daaweynta dusha sare ee dhuumaha birta: Si loo hagaajiyo nolosha adeegga dhuumaha saliidda, daaweynta dusha sare waxaa sida caadiga ah loo sameeyaa si loo fududeeyo isku-dhafka adag ee tuubada birta iyo daahan anticorrosive. Hababka processing ee caadiga ah waa: nadiifinta, derusting qalab, pickling, rasaas qarxinta derusting. afar qaybood.1 nadiifinta Dufan, boodhka, saliidaha, walxaha organic ku dhejisan dusha sare ee tuubada birta, sida caadiga ah iyadoo la isticmaalayo dareeraha, emulsion si loo nadiifiyo dusha sare. Si kastaba ha ahaatee, miridhku, maqaarka oxide iyo alxanka dusha sare ee tuubada birta lama saari karo, sidaas darteed kuwa kale Hababka daawaynta ayaa loo baahan yahay.Qalabka miridhku ka saarida oxide dusha sare ee biibiile, miridhku, alxanka, waxay isticmaali kartaa burushka siliga birta si aad u nadiifiso oo u nadiifiso daweynta dusha sare Qalabaynta qalabka waxay gaari kartaa heerka Sa3. Haddii dusha sare ee tuubada birta ay ku xiran tahay maqaarka oksidheer gaar ahaan xooggan, waxaa laga yaabaa in aan macquul ahayn in laga saaro miridhku iyadoo la kaashanayo qalabka, markaa waxaan u baahanahay inaan helno siyaabo kale.3 pickling hababka caadiga ah ee pickling waxaa ka mid ah kiimiko iyo electrolysis. Laakiin kaliya pickling kiimikaad ayaa loo isticmaalaa ilaalinta daxalka dhuumaha la toogtay (cammuud) ka dib dib u habaynta.4 xabbad qarxin ah oo ka saarista miridhku by matoor awood sare wad xawaaraha-xawaaraha sare ee garbaha wareega, birta birta, toogashada birta, qaybta, macdanta iyo silig kale oo abrasive hoos tilmaanta ficilka centrifugal xoog buufin dusha birta birta iyo saarista tirada badan, si fiican ka saar miridhku, oxides iyo wasakh hal dhinac, dhinaca kale, bir bir ah oo hoos timaadda ficilka saamaynta rabshadaha abrasive iyo xoog is jiid jiid, si loo gaaro roughness labis loo baahan yahay.Among afarta hababka daaweynta, qarxinta rasaasta iyo derusting waa hab daaweyn ku habboon derusting tuubada.Guud ahaan, qarxinta rasaasta iyo dildilaaca ayaa inta badan loo isticmaalaa daawaynta gudaha gudaha ee tuubada birta, iyo qarxinta rasaasta iyo burburinta ayaa inta badan loo isticmaalaa daawaynta dusha sare ee tuubada birta.
