Pakati siyana Kudzingwa pezvakaitwa, Stainless simbi vari ainyanya kukanda kubudikidza inivhesitimendi Kudzingwa kana vakarasika wakisi Kudzingwa muitiro, nekuti ane yakakwirira zvikuru nemazvo uye ndokusaka inivhesitimendi Kudzingwa anonziwo zvakarurama Kudzingwa.
Isimbi isina tsvina ndiyo chidimbu chesimbi isina simbi uye isina asidi. Inodaidzwa kuti simbi isina simbi inopesana neasina simba inokanganisa midhiya, mweya, uye mvura. Corrosion simbi inonzi acid-inodzivirira simbi.
Nekuda kwemusiyano mukuumbwa kwemakemikari pakati peyakajairika simbi isina simbi uye simbi isingadzivirire acid, yavo ngura kuramba kwakasiyana. Yakajairika simbi isina simbi kazhinji haigadzikane nemakemikari midhiya ngura, nepo asidi-isina simbi simbi kazhinji isingakunde. Izwi rekuti “simbi isina chinhu” haringorevi chete simbi imwe chete, asi rinorevawo simbi dzinopfuura zana dzemaindasitiri. Imwe neimwe simbi isina tsvina yakagadzirwa ine kuita kwakanaka mune yayo chaiyo yekushandisa munda.
Stainless simbi inowanzo kuve yakakamurwa kuita martensitic simbi isina simbi, ferritic simbi isina simbi, austenitic simbi isina simbi, austenitic-ferritic (duplex) simbi isina tsvina uye kunaya kuomesa simbi isina simbi zvichienderana nenyika ye microstructure. Uye zvakare, maererano nemakemikari akaumbwa, inogona kukamurwa kuita chromium simbi isina chinhu, chromium nickel simbi isina simbi uye chromium manganese nitrogen simbi isina simbi, nezvimwe.
Mukukanda kugadzirwa, akawanda esimbi simbi castings anopedzwa nekudyara kukanda. Pemvura Stainless simbi castings zvinoberekwa inivhesitimendi Kudzingwa iri anotsvedzerera uye ndeiya yakaita zvakarurama zviri nyore kudzora. Ehe, mutengo wekudyara kukanda simbi dzesimbi zvikamu hwakareba zvakanyanya uchienzaniswa nemamwe maitiro uye zvigadzirwa.
Investment kuraswa, inonziwo chaiyo kukanda kana kurasikirwa wakisi kukanda, inowanzoshandiswa sezvo ichipa asymmetrical Kudzingwa neakajeka kwazvo ruzivo rwekuti kugadzirwa neinodhura. Maitiro acho anosanganisira kuburitsa simbi inokanda uchishandisa fekitori inogadzirwa kubva kune wakisi replica pateni. Matanho anobatanidzwa mukuita kana kurasa wakisi kukanda ndeaya:
Gadzira wakisi pateni kana mufananidzo
Svetura wakisi pateni
• Isa wakisi pateni
Bvisa wakisi pateni nekuipisa iyo (mukati mevira kana mumvura inopisa) kugadzira chakuvhuvhu.
• Kumanikidza simbi yakanyungudutswa kudira muforoma
• Kutonhora nekusimbisa
• Bvisa sprue kubva mukukanda
• Pedzisa nekupurisha iyo yakapera mari yekukanda
