Chitsulo chosapanga dzimbiri ndi chinthu chodabwitsa chomwe chimagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, chifukwa cha mawonekedwe ake apadera komanso magwiridwe antchito osayerekezeka.Koma kodi mumadziwa kuti pali chinsinsi chobisika chosungira magwiridwe ake ndi moyo wautali?Chinsinsi ichi chagona mu njira yotchedwa passivation.

Mawu Oyamba pa Stainless Steel

Kumvetsetsa mphamvu ya passivation kumayamba ndi kuyamikira maziko a zitsulo zosapanga dzimbiri palokha.Chitsulo chosapanga dzimbiri sichinthu chophweka;

ndi aloyi wopangidwa kuchokera ku chitsulo, carbon, ndi mlingo wowolowa manja wa chromium.

Zomwe Zimapanga Chitsulo Chosapanga dzimbiri Chapadera

Wosewera wamkulu munkhani yachitsulo chosapanga dzimbiri ndi chromium.Ikakhala ndi okosijeni, chromium imapanga kagawo kakang'ono kosawoneka ka chromium

oxide pamwamba pa chitsulo.Chigawochi sichimangokhala, kutanthauza kuti sichichita ndi china chilichonse.

1. Kumvetsetsa Kukaniza kwa Corrosion

Chromium oxide ndi mngelo woteteza chitsulo chosapanga dzimbiri.Imateteza dzimbiri ndi dzimbiri, zomwe ndi mbuna zofala pazitsulo zina zambiri.

Kukana kwa dzimbiri kumeneku kumapereka chitsulo chosapanga dzimbiri dzina lake komanso kugwiritsidwa ntchito kwake kofala.

2. Udindo wa Passivation mu Stainless Steel

Tsopano, tiyeni tilowe mumutu waukulu - passivation.Passivation ndi njira yamankhwala yomwe imakulitsa kusanjika komwe kumachitika mwachilengedwe kwa chromium oxide.

Izi zimapangitsa kuti chitsulocho chisamachite dzimbiri komanso dzimbiri.

3. Sayansi Imene Imachititsa Chidwi

Pa passivation, zitsulo zosapanga dzimbiri zimathandizidwa ndi njira yofatsa ya asidi.Izi zimachotsa chitsulo chaulere ndi zonyansa zina pamwamba,

zomwe zitha kusokoneza mapangidwe a chromium oxide layer.

Kodi mungafune kudziwa chifukwa chake zitsulo zosapanga dzimbiri zimafunika kuti zidutse?

Poyamba, tiyenera kudziwa tanthauzo la passivation-stainless chitsulo? The passivation zitsulo zosapanga dzimbiri amatanthauza kuti pamwamba zitsulo zosapanga dzimbiri zimachita ndi passivation wothandizira kupanga khola passivation filimu amateteza zosapanga dzimbiri gawo lapansi kuti dzimbiri. chifukwa cha okosijeni ndi dzimbiri.Kuchita dzimbiri kwachitsulo chosapanga dzimbiri ndikwabwino.Komabe, m'madera a m'mphepete mwa nyanja kapena pokhudzana ndi mankhwala ena a asidi ndi alkali, ayoni opangidwa ndi kloridi amatha kulowa mosavuta mufilimu yosapanga dzimbiri.Chitsulo chosapanga dzimbiri chidzawononga pang'onopang'ono ndi dzimbiri pakapita nthawi.Choncho, zitsulo zosapanga dzimbiri zimayenera kuchitidwa.Chitsulo chosapanga dzimbiri chimatha kukonza maziko odana ndi dzimbiri pofika zaka 3-8, kuchepetsa kwambiri mwayi wa dzimbiri lachitsulo chosapanga dzimbiri.

Ubwino wa Passivation

Pali maubwino ambiri opangira zitsulo zosapanga dzimbiri, zonse zomwe zimapangitsa kuti zigwire bwino ntchito komanso moyo wautali.

Kodi kuchita passivation-Stainless zitsulo?Tiuzeni.

Chifukwa mitundu yosiyanasiyana ya chitsulo chosapanga dzimbiri imagwiritsa ntchito mitundu yosiyanasiyana ya mankhwala ophatikizika, zina zimakhala zosiyana pakadutsa chitsulo chosapanga dzimbiri.Passivation imafuna chizolowezi.Komabe, njira yoyambira nthawi zambiri imakhala ndi masitepe omwewo: Onetsetsani kuti gawolo ndi loyera.Pokhapokha pamene gawo lapansi likuwonekera lingathe kuchitidwa bwino.Ikani mbali imodzi kapena zingapo kuti passivated mu chidebe.Thirani mankhwala amadzimadzi mumtsuko ndikusiya ziwalozo zilowerere kwa kanthawi.Sambani ndi madzi oyenda.Onetsetsani pamwamba pa mbali kutsukidwa popanda yotsalira passivation madzi pa.

Nitric acid passivationndi imodzi mwa matekinoloje apano a passivation.Tisanasankhe luso passivation, tiyenera kudziwa njira mankhwala chofunika kuti passivation anachita zitsulo zosapanga dzimbiri kupewa ntchito njira yolakwika kuwononga mbali.Ndipo nthawi yomweyo kusankha okhudzana passivation luso malinga ndi khalidwe la zitsulo zosapanga dzimbiri zosiyanasiyana.Mwachitsanzo, chromium yokhala ndi chitsulo chosapanga dzimbiri cha austenitic (monga 304 zitsulo zosapanga dzimbiri) nthawi zambiri imakhala yokwera kuposa ya chitsulo chosapanga dzimbiri cha martensitic (monga chitsulo chosapanga dzimbiri 430), zomwe zimapangitsa kuti ma alloys austenitic asamachite dzimbiri ndi pitting.

Pamaso passivation mbali zosapanga dzimbiri, mfundo zotsatirazi ziyenera kuganiziridwa:

Ma weldments sangakhale oyenera kungoyimitsa.Kanema wongokhala pamwamba pa chitsulo chosapanga dzimbiri amapangitsa kuti zisawonongeke.Kuwotcherera kwa Arc kumapangitsa kuti zinthuzo zikhale zocheperako pang'onopang'ono kutentha kwapang'onopang'ono, potero kuwononga kukana kwake kwa dzimbiri.
