Insimbi engagqwali iyinto engakholeki edlala indima ebalulekile ezimbonini ezahlukahlukene, ngenxa yezimpawu zayo ezihlukile nokusebenza okungenakuqhathaniswa.Kodwa bewazi yini ukuthi kunemfihlo efihliwe yokugcina ukusebenza kwayo nokuphila isikhathi eside?Le mfihlo ilele enqubweni eyaziwa ngokuthi i-passivation.

Isingeniso Sensimbi Engagqwali

Ukuqonda amandla e-passivation kuqala ngokwazisa izisekelo zensimbi engagqwali ngokwayo.Insimbi engagqwali ayiyona nje into elula;

iyingxubevange eyenziwe ngensimbi, ikhabhoni, kanye nomthamo omkhulu we-chromium.

Yini Eyenza Insimbi Engagqwali Ihluke

Umdlali oyinhloko endabeni yensimbi engagqwali i-chromium.Lapho ichayeke kumoya-mpilo, i-chromium yenza ungqimba oluncane olungabonakali lwe-chromium

i-oxide ebusweni bensimbi.Lesi sendlalelo asisebenzi, okusho ukuthi asisabeli nanoma yini enye.

1. Ukuqonda Ukumelana Nokugqwala

I-Chromium oxide iyingelosi eqaphile yensimbi engagqwali.Ivimbela ukugqwala nokugqwala, okuyizingibe ezivamile kwezinye izinsimbi.

Lokhu kumelana nokugqwala kunikeza insimbi engagqwali igama layo kanye nokusetshenziswa kwayo kabanzi.

2. Iqhaza Le-Passivation Ensimbi Engagqwali

Manje, ake singene esihlokweni esiyinhloko - i-passivation.I-Passivation inqubo yamakhemikhali ethuthukisa ungqimba lwe-chromium oxide eyenzeka ngokwemvelo.

Lokhu kwenza insimbi imelane nakakhulu nokugqwala nokugqwala.

3. Isayensi Engemuva Kokuthakasela

Ngesikhathi se-passivation, insimbi engagqwali iphathwa ngesisombululo se-asidi esincane.Lokhu kususa i-iron yamahhala nokunye ukungcola ebusweni,

okungase kuphazamise ukwakheka kongqimba lwe-chromium oxide.

Ungathanda ukwazi ukuthi kungani insimbi engagqwali idinga ukudlula?

Ekuqaleni, sidinga ukwazi ukuthi iyini incazelo yensimbi engagqwali? okubangelwa i-oxidation nokugqwala.Ukusebenza kokumelana nokugqwala kwensimbi engagqwali kuhle kakhulu.Kodwa-ke, ezindaweni ezisogwini noma lapho kuthintana namakhemikhali athile e-asidi ne-alkali, ama-ion e-chloride akhiqiziwe angangena kalula efilimini yensimbi engagqwali.Insimbi engagqwali kancane kancane izogqwala futhi igqwale ngokuhamba kwesikhathi.Ngakho-ke, insimbi engagqwali idinga ukudlula.Insimbi engagqwali engagqwali ingathuthukisa isisekelo sokuqala se-anti-rust ngeminyaka engu-3-8, yehlise kakhulu ithuba lokugqwala kwensimbi engagqwali.

Isici sokuhlunga sensimbi engenasici ye-HENGKO inosayizi oqondile wembotshana yomoya, usayizi wembobo yesihlungi esifanayo nokusabalalisa okufanayo;ukungena komoya okuhle, ukujikeleza okusheshayo, umphumela omuhle wokungenela, ukusebenza kahle kokuhlunga okuphezulu;ukumelana nokugqwala okuhle, ukumelana nokushisa okuphezulu, ukumelana nokushaqeka kokushisa, impahla yensimbi engagqwali ingaba 600 Ukusebenza ekushiseni okuphezulu;ubude beshubhu elihle lokuhlunga bungafinyelela ku-800mm, ubukhulu obukhulu besakhiwo sepuleti lokuhlunga bungafinyelela ubude obungu-800mm * 450mm ububanzi, futhi ububanzi obukhulu besakhiwo sokuhlunga esiyindilinga bungafinyelela ku-450mm.Siphinde futhi sinikeze ukudlula kwezingxenye zomkhiqizo, Uma udinga ukufaka isicelo sokumelana nokugqwala okuqinile kanye nemvelo yokumelana nokugqwala.

Izinzuzo Passivation

Kunezinzuzo eziningi zokudlula insimbi engagqwali, konke okunomthelela ekusebenzeni okuthuthukisiwe nokuphila isikhathi eside.

Indlela yokwenza i-passivation-stainless steel?Ake sikutshele.

Ngenxa yokuthi izinhlobo ezihlukene zensimbi engagqwali zisebenzisa inhlanganisela ehlukene yamakhemikhali e-passivation, eminye imininingwane izohluka ngesikhathi senqubo yokudlulisa insimbi engagqwali.Passivation idinga ngokwezifiso.Nokho, inqubo eyisisekelo ivame ukuba nezinyathelo ezifanayo: Qinisekisa ukuthi ingaphezulu lengxenye lihlanzekile.Kuphela uma i-substrate ibonakalisiwe lapho ingadlula khona kangcono.Faka ingxenye eyodwa noma ezimbalwa ezizodluliswa esitsheni.Thela uketshezi lwamakhemikhali esitsheni bese uvumela izingxenye zicwilise isikhathi esithile.Geza ngamanzi agobhozayo.Qinisekisa ukuthi ingaphezulu lengxenye ehlanziwe futhi ngaphandle koketshezi lwe-passivation olusalile luvuliwe.

I-nitric acid passivationingenye yobuchwepheshe bamanje bokudlula.Ngaphambi kokukhetha ubuchwepheshe be-passivation, sidinga ukwazi isixazululo samakhemikhali esidingekayo ekuphenduleni kwe-passivation yensimbi engagqwali ukuze sigweme ukusebenzisa isisombululo esingalungile ukudala umonakalo ezingxenyeni.Futhi ngesikhathi esifanayo ukukhetha ubuchwepheshe bokudlula obuhlobene ngokusho kwesici sensimbi engagqwali ehlukene.Isibonelo, okuqukethwe kwe-chromium kwensimbi engagqwali ye-austenitic (njengensimbi engu-304) kuvame ukuba phezulu kunaleyo yensimbi engagqwali ye-martensitic (njengensimbi engagqwali engu-430), okwenza ama-alloy e-austenitic amelane kakhulu nokugqwala nokubhoboza.

Ngaphambi kokudlula izingxenye zensimbi engagqwali, amaphuzu alandelayo kufanele acatshangelwe:

Ama-weldments angahle angafaneleki ukwenziwa.Ifilimu yokwenziwa engaphezulu kwensimbi engagqwali iyenza imelane nokugqwala.I-arc welding izobeka impahla esikhathini esifushane sokushisa okushisayo kwamabhayisikili, ngaleyo ndlela kucekele phansi ukumelana nokugqwala kwayo.

Kudingeka ukugeza kwamakhemikhali okungokwezifiso.Izinga lokushisa kanye nohlobo lwe-asidi esetshenziswa enqubweni yokudlula kufanele kulungiswe ngokuya ngengxubevange edluliswayo.Lokhu kungeza izindleko nobunzima uma kuqhathaniswa ne-electropolishing.Amanye ama-alloys awakwazi ukuqedwa.Isibonelo, amanye ama-alloys ensimbi engagqwali ane-chromium ephansi nokuqukethwe kwe-nickel azocekelwa phansi.Ngakho-ke, azikwazi ukuguqulwa.

Inzuzo eyinhloko ye-stainless steel passivation ukuthi ingathuthukisa ukumelana nokugqwala kwezingxenye zensimbi engagqwali, futhi izindleko ziphansi kunezo ze-electropolishing.Ububi obukhulu benqubo ye-electropolishing ukuthi ibiza kakhulu kunenqubo evamile yokudlula.Ngaphezu kwalokho, i-electropolishing ayinawo umthelela obalulekile ongqimbeni lwensimbi oluvikelayo njenge-passivation.

Kodwa-ke, lapho ukhuluma ngesimo sobuso sezingxenye ekucatshangelweni okuyinhloko, i-electropolishing kusewukwelashwa okuthandwayo.I-passivation ayifani ne-electropolishing ukwenza ubuso bengxenye bushelelezi, futhi akuguquli kakhulu ukubukeka kwengxenye.Ngakho-ke, i-passivation akuyona indlela ekahle uma umkhiqizo udinga indawo ebushelelezi futhi enganamathele.Izimboni zokudla kanye nemithi zivame ukusebenzisa izindawo zensimbi engagqwali epholishwe nge-electro ngoba indawo engaphezulu ibushelelezi futhi kulula ukuyihlanza futhi ibulale amagciwane.
