Insimbi engagqwali iyinto emangalisayo edlala indima ebalulekile ezimbonini ezahlukene, ngenxa yezici zayo ezihlukile kanye nokusebenza okungenakuqhathaniswa. Kodwa bewazi ukuthi kukhona imfihlo efihliwe yokugcina ukusebenza kwayo nokuphila isikhathi eside? Le mfihlo isenkambisweni eyaziwa ngokuthi i-passivation.

Isingeniso Sensimbi Engagqwali

Ukuqonda amandla okungasebenzi kahle kuqala ngokuqonda izisekelo zensimbi engagqwali ngokwayo. Insimbi engagqwali akuyona nje into elula;

kuyingxube eyenziwe ngensimbi, ikhabhoni, kanye nenani elikhulu le-chromium.

Yini Eyenza Insimbi Engagqwali Ibe Yingqayizivele

Isidlali esiyinhloko endabeni yensimbi engagqwali yi-chromium. Uma itholakala emoyeni, i-chromium yakha ungqimba oluncane nolungabonakali lwe-chromium.

i-oxide ebusweni bensimbi. Lolu ungqimba alusebenzi, okusho ukuthi aluhlangani nanoma yini enye.

1. Ukuqonda Ukumelana Nokugqwala

I-Chromium oxide iyingelosi evikela insimbi engagqwali. Ivimbela ukugqwala nokugqwala, okuyizingibe ezivamile zezinye izinsimbi eziningi.

Lokhu kumelana nokugqwala kwenza insimbi engagqwali ibizwe futhi isetshenziswe kabanzi.

2. Indima Yokuthukuthela Ensimbini Engagqwali

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

Lokhu kwenza insimbi imelane kakhulu nokugqwala nokugqwala.

3. Isayensi Ebangela Ukungabi Nandaba

Ngesikhathi sokuphumula, insimbi engagqwali iphathwa ngesisombululo se-asidi emnene. Lokhu kususa insimbi yamahhala kanye nezinye izinto ezingcolisayo ebusweni,

okungase kuphazamise ukwakheka kwengqimba ye-chromium oxide.

Ungathanda ukwazi ukuthi kungani insimbi engagqwali idinga ukungasebenzi?

Ekuqaleni, sidinga ukwazi ukuthi kusho ukuthini insimbi engagqwali ne-passivation? Ukudlula kwensimbi engagqwali kubhekisela ekwenzeni ubuso bensimbi engagqwali busabelane ne-passivation agent ukuze kwakheke ifilimu eqinile yokudlula evikela i-substrate yensimbi engagqwali ekugqwaleni okubangelwa yi-oxidation kanye nokugqwala. Ukusebenza kokumelana nokugqwala kwensimbi engagqwali kuhle kakhulu. Kodwa-ke, ezindaweni ezisogwini noma lapho kuthintana namakhemikhali athile e-acid kanye ne-alkali, ama-ion e-chloride akhiqizwayo angangena kalula kwifilimu engasebenzi yensimbi engagqwali. Insimbi engagqwali izogqwala kancane kancane futhi igqwale ngokuhamba kwesikhathi. Ngakho-ke, insimbi engagqwali idinga ukudlula. Insimbi engagqwali engagqwali ingathuthukisa isisekelo sokuqala sokulwa nokugqwala ngeminyaka engu-3-8, kunciphisa kakhulu amathuba okugqwala kwensimbi engagqwali.

Isici sesihlungi sensimbi engagqwali se-HENGKO sinosayizi oqondile wembobo yomoya, usayizi wembobo yesihlungi esifanayo kanye nokusatshalaliswa okufanayo; ukungena komoya okuhle, ukujikeleza okusheshayo, umphumela omuhle wokubanjwa, ukusebenza kahle kokuhlunga okuphezulu; ukumelana okuhle kokugqwala, ukumelana nokushisa okuphezulu, ukumelana nokushaqeka kokushisa, izinto zensimbi engagqwali zingaba yi-600 Ukusebenza ekushiseni okuphezulu; ubude beshubhu lesihlungi esincane bungafinyelela ku-800mm, usayizi omkhulu wesakhiwo sepuleti lesihlungi ungafinyelela ku-800mm ubude * ububanzi obungu-450mm, kanti ububanzi obukhulu besakhiwo sesihlungi esiyindilinga bungafinyelela ku-450mm. Siphinde sinikeze ukudlula kwezingxenye zomkhiqizo, Uma udinga ukufaka endaweni eqinile yokumelana nokugqwala kanye nokumelana nokugqwala.

Izinzuzo Zokudlula Emsebenzini

Kunezinzuzo eziningi zokusebenzisa insimbi engagqwali ngendlela ethambile, zonke ezifaka isandla ekusebenzeni kwayo okuthuthukisiwe kanye nobude bayo.

Ungayenza kanjani insimbi engagqwali ye-passivation?Ake sikutshele.

Ngenxa yokuthi izinhlobo ezahlukene zensimbi engagqwali zisebenzisa inhlanganisela ehlukene yamakhemikhali okudlulisa, eminye imininingwane izohluka ngesikhathi senqubo yokudlulisa yensimbi engagqwali. Ukudlulisa kudingeka kwenziwe ngokwezifiso. Kodwa-ke, inqubo eyisisekelo ivame ukuba nezinyathelo ezifanayo: Qinisekisa ukuthi ubuso bengxenye buhlanzekile. Kuphela uma isisekelo sidaluliwe lapho singasuswa khona kangcono. Faka ingxenye eyodwa noma eziningana ukuze zifakwe esitsheni. Thela uketshezi lwamakhemikhali esitsheni bese uvumela izingxenye zicwiliswe isikhathi esithile. Geza ngamanzi agobhozayo. Qinisekisa ukuthi ubuso bengxenye buhlanziwe futhi ngaphandle koketshezi olusele lokudlulisa.

Ukudlula kwe-asidi ye-nitricingenye yezindlela zobuchwepheshe eziyisisekelo zamanje zokudlulisa amandla. Ngaphambi kokukhetha ubuchwepheshe bokudlulisa amandla, sidinga ukwazi ikhambi lamakhemikhali elidingekayo ukuze kuphendulwe insimbi engagqwali ukuze sigweme ukusebenzisa ikhambi elingalungile ukuze kubangele umonakalo ezingxenyeni. Futhi ngesikhathi esifanayo sikhetha ubuchwepheshe bokudlulisa amandla obuhlobene ngokwesimo sensimbi engagqwali ehlukene. Isibonelo, okuqukethwe kwe-chromium kwensimbi engagqwali ye-austenitic (njengensimbi engagqwali engu-304) kuvame ukuba phezulu kunokwensimbi engagqwali ye-martensitic (njengensimbi engagqwali engu-430), okwenza ama-alloy e-austenitic amelane kakhulu nokugqwala kanye nomgodi.

Ngaphambi kokufaka izingxenye zensimbi engagqwali, amaphuzu alandelayo kufanele acatshangelwe:

Ukushisela kungase kungafaneleki ukushisela. Ifilimu engasebenzi ebusweni bensimbi engagqwali yenza ukuthi imelane nokugqwala. Ukushisela kwe-arc kuzokwenza izinto zihlale isikhathi esifushane sokujikeleza kokushisa okuphezulu, ngaleyo ndlela kubhubhise ukumelana kwazo nokugqwala.

Kudingeka ukugeza ngamakhemikhali ngokwezifiso. Izinga lokushisa kanye nohlobo lwe-asidi olusetshenziswa enqubweni yokudlulisa kumele kulungiswe ngokuya nge-alloy engasebenzi. Lokhu kwengeza izindleko kanye nobunzima uma kuqhathaniswa nokupholisha nge-electro. Amanye ama-alloy awakwazi ukungasebenzi. Isibonelo, amanye ama-alloy ensimbi engagqwali anokuqukethwe okuphansi kwe-chromium kanye ne-nickel azobhujiswa. Ngakho-ke, awakwazi ukungasebenzi.

Inzuzo eyinhloko yokwenziwa kwe-stainless steel passivation ukuthi kungathuthukisa ukumelana nokugqwala kwezingxenye zensimbi engagqwali, futhi izindleko ziphansi kunezokwenziwa kwe-electropolishing. Inkinga enkulu yenqubo yokwenziwa kwe-electropolishing ukuthi ibiza kakhulu kunenqubo ejwayelekile yokwenziwa kwe-passivation. Ngaphezu kwalokho, ukwenziwa kwe-electropolishing akunawo umthelela omkhulu ongqimbeni lwe-oxide oluvikelayo lwensimbi njengokwenziwa kwe-passivation.

Kodwa-ke, uma kukhulunywa ngesimo sobuso bezingxenye njengento ebaluleke kakhulu, ukupholisha nge-electro kuseyindlela ekhethwayo yokwelapha. Ukupholisha nge-electro akufani nokupholisha nge-electro ukuze wenze ubuso bengxenye bube bushelelezi, futhi akushintshi kakhulu ukubukeka kwengxenye. Ngakho-ke, ukupholisha nge-passivation akuyona indlela efanelekile uma umkhiqizo udinga ubuso obubushelelezi nobungenamatheli. Izimboni zokudla nezokwelapha zivame ukusebenzisa izindawo zensimbi engagqwali ezipholishwe nge-electro ngoba ubuso bubushelelezi futhi kulula ukuhlanza nokubulala amagciwane.
