Ibyuma bitagira umwanda ni ibintu bidasanzwe bigira uruhare runini mu nganda zinyuranye, bitewe n'imiterere yihariye n'imikorere idasanzwe. Ariko wari uzi ko hari ibanga ryihishe ryo gukomeza imikorere no kuramba? Iri banga riri mubikorwa bizwi nka passivation.

Intangiriro Kumashanyarazi

Gusobanukirwa imbaraga za passivation bitangirana no gushima ishingiro ryibyuma ubwabyo. Ibyuma bidafite ingese ntabwo ari ibintu byoroshye gusa;

ni amavuta akozwe mu byuma, karubone, hamwe na chromium nyinshi.

Niki Cyuma Icyuma kidasanzwe

Umukinyi wingenzi mumateka yicyuma ni chromium. Iyo ihuye na ogisijeni, chromium ikora urwego ruto, rutagaragara rwa chromium

oxyde hejuru yicyuma. Uru rupapuro ni pasiporo, bivuze ko rutitabira ikindi kintu cyose.

1. Gusobanukirwa Kurwanya Ruswa

Chromium oxide numumarayika murinzi wibyuma bitagira umwanda. Irinda ingese no kwangirika, ibyo bikaba ari imitego isanzwe yandi mabuye.

Uku kurwanya ruswa itanga ibyuma bitagira umwanda izina ryayo nikoreshwa ryayo.

2. Uruhare rwa Passivation mubyuma bitagira umwanda

Noneho, reka twibire mumutwe wingenzi - passivation. Passivation ninzira yimiti yongerera imbaraga chromium oxyde igaragara.

Ibi bituma ibyuma birwanya cyane ingese no kwangirika.

3. Siyanse Yihishe inyuma ya Passivation

Mugihe cya passivation, ibyuma bidafite ingese bivurwa numuti woroshye wa acide. Ibi bikuraho ibyuma byubusa nibindi byanduza hejuru,

zishobora guhungabanya imiterere ya chromium oxyde.

Urashaka kumenya impamvu ibyuma bitagira umwanda bigomba gutambuka?

Ubwa mbere, dukeneye kumenya icyo insobanuro yicyuma cya passivation-idafite ingese pass Passivation yicyuma kitagira umwanda bivuga gukora hejuru yicyuma kitagira umwanda gikora hamwe na passiyo kugirango ikore firime ihamye irinda insimburangingo ibyuma bitagira ingese. biterwa na okiside na ruswa. Imikorere yo kurwanya ingese yicyuma ni nziza. Nyamara, mu turere two ku nkombe cyangwa duhuye na aside hamwe n’imiti ya alkali, ion ya chloride yakozwe irashobora kwinjira byoroshye muri firime ya pasiporo yicyuma. Ibyuma bitagira umwanda bizagenda byangirika buhoro buhoro. Kubwibyo, ibyuma bidafite ingese bigomba kuba byoroshye. Ibyuma bitagira umuyonga birashobora guteza imbere umusingi wambere wo kurwanya ingese mu myaka 3-8, bikagabanya cyane amahirwe yo kutagira ingese.

HENGKO ibyuma bitagira umuyonga byungurujwe byungurura bifite ubunini bwuzuye bwimyuka yo mu kirere, ubunini bwa filteri imwe hamwe no gukwirakwiza kimwe; umwuka mwiza uhumeka, kuzenguruka byihuse, ingaruka nziza yo gufata intera, gukora neza cyane; Kurwanya ruswa neza, kurwanya ubushyuhe bwo hejuru, kurwanya ubushyuhe, ibikoresho byuma bitagira umwanda birashobora kuba 600 Gukora mubushyuhe bwinshi; uburebure bwumuyoboro mwiza wo gushungura bushobora kugera kuri 800mm, ubunini ntarengwa bwububiko bwa plaque burashobora kugera kuri 800mm z'uburebure * 450mm z'ubugari, kandi diameter ntarengwa yimiterere ya filteri irashobora kugera kuri 450mm. Dutanga kandi passivation yibice byibicuruzwa, Niba ukeneye gukoresha muburyo bukomeye bwo kurwanya ruswa hamwe n’ibidukikije birwanya ingese.

Inyungu za Passivation

Hariho inyungu nyinshi zo gutambutsa ibyuma bidafite ingese, byose bigira uruhare mubikorwa byayo byongerewe no kuramba.

Nigute ushobora gukora passivation-idafite ibyuma?Reka tubabwire.

Kuberako ubwoko butandukanye bwibyuma bitagira umwanda bukoresha uburyo butandukanye bwimiti ya passivation, amakuru amwe azaba atandukanye mugihe cyo gutambuka kwicyuma. Passivation ikeneye kumenyera. Nyamara, inzira yibanze akenshi ifite intambwe imwe: Menya neza ko ubuso bwigice gifite isuku. Gusa iyo substrate yerekanwe irashobora kuba nziza passivatif. Shira igice kimwe cyangwa byinshi kugirango uhindurwe mubintu. Suka amazi ya chimique muri kontineri hanyuma ureke ibice bimare mugihe runaka. Karaba n'amazi atemba. Menya neza ko igice cyigice gisukuye kandi kidafite amazi asigaranye.

Nitric aside passivationni bumwe muburyo bwa tekinoroji ya passivation. Mbere yo guhitamo tekinoroji ya passivation, dukeneye kumenya igisubizo cyimiti ikenewe kugirango passivation reaction yicyuma kitagira umwanda kugirango twirinde gukoresha igisubizo kibi kugirango cyangize ibice. Kandi icyarimwe, guhitamo tekinoroji ijyanye na passivation ukurikije ibiranga ibyuma bitandukanye. Kurugero, chromium yibigize ibyuma bya austenitike (nka 304 ibyuma bitagira umuyonga) akenshi iba hejuru kurenza iy'icyuma cya martensitike (nk'ibyuma 430 bitagira umuyonga), bigatuma amavuta ya austenitike arwanya ruswa no gutobora.

Mbere yo gutambuka ibyuma bitagira umwanda, ingingo zikurikira zigomba gutekerezwa:

Gusudira ntibishobora kuba bibereye passivation. Filime ya pasiporo hejuru yicyuma kitagira umwanda ituma ruswa idashobora kwangirika. Gusudira kwa Arc bizashyira ibikoresho mugihe gito cyubushyuhe bwo hejuru bwumuriro wamagare, bityo bikangiza kwangirika kwayo.

Birakenewe kwiyuhagira imiti. Ubushyuhe n'ubwoko bwa aside ikoreshwa mugikorwa cya passivation igomba guhinduka ukurikije ibivangwa na passivat. Ibi byongera ibiciro kandi bigoye ugereranije na electropolishing. Amavuta amwe amwe ntashobora gutwarwa. Kurugero, ibyuma bimwe bidafite ingese hamwe na chromium nkeya hamwe na nikel bizasenywa. Kubwibyo, ntibishobora gutwarwa.

Inyungu nyamukuru yo gutwarwa nicyuma ni uko ishobora guteza imbere kurwanya ingese yibyuma, kandi igiciro kiri munsi yicy'amashanyarazi. Ikibazo gikomeye cyibikorwa bya electropolishinge nuko bihenze kuruta inzira ya passivation isanzwe. Byongeye kandi, amashanyarazi ntabwo agira ingaruka zikomeye kurwego rwo gukingira okiside irinda ibyuma nka passivation.

Ariko, iyo uvuze hejuru yubuso bwibice mubitekerezo byingenzi, amashanyarazi aracyariwo muti watoranijwe. Passivation ntabwo isa na electropolishinge kugirango ubuso bwigice bugende neza, nabwo ntabwo bihindura cyane isura yigice. Kubwibyo, passivation ntabwo aruburyo bwiza niba ibicuruzwa bikeneye ubuso bworoshye kandi butari inkoni. Inganda zikora ibiryo na farumasi zikunda gukoresha amashanyarazi asize amashanyarazi hejuru yicyuma kuko ubuso bworoshye kandi bworoshye gusukura no kwanduza.
