Indlela Yokusebenzisa I-Pasivate Stainless

Intsimbi engagqwaliyo yaziwa kakhulu ngokumelana kwayo nokugqwala, amandla, kunye nokuhlala ixesha elide. Kodwa kwanentsimbi engagqwaliyo yodidi oluphezulu ingazuza kunyango lomphezulu olubizwa ngokuba yiukungasebenzi kakuhleUkuba uyazibuzaindlela yokususa i-stainless stainless, eli nqaku liza kukubonisa yonke into ekufuneka uyazi—ukususela ekubeni yintoni na into yokungakhathali, ukuya ekubeni kutheni ibalulekile, kunye nemiyalelo elandelelanayo yendlela yokwenza ngokuchanekileyo.

Esi sikhokelo siziswe kuwe ngui-sakysteel, umthengisi othembekileyo wehlabathi weemveliso zentsimbi engagqwaliyo, obonelela ngenkxaso yobugcisa kunye nezixhobo zexabiso eliphezulu kumashishini kwihlabathi liphela.

Yintoni iPassivation?

Ukunyamezelayinkqubo yeekhemikhali esusa isinyithi esikhululekileyo kunye nezinye izinto ezingcolisayo kumphezulu wentsimbi engagqwaliyo kwaye ikhuthaza ukwakheka komaleko we-oxide obhityileyo nokhuselayo. Olu maleko we-oxide—ngokuyintloko i-chromium oxide—lusebenza njengesikhuselo ekulweni nokugqwala kunye nokugqwala.

Nangona intsimbi engagqwaliyo ngokwemvelo idala olu maleko xa luvezwa emoyeni, inkqubo yokuyithambisa iyayiphucula kwaye iyizinzise, ​​ingakumbi emva kweenkqubo zokuvelisa ezifana nokulungisa, ukuwelda, ukugaya, okanye ukulungisa ubushushu.

Kutheni ukungabi namdla kubalulekile

Ukuhambisa umoya ngaphandle kwento ayilonyathelo nje lokuzikhethela—kubalulekile kumashishini amaninzi afuna imigangatho ephezulu yokucoceka, ukumelana nokugqwala, kunye nokuqina.

Iingenelo zokusebenzisa intsimbi engagqwaliyo ngaphandle kokuyithulula ziquka:

• Ukumelana nokugqwala okuphuculweyo

• Ukususwa kwamasuntswana esinyithi afakwe ngaphakathi

• Ukususwa kongcoliseko lomphezulu

• Inkangeleko yomphezulu ephuculweyo

• Ubomi benkonzo obude kwiindawo ezinzima

i-sakysteelicebisa ukungasebenzi kakuhle kwezixhobo ezingenasici ezisetyenziswa kwimizi-mveliso yolwandle, yamayeza, eyodidi lokutya, kunye neyokucubungula iikhemikhali.

Ufanele Usebenzise Nini Intsimbi Engagqwaliyo?

Ukudlulisa umbane kufuneka kuqwalaselwe emva kwayo nayiphi na inkqubo enokuveza okanye ingcolise umphezulu wentsimbi engagqwaliyo:

• Umatshini okanye ukusika

• Ukuwelda okanye ukurhawuzelela

• Ukuqhotsa okanye ukususa iikalika

• Ukusila okanye ukupolisha

• Ukuphatha ngezixhobo zentsimbi yekhabhoni

• Ukuvezwa kwizinto ezingcolisayo okanye kwiindawo ezingqonge i-chloride

Ukuba iindawo zakho ezingenasici zibonisa iimpawu zokutshintsha kombala, ungcoliseko, okanye ukuncipha kokumelana nokugqwala, lixesha lokuqwalasela ukungasebenzi kakuhle.

Ngawaphi amaBanga eNtsimbi Engagqwaliyo Anokungafakwa?

Uninzi lweeklasi zentsimbi engenasici zinokungafakwa kwi-passivative, kodwa iziphumo zingahluka ngokusekwe kwi-alloy.

i-sakysteelIbonelela ngesikhokelo sokukhetha izinto ezisetyenziswayo ukunceda abathengi bakhethe amanqanaba angenazintsimbi angasebenzi kakuhle kwaye asebenze ngokuthembekileyo kwiindawo ezinobungozi.

Indlela Yokwenza Intsimbi Engagqwaliyo Ingasebenzi: Inkqubo Yenyathelo Ngenyathelo

Kukho iintlobo ezimbini eziphambili zeearhente zokudlulisa amandla ezisetyenziswa kushishino:

• Isekelwe kwi-asidi ye-nitricizisombululo

• Isekelwe kwi-citric acidizisombululo (ezinobuhlobo nokusingqongileyo)

Nantsi ingqikelelo ngokubanzi yenkqubo yokudlulisa ingqondo:

Inyathelo 1: Coca umphezulu

Ukucoca ngokucokisekileyo kubalulekile ngaphambi kokuba kusetyenziswe i-passivation. Naluphi na uthuli, ioyile, igrisi, okanye intsalela inokuphazamisana ne-chemical reaction.

Iindlela zokucoca ziquka:

• Izinto zokucoca i-alkaline

• Izihluzi

• Izisombululo zokucoca

• Ukucoca nge-ultrasonic (kwiindawo ezincinci)

Hlamba ngamanzi acocekileyo uze womise ukuba kuyimfuneko.

Inyathelo lesi-2: Susa isikali okanye iPickle (Ukuba iyafuneka)

Ukuba umphezulu wentsimbi engagqwaliyo unomlinganiselo omkhulu, ii-oxide ze-weld, okanye ukutshintsha kombala, yenzaukukhainkqubo ngaphambi kokuba umntu ayeke.

Ukususa i-pickling:

• Iileya ze-oxide

• Ukutshintsha kombala we-weld

• Umbala wobushushu

Ukugalela i-pickling kudla ngokusetyenziswa i-asidi enamandla njenge-nitric-hydrofluoric acid okanye i-pickling paste. Emva kokugalela i-pickling, hlambulula kakuhle ngaphambi kokuba uqhubeke nokukhupha i-passivation.

Inyathelo lesi-3: Sebenzisa isisombululo sokungakhathali

Faka inxalenye ecociweyo kwindawo yokuhlamba okanye uyisebenzise ngesandla.

Indlela ye-asidi ye-nitric:

• Uxinzelelo: 20–25% i-nitric acid

• Ubushushu: 50–70°C

• Ixesha: imizuzu engama-20–30

Indlela ye-citric acid:

• Uxinaniso: 4–10% i-citric acid

• Ubushushu: 40–60°C

• Ixesha: imizuzu engama-30–60

Soloko usebenzisaizikhongozeli zeplastiki okanye zentsimbi engagqwaliyoukuze kuthintelwe ukungcola ngexesha lokuntywiliselwa emanzini.

Inyathelo lesi-4: Hlamba kakuhle

Emva kwexesha elifunekayo kwibhafu yokuthambisa umzimba, hlambulula loo ndawo ngeamanzi acocekileyo okanye anyibilikisiweyoAmanzi ompompo anokushiya iiminerali okanye ukungcola.

Qinisekisa ukuba zonke iintsalela ze-asidi zisusiwe ngokupheleleyo.

Inyathelo lesi-5: Yomisa umphezulu

Yomisa usebenzisa umoya ocinezelweyo okanye amalaphu acocekileyo. Kuphephe ukungcoliswa zizixhobo zentsimbi yekhabhoni okanye amalaphu angcolileyo.

Kwizicelo ezibalulekileyo (umz., amayeza okanye ezonyango), iinxalenye zingomiswa kwigumbi elicocekileyo okanye kwigumbi lokungena.

Ukhetho: Vavanya umphezulu

Iindawo ezingasetyenziswanga zingavavanywa kusetyenziswa:

• Uvavanyo lweCopper sulfate(ASTM A967): Ifumanisa isinyithi sasimahla

• Uvavanyo lwegumbi elinomswakama ophezulu: Iveza iindawo kwiindawo ezimanzi ukuze ijonge ukumelana nokugqwala

• Uvavanyo lokuntywiliselwa emanzini okanye lokutshizwa ngetyuwa: Ukuze ufumane uvavanyo oluphezulu lokusebenza kokugqwala

i-sakysteelisebenzisa imigangatho ye-ASTM A967 kunye ne-A380 ukuqinisekisa umgangatho wokungangenisi umoya kunye nokuqinisekisa ukhuseleko olufanelekileyo lokugqwala.

Iingcebiso zoKhuseleko zokuPhumla

• Nxiba izixhobo zokuzikhusela rhoqo: iiglavu, iiglasi zeglasi, i-apron

• Sebenza kwindawo enomoya ococekileyo

• Nciphisa kwaye ulahle ii-asidi ngokwemigaqo yendawo

• Kuphephe ukusebenzisa iibhrashi zentsimbi okanye izixhobo ezinokubuyisela ukungcola

• Gcina iindawo ezingasebenziyo kwindawo ecocekileyo neyomileyo

Izicelo Ezifuna Intsimbi Engagqwaliyo Engafakwanga

Ukudlulisa i-passivation kubalulekile kwizinto ezisetyenziswa kwi:

• Izixhobo zokulungisa ukutya neziselo

• Oomatshini bezonyango kunye namayeza

• Izakhiwo zeenqwelo-moya kunye neenqwelo-moya

• Izityalo zeekhemikhali kunye neekhemikhali

• Ukuveliswa kwee-semiconductor

• Ukufakelwa kwezixhobo zaselwandle nezaselwandle

i-sakysteelIbonelela ngeemveliso zentsimbi engagqwaliyo ezilungele ukutyibilika kuzo zonke ezi zicelo zingasentla, ixhaswa kukulandeleka kwezinto kunye neziqinisekiso zomgangatho.

Ezinye iindlela kunye nonyango oluhambelanayo nomphezulu

Ukongeza kwi-passivation, ezinye iiprojekthi zingazuza kwezi:

• Ukupholisha ngombane:Isusa umaleko womphezulu obhityileyo ukuze kugqitywe kakuhle kwaye kube bushelelezi

• Ukupholisha ngoomatshini:Yandisa ukukhanya komphezulu kwaye isusa ungcoliseko

• Ukukha:Inamandla kune-passivation, isetyenziselwa ukucoca ii-welds kunye ne-scaling

• Iingubo zokukhusela:I-Epoxy, iTeflon, okanye iingubo zeseramikhi ukuze zihlale ixesha elide

Nxibelelanai-sakysteelukuze kuchongwe eyona ndlela ilungileyo yokulungisa emva kokwenziwa kwento engayi kuyenza xa uyisebenzisa.

Isiphelo: Indlela Yokusebenzisa Intsimbi Engagqwaliyo Ukuze Usebenze Kakhulu

Ukukhupha izinto ezingafunekiyo yinkqubo ebalulekileyo yokugqiba ephucula ukumelana nokugqwala kwentsimbi engagqwaliyo ngokucoca ngeekhemikhali nokubuyisela umaleko wayo okhuselayo we-chromium oxide. Nokuba usebenza kwishishini lokutya, kwimveliso yamayeza, okanye kwimveliso yaselwandle, ukususa izinto ezingafunekiyo kwintsimbi engagqwaliyo kuqinisekisa ukuba zisebenza kakuhle kwiindawo ezinzima.

Ngokucocwa kakuhle, ukuntywiliselwa, ukuhlamba, kunye nokuvavanywa, intsimbi engagqwaliyo inokufikelela kwisakhono sayo esipheleleyo sokuqina kunye nokumelana nomhlwa. Kwaye ngenkxaso yomthengisi othembekileyo onjei-sakysteel, ungaqinisekisa ukuba izinto zakho ezingenasici zicutshungulwe kakuhle kwaye zilungele ukulungiswa.
