Kuthetha ukuthini ukudlula kwentsimbi engagqwaliyo?

Intsimbi engagqwaliyo ixatyiswa kakhulu ngenxa yokumelana kwayo nokugqwala kunye nenkangeleko yayo ecocekileyo neyanamhlanje. Kodwa kwanale nto ihlala ixesha elide ixhamla kunyango olongezelelweyo lokuphucula ukumelana kwayo nokugqwala - inkqubo eyaziwa ngokuba yiukungasebenzi kakuhleOlu nyango lweekhemikhali ludlala indima ebalulekileyo ekwandiseni ixesha elide kunye nokusebenza kwentsimbi engagqwaliyo kumashishini onke.

Kweli nqaku, sichaza ukuba yintoni i-passivation, indlela esebenza ngayo, isizathu sokuba ibaluleke, kunye nokuba isetyenziswa phi rhoqo. Njengomthengisi ophambili wentsimbi engagqwaliyo,i-sakysteelIbonelela ngeemveliso zentsimbi engagqwaliyo ezingasetyenziswanga kunye nezingasetyenziswanga ezenziwe ngokwemigangatho yehlabathi.

Yintoni iPassivation

I-Passivation yinkqubo yeekhemikhali esusa i-iron ekhululekileyo kunye nezinye izinto ezingcolisayo kumphezulu kwintsimbi engagqwaliyo. Emva kokucoca, isinyithi siphathwa nge-oxidant ethambileyo, edla ngokuba yi-nitric acid okanye i-citric acid, ukukhuthaza ukwakheka komaleko we-oxide obhityileyo, ocacileyo phezu komphezulu.

Olu maleko lukhusela kakhulu ukuxhathisa kwesinyithi kumhlwa kunye nokugqwala ngokuthintela iindawo ezisebenzayo ezikhokelela kwiimpembelelo zeekhemikhali kwindalo esingqongileyo.

I-Passivation ayisiyonto yokugquma okanye yokugquma. Endaweni yoko, iphucula iipropati zendalo zokukhusela zentsimbi engagqwali ngokuvumela umxholo wayo we-chromium ukuba wenze umaleko we-oxide ozinzileyo.

Indlela iPassivation Esebenza Ngayo

Inkqubo idla ngokubandakanya amanyathelo amathathu aphambili:

1. Ukucoca
   Zonke iioyile, amafutha, kunye nenkunkuma kufuneka zisuswe kusetyenziswa izicoci ze-alkaline okanye ezisekelwe kwisinyibilikisi. Oku kuqinisekisa ukuba i-acid bath inokuchukumisa umphezulu wesinyithi ongenanto.

2. Unyango lwe-Acid Bath
   Intsimbi engagqwaliyo emva koko ifakwa kwisisombululo se-asidi esingasebenziyo, njenge-nitric okanye i-citric acid. Oku kususa i-iron engaphezulu kwaye kubangele ukwakheka komaleko we-chromium oxide ongasebenziyo.

3. Ukuhlamba kunye nokomisa
   Emva kokuhlamba nge-asidi, izinto ziyahlanjwa kakuhle ngamanzi acocekileyo aze omiswe. Oku kuqinisekisa ukuba akukho asidi okanye ungcoliseko oluhlala phezu komphezulu.

Isiphumo kukuba umphezulu ogudileyo nozinzileyo ngokweekhemikhali omelana nokugqwala nokuba kwiindawo ezinzima.

Kutheni ukungabi namdla kubalulekile

Nangona intsimbi engagqwaliyo ine-chromium kwaye sele ikwazi ukumelana nokugqwala, ukucubungula ngoomatshini okufana nokusika, ukuwelda, okanye ukwenza i-machining kunokungenisa intsimbi ekhululekileyo kumphezulu. Ezi nxalenye zentsimbi zinokubangela ukugqwala kwendawo ukuba azisuswanga.

I-Passivation ibuyisela ukuthembeka komphezulu wesinyithi ngokuthi:

• Ukususa ungcoliseko

• Ukuphucula ukumelana nokugqwala

• Ukuphucula ukuqina kwiindawo ezinobundlobongela

• Ukuxhasa imigangatho yokucoca kunye neyococeko

Kwimizi-mveliso efana nokulungisa ukutya, amayeza, kunye neenqwelo-moya, ukungasebenzi kakuhle akukhuthazwa nje kuphela — kudla ngokufuneka.

Izicelo eziqhelekileyo zeNtsimbi Engagqwaliyo Engagqwaliyo

I-Passivation isetyenziswa kakhulu kumacandelo afuna ukuxhathisa ukugqwala ixesha elide kunye nokucoceka. Eminye imizekelo ibandakanya:

• Izixhobo Zokucubungula Ukutya Neziselo
  Ukuthintela ungcoliseko kunye nokukhula kweebhaktheriya kwiindawo ezicocekileyo.

• Izixhobo zamayeza nezoNyango
  Izixhobo kunye nezinto zotyando mazingabi nampembelelo kwaye zingagqwali.

• Ishishini leoyile negesi
  Ukwandisa ubomi bezinto ezivezwa kwiikhemikhali, amanzi anetyuwa, okanye ukufuma okuphezulu.

• Ukuveliswa kweeSemiconductor
  Iindawo ezicocekileyo kakhulu zinciphisa ungcoliseko lwamasuntswana kwiindawo ezibalulekileyo.

i-sakysteelibonelela ngezinto zentsimbi engagqwaliyo ezingasetyenziswanga ezihlangabezana ne-ASTM A967 kunye neminye imigangatho yamazwe ngamazwe, ixhasa abathengi kulo lonke eli shishini linzima.

Imigangatho kunye neenkcukacha

Inkqubo yokudlulisa i-passivation ilawulwa yimigangatho eliqela yamazwe ngamazwe echaza iindlela ezilungileyo zokusebenza, iindlela zokuvavanya, kunye nokusetyenziswa kweekhemikhali. Ezi ziquka:

• I-ASTM A967: Inkcazo eqhelekileyo yonyango lokudlulisa iikhemikhali kwiindawo zentsimbi engagqwaliyo

• I-ASTM A380: Izikhokelo zokucoca, ukususa iikalika, kunye nokukhupha umoya

• I-ISO 16048: Umgangatho wehlabathi wokungasebenzisi

Le migangatho iqinisekisa ukuba inkqubo yenziwa ngokuchanekileyo kwaye umphezulu wokugqibela uhlangabezana neemfuno ezifunekayo zokumelana nokugqwala.

Indlela Yokwazi Ukuba Intsimbi Engagqwaliyo Ayisebenzi

Intsimbi engagqwaliyo engenziwanga nto ayibonakali yahlukile kakhulu kwiliso lenyama. Nangona kunjalo, uvavanyo olukhethekileyo olufana novavanyo lwe-copper sulfate, ukuvezwa komswakama ophezulu, okanye uvavanyo lwe-salt spray lunokuqinisekisa ukuba umaleko ongenziwanga nto ukhona kwaye uyasebenza.

Amanye amashishini afuna isiqinisekiso sezinto ezibonakalayo ukuze angasebenzi.i-sakysteelibonelela ngamaxwebhu apheleleyo kunye neengxelo zovavanyo lweemveliso ezingafakwanga xa ziceliwe.

Iingenelo zePassivation

Ukushwankathela, iingenelo eziphambili zokungasebenzisi intsimbi engenasici ziquka:

• Ukumelana okuphuculweyo kwimingxunya kunye nokugqwala

• Ubomi benkonzo ende kwiindawo ezisetyenziswayo

• Iindawo ezicocekileyo nezicocekileyo

• Ukusebenza okuphuculweyo kwiindawo ezineekhemikhali okanye ezinetyuwa

• Ukuthobela imigangatho yoshishino lwehlabathi

Ngokutyala imali kwizinto ezingasetyenziswanga, amashishini anciphisa iindleko zokulungisa, aphucula ukhuseleko, kwaye andisa ukuthembeka kwezixhobo.
