Iphepha le-VCI lokulwa nomhlwa lazisa:

Yintoni ukuthintela ukugqwala kwesigaba somphunga?

Okokuqala qonda ukuba yintoni umhlwa.

Umhlwa yinkqubo apho isinyithi sifuna ukubuyisela imeko yaso ye-oxide ezinzileyo, oko kukuthi, imo yaso yokuqala yeminerali. Okukhona amandla asetyenziswa ekucociseni iminerali ethile ibe yisinyithi, kokukhona izinga lokubola kwesinyithi likhawuleza. Umhlwa yinkqubo yokutshintsha kwe-electrochemical. Inani elincinci lee-ion zombane zikhona kumphezulu wesinyithi onganyangwanga, kwaye la masuntswana aya kuhamba ukusuka kwindawo yamandla aphezulu (i-anode) ukuya kwindawo yamandla aphantsi (i-cathode), ngaloo ndlela evelisa umbane, obizwa ngokuba yi-corrosion.

Iphepha lokulwa nomhlwa elikwisigaba somphunga licocwa ngenkqubo ekhethekileyo. Kwindawo evalekileyo, i-VCI ekwiphepha iqala ukunyibilikisa nokuguqula igesi yokulwa nomhlwa kubushushu obuqhelekileyo kunye noxinzelelo, esasazeka kwaye ingene kumphezulu wento yokulwa nomhlwa kwaye iyifunxe ukuze yenze umaleko wefilimu ekhuselayo enobukhulu bemolekyuli enye, ngaloo ndlela ifezekisa injongo yokulwa nomhlwa.

Iimpawu zephepha lokuthintela umhlwa elisebenza ngesigaba somphunga

1. Ukupakisha okungenawo ioyile, akukho mafutha, akukho mafutha asetyenziswayo kunye neenkqubo zokucoca, okonga iindleko zabasebenzi kunye nexesha.

2. I-VCI esebenza kakuhle iqulethwe ngokulinganayo kwiphepha lokulwa nomhlwa, elinokukhawuleza libe nefuthe lokulwa nomhlwa emva kokupakishwa.

3. Ukuthintela umhlwa okusebenzayo kunokufezekiswa nokuba akudibani ngqo nesinyithi, ingakumbi kwiziqwenga zesinyithi ezinembonakalo enzima.

4. Inemisebenzi emibini yokuthintela umhlwa kunye nokupakisha.

5. Xa ithelekiswa nokupakishwa kwe-vacuum, ixabiso layo liphantsi kwaye kulula ukuyisebenzisa.

6. Icocekile, ayinabungozi, ayinatyhefu, inobuhlobo nokusingqongileyo kwaye ikhuselekile.

Iintsimbi ezisebenzayo:

isinyithi sesinyithi, intsimbi ye-alloy, isinyithi esityhidiweyo, ubhedu, ubhedu, isinyithi esine-electroplated, i-zinc kunye ne-alloy, i-chromium kunye ne-alloy, i-cadmium kunye ne-alloy, i-nickel kunye ne-alloy, i-tin kunye ne-alloy, i-aluminium kunye ne-alloy kunye nezinye izixhobo kunye neemveliso zesinyithi.

Amanyathelo okusebenzisa:

1. Iphepha lokulwa nomhlwa kufuneka lisondelelene nomphezulu wento yokulwa nomhlwa, kwaye akufuneki kubekho mqobo phakathi kwawo.
2. Ngaphambi kokupakisha, umphezulu wento elwa nomhlwa kufuneka ucoceke, wome kwaye ungabi namasuntswana angaphandle.
3. Ukuba umphezulu wento elwa nomhlwa uqhelekile, indlela yokugubungela ngokupheleleyo inokuba
4. Nxiba iiglavu ezicocekileyo xa upakisha, kwaye ungazichukumisi izinto ezithintela umhlwa ngezandla ezingagqunywanga.
5. Ayinazo i-nitric acid, i-phosphoric acid, i-chromic acid, i-silicon kunye nezinye iintsimbi ezinzima, kwaye ikhuselekile kwaye ayinangcoliseko.

Ixesha lokuthintela umhlwa:

Iminyaka eyi-1 ukuya kweye-3 (sebenzisa ngokweemfuno kunye neenkcukacha)

Ukugcinwa nokugcinwa: Ukupakisha okuvaliweyo, kugcinwe kwindawo epholileyo neyomileyo, kuphephe ukukhanya kwelanga ngqo, kuphephe ukudibana nemithombo yomlilo kunye nezinto ezirhabaxa. Ixesha lokugcinwa kwempahla ziinyanga ezili-12 ukususela kumhla wokuhanjiswa kwayo.

Inkqubo yokuvelisa:

I-virgin pulp yenziwe nge-pulp yomthi we-kraft engaxutywanga, itshayiwe, ilinganiswe, izaliswe (izinto eziphathekayo), ikopishwe kumatshini wephepha, ize igqunywe nge-rust remover (efana ne-sodium benzoate, i-sodium benzoate kunye nomxube we-sodium nitrite) kwiphepha elisezantsi ngokuyidipha, ukuyixuba okanye ukuyincamathisela ngeglue, ize yomiswe.

Iphepha elilwa nomhlwa linokuqina okuphezulu kunye nokumelana nokugoba, kodwa alinazo naziphi na izinto ezinokubangela umhlwa wesinyithi. Lisetyenziselwa ukupakisha isinyithi esityhidiweyo, isinyithi, iimveliso zesinyithi ezigayiweyo, kunye nokupakisha isinyithi esinemibala emininzi seemveliso ze-alloy zobhedu kunye nobhedu. Ukuba elinye icala lephepha elisisiseko ligqunywe nge-paraffin wax okanye i-polyethylene resin, kwaye elinye icala ligqunywe nge-vapor phase antirust inhibitor, iphepha elilwa nomhlwa lesigaba somphunga lingenziwa.

Umahluko phakathi kwetekhnoloji yokulwa nomhlwa yesigaba somphunga kunye netekhnoloji yendabuko yokulwa nomhlwa;

Ngenxa yempembelelo yemozulu, indawo, izixhobo zemveliso kunye nezinye izinto, izinto ezininzi zokusebenza ziya kuba nomhlwa kwiindawo zazo. Xa ukhetha iimveliso ezichasene nomhlwa, abahlobo abaninzi abazi ukuba bangakhetha njani iphepha elichasene nomhlwa elinomphunga kunye nephepha lendabuko elichasene nomhlwa, ngoko makhe sazise umahluko phakathi kwephepha elichasene nomhlwa elinomphunga kunye nephepha lendabuko elichasene nomhlwa.

Iphepha elichasene nomhlwa elikwisigaba somphunga liyimpahla ekhethekileyo yokupakisha echasene nomhlwa, esekelwe kwiphepha elikhethekileyo elingathathi cala, eligqunywe ngezinto ezahlukeneyo ezikhethekileyo-i-VCI, kwaye emva kochungechunge lweenkqubo zokucubungula emva koko. Phakathi kwezinto ezininzi kwishishini lokupakisha, iphepha elichasene nomhlwa elikwisigaba somphunga luhlobo lwemveliso yobuchwepheshe obuphezulu, kwaye iteknoloji yalo ephambili ikwi-VCI. Itekhnoloji ye-VCI yitekhnoloji ebanzi edibanisa ukwenziwa kwezinto eziphilayo, ikhemistri yomzimba, ukugqwala kunye nokukhusela, izixhobo zesinyithi, ukucubungula iphepha kunye netekhnoloji ye-polymer. Iinkqubo ezahlukeneyo ze-VCI zinomahluko omkhulu kukhuseleko, ukusebenza kakuhle okuphezulu, ukhuseleko lokusingqongileyo kunye nokusetyenziswa, ngoko ke zibonakaliswa njengeemveliso ezineefom kunye nemisebenzi eyahlukeneyo.

Iphepha lemveli lokulwa nomhlwa liphepha lokulwa nomhlwa elifana nohlobo lokuqhagamshelana okanye iphepha lokulwa nomhlwa elinomlinganiselo omnye womphunga elinomlinganiselo omnye wokuthintela umhlwa. Isalathisi, imeko yomphezulu, iimpawu zomzimba kunye nesiphumo sokulwa nomhlwa sephepha lemveli lokulwa nomhlwa azilunganga kangako. Nangona kunjalo, iphepha langoku lokulwa nomhlwa elinomgangatho ophezulu kunye ne-inhibitor yokubola ephantsi komphunga, lineempawu zokulwa nomhlwa kunye nokulwa nomhlwa ezihambelana nomphunga, ezinempembelelo entle, kwaye zinokufikelela kwiindlela ezahlukeneyo zokwakha ukuhlangabezana neemfuno ezahlukeneyo zamandla okupakisha.
