Ngokubhekiselele kwindlela ediphulwe ngayo umbhobho wentsimbi, inkqubo ye-galvanizing ye-hot-dip iphumela kwibhondi yesinyithi phakathi kwe-zinc kunye nentsimbi kunye noluhlu lwe-alloys ye-iron-zinc eyahlukileyo. Umgca wokutshiza oqhelekileyo wediphu usebenza ngolu hlobo lulandelayo:
1. Intsimbi ihlanjululwa ngokusebenzisa isisombululo se-caustic. Oku kususa ioli/igrisi, ubumdaka, kunye nepeyinti.
2. Isisombululo sokucoca i-caustic siyahlanjululwa.
3. Intsimbi ifakwe kwisisombululo se-acidic ukususa isikali sokugaya.
4. Isisombululo se-pickling siyahlanjululwa.
5. I-flux, ehlala i-zinc ammonium chloride isetyenziswa kwintsimbi ukunqanda i-oxidation yendawo ecociweyo ekuvezweni emoyeni. I-flux ivumelekile ukuba yome kwintsimbi kwaye incedise kwinkqubo ye-zinc ye-liquid yokumanzisa kunye nokunamathela kwintsimbi.
6. Intsimbi ifakwe kwibhafu ye-zinc etyhidiweyo kwaye igcinwe apho de iqondo lokushisa lentsimbi lilingane kunye nelo bhafu.
7. Intsimbi ipholile kwi-tank yokucima ukunciphisa ubushushu bayo kwaye inqanda ukuphendula okungafunekiyo kwengubo esanda kwakhiwa kunye nomoya.
Ngokobuchwephesha, igalvanization yinkqubo yokugquma intsimbi kunye nentsimbi enomaleko we-zinc ngokuntywiliselwa isinyithi kwibhafu ye-zinc etyhidiweyo kubushushu obumalunga ne-840 °F (449 °C). Xa ityhilekile emoyeni, i-zinc esulungekileyo (Zn) idibana neoksijini (O2) yenze i-zinc oxide (ZnO), ethi iphinde idibane nekharbon dayoksidi (CO2) yenze i-zinc carbonate (ZnCO3), ingwevu eqheleke buthuntu, yomelele ngokufanelekileyo. izinto ezikhusela intsimbi engaphantsi kwi-corrosion eqhubekayo kwiimeko ezininzi. Ngokubanzi, umbhobho otshisiweyo otshisiweyo oshushu unexabiso eliphezulu lombhobho wentsimbi kunezinye iindidi eziqhelekileyo zombhobho osetyenziswayo ngenxa yeendleko eziphezulu zokwenziwa kwawo kwimarike.
Ukusetyenziswa okusebenzayo, njengezinye iinkqubo zokukhusela i-corrosion, i-galvanizing ikhusela kakhulu iimveliso zetsimbi ngokusebenza njengomqobo phakathi kombhobho wensimbi kunye nomoya. Nangona kunjalo, i-zinc yintsimbi ye-electronegative ngakumbi xa kuthelekiswa nentsimbi. Olu luphawu olulodwa lwe-galvanizing. Ngokukodwa, xa i-galvanized coating yonakalisiwe kwaye imveliso yensimbi ibonakaliswe emoyeni, i-zinc inokuqhubeka nokukhusela insimbi nge-galvanic corrosion. Ngaphezu koko, ukuba le ngubo iyenzeka ukuba ikrwelwe okanye igrunjwe, ukhuselo lwesibini lwe-zinc lubizwa ukuba lukhusele intsimbi ngesenzo segalvanic. Kwilitye lokusila, ubukhulu bezinc bulawulwa lixesha elintywiliselwa ngalo inxalenye nganye kwibhafu yezinki etyhidiweyo kwakunye nesantya ekhutshwa ngaso. Igama elithi “ukudipha kabini” libhekisa kumalungu amakhulu kakhulu ukuba angangena kwiketile yokugalela amanzi kwaye kufuneka aditshwe kwicala elinye ngexesha. Ayibhekiseli kubunzima bokwaleka olongezelelweyo. Njengomenzi wemibhobho yentsimbi yobuchwephesha eTshayina, sizibophelele ekuveliseni iintlobo ezahlukeneyo zentsimbi yombhobho kwiiprojekthi zakho. Ukuze ufumane inkcazelo engakumbi, ungaqhagamshelana nathi nanini na.
