Ukuqina kuyinkomba yempahla evame ukusetshenziswa ezindaweni zemishini yezinto zensimbi.Iimboni yocingo lwensimbiyethula indlela yokuhlola esheshayo neyongayo yokuhlola ubulukhuni.Kodwa-ke, ngenxa yokuqina kwezinto zensimbi, ayikho incazelo ebumbene futhi ecacile ehlanganisa zonke izindlela zokuhlola ekhaya naphesheya.Ngokuvamile, ubulukhuni bensimbi buvame ukubhekwa njengokumelana kwempahla ekuguqulweni kwepulasitiki, imihuzuko, ukugqoka, noma ukusika.
Ikhoyili enkuluucingo lukathayelaekulungiseni ibanga lokucwiliswa kwe-zinc, gcina isivinini sangempela singashintshiwe, ngokusho kwe-t= KD ukunquma isikhathi sokucwiliswa kwe-zinc (1), lapho: isikhathi sokucwiliswa kwe-zinc sihlala njalo, thatha i-4-7D ububanzi bocingo lwensimbi mm , bese ulinganisa ibanga lokucwiliswa kwe-zinc.Ngokulungisa ibanga lokucwilisa i-zinc, isikhathi sokucwiliswa kwe-zinc sentambo yensimbi yezicaciso ezihlukahlukene singafinyezwa ngama-5s ngokwesilinganiso.Ngale ndlela, ukusetshenziswa kwe-zinc ngethani locingo lwensimbi kuyehla kusuka ku-61kg kuya ku-59.4kg.
I-Hot dip galvanizing ise-hot melt zinc liquid dip plating, isivinini sokukhiqiza, ukunamathela okuwugqinsi kodwa okungalingani, imakethe ivumela ukushuba kwama-microns angu-45, kufika kuma-microns angu-300 ngaphezulu.Imnyama ngombala, idla insimbi eningi ye-zinc, yenza ungqimba olungenayo olunesisekelo sensimbi, futhi inokumelana nokugqwala okuhle.Idiphu elishisayogalvanizingingagcinwa amashumi eminyaka endaweni yangaphandle.Ukuvikelwa kwe-zinc enamathela ku-matrix yensimbi kunezimiso ezimbili: ngakolunye uhlangothi, nakuba i-zinc isebenza kakhulu futhi kulula ukuyikhipha kune-iron, kodwa ifilimu yayo ye-oxide ayikhululekile futhi ihlangene njenge-iron oxide.Ungqimba oluminyene lwe-oxide olwakhiwe phezulu luvimbela ukuqhubekela phambili kwe-oxidation ye-zinc ngaphakathi.
Ikakhulukazi ngemva kokudlula ungqimba lwama-galvanized, ingaphezulu lesendlalelo se-oxide likhulu futhi lihlangene, ngokwalo linokumelana okuphezulu kwe-oxidation.Ngakolunye uhlangothi, lapho ebusweni theokufakwe uthayelaungqimba lonakele, edalula ingaphakathi yensimbi matrix, ngoba zinc iyasebenza ngaphezu kwensimbi, zinc uyothwala indima yokudela anode zinc, zinc uzobe oxidized ngaphambi kwensimbi, ukuze ukuvikela ungqimba iron ngeke zilimale.
