Ukuqina kungenye yezinkomba ezisetshenziswa kakhulu ezindaweni zemishini yezinto zensimbi.Indlela yokuhlola esheshayo neyongayo yokuhlola ubulukhuni yethulwa efekthri yocingo.Kepha ngobulukhuni bezinto zensimbi, ayikho incazelo ebumbene futhi ecacile ehlanganisa zonke izindlela zokuhlola ekhaya nakwamanye amazwe.Ngokuvamile, ubulukhuni bensimbi buvame ukucatshangelwa njengokumelana kwento eguquguqukayo yepulasitiki, imihuzuko, ukuguga, noma ukusika.
Ekulungiseni ibanga lokucwilisa elikhuluucingo lukathayela, gcina isivinini sangempela singashintshiwe, bese unquma isikhathi sokucwilisa (1) ngokusho kwe-T = KD, lapho: T iwukuguquguquka kwesikhathi sokucwilisa, thatha u-4-7d ububanzi bocingo lwensimbi mm, bese ulinganisa ukucwiliswa. ibanga.Ngokulungisa ibanga lokucwilisa i-zinc, isikhathi sokucwilisa i-zinc yocingo lwensimbi lokucaciswa okuhlukahlukene sifinyezwa ngama-5s ngokwesilinganiso kunaleso ngaphambi kokulungiswa.Ngale ndlela, ukusetshenziswa kwe-zinc kuyancishiswa, futhi ukusetshenziswa kwe-zinc ngethani locingo lwensimbi kuyehla kusuka ku-61kg kuya ku-59.4kg.
I-hot dip galvanizing isekushiseni kwe-zinc dip plating encibilikisiwe, isivinini sokukhiqiza, ukunamathela okuwugqinsi kodwa okungalingani, ubukhulu bemakethe buvumela ama-microns angu-45, kufika kuma-microns angu-300 noma ngaphezulu.Umbala umnyama, ukusetshenziswa kwensimbi ye-zinc, kanye nensimbi ye-matrix ukwenza isendlalelo sokungena, ukumelana nokugqwala kuhle, indawo eshisayo yangaphandle enamalahle ingagcinwa amashumi eminyaka.Kunezimiso ezimbili zokuvikela i-zinc enamathela ku-matrix yensimbi: ngakolunye uhlangothi, nakuba i-zinc isebenza kakhulu futhi kulula ukuyikhipha kune-iron, ifilimu yayo ye-oxide ayikhululekile njenge-iron oxide futhi iminyene.Ukwakheka kongqimba oluminyene lwe-oxide ebusweni kuvimbela ukuqhubekela phambili kwe-oxidation ye-zinc ngaphakathi.
Ikakhulukazi ngemva kokudlula ungqimba olunamanzi, ungqimba lwe-oxide ongaphezulu luminyene kakhulu, ngokwalo lunokumelana okuphezulu kwe-oxidation.Ngakolunye uhlangothi, lapho ungqimba olungaphezulu lwe-zinc coating lonakalisiwe, luveza i-matrix yensimbi yangaphakathi, ngoba i-zinc isebenza kakhulu kune-iron, i-zinc izoba nendima yomhlatshelo we-zinc anode, i-zinc izokhipha i-oxidize ngaphambi kwensimbi, ngaleyo ndlela ivikele ungqimba lwensimbi. emonakalweni.
