Izimbali ze-zinc zimelela isimo sobuso se-coil ecwebezelayo e-zinc eshisayo. Lapho umugqa wensimbi udlula ebhodweni le-zinc, ubuso bawo bumbozwa nge-zinc encibilikisiwe. Ngesikhathi sokuqina kwemvelo kwalolu ngqimba lwe-zinc, i-nucleation kanye nokukhula kwamakristalu e-zinc kuphumela ekwakhekeni kwezimbali ze-zinc.
Igama elithi “zinc bloom” livela kumakristalu e-zinc aphelele abonisa isimo esifana neqhwa. Isakhiwo sekristalu ye-zinc esiphelele sifana nesimo seqhwa noma inkanyezi enezinhlangothi eziyisithupha. Ngakho-ke, amakristalu e-zinc akhiwe ngokuqina ebusweni bomcu ngesikhathi se-hot-dip galvanizing cishe azosebenzisa iphethini yeqhwa noma inkanyezi enezinhlangothi eziyisithupha.
Ikhoyili yensimbi egayiwe ibhekisela kumashidi ensimbi aphathwa ngezinqubo ze-hot-dip galvanizing noma ze-electrogalvanizing, ngokuvamile ezinikezwa ngesimo sekhoyili. Inqubo ye-galvanizing ihilela ukubopha i-zinc encibilikisiwe kukhoyili yensimbi ukuze kuthuthukiswe ukumelana kwayo nokugqwala futhi kwandiswe impilo yayo yesevisi. Lokhu kusetshenziswa kuthola ukusetshenziswa okubanzi kuzo zonke izigaba zokwakha, izinto zasekhaya, izimoto, imishini, kanye neminye imikhakha. Ukumelana kwayo okuhle kakhulu nokugqwala, amandla, kanye nokusebenza kahle kwenza ifaneleke kakhulu ezindaweni zangaphandle noma ezinomswakama.
Izici ezibalulekile zeikhoyili yensimbi ehlanganisiwefaka:
1. Ukumelana Nokugqwala: Ukwembozwa kwe-zinc kuvikela insimbi engaphansi ekungcolisweni nasekugqwaleni.
2. Ukusebenza Kahle: Kungasikwa, kugotshwe, kushiselwe, futhi kucutshungulwe.
3. Amandla: Amandla aphezulu nokuqina kwenza ikwazi ukumelana nezingcindezi nemithwalo ethile.
4. Ukuqeda umphezulu: Umphezulu obushelelezi ofanele ukupenda nokufutha.
Ukubumba izimbali kubhekisela ekwakhekeni kwemvelo kwezimbali ze-zinc ebusweni ngesikhathi sokuminyana kwe-zinc ngaphansi kwezimo ezijwayelekile. Ukubumba izimbali okungenazimbali, nokho, kudinga ukulawula amazinga okuhola ngaphakathi kwemingcele ethile noma ukusebenzisa ukwelashwa okukhethekile ngemuva kokwelashwa emgqeni ngemva kokuphuma ebhodweni le-zinc ukuze kufezwe ukuphela okungenazimbali. Imikhiqizo yokuqala ebumba i-hot-dip yayinezimbali ze-zinc ngenxa yokungcola ebhavini le-zinc. Ngenxa yalokho, izimbali ze-zinc zazihlotshaniswa ngokujwayelekile nokubumba i-hot-dip. Ngokuthuthuka kwemboni yezimoto, izimbali ze-zinc zaba yinkinga ngezidingo zokumboza kumashidi ezimoto abumba i-hot-dip. Kamuva, ngokunciphisa okuqukethwe kwe-lead kuma-ingots e-zinc kanye ne-zinc encibilikisiwe kuya emazingeni angamashumi e-ppm (izingxenye ngesigidi), sathola ukukhiqizwa kwemikhiqizo engenazo noma izimbali ze-zinc ezincane.

Izimboni ezikhetha amashidi angenazinc:
1. Ukukhiqiza Izimoto: Amaphaneli angaphandle kanye nezingxenye zokuhlobisa zangaphakathi zidinga ikhwalithi ephezulu. Ukuphela okubushelelezi kwensimbi ehlanganisiwe engenazinki kwenza kube lula ukunamathela ngopende kanye nokumboza, okuqinisekisa ukukhanga kobuhle kanye nekhwalithi.
2. Izinto Zasekhaya Ezisezingeni Eliphezulu: Izingcezu zangaphandle zamafriji asezingeni eliphezulu, ama-air conditioner, njll., zidinga ukubukeka okuhle kakhulu kanye nokuba yisicaba ukuze kuthuthukiswe ukuthungwa komkhiqizo kanye nenani elibonakalayo.
3. Imboni Yezinto Eziphathekayo: Ezindlini zemikhiqizo ye-elekthronikhi kanye nezingxenye zesakhiwo sangaphakathi, insimbi ekhandiwe engenazinki ivame ukukhethwa ukuqinisekisa ukuhanjiswa kahle kukagesi kanye nokusebenza kahle kokwelashwa kwendawo.
4. Imboni Yamadivayisi Ezokwelapha: Njengoba kunezidingo eziqinile zekhwalithi yomkhiqizo kanye nokuhlanzeka, insimbi engenazinki ihlangabezana nesidingo sokuhlanzeka kanye nokushelela.
Izindleko Zokucatshangelwa
Amashidi ensimbi ahlanganisiwe anezimbali ze-zinc ahilela izinqubo zokukhiqiza ezilula kakhulu kanye nezindleko eziphansi. Ukukhiqizwa kwamashidi ensimbi ahlanganisiwe angenazo i-zinc kuvame ukudinga ukulawulwa kwenqubo okuqinile, okuholela ezindlekweni eziphakeme kancane.
