Isingeniso
Imboni yensimbi ibone ukuthuthuka okuphawulekayo phakathi neminyaka edlule, ngezindlela ezihlukahlukene zokuvikela ezithuthukisa ukuqina nokusebenza kwemikhiqizo yensimbi. Phakathi kwalokhu, amashidi ensimbi ashisiwe ashisayo avele njengamandla amakhulu emakethe. Ukuthandwa kwabo okukhulayo akukhona nje ukuthambekela kodwa kubonisa izakhiwo zabo eziphakeme kanye nokusebenza kahle kwezindleko. Ezimbonini, ozakwethu besiteshi, nabasabalalisi, ukuqonda izizathu ezidala lokhu kubusa kubalulekile ukuze kubekwe amasu endaweni yokuncintisana. Lokhu kuhlaziya okuphelele kuhlolisisa izici ezenza amashidi ensimbi ashisiwe ashisayo abe yinketho ekhethwayo ezinhlelweni eziningi, okugqamisa umthelela wawo ekuguquguqukeni kwemboni.
Esinye sezici ezibalulekile ezinomthelela ekwamukelweni okusabalele kwamashidi ensimbi ashisiwe ashisayo ukumelana kwawo nokugqwala okukhethekile. Inqubo ecophelelayo yokufaka uthayela inika i-zinc coating eqinile evikela insimbi engaphansi kubahlaseli bemvelo. Ngenxa yalokho, lezi AmaSpredishithi Ensimbi Akhandiwe anikeza ukuphila kwesevisi okunwetshiwe, ehlisa izindleko zokulungisa futhi athuthukise ukwethembeka komkhiqizo.
Uhlolojikelele Lwamashidi Ensimbi Afakwe Ngamanzi Ashisayo
Amashidi ensimbi acwilisiwe ashisayo akhiqizwa ngokucwilisa insimbi kubhavu we-zinc encibilikisiwe, okuholela ekuxhumaneni kwensimbi phakathi kwezinki nensimbi. Le nqubo yakha uchungechunge lwezingqimba ze-zinc-iron alloy, ezihlinzeka ngokuvikeleka okuphezulu kokugqwala uma kuqhathaniswa nezinye izindlela zokumboza. Umlando wokwenza izitishi uhlehlela emuva ngekhulu le-18, kodwa yintuthuko yesimanje kwezobuchwepheshe eyenze yaphelela inqubo yediphu eshisayo, okwenza isebenze kahle futhi ihambisane nemvelo.
Izici eziyingqayizivele ze-galvanization ecwilisiwe eshisayo ihlanganisa ukushuba okufanayo kwe-coat, ukunamathela okuqinile, kanye nekhono lokuvikela insimbi ngisho nasezimweni ezinzima. Lokhu kwenza amashidi ensimbi ashisiwe ashisayo abe yinketho efanelekile yokwakha, izimoto, kanye namaphrojekthi wengqalasizinda lapho ukuphila isikhathi eside nokuqina kubaluleke kakhulu.
Inqubo Yokukhiqiza Ye-Hot Dipped Galvanization
Inqubo yokukhiqiza amashidi ensimbi acwilisiwe ashisayo ihilela izinyathelo ezimbalwa ezibucayi zokuqinisekisa ikhwalithi yokunamathela efanelekile. I-substrate yensimbi ibhekana nokulungiswa kwendawo, okuhlanganisa ukwehlisa, ukuqoqa, nokuguquguquka. Lezi zigaba zisusa ukungcola nama-oxides, okuvumela isibopho esiqinile phakathi kwe-zinc coating nensimbi.
Ukulungiswa kwendawo
Ukulungiswa kwendawo engaphezulu kubalulekile ukuze kuzuzwe ukunamathela kwekhwalithi ephezulu. Ukwehlisa amafutha kususa amafutha nokungcola, kuyilapho ukucosha kususa ukugqwala nesikali sokugaya kusetshenziswa izixazululo ezine-asidi. I-Fluxing isebenzisa ungqimba oluvikelayo oluvimbela ukufakwa kwe-oxidation ngaphambi kokucwiliswa kubhavu we-zinc, okuqinisekisa indawo ehlanzekile yokufaka uthayela.
Inqubo Yokugalela
Phakathi nenqubo yokufaka uthayela, insimbi elungisiwe icwiliswa ku-zinc encibilikisiwe emazingeni okushisa acishe abe ngu-450°C (842°F). Isikhathi sokucwiliswa siyahlukahluka ngokuya ngobukhulu bensimbi nesisindo esifiselekayo sokumboza. Ukusabela kwe-metallurgical kwenzeka, okwenza izingqimba ze-zinc-iron alloy ezihlinzeka ngokuvikeleka okuqinile.
Ukwelashwa Kwangemva Kwe-Galvanizing
Ngemuva kokufakwa kwe-galvanization, amashidi ensimbi angase abhekane nokwelashwa kwangemuva okufana nokucisha, ukudlula, noma ukugoqa kwesikhumba. Lezi zinqubo zithuthukisa ukuphela kwendawo, zinciphisa ubungozi bokugqwala okumhlophe, futhi zithuthukise ukubukeka kwezinqubo zokukhiqiza ezilandelayo.
Izinzuzo Ezimqoka Zamashidi Ensimbi Afakwe Ngamanzi Ashisayo
Ukubusa kwamashidi ensimbi ashisiwe ashisayo emakethe kubalulwe ezinzuzweni ezimbalwa ezibalulekile ezibenza bahluke kwezinye izinto ezisetshenziswayo kanye nokunameka.
I-Superior Corrosion Resistance
Ukugqwala kuyinkinga enkulu ekufakweni kwensimbi, okuholela ekuhlulekeni kwesakhiwo nokwenyuka kwezindleko zokuyilungisa. I-zinc enamathela kumashidi ensimbi ashisiwe ashisayo isebenza njenge-anode yomhlatshelo, igqwala ngokukhethekile ukuze ivikele insimbi engaphansi. Lokhu kuvikelwa kwe-cathodic kuqinisekisa ukuthi noma ngabe ukumbozwa konakalisiwe, insimbi eveziwe ihlala ivikelekile ekugqwaleni.
Izindleko-Ngempumelelo
Nakuba izindleko zokuqala zamashidi ensimbi ashisiwe ashisayo zingase zibe phezulu kunensimbi engamboziwe, ukonga kwesikhathi eside kukhulu. Impilo yesevisi eyandisiwe kanye nesidingo esincishisiwe sokunakekelwa noma ukushintshwa kuhumushela ekwehliseni izindleko zomjikelezo wokuphila. Kumaphrojekthi amakhulu, lokhu kusebenza kahle kwezindleko kuyinzuzo enkulu.
Ukuhlukahluka kanye Nesikhalazo Sobuhle
Amashidi ensimbi acwilisiwe ashisayo anikeza ukuguquguquka kwezicelo ngenxa yokubukeka kwawo nokuhambisana nezinqubo ezihlukahlukene zokukhiqiza. Zingenziwa kalula, zipendwe, noma zenziwe zibe yizimo eziyinkimbinkimbi. Ukwengeza, isiphetho esipelingiwe noma esibushelelezi se-galvanized coating sinikeza isikhalazo sobuhle esifiselekayo ezinhlelweni zezakhiwo.
Ukusimama Kwemvelo
Esikhathini lapho ukucatshangelwa kwemvelo kubaluleke kakhulu, amashidi ensimbi ashisiwe ashisayo ahambisana nezinqubo ezizinzile. I-Zinc nensimbi kokubili kugaywa kabusha ngo-100% ngaphandle kokulahlekelwa izakhiwo. Ukuqina kwensimbi ethathiwe kunciphisa ukusetshenziswa kwensiza ngokunciphisa isidingo sokushintshwa.
Amathrendi Emakethe kanye Nezinto Ezifunwayo
Isidingo somhlaba wonke samashidi ensimbi afakwe uthayela ashisayo silokhu sikhula njalo.

Izembatho ezishisayo ezicwilisiwe ezinamathayela, ngakolunye uhlangothi, zinikeza kokubili umgoqo kanye nokuvikelwa kwe-cathodic, ukunciphisa izidingo zokunakekelwa.
Izinselelo Nemikhawulo
Naphezu kwezinzuzo eziningi, amashidi ensimbi ashisiwe ashisayo abhekana nezinselelo ezithile abathintekayo bemboni okufanele bazicabangele.
Ukuqina Kwensimbi kanye Nokufana Kokunamathela
Ukuthola ukujiya kokugqoka okufanayo kuma-substrates ensimbi amancane kakhulu noma awugqinsi kungaba inselele. Ukwehluka kogqinsi bokunamathela kungase kuthinte ukusebenza nobuhle bomkhiqizo wokugcina. Izindlela zokulawula ezithuthukisiwe ezitshalweni zokugalela amatshe zibalulekile ukuze kuncishiswe lolu daba.
Ukugqwala Okumhlophe
Ukugqwala okumhlophe wuhlobo lokugqwala olwenzeka ezindaweni ezinothayela, ikakhulukazi lapho zichayeke kumswakama ngaphandle kokungena komoya ngendlela. Ingakwazi ukwehlisa ukubukeka futhi, ezimweni ezinzima, ithinte izakhiwo zokuzivikela zokugqoka. Ukugcinwa okufanele kanye nezinqubo zokuphatha kuyadingeka ukuvimbela ukugqwala okumhlophe.
Ukucatshangelwa kwe-Welding kanye Nokwenziwa
Ukushisela insimbi ebinatha kudinga ukuqapha okukhethekile ngenxa yokukhishwa kwentuthu ye-zinc oxide, engaba yingozi. Abakhi kumele basebenzise umoya owanele kanye nezinto zokuzivikela. Ukwengeza, ukushisela kungashisa i-zinc enamathela endaweni, okudinga ukwelashwa kwangemuva kokushisela ukubuyisela ukumelana nokugqwala.
Ukubukeka Kwesikhathi Esizayo Kwamashidi Ensimbi Afakwe Afakwe Ngamanzi Ashisayo
Ikusasa lamashidi ensimbi ashisiwe ashisayo libonakala lithembisa, ngocwaningo oluqhubekayo nentuthuko egxile ekuthuthukiseni izakhiwo nokwenziwa kwazo.
Izindlela Ezintsha Zezobuchwepheshe
Intuthuko kubuchwepheshe bokwenza ama-galvanizing ihlose ukuthuthukisa ukunamathela kokunamathela, ukunciphisa umthelela wemvelo, nokwandisa ukusetshenziswa kwamandla. Izindlela ezintsha ezifana nemigqa eqhubekayo yokufaka uthayela enesivinini esiphezulu zikhuphula ukusebenza kahle kokukhiqiza, zihlangabezana nesidingo esikhulayo semakethe.
