Iimbonakalo
1. Ukukhuselwa kabini komaleko we-zinc:
Umaleko we-iron-zinc alloy oxineneyo (amandla okubopha aqinileyo) kunye nomaleko we-zinc ococekileyo wenziwa phezu komphezulu, nto leyo eyahlula umoya kunye nokufuma, nto leyo ebambezela kakhulu ukugqwala kwemibhobho yentsimbi.
2. Ukhuseleko lwe-anode yedini:
Nokuba i-coating yonakele kancinci, i-zinc iya kuqala ibole (ukhuseleko lwe-electrochemical), ikhusele i-substrate yentsimbi ekukhukulisekeni.
3. Ubomi obude:
Kwimeko eqhelekileyo, ubomi benkonzo bunokufikelela kwiminyaka engama-20-30, nto leyo ende kakhulu kunemibhobho yentsimbi eqhelekileyo (njengokuba ubomi bemibhobho epeyintiweyo bumalunga neminyaka emi-3-5)
Qhagamshelana Nathi ukuze ufumane iinkcukacha ezithe vetshe ngeeMibhobho zeNtsimbi eziGxotyiweyo.
Ukuntywila okushushuumbhobho we-galvanizedEzi zixhobo zisetyenziswa kakhulu kwizakhiwo (ezifana nee-trusses zefektri, i-scaffolding), ubunjineli bukamasipala (i-guardrails, iipali zokukhanya ezitalatweni, iipayipi zokuhambisa amanzi), amandla kunye namandla (iinqaba zokudlulisela, iibrakethi ze-photovoltaic), izibonelelo zezolimo (amathambo e-greenhouse, iinkqubo zokunkcenkceshela), imveliso yemizi-mveliso (iishelufu, imibhobho yokungenisa umoya) kunye neminye imimandla ngenxa yokumelana kwazo nokugqwala okugqwesileyo, amandla aphezulu kunye nobomi obude. Zibonelela ngokhuseleko olungenakugcinwa, olungabizi kakhulu noluthembekileyo kwiindawo zangaphandle, ezifumileyo okanye ezigqwalisayo ezinobomi benkonzo obufikelela kwiminyaka engama-20-30. Zisisombululo esikhethwayo sokulwa nokugqwala endaweni yeepayipi zentsimbi eziqhelekileyo.
Inkqubo yokuvelisa imibhobho ejikelezileyo edityanisiweyo nge-galvanized ilandela la manyathelo:
1. Izinto eziluhlaza Unyango lwangaphambi kwexesha: Khetha iikhoyili zentsimbi ezinekhabhoni ephantsi, zinqunqwe zibe yimicu enobubanzi obufanelekileyo, zifakwe i-pickle ukuze kususwe isikali, zihlanjwe ngamanzi acocekileyo, kwaye zomiswe ukuze kuthintelwe ukugqwala.
2. Ukubumba kunye nokuWelda: Imicu yentsimbi ifakwa kwi-roller press ize iqengqelwe kancinci kancinci ibe zii-billets zetyhubhu ezijikelezileyo. Umatshini wokuwelda osebenza rhoqo unyibilikisa imithungo ye-billet yetyhubhu kwaye uyicinezele kwaye uyiqinise, wenze ityhubhu ejikelezileyo enesikhumba esimnyama. Emva kokupholisa ngamanzi, iityhubhu ziyalinganiswa kwaye zilungiswe, kwaye emva koko zinqunyulwe ngokobude njengoko kufuneka.
3. Ukucoca Umphezulu(i-galvanizing ingahlulwahlulwa ibe yi-hot-dip galvanizing (i-hot-dip galvanizing) kunye ne-cold-dip galvanizing (i-electrogalvanizing), kunye ne-hot-dip galvanizing iyeyona ndlela iphambili kushishino (inika isiphumo esisebenzayo sokuthintela umhlwa)): Iipayipi ezihlanganisiweyo zifakwa kwi-pickling yesibini ukuze kususwe ukungcola, zifakwe kwi-galvanizing flux, zize zifakwe kwi-hot-dip kwi-zinc enyibilikisiweyo kwi-440-460°C ukuze zenze i-zinc alloy coating. I-zinc egqithisileyo isuswa ngemela yomoya, ize ipholiswe. (I-cold-dip galvanizing lulwahlulo lwe-zinc olufakwe kwi-electrodeposited kwaye alusetyenziswa rhoqo.)
4. Ukuhlolwa kunye nokuPakisha: Jonga umaleko we-zinc kunye nobukhulu, linganisa ukunamathela kunye nokumelana nokugqwala, hlela kwaye ubophe iimveliso ezifanelekileyo, uze uzibeke kwindawo yokugcina eneelebheli.
Inkqubo yokuvelisa imibhobho engqukuva engenamthungo egalelwe nge-galvanized ilandela la manyathelo:
1. Unyango lwangaphambi kokusetyenziswa kwezinto eziluhlaza: Iibhilethi zentsimbi ezingenamthungo (uninzi lwazo yintsimbi ekhabhoni ephantsi) ziyakhethwa, zinqunyulwe zibe ziinde ezizinzileyo, kwaye isikali se-oxide yomphezulu kunye nokungcola kuyasuswa. Iibhilethi emva koko ziyafudunyezwa ukuya kubushushu obufanelekileyo ukuze zigqobhozwe.
2. Ukubhoboza: Iibhilethi ezishushu ziqengqelwa kwiityhubhu ezingenanto ngesixhobo sokugalela esiqhoboshelayo. Emva koko iityhubhu zidluliselwa kwisixhobo sokugalela iityhubhu ukuze kulungiswe ubukhulu bodonga kunye nokujikeleza. Ububanzi bangaphandle buyalungiswa ngesixhobo sokugalela ubungakanani ukuze kwenziwe iityhubhu ezimnyama ezisemgangathweni. Emva kokupholisa, iityhubhu ziyanqunyulwa zibe nobude.
3. Ukugaya nge-galvanizing: Iityhubhu ezimnyama ezingenamthungo zifumana unyango lwesibini lokucola ukuze kususwe umaleko we-oxide. Emva koko ziyahlanjwa ngamanzi kwaye zifakwe kwi-agent ye-galvanizing. Emva koko zintywiliselwa kwi-zinc enyibilikisiweyo engama-440-460°C ukuze zenze i-zinc-iron alloy coating. I-zinc egqithisileyo isuswa ngemela yomoya, kwaye iityhubhu ziyapholiswa. (I-cold galvanizing yinkqubo yokubeka i-electrodeposition kwaye ayisetyenziswa rhoqo.)
4. Ukuhlolwa kunye nokuPakisha: Ukufana kunye nokunamathela kwengubo ye-zinc kuyahlolwa, kunye nobukhulu beepayipi. Iipayipi ezivunyiweyo emva koko ziyahlelwa, zihlanganiswe, ziphawulwe, kwaye zigcinwe ukuqinisekisa ukuba ziyahlangabezana nemigangatho yokuthintela umhlwa kunye nokusebenza koomatshini.
Iindlela zothutho lweemveliso ziquka uthutho lwendlela, uloliwe, ulwandle, okanye olusebenzisa iindlela ezininzi, ngokusekelwe kwiimfuno zabathengi.
Uthutho lwendlela, olusebenzisa iilori (umz., iiflethi), luyakwazi ukuguquguquka kumgama omfutshane ophakathi, nto leyo evumela ukuhanjiswa ngqo kwiindawo/kwiindawo zokugcina impahla ngokulula ukulayisha/ukukhulula impahla, lulungele iiodolo ezincinci okanye ezingxamisekileyo kodwa lubiza kakhulu kumgama omde.
Uthutho lwezithuthi luxhomekeke koololiwe bempahla (umz., iinqwelo ezigqunyiweyo/ezivulekileyo ezineentambo ezithintela imvula), ezifanelekileyo ukuthunyelwa okude, okuninzi okunexabiso eliphantsi kunye nokuthembeka okuphezulu, kodwa zifuna ukuthunyelwa okufutshane.
Uthutho lwamanzi (ngaphakathi/elwandle) ngeenqanawa zemithwalo (umz., iinqanawa ezinkulu/zesikhongozeli) luneendleko eziphantsi kakhulu, lufakela umgama omde, uthutho olukhulu oluya elunxwemeni/elunxwemeni lomlambo, kodwa lunomda wezibuko/umzila kwaye lucotha.
Uthutho olusebenzisa iindlela ezininzi (umz., uloliwe+indlela, ulwandle+indlela) lulinganisela iindleko kunye nexesha elifanelekileyo, lufanelekile kwiiodolo ezinqumla imimandla, umgama omde, umnyango nomnyango ezinexabiso eliphezulu.
