Sonke siyazi ukuba intsimbi eqhelekileyo iya kubola ukuba ivezwa emoyeni wangaphandle ixesha elide, ngoko ke ungakuphepha njani ukubola? Ngaphambi kokuba uphume kumzi-mveliso, iipali zezibane zesitalato kufuneka zifakwe i-hot-dip galvanize zize zitshizwe ngeplastiki, ngoko ke yintoni inkqubo yokufaka i-galvanize ye-iipali zezibane zesitalatoNamhlanje, ifektri yezibane zesitalato ezenziwe nge-galvanized TIANXIANG iza kuthatha wonke umntu ukuba ayiqonde.
Inxalenye ebalulekileyo yenkqubo yokwenziwa kweepali zokukhanya ezitalatweni kukufaka i-hot-galvanizing. I-hot-dip galvanizing, eyaziwa ngokuba yi-hot-dip galvanizing kunye ne-hot-dip galvanizing, yindlela esebenzayo yokulwa nokugqwala kwesinyithi kwaye isetyenziswa kakhulu kwizixhobo zesakhiwo sesinyithi kumashishini ahlukeneyo. Emva kokuba izixhobo zicoce umhlwa, zifakwa kwisisombululo se-zinc esinyibilikisiweyo malunga ne-500°C, kwaye umaleko we-zinc unamathela kumphezulu wenxalenye yentsimbi, ngaloo ndlela uthintela isinyithi ekugqwaleni.
Ixesha lokulwa nokugqwala xa kusetyenziswa i-hot-dip galvanizing lide, kodwa ukusebenza kokulwa nokugqwala kuxhomekeke kakhulu kwindawo esetyenziswa kuyo izixhobo. Ixesha lokulwa nokugqwala kwezixhobo kwiindawo ezahlukeneyo nalo lahlukile: iindawo ezinkulu zoshishino zingcoliswa kakhulu kangangeminyaka eli-13, iilwandle ngokubanzi ziyiminyaka engama-50 yokugqwala kwamanzi olwandle, amadlelo angaphantsi anokuba yiminyaka eli-104, kwaye izixeko ngokubanzi ziyiminyaka engama-30.
Ukuqinisekisa umgangatho, ukuthembeka kunye nokuqina kweepali zokukhanya zesitalato zelanga, intsimbi ekhethiweyo ikakhulu yintsimbi ye-Q235. Ukuqina okuhle kunye nokuqina kwentsimbi ye-Q235 zezona zilungileyo kwiimfuno zemveliso yeepali zokukhanya. Nangona intsimbi ye-Q235 inamandla kwaye iqinile, isadinga ukuphathwa nge-hot-dip galvanized kunye ne-plastic-sprayed anti-corrosion treatment. Ipali yokukhanya yesitalato ene-galvanized inokumelana okuhle nokugqwala, kulula ukuyigqwala, kwaye ubomi bayo benkonzo bunokufikelela kwiminyaka eli-15. I-hot-dip galvanized spray itshiza ngokulinganayo umgubo weplastiki kwipali yokukhanya, kwaye incamathisele ngokulinganayo umgubo weplastiki kwipali yokukhanya kubushushu obuphezulu ukuqinisekisa ukuba umbala wepali yokukhanya awuyi kutshabalala ixesha elide.
Umphezulu weipali yesibane sesitalato egalelweyoIkhanya kwaye intle, kwaye inomsebenzi wokudibanisa i-Q235 yentsimbi kunye nomaleko we-zinc alloy ngokuqinileyo, kwaye ibonakalisa ukumelana okuhlukileyo kokubola, ukuchasana ne-oxidation kunye nokuguguleka kwimozulu yokutshiza ityuwa yaselwandle kunye nomoya wezoshishino. I-Zinc ithambile, kwaye umaleko wayo we-alloy unamathela ngokuqinileyo kumzimba wentsimbi, ngoko ke iipali zokukhanya zesitalato ezigayiweyo zinokubethelwa kubanda, ziqengqwe, zitsalwe, zigotywe, njl. ngaphandle kokonakalisa uphahla. Isibane sesitalato esigayiweyo sinomaleko omncinci noxineneyo we-zinc oxide kumphezulu womaleko we-zinc, okunzima ukuwunyibilikisa emanzini. Ke ngoko, nangemihla yemvula, umaleko we-zinc unefuthe elithile lokukhusela kwisibane sesitalato, esandisa ubomi besibane sesitalato.
Ukuba unomdla kwipali yesibane sesitalato esine-galvanized, wamkelekile ukuqhagamshelana nathiifektri yezibane zesitalato ezigayiweyoTIANXIANG ukuyaFunda ngokugqithisileyo.
