Ubukhulu be-hot-dip galvanized layer inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile, impilo ende yenkonzo nokunye.Izindleko ze-galvanizing ziphansi, indawo engaphezulu ayibushelelezi kakhulu, futhi ukumelana kwayo nokugqwala kubi kakhulu kunombhobho wamanzi oshisayo oshisayo.Inqubo yokwakheka kwe-hot-dip galvanizing layer iyinqubo yokwenza ingxubevange ye-iron zinc phakathi kwe-iron matrix kanye nongqimba lwezinc oluhlanzekile lwangaphandle.I-iron zinc alloy layer yakheka phezu kwendawo yokusebenza ngesikhathi sokushiswa kwe-hot-dip, okwenza inhlanganisela enhle phakathi kwensimbi ne-zinc ehlanzekile.Inqubo ingachazwa kalula ngokuthi: lapho i-workpiece yensimbi icwiliswa ku-zinc encibilikisiwe, i-zinc slag.Lapho i-workpiece isuswa kwisisombululo sokucwiliswa kwe-zinc, ungqimba lwe-zinc oluhlanzekile lwenziwa phezulu, okuyi-crystal ene-hexagonal.Okuqukethwe kwayo kwensimbi akukho ngaphezu kwe-0.003%.
Ipayipi elifakwe idiphu elishisayo:
Iwukwenza insimbi encibilikisiwe isabelane ne-iron matrix ukuze ikhiqize ungqimba lwengxubevange, ukuze kuhlanganiswe i-matrix kanye nokunamathela.Idiphu elishisayo lifaka amanzi okugqumisa ipayipi lensimbi kuqala.Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokukhetha, ihlanzwa nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride ne-zinc chloride exutshwe ne-aqueous solution tank, bese ithunyelwa ethangini elishisayo le-dip galvanizing.I-hot dip galvanizing inezinzuzo zokuhlanganisa iyunifomu, ukunamathela okuqinile nempilo ende yesevisi.Iningi lezinqubo eNyakatho zisebenzisa inqubo yokugoqeka ngokuqondile komchilo we-galvanized ukuze kwenezele i-zinc.I-matrix yepayipi lensimbi kanye nesixazululo se-plating esincibilikisiwe sinokuhlangana okuyinkimbinkimbi ngokomzimba namakhemikhali, okwenza ungqimba lwe-zinc iron alloy ukumelana nokubola olunesakhiwo esiqinile.Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi.Ngakho-ke, inokumelana nokugqwala okuqinile.
