* UKUGALAZA
Umbhobho owenziwe ngesinyithi oshushu-dip kukwenza isinyithi esinyibilikisiweyo sisebenze kunye ne-matrix yentsimbi ukuvelisa umaleko wealloyi, ngaloo ndlela udibanisa imatrix kunye nokwaleka. I-asidi yediphu eshushu ihlamba umbhobho wentsimbi ukuze isuse i-iron oxide kumphezulu wombhobho wentsimbi. Emva kokuhlamba i-asidi, ihlanjululwa kwitanki nge-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye umxube we-ammonium chloride kunye ne-zinc chloride isisombululo se-aqueous, kwaye emva koko ithunyelwe kwi-bath-dip galvanizing bath.
I-Hot-dip galvanizing ineengenelo zokwaleka okufanayo, ukuncamathela okuqinileyo, ukuxhathisa okuhle kokubola, kunye nobomi benkonzo ende. Ngokukodwa kwiindawo ezinobunzima, ezifana nemvula, imvula, imvula ye-asidi, ityuwa yokutshiza kunye nezinye iindawo, ukusebenza kwe-hot-dip galvanizing kubonakala ngakumbi. I-substrate yentsimbi kunye nesisombululo se-plating esityhidiweyo sihlangabezana nobunzima bomzimba kunye neekhemikhali ukuze zenze umaleko we-zinc-iron alloy alloy-resistant kunye nesakhiwo esiqinileyo. Umaleko we-alloy, umaleko we-zinc ococekileyo, kunye ne-steel substrate zidityanisiwe. Ngoko ke, inokumelana ne-corrosion enamandla.
1. Ukulinganisa okufanayo kwengubo: Umbhobho wensimbi awuyi kujika obomvu (umbala wobhedu) emva kokucwiliswa kwisisombululo se-sulfate yethusi ngamaxesha angama-5 alandelelanayo.
2. Umgangatho womphezulu: Umphezulu wombhobho wentsimbi uya kuba nomaleko opheleleyo wegalvanized, kwaye akusayi kubakho mabala amnyama namaqamza angagqunywanga. Ivumelekile ukuba ibe nomphezulu orhabaxa kancinane kunye namaqhuqhuva e-zinc asekuhlaleni akhoyo.
