Umbhobho wediphu oshushu
Inkcazelo emfutshane:
Umbhobho wediphu oshushu wamanzi, ukwenzela ukuba kuphuculwe ukuxhathisa umhlwa kombhobho wentsimbi, umbhobho wentsimbi jikelele ufakwe igalvanized.Imibhobho yentsimbi ekhuselweyo ihlulwe ibe yi-galvanizing eshushu-dip kunye ne-electro galvanizing.I-hot-dip galvanizing layer inzima, ixabiso le-electro galvanizing liphantsi, kwaye umphezulu awugudi kakhulu.
injongo
Imibhobho yentsimbi esetyenziselwa irhasi, i-greenhouse kunye nokufudumeza nayo iyimibhobho eyenziwe ngamagalvanized.Njengemibhobho yamanzi, imibhobho ye-galvanized ivelisa inani elikhulu lokugqwala kunye nomlinganiselo kwimibhobho.Amanzi atyheli awangcolisi kuphela izinto zococeko, kodwa adityaniswe neebhaktheriya ezizala kudonga lwangaphakathi olungaguqukiyo.Ukonakala kubangela ukuba umxholo wesinyithi esinzima emanzini uphakame kakhulu, nto leyo ebeka emngciphekweni impilo yabantu.Ngeminyaka yee-1960 kunye neyee-1970, amazwe aphuhlileyo ehlabathini aqalisa ukwenza imibhobho emitsha, yaye imibhobho eyenziwe ngamazimba yavalwa enye emva kwenye.Umphathiswa wezokwakha wase China kunye namanye amasebe amane kunye neekomishoni nazo ziyibeke yacaca into yokuba imibhobho yezitha yavalwa ukususela ngo-2000.
