Umbhobho wentsimbi emnyamayintsimbi engagqunywanga kwaye ikwabizwa ngokuba yintsimbi emnyama.Umbala omnyama uvela kwi-iron-oxide eyenziwe kumphezulu wayo ngexesha lokuvelisa.Xa umbhobho wensimbi wenziwa, i-black oxide scale ifom kumgangatho wayo ukuze inike ukugqitywa okubonakalayo kolu hlobo lombhobho.

Umbhobho wentsimbi owenziwe ngamachizayile ntsimbi egqunywe ngumaleko wentsimbi ye-zinc.Ngexesha lokufakwa kwe-galvanizing, isinyithi sintywiliselwa kwindawo yokuhlambela ye-zinc etyhidiweyo, iqinisekisa ukuba i-barrier barrier iyaqina, iyunifomu.Umbhobho we-galvanized ugqunywe ngezinto ze-zinc ukwenza umbhobho wentsimbi uxhathise ngakumbi kwi-corrosion.

Umahluko ngenkangeleko
Injongo ephambili yombhobho wensimbi emnyama kukuthwala ipropane okanye igesi yendalo kwizindlu zokuhlala kunye nezakhiwo zorhwebo.Umbhobho wenziwa ngaphandle komthungo, okwenza kube ngumbhobho ongcono wokuphatha igesi.Umbhobho wentsimbi omnyama ukwasetyenziselwa iinkqubo zokutshiza umlilo ngenxa yokuba unamandla okumelana nomlilo kunombhobho wegalvanized.Olona setyenziso luphambili lombhobho ofakwe igalvanized kukuhambisa amanzi kumakhaya nakwizakhiwo zorhwebo.I-zinc iphinda ithintele ukwakhiwa kwee-mineral deposits ezinokuvala umgca wamanzi.Umbhobho owenziwe ngamachiza udla ngokusetyenziswa njengezakhelo zesikafula ngenxa yokuxhathisa ukubola.

Umahluko kwiingxaki
I-zinc kumbhobho we-galvanized iyancipha ngokuhamba kwexesha, ivala umbhobho.I-flaking inokubangela ukuba umbhobho ugqabhuke.Ukusebenzisa umbhobho wegalvanized ukuthwala igesi kunokudala ingozi.Umbhobho wentsimbi emnyama, kwelinye icala, udleka lula kunombhobho owenziwe ngamazimba kwaye uvumela iiminerali ezivela emanzini ukuba zakheke ngaphakathi kuwo.
