Umbhobho wentsimbi ogqunywe ngeplastiki:
Umbhobho wensimbi owenziwe ngeplastiki luhlobo olutsha lombhobho oluhlaza kunye nokusingqongileyo, kwaye iimpawu zayo ezithile zingenza intandokazi entsha kwishishini lombhobho kwiminyaka nje elishumi.Okokuqala, kumbono wabarhwebi, kungakhathaliseki ukuba ngumbhobho weplastiki okanye umbhobho wensimbi, akukho mntu uya kugxininisa kwizinto ezingenanzuzo kwakhona ngaphandle kweenzuzo ezininzi.Ngoko ke, oku kwakhona Isizathu esikhulu sophuhliso olukhawulezayo lwemibhobho yensimbi efakwe ngeplastiki.Okwesibini, kumbono womthengi, nokuba ngokweempawu zemveliso okanye imisebenzi yesicelo, xa kuthelekiswa nemibhobho yeplastiki kunye nemibhobho yensimbi ene-galvanized, abathengi bakhetha ixabiso lesicelo elilethwe ngamapayipi ensimbi eplastiki.Umgangatho wokuphunyezwa kwenkqubo yokutshiza umlilo unikezelo lwamanzi iimveliso zemibhobho yentsimbi ehlanganiswe ngeplastiki "yinkqubo yokutshiza ngokuzenzekelayo inkqubo yokucima umlilo efakwe umbhobho wensimbi".Imveliso enexabiso eliphantsi iphucula kakhulu ixabiso lokusetyenziswa kwenkqubo, kwaye le mveliso yandisa unikezelo lwamanzi omlilo kunye nenkqubo yokutshiza ngokuzenzekelayo.ubomi benkonzo.
Imibhobho yentsimbi:
Imibhobho yentsimbi yahlulwe yaba yimibhobho yentsimbi ebandayo kunye nemibhobho yentsimbi eshushu.Imibhobho yentsimbi ebandayo iye yavalwa.Umbhobho owenziwe ngesinyithi oshushu-dip kukwenza isinyithi esinyibilikisiweyo sisebenze kunye ne-matrix yentsimbi ukuvelisa umaleko we-alloy, ukuze i-matrix kunye nokwaleka zidityaniswe.I-Hot-dip galvanizing kukuvuthela umbhobho wentsimbi kuqala.Ukuze ukususa i-iron oxide kumphezulu wombhobho wentsimbi, emva kokuchola, icocwa kwitanki ye-ammonium chloride okanye i-zinc chloride isisombululo esinamanzi okanye isisombululo esinamanzi esixutywe se-ammonium chloride kunye ne-zinc chloride, kwaye emva koko ithunyelwe Ibhafu yediphu eshushu.I-Hot-dip galvanizing ineenzuzo zokugquma okufanayo, ukubambelela okuqinileyo kunye nobomi obude benkonzo.I-substrate yentsimbi yombhobho wentsimbi eshushu-dip ingena kwi-complex physical and chemical reactions kunye nesisombululo esinyibilikisiweyo sokucwenga ukwenza umaleko we-alloy we-zinc-iron onganyangekiyo kunye nesakhiwo esihlangeneyo.Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-substrate yombhobho wensimbi, ngoko inokumelana nokugqwala okuqinileyo.Imibhobho ye-galvanized ye-Hot-dip inoluhlu olubanzi lwezicelo ekukhuseleni umlilo, amandla kunye neendlela ezinkulu.
