Imibhobho yentsimbi eGqwethiweyo ekumgangatho oPhakamileyo yaseTshayina yeMisebenzi yoKwakha
Umbhobho owenziwe ngesinyithi oshushu-dip kukwenza ukuba isinyithi esinyibilikisiweyo siphendule kunye ne-matrix yentsimbi ukuvelisa umaleko we-alloy, ukwenzela ukuba i-matrix kunye ne-coating zidityaniswe.I-Hot-dip galvanizing kukuvuthela umbhobho wentsimbi kuqala.Ukuze kususwe i-iron oxide kumphezulu wombhobho wentsimbi, emva kokuchola, icocwa kwitanki nge-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye isisombululo esinamanzi esixubeneyo se-ammonium chloride kunye ne-zinc chloride, emva koko ithunyelwe kwi-In. itanki yokufaka idiphu eshushu.I-Hot-dip galvanizing ineenzuzo zokugquma okufanayo, ukubambelela okuqinileyo kunye nobomi obude benkonzo.I-matrix yombhobho wentsimbi etshisiweyo ediphu ingena kwi-complex physical and chemical reaction kunye nesisombululo se-plating esityhidiweyo ukwenza umaleko we-alloy we-zinc-iron onganyangekiyo kunye nesakhiwo esihlangeneyo.Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-matrix yombhobho wensimbi, ngoko ukuxhathisa kwayo kunamandla.
Umbhobho we-galvanized obandayo u-electro-galvanizing, kwaye inani le-galvanizing lincinci kakhulu, kuphela i-10-50g / m2, kwaye ukuxhathisa ukubola kwayo kubi kakhulu kunombhobho we-galvanized dip.Uninzi lwabavelisi bemibhobho ye-galvanized rhoqo abayisebenzisi i-electro-galvanization (i-cold plating) ukuze kuqinisekiswe umgangatho.Kuphela loo mashishini amancinci anezixhobo ezincinci kunye neziphelelwe lixesha asebenzisa i-electro-galvanization, kwaye ngokuqinisekileyo amaxabiso abo aphantsi kakhulu.UMphathiswa wezoKwakha ubhengeze ngokusemthethweni ukuba imibhobho ebandayo ene-galvanized technology isemva kufuneka isuswe, kwaye imibhobho enamanzi abandayo ayivumelekanga ukuba isetyenziswe njengemibhobho yamanzi kunye negesi.Uluhlu lwezinki lombhobho wensimbi obandayo luyi-electroplated layer, kwaye i-zinc layer ihlukaniswe kwi-matrix yombhobho wensimbi.I-zinc layer incinci, kwaye i-zinc layer ibambelela nje kwi-substrate yombhobho wensimbi kwaye kulula ukuwa.Ngoko ke, ukuxhathisa kwayo ku-corrosion kubi.Kwizindlu ezisandula ukwakhiwa, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yokuhambisa amanzi.
Imigangatho yesizwe kunye nemigangatho yobungakanani bemibhobho yegalvanized
I-GB/T3091-2015 Umbhobho wentsimbi odityanisiweyo wokuthutha ulwelo oluphantsi koxinzelelo
I-GB/T13793-2016 Umthungo oLungileyo woMbane wePipe weNtsimbi odityanisiweyo
I-GB/T21835-2008 ubungakanani bombhobho wentsimbi obudityanisiweyo kunye nobunzima beyunithi
Imibhobho yentsimbi eshushu-dip isetyenziswa ngokubanzi kulwakhiwo, oomatshini, imigodi yamalahle, imichiza, amandla ombane, izithuthi zikaloliwe, ishishini lemoto, oohola bendlela, iibhulorho, izitya, izibonelelo zemidlalo, oomatshini bezolimo, oomatshini bepetroleum, oomatshini bokukhangela, ukwakhiwa kwegreenhouse kunye nezinye. amashishini okuvelisa.
Imibhobho yentsimbi ekhandisiweyo ifakwe kwimibhobho yentsimbi ene-galvanized eshushu-dip okanye i-electro-galvanized layer phezu komhlaba.I-galvanizing inokunyusa ukuxhatshazwa kwe-corrosion yepayipi yensimbi kunye nokwandisa ubomi benkonzo.Umbhobho wegalvanized unoluhlu olubanzi lokusetyenziswa.Ukongeza kwimibhobho yokuhambisa amanzi, irhasi, i-oyile kunye nolunye ulwelo oluphantsi koxinzelelo oluphantsi, ikwasetyenziswa njengemibhobho ye-oyile yequla kunye nemibhobho yeoli kushishino lwepetroleum, ngakumbi imimandla yeoli ekude nonxweme, kunye nezifudumezi ze-oyile kunye nokuxinana kwimichiza yokupheka. izixhobo.Imibhobho yezipholileyo, izitshintshi zeoyile ehlanjwe ngamalahle, iimfumba zemibhobho yeebhulorho ze-trestle, kunye nemibhobho yezakhelo zenkxaso kwiitonela zemigodi, njl.njl.
