Imibhobho yentsimbizahlulwe ngokwemibhobho yentsimbi ebandayo kunye nemibhobho yentsimbi enezinki eshushu.Imibhobho yentsimbi ebandayo iye yavalwa.Ngeminyaka yoo-1960 noo-1970, amazwe aphuhlileyo ehlabathini aqalisa ukuphuhlisa iindidi ezintsha zemibhobho kwaye ngokuthe ngcembe avala imibhobho eyenziwe ngamazi.Abaphathiswa abane kunye neekomishoni eziquka i-Ofisi yoLwakhiwo lwase-China nabo bakhuphe uxwebhu oluchaza ukuba imibhobho yegalvanized ivaliwe ukuba isetyenziswe njengemibhobho yokuhambisa amanzi ukususela ngo-2000. imibhobho kwezinye iindawo isebenzisa imibhobho enamazinki.Imibhobho yentsimbi etshisiweyo eshushu-dip inoluhlu olubanzi lwezicelo ekukhuseleni umlilo, amandla kunye neendlela ezinkulu.
Usetyenziso
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.
Umbhobho wensimbi owenziwe ngesinyithi ngumbhobho wensimbi odibeneyo kunye ne-galvanized eshushu-dip okanye i-electro-galvanized layer phezu komhlaba.I-galvanizing inokunyusa ukuxhatshazwa kwe-corrosion yeepayipi zensimbi kunye nokwandisa ubomi benkonzo.Imibhobho yegalvanized isetyenziswa ngokubanzi.Ukongeza ekusetyenzisweni njengemibhobho yoxinzelelo olusezantsi olunje ngamanzi, irhasi, kunye neoyile, ikwasetyenziswa njengemibhobho yeoyile yequla kunye nemibhobho yeoli kushishino lwepetroleum, ngakumbi kumasimi eoyile akude nonxweme, kunye nezifudumezi zeoyile kunye neecondenser. kwizixhobo zokupheka iikhemikhali.Imibhobho yezipholileyo, i-distillation yamalahle yokuhlamba ioyile, kunye nemibhobho yeemfumba ze-trestle, iifreyimu ezixhasayo kwiitonela zasemigodini, njl.
Intshayelelo eneenkcukacha
Idiphu eshushuumbhobho owenziwe igalvanized
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.Idiphu eshushuumbhobho wentsimbii-substrate ifumana ukuphendulwa komzimba kunye neekhemikhali eziyinkimbinkimbi kunye nesisombululo esityhidiweyo se-plating ukwenza i-zinc-iron alloy layer ye-corrosion kunye nesakhiwo esihlangeneyo.Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-substrate yombhobho wensimbi, ngoko inokumelana nokugqwala okuqinileyo.
Umbhobho obandayo wamazinki
Umbhobho obandayo we-galvanized i-electro-galvanized, kwaye inani le-galvanized lincinci kakhulu, kuphela i-10-50g / m2.Ukumelana nomhlwa kwayo kwahluke kakhulu kunombhobho wegalvanized wediphu eshushu.Ukuze kuqinisekiswe umgangatho, abaninzi abavelisi bemibhobho ye-galvanized rhoqo abayisebenzisi i-electro-galvanized (i-cold plating).Kuphela loo mashishini amancinci anezixhobo eziphelelwe lixesha asebenzisa i-electrogalvanizing, kwaye ngokuqinisekileyo amaxabiso abo aphantsi.UMphathiswa wezoKwakha ukhuphe ngokusemthethweni umyalelo wokuphelisa imibhobho ebandayo enezitha ezinobuchwephesha obuphelelwe lixesha, kwaye ingasebenzisi imibhobho ebandayo enamazinki kwimibhobho yamanzi nerhasi.Uluhlu lwezinki lombhobho wensimbi obandayo luyi-electroplating layer, kwaye i-zinc layer ixhomekeke ngokuzimeleyo kunye ne-substrate yombhobho wensimbi.I-zinc layer incinci, kwaye i-zinc layer ibambelela nje kwi-substrate yombhobho wensimbi kwaye kulula ukuwa.Ke ngoko, ukuxhathisa kwayo kukonakala.Kwizindlu ezisanda kwakhiwa, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yokuhambisa amanzi.
