I-hot-dip galvanizing yindlela eqhelekileyo yokukhusela ukugqwala kwesinyithi. Ifaka iimveliso zentsimbi kulwelo lwezinc olunyibilikisiweyo ukuze lwenze umaleko we-zinc-iron alloy kunye nomaleko we-zinc ococekileyo phezu komphezulu wesinyithi, ngaloo ndlela ibonelela ngokhuseleko olufanelekileyo lokugqwala. Le ndlela isetyenziswa kakhulu kulwakhiwo, kwiimoto, kumbane, kunxibelelwano nakwamanye amashishini ukukhusela izakhiwo zentsimbi, imibhobho, izibophelelo, njl.njl.
Amanyathelo asisiseko enkqubo yokugaya i-hot-dip ngala alandelayo:
Ukususa amafutha kunye nokucoca
Umphezulu wentsimbi kufuneka uqale ucocwe kakuhle ukuze kususwe amafutha, ukungcola kunye nezinye izinto ezingcolileyo. Oku kudla ngokwenziwa ngokuntywilisela intsimbi kwisisombululo se-alkaline okanye se-asidi kulandele ukuhlamba ngamanzi abandayo.
Ukwaleka kweFlux
Intsimbi ecociweyo ifakwa kwisisombululo se-30% se-zinc ammonium kwi-65-80°CInjongo yale nyathelo kukufaka umaleko we-flux ukunceda ukususa ii-oxides kumphezulu wentsimbi nokuqinisekisa ukuba i-zinc enyibilikisiweyo inokusabela ngcono kwintsimbi.
Ukugaya nge-galvanizing
Intsimbi intywiliselwa kwi-zinc enyibilikisiweyo kubushushu obumalunga nama-450°C. Ixesha lokuntywiliselwa lidla ngokuba yimizuzu emi-4-5, kuxhomekeke kubukhulu kunye nobushushu obuphantsi kwentsimbi. Ngexesha lale nkqubo, umphezulu wentsimbi usabela ngokwekhemikhali kwi-zinc enyibilikisiweyo.
Ukupholisa
Emva kokuntywila nge-hot-dip, intsimbi kufuneka ipholiswe.Ukupholisa umoya wendalo okanye ukupholisa ngokukhawuleza ngokucima kunokukhethwa, kwaye indlela ethile ixhomekeke kwiimfuno zokugqibela zemveliso..
I-hot-dip galvanizing yindlela esebenzayo yokulwa nokugqwala kwentsimbi, enika iingenelo ezibalulekileyo:
●Ixabiso eliphantsi: Iindleko zokuqala nezexesha elide zokufaka i-hot-dip galvanizing zihlala ziphantsi kunezinye iingubo ezilwa nokugqwala, nto leyo eyenza ukuba kube lukhetho olufikelelekayo.
●Ubomi benkonzo obude kakhulu: Ingubo egqunyiweyo ingakhusela intsimbi ngokuqhubekayo kangangeminyaka engaphezu kwama-50 kwaye imelane ngempumelelo nokugqwala.
●Kufuneka ulondolozo oluncinci: Ekubeni i-coating ye-galvanized izigcina ikwimeko entle kwaye ityebile, ineendleko eziphantsi zokugcinwa kwayo kwaye iphila ixesha elide.
●Zikhusela ngokuzenzekelayo iindawo ezonakeleyo: Ingubo egqunyiweyo inika ukhuseleko lokuzincama, kwaye iindawo ezincinci zomonakalo azidingi ukulungiswa okongezelelweyo.
●Ukhuseleko olupheleleyo nolupheleleyo: Ukufakwa kwe-hot-dip kuqinisekisa ukuba zonke iindawo, kuquka neendawo ezingenakufikeleleka lula, zikhuselekile ngokupheleleyo.
●Kulula ukuyihlola: Imeko yokwaleka nge-galvanized ingavavanywa ngokuhlola okubonakalayo.
●Ufakelo olukhawulezileyo:Iimveliso zentsimbi egqunywe nge-hot-dip zilungele ukusetyenziswa xa zifika kwindawo yokusebenza, akukho mfuneko yokulungisa umphezulu okanye yokuhlola okongezelelweyo.
● Ukusetyenziswa ngokukhawuleza kwengubo epheleleyo: Inkqubo yokugalela i-hot-dip iyakhawuleza kwaye ayichaphazeleki yimozulu, nto leyo eqinisekisa ukuguquka ngokukhawuleza.
Ezi nzuzo zenza i-hot-dip galvanizing ibe lukhetho olufanelekileyo lokukhusela ukugqwala kwentsimbi, okungaphuculi nje kuphela ubomi benkonzo kunye nokusebenza kwentsimbi, kodwa kunciphisa iindleko zizonke kunye nomsebenzi wokulungisa.
Imiphezulu eveziweyo yezinto ezifakelweyo ekupheleni (kuquka ubuso beflange) yeIipayipi zokufunxa kunye nokukhupha ioyile ye-CDSRzikhuselwe yi-hot-dip galvanizing ngokuhambelana ne-EN ISO 1461, kwi-corrosion ebangelwa ngamanzi olwandle, inkungu yetyuwa kunye ne-transmission medium. Njengoko ishishini leoyile negesi liqhubeka nokuqhubela phambili uphuhliso oluzinzileyo, ukusetyenziswa kwetekhnoloji ye-hot-dip galvanizing akuphuculi nje kuphela ukumelana nokugqwala kwezixhobo kwaye kwandisa ubomi benkonzo yazo, kodwa kunciphisa ngokungathanga ngqo ukusetyenziswa kwezixhobo kunye nokuveliswa kwenkunkuma ngokunciphisa amaxesha okutshintshwa kwezixhobo ngenxa yokugqwala.
