Umbhobho wegalvanized ngumbhobho wensimbi kunye ne-hot-dip okanye i-electroplated coating phezu kwayo.I-galvanizing inokunyusa ukuxhatshazwa kwe-corrosion yeepayipi zensimbi kunye nokwandisa ubomi babo benkonzo.Eli nqaku lazisa iimpawu zenkqubo yemibhobho eyenziwe ngegalvanized:
1. Ukuphuculwa kweSulfate Zinc Plating
Inzuzo enkulu ye-sulfate zinc plating kukusebenza kwayo ngoku ukuya kuthi ga kwi-100% kunye nesantya sokubeka ngokukhawuleza, esingenakulinganiswa nezinye iinkqubo ze-zinc plating.Ngenxa yokungonelanga kwecrystallinity yokwambathisa, ukusasazwa kakubi kunye nobuchule obunzulu bokucwenga, kulungele kuphela i-electroplating yemibhobho kunye neengcingo ezinemilo yejometri elula.Inkqubo yokufakwa kwe-sulfate ye-zinc yendabuko iphuculwe yinkqubo ye-sulfate zinc plating.Kuphela ityuwa ephambili i-Zinc sulfate igcinwa, kwaye amanye amacandelo alahlwa.Yongeza isixa esifanelekileyo setyuwa yentsimbi kwifomula entsha yenkqubo ukwenza intsimbi yentsimbi ekwalekayo ukusuka kwintsimbi yokuqala yokwaleka.Uhlenga-hlengiso lwenkqubo alukhuthazi nje kuphela iingenelo zokusebenza okuphezulu kwangoku kunye nesantya sokubekwa ngokukhawuleza kwenkqubo yantlandlolo, kodwa kwakhona kuphucula kakhulu isakhono sokusasazwa kunye nobuchule obunzulu bokucwenga.Ngaphambili, iindawo eziyinkimbinkimbi azikwazi ukugqithwa, kodwa ngoku zombini iindawo ezilula kunye neziyinkimbinkimbi zinokuthi zifakwe, kwaye ukusebenza kokukhusela kuphuculwe ngamaxesha angama-3-5 xa kuthelekiswa nezinyithi enye.Ukuziqhelanisa nemveliso kubonakalise ukuba kwi-electroplating eqhubekayo yeengcingo kunye nemibhobho, ubungakanani beenkozo zotyatyazo buhle, buqaqambile, kwaye isantya sokubekwa siyakhawuleza kunangaphambili.Ubunzima bokugquma buhlangabezana neemfuno ngaphakathi kwemizuzu emi-2-3.
2. Ukuguqulwa kweSulfate Zinc Plating
Kuphela i-Zinc sulfate, ityuwa ephambili ye-sulfate zinc plating, igcinwe kwi-sulfate electro galvanized iron alloy.Amanye amacandelo afana ne-Aluminium sulfate kunye ne-alum (i-Potassium alum) inokususwa ngokudibanisa i-sodium hydroxide ukwenza i-insoluble hydroxide precipitation ngexesha lokunyangwa kwesisombululo se-plating;Kwizongezo ze-organic, i-powdered carbon activated yongezwa kwi-adsorption kunye nokususwa.Uvavanyo lubonisa ukuba kunzima ukususa ngokupheleleyo i-Aluminium sulfate kunye ne-Potassium alum ngexesha elinye, elinempembelelo ekukhanyeni kwengubo, kodwa ayinzima, kwaye ingadliwa nayo.Ngeli xesha, ukukhanya kwengubo kunokubuyiselwa kwisisombululo ngonyango, kwaye ukuguqulwa kunokugqitywa ngokufaka umxholo wamacandelo afunwa yinkqubo entsha.
3. Isantya sokubeka ngokukhawuleza kunye nokusebenza okugqwesileyo kokukhusela
Ukusebenza kwangoku kwenkqubo ye-sulfate electroplating ye-zinc iron alloy iphezulu njenge-100%, kwaye izinga lokubeka lingenakulinganiswa kuyo nayiphi na inkqubo ye-galvanizing.Isantya sokusebenza sombhobho ococekileyo ngu-8-12 m / min, kunye nobukhulu obuqhelekileyo bokugquma ngu-2 m / min, okunzima ukufezekisa kwi-galvanizing eqhubekayo.Ukwaleka kuqaqambile, kuthambile, kwaye kuthandeka emehlweni.Ivavanywe ngokwemigangatho yesizwe ye-GB/T10125 "Uvavanyo lwe-Atmosphere ye-Artificial - Uvavanyo lwe-Salt Spray Test" indlela, iiyure ze-72, i-coating i-intact kwaye ayitshintshi;Emva kweeyure ezingama-96, intwana yomhlwa emhlophe yavela kumphezulu wokwaleka.
4. Imveliso ecocekileyo ekhethekileyo
Umbhobho wagalvanized wamkela inkqubo ye-sulfate electroplating galvanized iron alloy, ebonakala ngokugqobhoza phakathi kwendawo yokubeka umgca wemveliso kunye ne-slot, ngaphandle kokungena kwesisombululo okanye ukuphuphuma.Inkqubo nganye kwinkqubo yokuvelisa iqulethe inkqubo yokujikeleza.Izisombululo kwitanki nganye, kubandakanywa isisombululo se-acid-base, isisombululo se-electroplating, ukukhutshwa kunye nesisombululo se-passivation, sihlaziywa kuphela kwaye sisetyenziswe kwakhona ngaphandle kokuvuza okanye ukukhutshwa ngaphandle kwenkqubo.Umgca wemveliso unamatanki okucoca ama-5 kuphela, akhutshwa rhoqo ngokusetyenziswa kwakhona kwe-cyclic, ngokukodwa kwinkqubo yokuvelisa apho kungekho manzi amdaka avelisiweyo emva kokudlula ngaphandle kokucoca.
5. Ubunjani bezixhobo zokufaka i-electroplating
I-electroplating yemibhobho ye-galvanized, njenge-electroplating yocingo, yeyokuba i-electroplating eqhubekayo, kodwa izixhobo ezisetyenziselwa i-electroplating zahlukile.Umjelo wokwaleka owenzelwe ucingo lwentsimbi kunye neempawu zawo ezibhityileyo, umzimba wegroove mde kwaye ubanzi kodwa awunzulu.Ngexesha le-electroplating, ucingo lwentsimbi luphuma emngxunyeni ngendlela echanekileyo
