Umbhobho owenziwe ngegalvanized, ekwaziwa ngokuba ngumbhobho wentsimbi, ihlukaniswe ibe ziindidi ezimbini: i-hot-dip galvanizing kunye ne-electro-galvanizing. I-Hot-dip galvanizing inomaleko we-zinc engqindilili kwaye ineengenelo zokwaleka okufanayo, ukuncamathela okuqinileyo, kunye nobomi benkonzo ende. Iindleko zemibhobho ye-electro-galvanized iphantsi, umphezulu awululanga kakhulu, kwaye ukuxhathisa ukubola kubi kakhulu kunemibhobho ye-galvanized dip eshushu. Ukuze kuphuculwe ukuxhathisa kwe-corrosion yeepayipi zetsimbi, iibhobho zensimbi eziqhelekileyo zenziwe nge-galvanized. Imibhobho yentsimbi ekhuselweyo ihlulwe ibe ziindidi ezimbini: i-hot-dip galvanizing kunye ne-electro-galvanizing. I-Hot-dip galvanizing inomaleko ongqindilili we-zinc. Umbhobho odityanisiweyo ovuthelwa ngeoksijini: osetyenziswa njengombhobho wokwenza intsimbi evuthelwa ngeoksijini. Ngokuqhelekileyo, imibhobho yentsimbi edityanisiweyo encinci iyasetyenziswa. Ukuze kuthintelwe ukubola, ezinye kufuneka zifakwe ngokufanelekileyo i-aluminum.
(1)Imveliso ecocekileyo ekhethekileyo
Umbhobho we-galvanized wamkela inkqubo ye-sulfate electroplating ye-alloy ye-zinc-iron, oku kuthetha ukuba kukho i-perforations ngqo phakathi kweendlela zokuvelisa kunye nemigodi ngaphandle kokuthwala okanye ukuphuphuma kwesisombululo. Inkqubo nganye yenkqubo yokuvelisa iqulunqwe yinkqubo yokujikeleza. Izisombululo kwitanki nganye, oko kukuthi isisombululo se-asidi kunye ne-alkali, isisombululo se-electroplating, i-extraction light kunye nesisombululo se-passivation, njl., zihlaziywa kuphela kwaye azivuzi okanye zikhutshwe ngaphandle kwenkqubo. Umgca wemveliso unamatanki okucoca ama-5 kuphela, asebenzisa ukujikeleza. Sebenzisa kwakhona kwaye ukhuphe rhoqo, ngakumbi kwiinkqubo zokuvelisa ezingavelisi amanzi amdaka ngaphandle kokucoca emva kokudlula.
(2) Ubungcali bezixhobo zokucoca i-electroplating
I-electroplating yemibhobho ye-galvanized kunye ne-electroplating yeengcingo zobhedu zifana ne-electroplating eqhubekayo, kodwa izixhobo zokucoca zihlukile. Itanki yokucwenga iyilwe ngohlobo olubhityileyo lwemilo yocingo lwentsimbi. Umzimba wetanki mde, ubanzi kodwa awunzulu. Ngexesha le-electroplating, iingcingo zentsimbi zidlula emingxunyeni kwaye zisasazeke kwindawo yolwelo ngendlela echanekileyo, zigcina umgama phakathi kwazo. Nangona kunjalo, umbhobho we-galvanized wahlukile kwi-iron wire kuba uneempawu zayo ezizodwa kwaye izixhobo zetanki zinzima kakhulu. Umzimba wetanki uqulunqwe ngamalungu aphezulu nangaphantsi. Inxalenye ephezulu yitanki yokucoca kwaye inxalenye engezantsi yitanki yokugcina i-circulation circulation, eyenza i-trapezoid efana ne-tank body emxinwa phezulu kwaye ibanzi ezantsi. Kukho umjelo wokusebenza kombhobho we-galvanized electroplating kwitanki yokucoca. Kukho imingxunya emibini emazantsi etanki enxibelelana netanki yokugcina esezantsi, kwaye yenze inkqubo yokucoca isisombululo sokucoca ngempompo entywilayo. Ngoko ke, imibhobho ye-galvanized ifana ne-iron wire electroplating, kunye neengxenye ezicwecwe ziguquguqukayo. Nangona kunjalo, ngokungafaniyo nocingo lwentsimbi, isisombululo se-plating semibhobho yegalvanized nayo iyaguquguquka.
(3) Ukuphuculwa kwe-sulfate galvanizing
Iinzuzo ze-sulfate galvanizing kukuba ukusebenza kwangoku kuphezulu njenge-100% kunye nesantya sokubeka ngokukhawuleza, esingenakulinganiswa nezinye iinkqubo ze-galvanizing. Ngenxa yokuba icrystallization yokwambathisa ayilunganga ngokwaneleyo, isakhono sokusasazwa kunye nobuchule obunzulu bokucwenga buhlwempuzekile, ngoko kulungele kuphela imibhobho yokucoca kunye neengcingo ezinemilo yejometri elula. Inkqubo ye-sulfate electroplating zinc-iron alloy iphucula inkqubo ye-sulfate galvanizing yendabuko. Kuphela i-zinc sulfate yetyuwa ephambili igcinwa, kwaye amacandelo asele alahlwa. Isixa esifanelekileyo setyuwa yentsimbi yongezwa kwinkqubo entsha yokwenza i-zinc-iron alloy coating ukusuka kwi-original yentsimbi enye. Uhlenga-hlengiso ngokutsha lwenkqubo akuzisi phambili kuphela iingenelo zokusebenza okuphezulu kwangoku kunye nesantya sokubekwa ngokukhawuleza kwenkqubo yantlandlolo, kodwa kukwaphucula kakhulu isakhono sokusasazwa kunye nobuchule bokucwenga obunzulu. Ngaphambili, iinxalenye eziyinkimbinkimbi azikwazi ukugqithwa, kodwa ngoku zombini iindawo ezilula kunye neziyinkimbinkimbi zinokuthi zifakwe, kwaye ukusebenza okukhuselekileyo kukwa-3 ukuya kumaxesha angama-5 aphezulu kunentsimbi enye. Ukuziqhelanisa nokuvelisa kubonakalise ukuba xa kusetyenziselwa i-electroplating eqhubekayo yeengcingo kunye nemibhobho, iinkozo zokugquma zicolile kwaye ziqaqambile kunezo zakuqala, kwaye isantya sokubekwa siyakhawuleza. Ubunzima bokugquma bufikelela kwimfuno phakathi kwemizuzu emi-2 ukuya kwemi-3.
(4) Ukuguqulwa kwe-sulfate zinc plating
I-sulfate electroplating ye-zinc-iron alloy igcina kuphela i-zinc sulfate, ityuwa ephambili ye-sulfate zinc plating. Izinto eziseleyo ezifana ne-aluminium sulfate, i-alum (i-potassium aluminium sulfate), njl. Susa; kwizongezo ze-organic, yongeza umgubo wekhabhoni esebenzayo ukuyisusa nge-adsorption.
Uvavanyo ngabavelisi bemibhobho ye-galvanized baye babonisa ukuba i-aluminium sulfate kunye ne-potassium aluminium sulfate kunzima ukuyisusa ngokupheleleyo ngexesha elinye kwaye ibe nefuthe ekukhanyeni kwengubo, kodwa ayinzima kwaye inokukhutshwa ukuze isetyenziswe. Ngeli xesha, ukukhanya kwengubo kunokubuyiselwa ngonyango kunye nesisombululo. Yongeza isiqulatho esifunekayo ngokwenkqubo entsha ukugqiba inguqu.
Ukuba ufuna ukwazi iinkcukacha ezithe vetshe malunga nombhobho wentsimbi, nceda ukhululeke ukudibana nathi.
