Ipayipi eliphehliwe yipayipi lensimbi eline-hot-dip noma i-electroplated coating phezu kwayo.I-galvanizing ingakhuphula ukumelana nokugqwala kwamapayipi ensimbi futhi yandise impilo yabo yesevisi.Lesi sihloko sethula izici zenqubo yamapayipi athathiwe:
1. Ukwenziwa ngcono kweSulfate Zinc Plating
Inzuzo enkulu ye-sulfate zinc plating ukusebenza kwayo kwamanje okufika ku-100% kanye nezinga lokubeka ngokushesha, elingenakuqhathaniswa nezinye izinqubo zokufaka i-zinc.Ngenxa ye-crystallinity enganele ye-coating, ukuhlakazeka okungalungile kanye nekhono lokucwenga elijulile, ifaneleka kuphela i-electroplating yamapayipi nezintambo ezinobunjwa obulula bejometri.Inqubo yendabuko ye-sulfate zinc plating yenziwa kahle yinqubo ye-sulfate zinc plating.Kuphela usawoti oyinhloko I-Zinc sulfate igcinwa, futhi ezinye izingxenye ziyalahlwa.Engeza inani elifanele likasawoti wensimbi kufomula yenqubo entsha ukuze wakhe ingxube ye-zinc iron alloy enamathela embotsheni yokuqala yensimbi eyodwa.Ukuhlelwa kabusha kwenqubo akuthuthukisi nje kuphela izinzuzo zokusebenza kahle kwamanje okuphezulu kanye nezinga lokubeka ngokushesha lenqubo yasekuqaleni, kodwa futhi kuthuthukisa kakhulu ikhono lokuhlakazeka kanye nekhono lokucwebeza elijulile.Esikhathini esidlule, izingxenye eziyinkimbinkimbi azikwazanga ukugqitshwa, kodwa manje zombili izingxenye ezilula neziyinkimbinkimbi zingafakwa, futhi ukusebenza kokuzivikela kuthuthukiswa izikhathi ezingu-3-5 uma kuqhathaniswa nezinsimbi ezilodwa.Ukuzijwayeza ukukhiqiza kufakazele ukuthi ekufakweni kwe-electroplating okuqhubekayo kwezintambo namapayipi, usayizi wokusanhlamvu we-coating uyacoleka, uyakhanya, futhi izinga lokubeka liyashesha kunangaphambili.Ugqinsi lwe-coating luhlangabezana nezidingo ngaphakathi kwemizuzu engu-2-3.
2. Ukuguqulwa kweSulfate Zinc Plating
I-Zinc sulfate kuphela, usawoti oyinhloko we-sulfate zinc plating, egcinwa ku-sulfate electro galvanized iron alloy.Ezinye izakhi ezifana ne-Aluminium sulfate kanye ne-alum (i-Potassium alum) ingasuswa ngokungeza i-sodium hydroxide ukuze yenze imvula ye-hydroxide enganyibiliki ngesikhathi sokwelashwa kwesisombululo sokucwenga;Ukuze uthole izithasiselo eziphilayo, ikhabhoni ecushiwe eyimpuphu yengezwa ukuze kukhangiswe futhi kususwe.Ukuhlolwa kubonisa ukuthi kunzima ukususa ngokuphelele i-Aluminium sulfate ne-Potassium alum ngesikhathi esisodwa, okunomthelela ekukhanyeni kwe-coating, kodwa akuyona into engathi sína, futhi ingadliwa nayo.Ngalesi sikhathi, ukukhanya kokugqoka kungabuyiselwa kwisixazululo ngokusebenzisa ukwelashwa, futhi ukuguqulwa kungaqedwa ngokungeza okuqukethwe kwezingxenye ezidingekayo ngenqubo entsha.
3. Izinga lokubeka ngokushesha kanye nokusebenza okuhle kakhulu kokuvikela
Ukusebenza kahle kwamanje kwenqubo ye-sulfate electroplating iron alloy iphezulu njengo-100%, futhi izinga lokubeka alinakuqhathaniswa kunoma iyiphi inqubo yokufaka ama-galvanizing.Isivinini sokusebenza se-tube enhle singama-8-12 m / min, futhi ubukhulu bokugqoka obuphakathi buyi-2 m / min, okunzima ukufeza ekuqhumeni okuqhubekayo.Ukwembeswa kugqamile, kuthambile futhi kuyajabulisa emehlweni.Ihlolwe ngokwendlela kazwelonke ejwayelekile ye-GB/T10125 "Artificial Atmosphere Test - Salt Spray Test", amahora angama-72, ukumbozwa kuphelele futhi akushintshile;Ngemva kwamahora angu-96, isamba esincane sokugqwala esimhlophe savela ebusweni bengubo.
4. Ukukhiqizwa okuhlanzekile okuyingqayizivele
Ipayipi elinothayela lamukela inqubo ye-sulfate electroplating galvanized iron alloy, ebonakala ngokubhoboza phakathi kwesikhala somugqa wokukhiqiza nendawo, ngaphandle kokungena kwesixazululo noma ukuchichima.Inqubo ngayinye ohlelweni lokukhiqiza iqukethe uhlelo lokujikeleza.Izisombululo ethangini ngalinye, okuhlanganisa isixazululo se-acid-base, isixazululo se-electroplating, isixazululo sokukhipha kanye ne-passivation, zigaywa kabusha futhi ziphinde zisetshenziswe ngaphandle kokuvuza noma ukukhishelwa ngaphandle kwesistimu.Ulayini wokukhiqiza unamathangi okuhlanza angu-5 kuphela, akhishwa njalo ngokuphinda asetshenziswe nge-cyclic, ikakhulukazi ohlelweni lokukhiqiza lapho kungekho khona amanzi angcolile akhiqizwa ngemva kokudlula ngaphandle kokuhlanza.
5. Ubunjalo bemishini ye-electroplating
I-electroplating yamapayipi athathiwe, njengokufakwa kwe-electroplating kocingo, kungokwe-electroplating eqhubekayo, kodwa okokusebenza okusetshenziselwa i-electroplating kuhlukile.I-plating groove edizayinelwe intambo yensimbi enezici zayo ezicijile ezacile, umzimba we-groove mude futhi ubanzi kodwa awushoni.Ngesikhathi se-electroplating, ucingo lwensimbi luphuma emgodini ngendlela eqondile
