Ukufaka i-hot-dip galvanizing kuyinqubo eyinhloko yokuvimbela ukugqwala nokugqwalaizigxobo zokukhanyisa zensimbi. Izinga kanye nobukhulu bengubo ye-zinc kunquma ngqo impilo yenkonzo yangaphandle yengongolo yokukhanya. Izinkampani eziningi zokwakha ubunjiniyela zokuthenga nokukhanyisa zivame ukungacaci ngezindinganiso zikazwelonke, ukuhlukaniswa kobukhulu, kanye nezidingo zokuzivumelanisa nezimo zesimo. Namuhla, ifektri yezibani ze-galvanized yangaphandle i-Tianxiang izochaza ngokuningiliziwe amazinga okusebenzisa izingodo zokukhanya zasemgwaqweni ze-HDG, amapharamitha wobukhulu bengubo ye-zinc yobukhulu obuhlukene bodonga, kanye nemininingwane yokukhetha yezigcawu zasogwini nezangaphakathi, okukusiza ugweme izingibe zengubo encane nezinto ezingezona ezijwayelekile.
I. Izindinganiso Zokusetshenziswa Ezijwayelekile Zezinsika Zezibani Zemigwaqo ze-HDG
Njengezinto eziyinhloko zokukhanyisa komasipala kanye nobunjiniyela bemigwaqo, ukuhlanganiswa kwe-zinc kwezinsika zokukhanya zasemgwaqweni ze-HDG kubalulekile ekunqumeni ukuvimbela ukugqwala nokugqwala kanye nokuphila kwesikhathi senkonzo. Amaphrojekthi asekhaya ngokuvamile alandela indinganiso kazwelonke ye-GB/T 13912-2022 ethi “Metallic Coatings – Izidingo Zobuchwepheshe kanye Nezindlela Zokuhlola Zokuhlanganiswa Kwensimbi Okushisayo”. Okwamanje, amaphrojekthi okuthumela kwamanye amazwe omasipala kanye nokuhweba kwamanye amazwe azobhekisela ezindinganisweni ezifanele ze-ISO zamazwe ngamazwe zokufaka i-galvanizing.
Indinganiso ifuna ngokusobala ukuthi lonke ipali lokukhanyisa lensimbi lisebenzise inqubo yokugaya ngokushisa komzimba wonke, okuvimbela kuphela ukufutha okungaphezulu noma ukwelashwa kokugaya ngokulinganisela. Ngemva kokukhuhla, ukususa ukugqwala, kanye nokugeleza, i-substrate yensimbi ifakwa ebhavini le-zinc elishisa kakhulu ukuze kwakheke ungqimba lwe-zinc oluhlanganiswe ngensimbi. Lolu ngqimba lunamathelana kakhulu futhi alususwa kalula, okwenza lufanelekele izindawo eziyinkimbinkimbi zangaphandle njengezinkambu ezivulekile, izindawo ezisogwini, kanye nezindawo ezinomswakama, ezinosawoti-alkali. Kuyisiqinisekiso esiyisisekelo sokuvikelwa kokugqwala kwezingodo zokukhanya zasemgwaqweni.
II. Izidingo Zokuhlukaniswa Kobukhulu Besendlalelo Esifakwe I-Hot-Dip Galvanized
1. Izindinganiso Zobukhulu Ezisekelwe Ekujiyeni Kodonga Lwezinsika
- Ubukhulu bodonga < 4mm: Ubukhulu obumaphakathi bengqimba ye-zinc obungaphansi kwama-55μm, kanye nobukhulu bendawo obungaphansi kwama-45μm. Isetshenziswa kakhulu ezinsikeni ezincane zegceke kanye nezinsikeni ezilula zokukhanya zasemgwaqweni ezingamamitha angu-3-5.
- Ubukhulu bodonga 4mm～6mm: Ubukhulu obumaphakathi bengqimba ye-zinc obungaphansi kuka-70μm, kanye nobukhulu bendawo okungenani obungu-55μm. Ngesibani somgwaqo esivamile esingamamitha angu-6-10.
- Ubukhulu Bodonga > 6mm: Isilinganiso Sokumboza Ngezinki okungenani okungu-85μm okungenani okungu-70μm. Kusebenza ekukhanyeni okuphezulu kwe-mast okungaphezu kwamamitha ayi-12, umgwaqo omkhulu kamasipala, izinsika zokukhanya zomgwaqo omkhulu.
2. Isidingo Esikhulayo Ezimweni Ezihlukahlukene Zokusetshenziswa
Imigwaqo evamile yasemadolobheni nasemaphandleni: Ubukhulu obujwayelekile bukazwelonke buyanele, futhi impilo yokusebenza iyiminyaka eyi-15-20.
Izindawo zokufutha usawoti ogwini, amapaki ezimboni amakhemikhali, izindawo ezinomswakama ophansi: ungqimba olufakwe i-hot-dip galvanized kufanele luqiniswe lube ngaphezu kuka-100μm ubukhulu obuphelele ukuze kuthuthukiswe ukumelana kwalo ne-salt spray kanye ne-acid/alkali corrosion futhi kuncishiswe i-oxidation kanye nokugqwala kwe-zinc coating.
III. Ukwamukelwa Kwekhwalithi Ye-Zinc Coating—Izidingo Eziphansi
1. Ikhwalithi Yokubukeka
Ubuso obufanayo nobubushelelezi, akukho galvanizing engaphelele, amabhamuza, ukuxebuka, amaqhubu namabala amnyama. Ama-weld, ama-port nama-flanges akufanele abe namakhona afile futhi angabi ne-galvanizing engaphelele.
2. Izinga Lokunamathela
Isembozo se-zinc akufanele siqhekeke noma siqhekeke ngesikhathi sokushaya kwesando kanye nokuhlolwa kokunqunywa okuphambene, futhi kufanele siboshwe ngokuqinile kwisisekelo sensimbi.
3. Indlela Yokuhlola
Ukuhlolwa kwesampula enamaphuzu amaningi kusetshenziswa igeyiji yobukhulu be-zinc coating. Izingxenye ezingaphezulu, eziphakathi, nezingezansi ze-pole kanye nesisekelo se-flange kumele zonke zihlangabezane nezinga elijwayelekile. Uma noma yikuphi ukulinganisa kwehluleka, lonke i-batch kumele lihlolwe kabusha futhi liphinde lisetshenzwe kabusha.
Ubukhulu besendlalelo se-hot-dip galvanized bunquma ngqo impilo yenkonzo yangaphandle yezigxobo zokukhanyisa zensimbi. Kokubili ukuthengwa kobunjiniyela kanye nokwenza ngokwezifiso komkhiqizi kumele kufane ngokuqinile nobukhulu be-galvanized obuhambisanayo ngokuya ngobukhulu bodonga obujwayelekile bukazwelonke.Ifektri yesibani se-lamp pole yangaphandleI-Tianxiang yenqaba ukusebenzisa i-galvanization encane engeyona ejwayelekile ukuqinisekisa ukusetshenziswa okuzinzile kwesikhathi eside kwamaphrojekthi okukhanyisa.
