Kuthira ma galvanizing otentha ndi njira yodziwika bwino yotetezera dzimbiri la zitsulo. Kumamiza zinthu zachitsulo mu madzi osungunuka a zinc kuti apange zinc-iron alloy wosanjikiza ndi zinc yeniyeni pamwamba pa chitsulo, motero kumateteza dzimbiri bwino. Njirayi imagwiritsidwa ntchito kwambiri pa zomangamanga, magalimoto, magetsi, kulumikizana ndi mafakitale ena kuti ateteze nyumba zachitsulo, mapaipi, zomangira, ndi zina zotero.
Njira zoyambira zoyeretsera galvanizing ndi izi:
Kuchotsa mafuta ndi kuyeretsa
Choyamba, pamwamba pa chitsulocho pamafunika kutsukidwa bwino kuti mafuta, dothi ndi zinthu zina zodetsa zichotsedwe. Izi nthawi zambiri zimachitika poika chitsulocho mu madzi amchere kapena acidic kenako n’kutsuka ndi madzi ozizira.
Chophimba cha Flux
Chitsulo chotsukidwacho chimamizidwa mu yankho la zinc ammonium la 30% pa kutentha kwa madigiri 65-80.°CCholinga cha gawoli ndikugwiritsa ntchito wosanjikiza wa flux kuti ithandize kuchotsa ma oxide pamwamba pa chitsulo ndikuwonetsetsa kuti zinc yosungunuka ikhoza kuchita bwino ndi chitsulocho.
Kukongoletsa
Chitsulocho chimamizidwa mu zinc yosungunuka pa kutentha kwa pafupifupi madigiri 450.°C. Nthawi yoviika nthawi zambiri imakhala mphindi 4-5, kutengera kukula ndi kutentha kwa chitsulocho. Pa nthawiyi, pamwamba pa chitsulocho pamachita zinthu mogwirizana ndi zinc yosungunuka.
Kuziziritsa
Pambuyo poika galvanizing yotentha, chitsulocho chiyenera kuziziritsidwa.Kuziziritsa mpweya mwachilengedwe kapena kuzimitsa mwachangu kungasankhidwe, ndipo njira yeniyeniyo imadalira zofunikira zomaliza za chinthucho..
Kuthira galvanizing ndi njira yabwino yothanirana ndi dzimbiri pa chitsulo, zomwe zimapereka maubwino akuluakulu:
●Mtengo wotsika: Mtengo woyambira komanso wa nthawi yayitali wa galvanizing wothira m'madzi otentha nthawi zambiri umakhala wotsika poyerekeza ndi zokutira zina zotsutsana ndi dzimbiri, zomwe zimapangitsa kuti ikhale chisankho chotsika mtengo.
●Moyo wautali kwambiri wa ntchito: Chophimba cha galvanized chimatha kuteteza chitsulocho mosalekeza kwa zaka zoposa 50 ndikuletsa dzimbiri.
●Kusamalira kochepa kumafunika: Popeza chophimba cha galvanized chimadzisamalira chokha komanso chokhuthala, chimakhala ndi ndalama zochepa zosamalira komanso nthawi yayitali yogwirira ntchito.
●Zimateteza malo owonongeka okha: Chophimbacho cha galvanized chimapereka chitetezo chodzipereka, ndipo malo ang'onoang'ono owonongeka safuna kukonzanso kwina.
●Chitetezo chokwanira komanso chokwanira: Kuthira ma galvanizing otentha kumatsimikizira kuti ziwalo zonse, kuphatikizapo malo ovuta kufikako, zatetezedwa mokwanira.
●Kuwunika kosavuta: Mkhalidwe wa chophimba chopangidwa ndi galvanized ukhoza kuyesedwa powunika mosavuta.
●Kukhazikitsa mwachangu:Zinthu zopangidwa ndi chitsulo chotenthedwa ndi magalasi zimakhala zokonzeka kugwiritsidwa ntchito zikafika pamalo ogwirira ntchito, popanda kukonzekera kwina kapena kuyang'ana komwe kukufunika.
● Kugwiritsa ntchito mwachangu chophimba chonse: Njira yothira ma galvanizing m'madzi otentha ndi yachangu ndipo sikhudzidwa ndi nyengo, zomwe zimapangitsa kuti zinthu zisinthe mwachangu.
Ubwino uwu umapangitsa kuti galvanizing yotenthedwa ikhale chisankho chabwino kwambiri choteteza dzimbiri la chitsulo, zomwe sizimangowonjezera moyo wa ntchito ndi magwiridwe antchito a chitsulo, komanso zimachepetsa ndalama zonse ndi ntchito yokonza.
Malo owonekera a zolumikizira kumapeto (kuphatikiza nkhope za flange) zaMapayipi opopera ndi otulutsira mafuta a CDSRZimatetezedwa ndi ma galvanizing otenthedwa motsatira EN ISO 1461, ku dzimbiri lomwe limayambitsidwa ndi madzi a m'nyanja, nkhungu yamchere ndi njira yotumizira. Pamene makampani opanga mafuta ndi gasi akupitilizabe kufunafuna chitukuko chokhazikika, kugwiritsa ntchito ukadaulo wa ma galvanizing otenthedwa sikuti kumangowonjezera kukana dzimbiri kwa zida ndikuwonjezera nthawi yogwirira ntchito, komanso kumachepetsa kugwiritsa ntchito zinthu ndi zinyalala mwa kuchepetsa kuchuluka kwa zida zomwe zimasinthidwa chifukwa cha dzimbiri.
