Ubuhle bamathreyi ekhebula ashisayo adiphu

I-aUbuhle be-hot-dip galvanizedamathreyi ekhebula

I-Hot-dipothayelaithreyi lekhebula ziyizinhlobo ezivamile zeikhebulaiziteshi, ezenziwe ngamapuleti ensimbi abandayo ngeidiphu elishisayo lifakwe insimbiinqubo yangaphezulu, futhi yakhiwe izingxenye eziqondile ze-slotted,ithileyi or uhlobo lwesitebhisiithreyi lekhebula,ugqoko wekhebula ugqoko,ithreyi lekhebula elinezimbobo, njll.

Izinzuzo ze-hot-dip galvanizedukunqanda ikhebula:izakhiwo ezinhle zokulwa nokugqwala, impilo ende yenkonzo, ukwenziwa kwezimboni okuphezulu kokukhiqiza kanye nekhwalithi ezinzile.Ngakho-ke, isetshenziswa ezindaweni eziningi ezingaphandle ezingaphansi kokugqwala okukhulu komkhathi futhi azinakekelwa kalula.

1. Ngongqimba oluqinile lwe-zinc olumboze ingaphezulu lensimbi, lungagwema ukuthintana phakathi kwe-substrate yensimbi nanoma yisiphi isixazululo esonakalisayo futhi ivikele i-substrate yensimbi ekugqwaleni.Ngokwesimo sezulu esijwayelekile, ungqimba lwe-zinc lwakha indawo encane kakhulu futhi eminyene ye-zinc oxide, okunzima ukuyihlakaza emanzini, ngakho-ke inomphumela othile wokuvikela ku-substrate yensimbi.

2. Nge-iron-zinc alloy layer, ingabonisa ukumelana nokugqwala okuhle emkhathini wesifutho sikasawoti sasolwandle kanye nomkhathi wezimboni.

3. Ukubopha okuqinile, i-zinc nensimbi kuncibilika ngokufanayo futhi kunokumelana okuqinile nokugqokwa.

4. I-Zinc ine-ductility enhle, ngoba ungqimba lwalo lwe-alloy lunamathele ngokuqinile esisekelweni sensimbi, ngakho-ke izingxenye ezishisayo ze-galvanized zingabanda, zigoqwe, zidonswe, zigobe kanye nezinye izinhlobo zokubumba, ngaphandle kokulimaza ukugqoka.

5. Ngemva kokushiswa kwe-hot-dip galvanizing yezingxenye zensimbi, kulingana nokwelashwa okukodwa kwe-annealing, okungathuthukisa ngokuphumelelayo izakhiwo zemishini yesisekelo sensimbi, kuqede ukucindezeleka lapho kwakhiwa kanye nokushisela izingxenye zensimbi, futhi kusize ukuguqulwa kwamandla okucutshungulwa kwezingxenye zensimbi. .
