Alaabta noocan oo kale ah ayaa sidoo kale lagu sameeyaa iyadoo la isticmaalayo habka kululaynta, laakiin ka dib marka ay ka baxdo taangiga, isla markiiba waxaa lagu kululayn doonaa ilaa 500 ℃ si loo sameeyo filim khafiif ah oo zinc iyo bir ah.Xaashidan galvanized waxay leedahay cidhiidhi daahan wanaagsan iyo alxanka.

Khadka wax-soo-saarka galvanized iyadoo la adeegsanayo habka wax-soo-saarka birta ee ugu horumarsan ee Maraykanka, qeexitaannada ugu muhiimsan ee badeecadu waa 0.15-1.5mm * 800 ~ 1250mm.Khadka wax soo saarka ayaa lagu qalabeeyaa shucaaca foornada foornada joogtada ah;tuubada kuleylka nooca jet-ka toosan ee soo noqnoqoshada induction kuleylinta dheriga zinc dhoobada;afar mindi hawada dalool;mashiinka iftiinka;Mashiinka toosinta iyo qalabka kale ee horumarsan, Waxaan ku bilownay tignoolajiyada patented: Qalabka isticmaalka kulaylka qashinka, kaas oo badbaadin doona tamar badan iyo ilaalinta deegaanka.

Lakabka daawaha ee zinc iyo birta waxaa lagu sameeyay daahan oo dhan iyadoo lagu daweynayo kulaylka birta ee ka gudubta dareeraha qubeyska galvanizing.Dahaarka ayaa u muuqda cawl madow oo aan lahayn dhalaal macdan ah.Way fududahay in budo lagu sameeyo inta lagu jiro habka qaabaynta rabshadaha.Waa lagu dabaqi karaa dahaarka laga yaabo in la rinjiyeeyo iyada oo aan daaweyn dheeraad ah la helin marka laga reebo nadiifinta guud.

Xaashiyaha galvanized ee daawaha leh

Darajada birta daawaha qaab dhismeedka waxa matala nambarada Carabiga iyo calaamadaha curiyaha kiimikaad ee caadiga ah.Laba nambar oo Carabi ah ayaa loo isticmaalaa si ay u matalaan celceliska nuxurka kaarboonka (x/10000) iyo meelaynta madaxa fasalka.The
Nuxurka walxuhu waxa uu u taagan yahay sida soo socota: Marka celceliska nuxurku ka yar yahay 1.50%, lambarka darajo ayaa kaliya tilmaamaya curiyaha guud ahaanna ma tilmaamayo waxa ku jira;Marka celceliska nuxurkiisu yahay 1.50%~2.49%, 2.50%~3.49%, 3.50%~4.49%, 4.50%~5.49%, 2, 3, 4 iyo 5 waxaa la qoraa iyadoo la raacayo curiyeyaasha alloying.Tusaale ahaan: Celceliska waxa ku jira kaarboon, chromium, manganese iyo silicon ee birta daawaha dhismaha waa 0.30%, 0.95%, 0.85% iyo 1.05%.Marka waxa ku jira S iyo P ay yihiin ≤0.035%, darajadu waxay tilmaamaysaa "30CrMnSi".Biraha qaab dhismeedka tayada sare leh (S iyo P content ≤0.025%) ayaa lagu muujiyay in lagu daro "A" darajada.Tusaale ahaan: "30CrMnSiA".Biraha qaab dhismeedka tayada sare ee heerka sare ah (S≤0.015%, P≤0.025%) waxa lagu tilmaamay in lagu daro "E" darajada.Tusaale ahaan: "30CrM nSiE".Darajada birta daawaha qaab dhismeedka gaarka ah waa in ay ku daraa calaamad muujinaysa ujeedada alaabta ee Jadwalka 1 madaxa darajada (ama dabada).Tusaale ahaan, darajada 30CrMnSi birta ee birta riveting waxaa lagu tilmaamay ML30CrMnSi.2. Habka matalayo ee darajada birta daawaha ee daawaynta waxay la mid tahay birta daawaha qaab dhismeedka.Tusaale ahaan: Celcelis ahaan waxa ku jira kaarboon, Silicon iyo manganese waa 0.60%, 1.75% iyo 0.75% birta guga, darajadana waxa lagu matalay “60Si2Mn”.Birta guga ee tayada sare leh, sumadda "A" ayaa lagu daraa darajada, darajadana waxaa lagu matalay "60Si2MnA".
