Galvanization-kululwaa geedi socod ah in walxo bir ah ama qayb leh oo nadiif ah lagu dhex geliyo dareeraha zinc la dhalaaliyay, iyo lakabka zinc birta ah ayaa ka sameysma dusha sare iyada oo loo marayo fal-celin jireed iyo kiimikaad at interface.Galvanizing-kulul, oo sidoo kale loo yaqaan galvanizing-kulul-kulul iyo galvanizing-kulul, waa hab wax ku ool ah oo birta ka-hortagga daxalka, kaas oo inta badan loo isticmaalo ka-hortagga dusha sare ee dhismayaasha birta, tas-hiilaadka iyo agabyada warshadaha kala duwan.Haddaba maxay yihiin astaamaha lagu gartogalvanized galvanized kulul tuubo bir ah oo aan kala go 'lahayn?

1. Xirmooyinka cawl ee cabbirrada kala duwan ee dusha sare ee birta birta ah ee galvanized waa kala duwanaanshaha midabka galvanizing, taas oo ah dhibaato adag oo ka jirta warshadaha galvanizing, inta badan waxay la xiriirtaa walxaha raadraaca ee ku jira tuubada birta lafteeda iyo qaybaha qubeyska zinc.Wasakhdu ma saameynayso waxqabadka ka-hortagga daxalka ee tuubada birta, kaliya farqiga muuqaalka.

2. Waxa si tartiib tartiib ah u muuqda calaamado kor u kacaya oogada sare ee tuubo kasta oo galvanized ah oo bilaa tol ah, kuwaas oo dhamaantood ah zinc, kaas oo lagu sameeyay qaboojinta iyo adkaynta dareeraha zinc ee ku qulqulaya derbiga tuubada ka dib markii tuubada birta ah ee galvanized laga soo saaro dheriga zinc.

4. Macaamiisha qaar ayaa isticmaali doona isku xirka jeexjeexa habka ay u isticmaalayaan birta galvanized-ka ah si ay u riixaan jeexdin.Sababo la xiriira lakabka zinc qaro weyn ee tuubada birta ah ee kulul ee galvanized galvanized bir ah oo aan kala go 'lahayn, hoos ficilka xoogga dibadda ee wax burburiya, qayb ka mid ah lakabka galvanized ayaa dillaaci doona oo dillaaci doona, taas oo aan wax shaqo ah ku lahayn tayada birta birta ah ee galvanized lafteeda. .

5. Macaamiisha qaar ayaa ka falcelin doona inuu jiro dareere jaale ah tuubada birta ah ee galvanized-ka ah (dareerehan waxa loo yaqaan dareeraha passivation), kaas oo dhaafi kara dusha birta.Guud ahaan waxaa loo isticmaalaa daawaynta post-plating ee galvanized, cadmium iyo daahan kale.Ujeeddadu waa in la sameeyo xaalad dusha sare ee dusha sare ee daahan kaas oo ka hortagi kara falcelinta caadiga ah ee birta, hagaajinta caabbinta daxalka, iyo kordhinta bilicda alaabta.Waxay si wax ku ool ah u wanaajin kartaa iska caabbinta daxalka ee tuubada birta waxayna sii dheereysaa nolosha adeegga shaqada.

Saamaynta ilaalinta lakabka galvanized kulul ee tuubada birta ah ee bilaa-xarafka ah ayaa aad uga fiican tan rinjiga ama lakabka caagga ah.Habka galvanizing-ku-kulul, zinc wuxuu ku kala firdhiyaa birta si uu u sameeyo lakab isku-dhafan oo isku-dhafan oo zinc-iron ah, taas oo ah, lakab daawaha ah.Lakabka daawaha waxa uu si bir ah ugu xidhan yahay birta iyo zinc, kaas oo ka xoog badan xidhiidhka ka dhexeeya rinjiga iyo birta.Lakabka galvanized-ku-kululku wuxuu u muuqdaa jawiga jawiga mana dhaco tobanaan sano ilaa uu si dabiici ah u daxaloobay.

Farsamada galvanizing-ku-kulul eetuubo bir ah oo aan lahaynguud ahaan waxa loo qaybin karaa dahaadhid dharbaaxo ah iyo dahaadhid afuufis ah:

1. Duubista.Ku qabooji biyo si toos ah ka dib markaad qoosho.Celceliska dhumucda lakabka zinc wuxuu ka weyn yahay 70 microns, markaa qiimaha galvanizing waa mid sarreeya, qadarka zinc waa weyn yahay.Deegaanka caadiga ah ee jawiga in ka badan 50 sano, waxaa jira raad cad oo qulqulka zinc, iyo tuubada birta ah ee ugu dheer ayaa lagu dhejin karaa 16m.

2. Duubista.Galvanizing ka dib, dibadda waa la afuufi oo gudaha waa la qaboojiyey.Celceliska dhumucda lakabka zinc wuxuu ka weyn yahay 30 microns, qiimuhu waa yar yahay, isticmaalka zinc waa yar yahay.Ka dib in ka badan 20 sano oo loo isticmaalo jawiga jawiga caadiga ah, ku dhawaad ​​wax raad ah oo dareeraha zinc ah lama arki karo.Xariiqda wax soo saarka zinc ee la afuufay guud 6-9m.
