CS-B Galvanized Steel Rolled Steel Coil

Xaashiyaha galvanized waxaa loola jeedaa saxanka birta ah ee lagu dahaadhay lakabka zinc. Galvanizing waa hab dhaqaale iyo waxtar leh oo ka-hortagga rukhsadda kaas oo inta badan la isticmaalo. Qiyaastii kala badh wax soo saarka zinc ee adduunka ayaa loo isticmaalaa habkan.
Xaashiyaha birta galvanized waa in laga hortago daxalka dusha sare ee saxanka birta oo ay u dheereyso nolosha adeeggeeda. Lakabka zinc birta ah ayaa lagu dahaadhay dusha sare ee saxanka birta, kaas oo loo yaqaan saxanka galvanized.

Gariirada birta Galvanized waxay soo mareen hannaan kiimiko si ay uga ilaaliyaan daxalka. Birta waxa lagu dahaadhay lakabyo zinc ah sababtoo ah miridhku ma weerari doono birtan ilaalinta ah. Habka ugu muhiimsan ee samaynta birta iska caabbinta daxalka waa iyada oo lagu daro bir kale, Zinc. Marka birta lagu dhex milmo zinc dhalaalaysa, falcelinta kiimikaad waxay si joogto ah ugu xidhaa zinc-ga birta iyada oo loo marayo galvanizing. Sidaa darteed, zinc-ku maaha mid sax ah. , sida rinjiga, sababtoo ah kaliya ma daboosho birta; dhab ahaantii waxay noqotaa qayb ka mid ah.

Galvanization-ku-kulul waa nooc ka mid ah galvanization.It waa habka dahaadhidda birta iyo birta leh zinc, kaas oo alloys leh dusha birta saldhigga marka la geliyo birta qubeyska zinc la dhalaaliyay heerkul ah 840 ° F 449°C) Marka hawada la soo bandhigo, Zinc (Zn) saafi ah waxa ay la falgashaa ogsijiin(O2) si ay u samayso zinc oxide (ZnO), kaas oo sii la falgala kaarboon dioxide (CO2) si uu u sameeyo zinc carbonate (ZnCO3), sida caadiga ah cawl caajis ah, walxo cadaalad ah oo xoog leh oo ka ilaaliya birta ka hooseysa daxalka dheeraadka ah ee duruufaha badan Waxaa lagu aqoonsan karaa qaabaynta crystallization ee dusha sare (badanaa loo yaqaan "spangle").
