Macluumaadka Alaabta:
Silig galvanized TS EN 10244 Dahaarka birta ah ee zinc ee lagu dabaqo habka galvanizing waa hab wax ku ool ah oo lagula dagaallamo daxalka birta.Siliga galvanized ee ujeedooyinka guud ee wax soo saarka ayaa lagu heli karaa daahan galvanized caadiga ah ama daahan galvanized culus.
Dahaarka caadiga ah ee galvanized ayaa ka fudud, si kastaba ha ahaatee daxalka ka adkeysi yar yihiin dahaarka galvanized culus oo inta badan waxaa loo isticmaalaa silig caadiga ah codsiyada shaqada.Qaar ka mid ah isticmaalayaasha dhamaadka caadiga ah waxaa ka mid ah qafisyada, gacan-qabashada baaldiga, jaakadaha dharka lagu xidho iyo dambiisha.
Dahaarrada galvanized culus ayaa loo isticmaalaa xaaladaha ay daxalka atmospheric uu daran yahay.Isticmaalayaasha ugu dambeeya waxaa ka mid ah fiilooyinka taageerada dalagga halkaasoo kiimikooyinka lagu isticmaalo, deyrka barkada ama mesh silsiladda meelaha xeebaha ah.

Tilmaamaha Shaqeynta Siliga Galvanized
Marka la eego in siligga galvanized loo kala saaray iyadoo loo eegayo xaddiga daahan zinc, shaxda soo socotaa waxay qeexaysaa faraqa u dhexeeya heerka caadiga ah, galvanized culus iyo silig galvanized-sare oo dheeraad ah.

Xakamaynta tayada
Waxaan isticmaalnaa guud ahaan nidaamka xakamaynta tayada.Qayb kasta oo alaabta ceeriin ah;Alaabta dhammaatay iyo alaabta dhammaatay waa la tijaabiyay oo lagu duubay faylka.Rikoorka raadraaca waxa loo isticmaalaa laga soo bilaabo alaabtii u dambaysay ilaa bilawgii ugu horeeyay ee warshada birta alaabta ceeriin.
Qaybta saddexaad sida SGS ayaa diyaar u ah xakamaynta tijaabada ka hor inta aan la rarin.
Baakad:
1) Dhammaan alaabooyinka waxaa ka buuxa baakad badeed mudan.
2) Shuruudaha gaarka ah ee macaamilka ee xirxirida waa la buuxin karaa.
3) Xamuulka hawada;Xamuulka badda iyo xamuulka waa la heli karaa.
Habka sawirka:
Dajinta ka hor habka sawirka: Si loo hagaajiyo waxqabadkasilig bir galvanized, Habka ay siligga birta u sakhiray gubashada rasaasta, galvanizing ka dibna sawiridda alaabta la dhammeeyey waxaa loo yaqaannaa habka ugu horreeya ee dhejinta ka dibna sawirka.Socodka caadiga ah waa: silig bir ah - deminta rasaasta - galvanizing - sawir - silig bir ah oo dhammaatay.Habka ugu horreeya ee galvanizing ka dibna sawirku waa habka ugu gaaban habka sawirka ee silig birta galvanized, kaas oo loo isticmaali karo sawirida ka dib galvanizing kulul ama electro-galvanizing.Sawirka galvanizing kulul ka dib wuxuu leeyahay sifooyin farsamo oo ka wanaagsan sawirida iyo fiilada birta ah marka hore, iyo sawirida ka dib electro-galvanizing waxay ka dhigaysaa lakabka zinc mid cufan oo adkaysi leh.Labaduba waxay heli karaan lakab zinc ah oo khafiif ah oo labis ah, waxay yareeyaan isticmaalka zinc waxayna yareeyaan culeyska khadka galvanizing.
Habka sawirida ka dib dajinta dhexe: habka sawirida ka dib dajinta dhexe waa: silig birta - deminta rasaasta - sawirka aasaasiga ah - galvanizing - sawir sare - silig bir dhammeeyey.Astaamaha dahaadhka dhexe iyo sawir-qaadista ka dib ayaa ah in siligga birta ah ee sunta rasaasta ah la sawiro hal mar, ka dibna galvanized, ka dibna laba jeer la sawiro alaabta la dhammeeyey.Lakabka Zinc ee siligga birta ah ee lagu soo saaro dajinta dhexda ka dibna jiidaya ayaa ka dhumuc weyn marka hore dahaadhidda ka dibna jiidaya.Galvanization-ku-kululku wuxuu siin karaa cadaadis guud oo sarreeya (laga bilaabo daminta rasaasta ilaa alaabta dhammaatay), taas oo ka fiican galvanizing ka dibna sawir.
Habka Jiididda iyo Dajinta Isku Dhafan: Si loo soo saaro xoog aad u sarreeya (3000 N/mm2) silig bir galvanized ah, habka "daadin isku qasan iyo jiidid" ayaa la isticmaalaa.Habka socodka caadiga ah waa sida soo socota: deminta rasaasta - hal sawir - pre-galvanizing - sawir labaad - galvanizing final - saddex sawir (sawir qalalan) - haanta biyaha oo sawiraysa silig bir ah oo dhammaatay.Habka kor ku xusan wuxuu soo saari karaa silig bir ah oo aad u sarreeya oo leh kaarboon ah 0.93-0.97%, dhexroorka 0.26 mm, iyo xoogga 3921 N/mm2.Inta lagu jiro sawirka, lakabka zinc wuxuu ilaaliyaa oo saliideeyaa dusha sare ee siliga birta, mana jiro dillaac siliggu dhaco inta lagu jiro sawirka.
