Gariiradda Birta Galvalumed Daabacaadda Farta-ka-hortagga
Sharaxaada badeecada
Gariiradda birta galvalumed waa aluminium aluminium qaab dhismeedka aluminium zinc 55%, zinc iyo 43.4% ka 1.6% Silicon at 600 ℃ adke heerkulka sare iyo ka kooban, ay qaab-dhismeedka oo dhan by aluminium - birta - Silicon - zinc, samaynta daawaha cufan ee crystal.
Tilmaamaha alaabta
★Tafatiraha sifooyinka:birta Galvalumed waxay leedahay sifooyin aad u fiican: iska caabin daxalka xooggan, saddex jeer oo ah dahaarka zinc saafiga ah;Iyada oo ubaxyo zinc ah oo qurux badan oo dusha sare ah, waxaa loo isticmaali karaa sidii loox dibadda ah ee dhismayaasha.
★ iska caabbinta daxalka:Iska caabinta daxalka ee "gariiradda birta ah ee Galvalumed" waxaa badanaa sabab u ah shaqada ilaalinta aluminiumka.Marka zinc la xidho, aluminiumku wuxuu sameeyaa lakab cufan oo aluminium ah, taas oo ka hortagaysa daxal kale oo ah walxaha u adkaysta daxalka ee gudaha.
★ Iska caabbinta kulaylka:Birta galvalumed waxay leedahay iska caabin kulayl oo wanaagsan waxayna u adkeysan kartaa heerkulka ka badan 300 darajo Celsius
Shiilooyinka, foornooyinka, nalalka, iyo nalalka cadceedda.
★ kulaylka milicsiga:Birta galvalumed, oo inta badan loo isticmaalo sida shay dahaarka ah, waxay leedahay milicsiga kulaylka sare, laba jeer ka birta galvanized.
Maadaama cufnaanta 55% al-zn uu ka yar yahay kan Zn, aagga aluminium iyo birta dahaadhka ah ee zinc waxay ka badan tahay 3% birta dahaadhka ah ee isku miisaan iyo dhumucda isku mid ah.Qiimaha birta ee GL wuu ka fiican yahay GI.
