Gariiradda Birta Galvalumed Daabacaadda Far-diidka
Sharaxaada badeecada
Gariiradda birta galvalumed waa aluminium zinc aluminium qaab-dhismeedka aluminium 55%, zinc iyo 43.4% ka 1.6% Silicon at 600 ℃ adkeynta 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 wanaagsan oo badan: 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 caabbinta daxalka ee "gariiradda birta Galvalumed" waxaa inta badan sabab u ah shaqada ilaalinta aluminium.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.
★ U adkaysiga 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 milicsada:Birta galvalumed, oo inta badan loo isticmaalo walxo dahaadhid ahaan, waxay leedahay milicsiga kulaylka sareeyo, laba jeer ka badan birta galvanized.
Maadaama cufnaanta 55% al-zn uu ka yar yahay kan Zn, aagga aluminiumka iyo birta dahaadhka ah ee zinc waxay ka badan tahay 3% ka weyn birta dahaadhka ah ee isku miisaan iyo dhumucda isku mid ah.Qiimaha birta ee GL wuu ka fiican yahay GI.
