Dulmar guud ee xaashida birta galvanized ee darajada SGCC
Gariiradda birta galvanized ee kulul, xaashida birta ku salaysan gelisay zinc dhalaalaysa, ka dibna waxay noqon doontaa xaashida ku dheggan lakabka zinc. Waqtigan xaadirka ah inta badan waxay qabataa habka galvanizing joogto ah, kuwaas oo ku rid duubka joogtada ah ee gariiradda birta ee haanta dhalaalaysa ee zinc, ka dibna alloying birta galvanized. Noocaan saxan birta ah waxaa lagu sameeyaa habka kulul ee la rusheeyey, laakiin ka dib markii taangiga zn ka tago, isla markiiba kuleyl ilaa heerkul ah oo ku saabsan 500 ℃, waxay sameeyaan zinc iyo xuubka daawaha birta. Gariiradaha galvanized noocan ah waxay leeyihiin dahaar wanaagsan oo ku dheggan iyo alxanka.

Faahfaahinta Xirmada
Xirmooyinka Dhoofinta caadiga ah:
● Biraha galvanized birta ah ee birta ah ee darafyada gudaha iyo dibadda
● Biraha galvanized iyo saxanka ilaalinta derbiga warqadda biyuhu aanay biyuhu lahayn.
● Biraha galvanized iyo warqadaha biyuhu ka celinayaan agagaarka wareegga iyo ilaalinta boodhka.
● Ku saabsan baakadaha u qalma badda: xoojinta dheeraadka ah ka hor inta aan la rarin si loo hubiyo in alaabtu ay ka badbaado badan tahay oo aanay waxyeello u geysan macaamiisha.
