Galvanized steel channel soo saarid kulul giringiriyey
Hordhac
Kanaalka birta galvanized waa bir dheer oo leh qayb qaabaysan. Birta kanaalka galvanized kulul-muquufin kara waxaa loo qaybin karaa kulul-muquufin kara kanaalka birta iyo kanaalka galvanized kulul-afuufay iyadoo loo eegayo habka galvanizing kala duwan. Waa birta ka dib marka la tirtiro. Qaybaha waxaa lagu dhex shubaa zinc-ka dhalaalaysa ee ku dhawaad 440 ~ 460 ℃ si ay u sameeyaan dusha sare ee qaybaha birta ee ku dheggan lakabka zinc, sidaas darteed lagu gaaro ujeedada ka hortagga daxalka. Ka mid ah hababka daahan ee kala duwan ee ilaalinta substrates birta, galvanizing kulul-muquufin waa mid aad u wanaagsan. Waa marka zinc uu ku jiro xaalad dareere ah, ka dib ficilada jirka iyo kiimikaad ee adag ka dib, birta laguma dhejin karo oo kaliya lakab zinc ah oo dhumuc weyn, laakiin sidoo kale lakabka zinc-iron ayaa la sameeyay. Habka daadintu ma aha oo kaliya inuu leeyahay sifooyinka iska caabbinta daxalka ee electro-galvanization, laakiin sidoo kale wuxuu leeyahay lakabka daaha ee zinc-iron. Waxa kale oo ay leedahay iska caabin daxalka oo xooggan oo aan la barbar dhigi karin koronto-galvanizing. Sidaa darteed, habkan daadintu wuxuu si gaar ah ugu habboon yahay noocyo kala duwan oo aashito ah oo xooggan, ceeryaamo alkali ah iyo deegaanno kale oo xoog leh.
