galvalume/aluzinc gariiradda
gariiradda birta galvanized
Dahaarka dusha sare ee gariiradaha zinc ee aluminiumku wuxuu ka kooban yahay 55% aluminium, 43.5% zinc iyo qadar yar oo walxo kale ah.Dusha sare ee dahaadhka aluminium ee zinc waa qaab-dhismeedka malabka ee hoos yimaada aragtida yar-yar, iyo "xanabka malabka" ee ka samaysan aluminium ka kooban yahay zinc.Xaaladdan oo kale, inkasta oo daahan aluminium-zinc ah ayaa sidoo kale ka ciyaara doorka ilaalinta anode, dhinaca kale, sababtoo ah hoos u dhigista maadada zinc, dhinaca kale, walxaha zinc waxaa lagu duudduubay aluminium oo ma fududa in la koronto. markaa doorka ilaalinta anode-ka ayaa si weyn loo dhimay.Sidaa darteed, marka aluminium la dhejiyo Saxanka zinc waa la gooyaa, oo wuxuu daxaloobayaa dhawaan marka cidhifka la gooyey asal ahaan lumo oo la ilaaliyo.Sidaa darteed, saxanka aluminium-zinc waa in la gooyaa sida ugu yar ee suurtogalka ah.Marka la gooyo, cidhifka waxaa lagu ilaalin karaa iyadoo la marinayo rinjiga ka hortagga miridhku ama rinjiga zinc-hodanka ah.Nolosha adeega taarikada.
Dusha sare ee gariiradda birta galvalume/aluzinc/zincalum waxay soo bandhigaysaa ubax xiddigeed siman oo siman oo qurux badan, midabka salkuna waa qalin-cad.Qaab dhismeedka gaarka ah wuxuu ka dhigayaa iska caabin aad u fiican.Nolosha adeegga caadiga ah ee saxan aluminium-zinc waxay gaari kartaa 25a, waxayna leedahay iska caabin kulayl wanaagsan waxaana loo isticmaali karaa jawi heerkul sare ah 315 ° C;adhesion ee dahaarka iyo filimka rinji waa wanaagsan yahay, oo waxay leedahay sifooyin habayn wanaagsan, oo la feeray, la gooyaa, alxanka, iwm;conductivity dusha waa mid aad u wanaagsan.
Halabuurka daahan wuxuu ka kooban yahay 55% aluminium, 43.4% zinc, iyo 1.6% silikoon saamiga miisaanka.Habka wax soo saarka ee gariiradda birta galvalume waxay la mid tahay kan gariiradda birta galvanized iyo gariiradda aluminium, taas oo ah habka daahan dhalaalid joogto ah.Gariiradda galvalume/aluzinc oo leh 55% aluminium-zinc alloy daahan ayaa iska caabbinta daxalka ka fiican ka leh xaashida galvanized ee dhumucda isku midka ah marka ay soo baxdo isla jawiga labada dhinac.55% aluminium-zinc alloy dahaarka aluminium-zinc birta birta ah ma aha oo kaliya caabbinta daxalka wanaagsan, laakiin sidoo kale waxay leedahay ku dhejinta iyo dabacsanaanta alaabta midabka leh.
Farqiga u dhexeeya galvalume/aluzinc iyo gariiradaha galvanized ayaa inta badan ah farqiga u dhexeeya dahaarka.Dusha sare ee xaashida galvanized ayaa si siman loo qaybiyaa lakabka walxaha zinc, kaas oo u dhaqma sida ilaalinta anodic ee walxaha saldhigga ah, taas oo ah in la yiraahdo, ilaalinta daxalka kale ee walxaha zinc.Marka lagu daro isticmaalka alaabta saldhigga ah, walxaha saldhigga ah ee gudaha ku jira ayaa kaliya waxyeello u geysan kara marka zinc si buuxda u daxaloobaan.
