Silsilad bir ah oo galvanized ah ayaa u fiican mashruucaaga
Silsiladda birta galvanized waa falcelinta birta dhalaalaysa iyo matrix birta si ay u soo saarto lakab alloy ah, si matrixka iyo dahaarka la isku daro.Silsiladda birta galvanized ayaa ah silsiladda ugu horreysa ee lagu qaado, si looga saaro oksaydhka birta ee dusha sare ee silsiladda, ka dib marka la qaado, iyada oo loo marayo ammonium chloride ama zinc chloride aqueous ama ammonium chloride iyo zinc chloride oo isku dhafan haanta dareeraha aqueous si loo nadiifiyo, ka dibna ku shubta haanta kulul ee kulul.Silsiladda birta ah ee galvanized waxay leedahay faa'iidooyinka dahaadhka isku midka ah, adhesion xooggan iyo nolol adeeg oo dheer.
Silsiladda birta ah ee galvanized-ka ah waxa lagu galvanized kulul maquufin ku salaysan silsilad bir welded (yacni, Zincku waxa uu ku milmay dheriga zinc ah, ka dibna silsiladda waxaa la rusheeyaa zinc dareere ah in muddo ah si ay u soo saaro, ka dibna qaboojin iyo qalajinta. ).
Darbiyada gudaha iyo dibadda ee silsiladdu waxay leeyihiin lakab zinc ah oo isku mar ku xiran.Silsiladaha birta galvanized ayaa guud ahaan loo isticmaalaa gudbinta dareeraha cadaadiska hooseeya (sida biyaha, gaaska dareeraha ah).
Tilmaamaha jireed ee silsiladaha caadiga ah iyo silsiladaha galvanized waa isku mid, laakiin sababtoo ah dahaarka dusha sare waa ka duwan yahay, iska caabbinta daxalka ma aha mid isku mid ah.
Mid ka mid ah, silsiladda caadiga ah: chromium waa bir midab qalin ah, aad bay u xasilloon tahay jawiga, xitaa alkali, nitric acid, sulfide, xal karboonku waxay sidoo kale ilaalin kartaa xaalad deggan.Chrome wuxuu leeyahay qaab-dhismeed adag, iska caabin xoog leh, wuxuuna hayn karaa dhalaalkiisa muddo dheer.Dhibta ay leedahay dahaadhida chromium waa in aanay ka ilaalinayn birta salka ka miridhku.Sidaa darteed waxaa ka horreeya dahaadh naxaas ah ama naxaas-tin alloy ah oo si fiican ugu xidha birta saldhigga ah.Guud ahaan, silsiladda chrome-plated waxay leedahay sifooyinka qiimaha wax yar ka sarreeya, baabuurta heerka sare ee gudaha, baabuurta la qaadi karo inta badan, guud ahaan laguma talinayo in la isticmaalo.
Laba, silsilad galvanized: muuqaalka silsiladda galvanized ee midabka cagaaran.Taasi waa natiijada ka dhalata dahaadhka zinc oo ay ku xigto bleaching.Dahaarka zinc wuxuu wax yar ku beddelaa hawada engegan.Hawada qoyan, biyaha ay ku jiraan kaarboon oksijiin iyo oksijiin, oogada sare waxay samaysaa filim khafiif ah oo ah zinc carbonate aasaasiga ah.Filimkani wuxuu leeyahay saamaynta ka hortagga daxalka.Waxay ka hortagi kartaa daxalka dheeraadka ah ee birta.Waxaan aragnaa in qaar ka mid ah silsiladaha galvanized ay si dhakhso ah uga beddelaan caddaan ilaa brown si degdeg ah isticmaalka ka dib, laakiin ma jiro isbeddel weyn oo tan ka dib, sababtu waa taas.
Marka la barbardhigo silsiladaha caadiga ah, silsiladaha galvanized ee wax soo saarka iyo farsamaynta ka dib daaweynta galvanized gaar ah, isticmaalka sifooyin aad u fiican, si haddii nolosha badeecada ama isticmaalka dhabta ah ee kor ku xusan ay leedahay heerar kala duwan oo hagaajin ah.Habka galvanized waa mid sahlan, qiimuhu waa mid hooseeya, sidaas darteed nooca caadiga ah, baaskiilka culus ayaa loo isticmaalaa.
