Habka lagu kala soocayo electrogalvanizing iyo galvanizing kulul

Xidhiidhiyayaasha waxay ka tirsan yihiin qaybaha guud ee aasaasiga ah, oo badanaa sidoo kale loo yaqaan "qaybaha caadiga ah".Qaar ka mid ah xirmooyinka leh xoogga sare iyo saxda ah, daaweynta dusha ayaa xitaa ka muhiimsan daaweynta kulaylka.Dhammaan noocyada xirmooyinka loo isticmaalo in tiro badan oo ah qalabka farsamada, ku dhawaad ​​oo dhan u baahan yihiin in la soo ururiyey ka dib markii daaweynta dusha, si loo gaaro anticorrosion, decoration, xidho iska caabin ah, la yareeyo coefficient khilaaf iyo saamaynta kale, iyo daawaynta dusha aanorganic electrogalvanizing iyo galvanizing kulul waa tignoolajiyada dahaarka ilaalinta cathodic.

Mabda'a of electrogalvanizing alaabta xidhe birta waa isticmaalka electrolysis, formation of lebis, cufan, biraha si fiican isku dhafan ama daaha dhigaalka daaha on dusha workpiece ah, formation of lakabka ah ee daahan on dusha birta ah, si ay u gaadhaan ilaalinta habka daxalka birta.Sidaa darteed, daahan electrogalvanized waa dhaqdhaqaaq jihada ka electrode togan ilaa electrode taban iyadoo la isticmaalayo hadda.Zn2+ ee elektrolytka ayaa nukleed, koray oo lagu shubaa substrate-ka hoos yimaada ficilka suurtagalka ah si loo sameeyo lakab galvanized ah.Geedi socodkan, ma jiro habka fidinta ee u dhexeeya zinc iyo birta.Laga soo bilaabo fiirsashada microscopic, waa inay noqotaa lakab zinc saafi ah.Nuxur ahaan, diirka kulul ee galvanized birta-zinc alloy lakabka iyo lakabka zinc saafi ah, iyo galvanized oo kaliya lakabka lakabka zinc saafi ah, sidaas darteed, oo leh lakabka daaha birta-zinc ee daahan ayaa inta badan ku salaysan aqoonsiga habka daahan, ku haboon xirmooyinka galvanized, silig birta, dhuunta birta iyo alaabada kale.Habka Metallographic iyo habka XRD ayaa loo isticmaalaa in lagu ogaado daahan si loo kala saaro electrogalvanizing iyo galvanizing kulul, iyo in la siiyo hagitaan falanqaynta guuldarada.

Waxaa jira laba hab oo lagu garto dahaarka galvanizing kulul.Mid waa habka metallografiga: habka metallografigu kuma koobna baaxadda nuxurka iyo cabbirka muunadda, wuxuuna ku habboon yahay dhammaan alaabada galvanizing elektrogalvanizing iyo kulul.Midda kale waa habka kala qaybinta raajada: lagu dabaqi karo dhexroorka in ka badan 5mm boolal dahaadh ah iyo lowska diyaaradda lix geesoodka ah;Dhexroorka dibadda waa ka weyn yahay 8mm biraha dusha alaabta shucaaca, si loo hubiyo in muunad la samayn karaa galay size ugu yar ee 5mm × 5mm muunad guri, iyo dhammaan noocyada alaabta daahan.Xaqiijin kara qaabdhismeedka crystal ee content daahan ≥5% wajiga.Muunado leh kayd zinc saafi ah oo aad u qaro weyn kuma habboona kala-duwanaanta raajada.
