Waa maxay koronto-sameynta?
Electroplating waa habka loo isticmaalo mabda'a electrolysis si loo dhigo lakab khafiif ah oo biraha kale ah ama alwaaxyada sagxadaha birta qaarkood. Waa habka loo isticmaalo electrolysis si loogu dhejiyo filim bir ah oogada birta ama qaybaha kale ee walxaha, taas oo ka hortagaysa oksaydhka birta (sida miridhku), hagaajinta caabbinta xirashada, conductivity, milicsiga, caabbinta daxalka (sida copper sulfate), iyo hagaajinta bilicda.
Electroplating waxa kale oo loo sii qaybiyaa habab gaar ah sida dahaadhida naxaasta, dajinta dahabka, daarista qalinka, dheesha chromium, dajinta nikkel, iyo dajinta zinc. Warshadaha wax soo saarka, dhejinta zinc, dhejinta nikkel, iyo dajinta chromium ayaa si gaar ah loo isticmaalaa. Waa maxay farqiga u dhexeeya saddexdan?
01- Galvanization
Qeexid: Darista Zinc waxa loola jeedaa farsamada daawaynta oogada taas oo ku lug leh dahaadhka lakabka zinc ee korka birta, daawaha, ama walxo kale oo loogu talagalay ujeedooyinka qurxinta iyo ka hortagga miridhku.
Astaamaha: Qiimaha hooseeya, celceliska caabbinta daxalka, midab cad oo qalin ah.
Codsiga: Boolal, wareegyada wareegga, alaabta warshadaha, iwm.
02- Dajinta nikkelka
Qeexid: Habka lakabka nikkelka loogu dhejiyo birta ama biraha aan birta ahayn qaarkood iyada oo loo marayo korantada ama hababka kiimikada waxaa loo yaqaannaa nikkel plating.
Astaamaha: Quruxda, waxaa loo isticmaali karaa qurxinta, qiimaha sare, farshaxanimada yar ee adag, midabkuna waa lacag caddaan iyo jaalle ah.
Codsiga: Haysta laambada tamarta, qadaadiicda, qaybaha qalabka, iwm.
03- Ku darista Chromium
Qeexid: Chromium waa bir dhalaalaysa oo cad oo leh midab buluug ah. Habka loogu dhejiyo lakabka chromium birta ama qaar ka mid ah kuwa aan biraha ahayn iyada oo loo marayo electrolysis ama hababka kiimikada waxaa loo yaqaannaa chromium plating.
Astaamaha: Waxaa jira laba nooc oo chrome plating ah. Midka ugu horreeya waxaa loogu talagalay ujeedooyinka qurxinta, oo leh muuqaal dhalaalaya iyo caabbinta xirashada wanaagsan. Awooddeeda ka-hortagga miridhku uma fiicna sida tan dahaadhka zinc, laakiin way ka fiican tahay oksaydhka; Habka labaad waa in la kordhiyo adkaanta iyo xidhashada caabbinta qaybaha biraha, taas oo ah hawlaha qaybaha.
Codsiga: Qaybaha qurxinta dhalaalaya, qalabka, qasabadaha, iwm. ee qalabka guriga, elektiroonigga iyo alaabada kale.
Kordhi aqoonta:
1. Wax soo saarka korantada waxaa inta badan keena wasakhowga birta culus ee wasakhda wasakhda iyo bulaacada. Dalku waxa uu si adag u xakameeyay balaadhinta warshadaynta korantada oo sannadba sanadka ka dambaysa hoos u sii dhacayay.
Dalka Shiinaha, farsamaynta korantada inta badan waxa ay ku lug leedahay galvanization, plating copper, plating nickel, iyo chromium plating, iyada oo galvanization xisaabinteeda ay tahay 50%
Haddii ujeedadu tahay in laga hortago miridhku, galvanizing ama cadmium plating waa la isticmaali karaa; Haddii diiradda la saarayo ka hortagga xirashada, nikkel ama dajinta chromium ayaa ah doorashada ugu fiican.
