Ubakaki owenziwe ngokwezifiso wokugoba wezingxenye zokunyathela zekheshi

Inqubo yokwenza i-galvanizing iwubuchwepheshe bokwelapha obungaphezulu obumboza ingaphezulu lezinto zensimbi eziyingxubevange ngongqimba lwezinc ukuze kulungiswe ubuhle nokuvimbela ukugqwala. Lokhu kunamathela kuyingqimba yokuvikela ye-electrochemical evimbela ukugqwala kwensimbi. Inqubo yokufaka uthayela isebenzisa izindlela ezimbili: i-hot-dip galvanizing kanye ne-electro-galvanizing.

I-hot-dip galvanizing ukufaka ucezu lokusebenzela kubhavu oshisayo ocwilisa amanzi bese ulufudumeza ufike ezingeni lokushisa elithile (imvamisa engu-440 kuya ku-480 ° C), ukuze ungqimba lwezinc luboshwe ngokuqinile ebusweni bomsebenzi ekushiseni okuphezulu yakha ungqimba olushisayo lwe-galvanizing. Khona-ke, ungqimba olunamanzi olushisayo luqiniswa ngokugcwele ngemva kokupholisa. I-hot-dip galvanizing inezinzuzo zekhwalithi ephezulu, isivuno esiphezulu, ukusetshenziswa okuphansi, izinzuzo ezibalulekile zezomnotho, njll., futhi inomphumela wokuvikela ku-anode. Lapho ukugqoka kuqedile, kungadlala indima yokuvikela; uma i-coating ingonakalisiwe kakhulu, i-coating ngokwayo izoguguleka ngenxa yesenzo se-electrochemical, ngaleyo ndlela ivikele insimbi ekugqwaleni.

I-Electro-zinc Plating ibeka ungqimba lwezinc phezu kwendawo yokusebenza ngokusebenzisa i-electrolysis. Le ndlela ifaneleka emigqonyeni emincane, futhi ukugqoka kufana kakhulu.

Amashidi akhandisiwe asetshenziswa kakhulu ekwakheni, ezintweni zikagesi zasendlini, ifenisha, ezokuthutha, insimbi nezinye izidingo zansuku zonke. Isibonelo, embonini yezokwakha, amashidi ama-galvanized asetshenziswa ophahleni, ama-balcony panel, ama-sills amafasitela, ama-warehouses, imigwaqo yomgwaqo omkhulu, njll.; embonini yemishini yasendlini, amashidi anathayela asetshenziswa eziqandisini, emishinini yokuwasha, amakhabethe okushintsha, ama-air conditioner, njll.; embonini yezokuthutha , uphahla lwezimoto, amagobolondo emoto, amaphaneli ekhompathimenti, iziqukathi, njll. nazo zizosebenzisa inqubo yokufaka uthayela.

Kodwa-ke, inqubo yokufaka ama-galvanizing nayo inezinkinga ezithile. Isibonelo, i-galvanized coating ingonakaliswa ukuguga kwemishini, ukugqwala, noma ezinye izici, ukunciphisa ikhono layo lokuvikela ngokumelene nokugqwala. Ezindaweni ezinezinga lokushisa eliphezulu, okokunamathisi kungase kuhluleke ngoba i-zinc inephuzu eliphansi lokuncibilika futhi ingancibilika kalula, iguquguquke, noma ilahlekelwe umphumela wayo wokuvikela emazingeni okushisa aphezulu. Ukwengeza, ukukhiqizwa nokucutshungulwa kwezingubo ezinamathayili kudla inani elikhulu lamandla namanzi, ngaleyo ndlela kubangele imithelela ethile yemvelo. Phakathi nenqubo yokukhiqiza nokucubungula, amanye amagesi ayingozi namanzi angcolile angase akhiqizwe, okungase kuthinte impilo yomuntu.

Ngokuvamile, inqubo yokwenza i-galvanizing iyindlela ebalulekile yensimbi yokulwa nokugqwala enezinhlobonhlobo zezicelo. Kodwa-ke, ekusetshenzisweni okungokoqobo, kuyadingeka futhi ukucabangela ukushiyeka okungenzeka futhi uthathe izinyathelo ezihambisanayo zokunciphisa umthelela wayo emvelweni nempilo yabantu.
