What is the difference between hot dip galvanizing and electric galvanizing

Ingaphezulu lensimbi livame ukumbozwa nge-zinc, elingavimbela insimbi ukuthi ingagqwali ngezinga elithile. Ungqimba olunamanzi ensimbi ngokuvamile lwakhiwa ngokufaka uphethiloli wediphu eshisayo noma ngokufaka ugesi kagesi, khona-ke yini umehluko phakathiidiphu elishisayo livuthela amanzifuthiugesi kagesi?

Okokuqala : uyini umehluko phakathi kwe-hot dip galvanizing kanye ne-electric galvanizing

Lezi zimiso ezimbili zihlukile.I-galvanizing kagesiixhunywe ebusweni bensimbi ngendlela ye-electrochemical, futhi ukugalela okushisayo kunamathiselwe ebusweni bensimbi ngokucwilisa insimbi oketshezini lwe-zinc.

Kukhona umehluko ekubukeni kokubili, uma insimbi isetshenziswa ngendlela yokufaka ugesi kagesi, ubuso bayo bubushelelezi. Uma insimbi iyindlela yokufaka idiphu eshisayo, ingaphezulu layo lilukhuni. Ukumbozwa kwe-galvanizing kagesi kuvame u-5 kuya ku-30μm, futhi ukumbozwa kokufaka ama-galvanizing ashisayo ngokuvamile ku-30 kuya ku-60μm.

Ububanzi bokufaka isicelo buhlukile, i-hot dip galvanizing isetshenziswa ensimbi yangaphandle efana nothango lomgwaqo onguthelawayeka, futhi ukufakwa kukagesi kusetshenziselwa insimbi yasendlini njengamaphaneli.

Okwesibili : indlela yokuvimbelaukugqwala kwensimbi

1. Ngaphezu kokwelashwa kokuvimbela ukugqwala kwensimbi nge-electroplating ne-hot plating, futhi sixubha uwoyela wokuvimbela ukugqwala phezu kwensimbi ukuze sizuze umphumela omuhle wokuvimbela ukugqwala. Ngaphambi kokuxubha uwoyela we-anti-rust, sidinga ukuhlanza ukugqwala endaweni yensimbi, bese sifafaza ngokulinganayo uwoyela ovimbela ukugqwala endaweni yensimbi. Ngemuva kokuthi amafutha angagqwali emboziwe, kungcono ukusebenzisa iphepha elingagqwali noma ifilimu yepulasitiki ukugoqa insimbi.

I-2, sifuna ukugwema ukugqwala kwensimbi, sidinga futhi ukunaka indawo yokugcina insimbi, isibonelo, ungafaki insimbi isikhathi eside endaweni emanzi futhi emnyama, ungafaki ngokuqondile insimbi phansi, ukuze ungangeni umswakama wensimbi. Ungagcini izimpahla ezine-asidi namagesi amakhemikhali endaweni lapho kugcinwa khona insimbi. Uma kungenjalo, kulula ukugqwala umkhiqizo.
