Umehluko phakathi kwe-electro-galvanizing kanye ne-hot-dip galvanizing

Ingaphezulu lensimbi ngokuvamile linesendlalelo esine-galvanized, esingavimbela insimbi ukuthi ingagqwali ngezinga elithile.Isendlalelo sensimbi esinothayela ngokuvamile sakhiwa ngokufaka uthayela oshisayo noma nge-electro-galvanizing.Ngakho yini umehluko phakathii-hot-dip galvanizingkanye ne-electro-galvanizing?

Electro Galvanizing Process

I-Electrogalvanizing, eyaziwa nangokuthi i-galvanizing ebandayo embonini, inqubo yokusebenzisa i-electrolysis ukwakha iyunifomu, insimbi ecinene futhi eboshwe kahle noma isendlalelo se-alloy deposition ebusweni bomsebenzi.

Uma kuqhathaniswa nezinye izinsimbi, i-zinc iyinsimbi eshibhile futhi ecwecwe kalula.Kuyi-coat elwa nokugqwala enenani eliphansi futhi isetshenziswa kabanzi ukuvikela izingxenye zensimbi, ikakhulukazi ekugqwaleni komkhathi, kanye nokuhlobisa.Amasu okucwenga ahlanganisa i-tank plating (noma i-rack plating), i-barrel plating (izingxenye ezincane), i-blue plating, i-othomathikhi yokucwenga kanye ne-continuous plating (for wire, strip).

Izici ze-electro-galvanized

Inhloso ye-electrogalvanizing ukuvimbela izinto zensimbi ukuthi zingagqwali, ukuthuthukisa ukumelana nokugqwala kanye nempilo yesevisi yensimbi, futhi ngesikhathi esifanayo ukwandisa ukubukeka kokuhlobisa komkhiqizo.Insimbi izoba yisimo sezulu, amanzi noma umhlabathi ugle ngokuhamba kwesikhathi.Insimbi egqwala minyaka yonke e-China yenza cishe ingxenye eyodwa kweshumi yenani lensimbi.Ngakho-ke, ukuze kuvikelwe impilo yesevisi yensimbi noma izingxenye zayo, i-electro-galvanizing ngokuvamile isetshenziselwa ukucubungula insimbi.

Njengoba i-zinc akulula ukuyishintsha emoyeni owomile, futhi ingakhiqiza ifilimu eyisisekelo ye-zinc carbonate endaweni enomswakama, le filimu ingavikela izingxenye zangaphakathi emonakalweni wokugqwala, noma ngabe ungqimba lwe-zinc lonakaliswa yisici esithile.Kwezinye izimo, i-zinc nensimbi kuhlangana ngokuhamba kwesikhathi ukwakha ibhethri elincane, ne-matrix yensimbi evikelwe njenge-cathode.Isifinyezo se-Electrogalvanizing sinezici ezilandelayo:

1. Ukumelana nokugqwala okuhle, inhlanganisela ecophelelayo neyunifomu, akulula ukungena ngegesi egqwalayo noma uketshezi.

2. Ngenxa yokuthi ungqimba lwezinc lumsulwa, akulula ukugqwala endaweni ene-asidi noma ye-alkali.Vikela ngokuphumelelayo umzimba wensimbi isikhathi eside.

3. Ngemuva kokudlula nge-chromic acid, ingasetshenziswa ngemibala ehlukahlukene, engakhethwa ngokuvumelana nezintandokazi zamakhasimende.I-galvanizing inhle futhi ihlobisa.

4. I-zinc coating ine-ductility enhle futhi ngeke iwe kalula ngesikhathi sokugoba okuhlukahlukene, ukuphatha kanye nomthelela.

Uyini umehluko phakathi kwe-hot-dip galvanizing kanye ne-electro-galvanizing

Izimiso zalokhu kokubili zihlukene.I-Electrogalvanizing iwukunamathisela ungqimba olunathayela phezu kwensimbi ngendlela ye-electrochemical.I-hot-dip galvanizingukucwilisa insimbi kwisisombululo se-zinc ukwenza ingaphezulu lensimbi ngongqimba olunama-galvanized.

Kunomehluko ekubukekeni phakathi kwalokhu okubili.Uma insimbi i-electro-galvanized, ubuso bayo bushelelezi.Uma insimbi ifakwe i-hot-dip galvanized, ingaphezulu layo lilukhuni.Ama-electro-galvanized coatings ngokuvamile angu-5 kuya ku-30μm, kanye nezigqoko ezishisayo zediphu ngokuvamile zingu-30 kuya ku-60μm.

Ububanzi bokusebenza buhlukile, i-hot-dip galvanizing isetshenziswa kakhulu kunsimbi yangaphandle efana nothango lomgwaqo onguthelawayeka, futhi i-electro-galvanizing isetshenziswa kakhulu kunsimbi yasendlini njengamaphaneli.
