Inhloso yokuhlanganisa ama-cold galvanizing kanye nokuhlanganisa ama-hot galvaningizinti zezibani zelangaukuvimbela ukugqwala nokwandisa isikhathi sokusebenza kwezibani zasemgwaqweni zelanga, ngakho-ke uyini umehluko phakathi kwalezi ezimbili?
1. Ukubukeka
Ukubonakala kwe-galvanizing ebandayo kubushelelezi futhi kuyakhanya. Ingqimba ye-electroplating enenqubo yokudlulisa umbala iphuzi kakhulu futhi iluhlaza okotshani, inemibala eyisikhombisa. Ingqimba ye-electroplating enenqubo yokudlulisa emhlophe imhlophe okwesibhakabhaka, futhi inombala omncane ekhoneni elithile lokukhanya kwelanga. Kulula ukukhiqiza "ukushiswa kukagesi" emakhoneni nasemaphethelweni enduku eyinkimbinkimbi, okwenza ungqimba lwe-zinc kule ngxenye lube lukhuni. Kulula ukwakha ugesi ekhoneni langaphakathi futhi kukhiqize indawo engwevu engaphansi komswakama, okwenza ungqimba lwe-zinc kule ndawo lube luncane. Induku kufanele ingabi namaqhubu e-zinc kanye nokuhlangana.
Ukubonakala kwe-hot galvanizing kulukhuni kancane kunokwe-cold galvanizing, futhi kumhlophe njengesiliva. Ukubukeka kulula ukukhiqiza amamaki amanzi enqubo kanye namaconsi ambalwa, ikakhulukazi ekugcineni kwenduku.
Ungqimba lwezinki lwe-galvanizing eshisayo ebukhali kancane lukhulu ngokuphindwe kaningi kune-galvanizing ebandayo, futhi ukumelana kwayo nokugqwala nakho kuphindwe kaningi kune-galvanizing kagesi, futhi intengo yayo iphakeme kakhulu ngokwemvelo kune-galvanizing ebandayo. Kodwa-ke, ngokuhamba kwesikhathi, i-galvanizing eshisayo ngokuvimbela ukugqwala iminyaka engaphezu kweyi-10 izothandwa kakhulu kune-galvanizing ebandayo ngokuvimbela ukugqwala iminyaka eyi-1-2 kuphela.
2. Inqubo
I-cold galvanizing, eyaziwa nangokuthi i-galvanization, iwukusebenzisa imishini ye-electrolytic ukufaka induku esixazululweni esiqukethe usawoti we-zinc ngemva kokususa amafutha nokuwaxuba, bese uxhuma i-negative pole yemishini ye-electrolytic. Beka ipuleti le-zinc ohlangothini oluphambene lwenduku ukuze uyixhume esixazululweni esihle semishini ye-electrolytic, uxhume ugesi, bese usebenzisa ukunyakaza kokuqondisa kombane kusuka esixazululweni esihle kuya esixazululweni esibi ukuze ufake ungqimba lwe-zinc esiqeshini somsebenzi; I-hot galvanizing iwukususa uwoyela, ukuwasha nge-asidi, ukucwilisa umuthi bese womisa i-workpiece, bese uyicwilisa esixazululweni se-zinc esincibilikisiwe isikhathi esithile, bese uyikhipha.
3. Isakhiwo sokumboza
Kukhona ungqimba lwenhlanganisela ebuthakathaka phakathi kwengubo kanye nesisekelo se-hot galvanizing, kodwa lokhu akunawo umthelela omkhulu ekumelaneni kwayo nokugqwala, ngoba ingubo yayo iyingubo ye-zinc emsulwa, futhi ingubo iyafana, ayinazo izimbobo, futhi akulula ukuyigqwala; Kodwa-ke, ingubo ye-cold galvanizing yakhiwe ngama-athomu athile e-zinc, okuyingxenye yokunamathela ngokomzimba. Kunezimbobo eziningi ebusweni, futhi kulula ukuthintwa yindawo ezungezile futhi igqwale.
4. Umehluko phakathi kwalokhu okubili
Kusukela emagameni alawa amabili, kufanele sazi umehluko. I-zinc emapayipini ensimbi abandayo aqandisiwe itholakala ekushiseni kwegumbi, kanti i-zinc ekushiseni okuqandisiwe itholakala ku-450 ℃ ~ 480 ℃.
5. Ubukhulu bokumboza
Ubukhulu bokumbozwa kwe-cold galvanizing ngokuvamile buyi-3 ~ 5 μ m kuphela. Kulula kakhulu ukukucubungula, kodwa ukumelana kwayo nokugqwala akukuhle kakhulu; Ukwakheka kwe-hot-dip galvaning ngokuvamile kune-10 μ Ukumelana nokugqwala kobukhulu be-m nangaphezulu kungcono kakhulu, okuphindwe kaningi kunokwesigxobo sesibani se-cold-galvaning.
6. Umehluko wentengo
Ukushisa nge-galvanizing kuyinkinga kakhulu futhi kudinga kakhulu ekukhiqizeni, ngakho-ke amanye amabhizinisi anemishini emidala kanye nezinga elincane ngokuvamile asebenzisa imodi yokushisa nge-galvanizing ebandayo ekukhiqizeni, okuyinto ephansi kakhulu ngentengo nangezindleko; Kodwa-ke,abakhiqizi be-hot-dip galvanizingngokuvamile zisemthethweni kakhulu futhi zinkulu ngosayizi. Zilawula kangcono ikhwalithi kanye nezindleko eziphakeme.
Umehluko ongenhla phakathi kokushisa okushisayo nokubandayo kwezigxobo zezibani zasemgwaqweni zelanga kuhlanganyelwe lapha. Uma izigxobo zezibani zasemgwaqweni zelanga zizosetshenziswa ezindaweni ezisogwini, kumele zicabangele ukumelana nomoya kanye nokumelana nokugqwala, futhi zingadali iphrojekthi yokulahla udoti ngenxa yobugovu besikhashana.
