Inhloso yokufaka ugqozi okubandayo kanye nokufaka ugqozi okushisayo kweizigxobo zezibani zelangaukuvimbela ukugqwala nokwandisa impilo yesevisi yezibani zasemgwaqweni zelanga, ngakho-ke uyini umehluko phakathi kokubili?
1. Ukubukeka
Ukubonakala kwe-galvanizing ebandayo kubushelelezi futhi kukhanyayo. Isendlalelo se-electroplating esinenqubo yokudlula umbala ngokuyinhloko siphuzi futhi siluhlaza, sinemibala eyisikhombisa. Isendlalelo se-electroplating esinenqubo emhlophe yokudlula simhlophe okwesibhakabhaka, futhi sinemibala kancane endaweni ethile yokukhanya kwelanga. Kulula ukukhiqiza "ukushiswa kukagesi" emakhoneni nasemaphethelweni enduku eyinkimbinkimbi, okwenza ungqimba lwe-zinc kule ngxenye lube lukhulu. Kulula ukwenza okwamanje ekhoneni langaphakathi futhi ukhiqize indawo empunga engaphansi kwamanje, okwenza ungqimba lwezinc kule ndawo lube mncane. Induku kufanele ingabi negaxa le-zinc kanye ne-agglomeration.
Ukubonakala kwamagalvanizing ashisayo kulukhuni kancane kunalokhu okubandayo, futhi kumhlophe okwesibhakabhaka. Ukubukeka kulula ukukhiqiza izimpawu zamanzi zenqubo kanye namaconsi ambalwa, ikakhulukazi ekupheleni kwenduku.
Ingqimba ye-zinc yokufaka uthayela oshisayo okumaholoholo iwugqinsi izikhathi eziningi kune-galvanizing ebandayo, futhi ukumelana nokugqwala kwayo kuyizikhathi eziningi kunaleyo yokufaka ugesi kagesi, futhi intengo yakhona ngokwemvelo iphakeme kakhulu kunaleyo yokufaka ama-galvanizing abandayo. Kodwa-ke, ngokuhamba kwesikhathi, i-galvanizing eshisayo evimbela ukugqwala iminyaka engaphezu kwe-10 izobe idume kakhulu kune-galvanizing ebandayo ngokuvimbela ukugqwala iminyaka engu-1-2 kuphela.
2. Inqubo
I-Cold galvanizing, eyaziwa nangokuthi i-galvanization, iwukusebenzisa okokusebenza kwe-electrolytic ukufaka induku esixazululweni esiqukethe usawoti we-zinc ngemva kokukhipha amafutha nokucoca, bese uxhuma isigxobo esinegethivu sempahla ye-electrolytic. Faka ipuleti le-zinc ngakolunye uhlangothi lwenduku ukuze ulixhume esigxotsheni se-electrolytic, uxhume ugesi, futhi usebenzise ukunyakaza okuqondisayo kwamandla ukusuka esigxotsheni kuya esigxotsheni esinegethivu ukuze ufake ungqimba lwezinc. ku-workpiece; I-hot galvanizing iwukukhipha uwoyela, ukugeza i-asidi, ukucwilisa umuthi bese womisa ucezu lokusebenzela, bese ucwilisa engxube ye-zinc encibilikisiwe isikhathi esithile, bese uyikhipha.
3. Isakhiwo sokumboza
Kukhona ungqimba lwe-brittle compound phakathi kwe-coating kanye ne-substrate ye-galvanizing eshisayo, kodwa lokhu akunawo umthelela omkhulu ekuphikisweni kwayo kokugqwala, ngoba ukumbozwa kwayo kuyi-zinc ehlanzekile, futhi ukumboza kufana ngokufanayo, ngaphandle kwama-pores, futhi akukona. kulula ukugqwala; Kodwa-ke, ukumbozwa kwama-galvanizing abandayo kwenziwa ngama-athomu athile e-zinc, okuyingxenye yokunamathela ngokomzimba. Kunezimbotshana eziningi phezulu, futhi kulula ukuthintwa indawo ezungezile nokugqwala.
4. Umehluko phakathi kwalokhu okubili
Emagameni alaba ababili, kufanele sazi umehluko. I-Zinc emapayipini ensimbi abandayo ensimbi itholakala ekamelweni lokushisa, kuyilapho i-zinc ekugayeleni okushisayo itholakala ku-450 ℃ ~ 480 ℃.
5. Ukuqina kwe-coating
Ugqinsi olubandayo lwe-galvanizing coating ngokuvamile luyi-3 ~ 5 μ m kuphela. Kulula kakhulu ukucubungula, kodwa ukumelana kwayo nokugqwala akukuhle kakhulu; I-hot-dip galvanized coating ngokuvamile ino-10 μ Ukumelana nokugqwala kogqinsi lwe-m nangaphezulu kungcono kakhulu, okungaba izikhathi eziphindwe kaningi kune-cold-galvanized pole.
6. Umehluko wamanani
Ukugalela amanzi okushisayo kuyinkinga kakhulu futhi kufuna kakhulu ekukhiqizeni, ngakho-ke amanye amabhizinisi anemishini emidala kanye nezinga elincane ngokuvamile asebenzisa imodi ebandayo yokufaka uthayela ekukhiqizeni, ephansi kakhulu ngentengo nezindleko; Nokho,abakhiqizi be-hot-dip galvanizingngokuvamile zihlelekile futhi zikhulu ngezinga. Banokulawula okungcono kwekhwalithi kanye nezindleko eziphakeme.
Umehluko ongenhla phakathi kokufaka amalahle ashisayo kanye nokufaka uthayela okubandayo kwezigxobo zezibani zasemgwaqweni zakwabiwa lapha. Uma izigxobo zezibani zasemgwaqweni zelanga zizosetshenziswa ezindaweni ezisogwini, kufanele zicabangele ukumelana komoya nokumelana nokugqwala, futhi zingadali iphrojekthi yokulahla udoti ngenxa yobugovu besikhashana.
