Umahluko phakathi kwe-electro-galvanizing kunye ne-hot-dip galvanizing

Umphezulu wentsimbi ngokuqhelekileyo unomgca we-galvanized, onokuthi uthintele intsimbi ukuba ingagqwali ukuya kwinqanaba elithile.Umaleko owenziwe ngesinyithi wentsimbi ngokuqhelekileyo wakhiwe nge-galvanizing eshushu-dip okanye i-electro-galvanizing.Ngoko ke yintoni umahluko phakathieshushu-dip galvanizingkunye ne-electro-galvanizing?

Inkqubo yokuGalela iElectro

I-Electrogalvanizing, ekwabizwa ngokuba yi-galvanizing ebandayo kushishino, yinkqubo yokusebenzisa i-electrolysis ukwenza iyunifomu, isinyithi esishinyeneyo kunye nesibotshwe kakuhle okanye i-alloy deposition layer kumphezulu we-workpiece.

Xa kuthelekiswa nezinye iintsimbi, i-zinc yintsimbi enexabiso eliphantsi kwaye icoleka lula.Ixabiso eliphantsi le-anti-corrosion coating kwaye isetyenziswa ngokubanzi ukukhusela iindawo zentsimbi, ngakumbi ngokuchasene ne-atmospheric corrosion, kunye nokuhlobisa.Ubuchule bokufaka i-tank plating (okanye i-rack plating), i-barrel plating (kwiindawo ezincinci), i-blue plating, i-automatic plating kunye ne-continuous plating (ngocingo, i-strip).

Iimpawu ze-electro-galvanized

Injongo ye-electrogalvanizing kukuthintela izinto zetsimbi ukuba zingatshatyalaliswa, ukuphucula ukunyanzeliswa kwe-corrosion kunye nobomi benkonzo yensimbi, kwaye ngexesha elifanayo ukwandisa ukubonakala kokuhlobisa kwemveliso.Intsimbi iya kuba yimozulu, amanzi okanye umhlwa emhlabeni ngokuhamba kwexesha.Intsimbi ehlanjululwa minyaka yonke e-China ithatha malunga nesinye kwishumi sexabiso elipheleleyo lensimbi.Ngoko ke, ukwenzela ukukhusela ubomi benkonzo yentsimbi okanye iinxalenye zayo, i-electro-galvanizing isetyenziselwa ukucubungula insimbi.

Ekubeni i-zinc akulula ukuyitshintsha emoyeni owomileyo, kwaye inokuvelisa ifilimu ye-zinc carbonate eyisiseko kwindawo enomswakama, le filimu inokukhusela iindawo zangaphakathi kumonakalo wokubola, nokuba i-zinc layer yonakaliswa yinto ethile.Kwezinye iimeko, i-zinc kunye nentsimbi idibanisa ixesha elide ukwenza i-microbattery, kunye ne-matrix yensimbi ekhuselweyo njenge-cathode.Isishwankathelo I-Electrogalvanizing inezi mpawu zilandelayo:

1. Ukumelana ne-corrosion efanelekileyo, ukunyameka kunye nokudityaniswa okufanayo, akukho lula ukungenwa yigesi eyingozi okanye ulwelo.

2. Ngenxa yokuba i-zinc layer icocekile, akulula ukuba i-corrod kwi-asidi okanye i-alkali bume.Ukukhusela ngokufanelekileyo umzimba wentsimbi ixesha elide.

3. Emva kokupasa nge-chromic acid, ingasetyenziselwa imibala eyahlukeneyo, enokuthi ikhethwe ngokwezinto ezikhethwa ngabathengi.I-galvanizing ibukeka kwaye ihombise.

4. I-coating ye-zinc ine-ductility enhle kwaye ayiyi kuwela ngokulula ngexesha lokugoba, ukuphatha kunye nempembelelo.

Yintoni umahluko phakathi kwe-hot-dip galvanizing kunye ne-electro-galvanizing

Imigaqo yomibini yahlukile.I-Electrogalvanizing kukufaka i-galvanized layer phezu kwentsimbi ngendlela ye-electrochemical.I-Hot-dip galvanizingkukuntywilisela intsimbi kwisisombululo se-zinc ukwenza umphezulu wentsimbi kunye ne-galvanized layer.

Kukho umahluko kwinkangeleko phakathi kwezi zimbini.Ukuba intsimbi i-electro-galvanized, ubuso bayo bulula.Ukuba intsimbi ishushu-dip galvanized, ubuso bayo burhabaxa.Iingubo ze-electro-galvanized ziyi-5 ukuya kwi-30μm, kunye neentyantyambo zokudipha ezishushu zingu-30 ukuya kuma-60μm.

Umda wesicelo wahlukile, i-galvanizing eshushu-dip isetyenziswa kakhulu kwintsimbi yangaphandle efana neecingo zendlela, kwaye i-electro-galvanizing isetyenziswa kakhulu kwintsimbi yangaphakathi efana neepaneli.
