Ukuqhathanisa phakathi kwe-hot wire plating kanye ne-electro galvanizing

Ii-hot plating wireingakhiqiza uqweqwe olushubile, futhi kukhona kokubili ungqimba lwe-zinc oluhlanzekile kanye nongqimba lwe-iron-zinc alloy, ngakho-ke ukumelana nokugqwala kuhle.Amandla okukhiqiza e-hot dip galvanizing aphakeme kakhulu, futhi isikhathi sokuhlala sezingxenye ethangini lediphu elishisayo ngokuvamile aseqi i-lmin.Uma kuqhathaniswa ne-electrogalvanizing, i-hot-dip galvanizing inezindleko eziphansi zokukhiqiza kanye nomthelela omncane endaweni ezungezile kune-electroplating.Lapho kufakwa amapuleti, amabhande, izintambo, amashubhu namanye amaphrofayili, izinga lokuzenzakalelayo liphezulu.
Ukucwebezela kwediphu elishisayo “okumanzi” kubuye kubizwe ngokuthi “indlela yokuncibilikisa okuncibilikisiwe” idiphu elishisayo eliyi-galvanizing.Ngemuva kokuthi i-workpiece yensimbi igcotshwe, ifakwe emanzini anosawoti futhi ihlanzwe, kuyadingeka ukudlulisa "i-solvent encibilikisiwe" (eyaziwa nangokuthi i-co-solvent) ethangini elikhethekile elibekwe ngaphezu kwendawo encibilikisiwe ye-zinc, bese ufaka isisombululo se-zinc ukususa ukufakwa kwe-zinc.I-solvent encibilikisiwe ngokuvamile iyingxube ye-ammonium chloride ne-zinc chloride, kodwa amanye amasawoti e-chlorine nawo ayafakwa.

I-Dip galvanizing “eyomile” ibizwa nangokuthi “indlela yokuncibilikisa okomisa” i-hot dip galvanizing.Izinto zokusebenza ze-ayoni nensimbi ngokususa amafutha, ukucotshwa, ukuhlanza, isincibilikisi sosizo lokucwilisa futhi ngemva kokomiswa, bese zicwiliswa kusixazululo se-zinc esincibilikisiwe ukuze kuqhume.I-co-solvent ngokuvamile i-hydrochloric acid, i-ammonium chloride, noma ingxube ye-ammonium chloride ne-zinc chloride.
Ububanzi bokusetshenziswa: Ngenxa yokuthi ukunamathela okuwumphumela kushubile, i-hot-dip galvanizing inomsebenzi omuhle kakhulu wokuvikela kune-galvanizing kagesi, ngakho-ke kuwukusekela okubalulekile kwezingxenye zensimbi endaweni yokusebenza eqinile.Imikhiqizo efakwe i-hot-dip galvanized isetshenziswa kabanzi kumishini yamakhemikhali, ukucubungula i-petroleum, ukuhlola olwandle, isakhiwo sensimbi, ukuthuthwa kukagesi, ukwakhiwa kwemikhumbi neminye imisebenzi, emkhakheni wezolimo njengokunisela ngezibulala-zinambuzane, ukufudumeza kanye nokwakhiwa okufana nokuthuthwa kwamanzi negesi, ama-wire bushings. , i-scaffolding, amabhuloho, i-highway guardrail, njll., le minyaka kube yinani elikhulu labakhethiwe.
