1, impahla enkuluucingo lukathayela: ingot ye-zinc: akufanele ibe ngaphansi kwe-zinc engu-1 eshiwo ku-GB470;I-Sulfuric acid: i-grade 1 igxilile i-sulfuric acid ngokusho kwe-GB534;I-Hydrochloric acid: i-grade 1 igxilile i-hydrochloric acid ngokuhambisana ne-GB534;I-Ammonium chloride: kufanele ihambisane nezinhlinzeko ze-GB2946 ammonium chloride level 1.
2, ukubukeka: enamathela surface okuqhubekayo futhi ezingokoqobo, bushelelezi;Ukufakwa nokubopha izingxenye ezipuletiwe akuvunyelwe ukuba nokugeleza okulengayo, ukuconsa noma ukuncibilika.Ubuso bezingxenye ezipuletiwe ngeke bube nezinkinga ezifana nokuvuza kwensimbi kanye nensimbi yamazolo, kodwa ukukhubazeka kuvunyelwe ukuba khona ngaphansi kwezimo ezilandelayo;Indawo evuzayo ingaphansi kuka-0.5mm ububanzi bezindawo;Kungakhathaliseki ukuthi ucezu lokucwenga lungakanani, amachashaza asendaweni yokucwebeza echibini engu-0.5mm- Imm ububanzi akumele eqe amaphuzu ama-3 ngesentimitha-skwele, futhi ingqikithi yenani lamachashaza ocezwini lokucwenga ngeke lidlule amaphuzu ayi-10;Ku-engeli engaxhumeki noma engahlangani, ubude bokuthopha okulengayo obungekho ngaphezu kuka-1.5mm noma i-slag;Kunezibazi lapho izingxenye ze-plating zithintana namathuluzi okulenga namathuluzi okusebenza, kodwa ayikho insimbi yamazolo.
3. Ukunamathela kwe-Zinc kanye nogqinsi lwezingqimba ze-zinc: lapho ubukhulu bezingxenye ezipuletiwe buyi-3mm ~ 4mm, ukunamathela kwe-zinc kufanele kube ngaphansi kuka-460g/m, okungukuthi, ubukhulu obujwayelekile be-zinc layer abukho ngaphansi kuka-65um;Lapho ubukhulu bezingxenye ezipuletiwe bukhulu kuno-4mm, ukunamathela kwe-zinc akufanele kube ngaphansi kuka-610g/m, okungukuthi, ubukhulu obujwayelekile be-zinc layer abukho ngaphansi kuka-86um;Ukufana kwe-coating,othayelaungqimba ngokuyisisekelo iyunifomu nge yethusi sulfate isisombululo test etching izikhathi ezinhlanu kungekho insimbi amazolo;Ukunamathela kokunamathela, ungqimba lwezinc lwezingxenye ezipuletiwe kufanele luhlanganiswe ngokuqinile nensimbi eyisisekelo enamandla okwanele okunamathela, ngemuva kokuhlolwa kwesando kungawi, hhayi i-convex.
4, izidingo plated: kufanele plated surface kufanele kube bushelelezi, ngaphandle pickling indlela ayikwazi ukususa ukungcola, ezifana uwoyela ukufunda, amafutha, usimende, asphalt kanye nezinye ukungcola eziyingozi;Wonke ama-welds amalungu ashiselwe azovalwa ngaphandle komoya;Amapayipi neziqukathi kumele zibe nezimbobo zokukhipha umoya kanye nokuthatha i-zinc;I-workpiece izoqedwa ipayipi lensimbi elihlanganisiwe ngaphandle kwentambo, uma intambo izovikelwa.Indlela yokuhlola: Ukunamathela kwe-zinc kukalwa ngegeji yokujiya kazibuthe futhi ukujiya kongqimba lwezinc kukalwa ngokuqondile.Ukufana kokunamathela kunqunywe indlela yokuhlola i-copper sulfate solution etching.
I-5, indlela yokwelula: ukunamathela kongqimba lwe-zinc, ukujiya kwengqimba ye-zinc, ukufana kwesendlalelo se-zinc, ukunamathela kuyaphikiswa, thatha isampula nomkhiqizo ngaphansi kwemibandela efanayo yenquboothayela;Yenza ukuhlolwa, ungahlangabezani nezidingo zaleli zinga lemikhiqizo engafanelekile;Indlela yokuhlola isampula yesampula yomkhiqizo, okokuqala ngqa ngeke ibe necala, bese ngokuya ngezinhlinzeko ezifanele zokuhlolwa kwesampula, uma ingakafaneleki, yahlulele leli qoqo lemikhiqizo alifanelekile.Ibhange lomhloli: Izingxenye ezifanelekayo ezinamapuleti zingafakwa ohlwini kuphela ehhovisi eliqeqeshiwe ngemva kokuqinisekiswa komhloli wesikhathi esigcwele;Imikhiqizo efanelekile kufanele ipakishwe ngobunono ngokuya ngemininingwane ehlukahlukene.
