Izindaba

1. Ububanzi obusebenzayo
Izinhlelo zokusebenza ezibalulekile zei-hot-dip ifakwe ama-galvanizedamashidi asemikhakheni efana nezimoto, izinto zikagesi zasendlini, ezokwakha ubunjiniyela, okokusebenza kwemishini, izinto zikagesi, nezimboni zokukhanya.
2. Isizathu esiyinhloko sokuwa kongqimba lwezinki
Izinto eziyinhloko ezenza ungqimba lwezinki liwe luhlanganisa ukukhiqizwa nokukhiqizwa kwezinto ezingavuthiwe, kanye nokukhiqizwa nokucutshungulwa okungafani.Ngenxa ye-oxidation ebusweni, izinhlanganisela ze-silicon, umoya ophezulu we-oxidation kanye ne-protective gas dew point esigabeni se-NOF sezinto zokusetshenziswa, isilinganiso esingenangqondo sikaphethiloli womoya, izinga eliphansi lokugeleza kwe-hydrogen, ukungena kwe-oxygen esithandweni, izinga lokushisa eliphansi lensimbi ye-strip engena ebhodweni. , izinga lokushisa eliphansi lesithando somlilo sesigaba se-NOF, ukuhwamuka kukawoyela okungaphelele, okuqukethwe kwe-aluminium ephansi ebhodweni le-zinc, isivinini seyunithi esheshayo, ukunciphisa okunganele, isikhathi esifushane sokuhlala oketshezini lwe-zinc, kanye ne-coating ewugqinsi.Ukucubungula ukungafani kuhlanganisa irediyasi egobayo engahambisani, ukuguga kwesikhunta, ukukhuhla, ukususa isikhunta kukhulu kakhulu noma kuncane kakhulu, ukuntuleka kowoyela wokugcoba isigxivizo, kanye nesikhathi eside sokusebenza kwesikhunta esingakalungiswa noma singakalungiswa.
3. Izinto ezibalulekile ezidala ukugqwala okumhlophe yizi
(1) Ukunganyakazi kahle, ukushuba kwefilimu enganele noma engalingani;
(2) Ingaphezulu aligcotshwanga ngamafutha;
(3) Umswakama osele phezu kwensimbi egoqiwe ebandayo;
(4) I-passivation ayimiswanga kahle;
(5) Ngesikhathi sokuthutha noma ukugcinwa, ukubuya komswakama noma imvula iyancipha:
(6) Isikhathi sokugcina semikhiqizo eqediwe side kakhulu;
(7)Ishidi elishisayo lokucwilisaixhumene noma igcinwe kanye nezinye izinto ezonakalisayo njengama-asidi aqinile nama-alkali.
Ukugqwala okumhlophe kungase kuguquke kube amachashazi amnyama, kodwa amachashazi amnyama angase angabangelwa ukugqwala okumhlophe kuphela, njengamachashaza amnyama ashayisanayo.
4. Isikhathi esiphezulu esivumelekile sokulondoloza
Uma ukugcoba, ukupakisha, ukugcinwa kwempahla, kanye nempahla kwenziwa ngesikhathi, eminye imikhiqizo ingagcinwa isikhathi esingaphezu konyaka owodwa, kodwa kungcono ukuyisebenzisa ezinyangeni ezintathu.Uma kungabikho ukugcoba, isikhathi sifushane ukuvimbela i-air oxidation ebangelwa ukugcinwa isikhathi eside kakhulu.Isikhathi sangempela sokulondoloza kufanele sisekelwe kumkhiqizo ofana nomkhiqizo wangempela.
5. Izimiso Eziyisisekelo Zokugcinwa Kwezingqimba Zinc
Ezindaweni zemvelo ezonakalisayo, i-zinc ibeka phambili ukugqwala okusabalalisa ngaphezu kwensimbi, ngaleyo ndlela igcine isisekelo sensimbi.Mayelana nokumelana nokugqwala, ungqimba lwezinc luzokwenza ifilimu ethile evikelayo endaweni eyomile ukuze kugwenywe ukugqwala komoya ngokushesha, kubambezele izinga lokugqwala, futhi kungaxutshwa ngopende we-zinc powder ngesikhathi sokulungiswa ukuze kugwenywe ukugqwala kwensimbi nokuqinisekisa izakhiwo ezingokomzimba kanye nokugqwala. izici zokuphepha zedatha.
6. Izimiso Eziyisisekelo Zokudlula
Isixazululo se-Chromium trioxide passivation seshidi lediphu elishisayo lingakhiqiza ifilimu emise okwensimbi.I-chromium e-trivalent emndenini we-saturated solution passivation inzima ukuyincibilika emanzini omile, izakhiwo zayo ezingokomzimba azikhanyi, futhi inomphumela wokubumba.I-chromium eyi-hexavalent emndenini we-passivation incibilika ku-electrolyte eqinile, engaba nomthelela omise okwensimbi uma ifilimu ye-passivation iklwejwa, futhi ibe nomthelela wokuphulukisa wefilimu emise okwensimbi.Ngakho-ke, ngokwezinga elithile, ifilimu ye-passivation ingavimbela isitimu noma igesi ebandayo emanzi ukuthi ingagqwali ngokushesha ishidi le-hot-dip galvanized, lidlale indima yokunakekela.
7. Indlela yokusebenza kokumelana nokugqwala
Kunezindlela ezintathu zokuhlola ukumelana nokugqwala kweashisayo-dip amashidi:
(1) Ukuhlolwa kwesifutho sikasawoti;(2) Ukulinga okubandayo okumanzi;(3) Ukuhlolwa kokugqwala.
