I-hot-dip galvanizing ukwenza insimbi encibilikisiwe isabelane ne-iron matrix ukuze ikhiqize ungqimba lwengxubevange, ukuze i-matrix kanye nokunamathela kuhlanganiswe.I-hot-dip galvanizing iwukuba ugqume izingxenye zensimbi kuqala.Ukuze ususe i-iron oxide ebusweni bezingxenye zensimbi, ngemva kokukhetha, ihlanzwa ethangini le-ammonium chloride noma i-zinc chloride isixazululo samanzi noma isixazululo esinamanzi esixubile se-ammonium chloride ne-zinc chloride, bese sithunyelwa ediphini elishisayo. ithangi lokugqoka.I-hot-dip galvanizing inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile nokuphila isikhathi eside.
Izinto zensimbi ezisetshenziswa kakhulu embonini zizogqwala ziye kumazinga ahlukene uma zisetshenziswa ezindaweni ezifana nomkhathi, amanzi olwandle, inhlabathi nezinto zokwakha.Ngokwezibalo, ukulahlekelwa minyaka yonke kwezinto zensimbi emhlabeni wonke ngenxa yokugqwala kubala cishe i-1/3 yokukhiqizwa kwayo okuphelele.Ukuze kuqinisekiswe ukusetshenziswa okuvamile kwemikhiqizo yensimbi futhi kwandise impilo yabo yenkonzo, ubuchwepheshe bokuvikela ukugqwala kwensimbi buhlale buthola ukunakwa okubanzi.
I-hot-dip galvanizing ingenye yezindlela eziphumelela kakhulu zokubambezela ukugqwala kwemvelo kwensimbi nensimbi.Kuwukucwilisa imikhiqizo yensimbi neyensimbi okuvele kwayo kuhlanzwe futhi kwasebenza kusixazululo se-zinc esincibilikisiwe.Ingaphezulu limbozwe nge-zinc alloy coating ngokunamathela okuhle.Uma kuqhathaniswa nezinye izindlela zokuvikela insimbi, inqubo ye-hot-dip galvanizing inezici zokuvikela zenhlanganisela yesithiyo esingokomzimba kanye nokuvikelwa kwe-electrochemical kwe-coating, amandla okubopha okunamathelayo kanye ne-substrate, ukubumbana, ukuqina, ukunganakekeli kanye ukonga kwe-coating.Inezinzuzo ezingenakuqhathaniswa mayelana nokuguquguquka nokuvumelana nokuma nobukhulu bemikhiqizo.Njengamanje, imikhiqizo yamathayela ediphu eshisayo ikakhulukazi ihlanganisa amapuleti ensimbi, imicu yensimbi, izintambo zensimbi, amapayipi ensimbi, njll., okuyizingxenye ezinkulu kakhulu zamashidi ensimbi anamadiphu ashisayo.Isikhathi eside, inqubo yokufaka i-hot-dip galvanizing ibithandwa abantu ngenxa yezindleko zayo eziphansi zokucwenga, izindawo zokuvikela ezinhle kakhulu nokubukeka okuhle, futhi isetshenziswa kabanzi ezimotweni, ezakhiweni, ezintweni zikagesi zasendlini, amakhemikhali, imishini, uphethiloli, i-metallurgy, imboni elula , ezokuthutha, amandla kagesi, ezondiza kanye nobunjiniyela basolwandle kanye neminye imikhakha.
Izinzuzo zemikhiqizo yama-hot-dip galvanized yilezi ezilandelayo:
1. Yonke indawo yensimbi ivikelwe, kungakhathaliseki ukuthi ingaphakathi lepayipi elifaneleka ekucindezelekeni, noma kunoma iyiphi enye indawo lapho ukugqoka kunzima ukungena khona, i-zinc encibilikisiwe kulula ukumboza ngokulinganayo.
idiphu elishisayo liphehliwe
idiphu elishisayo liphehliwe
2. Inani lobulukhuni bongqimba oluthathiwe likhulu kunelensimbi.Isendlalelo esiphezulu se-Eta sinobunzima be-70 DPN kuphela, ngakho-ke kulula ukubola ngokungqubuzana, kodwa ungqimba oluphansi lwe-Zeta kanye nongqimba lwe-delta lune-179 DPN kanye ne-211 DPN ngokulandelanayo, ephakeme kunobulukhuni be-159 DPN bensimbi, ngakho umthelela wayo ukumelana nokumelana ne-Abrasion kuhle impela.
3. Endaweni yekhoneni, ungqimba lwe-zinc luvame ukushuba kunezinye izindawo, futhi lunokuqina okuhle nokumelana nokugqoka.Okunye okokumboza kuvame ukuba yi-thinnest, okunzima kakhulu ukwakha, kanye nendawo esengozini kakhulu kulelikhona, ngakho-ke ukunakekelwa kuvame ukudingeka.
4. Ngisho nangenxa yomonakalo omkhulu wemishini noma ezinye izizathu.Ingxenye encane yongqimba lwezinc izowa futhi isisekelo sensimbi sizovezwa.Ngalesi sikhathi, ungqimba lwezinc oluzungezile luzosebenza njenge-anode yomhlatshelo ukuvikela insimbi lapha ekugqwaleni.Okuphambene nalokho kuyiqiniso kwezinye izigqoko, lapho ukugqwala kwakha khona ngokushesha futhi kusakazeka ngokushesha ngaphansi kokugqoka, okwenza ukuba ukugqoka kucwebe.
5. Ukusetshenziswa kongqimba lwezinc emkhathini kuhamba kancane, cishe u-1/17 kuya ku-1/18 wezinga lokugqwala kwensimbi, futhi kuyabikezelwa.Ukuphila kwayo kudlula kude le kwanoma iyiphi enye into enamathelayo.
6. Ukuphila kokugqoka kuncike ebukhulu bokugqoka endaweni ethile.Ubukhulu be-coating bunqunywa ubukhulu bensimbi, okungukuthi, ukushuba kwensimbi, ukuqina kwe-coating, ngakho ingxenye yensimbi ewugqinsi yesakhiwo esifanayo sensimbi kufanele futhi ithole ukujiya ukuze kuqinisekiswe impilo ende. .
7. Ungqimba olunothayela lungapendwa ngohlelo lwe-duplex ngenxa yobuhle balo, ubuciko, noma uma lusetshenziswa endaweni ethile egqwala kakhulu.Uma nje uhlelo lwepende lukhethwe ngendlela efanele futhi ukwakhiwa kulula, umphumela walo wokulwa nokugqwala ungcono kunomdwebo owodwa kanye ne-hot-dip galvanizing.Ubude bempilo bungcono izikhathi ezingu-1.5~2.5.
8. Ukuze kuvikelwe insimbi ngongqimba lwezinki, kunezinye izindlela ezimbalwa ngaphandle kokufaka i-hot-dip galvanizing.Ngokuvamile, indlela yokufaka i-hot-dip galvanizing iyona esetshenziswa kakhulu, umphumela ongcono kakhulu wokunqanda ukugqwala kanye nenzuzo engcono kakhulu yezomnotho.
