I-hot-dip galvanizing iyindlela evamile yokuvikela ukugqwala kwensimbi.Icwilisa imikhiqizo yensimbi oketshezini oluncibilikisiwe lwe-zinc ukuze kwakhe ungqimba lwengxubevange ye-zinc-iron kanye nongqimba oluhlanzekile lwe-zinc ebusweni bensimbi, ngaleyo ndlela inikeze isivikelo esihle sokugqwala.Le ndlela isetshenziswa kabanzi ekwakheni, imoto, amandla, ukuxhumana nezinye izimboni ukuvikela izakhiwo zensimbi, amapayipi, izinsimbi, njll.
Izinyathelo eziyisisekelo zenqubo ye-hot-dip galvanizing yilezi ezilandelayo:
Ukususa amafutha nokuhlanza
Indawo yensimbi kuqala idinga ukuhlanzwa kahle ukuze kukhishwe amafutha, ukungcola nokunye ukungcola.Lokhu kuvame ukwenziwa ngokucwilisa insimbi kusisombululo esine-alkaline noma esine-asidi elandelwa ukugeza ngamanzi abandayo.
I-Flux coating
Insimbi ehlanziwe bese icwiliswa ku-30% yesisombululo se-zinc ammonium ku-65-80.°C.Inhloso yalesi sinyathelo ukusebenzisa ungqimba lwe-flux ukusiza ukususa ama-oxide ebusweni bensimbi nokuqinisekisa ukuthi i-zinc encibilikisiwe ingasabela kangcono ngensimbi.
I-galvanizing
Insimbi icwiliswa ku-zinc encibilikisiwe ekushiseni okungaba ngu-450°C. Isikhathi sokucwiliswa ngokuvamile siyimizuzu emi-4-5, kuye ngosayizi kanye ne-inertia eshisayo yensimbi.Phakathi nale nqubo, ingaphezulu lensimbi lihlangana ngamakhemikhali ne-zinc encibilikisiwe.
Ukupholisa
Ngemuva kokufakwa kwe-hot-dip galvanizing, insimbi idinga ukupholiswa.Ukupholisa umoya wemvelo noma ukupholisa ngokushesha ngokucisha kungakhethwa, futhi indlela ethile incike ezidingweni zokugcina zomkhiqizo..
I-hot-dip galvanizing iyindlela ephumelelayo yokwelapha ukubola kwensimbi, enikeza izinzuzo ezibalulekile:
●Izindleko eziphansi: Izindleko zokuqala nezesikhathi eside ze-hot-dip galvanizing ngokuvamile ziphansi kunezinye izindwangu zokulwa nokugqwala, okwenza kube ukukhetha okuthengekayo.
●Impilo yesevisi ende kakhulu: Uthayela ungavikela insimbi ngokuqhubekayo iminyaka engaphezu kwengu-50 futhi umelane ngempumelelo nokugqwala.
●Ukunakekelwa okuncane okudingekayo: Njengoba i-galvanized coating iyazinakekela futhi ishubile, inezindleko eziphansi zokunakekela kanye nempilo ende yesevisi.
●Ivikela ngokuzenzakalelayo izindawo ezilimele: I-galvanized coating inikeza ukuvikelwa komhlatshelo, futhi izindawo ezincane zomonakalo azidingi ukulungiswa okwengeziwe.
●Isivikelo esigcwele nesiphelele: I-Hot-dip galvanizing iqinisekisa ukuthi zonke izingxenye, kuhlanganise nezindawo okunzima ukufinyelela kuzo, zivikelekile ngokugcwele.
●Kulula ukuhlola: Isimo se-galvanized coating singahlolwa ngokuhlola okubonakalayo okulula.
●Ukufakwa okusheshayo:Imikhiqizo yensimbi efakwe i-hot-dip galvanized isilungele ukusetshenziswa lapho ifika endaweni yomsebenzi, ngaphandle kokulungiswa kwendawo eyengeziwe noma ukuhlolwa okudingekayo.
● Isicelo esisheshayo se-coating egcwele: Inqubo ye-hot-dip galvanizing iyashesha futhi ayithinteki isimo sezulu, iqinisekisa ukuguqulwa okusheshayo.
Lezi zinzuzo zenza i-hot-dip galvanizing ibe yisinqumo esifanele sokuvikela ukugqwala kwensimbi, okungathuthukisi nje impilo yesevisi nokusebenza kwensimbi, kodwa futhi kunciphisa izindleko zizonke kanye nomthwalo wokulungisa umsebenzi.
Izindawo eziveziwe zokufakwa ekugcineni (okuhlanganisa ubuso be-flange) be-Ukumunca uwoyela we-CDSR nokukhipha amapayipizivikelwe ngokufaka ugesi oshisayo ngokuhambisana ne-EN ISO 1461, ekugqwaleni okubangelwa amanzi olwandle, inkungu kasawoti kanye nendawo yokudlulisela.Njengoba imboni kawoyela negesi iqhubeka nokuphishekela intuthuko esimeme, ukusetshenziswa kobuchwepheshe be-hot-dip galvanizing akugcini nje ukuthuthukisa ukumelana nokugqwala kwemishini futhi kwandise impilo yayo yokusebenza, kodwa futhi kunciphisa ngokungaqondile ukusetshenziswa kwezinsiza kanye nokuphehla imfucuza ngokunciphisa imvamisa yokushintshwa kwemishini. ngenxa yokugqwala.
