Ugesi ophehliwe:
Insimbi kulula ukugqwala emoyeni, emanzini noma enhlabathini, noma ilimale ngokuphelele.Ukulahlekelwa kwensimbi kwaminyaka yonke ngenxa yokugqwala kubala cishe i-1/10 yayo yonke insimbi ephumayo.Ngaphezu kwalokho, ukuze unikeze ubuso bemikhiqizo yensimbi kanye nezingxenye umsebenzi okhethekile, ngenkathi ubanikeza ukubukeka kokuhlobisa, ngokuvamile baphathwa nge-electro-galvanizing.
① Isimiso:
Njengoba i-zinc ingelula ukuhluka emoyeni owomile, emoyeni onomswakama, indawo engaphezulu ingakhiqiza ifilimu ye-carbonate eminyene kakhulu, engavikela ngokuphumelelayo ingaphakathi lingasagqwali.
② Izici zokusebenza:
1. I-zinc enamathelayo iwugqinsi, inamakristalu amahle, iyafana futhi ayinakho ukuqina, futhi ukumelana nokugqwala okuhle;
2. Ungqimba lwezinc olutholwe nge-electroplating lumsulwa ngokuqhathaniswa, futhi lugqwala kancane enkungu ye-asidi, i-alkali, njll., futhi lungavikela ngempumelelo i-substrate yensimbi;
3. I-zinc coating idluliswa yi-chromic acid ukuze yakhe emhlophe, enemibala, eluhlaza okwesibhakabhaka, njll, enhle futhi ehlobisa;
4. Ngenxa yokuthi i-zinc coating ine-ductility enhle, ingakhiwa ngokushaya okubandayo, ukugoqa, ukugoba, njll ngaphandle kokulimaza ukugqoka.
③ Ububanzi bohlelo lokusebenza:
Ngokuthuthuka kokukhiqizwa kwesayensi nezobuchwepheshe, izinkambu ezihilelekile embonini ye-electroplating ziye zanda kakhulu.Njengamanje, ukusetshenziswa kwe-electro-galvanization kuye kwasakazeka eminyangweni ehlukahlukene yokukhiqiza nokucwaninga.
Ama-galvanized ashisayo:
Ⅰ.Uhlolojikelele:
Endleleni yokumboza ye-matrix yensimbi evikelekile ehlukahlukene, idiphu elishisayo lihle kakhulu.Kusesimweni lapho i-zinc inguketshezi, ngemuva kwe-physics eyinkimbinkimbi, amakhemikhali, hhayi nje ungqimba oluqinile lwe-zinc olungagcini nje ngokucwecwa ensimbi, kodwa futhi ungqimba lwe-zinc-ferrous.Le ndlela yokucwenga ayigcini nje ngokuba nesici sokumelana nokugqwala kwe-galvanization kagesi, kodwa futhi ngenxa yongqimba lwe-zinc iron alloy.Futhi inokumelana okuqinile ne-zinc electroplated.Ngakho-ke, le ndlela yokucwenga ifaneleka ngokukhethekile indawo edlayo enamandla njengezinhlobonhlobo ze-asidi eqinile, inkungu ye-alkaline.
Ⅱ.Isimiso:
I-hot-dip galvanized layer iyi-zinc oketshezini lokushisa eliphezulu, futhi yenziwa ngezinyathelo ezintathu:
1. I-iron-based surface ichithwa yisisombululo se-zinc ukwenza isigaba se-zinc-ferrous;
2. Ama-ion e-zinc ongqimbeni lwe-alloy aphinde asakazwe ku-substrate ukuze akhe ungqimba lwe-zinc iron intercollation;
3. ubuso be-alloy layer bufakwe kungqimba lwezinc.
Ⅲ.Izici zokusebenza:
(1) Inesendlalelo se-zinc esiqinile esiminyene ngaphezulu endaweni yensimbi, egwema ukuthintana kwe-matrix yensimbi kunoma yisiphi isixazululo sokugqwala ukuze kuvikelwe i-matrix yensimbi ekugqwaleni.Emkhathini ojwayelekile, ingaphezulu le-zinc layer yakha ungqimba oluncane lwe-zinc oxide layer encane futhi esondelene, okunzima ukuncibilika emanzini, ngakho-ke i-matrix yensimbi idlala umphumela othile wokuvikela.
(2) Ngensimbi-zinc ingxubevange ungqimba, kuhlangene aminyene, ku zasolwandle usawoti humex emkhathini nomoya wezimboni wabonisa ukumelana ukugqwala esiyingqayizivele;
(3) Njengoba inhlanganisela iqinile, i-zinc-iron iyancibilika, inokumelana nokugqoka okuqinile;
(4) Njengoba i-zinc ine-ductility enhle, ungqimba lwe-alloy lunamathele ngokuphephile eqenjini lensimbi, ngakho-ke izingxenye ezishisayo zokucwenga zingabanda, zigoqwe, zixutshwe, zigobe, nokunye okunjalo ngaphandle kokulimaza ukugqoka;
(5) Ngemva kokushisa okushisayo kwe-finisse yensimbi, kufana nokwelashwa kwe-annealing, okungathuthukisa ngokuphumelelayo izakhiwo zemishini ye-matrix yensimbi, ukuqeda ukucindezeleka kwensimbi yokubumba insimbi, enenzuzo ekuphenduleni ilungu lesakhiwo sensimbi.
(6) Ubuso bezingcezu ngemva kokushisa okushisayo buyakhanya futhi buhle.
(7) Ungqimba oluhlanzekile lwezinc luwungqimba olunamathayela epulasitiki-plastic-plated kakhulu kumagalanisi ashisayo, olusondele kakhulu ku-zinc ehlanzekile, i-ductility, ngakho luyagobeka.
Ⅳ.Ububanzi besicelo:
Ukusetshenziswa kwe-hot-dip ghanelyly ukuthuthukiswa kwezimboni nezolimo.Ngakho-ke, imikhiqizo ye-hot-dip ghared iyizimboni (ezifana nemishini yamakhemikhali, ukucubungula uwoyela, ukuhlola olwandle, isakhiwo sensimbi, ukulethwa kukagesi, ukwakhiwa kwemikhumbi, njll.), ezolimo (ezifana: ukufafaza), izakhiwo (ezifana nokulethwa kwamanzi negesi, i-wire set Ishubhu, isikafula, indlu, njll.), ibhuloho, ezokuthutha, njll. isetshenziswe eminyakeni embalwa yakamuva.
Njengoba imikhiqizo yama-hot-dip galvanized inokubukeka okuhle, ukusebenza kahle kokumelana nokugqwala, ububanzi bokusebenza kwayo buya ngokuya buba banzi.
