Ukuqhathaniswa Kwezinto Zokusetshenziswa Zensimbi: I-Galvanized Q195, I-Galvanized Q235, DX51D+Z & 304 Stainless Steel
Ukuqina kwezinsimbi, izintambo, kanye nezimbazo zesilingi, ukusebenza kokugoba, impilo yokuvikela ukugqwala, kanye nezindleko ezithintekayo kuyo yonke iphrojekthi kunqunywa izigaba zensimbi eyisisekelo. Zonke izinsimbi zikakhabhoni ezisetshenziswe kulesi sihloko zisebenzisa imikhiqizo eqedwe ngogalvanized yefekthri ukuze kuqhathaniswe kahle, kususwe ukwehluka kokusebenza okubangelwa insimbi engamboili engenayo i-anti-rust coating. Izinto ezine eziyinhloko zokusetshenziswa kwezinsimbi ezine-galvanized ezisetshenziswa kabanzi ekwenziweni kwamabhodi ezindonga emhlabeni wonke: i-galvanized Q195, i-galvanized Q235, i-DX51D+Z continuous hot-dip galvanized steel, i-304 stainless steel. Kusekelwa izindinganiso ze-GB/T 700, EN 10346, ASTM A653, kanye ne-SSMA cold-formed steel, lesi sihloko siqhathanisa izinkomba zemishini, ukumelana nokugqwala, izimo zokwakha, kanye nezindleko zokusebenza isikhathi eside, kusiza abasubathi nabathengi bomhlaba wonke ukuba bagweme ubungozi bokungafani kwezinto.Umtapo Wezincwadi Wezobuchwepheshe Wensimbi Ebunjwe Ngokubandayo (Isixhumanisi Esisemthethweni Esisebenzayo)
1. Amapharamitha Emishini Nezamaminerali Ezinto Eziyisisekelo Ezine Zegwalisiwe
Insundu Yensimbi Engu-Q195 Enomsizi Ophansi
Amandla okukhiqiza ayisisekelo ≥195MPa, okuqukethwe kwekhabhoni ≤0.12%, ukunwebeka okuphezulu kakhulu. Amakhoyili aqedwe nge-electro-galvanized noma i-light hot-dip galvanized (Z60-Z100) angawona ajwayelekile. Ukusebenza okuhle kakhulu kokugoba okubandayo ngaphandle kokuqhekeka ngesikhathi sokugoqa okuyinkimbinkimbi kwe-keel. Imikhawulo: Amandla okudonsa aphansi, ukugqoka kwe-zinc okuncane kuholela ekumeleni okubuthakathaka okubhekene nesifutho sikasawoti, impilo emfushane ezindaweni ezinomswakama. Isetshenziswa ikakhulukazi ezindaweni zangaphakathi zesikhashana ezingabizi kakhulu.
Insundu Yensimbi Engu-Q235B Yezakhiwo
Amandla okukhiqiza ayisisekelo ≥235MPa, amandla okudonsa 360–510MPa, ukuguquguquka okulinganiselayo nokumelana nomthelela. Itholakala ngezinketho ze-electro-galvanized ne-hot-dip galvanized Z120-Z180. Ukuqina kwezakhiwo okuphezulu kune-galvanized Q195, amandla okuthwala omthwalo avikelekile ezindongeni ezijwayelekile zokuhlukanisa. Ukugqoka kwe-zinc emaphakathi kuletha ukusebenza okumaphakathi kokulwa nomhlwa, kusetshenziswa kabanzi ezindaweni zokwakha ezimaphakathi.
Insundu Yensimbi Egalevaniswe Ngokushisayo (DX51D+Z) (EN10346, Iyafana ne-ASTM A653 G90)
I-substrate egalevaniswe ngokukhethekile yokubumba abandayo, i-galvanization eqhubekayo egalevaniswe ngokushisayo eyenziwe efektri enesisindo sezinkwa esijwayelekile se-Z180/Z275. Isisekelo singaba insimbi eluhlaza ye-Q195 noma i-Q235, enesendlalelo sezinkwa esiqinile nesijulile esakhiwe ngaphansi kwezinga lokushisa eliphezulu. Izuza ibhalansi ephelele phakathi kwekhono lokubumba, amandla esakhiwo, nokumelana nokugqwala, impahla eluhlaza eqinisekisiwe yezinduku zensimbi ezihlala njalo zokuhlala nezokuhweba, ehambisana nekhodi yokwakha yomhlaba wonke yokuthekelisa.
Insundu Yensimbi Ye-Austenitic (304)
Iqukethe i-chromium engaphezu kuka-10.5% ukwakha ifilimu yokuzilungisa engavimbeli ukugqwala, ayidingi i-galvanization eyengeziwe. Ukumelana kahle nomusi kasawoti, umswakama ophezulu, kanye ne-acid & alkali ebuthakathaka. Impilo yesevisi idlula iminyaka engu-50 ezindaweni ezinokubola kakhulu. Amaphutha: Izindleko eziphezulu zezinto zokusetshenziswa, ukubuyela emuva okucacile ngemuva kokugoba okubandayo, izinga eliphezulu lokulahla lapho kucutshungulwa uma kuqhathaniswa ne-carbon steel e-galvanized. Isetshenziswa kuphela ezindaweni ezikhethekile zokwakha ezinezindawo ezinokubola kakhulu.

2. Ukuqhathanisa Okungokwezinhlangothi Eziningi
2.1 Ukusebenza Komshini Wokubumba Okubandayo
Ukukalwa ngokuvumelana nokuthambeka okubushelelezi & izinga eliphansi lokuchithwa: I-Galvanized Q195 > DX51D+Z > I-Galvanized Q235 > 304 Stainless Steel. I-Galvanized Q195 igcina ubuthakathaka bekhabhoni obuphansi kakhulu ngemuva kwe-galvanization, ilungele izimbazo ezincane eziyinkimbinkimbi ezikhethekile. I-DX51D igcina ukuguquguquka okuzinzile ngaphansi kokugqoka okujiyile kwe-zinc. I-Galvanized Q235 inokuqina okuyisisekelo okuphezulu ngokubuyela emuva okuncane kokugoba. Insalela yensimbi idinga ukubunjwa kwesibili ngemuva kokubunjwa, okwandisa izindleko zokukhiqiza.
2.2 Ukumelana Nokugqwala & Impilo Yesevisi (Konke Okujwayelekile Okuhlanganisiwe Kwensimbi Ye-Carbon E-Galvanized)
Ukukalwa kokumelana nesifutho sikasawoti: 304 Stainless Steel >> DX51D+Z Z275 > DX51D+Z Z180 > I-Galvanized Q235 (Z120-Z180) > I-Galvanized Q195 (Z60-Z100)

- DX51D+Z Z275: ≥720h NSS ukufafaza usawoti, ukusetshenziswa okuzinzile kweminyaka engaphezu kwengu-30 ezindaweni ezisogwini, ezingaphansi komhlaba, nasezindaweni ezinomswakama omkhulu zokuhweba.
- Insundu Engu-304: Ukumelana okungenamkhawulo nomswakama osawolintshi, iminyaka engu-50+ yokuphila ezindaweni zasolwandle, echibini lokubhukuda kanye nezindawo zezokwelapha.
Isithombe 2: Umfanekiso wokuhlola we-lab ohlanganisa ububanzi bokufaka i-zinc bokufaka i-galvanized Q195, i-galvanized Q235 kanye ne-DX51D+Z
2.3 Izindleko Zokuphila Ngokugcwele
Intengo yeholo ukusuka phezulu kuya phansi: I-Galvanized Q195 < I-Galvanized Q235 < DX51D+Z Z180 < DX51D+Z Z275 < Insimbi Engagqwali ye-304
- I-Galvanized Q195: Izindleko zokwakha eziphansi, ukufakwa kwe-zinc okuncane kuholela ekugcinweni okuphindaphindiwe phakathi neminyaka eyi-10; kuphela okungabiza kahle kumaphrojekthi wesikhashana afushane.
- I-Galvanized Q235: Izindleko zokwakha eziphakathi, ukufakwa kwe-zinc okuphakathi kwehla izikhathi zokugcinwa, kufanelekile ukuze kuhlaziywe kwezohwebo okwesikhashana esiphakathi neminyaka eyi-10–15.
- Uhlaka lwe-DX51D+Z: Iphaneli ye-zinc efakwe ngokushisa ikhipha ukugcinwa okujwayelekile kokuvikela ukugqwala; I-Z275 inezindleko zokuqala eziphakeme kancane kodwa izindleko zokulungisa zikhathi ezide zinciphile, ukukhetha okungabiza kahle kakhulu kokwakhiwa okungapheli.
- 304 Stainless Steel: Intengo elingelungile 3.5–5 izikhathi DX51D Z275, kuphela okungabiza kakhulu kumaphrojekthi akhethekile okuphikisana nokugqwala.
Isithombe 3: Ithebula lokuhlonza ubunjalo bokwakha elihlanganisa amandla okukhishwa, isisindo sokufaka i-zinc, amahora okukhanya kwensipho, impilo yesevisi kanye nezindleko zokuphila okuphelele, idatha evela ku-GB/T 11981, EN 10346, ASTM B117
3. Umhlahlandlela Wokuhlangabezana Nezimo Ezijwayelekile (Zonke Igalvanized Carbon Steel)

4. Izimiso Eziyisisekelo Zokukhethwa Kwezinto
- Ukwakhiwa kwezindlu ezihlala njalo, amahhotela, izitolo ezinkulu nezakhiwo zamahhovisi kufanele kuqale uchungechunge lwe-DX51D+Z olushisayo olugcotshwe nge-hot-dip; i-galvanized Q195/Q235 ivunyelwe kuphela amaphrojekthi esikhashana anomjikelezo omfushane, hhayi izakhiwo ezihlala njalo isikhathi eside.
- Amaphrojekthi anesikhathi sokuphila esingaphezu kweminyaka engu-15 noma atholakala ezindaweni ezinomswakama, ezisogwini kufanele asebenzise insimbi engagqwalisiwe ye-DX51D Z275 noma 304; i-Q195 encane egqwalisiwe nge-zinc encane ayikwazi ukusetshenziswa.
- Izindonga ezithwala umthwalo osindayo, izindonga ezingaphezu kwamamitha angu-12 ukuphakama kanye nezindonga ezinokufakwa kwezinto ezinkulu zidinga izinsimbi ze-DX51D eziqiniswe nge-Q235 egqwalisiwe, esikhundleni sezinto eziyisisekelo ze-Q195 egqwalisiwe.
- Amaphrojekthi esikhashana anempilo yesevisi engaphansi kweminyaka emi-3 angakhetha i-Q195 egalevaniswe ukuze kulawulwe izindleko zokuqala zezinto, kodwa ukuhlolwa okujwayelekile kokuvimbela ukugqwala kufanele kugcinwe ezinhlelweni zokulungisa ezilandelayo.
Isiphetho
Insika ezishisayo ezigoqwe nge-DX51D+Z iyona nto eyinhloko ekwenzeni izinsika zensimbi nezokulenga isilingi ezisezingeni lomhlaba. Uma iqhathaniswa ne-Q195 ne-Q235 ezigoqwe nge-galvanized, iyathola ukulinganisela okungcono kokusebenza ekubunjweni okubandayo, ukuqina komklamo, namandla okumelana nokugqwala esikhathini eside. I-Q195 ne-Q235 ezigoqwe nge-galvanized kanye ne-304 stainless steel zisebenza kuphela ezindaweni ezikhethekile zokwakha ezinezimpilo ezicacile zemisebenzi nemikhawulo yemvelo. Abathengi nabakhi bakhiwo kufanele bakhethe izigaba zensimbi ezigoqwe nge-galvanized ngokusekelwe ezimpilweni zemisebenzi yephrojekthi, umswakama wangaphakathi, isidingo somthwalo, kanye nesabelomali sonke ukuze kugwenywe izingozi zekhwalithi yokugqwala nokuhlanekezela ezibangelwa ukukhethwa kwezinto ezingafanele.I-ASTM A653 Insundu Ehlanganiswe Ngogalvanizi: Ikhasi Elisemthethweni Lezinga
