Uyazi kabanzi ngezincazelo kanye nobukhulu bezinqwaba zensimbi zohlobo lwe-z?
Ukwenziwa Kwenqwaba Yeshidi Eliphezulu Lokwenziwa Kwenqwaba Yeshidi Lensimbi Eligoqiwe Elishisayo Elinohlobo lwe-Z
Ukubuka Konke Komkhiqizo
I-Royal Steel Group ihlinzekainqwaba yeshidi lensimbi engu-Z egoqwe ngokushisa kwezicelo zesisekelo, ezolwandle, zechweba, zokulawula izikhukhula kanye nengqalasizinda ezifunwa kakhulu. Nge-flange ebanzi kanye ne-Z-profile ephumelelayo leziIzinqwaba zamashidi anomumo ongu-Zukufeza i-modulus yesigaba esiphezulu, ukumelana nokugoba kanye nokusebenza kahle kwezinto zokwakha izindonga ezijulile kanye nezakhiwo zokugcina umhlaba ezihlala njalo noma zesikhashana.
OkwethuIzinqwaba zensimbi zohlobo lwe-Z kungakhiqizwa ngezindlela ezahlukeneamamaki ensimbi, amaphrofayili, ubudefuthiizinhlobo zokukhiyangokwezindinganiso zomhlaba wonke kanye nangokusekelwe ezimisweni zephrojekthi yakho.Ukuhlolwa Kobukhulu be-MTCfuthiUkuhlolwa Kweqembu LesithathuZiyatholakala.

Uhlobo lwe-Z Uhlobo lwe-Z Ishidi Lensimbi Incazelo
Landa ishadi losayizi ogcwele
Isixazululo sokuvimbela ukugqwala kwenqwaba yensimbi yohlobo lwe-Z
AseMelika: HDG (ASTM A123, ubukhulu be-zinc coating ≥85μm) + i-3PE coating ongayikhetha, ebhalwe ukuthi "Ihambisana ne-RoHS enobungani nemvelo".
INingizimu-mpumalanga ye-Asia: I-hot-dip galvanizing (ungqimba lwe-zinc >100μm) ehlanganiswe ne-epoxy coating coating tar inokusebenza okungcono kokugqwala, ukwehluleka kokuhlolwa kwe-salt spray bekulokhu kungu-0 emahoreni angu-5,000, kuyindlela engcono kakhulu yokusebenzisa umoya wasolwandle oshisayo.
Ukukhiya Kwenqwaba Yeshidi Lensimbi Yohlobo lwe-Z
Umklamo: Imininingwane yokuxhumeka kohlobo lwe-z, ukuvuleka kwe-≤1×10⁻⁷cm/s.
IMelika: Ihambisana nezinhlinzeko ze-ASTM D5887, indlela ejwayelekile yokuhlola ukungena kwamanzi ngesisekelo kanye nezindonga zokusekela.
INingizimu-mpumalanga ye-Asia: Ukumelana okuphezulu kwamanzi aphezulu emhlabathini kanye nokugeleza kwamanzi ezikhungweni ezishisayo nezinezimvula.
Inqubo Yokukhiqiza Inqwaba Yeshidi Lensimbi Yohlobo lwe-Z
Ukukhethwa Kwensimbi:
Khetha izinga lekhwalithi yensimbi yesakhiwo ngokusekelwe kwezinye izidingo zempahla yemishini.

8. Ukuqinisekiswa kwesisindo kanye nobuningi- Qinisekisa isisindo sangempela, inani lephakheji, kanye nemininingwane ye-oda ngaphambi kokuthunyelwa.
9. I-MTC kanye Nokulandelela- NikezaIzitifiketi Zokuhlolwa Kwesigayo (i-MTC)ngezinombolo zokushisa kanye nemiphumela yokuhlolwa kokulandelela izinto.
10. Ukuhlolwa Kwabanye Abantu– Ukuhlolwa okuzimele kwe-SGS, BV, CCIC, TUV, noma okunye kungahlelwa ngokuya ngezidingo zamakhasimende.
Isicelo Esiyinhloko Senqwaba Yeshidi Lensimbi Yohlobo lwe-Z
Ubunjiniyela bePort kanye neMarine:Kusebenza ezindongeni ze-quay, ezindaweni zokungena, ezindongeni zokugcina amanzi olwandle, ezindongeni zolwandle, nasezisekelweni zomsele.
Ukuvikelwa Kwezikhukhula:Kusebenza ekulawuleni izikhukhula, ekuvikeleni usebe lomfula, ekuvikeleni ugu kanye nasezindaweni zokugcina amanzi.
Imigodi Yesisekelo Esijulile:Izinqwaba zeshidi ze-Z zilungele ukugcina umhlaba ukuze kumbiwe inhlabathi ejulile, kwakhiwe ngaphansi komhlaba.
AmaCofferdams:Isetshenziselwa ukwakha izindawo zokusebenza zesikhashana ezivalekile emifuleni, ezindongeni zechweba lolwandle nasezindaweni zasolwandle.
Amaphrojekthi eBhuloho kanye nengqalasizinda:Ilungele imigudu esondela ebhulohweni, izindonga zemigudu, umsebenzi womgwaqo, umsebenzi wesitimela kanye nomsebenzi womphakathi ojwayelekile.
Izindonga Zokugcina Ezihlala Njalo:Izinqwaba ze-Z ezinamandla aphezulu zingasetshenziswa nasezindongeni zokugcina unomphela, uma zakhiwe ngokuvikelwa kokugqwala okufanele kanye nokucabangela isikhathi senkonzo.
Kungani Ukhethe Iqembu Lensimbi Yasebukhosini?
1. Izindinganiso Zomhlaba Wonke– Imikhiqizo inganikezwa ngokuhambisana ne-EN 10248, i-ASTM A328 noma i-JIS A5528 njengemfuneko ethile yephrojekthi.
2. Ukuxhumanisa Okusebenzayo- Izingidi ezigoqekile ezishisayo zigoqekile kahle ukuqinisekisa ukuthi udonga luhlala luqinile futhi lufana nge-engeli yokuma efanayo.
3. Izinhlobonhlobo zamaphrofayili nobude- Amaphrofayili e-Z adumile afika nobude obujwayelekile noma obuhlelwe ngokwezifiso, ukuze avumelane nezidingo ezahlukene zobunjiniyela.
4. Ukulawula Ikhwalithi Okuqinile— Ukwakheka kwamakhemikhali, izakhiwo zemishini, ubukhulu, ukuqondile, ukuqeda ubuso kanye ne-geometry yokuxhumanisa kuyahlolwa.
5. Imibhalo Egcwele- Kufaka phakathi i-MTC, imibiko yokuhlola enobukhulu futhi ingahlolwa ngumuntu wesithathu.
Ukupakisha Nokuthumela
Ukupakisha:
Yonke imikhiqizo yenqwaba yensimbi ipakishwe kahle ngemicu yensimbi enamandla aphezulu, futhi iqiniswa ngamabheringi okhuni noma ozimele bensimbi ukuvimbela ukuphambuka ngesikhathi sokuthuthwa. Uma kudingeka, kungasetshenziswa uwoyela wokuvimbela ukugqwala, noma isivikelo esingangeni manzi, esingavikelwa ekugqwaleni isikhathi eside.
Izinketho Zokuthutha:
Kuye ngokuthi iphrojekthi izoba kuphi kanye nesidingo sayo, sinikeza isevisi yokuthutha ngomkhumbi, njll. Siqinisekisa ukuphepha kokuthunyelwa ngokusebenzisa izitsha, izithwali ezinkulu noma ama-flat racks.
Sisizwa izinhlelo zokupakisha zobungcweti kanye nokusekelwa kwempahla okuthembekile emhlabeni wonke, asilokothi sehluleke ukuletha imikhiqizo yensimbi ngendlela ephephile, esheshayo, nebamba kahle.
