Rov ua dua tus nqi thiab kev nyob ntawm S355J0WP Weathering Steel
1. Recycling
Siab dua:
S355j0wp yog100% rov ua dua tshiabYog tias tsis poob ntawm cov khoom, zoo li txhua tus qauv txheej txheem.
Lub ntiaj teb rov qab ua dua rau cov qauv hlau qauv (suav nrog cov qib cua) tshaj90%, raws li nws yog ib txwm reclaimed los ntawm kev rhuav tshem cov qauv thiab reprocessed rau hauv cov hlau tshiab.
Sib cais sib nqus:
Yooj yim sib cais los ntawm cov khib nyiab ntws tawm ntawm kev sib nqus sorting, txhim kho rov qab ua haujlwm.
2. Kev ua tau zoo
Lub Neej Muaj Kev Pab Ntev:
Ua ib qho kev tiv thaivlub moo plaub(xeb txheej), tshem tawm cov kev xav tau pleev xim thiab txo cov txij nkawm rau 50+ xyoo.
Lowers Letters ib puag ncig ib puag ncig ib puag ncig ib puag ncig ib puag ncig vs. pained carbon hlau (tsawg dua rov qab voj voog, tsis txhob khib nyiab).
Txo cov khoom siv:
Lub zog siab dua li cov hlau me me tso cai rau txheej txheem sib txawv, txuag cov khoom raw.
3. Ib puag ncig cuam tshuam
Kev tsim:
Zoo sib xws bootrint rau cov hlau sib txuas (~ 1.85 tons co₂ ib tev ntawm cov hlau), tab sis tau txais kev pab cuam los ntawm kev thoj thiab rov ua dua tshiab.
Niaj hnub nab hluav taws arc rauv (EAF) tuaj yeem tsim nws siv>90% siv seem, txiav cov pa hluav taws los ntawm ~ 50% vs. cug tawg.
Xaus Lub Neej:
Tsis muaj cov tsho tiv no lom (piv txwv li, pleev xim, zinc) kom tau rov ua dua tshiab.
4. Ntawv pov thawj & cov qauv
AS 15804: Ua raws li EU cov qauv kev txhawb nqa rau cov khoom siv.
Cradle-rau-menyuam txaj: Tsim nyog rau ntawv pov thawj vim yog kaw-lub voj rov ua dua tshiab.
5. Sib Piv rau Lwm Yam
| Khoom | Ua Haujlwm Nqi | Kho | Kev Cuam Tshuam Koom Tes (Lifecycle) |
|---|---|---|---|
| S355j0wp | >90% | Tsis muaj (kev tiv thaiv tus kheej) | Tsawg (ntev lifespan) |
| Xim Turbon Steel | >90% | Siab (rov ua dua) | Siab dua (txij nkawm emissions) |
| Stainless hlau | 80–90% | Tsis muaj | Kev Siab Ntau (Ntau Cov theem) |
Tseem Ceeb Takaways
Kev lag luam ncig: Ze-zoo meej rov ua dua tshiab nrog cov hom phiaj xoom-khib nyiab.
Tsawg txij nkawm: Tshem tawm cov xim pleev xim ntsig txog cov kuab lom thiab khib nyiab.
Cov Khoom Noj Carbon Carbon: Ntev + seem raws kev tsim khoom txo qis cov pa roj teeb.
