Dej hiav txwv ua rau rov qab HLon Xov Paj Emody Embodies Kev tswj hwm mus rau cov tub rog khib nyiab, cov khoom siv los ntawm cov muaj ntau haiv neeg ntawm dej hiav txwv. Pov tseg nuv ntses nets-muaj xws li 46% ntawm macro-yas khib nyiab hauv thaj chaw pub zaub mov loj, thiab cov neeg ntaus pob ncaws pob Txhua xyoo ua haujlwm rov ua haujlwm rov muaj kwv yees li 1.58 lab tons ntawm marine-derived nylon, lub ntim sib npaug rau 320,000 cov thawv xa khoom. Qhov no tsis tsuas yog mitigates 8 lab tons ntawm cov dej hiav txwv txhua xyoo tab sis kuj yog tsim los ntawm kev ntsuas thib peb hauv kev sib tw) kev kawm ib ISO 14044.
a. Dej hiav txwv khib nyiab
Cov nkoj tshwj xeeb nruab nrog cov booting floating thiab submersible nets ua haujlwm nyob rau hauv tsim cov nkoj uas tau txais kev pom zoo hauv UNESCO pom zoo cov kev cai tswj kev cai lij choj. Cov ntaub ntawv sau ua ntej pib ntawm-Board, cais cov khoom nylon-based los ntawm polyolefin txheej sib cais (nylon searitwater, polyolefin floats).
b. Cov Khoom Ntse Khoom Txuj Ci
Ntawm thaj av regycling hubs, plaub-theem sorting system ntiav:
- NIR (ze-infrared) spectroscopy rau polymer cim (qhov tseeb 99.6%)
- Eddy tam sim no Separators kom tshem tawm cov hlauic paug
- Kev faib dej cua kom tshem tawm cov tsis muaj cov khib nyiab tsis muaj fibrous
- Kev tuav cov ntaub ntawv zoo rau cov khoom txawv teb chaws txawv teb chaws
c. Tsawg-kub depolymerization
Tus kws ntaus ntawv "hydrolink" cov txheej txheem kawm ua nylon rau:
- Cryogenic crushing ntawm -196 ° C txhawm rau tawg cov qauv fiber ntau
- Alkaline hydrolysis ntawm 235 ° C nrog tswj pH (8.5-9.2) rau unleav amide tsev
- Nqus distillation kom huv caprolactam monomers (purity 99.97%)
- Catalytic hydrogenation kom tshem tawm cov cim xim (YI Performance index <5)
d. Molecular Engineering Spinning
Melt Spinning tshwm sim ntawm 265-270 ° C nrog:
- Nano-zinc oxide additives rau UV kev tiv thaiv (SPF 50+ sib npaug)
- Graphene oxide interlayers kom txhim kho tensile modulus (3.2 GPA)
- BI-ua haujlwm kho cov hloov kho kho kom txhim kho qhov zas xim zes (ΔE <1.5 rau tsaus ntxoov ntxoo)
| Chaw ua uas tsis tau haus | Txoj kev xeem | Rov qab siv nylon | Nkauj xwb nylon |
| Lub zog tensile | ASTM D885 | 5.8-6.3 CN / DTEX | 6.0-6.5 CN / DTEX |
| Elongation thaum so | ISO 527-2 | 28-32% | 30-35% |
| Thermal ruaj khov | Kev tsom xam | 240 ° C (5% phaus poob) | 245 ° C |
| Chlorine tsis kam | ISO 105-E01 | A≤5% Lub zog poob tom qab 200ppm NACL raug | ≤3% poob |
| Microbial degradation | ASTM D6691 | 0.082%% / xyoo nyob rau hauv seawater | 0.007% / xyoo |
a. Kev Kawm Tau Zoo Textiles
Ib Tug Coj Ua Si Sab Nraum Zauv Series Siv 200d rov ua dua Nylon paj hauv Ripstop Fabrics, Ua tiav:
- Kua zog zog: 32 (ASTM D1424)
- Dej Rau Sab Kuj: 20,000 hli (ISO 811)
- Luj Txo Qhov hnyav: 15% vs. Plectional Fabric
b. Marine engineering
Nyob rau hauv ntug dej ntawm ntug dej ua liaj ua teb tshav
- RHUAV LOAD: 220KNT (ISO 1965)
- Qoob qaug zog: 85,000 Tsheb Cycles ntawm 30% ntawm Rhuav Lub Zog
- Tus nqi efficiency: 12% qis dua li cov kev xaiv aramid
c. Vojrcular
Lub European khoom kim heev hom yog "Collection" Nta:
- Knitwear nrog 100% siv cov ntsiab lus nylon
- Dyeing siv cov pigments ntuj (piv txwv li, indigo los ntawm indiglofera tintororia)
- Cov tsoos tsho-rau-tsoos tsho recycling, ua tiav 95% kev rov qab ua ke
Cov ntsiab lus ntau lawm ua rau "5R cov ntsiab cai": tsis kam lees, txo, rov qab siv dua, rov ua dua. Qhov tseem ceeb tshaj tawm suav nrog:
- "1 tuj = 1 Reef" program: cog 10m² ntawm coral reef rau txhua tuj cov xov paj muag
- Blockcegain traceazeLility system (powered by Selgeum) rau cov khoom siv pob tshab
- Kev Tshawb Fawb Kev Koom Tes Nrog MIT ntawm Bio-catalalyzed Depolymerization (Hom Phiaj 2025 Kev Lag Luam)
Txog rau hnub tim, cov teg num muaj:
• tshem tawm 820,000 tons ntawm cov khib nyiab yas
• TXHAWB 542 Nquag Zej Tsoom Txhaum Cai Tswj Xyuas Khib
• Txo cov pa roj carbon procissions los ntawm 1.6 lab tons
Los ntawm 2027, lub tuam txhab npaj ntsuas kom ua tiav 5 lab tons / xyoo, siv cov hlab ntsha Qhov kev cog lus no tau raug lees paub nrog "ntiaj teb kev txhawb nqa thoob ntiaj teb" los ntawm lub ntiaj teb kev sib tham, muab cov xov paj uas yog pob zeb hloov pauv.
