Ulusi wa nayiloni wogwiritsiridwanso ntchito m'nyanja ukuphatikiza njira yosinthira kasamalidwe ka zinyalala zam'madzi, kupeza zida kuchokera kuzinthu zosiyanasiyana zowononga zam'nyanja. Maukonde osodza otayidwa - okhala ndi 46% ya zinyalala zazikulu za pulasitiki ku Great Pacific Garbage Patch - amapanga chakudya choyambirira, pambali pa zingwe zapamadzi zomwe zidachotsedwa, zovala za nayiloni zomwe zidatumizidwa pambuyo pa ogula (mwachitsanzo, zovala zosiyidwa), ndi nsalu zamakampani. Ntchito zobwezeretsanso pachaka zimatenga pafupifupi matani 1.58 miliyoni a nayiloni yochokera m'madzi, voliyumu yofanana ndi makontena 320,000 otumizira. Izi sizimangochepetsa matani 8 miliyoni a pulasitiki omwe amalowa m'nyanja chaka chilichonse komanso amapanga njira yotsekeka pomwe tani iliyonse ya ulusi wopangidwa imalepheretsa matani 2.1 a mpweya wa CO₂, wotsimikiziridwa ndi maphunziro a chipani chachitatu cha LCA (Life Cycle Assessment) pa ISO 14044.
a. Kusonkhanitsa Zinyalala za Oceanic
Sitima zapadera zokhala ndi ma boom oyandama komanso maukonde ozama m'madzi amagwira ntchito m'malo oyeretsera m'madzi, okhala ndi antchito ophunzitsidwa ndi UNESCO yovomerezedwa ndi zinyalala. Zida zosonkhanitsidwa zimayesedwa koyambirira pa bolodi, kupatula zinthu za nayiloni kuchokera ku mapulasitiki a polyolefin pogwiritsa ntchito kulekanitsa kachulukidwe (nayiloni imamira mu 1.04 g/cm³ madzi amchere, zoyandama za polyolefin).
b. Kusanja Zinthu Mwanzeru
Pazigawo zobwezeretsanso, njira yosankhira magawo anayi imagwiritsa ntchito:
- NIR (Near-Infrared) spectroscopy ya chizindikiritso cha polima (zolondola 99.6%)
- Eddy olekanitsa panopa kuchotsa zoipitsa zitsulo
- Gulu la mpweya kuti muchotse zinyalala zopanda ulusi
- Kuwongolera pamanja kwazinthu zotsalira zakunja
c. Low-Kutentha Depolymerization
Mitu ya "Hydrolink" yovomerezeka idasanja nayiloni kukhala:
- Kuphwanyidwa kwa Cryogenic pa -196 ° C kuti muwononge zida za fiber
- Alkaline hydrolysis pa 235 ° C yokhala ndi pH yoyendetsedwa (8.5-9.2) kuti adule zomangira za amide
- Vacuum distillation kuyeretsa ma monomers a caprolactam (kuyera 99.97%)
- Catalytic hydrogenation kuchotsa trace colorants (YI index <5)
d. Molecular Engineering Spinning
Kusungunula kumapezeka pa 265-270 ° C ndi:
- Zowonjezera za nano-zinc oxide zoteteza UV (SPF 50+ yofanana)
- Ma graphene oxide interlayers kuti apititse patsogolo ma tensile modulus (3.2 GPa)
- Zosintha zogwira ntchito ziwiri kuti zithandizire kuyanjana kwa utoto (ΔE <1.5 pamithunzi yakuda)
| Parameter | Njira Yoyesera | Nayiloni Yobwezerezedwanso | Virgin Nylon |
| Kulimba kwamakokedwe | Chithunzi cha ASTM D885 | 5.8–6.3 cN/dtex | 6.0–6.5 cN/dtex |
| Elongation pa Break | ISO 527-2 | 28-32% | 30-35% |
| Kutentha Kukhazikika | Chithunzi cha TGA | 240 ° C (5% kuwonda) | 245 ° C |
| Kukana kwa Chlorine | Chithunzi cha ISO 105-E01 | ≤5% kutaya mphamvu pambuyo pa 200ppm NaCl | ≤3% kutaya |
| Kuwonongeka kwa Microbial | Chithunzi cha ASTM D6691 | 0.082% / chaka m'madzi a m'nyanja | 0.007% / chaka |
a. Zovala Zapamwamba
Mndandanda wotsogola wamtundu wakunja umagwiritsa ntchito ulusi wa nayiloni wa 200D wokonzedwanso munsalu za ripstop, kukwaniritsa:
- Mphamvu ya misozi: 32N (ASTM D1424)
- Kukana kwapakati pamadzi: 20,000 mm (ISO 811)
- Kuchepetsa kulemera: 15% vs. nsalu wamba
b. Marine Engineering
M'mapulojekiti olima mphepo yam'mphepete mwa nyanja, zingwe za nayiloni za 1000D zobwezerezedwanso zikuwonetsa:
- Kuphwanya katundu: 220kN (ISO 1965)
- Kukana kutopa: 85,000 kuzungulira pa 30% ya mphamvu yosweka
- Kutsika mtengo: 12% kutsika kuposa njira zina za aramid
c. Mafashoni Ozungulira
"Ocean Collection" ya mtundu wapamwamba waku Europe:
- Zovala zokhala ndi nayiloni 100% zobwezerezedwanso
- Kupaka utoto pogwiritsa ntchito utoto wachilengedwe (monga indigo wochokera ku Indigofera tinctoria)
- Mapulogalamu obwezeretsanso zovala kuchokera ku chovala, kukwaniritsa 95% kubwezeretsa zinthu
Maukonde opanga amatsatira "Mfundo za 5R": Kukana, Chepetsa, Gwiritsaninso Ntchito, Bwezeraninso, Bwezerani. Zoyambitsa zazikulu ndi izi:
- Pulogalamu ya “1 Ton = 1 Reef”: Kudzala 10m² wa miyala yamchere yamchere pa toni iliyonse ya ulusi wogulitsidwa
- Blockchain traceability system (yoyendetsedwa ndi Ethereum) pakuwonetsetsa kwapang'onopang'ono
- Kafukufuku wogwirizana ndi MIT pa bio-catalyzed depolymerization (kutsata malonda a 2025)
Mpaka pano, pulogalamuyo ili ndi:
• Anachotsa matani 820,000 a zinyalala zapulasitiki zam'madzi
• Inathandiza madera 542 a m'mphepete mwa nyanja posamalira zinyalala
• Kuchepetsa kuchuluka kwa mpweya wa carbon ndi matani 1.6 miliyoni
Pofika chaka cha 2027, kampaniyo ikufuna kukulitsa ntchito zokonza matani 5 miliyoni pachaka, kugwiritsa ntchito njira zolosera zinyalala zoyendetsedwa ndi AI ndi zombo zotsuka zodzitchinjiriza kuti ziwongolere bwino. Kudzipereka kumeneku kwazindikirika ndi "Global Ocean Award" kuchokera ku World Economic Forum, kuyika ulusi ngati mwala wapangodya wa kusintha kwachuma cha buluu.
