Sharaxaada Alaabta

1. Qeexida Alaabta & Xudunta Deegaanka

Duubka polyester-ka ee dib loo warshadeeyay ee badweynta waxay ka dhigan tahay hal-abuurka cusub ee dunta, oo lagu farsameeyay beddelka qashinka caagagga badda - shabaqyada kalluumaysiga ee inta badan la tuuro, dhalooyinka caagagga ah ee macaamiisha ka dambeeya, iyo baakadaha badda - fiber-waxqabad sare leh iyada oo loo marayo dib-u-warshadaynta jirka iyo tignoolajiyada dib-u-cusboonaynta kiimikada. Tan kasta oo duntan ah oo la soo saaro waxa ay tirtirtaa ku dhawaad 3.2 tan oo CO₂ qiiqa, oo u dhiganta awoodda kala wareejinta kaarboon ee 156 geed oo bislaaday muddo toban sano ah. Tani kaliya kama hadlayso dhibaatada degdega ah ee "wasakhowga cad" ee badaha aafeeya laakiin sidoo kale waxay dib u qeexdaa wareegtada walxaha. Adkeysi jaban oo ah 4.7–5.3 cN/dtex (oo lagu tijaabiyay ASTM D2256) iyo midabaynta midabaynta 92% midabka asalka ah kadib 500 saacadood ee soo-gaadhista UV (ISO 105-B02), waxay ka sarraysaa polyester-ka bikrada labadaba masuuliyada deegaanka iyo cimri dhererka farsamada.

2. Geedi socodka saaxiibtinimada leh ee wareegga-buuxa ah

Marxaladda dib u warshadaynta: Waxaa ku hawlan shaqaale nadiifin badeed oo shahaado haysta, wejiga hore waxa ku jira in la geeyo maraakiibta khaaska ah si ay u ururiyaan caagadaha macro-caagaga ah ee laga soo qaado deegaanka xeebaha iyo badaha furan. Shabaqyada kalluumeysiga ee la tuuray-oo inta badan mas'uul ka ah 46% qashinka caagga badweynta-waxay maraan nidaam saddex-tallaabo ah oo kala soocidda: Kala soocida magnetka si meesha looga saaro jajabyada birta, taangiyada sabbeynta si loo go'doomiyo polymers PET, iyo kala-soocida indhaha si loo baabi'iyo caagadaha midabka leh. Walaxda ayaa markaa si qaylo-dhaan ah loo burburiyaa 3-5 mm granules, taasoo lagu gaadhayo heerka nadiifnimada 99.8%.Marxaladda dib u soo kabashada: Shaqaalaysiinta dariiqyada teknoolajiyada ee laba-geesoodka ah, ama ka saarista heerkulka hooseeya (265-278 ° C oo leh nitrogen inerting si looga hortago xaalufka kulaylka) ama depolymerization kiimikaad ku salaysan glycolysis, granules waxaa loo beddelaa chips PET-cunto ah. Habkani waxa uu luminayaa luminta viscosity 70% marka la barbar dhigo dib u warshadaynta caadiga ah, oo leh wasakhda raad raac (biraha culus <0.005 ppm, VOCs <0.1 mg/kg) oo ay ansixisay GC-MS spectrometry.Marxaladda WareegaIsticmaalka mashiinnada wareegyada hawada-jet-ka casriga ah (ku shaqeeya 4,200-4,800 m/min), chips-yada waxaa lagu sii daayaa iyada oo loo marayo spinnerets oo leh meelo wax laga beddelay si loo abuuro qaab-dhismeedka fiber-ka jasiiradda. Goynta nanoscale Tani waxay kordhisaa bedka dusha gaarka ah 28%, iyada oo kor u qaadeysa xawaaraha wicking min 12 mm/30s to 16 mm/30s (AATCC 97 standard) iyo yaraynta wakhtiga qalajinta 35%. Dhammaan silsiladda wax-soo-saarka ayaa 42% tamar ka yar wax-soo-saarka polyester-ka bikrada ah, oo leh nidaam biyo-xidheen ah oo gaadhaya 97% waxtarka dib-u-warshadaynta.

3. Faa'iidooyinka kala duwan & Codsiyada

Shahaadada deegaanka & cabbirada waxqabadka:

GRS (Heerka Dib-u-warshadaynta Caalamiga ah) waxaa lagu shahaadeeyay 91.5% ka kooban badeed, oo lagu xaqiijiyay falanqaynta isotope carbon

OEKO-TEX Heerka 100 Fasalka I u hoggaansanaanta, xaqiijinaysa maqnaanshaha 194 walxaha xaddidan

Xaaladaha biyaha badda ee la isku ekeeyey (3.5% cusbada, 22°C), xaalufka microbial wuxuu gaaraa 0.132% 6 bilood gudahood, 12 jeer ayuu ka sareeyaa PET-ga caadiga ah (ASTM D6691)

Tilmaamaha Farsamada:

Kala duwanaanshaha diidmada: 15D/12F ilaa 300D/96F, taageeridda dharka beenta ah ee dharka firfircoon iyo dharka warshadaha culus

modules Tensile: 28-32 GPa, hubinta caabbinta abrasion ee xadhkaha badda (ASTM D3884)

Kaniiniga caabbinta: Fasalka 4-5 (ISO 12945-2), oo ka sarreeya 80% dharka dibadda ee caadiga ah

Codsiga deegaanka deegaanka:

Warshadaha dibaddaJaakadda adag ee 3-lakabka ah ee hormuudka ka ah ee la isticmaalayo 100% dun dib loo warshadeeyay ayaa muujinaysa 20,000 mm caabbinta tiirarka biyaha iyo neefsiga 15,000 g/m²/24h, iyadoo hoos u dhigaysa nolosha meertada kaarboonka 63% marka la barbar dhigo moodooyinka polyester-ka ee bikrada ah.

Injineernimada baddaXadhkaha goosashada markabku waxay ka soo miiqayaan dunta dib loo warshadeeyay ee 200D waxay muujinaysaa 98% xoogga jabinta fiilooyinka polyester-ka ee bikrad ah, oo lagu tijaabiyay inay u adkeystaan 50,000 wareegyada cadaadiska xajinta (ISO 1833).

Mashruucyada Dhaqaalaha WareegtadaHindisaha iskaashiga ah ee dib-u-warshadaynta dharka Yurub, dunta waxaa loo isticmaalaa muraayadaha roogagga modular kuwaas oo dib loogu dhejin karo fiilooyinka cusub dhammaadka nolosha, taasoo lagu gaaro heerka dib u warshadaynta 90%.

4. Hababka Horumarineed ee Joogtada ah

Iyada oo qayb ka ah "Heshiiska Caagagga Badweynta", shabakadda wax-soo-saarka ayaa iskaashi la leh 18 hay'adood oo ilaalinta badda ah oo ku kala baahsan 22 waddan, iyaga oo u qoondeynaya 1.5% dakhliga iibka si loo maalgeliyo hawlaha nadiifinta xeebaha. Ilaa hadda, tani waxay awood u siisay dib u soo kabashada 6,240 tan oo qashinka balaastikada badda ah-ku filan in la soo saaro 2.3 milyan mitir toosan oo dun ah oo loogu talagalay noocyada deegaanka miyirka leh. Hal-abuurka dib-u-warshadaynta ka dib macaamiisha ayaa socota, iyada oo warshad tijaabo ah loo qorsheeyay 2024 si loo farsameeyo qashinka isku dhafan ee caagga ah iyada oo la adeegsanayo depolymerization horumarsan, iyada oo ujeeddadeedu tahay in la kordhiyo waxyaabaha dib loo warshadeeyay ilaa 98% iyada oo la gaarayo qiiqa kaarboonka saafiga ah-eber ee 2026. Ballanqaadkan ayaa lagu aqoonsaday "Abaalmarinta Dharka Joogtada ah" ee ka soo baxda warshadaha casriga ah ee warshadaha casriga ah ku model dhaqaalaha buluug.
