Polyurethane yog ib qho ntawm cov khoom siv yas siv thoob ntiaj teb, tab sis nws feem ntau tsis saib xyuas hauv peb lub neej txhua hnub. Txawm li cas los xij, txawm tias koj nyob hauv tsev, tom haujlwm lossis hauv koj lub tsheb, nws feem ntau tsis nyob deb, nrog rau kev siv kawg xws li lub txaj thiab rooj tog zaum rau lub tsev rwb thaiv tsev, qhov chaw tsheb thiab cov khau khau.

Tab sis raws li nrog rau lwm yam plastics uas mus unrecycled loj, kev siv davpolyurethanetab tom tsim kev txhawj xeeb txog nws qhov kev cuam tshuam ib puag ncig. Txhawm rau kom nkag siab zoo dua cov hauv kev rau kev rov qab los ntawm polyurethane rau kev rov ua dua tshiab thiab hloov cov tshuaj siv hauv nws cov khoom siv nrog lwm cov nroj tsuag, cov kws tshawb fawb los ntawm US Department of Energy's (DOE) Argonne National Laboratory, Northwestern University thiab Dow Chemical Company tau koom ua ke los ua. Thawj qhov kev ntsuam xyuas ntawm "Cov Khoom Siv Hluav Taws Xob ntawm Polyurethane hauv Tebchaws Meskas." Txoj kev tshawb no tau luam tawm nyob rau hauv phau ntawv journal tsis ntev los noEnvironmental Science & Technology.

"Lub hom phiaj yog kom nkag siab tias yuav ua li cas linear piv rau lub voj voog yog peb siv polyurethanes hauv Tebchaws Meskas," piav qhia tus kws sau ntawv Jennifer Dunn, uas yog tus thawj coj ntawm Northwestern's Center for Engineering Sustainability thiab Resilience thiab tus tswv cuab ntawm Txoj Haujlwm ntawm Plastics. , Ecosystems thiab Public Health ntawm lub koom haum rau Sustainability thiab Zog ntawm Northwestern (ISEN). "Peb kuj xav pom seb puas muaj cov hauv kev los txhim kho kev ncig thiab nce bio-based cov ntsiab lus ntawm polyurethanes."

Ib txoj kev lag luam tawm yog ib qho uas cov khoom siv raw siv los ua cov khoom thiab tom qab ntawd feem ntau raug pov tseg thaum kawg ntawm lawv lub neej. Hauv kev lag luam ncig, cov khoom qub qub tau rov qab siv dua. Qhov no txwv qhov yuav tsum tau rho tawm cov peev txheej ntuj ntxiv, xws li cov pob txha pob txha, thaum txo cov pov tseg xa mus rau qhov chaw pov tseg.

Dunn, uas tseem yog tus kws tshaj lij ntawm kev tsim tshuaj lom neeg thiab tshuaj lom neeg ntawm Northwestern's McCormick Tsev Kawm Ntawv ntawm Engineering, tau hais tias thaum cov kws tshawb fawb xav pom cov txheej txheem loj tshaj plaws rau polyurethanes, "pom nws los ntawm cov ntaub ntawv ntws, los ntawm cov ntaub ntawv pib mus txog thaum kawg. ntawm lub neej, nws tsuas yog blatantly linear. "

Raws li tus kws sau ntawv Troy Hawkins, uas yog tus thawj coj ntawm Pab Pawg Roj thiab Khoom Siv hauv Argonne's Systems Assessment Center, txoj kev tshawb fawb tau qhia txog ntau qhov nyuaj uas cuam tshuam txog yuav ua li cas thiab thaum twg polyurethanes tuaj yeem rov qab tau thiab siv dua.

Tab sis raws li nrog rau lwm yam plastics uas mus unrecycled loj, kev siv davpolyurethanetab tom tsim kev txhawj xeeb txog nws qhov kev cuam tshuam ib puag ncig. Txhawm rau kom nkag siab zoo dua cov hauv kev rau kev rov qab los ntawm polyurethane rau kev rov ua dua tshiab thiab hloov cov tshuaj siv hauv nws cov khoom siv nrog lwm cov nroj tsuag, cov kws tshawb fawb los ntawm US Department of Energy's (DOE) Argonne National Laboratory, Northwestern University thiab Dow Chemical Company tau koom ua ke los ua.
