Polyurethane waa mid ka mid ah qalabka caagagga ah ee loogu isticmaalka badan yahay adduunka, laakiin inta badan waa la iska indhatiraa nolol maalmeedkeena.Hase yeeshee haddii aad joogtid guriga, shaqada ama gaarigaaga, inta badan ma foga, iyadoo la isticmaalo dhammaadka caadiga ah ee u dhexeeya joodariyaasha iyo barkinta alaabta guriga ilaa dhismaha dahaarka, qaybaha baabuurta iyo xitaa cirifka kabaha.

Laakin sida balaastikada kale ee inta badan aan dib loo warshadayn, isticmaalka baahsan eepolyurethanewaxay dhalinaysaa walaac ku saabsan saamaynta deegaanka.Si loo fahmo fursadaha dib-u-warshadaynta poliurethane ee dib-u-warshadaynta iyo in lagu beddelo kiimikooyinka loo isticmaalo wax-soo-saarka beddelka dhirta, cilmi-baarayaasha Waaxda Tamarta ee Maraykanka (DOE) Argonne National Laboratory, Jaamacadda Waqooyi-galbeed iyo Shirkadda Kiimikada Dow ayaa si wadajir ah u sameeyay si ay u qabtaan. Qiimaynta koobaad ee dhamaystiran ee "Socdaalka Walxaha ee Polyurethane ee Maraykanka."Daraasada ayaa dhawaan lagu daabacay joornaalkaSayniska Deegaanka & Tignoolajiyada.

"Ujeedadu waxay ahayd in la fahmo sida tooska ah ee ka soo horjeeda sida wareegtu u tahay isticmaalkeena polyurethane ee Maraykanka," ayay sharaxday wada-qoraa Jennifer Dunn, oo ah agaasime ku xigeenka Xarunta Waqooyi-galbeed ee Joogitaanka Injineeriyada iyo Adkeysiga iyo xubin ka mid ah Barnaamijka Caagagga , Nidaamyada Deegaanka iyo Caafimaadka Dadweynaha ee Machadka Joogteynta iyo Tamarta ee Waqooyi-galbeed (ISEN)."Waxaan sidoo kale rabnay inaan aragno haddii ay jiraan fursado lagu wanaajinayo wareegtada oo aan kordhineyno waxyaabaha ku saleysan bio-ku-saleysan ee polyurethane."

Dhaqaalaha tooska ah waa midka alaabta ceeriin loo isticmaalo in lagu sameeyo wax soo saar ka dibna sida caadiga ah la tuuro dhamaadka noloshooda.Dhaqaalaha wareegtada ah, isla agabkaas waa la soo celiya oo dib ayaa loo isticmaalaa.Tani waxay xaddidaysaa baahida loo qabo soo saarista kheyraadka dabiiciga ah ee dheeraadka ah, sida shidaalka fosil, iyadoo la dhimayo xadiga qashinka loo diro meelaha qashinka ah.

Dunn, oo sidoo kale ah borofisar ku-xigeenka injineerinka kiimikada iyo bayoolojiga ee Northwestern's McCormick School of Engineering, ayaa sheegay in iyada oo cilmi-baarayaashu ay filayaan in ay helaan nidaam toos ah oo loogu talagalay polyurethane, "iyaga oo ku arkaya habka socodka qalabka, laga bilaabo alaabta bilawga ah ilaa dhammaadka. nolosha, waxay ahayd kaliya toos toos ah."

Sida laga soo xigtay la-qoraaga Troy Hawkins, oo hogaaminaya Kooxda Fuel and Products ee Xarunta Qiimaynta Nidaamyada Argonne, daraasaddu waxay muujisay tiro kakan oo saameeya sida iyo marka polyurethane dib loo soo kabsado oo dib loo warshadeeyo.
