Inkqubela phambili yoPhando lwamva nje lweCarbon Dioxide Polyether Polyols eTshayina

Izazinzulu zaseTshayina zenze impumelelo ebalulekileyo kwicandelo lokusetyenziswa kwekharbon diokside, kwaye uphando lwamva nje lubonisa ukuba iTshayina iphambili kuphando ngecarbon dioxide polyether polyols.

ICarbon dioxide polyether polyols luhlobo olutsha lwemathiriyeli yebhayopolymer enamathemba osetyenziso olubanzi kwimarike, njengezinto zokwakha zokugquma, ugwebu lokomba ioyile, kunye nezixhobo zebhayoloji. Isixhobo sayo esiphambili yi-carbon dioxide, ngokukhetha ukusebenzisa i-carbon dioxide inokunciphisa ngokufanelekileyo ukungcoliseka kwendalo kunye nokusetyenziswa kwamandla efosili.

Kutshanje, iqela lophando elivela kwiSebe Chemistry of Fudan University ngempumelelo polymerized utywala multi-equlethe carbonate iqela kunye carbon dioxide ngokusebenzisa infiltration catalytic reaction technology ngaphandle kokongeza izinzisi zangaphandle, kwaye ulungiselele imathiriyeli yepolymer ephezulu efuna akukho post- unyango. Ngelo xesha, izinto eziphathekayo zinozinzo oluhle lwe-thermal, ukusebenza kokucubungula, kunye neempawu zoomatshini.

Kwelinye icala, iqela elikhokelwa yi-academician u-Jin Furen liqhube ngempumelelo i-ternary copolymerization reaction ye-CO2, i-propylene oxide, kunye ne-polyether polyols ukulungiselela imathiriyeli ephezulu ye-polymer enokusetyenziswa kwizinto zokwakha zokugquma. Iziphumo zophando zicacisa ukuba kunokwenzeka ukudibanisa ngokufanelekileyo ukusetyenziswa kweekhemikhali ze-carbon dioxide kunye neempendulo ze-polymerization.

Ezi ziphumo zophando zibonelela ngemibono emitsha kunye nezalathiso zetekhnoloji yokulungiselela izinto ze-biopolymer e-China. Ukusebenzisa iigesi zenkunkuma yemizi-mveliso ezifana nekhabhon diokside ukunciphisa ukungcoliseka kwendalo kunye nokusetyenziswa kwamandla efosili, kunye nokwenza yonke inkqubo yezinto eziphezulu zepolymer ukusuka kwizinto eziluhlaza ukuya ekulungiseleleni "uhlaza" kukwayindlela yexesha elizayo.

Ukuqukumbela, impumelelo yophando lwaseTshayina kwi-carbon dioxide polyether polyols inika umdla, kwaye uphononongo olongezelelweyo luyafuneka kwixesha elizayo ukwenza olu hlobo lwemathiriyeli ephezulu yepolymer isetyenziswe ngokubanzi kwimveliso kunye nobomi.
