Qhov Kev Tshawb Fawb Txog Kev Tshawb Fawb Tseeb ntawm Carbon Dioxide Polyether Polyols hauv Suav teb

Cov kws tshawb fawb suav tau ua qhov tseem ceeb hauv kev siv cov pa roj carbon dioxide, thiab cov kev tshawb fawb tshiab qhia tau hais tias Tuam Tshoj yog nyob rau hauv thawj qhov kev tshawb fawb ntawm carbon dioxide polyether polyols.

Cov pa roj carbon dioxide polyether polyols yog ib yam tshiab ntawm biopolymer cov ntaub ntawv uas muaj cov ntaub ntawv dav dav hauv kev ua lag luam, xws li cov ntaub ntawv rwb thaiv tsev, roj drilling ua npuas ncauj, thiab cov ntaub ntawv biomedical.Nws cov khoom siv tseem ceeb yog carbon dioxide, xaiv siv cov pa roj carbon dioxide tuaj yeem txo qhov muaj kuab paug ib puag ncig thiab siv lub zog fossil.

Tsis ntev los no, ib pab neeg tshawb fawb los ntawm Lub Tsev Haujlwm Saib Xyuas Chemistry ntawm Fudan University tau ua tiav cov dej cawv ntau uas muaj carbonate pawg nrog cov pa roj carbon dioxide los ntawm kev siv cov txheej txheem infiltration catalytic cov tshuaj tiv thaiv yam tsis muaj kev sib ntxiv ntawm cov stabilizers sab nraud, thiab npaj cov khoom siv polymer siab uas yuav tsum tsis muaj tom qab. kev kho mob.Nyob rau tib lub sijhawm, cov khoom siv tau zoo thermal stability, kev ua haujlwm zoo, thiab cov khoom siv kho tshuab.

Ntawm qhov tod tes, pab pawg coj los ntawm tus kws tshaj lij Jin Furen kuj tau ua tiav cov tshuaj tiv thaiv ternary copolymerization ntawm CO2, propylene oxide, thiab polyether polyols los npaj cov khoom siv polymer siab uas tuaj yeem siv rau cov khoom siv rwb thaiv tsev.Cov txiaj ntsig kev tshawb fawb tau qhia meej txog qhov ua tau zoo ntawm kev sib txuas cov tshuaj siv tshuaj carbon dioxide nrog cov tshuaj tiv thaiv polymerization.

Cov txiaj ntsig kev tshawb fawb no muab cov tswv yim tshiab thiab cov lus qhia rau kev npaj cov khoom siv biopolymer hauv Suav teb.Siv cov khoom siv khib nyiab xws li cov pa roj carbon dioxide los txo cov pa phem ib puag ncig thiab cov pob txha siv zog, thiab ua rau tag nrho cov txheej txheem ntawm cov khoom siv polymer siab los ntawm cov khoom siv raw rau kev npaj "ntsuab" kuj yog ib qho kev sib tw yav tom ntej.

Hauv kev xaus, Tuam Tshoj txoj kev tshawb fawb tau ua tiav hauv cov pa roj carbon dioxide polyether polyols yog qhov zoo siab, thiab xav tau kev tshawb nrhiav ntxiv rau yav tom ntej kom pab tau cov khoom siv polymer siab no los siv dav hauv kev tsim khoom thiab lub neej.
