Propylene Oxide(Po) yog cov ntaub ntawv uas tseem ceeb heev hauv kev tsim cov tshuaj sib txuas. Nws cov kev siv ntau yam suav nrog kev tsim cov polyurethane, polyether, thiab lwm yam khoom lag luam polymer. Nrog rau kev thov kom muaj kev tsim kho rau cov khoom lag luam po ua vaj tse nyob rau ntau yam kev lag luam hauv ntau yam kev lag luam hauv ntau yam kev ua lag luam PO yuav tsum muaj kev loj hlob tseem ceeb hauv lub xyoo tom ntej.

Cov tsav tsheb ntawm kev ua lag luam loj hlob

Qhov kev thov rau PO yog feem ntau yog tsav los ntawm kev ua haujlwm tsim kho thiab tsheb lag luam. Cov kev tsim kho tshiab sai sai, tshwj xeeb tshaj plaws hauv kev tsim nyiaj loj, tau ua rau kev nce qib hauv kev thov kev ua tau zoo thiab raug nqi-cov nqi rwb thaiv tsev. Po-based polyurethane foams tau siv dav hauv kev tsim kho kev tsim kho rau lawv cov rwb thaiv tsev zoo thiab hluav taws kub tiv thaiv cov khoom.

Ntxiv mus, kev lag luam automotive kuj tau ua tus neeg tsav tsheb tseem ceeb ntawm PO kev ua lag luam. Cov khoom siv ntau lawm xav tau plethora ntawm cov khoom uas tuaj yeem tiv taus ntau qhov kub thiab tshuab kev ntxhov siab. Po-based polymers ua tau raws li cov tseev kom muaj thiab muaj kev siv ntau yam hauv kev tsim cov khoom lag luam ntawm cov khoom siv tsheb.

Kev nyuaj rau kev ua lag luam kev loj hlob

Dua li ntawm ntau ntau txoj kev loj hlob, kev ua lag luam ntsib ntau yam kev cov nyom. Ib qho ntawm thawj txoj kev nyuaj yog qhov tsis muaj suab nrov hauv cov khoom siv raw khoom. Tus nqi ntawm cov khoom siv raw xws li propylene thiab oxygen, uas yog qhov tseem ceeb rau PO ntau lawm, yog qhov ua kom tsis muaj peev xwm ua tau cov nqi ntau lawm. Qhov no tuaj yeem cuam tshuam cov peev txheej ntawm PO cov tuam txhab tsim khoom thiab cov peev xwm cuam tshuam rau lawv lub peev xwm los ua tau raws li kev cog lus.

Lwm qhov kev sib tw yog txoj kev cai tswj hwm ib puag ncig uas tau raug tsim tawm ntawm kev lag luam tshuaj lom neeg. Cov khoom siv ntau lawm tsim cov phom sij khib nyiab thiab tsev cog khoom pa tawm, uas tau coj mus rau kev tawm tswv yim thiab nplua los ntawm cov cai tswj hwm. Ua raws li cov cai no, po cov tuam txhab yuav tsum tau nqis peev hauv cov tshuaj khib nyiab kim thiab Emission tswj thev naus laus zis, uas tuaj yeem ua rau lawv cov nqi ntau lawm.

Cov Tsam Thawj Rau Kev Lag Luam Kev Loj Hlob

Dua li ntawm cov kev cov nyom, muaj ntau txoj hauv kev rau kev loj hlob ntawm PO kev ua lag luam. Ib lub sijhawm zoo li no yog qhov xav tau nce ntxiv rau cov ntaub ntawv rwb thaiv tsev hauv kev tsim kho. Raws li cov chaw ua haujlwm ua haujlwm nthuav dav hauv kev tshaj tawm kev lag luam, qhov kev thov rau cov khoom siv rwb thaiv tsev siab uas yuav sawv. Po-based polyurethane ua npuas ncauj muab cov khoom ntiag tug uas ua rau lawv haum rau ntau yam ntawm cov ntawv thov rwb thaiv tsev.

Lwm lub sijhawm nyob rau hauv kev tsim kho tsheb kho tsheb sai sai. Nrog kev ua kom pom tseeb ntawm kev ua kom muaj zog thiab roj kev ua tau zoo, muaj cov khoom siv zuj zus tuaj yeem tiv thaiv kom muaj qhov kub thiab txias thiab tshuab kev ntxhov siab. PO-rased polymers tau raws li cov tseev kom muaj thiab tuaj yeem hloov cov ntaub ntawv ib txwm xws li iav thiab hlau hauv tsheb raug.

Kev ua lag luam ua lag luam Propylene oxide yog qhov zoo, uas tau tsav los ntawm kev ua haujlwm tsim kho thiab tsheb lag luam. Txawm li cas los xij, kev tsis sib xws nyob rau hauv raw cov ntaub ntawv cov nqi thiab cov kev cai tswj ib puag ncig ib puag ncig pose muaj kev nyuaj siab ua lag luam kev loj hlob. Txhawm rau siv rau cov cib fim, po cov tuam txhab yuav tsum tau nyob deb ntawm kev tshawb fawb thiab kev tsim kho kev tsim kho kom ntseeg tau tias muaj txiaj ntsig zoo thiab ib puag ncig kev phooj ywg.
