I. Cov Qauv Tseem Ceeb ntawm Kev Lag Luam: Kev Tswjfwm thiab Kev Hloov Pauv ntawm Kev Ua Lag Luam
Tam sim no, qhov sib txawv tshaj plaws uas cuam tshuam rau kev lag luam NMP yog los ntawm kev saib xyuas kev cai lij choj thoob ntiaj teb.
1. Kev txwv raws li EU REACH Regulation
NMP tau raug suav nrog hauv Daim Ntawv Teev Npe ntawm Cov Tshuaj Uas Muaj Kev Txhawj Xeeb Heev (SVHC) raws li REACH Txoj Cai.
Txij li thaum lub Tsib Hlis 2020, EU tau txwv tsis pub muab cov khoom sib xyaw uas muaj NMP ntawm qhov concentration ntawm ≥0.3% hauv cov neeg sawv cev ntxuav hlau thiab cov tshuaj pleev xim rau kev siv hauv kev lag luam thiab kev tshaj lij.
Txoj cai no feem ntau yog raws li kev txhawj xeeb txog kev lom ntawm NMP, lub hom phiaj yog los tiv thaiv kev noj qab haus huv ntawm cov neeg siv khoom thiab cov neeg ua haujlwm.
2. Kev Ntsuam Xyuas Kev Pheej Hmoo los ntawm Lub Chaw Tiv Thaiv Ib Puag Ncig ntawm Tebchaws Meskas (EPA)
Lub Chaw Tiv Thaiv Ib Puag Ncig Hauv Tebchaws Meskas (US EPA) kuj tseem tab tom ua qhov kev ntsuam xyuas txog kev pheej hmoo ntawm NMP, thiab nws muaj feem ntau tias yuav muaj kev txwv nruj dua rau nws txoj kev siv thiab kev tso pa phem yav tom ntej.
Kev Tshawb Fawb Txog Qhov Cuam Tshuam
Cov kev cai no tau ua rau muaj kev poob qis ntawm kev thov ua lag luam rau NMP hauv cov khoom siv ib txwm muaj (xws li xim, tshuaj pleev xim, thiab kev ntxuav hlau), yuam cov chaw tsim khoom thiab cov neeg siv khoom hauv qab no nrhiav kev hloov pauv.
II. Cov Kev Siv Tshuab thiab Cov Kev Siv Tshiab
Txawm hais tias muaj kev txwv hauv cov lag luam ib txwm muaj, NMP tau pom cov tsav tsheb tshiab rau kev loj hlob hauv qee qhov chaw siv thev naus laus zis siab vim nws cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.
1. Kev Tshawb Fawb thiab Kev Txhim Kho Cov Tshuaj Lwm Yam (Tam sim no yog Kev Tshawb Fawb Tseem Ceeb Tshaj Plaws)
Txhawm rau daws cov teeb meem kev cai lij choj, kev tsim cov kev xaiv uas tsis ua rau ib puag ncig puas tsuaj rau NMP tam sim no yog qhov tseem ceeb ntawm kev siv zog R&D. Cov lus qhia tseem ceeb suav nrog:
N-Ethylpyrrolidone (NEP): Nws tsim nyog sau tseg tias NEP kuj ntsib kev tshuaj xyuas ib puag ncig nruj heev thiab tsis yog qhov kev daws teeb meem zoo tshaj plaws rau lub sijhawm ntev.
Dimethyl Sulfoxide (DMSO): Nws tab tom raug kawm ua lwm txoj hauv kev los ua cov kuab tshuaj hauv qee qhov kev tsim tshuaj thiab cov roj teeb lithium-ion.
Cov Tshuaj Ntsuab Tshiab: Xws li cov cyclic carbonates (piv txwv li, propylene carbonate) thiab cov tshuaj bio-based (piv txwv li, lactate uas tau los ntawm pob kws). Cov tshuaj no muaj cov tshuaj lom tsawg dua thiab lwj tau, ua rau lawv yog qhov tseem ceeb rau kev txhim kho yav tom ntej.
2. Kev Hloov Tsis Tau Hauv Kev Tsim Khoom Siv High-Tech
Hauv qee qhov chaw ua haujlwm siab, NMP tseem nyuaj rau hloov pauv tag nrho tam sim no vim nws ua tau zoo heev:
Cov roj teeb Lithium-IonQhov no yog qhov tseem ceeb tshaj plaws thiab txuas ntxiv loj hlob daim teb thov rau NMP. NMP yog cov kuab tshuaj tseem ceeb rau kev npaj cov slurry rau cov electrodes roj teeb lithium-ion (tshwj xeeb tshaj yog cathodes). Nws tuaj yeem yaj cov PVDF binders thiab muaj kev sib kis zoo, uas yog qhov tseem ceeb rau kev tsim cov txheej electrode ruaj khov thiab sib xws. Nrog rau kev vam meej thoob ntiaj teb hauv kev lag luam hluav taws xob tshiab, qhov kev thov rau NMP siab-purity hauv daim teb no tseem muaj zog.
Cov Khoom Siv Semiconductors thiab Cov Vaj Huam Sib Luag:Hauv kev tsim cov khoom siv semiconductor thiab LCD/OLED zaub vaj huam sib luag, NMP yog siv los ua tus neeg sawv cev ntxuav kom raug kom tshem tawm cov photoresist thiab ntxuav cov khoom ua haujlwm raug. Nws qhov kev ntshiab siab thiab kev ntxuav tau zoo ua rau nws nyuaj rau hloov ib ntus.
Cov Polymers thiab Cov Khoom Siv Engineering Zoo Tshaj Plaws:NMP yog ib qho tshuaj yaj tseem ceeb rau kev tsim cov yas engineering ua tau zoo xws li polyimide (PI) thiab polyetheretherketone (PEEK). Cov ntaub ntawv no siv dav hauv cov teb tshiab xws li aerospace thiab cov khoom siv hluav taws xob.
Xaus lus
Yav tom ntej ntawm NMP yog nyob rau hauv "kev siv zog ntawm lub zog thiab zam kev qaug zog". Ntawm ib sab tes, nws tus nqi tshwj xeeb hauv cov teb high-tech yuav txuas ntxiv txhawb nqa kev thov ntawm kev ua lag luam rau nws; ntawm qhov tod tes, tag nrho kev lag luam yuav tsum nquag txais yuav kev hloov pauv, ua kom nrawm R&D thiab txhawb nqa cov tshuaj yaj uas muaj kev nyab xeeb dua thiab zoo rau ib puag ncig, kom teb rau qhov sib txawv ntawm cov cai ib puag ncig.
