N-Methylpyrrolidone (NMP): Amabwiriza akomeye y’ibidukikije atera R&D yuburyo butandukanye no guhanga udushya muri NMP ubwayo mu mirenge yo mu rwego rwo hejuru

I. Ibikorwa Byinganda Inganda: Amabwiriza-Gutwara no Guhindura Isoko

Kugeza ubu, inzira igera kure ku nganda za NMP ituruka ku kugenzura isi yose.

1. Ibibujijwe mu Mabwiriza y’ubumwe bw’ibihugu by’Uburayi

NMP yashyizwe kumugaragaro kurutonde rwabakandida rwibintu bireba cyane (SVHC) hakurikijwe amabwiriza ya REACH.

Kuva muri Gicurasi 2020, Umuryango w'ubumwe bw’ibihugu by’Uburayi wabujije kugemurira abaturage imvange zirimo NMP ku gipimo cya .3 0.3% mu bikoresho byoza ibyuma ndetse no gutwikira ibicuruzwa bikoreshwa mu nganda n’umwuga.

Aya mabwiriza ashingiye ahanini ku mpungenge z’uburozi bw’imyororokere ya NMP, bugamije kurengera ubuzima bw’abaguzi n’abakozi.

2. Isuzuma ry’ingaruka n’ikigo cyo muri Amerika gishinzwe kurengera ibidukikije (EPA)

EPA yo muri Amerika nayo irimo gukora isuzuma ryuzuye ry’ingaruka kuri NMP, kandi birashoboka cyane ko hazashyirwaho ingamba zikomeye ku mikoreshereze y’imyuka n’ibyuka bihumanya ikirere.

Isesengura ry'ingaruka

Aya mabwiriza yatumye mu buryo butaziguye igabanuka ry’isoko rya NMP mu nzego gakondo zishyirwa mu bikorwa (nk'irangi, impuzu, hamwe no gusukura ibyuma), bituma abahinguzi n’abakoresha hasi bashaka impinduka.

II. Imipaka yikoranabuhanga hamwe nibisabwa byavutse

Nubwo hari imbogamizi mu nzego gakondo, NMP yabonye imbaraga zo gukura mu bice bimwe na bimwe by’ikoranabuhanga rikomeye bitewe n’imiterere yihariye y’umubiri n’imiti.

1. R&D yubundi buryo (Kugeza ubu Icyerekezo Cyubushakashatsi Cyane)

Kugira ngo ikibazo gikemuke gikemuke, iterambere ryibidukikije byangiza ibidukikije kuri NMP kuri ubu nibyo byibandwaho mu bikorwa bya R&D. Icyerekezo nyamukuru kirimo:

N-Ethylpyrrolidone (NEP): Birakwiye ko tumenya ko NEP nayo igenzurwa cyane n’ibidukikije kandi ntabwo ari igisubizo cyiza kirambye.

Dimethyl Sulfoxide (DMSO): Irimo kwigwa nkubundi buryo bwo gukemura ibibazo bimwe na bimwe bya synthesis ya farumasi hamwe na batiri ya lithium-ion.

Icyatsi gishya kibisi: Harimo karubone ya cyclicale (urugero, karubone ya propylene) hamwe na bio ishingiye kumashanyarazi (urugero, lactate ikomoka kubigori). Iyi mashanyarazi ifite uburozi buke kandi irashobora kubangikanywa, bigatuma iba icyerekezo cyingenzi cyiterambere ryigihe kizaza.

2. Gusimburwa mu buhanga buhanitse

Mubice bimwe-byo murwego rwohejuru, NMP ikomeje kugorana gusimburwa rwose muri iki gihe kubera imikorere yayo myiza:

Batteri ya Litiyumu-Ion: Nibyingenzi kandi bikomeza gukura murwego rwo gusaba kuri NMP. NMP nigisubizo cyingenzi mugutegura amashanyarazi ya electrode ya lithium-ion (cyane cyane cathodes). Irashobora gusenya neza imigozi ya PVDF kandi ifite itandukaniro ryiza, ningirakamaro mugukora amashanyarazi ahamye kandi amwe. Hamwe n’iterambere ry’isi mu nganda nshya z’ingufu, icyifuzo cya NMP gifite isuku nyinshi muri uru rwego gikomeje gukomera.

Semiconductor hamwe na Panel yerekana:Mubikorwa bya semiconductor hamwe na LCD / OLED yerekana ibyerekanwe, NMP ikoreshwa nkibikoresho bisukura neza kugirango ikureho fotora kandi isukuye neza. Isuku ryayo nubushobozi bwiza bwo gukora isuku bituma bigorana gusimburwa byigihe gito.

Polimeri na Plastike yo mu rwego rwo hejuru:NMP nigisubizo cyingenzi mugukora plastike yubuhanga ikora cyane nka polyimide (PI) na polyetheretherketone (PEEK). Ibi bikoresho bikoreshwa cyane mubice bigezweho nko mu kirere n'ibikoresho bya elegitoroniki.

Umwanzuro

Kazoza ka NMP kari mu "kubyaza umusaruro imbaraga no kwirinda intege nke". Ku ruhande rumwe, agaciro kayo kihariye mu buhanga buhanitse buzakomeza gushyigikira isoko ryacyo; Ku rundi ruhande, inganda zose zigomba kwakira neza impinduka, kwihutisha R&D no guteza imbere ubundi buryo bwangiza kandi bwangiza ibidukikije, kugira ngo hasubizwe inzira idasubirwaho y’amabwiriza y’ibidukikije.
