N-Methylpyrrolidone (NMP): Amabwiriza akomeye yo kubungabunga ibidukikije atera inkunga ubushakashatsi n'iterambere ry'uburyo bushya bwo gukoresha NMP ubwayo mu nzego zigezweho

I. Inzira z'ingenzi z'inganda: Ishingiye ku mabwiriza n'impinduka ku isoko

Muri iki gihe, isura ikomeye cyane igira ingaruka ku nganda za NMP ikomoka ku kugenzura amategeko mpuzamahanga.

1. Amategeko agenga EU REACH

NMP yashyizwe ku mugaragaro mu rutonde rw'abakandida rw'ibintu bihangayikishije cyane (SVHC) hakurikijwe amabwiriza ya REACH.

Kuva muri Gicurasi 2020, Umuryango w’Ubumwe bw’u Burayi wabujije abaturage gutanga imvange irimo NMP ku kigero cya ≥0.3% mu bikoresho byo gusukura ibyuma n’ibisigazwa byo gusiga kugira ngo bikoreshwe mu nganda no mu by’umwuga.

Iri tegeko rishingiye ahanini ku mpungenge ku bijyanye n'uburozi bw'imyororokere bwa NMP, bugamije kurengera ubuzima bw'abaguzi n'abakozi.

2. Isuzuma ry'ibyago rikorwa n'Ikigo gishinzwe kurengera ibidukikije muri Amerika (EPA)

EPA yo muri Amerika irimo gukora isuzuma ryimbitse ry’ingaruka za NMP, kandi birashoboka cyane ko hazabaho amabwiriza akaze ku ikoreshwa ryayo n’ibyuka bihumanya ikirere mu gihe kizaza.

Isesengura ry'Ingaruka

Aya mabwiriza yatumye isoko ry’ibikenewe bya NMP rigabanuka buhoro buhoro mu buryo busanzwe mu bijyanye n’ibinyabutabire (nk’amarangi, irangi, no gusukura ibyuma), bituma abakora n’abakoresha ibikoresho byo hasi bashaka impinduka.

II. Imbibi z'ikoranabuhanga n'ikoreshwa rizagaragara

Nubwo hari imbogamizi mu nzego gakondo, NMP yabonye ibintu bishya bitera iterambere mu nzego zimwe na zimwe zikoresha ikoranabuhanga rihanitse bitewe n’imiterere yayo yihariye y’umubiri n’imiti.

1. Ubushakashatsi n'Iterambere ry'Ibikoresho Bisimbura Ibindi (Ubu ni bwo buryo bugezweho bwo gukora ubushakashatsi)

Kugira ngo hakemurwe ibibazo bifitanye isano n’amategeko, guteza imbere ubundi buryo butangiza ibidukikije aho gukoresha uburyo bwa NMP muri iki gihe ni cyo cyibandwaho mu bikorwa byo gusesengura no guteza imbere ibidukikije. Ibyerekezo by’ingenzi birimo:

N-Ethylpyrrolidone (NEP): Ni ngombwa kumenya ko NEP ikwiye no gusuzumwa cyane ku bidukikije kandi si igisubizo cyiza cy’igihe kirekire.

Dimethyl Sulfoxide (DMSO): Iri kwigwa nk'umusemburo mu buryo bumwe na bumwe mu buryo bwo gukora imiti no mu bice bimwe na bimwe by'ubuhanga bwa litiyumu-iyoni.

Ibinyabutabire bishya: Harimo karubone zikora ku buryo bw'ikirere (urugero, propylene carbonate) n'ibinyabutabire bishingiye ku binyabuzima (urugero, lactate ikomoka ku bigori). Ibi binyabutabire bifite uburozi buke kandi bishobora kubora, bigatuma biba icyerekezo cy'ingenzi cy'iterambere ry'ejo hazaza.

2. Kudasimburwa mu nganda zikoresha ikoranabuhanga rihanitse

Mu nzego zimwe na zimwe zo mu rwego rwo hejuru, NMP iracyagoranye gusimburwa burundu muri iki gihe bitewe n'imikorere yayo myiza:

Bateri za Lithium-Ion: Iyi ni yo mashini y'ingenzi kandi ikomeza gukura ya NMP. NMP ni igikoresho cy'ingenzi cyo gutegura urusenda rwa electrode za bateri ya lithium-ion (cyane cyane cathode). Ishobora gushonga neza PVDF binders kandi ifite ubushobozi bwo gukwirakwira neza, ibyo bikaba ari ingenzi mu gukora electrode coatings zihamye kandi zihuye. Kubera iterambere ry'isi mu nganda nshya z'ingufu, gukenera NMP ifite isuku nyinshi muri uru rwego biracyakomeye.

Udukoresho twa semiconductors n'udukoresho tw'iyerekana:Mu nganda zikora ibikoresho bya semiconductor no mu gukora LCD/OLED display panel, NMP ikoreshwa nk'icyuma gisukura neza kugira ngo ikureho ibice birwanya ubushyuhe n'ubuziranenge. Isuku yayo ihanitse kandi ikora neza bituma bigorana kuyisimbuza mu gihe gito.

Polymers na Plastiki z'Ubwubatsi Bukomeye:NMP ni umuti w'ingenzi mu gukora pulasitiki zikora neza nka polyimide (PI) na polyetheretherketone (PEEK). Ibi bikoresho bikoreshwa cyane mu nzego zigezweho nko mu kirere no mu bikoresho by'ikoranabuhanga.

Umwanzuro

Ahazaza ha NMP hari mu "gukoresha imbaraga nyinshi no kwirinda intege nke". Ku ruhande rumwe, agaciro kayo kadasanzwe mu ikoranabuhanga rigezweho kazakomeza gushyigikira icyifuzo cy'isoko ryayo; ku rundi ruhande, inganda zose zigomba kwemera impinduka, kwihutisha ubushakashatsi n'iterambere no guteza imbere imiti isukura kandi itekanye kandi idahumanya ibidukikije, kugira ngo ihuze n'amahame agenga ibidukikije adahinduka.
