I. Mafambiro Eindasitiri Yepakati: Kutungamirirwa Nemitemo uye Kuchinja Kwemusika
Parizvino, maitiro akanyanya kukanganisa indasitiri yeNMP anobva mukutarisirwa kwemitemo yepasi rose.
1. Zvirambidzo pasi peMutemo weEU REACH
NMP yave kuverengerwa zviri pamutemo muCandidate List of Substances of Very High Concern (SVHC) pasi peREACH Regulation.
Kubva muna Chivabvu 2020, EU yakarambidza kupa kune veruzhinji musanganiswa une NMP nehuwandu hwe ≥0.3% muzvishandiso zvekuchenesa simbi uye zvekuputira zvinoshandiswa mumaindasitiri nehunyanzvi.
Mutemo uyu wakavakirwa zvakanyanya pakunetseka nezve chepfu yekubereka yeNMP, nechinangwa chekuchengetedza hutano hwevatengi nevashandi.
2. Kuongororwa kweNjodzi neUS Environmental Protection Agency (EPA)
US EPA iri kuitawo ongororo yakazara yengozi paNMP, uye zvingangoita kuti mitemo yakaoma pakushandiswa kwayo uye kuburitswa kwemhepo inopinda mumhepo ichaiswa mune ramangwana.
Kuongorora Mhedzisiro
Mitemo iyi yakatungamira zvakananga kudzikira zvishoma nezvishoma kwekuda kweNMP pamusika muzvikamu zvechinyakare zve solvent (zvakadai sependi, machira, uye kuchenesa simbi), zvichimanikidza vagadziri nevashandisi vepasi kuti vatsvage shanduko.
II. Miganhu yeTekinoroji uye Mashandisirwo Ari Kubuda
Pasinei nemirau muzvikamu zvechinyakare, NMP yakawana zvinhu zvitsva zvinosimudzira kukura kwebhizinesi mune mamwe maindasitiri epamusoro-soro nekuda kwehunhu hwayo hwepanyama nemakemikari.
1. R&D yeZvinhu Zvimwe (Parizvino Ndiyo Nzira Yekutsvaga Inonyanya Kushanda)
Kuti tigadzirise matambudziko emutemo, kugadzira dzimwe nzira dzisingakuvadzi nharaunda panzvimbo peNMP ndiyo iri kutariswa pari zvino neR&D. Nzira huru dzinosanganisira:
N-Ethylpyrrolidone (NEP): Zvakakosha kuziva kuti NEP inotarisanawo nekuongororwa kwakasimba kwezvakatipoteredza uye haisi mhinduro yakanaka kwenguva refu.
Dimethyl Sulfoxide (DMSO): Iri kudzidzwa seimwe nzira yekunyungudutsa mune mamwe ma pharmaceutical synthesis uye lithium-ion battery sectors.
Zvinonyungudutsa Zvitsva: Zvinosanganisira cyclic carbonates (semuenzaniso, propylene carbonate) uye zvinonyungudutsa zvine bio (semuenzaniso, lactate inobva muchibage). Zvinonyungudutsa izvi zvine chepfu shoma uye zvinogona kuora, zvichiita kuti zvive gwara guru rekuvandudza ramangwana.
2. Kusatsiviwa muKugadzira Zvinhu zveTekinoroji Yepamusoro
Mune mamwe mabasa epamusoro-soro, NMP ichiri yakaoma kutsiviwa zvachose pari zvino nekuda kwekushanda kwayo kwakanaka:
Mabhatiri eLithium-Ion: Iyi ndiyo nzvimbo inonyanya kukosha uye iri kukura yekushandiswa kweNMP. NMP chinhu chakakosha pakugadzirira slurry yemaelectrode ebhatiri re lithium-ion (kunyanya ma cathode). Inogona kunyungudutsa ma PVDF binders uye ine mukana wakanaka wekupararira, izvo zvakakosha pakugadzira ma electrode coatings akagadzikana uye akafanana. Nekukura kwepasi rose muindasitiri itsva yesimba, kudiwa kweNMP yakachena kwazvo mumunda uyu kuchiri kwakasimba.
MaSemiconductors uye Mapaneru Ekuratidza:Mukugadzira ma semiconductor uye kugadzira LCD/OLED display panel, NMP inoshandiswa senzira yekuchenesa nemazvo kubvisa photoresist uye kuchenesa zvikamu zvemazvo nemazvo. Kuchena kwayo kwakanyanya uye kugona kwayo kuchenesa zvinobudirira zvinoita kuti zviome kwenguva pfupi kutsiviwa.
Mapurasitiki ePolymers neMapurasitiki eUinjiniya Epamusoro-soro:NMP chinhu chakakosha pakugadzira mapurasitiki einjiniya ane simba repamusoro akadai sepolyimide (PI) uye polyetheretherketone (PEEK). Zvinhu izvi zvinoshandiswa zvakanyanya muminda yemazuva ano senge midziyo yemuchadenga nemidziyo yemagetsi.
Mhedziso
Remangwana reNMP riri mu "kushandisa simba rayo uye kudzivirira kusasimba". Kune rumwe rutivi, kukosha kwayo kwakasiyana muminda yetekinoroji yepamusoro kucharamba kuchitsigira kudiwa kwayo mumusika; kune rumwe rutivi, indasitiri yese inofanira kugamuchira shanduko, kukurumidzisa R&D uye kukurudzira zvinonyungudutsa zvakachengeteka uye zvine hushamwari kune zvakatipoteredza, kuitira kuti ipindure kune maitiro asingachinjiki emitemo yezvakatipoteredza.
