I. Ngā Auahatanga Matua o te Ahumahi: Ngā Ture e Ārahihia ana me te Huringa o te Mākete
I tēnei wā, ko te ia whānui rawa atu e pā ana ki te umanga NMP e ahu mai ana i te tirotiro ture ā-ao.
1. Ngā here i raro i te Ture REACH a te EU
Kua whakaurua mana te NMP ki roto i te Rārangi Kaitono o ngā Matū Tino Āwangawanga (SVHC) i raro i te Ture REACH.
Mai i te marama o Mei 2020, kua aukatia e te EU te tuku ki te marea o ngā ranunga kei roto ko te NMP i te kukū o te ≥0.3% i roto i ngā kaihoko horoi whakarewa me ngā whakatakotoranga paninga mō ngā whakamahinga ahumahi me ngā whakamahinga ngaio.
Ko te take matua o tēnei ture ko ngā āwangawanga mō te paitini o te NMP ki te whānau uri, me te whāinga kia tiakina te hauora o ngā kaihoko me ngā kaimahi.
2. Aromatawai Mōrearea e te Tari Tiaki Taiao o Amerika (EPA)
Kei te whakahaerehia hoki e te US EPA tētahi aromatawai mōrearea whānui mō te NMP, ā, he tino tūponotanga ka whakaurua he here kaha ake mō tōna whakamahinga me ngā tukunga a meake nei.
Tātari Pānga
Nā ēnei ture i ārahi tika ki te hekenga haere o te hiahia mākete mō te NMP i roto i ngā rāngai whakarewa tuku iho (pēnei i ngā peita, ngā paninga, me te horoi whakarewa), ā, nā tēnei kua akiakihia ngā kaihanga me ngā kaiwhakamahi o muri mai ki te rapu huringa.
II. Ngā Rohe Hangarau me ngā Taupānga Hou
Ahakoa ngā here i roto i ngā rāngai tuku iho, kua kitea e te NMP ētahi atu āhuatanga tipu hou i roto i ētahi mara hangarau teitei nā ōna āhuatanga ā-tinana me ā-matū ahurei.
1. Te R&D o ngā Matū Rerekē (Koinei te Aronga Rangahau Tino Kaha i nāianei)
Hei whakatika i ngā wero ture, ko te whakawhanake i ngā huarahi hei whakakapi i te NMP e pai ana ki te taiao te kaupapa matua o ngā mahi R&D i tēnei wā. Ko ngā huarahi matua ko:
N-Ethylpyrrolidone (NEP): He mea tika kia mōhio kei te aro nui atu hoki te NEP ki te taiao, ā, ehara i te otinga pai mō te wā roa.
Dimethyl Sulfoxide (DMSO): Kei te rangahauhia hei whakarewa rerekē i roto i ētahi rāngai hanga rongoā me te pākahiko lithium-ion.
Ngā Whakarewa Kakariki Hou: Kei roto ko ngā warowaihā hurihuri (hei tauira, te warowaihā propylene) me ngā whakarewa koiora (hei tauira, te lactate i ahu mai i te kānga). He iti ake te paitini o ēnei whakarewa, ā, he pirau-koiora hoki, ka waiho hei huarahi whanaketanga matua mō te heke mai.
2. Te Whakakapinga i roto i te Hanga Hangarau-Tirohia
I ētahi mara papai, he uaua tonu te whakakapi katoa i te NMP i tēnei wā nā tōna mahi tino pai:
Ngā Pūhiko Lithium-IonKoinei te mara tono tino nui, ā, kei te tipu haere tonu mō te NMP. Ko te NMP te whakarewa matua mō te whakarite i te paru mō ngā irahiko pākahiko lithium-ion (ina koa ko ngā cathode). Ka taea e ia te whakarewa i ngā here PVDF, ā, he pai te horapa, he mea nui mō te hanga paninga irahiko pumau me te ōrite. I te pikinga o te ahumahi pūngao hou i te ao katoa, kei te kaha tonu te tono mō te NMP parakore teitei i roto i tēnei mara.
Ngā Ārahi-ā-hiko me ngā Paewhiri Whakaaturanga:I roto i te hanga semiconductor me te hanga papa whakaatu LCD/OLED, ka whakamahia te NMP hei horoi tino tika hei tango i te photoresist me te horoi i ngā wāhanga tino tika. Nā te mea he tino parakore, he pai hoki te horoi, he uaua ki te whakakapi mō tētahi wā poto.
Ngā Pūmua me ngā Kirihou Hangarau Tino Pai:He whakarewa nui te NMP mō te hanga kirihou hangarau mahi-teitei pērā i te polyimide (PI) me te polyetheretherketone (PEEK). E whakamahia whānuitia ana ēnei rauemi i roto i ngā mara matatau pērā i te rererangi me ngā taputapu hiko.
Whakamutunga
Ko te heke mai o te NMP kei roto i te "whakamahi i ngā kaha me te karo i ngā ngoikoretanga". I tētahi taha, ko tōna uara ahurei i roto i ngā mara hangarau teitei ka tautoko tonu i te hiahia o te mākete mōna; i tētahi atu taha, me awhi kaha te umanga katoa i ngā huringa, me tere ake te R&D me te whakatairanga i ngā whakarewa rerekē haumaru ake, pai ake hoki mō te taiao, kia taea ai te whakautu ki te ia o ngā ture taiao e kore e taea te whakakore.
