I-N-Methylpyrrolidone (NMP): IMiqathango eQinisayo yokusiNgqongileyo Ikhuthaza i-R&D yeeNdlela ezizezinye kunye nokuVeliswa koTshintsho lwe-NMP ngokwawo kuMacandelo akwiSiphelo esiPhezulu

I. IiNdlela eziPhambili zoShishino: eziqhutywa nguMimiselo kunye neNguqu kwiMarike

Okwangoku, eyona ndlela ifikelela kude echaphazela ishishini le-NMP ivela kulawulo lolawulo lwehlabathi.

1. Izithintelo phantsi kwe-EU REACH Regulation

I-NMP ibandakanywe ngokusesikweni kuLuhlu lwaBagqatswa beZinto eziNxinzelela kakhulu (SVHC) phantsi koMgaqo we-REACH.

Ukusukela ngoMeyi ka-2020, i-EU ithintele unikezelo kuluntu lwemixube equlathe i-NMP kugxininiso lwe-≥0.3% kwiiarhente zokucoca isinyithi kunye nemixube yokwaleka kusetyenziso lweshishini kunye nobuchwephesha.

Lo mmiselo usekelwe ikakhulu kwiinkxalabo malunga netyhefu yokuzala ye-NMP, ejonge ukukhusela impilo yabathengi kunye nabasebenzi.

2. Uvavanyo loMngcipheko yi-Arhente yoKhuseleko lweNdalo yase-US (EPA)

I-US EPA ikwaqhuba uhlolo olubanzi lomngcipheko kwi-NMP, kwaye kunokwenzeka kakhulu ukuba izithintelo ezingqongqo ekusebenziseni kwayo kunye nokukhutshwayo kuya kwaziswa kwixesha elizayo.

Uhlalutyo lwempembelelo

Le mimiselo ikhokelele ngokuthe ngqo ekwehleni kancinci kwemfuno yentengiso ye-NMP kumacandelo emveli okunyibilikisa (njengepeyinti, ii-coatings, kunye nokucoca isinyithi), ukunyanzela abavelisi kunye nabasebenzisi abasezantsi ukuba bafune utshintsho.

II. Imida yeTekhnoloji kunye nezicelo ezisakhulayo

Ngaphandle kwezithintelo kumacandelo emveli, i-NMP ifumene abaqhubi abatsha bokukhula kwezinye iindawo zobugcisa obuphezulu ngenxa yeempawu zayo ezizodwa kunye neekhemikhali.

1. I-R&D yezinye izinto (Okwangoku olona lwalathiso lusebenzayo loPhando)

Ukujongana nemiceli mngeni yolawulo, uphuhliso lweendlela ezinokuthi zibe nobuhlobo kokusingqongileyo kwi-NMP ngoku kujongwe kwiinzame zeR&D. Imikhomba-ndlela ephambili ibandakanya:

I-N-Ethylpyrrolidone (NEP): Kuyafaneleka ukuqaphela ukuba i-NEP nayo ijongene nokuhlolwa okungqongqo kwendalo kwaye ayisosisombululo sexesha elide.

I-Dimethyl Sulfoxide (DMSO): Ifundwa njengenye i-solvent kwezinye i-pharmaceutical synthesis kunye ne-lithium-ion battery sector.

Izinyibilikisi ezitsha zohlaza: Kubandakanya i-cyclic carbonates (umz., ipropylene carbonate) kunye nezinyibilikisi ezisekwe kwibhayoloji (umz., i-lactate ephuma kumbona). Ezi zinyibilikisi zinetyhefu esezantsi kwaye ziyakwazi ukubola, nto leyo ezenza zibe ngumkhombandlela wophuhliso oluphambili kwixesha elizayo.

2. Ukungabinandawo kwi-High-Tech Manufacturing

Kwimimandla ethile ephezulu, i-NMP ihleli kunzima ukutshintshwa ngokupheleleyo okwangoku ngenxa yokusebenza kwayo okugqwesileyo:

Iibhetri zeLithium-Ion: Le yeyona ndawo ibalulekileyo nekhula ngokuqhubekayo kwisicelo se-NMP. I-NMP sisinyibilikisi esiphambili sokulungiselela i-slurry ye-lithium-ion battery electrode (ingakumbi i-cathodes). Inokuthi inyibilikise izibophelelo ze-PVDF kwaye ibe ne-dispersibility efanelekileyo, ebalulekileyo ekwenzeni i-electrode ezinzileyo kunye neengubo ezifanayo. Ngokunyuka kwehlabathi kushishino lwamandla amatsha, imfuno ye-NMP yococeko oluphezulu kulo mmandla ihlala yomelele.

IiSemiconductors kunye neePaneli zokuBonisa:Kwimveliso ye-semiconductor kunye ne-LCD / i-OLED yepaneli yokubonisa i-panel, i-NMP isetyenziswe njenge-arhente yokucoca ngokuchanekileyo ukususa i-photoresist kunye nokucoca amacandelo achanekileyo. Ukucoceka kwayo okuphezulu kunye nokukwazi ukucoca ngokufanelekileyo kwenza kube nzima okwethutyana ukutshintshwa.

Iipolymers kunye neePlastiki zobuNjineli eziPhezulu:I-NMP yi-solvent ebalulekileyo yokuvelisa iiplastiki zobunjineli eziphezulu zokusebenza ezifana ne-polyimide (PI) kunye ne-polyetheretherketone (PEEK). Ezi zixhobo zisetyenziswa ngokubanzi kwiindawo ezinqamlekileyo ezifana ne-aerospace kunye nezixhobo zombane.

Ukuqukumbela

Ikamva le-NMP lilele “ekuxhobiseni ngamandla nasekuthinteleni ubuthathaka”. Ngakolunye uhlangothi, ixabiso layo elikhethekileyo kwiinkalo zobugcisa obuphezulu liya kuqhubeka nokuxhasa imfuno yemarike kuyo; kwelinye icala, ishishini lilonke kufuneka lamkele utshintsho, likhawulezise iR&D kunye nokukhuthaza ezinye izinyibilikisi ezikhuselekileyo nezinobuhlobo nokusingqongileyo, ukuze kuphendulwe kwindlela engenakuguqulwa yemithetho yokusingqongileyo.
