Iinkqubo zokuRisayikilisha ze-NMP: Utshintsho olugcina iindleko kwiMveliso yeebhetri zeLithium

——Indlela uPengjin anceda ngayo abavelisi bebhetri ukuba bafikelele kwizinga lokuphucula iindleko ngama-99% kunye nokunciphisa iindleko zokuthenga ngama-99% ngokusebenzisa ukubuyiswa kwe-NMP okusebenzayo

Kwinkqubo enzima yokwenziwa kweebhetri ze-lithium, i-N-methyl-2-pyrrolidone (NMP) idlala indima ebalulekileyo ekulungiseleleni i-cathode slurry. Njengesinyibilikisi esibalulekileyo esisetyenziswa kwimveliso ye-electrode, i-NMP ichaphazela ngokuthe ngqo ukuhambelana kwe-slurry, umgangatho wokugquma, kunye nokusebenza ngokubanzi kweemveliso zebhetri ye-lithium. Nangona kunjalo, ngenxa yeendleko zayo eziphezulu kunye nomthamo omkhulu wokusetyenziswa, i-NMP ixesha elide ihlala ingumthwalo omkhulu wemali kubavelisi beebhetri abafuna zombini ukusebenza kakuhle kwemveliso kunye nolawulo lweendleko.

Ukujongana nalo mceli mngeni, iPengjin Intelligent Equipment Co., Ltd. iphuhlise inkqubo yokuphinda isetyenziswe ye-NMP esebenza kakuhle kakhulu eyenzelwe ngokukodwa imigca yokuvelisa ibhetri ye-lithium. Isisombululo sethu sinikeza izinga lokubuyisela eliphambili kushishino ukuya kuthi ga kwi-99%, sinceda abavelisi baguqule isinyibilikisi esilahliweyo sibe sisixhobo esinokuphinda sisetyenziswe. Ngokusekelwe kwisicelo sokwenyani seprojekthi esine-120,000 m³/h air volume coater, le nkqubo inako ukubuyisa i-524.7 kg ye-NMP ngeyure, i-12,592.8 kg ngosuku, kunye ne-3,777,840 kg ngonyaka, ebalwa ngokweentsuku ezingama-300 zokusebenza. Ngexabiso lemarike le-¥8.5 ngekg ye-NMP ecocekileyo kakhulu, oku kubonisa ukonga konyaka kwe-¥32,111,640. Ngokwendlela esebenzayo, oku kuvumela izinga lokuphucula iindleko ze-99% kwiindleko ezinxulumene ne-NMP kunye nokunciphisa kwe-99% kwiindleko zokuthenga kubavelisi abaxhomekeke kakhulu kwi-NMP kwimveliso ye-cathode slurry.

Okwenza inkqubo yokuphinda usebenzise i-NMP kaPengjin ibonakale ikhethekile kuyilo lwayo lwenkqubo oluyilwe kakuhle kunye nokuzivumelanisa nezimo zokwenyani zemveliso. Siphuhlise iindlela ezine ezikhethekileyo zokubuyisela, kubandakanya unyango lokukhupha umphunga, ukubuyisela ubushushu obumdaka, ukufuma, ukubuyisela umoya nge-95%, kunye nonyango lwe-tower okanye i-rotor kwigesi eseleyo. Umsebenzi ngamnye wenziwa ngononophelo ukuze kuphuculwe ukusebenza kakuhle kokubuyisela i-solvent ngelixa kuhlangatyezwana neemfuno zokukhupha ukungcola kokusingqongileyo. Kwangaxeshanye, i-NMP ephinda isetyenziswe igcina ubunyulu obufunekayo bokusetyenziswa kwakhona kwimveliso yebhetri, ivumela ukuhlanganiswa kwakhona okungenamthungo kwiinkqubo zokulungiselela i-cathode slurry ezikhoyo.

Kubavelisi beebhetri ze-lithium, ixabiso lokuphinda kusetyenziswe i-NMP lidlula nje ukunciphisa iindleko zodwa. Likwaxhasa imveliso ezinzileyo, liphucula ukusetyenziswa kwezixhobo, linciphisa inkunkuma ye-solvent, kwaye liqinisa ukuthobela okusingqongileyo. Ngokudibanisa ixabiso lezoqoqosho kunye nokuthembeka kobuchwephesha, inkqubo yokuphinda kusetyenziswe i-NMP kaPengjin ibe sisisombululo esicwangcisiweyo kwiinkampani ezifuna ukuphucula ukhuphiswano kushishino lokuvelisa iibhetri olutshintsha ngokukhawuleza. Kumashishini ajonge ukuphucula ulawulo lwe-solvent kunye nokunciphisa iindleko zokusebenza, inkqubo yokubuyisela i-NMP ephucukileyo ayisanyanzelekanga—yinxalenye ebalulekileyo yemveliso yebhetri ye-lithium yanamhlanje.
