Izinhlelo Zokusebenzisa Kabusha ze-NMP: Ushintsho Lomdlalo Olusindisa Izindleko Zokukhiqiza Amabhethri e-Lithium

——Indlela uPengjin asiza ngayo abakhiqizi bamabhethri ukufeza izinga lokuthuthukisa izindleko elingu-99% kanye nokwehliswa okungu-99% kwezindleko zokuthenga ngokusebenzisa ukubuyiselwa kwe-NMP okuphumelelayo

Enqubweni eyinkimbinkimbi yokukhiqizwa kwamabhethri e-lithium, i-N-methyl-2-pyrrolidone (NMP) idlala indima ebalulekile ekulungiseleleni i-cathode slurry. Njenge-solvent ebalulekile esetshenziswa ekukhiqizweni kwe-electrode, i-NMP ithinta ngqo ukuhambisana kwe-slurry, ikhwalithi yokumboza, kanye nokusebenza okuphelele kwemikhiqizo yebhethri le-lithium. Kodwa-ke, ngenxa yezindleko zayo eziphakeme kanye nomthamo omkhulu wokusetshenziswa, i-NMP ibilokhu ingumthwalo wezezimali obalulekile kubakhiqizi bamabhethri abafuna kokubili ukusebenza kahle kokukhiqiza kanye nokulawula izindleko.

Ukuze kuxazululwe le nselele, i-Pengjin Intelligent Equipment Co., Ltd. ithuthukise uhlelo lokuvuselela i-NMP olusebenza kahle kakhulu olwenzelwe ngqo imigqa yokukhiqiza ibhethri le-lithium. Isixazululo sethu sinikeza izinga lokubuyisa elihamba phambili embonini elifika ku-99%, kusiza abakhiqizi ukuguqula i-solvent elahlekile ibe yimithombo engasetshenziswa kabusha. Ngokusekelwe kuhlelo lokusebenza lwangempela olune-120,000 m³/h air volume coater, uhlelo luyakwazi ukubuyisa ama-524.7 kg e-NMP ngehora, ama-12,592.8 kg ngosuku, kanye nama-3,777,840 kg ngonyaka, kubalwa ngesisekelo sezinsuku zokusebenza ezingama-300. Ngentengo yemakethe engu-¥8.5 nge-kg ye-NMP ehlanzekile kakhulu, lokhu kumelela ukonga konyaka okungu-¥32,111,640. Ngokwesimo esingokoqobo, lokhu kwenza kube nesilinganiso sokuthuthukisa izindleko esingu-99% sezindleko ezihlobene ne-NMP kanye nokunciphisa okungu-99% kwezindleko zokuthenga kwabakhiqizi abathembele kakhulu ku-NMP ekukhiqizweni kwe-cathode slurry.

Okwenza uhlelo lokuvuselela i-NMP lukaPengjin luvelele ukwakheka kwalo kwenqubo okuklanywe kahle kakhulu kanye nokuzivumelanisa nezimo zokukhiqiza zangempela. Sithuthukise izindlela ezine ezikhethekile zokuvuselela, okuhlanganisa ukwelashwa kokukhipha uketshezi, ukubuyisa ukushisa okulahliwe, ukujiya, ukubuyiselwa komoya okungu-95%, kanye nokwelashwa kombhoshongo noma kwe-rotor kwegesi esele. Ukuhamba komsebenzi ngakunye kulungiselelwe ngokucophelela ukuze kukhuliswe ukusebenza kahle kokuvuselela ngenkathi kuhlangatshezwana nezidingo zokukhishwa kwemvelo. Ngesikhathi esifanayo, i-NMP ephinde yasetshenziswa igcina ubumsulwa obudingekayo ukuze kusetshenziswe kabusha ekukhiqizweni kwebhethri, okuvumela ukuhlanganiswa kabusha okungenamthungo ezinqubweni zokulungiselela i-cathode slurry ekhona.

Kubakhiqizi bamabhethri e-lithium, inani lokuvuselelwa kabusha kwe-NMP lidlula ukwehliswa kwezindleko kuphela. Liphinde lisekele ukukhiqizwa okusimeme kakhudlwana, lithuthukisa ukusetshenziswa kwezinsiza, linciphisa imfucuza ye-solvent, futhi liqinisa ukuhambisana nemvelo. Ngokuhlanganisa inani lezomnotho nokuthembeka kobuchwepheshe, uhlelo lokuvuselelwa kabusha lwe-NMP lukaPengjin seluyisisombululo esihlakaniphile sezinkampani ezifuna ukuthuthukisa ukuncintisana embonini yokukhiqiza amabhethri eshintsha ngokushesha. Kumabhizinisi ahlose ukuthuthukisa ukuphathwa kwe-solvent nokunciphisa izindleko zokusebenza, uhlelo lokuvuselela i-NMP oluthuthukisiwe alusekho ukhetho—luyingxenye ebalulekile yokukhiqizwa kwamabhethri e-lithium yesimanje.
