Isisombululo seZixhobo zokuCoca i-NMP esiSebenzayo: Inkqubo yokuBuyisa eyenziwe ngokwezifiso nguPengjin

Intshayelelo

I-NMP (i-N-Methyl-2-pyrrolidone) sisinyibilikisi esibalulekileyo ekuvelisweni kweebhetri ze-lithium. Nangona kunjalo, iifektri ezininzi zebhetri eziphakathi nezinkulu zikhathazwa lizinga eliphantsi lokubuyisa i-NMP, iindleko eziphezulu zokusebenza, isalathisi sokukhupha esingazinziyo kunye nokusilela rhoqo kwezixhobo. Isisombululo se-NMP esithembekileyo sokucoca sinokunceda amashishini ukunciphisa iindleko, ukuhlangabezana neemfuno zokusingqongileyo kunye nokuzinzisa imveliso. Eli phepha lazisa iskimu se-NMP sokucoca esisebenzayo nesiphindaphindwayo, esiqinisekiswe yidatha yokwenyani yeprojekthi.

Yintoni i-NMP Distillation Equipment

Izixhobo zokunyibilikisa i-NMP sisixhobo esikhethekileyo sokubuyisa nokucoca inkunkuma ye-NMP solvent. Sisebenzisa iteknoloji yokulungisa nokwahlula ukususa umswakama kunye nokungcola kwinkunkuma, ukuze i-NMP ikwazi ukusetyenziswa kwakhona kwimveliso. Isetyenziswa kakhulu kwibhetri ye-lithium, amandla amatsha kunye neshishini leekhemikhali ze-elektroniki. Ixabiso layo eliphambili kukunciphisa iindleko zokuthenga i-solvent, ukunciphisa uxinzelelo lokukhupha ukungcola kwendalo kunye nokuphucula ucoceko kunye nokuzinza kwemveliso.

Izisombululo zoNyango lwe-NMP eziqhelekileyo

Okwangoku, kukho iindlela ezintathu eziphambili zonyango lwe-NMP kushishino. Izixhobo zemveli zokunyibilikisa ulwelo zinotyalo-mali oluphantsi, kodwa izinga lazo lokubuyisela liphantsi, ukusetyenziswa kwamandla kuphezulu kwaye umgangatho wokungcola awuzinzile. Ukucubungula ngaphandle kulula, kodwa iindleko zexesha elide ziphezulu, umngcipheko wezothutho kunzima ukuwulawula, kwaye kulula ukuyichaphazela ukuqhubeka kwemveliso. Inkqubo yokunyibilikisa ulwelo edibeneyo ye-NMP inezinga eliphezulu lokubuyisela, iindleko zokusebenza eziphantsi kunye nokuzisebenzela okuphezulu, okuye kwaba lukhetho olukhethwayo lwamashishini aphambili. Izixhobo zokunyibilikisa ulwelo ze-Pengjin NMP yinkqubo edibeneyo esebenza kakuhle kakhulu eyenzelwe iimeko zokusebenza kwebhetri ye-lithium.

Ukuthelekiswa kwezisombululo ezahlukeneyo zonyango lwe-NMP

Izixhobo zokunyibilikisa i-Pengjin NMP zinezibonelelo ezicacileyo ekusebenzeni kakuhle kokubuyisela izinto kwimeko yazo, uqoqosho lokusebenza kunye nokuziqhelanisa nemveliso enkulu, nto leyo enokuzisa iingenelo zoqoqosho ezizinzileyo zexesha elide kumashishini.

Isisombululo se-NMP Distillation esenziwe ngokwezifiso sePengjin

I-Pengjin ibonelela ngezisombululo ze-NMP ezenziwe ngokwezifiso ngokwemveliso yeshishini, uxinaniso lolwelo lwenkunkuma, iimeko zendawo kunye nemigangatho yokukhupha ukungcola. Inyathelo 1 yenza uphando kwindawo kwaye uvavanye ulwelo lwenkunkuma ukuqinisekisa iimfuno zeshishini kunye neemeko zokusebenza. Inyathelo 2 yenza uyilo olulungiselelweyo kunye nokulinganisa inkqubo ukumisela iiparameter zezixhobo kunye noyilo. Inyathelo 3 gqibezela ukwenziwa kwezixhobo, ukufakelwa kunye nokuqaliswa ukuqinisekisa ukusebenza kwenkqubo okuzinzileyo. Inyathelo 4 libonelela ngoqeqesho lwabaqhubi kunye nesikhokelo sexesha elide emva kokuthengisa. Le nkqubo idityaniswe kakhulu, kulula ukuyisebenzisa kwaye inokugcina izinga eliphezulu lokubuyisela phantsi komthwalo opheleleyo wexesha elide.

Iziphumo zeMbali yeProjekthi yokwenyani kunye neDatha

Umenzi webhetri ye-lithium ephakathi eMzantsi China ucubungula iitoni ezili-15 zenkunkuma ye-NMP ngosuku. Yayisoloko inengxaki yokulahleka kwe-solvent ephezulu, iindleko eziphezulu zonyango kunye nokukhutshwa okungazinziyo. Emva kokusebenzisa izixhobo zokunyibilikisa ze-NMP ezenzelwe wena zePengjin, izinga lokubuyisela i-NMP linyuke ukusuka kwi-78% ukuya kwi-97%, ixabiso le-solvent yemihla ngemihla lehla malunga ne-42%, ukukhutshwa kwenkunkuma kwehle ngaphezulu kwe-60%, izixhobo zinokusebenza ngokuqhubekayo iiyure ezingama-24, kwaye izinga lokusilela lingaphantsi kwe-1%. Ishishini libuyisele lonke utyalo-mali lwezixhobo kwiinyanga ezili-10.

Isiphelo

Kwibhetri ye-lithium kunye namashishini amatsha amandla, isisombululo se-NMP distillation esizinzileyo nesisebenzayo sisitshixo sokunciphisa iindleko kunye nokuphucula ukusebenza kakuhle kunye nokuthobela ukhuseleko lokusingqongileyo. Izixhobo ze-Pengjin NMP distillation ziqinisekiswe ziiprojekthi ezisebenzayo, ezinezinga eliphezulu lokubuyisela, ukusetyenziswa kwamandla okuphantsi, ukuzenzekela okuphezulu kunye nokusebenza okuthembekileyo. Zinokubonelela ngenkxaso yokubuyisela kunye nokucoca i-NMP ezinzileyo ixesha elide kumashishini. I-Pengjin izimisele ukubonelela ngoyilo olucwangcisiweyo kunye nenkonzo yomjikelo wobomi obupheleleyo kubathengi abasweleyo.
