Indlela umenzi webhetri ayiphucule ngayo indlela yokusebenzisa i-NMP kakuhle ngenkqubo yokuhluza kwaye Ngaba i-NMP distillation iba ngumgangatho kwimveliso yebhetri ye-lithium?
iindleko zokucima. Abavelisi abaninzi abaphakathi ukuya kwabakhulu bajongene noxinzelelo olukhulayo lokunciphisa ukusetyenziswa kwesinyibilikisi ngelixa begcina imveliso ezinzileyo.
Le projekthi ibandakanya umenzi webhetri ye-lithium enemveliso ephakathi, ikakhulu evelisa izixhobo ze-cathode. Umzi-mveliso sele unenkqubo yokubuyisela i-NMP kodwa ujongene nemingeni yomgangatho wokusetyenziswa kwakhona kwe-solvent kunye nolawulo lweendleko, kuquka:
- I-NMP efunyenweyo yayinamanzi kunye nokungcola
• Ukuphinda usebenzise ngokuthe ngqo umgangatho wokugquma ochaphazelekileyo
• Ukuxhomekeka kakhulu ekufumaneni isinyibilikisi esitsha
• Unyango oluvela ngaphandle lunyuse iindleko
Ezi ngxaki zixhaphakile xa kusetyenziswa iinkqubo zokubuyisela izinto kwimeko yesiqhelo ngaphandle kokucoca ngokufanelekileyo.
| Isisombululo | Inkcazo | Umda |
| Ukuphinda usebenzise ngokuthe ngqo | Sebenzisa kwakhona isinyibilikisi esifunyenweyo | Ubumsulwa obuphantsi, umgangatho ongaguqukiyo |
| Unyango oluvela ngaphandle | Thumela isinyibilikisi ngaphandle kwendawo | Ixabiso eliphezulu lexesha elide |
| Inkqubo yokunyibilikisa | Ukucocwa kwindawo | Utyalo-mali lokuqala oluphezulu |
Ukujongana nale micimbi, isisombululo se-distillation esakhiweyo sidla ngokusetyenziswa.
I-NMP efunyenweyo iyaqokelelwa ize izinziswe ngaphambi kokuba ingene kwinkqubo yokunyibilikisa.
Le nkqubo isebenzisa ulwakhiwo lwemibhoshongo emibini okanye emithathu ukususa amanzi kunye nokungcola phantsi kweemeko zobushushu ezilawulwayo kunye ne-vacuum.
I-NMP ecocekileyo ibuyiselwa kwinkqubo yokugquma, yenze inkqubo evaliweyo.
Kule meko, umenzi wamkela isisombululo se-NMP esidibeneyo esibonelelwe ngumvelisi wenkqubo eyenzelwe wena.
Umzekelo, inkqubo yokunyibilikisa kaPengjin isebenzisa uyilo lweenqaba ezininzi kunye neemeko zenkqubo ezilawulwayo ukuphucula ubunyulu kunye nozinzo lwesinyibilikisi.
Emva kokuphunyezwa:
• Ubumsulwa be-NMP buphucuke kakhulu (ngesiqhelo ≥99.9%)
• Umthamo wamanzi wehlisiwe ukuya kumanqanaba aphantsi (umz. ≤200 ppm)
• Ukusetyenziswa kwesinyibilikisi esitsha kuncitshisiwe
• Iindleko zokusebenza zizonke zehlile xa kuthelekiswa nonyango oluvela ngaphandle
Ezi ziphumo zihambelana nolindelo oluqhelekileyo kushishino kwiinkqubo zokunyibilikisa ezenziwe kakuhle.
- Ukubuyiselwa kwemali kukodwa akwanelanga ukuphucula iindleko
• Ukuhluzwa kwindawo ethile kuphucula ukusebenza kakuhle kwexesha elide
• Ukuhlanganiswa kwenkqubo kusebenza ngakumbi kunokuphuculwa kweyunithi enye
Iinkqubo zokunyibilikisa i-NMP zibalulekile kubavelisi abajonge ukunciphisa iindleko zesinyibilikisi nokuphucula uzinzo lwenkqubo.
Ukuba imveliso yakho sele iquka ukubuyiswa kwe-NMP kodwa isaxhomekeke kunyango lwangaphandle okanye kwisinyibilikisi esitsha, ukuvavanya isisombululo se-distillation esidibeneyo kunokuba linyathelo elilandelayo elisebenzayo.
Njengoko imveliso yebhetri ye-lithium isanda kwihlabathi liphela, ulawulo lwe-solvent luba yinto ephambili ekulawuleni iindleko kunye nokuthobela imiqathango yokusingqongileyo.
Iinkqubo zokunyibilikisa i-NMP zifumana ingqwalasela engakumbi njengenxalenye yolu tshintsho.
Abavelisi beebhetri basondela kwimveliso enkulu nesemgangathweni ngakumbi. Kwangaxeshanye, ukusetyenziswa kwe-solvent kuyanda, nto leyo eyenza ukubuyiselwa kunye nokusetyenziswa kwakhona kubaluleke ngakumbi.
I-NMP sisinyibilikisi esibiza kakhulu, kwaye ukunciphisa umthamo wokuthenga kubalulekile ukuze kuzuzwe inzuzo.
Imithetho engqongqo malunga nokukhutshwa kwe-VOC kunye nokuphathwa kwezinyibilikisi iqalisiwe kwiindawo ezininzi.
Inkqubela phambili ekuhluzweni nasekulawulweni kweenkqubo zenza ukucocwa kwendawo kube lula kwaye kube luncedo.
Iindlela ezahlukeneyo ziya zicaca:
• Ukusetyenziswa okuphezulu kweenkqubo zesinyibilikisi ezivaliweyo
• Ukuhlanganiswa kokubuyiselwa kunye nokucoca
• Ukugxila okwandisiweyo ekusebenzeni kakuhle kweendleko ixesha elide
• Ukuzenzekela okungakumbi kulawulo lwe-solvent
Abavelisi baqala ukutshintsha ukusuka “kwindlela yokuphatha isinyibilikisi senkunkuma” ukuya “kwindlela yokusebenzisa kwakhona isinyibilikisi ngokufanelekileyo.”
Oku kukhokelela ekwandeni kwemfuno yezisombululo ezidibeneyo ezidibanisa ukubuyiselwa, ukucoca, kunye nokuphinda kusetyenziswe.
Kule meko, uyilo lwenqanaba lenkqubo luba lubaluleke ngakumbi kunokukhethwa kwezixhobo zomntu ngamnye.
Ababoneleli ngezisombululo ezifana nePengjin banikezela ngeenkqubo ze-NMP ezidibeneyo ezidibanisa ukubuyiswa kunye nokuhluzwa, ukunceda abavelisi ukuphucula ukusebenza kakuhle kokusetyenziswa kwakhona kunye nokunciphisa ukuxhomekeka kwangaphandle.
Ukwenziwa kwe-NMP distillation kuya kuba yinxalenye ebalulekileyo yokwenziwa kweebhetri ze-lithium zanamhlanje, ingakumbi kwimveliso enkulu.
Kwiinkampani ezicwangcisa amandla exesha elizayo okanye ukuphucula ulwakhiwo lweendleko, ukuqonda nokwamkela izisombululo ezidibeneyo zolawulo lwe-solvent kunokubonelela ngeenzuzo zexesha elide.
