Indlela umenzi webhethri athuthukise ngayo ukusebenza kahle kokusebenzisa kabusha i-NMP ngohlelo lokuhluza futhi Ingabe ukuhluza kwe-NMP kuba yindinganiso ekukhiqizweni kwebhethri le-lithium?
izindleko zokukhipha. Abakhiqizi abaningi abaphakathi kuya kwabakhulu babhekene nengcindezi ekhulayo yokunciphisa ukusetshenziswa kwe-solvent ngenkathi begcina ukukhiqizwa okuzinzile.
Le phrojekthi ihilela umkhiqizi webhethri le-lithium onesilinganiso sokukhiqiza esiphakathi, ikakhulukazi ekhiqiza izinto ze-cathode. Ifektri yayivele inohlelo lokubuyisa i-NMP kodwa ibhekene nezinselelo zekhwalithi yokusetshenziswa kabusha kwe-solvent kanye nokulawula izindleko, okuhlanganisa:
- I-NMP etholiwe yayiqukethe amanzi nokungcola
• Ikhwalithi yokumboza ethintekile esetshenziswa kabusha ngokuqondile
• Ukuthembela kakhulu ekuhlinzekweni kwe-solvent entsha
• Ukwelashwa kwangaphandle kukhuphule izindleko
Lezi zinkinga zivame kakhulu lapho izinhlelo zokutakula zisetshenziswa ngaphandle kokuhlanzwa okufanele.
| Isixazululo | Incazelo | Ukulinganiselwa |
| Ukusetshenziswa kabusha okuqondile | Sebenzisa kabusha isinyibilikisi esitholiwe | Ubumsulwa obuphansi, ikhwalithi engazinzile |
| Ukwelashwa okuhlinzekwa ngaphandle | Thumela isinyibilikisi ngaphandle kwendawo | Izindleko eziphakeme zesikhathi eside |
| Uhlelo lokuhluza | Ukuhlanzwa endaweni | Ukutshalwa kwezimali kokuqala okuphezulu |
Ukuze kuxazululwe lezi zinkinga, ikhambi lokuhluza elihlelekile livame ukusetshenziswa.
I-NMP etholakele iyaqoqwa futhi iqiniswe ngaphambi kokungena ohlelweni lokuhluza.
Uhlelo lusebenzisa ukucushwa kwemibhoshongo emibili noma emithathu ukususa amanzi nokungcola ngaphansi kwezimo zokushisa ezilawulwayo kanye ne-vacuum.
I-NMP ehlanziwe ibuyiselwa enkambisweni yokumboza, yakha uhlelo oluvaliwe.
Kulokhu, umenzi wamukele isisombululo se-NMP esihlanganisiwe esinikezwe umenzi wesistimu oklanyelwe yena.
Isibonelo, uhlelo lokuhluza lukaPengjin lusebenzisa ukwakheka kwemibhoshongo eminingi kanye nezimo zenqubo ezilawulwayo ukuthuthukisa ubumsulwa kanye nokuqina kwe-solvent.
Ngemva kokusetshenziswa:
• Ubumsulwa be-NMP buthuthuke kakhulu (ngokuvamile ≥99.9%)
• Okuqukethwe kwamanzi kwehliswe kwaba amazinga aphansi (isb. ≤200 ppm)
• Ukusetshenziswa kwe-solvent entsha kuncishisiwe
• Izindleko zokusebenza zizonke zehlile uma kuqhathaniswa nokwelashwa okunikezwe abantu bangaphandle
Le miphumela ihambisana nokulindelwe okuvamile embonini kwezinhlelo zokuhluza eziklanywe kahle.
- Ukubuyisela imali kuphela akwanele ukuze kuthuthukiswe izindleko
• Ukuhluzwa endaweni kuthuthukisa ukusebenza kahle kwesikhathi eside
• Ukuhlanganiswa kwesistimu kusebenza kangcono kunokuthuthukiswa kweyunithi eyodwa
Izinhlelo zokuhluza ze-NMP zibalulekile kubakhiqizi abahlose ukunciphisa izindleko zokunyibilikisa nokuthuthukisa ukuzinza kwenqubo.
Uma ukukhiqizwa kwakho sekuvele kufaka phakathi ukubuyiswa kwe-NMP kodwa kusathembele ekuphathweni kwangaphandle noma ekunyibilikeni okusha, ukuhlola ikhambi lokucwilisa elihlanganisiwe kungaba isinyathelo esilandelayo esiwusizo.
Njengoba ukukhiqizwa kwebhethri le-lithium kukhuphuka emhlabeni jikelele, ukuphathwa kwe-solvent kuba yinto ebalulekile ekulawuleni izindleko kanye nokuthobela imithetho yezemvelo.
Izinhlelo zokuhluza ze-NMP zithola ukunakwa okwengeziwe njengengxenye yalolu shintsho.
Abakhiqizi bamabhethri baqhubekela phambili ekukhiqizeni okukhulu nokujwayelekile. Ngesikhathi esifanayo, ukusetshenziswa kwe-solvent kuyanda, okwenza ukululama nokusebenzisa kabusha kubaluleke kakhulu.
I-NMP iyisisombululo esibiza kakhulu, futhi ukunciphisa inani lokuthenga kubalulekile ukuze kuzuzwe inzuzo.
Imithetho eqinile mayelana nokukhishwa kwe-VOC kanye nokuphathwa kwezinyibilikisi iyethulwa ezindaweni eziningi.
Intuthuko ekuhluzweni nasekulawulweni kwezinqubo yenza ukuhlanzwa kwendawo kuzinzile futhi kube wusizo.
Izitayela eziningana ziyacaca:
• Ukwamukelwa okuphezulu kwezinhlelo zokuxazulula izinkinga ezivaliwe
• Ukuhlanganiswa kokululama kanye nokuhluzwa
• Ukugxila okukhulu ekusebenzeni kahle kwezindleko kwesikhathi eside
• Ukuzenzakalela okwengeziwe ekuphathweni kwe-solvent
Abakhiqizi sebeqala ukushintsha kusukela “endleleni yokwelapha imfucuza” baye “endleleni yokusebenzisa kabusha imfucuza ngendlela ephumelelayo.”
Lokhu kuholela ekwandeni kwesidingo sezixazululo ezihlanganisiwe ezihlanganisa ukululama, ukuhlanza, kanye nokusetshenziswa kabusha.
Kulesi simo, ukwakheka kwezinga lesistimu kuba okubaluleke kakhulu kunokukhethwa kwemishini ngayinye.
Abahlinzeki bezixazululo abanjengoPengjin banikeza izinhlelo ze-NMP ezihlanganisiwe ezihlanganisa ukubuyisa kanye nokuhluza, okusiza abakhiqizi ukuthuthukisa ukusebenza kahle kokusebenzisa kabusha kanye nokunciphisa ukuncika kwangaphandle.
Ukuhluzwa kwe-NMP sekuyingxenye ebalulekile yokukhiqizwa kwamabhethri e-lithium anamuhla, ikakhulukazi ekukhiqizweni okukhulu.
Ezinkampanini ezihlela amandla esikhathi esizayo noma ukuthuthukisa isakhiwo sezindleko, ukuqonda nokwamukela izixazululo ezihlanganisiwe zokuphathwa kwezixazululo kunganikeza izinzuzo zesikhathi eside.
