Ezweni lanamuhla, isidingo semikhuba esimeme futhi enobungani nemvelo sesibaluleke kakhulu kunanini ngaphambili. Indawo eyodwa lapho lokhu kubaluleke khona kakhulu imboni yamakhemikhali, lapho izinyibilikisi ezifana ne-N-methyl-2-pyrrolidone (NMP) zivame ukusetshenziswa khona. I-NMP iyisinyibilikisi esisebenza kahle kakhulu, kodwa ukusetshenziswa kwayo kungaba nomthelela omubi emvelweni uma ingaphathwa kahle. Yilapho uhlelo lokutakula i-NMP luqala khona ukusebenza.

Izinhlelo zokubuyisa i-NMPzenzelwe ukubamba nokubuyisa i-NMP esetshenziswa ezinqubweni ezahlukahlukene zezimboni. Ngokwenza kanjalo, lezi zinhlelo azigcini nje ngokunciphisa inani le-NMP ekhishwa emvelweni, kodwa futhi zisiza izinkampani ukuthi zonge izindleko ngokusebenzisa kabusha izinyibilikisi. Le nzuzo ekabili yenza izinhlelo zokuvuselela i-NMP zibe yingxenye ebalulekile yokukhiqizwa kwamakhemikhali okusimeme futhi okunomthwalo wemfanelo.

Enye yezinzuzo eziyinhloko zezinhlelo zokuvuselela i-NMP ukunciphisa imfucuza. Ngokubamba nokuvuselela i-NMP, izinkampani zinganciphisa inani le-solvent ekhishwa emvelweni, ngaleyo ndlela zinciphise ingozi yokungcola nokungcola. Lokhu kubaluleke kakhulu uma kubhekwa izingozi ezingaba khona zempilo nezemvelo ezihlobene nokuchayeka ku-NMP.

Ngaphezu kwalokho,Izinhlelo zokuvuselela kabusha ze-NMPukufaka isandla ekongiweni kwezinsizakusebenza. Ngokusebenzisa kabusha i-NMP, izinkampani zinganciphisa ukuthembela kwazo ezintweni ezisetshenziswayo, zisebenzise izinsizakusebenza ngendlela ephumelelayo futhi zinciphise isidingo semikhiqizo emisha. Lokhu akugcini nje ngokuba kuhle emvelweni, kodwa futhi kusiza amabhizinisi ukunciphisa ukuthinteka kwawo kwemvelo iyonke.

Ngaphezu kwezinzuzo zemvelo, izinhlelo zokuvuselela i-NMP nazo zinezinzuzo zomnotho. Ngokusebenzisa kabusha i-NMP, izinkampani zinganciphisa isidingo sokuthenga izinyibilikisi ezintsha, ngaleyo ndlela zehlise izindleko zokusebenza. Lokhu kungabangela ukonga okukhulu kwezindleko ngokuhamba kwesikhathi, okwenza izinhlelo zokuvuselela i-NMP zibe utshalomali oluhle ngokomnotho kubakhiqizi bamakhemikhali.

Ngaphezu kwalokho, ukusebenzisa uhlelo lokuvuselela i-NMP kungathuthukisa idumela lenkampani kanye nesimo sayo embonini. Ngokubonisa ukuzibophezela ekusimeni kwemvelo kanye nemikhuba yokukhiqiza enomthwalo wemfanelo, izinkampani zingaheha amakhasimende nabalingani abaqaphela imvelo, ekugcineni ziqinise isikhundla sazo emakethe.

Ekuphetheni,Izinhlelo zokuvuselela kabusha ze-NMPzidlala indima ebalulekile ekukhuthazeni ukuzinza kwemvelo embonini yamakhemikhali. Ngokubamba nokuvuselela i-NMP, lezi zinhlelo zisiza ekunciphiseni imfucuza, ukonga izinsiza kanye nokunciphisa izindleko zokusebenza ngenkathi zinikela endaweni ehlanzekile nenempilo. Njengoba isidingo semikhuba eqhubekayo siqhubeka nokukhula, ukubaluleka kwezinhlelo zokuvuselela i-NMP akunakuphikiswana ngokweqile, okwenza zibe yingxenye ebalulekile yokukhiqizwa kwamakhemikhali okunesibopho.
