Emhlabeni wanamuhla, isidingo sezinqubo ezisimeme kanye nemvelo sibaluleke kakhulu kunangaphambili.Indawo eyodwa lapho lokhu kubaluleke kakhulu imboni yamakhemikhali, lapho izincibilikisi ezifana ne-N-methyl-2-pyrrolidone (NMP) zivame ukusetshenziswa.I-NMP iyincibilikisi esebenza kahle kakhulu, kodwa ukusetshenziswa kwayo kungaba nomthelela ongemuhle emvelweni uma ingaphathwa ngendlela efanele.Yilapho uhlelo lokutakula lwe-NMP luqala khona ukusebenza.
Amasistimu wokubuyisela we-NMPyakhelwe ukuthwebula nokubuyisela i-NMP esetshenziswa ezinqubweni ezehlukene zezimboni.Ngokwenza kanjalo, lezi zinhlelo azinciphisi kuphela inani le-NMP elikhishelwe endaweni ezungezile, kodwa futhi zisiza izinkampani zonga izindleko ngokusebenzisa kabusha izincibilikisi.Lokhu kuzuzisa okukabili kwenza izinhlelo zokuvuselela kabusha ze-NMP zibe ingxenye ebalulekile yokukhiqiza amakhemikhali okuzinzile nokunomthwalo wemfanelo.
Enye yezinzuzo ezinkulu zezinhlelo zokuvuselela kabusha ze-NMP ukunciphisa udoti.Ngokuthwebula nokuvuselela kabusha i-NMP, izinkampani zinganciphisa inani lencibilikizo ekhishelwa endaweni ezungezile, ngaleyo ndlela zehlise ingcuphe yokungcoliswa nokungcoliswa.Lokhu kubaluleke kakhulu uma kubhekwa izingozi ezingaba khona zezempilo nezemvelo ezihlobene nokuchayeka kwe-NMP.
Ngaphezu kwalokho,Amasistimu okugaya kabusha e-NMPukufaka isandla ekongiweni kwezinsiza.Ngokusebenzisa kabusha i-NMP, izinkampani zinganciphisa ukuthembela kwazo ezintweni ezingasasetshenziswa, zisebenzisa izinsiza ngokuphumelelayo futhi zinciphise isidingo semikhiqizo emisha.Akukhona nje ukuthi lokhu kuyilungele imvelo, futhi kusiza amabhizinisi ukuthi anciphise indawo yawo yonke yemvelo.
Ngaphezu kwezinzuzo zemvelo, izinhlelo zokuvuselela kabusha ze-NMP nazo zinezinzuzo zezomnotho.Ngokusebenzisa kabusha i-NMP, izinkampani zinganciphisa isidingo sokuthenga izinyibilikisi ezintsha, ngaleyo ndlela zehlise izindleko zokusebenza.Lokhu kungaholela ekongeni kwezindleko ezibalulekile ngokuhamba kwesikhathi, okwenza izinhlelo zokubuyisela i-NMP zibe ukutshalwa kwezimali okuhle kwezomnotho kubakhiqizi bamakhemikhali.
Ukwengeza, ukusebenzisa uhlelo lokugaywa kabusha kwe-NMP kungathuthukisa isithunzi nesimo senkampani embonini.Ngokubonisa ukuzibophezela ekusimamiseni imvelo kanye nezinqubo zokukhiqiza ezinomthwalo wemfanelo, izinkampani zingaheha amakhasimende aqaphela imvelo nozakwethu, ekugcineni ziqinise isikhundla sabo emakethe.
Ekuphetheni,Amasistimu okugaya kabusha e-NMPukudlala indima ebalulekile ekukhuthazeni ukusimama kwemvelo embonini yamakhemikhali.Ngokuthwebula kanye nokuvuselela i-NMP, lezi zinhlelo zisiza ukunciphisa ukumosha, ukonga izinsiza kanye nokunciphisa izindleko zokusebenza kuyilapho zifaka isandla endaweni ehlanzekile, enempilo.Njengoba isidingo sezinqubo ezisimeme sikhula, ukubaluleka kwezinhlelo zokuvuselela kabusha ze-NMP angeke zeqiswe, okuzenza zibe yingxenye ebalulekile yokukhiqiza amakhemikhali okunomthwalo wemfanelo.
