Ezinqubweni zezimboni, ukusetshenziswa kwezinyibilikisi kuvame ukuba yinto ebalulekile emisebenzini eyahlukahlukene. Kodwa-ke, ukwelashwa komoya oqukethe izinyibilikisi kungaba yinselele kwezemvelo nakwezomnotho. Yilapho izinhlelo zokubuyisa i-NMP (N-methyl-2-pyrrolidone) zisebenza khona, zinikeza ikhambi eliqhubekayo lokuphathwa kwezinyibilikisi.

I-NMP iyisithako esiwusizo esisetshenziswa kabanzi ezimbonini ezifana nemithi, izinto zikagesi kanye namakhemikhali kaphethroli. Ukuqina kwayo okuphezulu kanye nokuguquguquka okuphansi kwenza kube kuhle kakhulu ezinhlotsheni eziningi zokusebenza. Kodwa-ke, izindleko zayo eziphakeme kanye nomthelela wayo emvelweni kwenza ukubuyiswa kanye nokusetshenziswa kabusha kwe-NMP emifuleni yegesi ezinqubweni zezimboni kubaluleke kakhulu.

Izinhlelo zokubuyisa i-NMPzenzelwe ukubamba nokuhlukanisa i-NMP emoyeni oqukethe i-solvent ngempumelelo ukuze zisetshenziswe kabusha ezinqubweni. Lokhu akusizi nje kuphela ukunciphisa ukusetshenziswa kwe-NMP iyonke, kodwa futhi kunciphisa umthelela wemvelo ohlotshaniswa nokulahlwa kwayo. Umoya ohlanzekile ogcwele i-solvent ungabuyiselwa enqubweni noma ukhishwe umoya emoyeni, kuye ngezidingo zamakhasimende.

Enye yezinzuzo eziyinhloko zohlelo lokuvuselela i-NMP ngumnikelo walo emikhubeni eqhubekayo emisebenzini yezimboni. Ngokusebenzisa lolu hlelo, izinkampani zinganciphisa kakhulu ukusetshenziswa kwe-solvent, ngaleyo ndlela zonge izindleko futhi zinciphise ukuthinteka kwazo kwemvelo. Ngaphezu kwalokho, ukubuyiselwa kanye nokuvuselelwa kwe-NMP kuhambisana nezimiso zomnotho ojikelezayo, okuwukusebenzisa izinsiza ngendlela efanele nokunciphisa imfucuza.

Ngaphezu kwalokho, izinhlelo zokuvuselela i-NMP zinikeza izixazululo ezisebenzayo zokuthobela imithetho. Njengoba kugxilwe kakhulu emithethweni yezemvelo kanye nezindinganiso zokukhipha ukungcola, izimboni zingaphansi kwengcindezi yokuphatha ngempumelelo ukukhishwa kwe-solvent. Ngokutshala imali ohlelweni lokuvuselela i-NMP oluthembekile, izinkampani zingaqinisekisa ukuthi ziyahlangabezana nezidingo zokuthobela imithetho ezidingekayo ngenkathi zibonisa ukuzibophezela kwazo ekuphatheni imvelo.

Ngaphezu kwezinzuzo zemvelo nezomthetho, izinhlelo zokuvuselela i-NMP nazo ziletha izinzuzo zomnotho emabhizinisini. Ngokusebenzisa kabusha i-NMP futhi, izinkampani zinganciphisa ukuthembela kwazo ekuthengweni kwe-solvent okungeyona i-virgin, zisindise izindleko ngokuhamba kwesikhathi. Ngaphezu kwalokho, ukuphathwa kahle kwe-solvents kunegalelo ekwenzeni ngcono inqubo yonke kanye nokwandisa ukusebenza kahle.

Kubalulekile ukuqaphela ukuthi ukusetshenziswa kwezinhlelo zokubuyisa i-NMP kudinga ukucatshangelwa ngokucophelela izidingo ezithile zenqubo kanye nokwenzeka kobuchwepheshe. Izici ezifana nomthamo womoya oqukethe i-solvent, ukuhlushwa kwe-NMP, kanye nezimo zenqubo iyonke kudingeka zihlolwe ukuze kuklanywe ikhambi elenziwe ngokwezifiso elizohlinzeka ngemiphumela emihle kakhulu.

Ngokufigqiwe,Izinhlelo zokubuyisa i-NMPukuhlinzeka ngendlela eqhubekayo nengabizi kakhulu yokuphathwa kwe-solvent ezindaweni zezimboni. Ngokubamba nokubuyisa i-NMP emoyeni, uhlelo lusekela imigomo yezemvelo, ukuthobela imithetho kanye nezinzuzo zomnotho. Njengoba imboni iqhubeka nokubeka phambili ukusimama nokusebenza kahle kwezinsizakusebenza, ukwamukelwa kwezinhlelo zokuvuselela i-NMP kuzodlala indima ebalulekile ekwakheni ikusasa eliluhlaza, elinomthwalo wemfanelo kakhudlwana lokuphathwa kwe-solvent.
