Ngokuthuthuka okusheshayo kobuchwepheshe be-vacuum, uhla olukhulayo lwezimboni - okuhlanganisa ezokukhiqiza, ezemithi, i-metallurgy, amakhemikhali, nokucubungula ukudla - zisebenzisa izinqubo ze-vacuum ukuthuthukisa ukusebenza kahle kokukhiqiza. Lokhu kwamukelwa okusabalele kuletha izimo eziyinkimbinkimbi zokusebenza zamaphampu we-vacuum, okwenza kube okufaneleukuhlunga kwe-inletesibucayi ngokuphelele. Ukukhetha izinto zokuhlunga ezifanele sekuyinto ebalulekile kubo bonke abasebenzisi.
Nokho izicelo zezimboni eziningi ziletha izimo ezinzima nakakhulu. Izinqubo ezisezingeni lokushisa eliphezulu ezifana ne-vacuum sintering kanye nokucisha (okuvame ukusebenza ku-300-800°C) zenza kokubili izihlungi zephepha neze-polyester zingasebenzi. Kulezi zindawo ezeqisayo, izihlungi zensimbi engagqwali zivela njengesixazululo esilungile. Nakuba izindleko zabo zokuqala ziphakeme futhi ukunemba kokuhlunga kuphansi kancane (imvamisa ububanzi be-micron eyi-10-15),izihlungi zensimbi ezingenasicinikeza izinzuzo ezingenakuqhathaniswa:
- Ukumelana nezinga lokushisa kufika ku-200°C
- Ukuvikeleka okuphelele kumswakama nomswakama
- Ukumelana nokugqwala ngokumelene namakhemikhali amaningi
- Idizayini esebenziseka kabusha evumela ukuhlanzwa okuphindaphindiwe
- Impilo ende yesevisi (izikhathi ezi-3-5 ubude kunezihlungi ezilahlwayo)
Ukuhlaziywa komnotho kuveza ukuthi nakuba izihlungi zensimbi engagqwali zithwala izindleko eziphakeme izikhathi ezingu-2-3, ukuqina kwazo nokukwazi ukusebenziseka kabusha kuzenza zingabizi kakhulu esikhathini esiyiminyaka emi-3, ikakhulukazi ezimeni zokusebenza ezinzima.
Ukukhetha isihlungi esilungile kudinga ukuhlolwa ngokucophelela:
- Ibanga lokushisa elisebenzayo
- Umswakama kanye nokuchayeka kwamakhemikhali
- Ukunemba kokuhlunga okudingekayo
- Amakhono okugcina
- Izindleko eziphelele zobunikazi
Njengoba ubuchwepheshe be-vacuum buqhubeka nokuvela, abakhiqizi bezihlungi bakha izixazululo eziyingxube - njengensimbi engagqwali enezikhala ze-nanofiber - ukulinganisa ukunemba nokuqina. Kodwa-ke, isimiso esiyisisekelo sihlala siwukuthi: ukufanisa izici zokuhlunga nezimo ezithile zokusebenza kuqinisekisa ukuvikelwa kwephampu okuphelele nokuthembeka kwesistimu.
