Ndi kupita patsogolo kofulumira kwaukadaulo wa vacuum, mafakitale akuchulukirachulukira - kuphatikiza opanga, opanga mankhwala, zitsulo, mankhwala, ndi kukonza zakudya - akutenga njira zopumira kuti apititse patsogolo kupanga bwino. Kutengera kufalikira kumeneku kumabweretsa zovuta zogwirira ntchito pamapampu a vacuum, kupanga zoyenerakusefera kolowerawotsutsa mwamtheradi. Kusankha zosefera zoyenera kwakhala chinthu chofunikira kwa ogwiritsa ntchito onse.
Komabe ntchito zambiri zamafakitale zimapereka zovuta kwambiri. Njira zotentha kwambiri monga vacuum sintering ndi kuzimitsa (zomwe zimagwira ntchito pa 300-800 ° C) zimapangitsa kuti zosefera zamapepala ndi poliyesi zikhale zopanda ntchito. Pamalo ovutawa, zinthu zosefera zitsulo zosapanga dzimbiri zimatuluka ngati njira yabwino kwambiri. Ngakhale mtengo wawo woyamba ndi wapamwamba komanso kusefera kutsika pang'ono (nthawi zambiri 10-15 micron range),zosefera zitsulo zosapanga dzimbiriperekani zabwino zosayerekezeka:
- Kutentha kwapakati mpaka 200 ° C
- Chitetezo chokwanira ku chinyezi ndi chinyezi
- Kukana dzimbiri motsutsana ndi mankhwala ambiri
- Mapangidwe osinthika amalola kuyeretsa mobwerezabwereza
- Moyo wautali wautumiki (nthawi 3-5 kutalika kuposa zosefera zotayidwa)
Kusanthula kwachuma kukuwonetsa kuti ngakhale zosefera zazitsulo zosapanga dzimbiri zimanyamula mtengo wokwera nthawi 2-3, kukhazikika kwawo ndi kusinthikanso kumawapangitsa kukhala okwera mtengo kwambiri pazaka zitatu, makamaka m'malo ovuta kwambiri.
Kusankha zosefera zoyenera kumafuna kuunika mozama kwa:
- Opaleshoni kutentha osiyanasiyana
- Chinyezi ndi kukhudzana ndi mankhwala
- Zofunika kusefera mwatsatanetsatane
- Maluso osamalira
- Ndalama zonse za umwini
Pamene ukadaulo wa vacuum ukupitilira kusinthika, opanga zosefera akupanga mayankho osakanizidwa - monga ma mesh osapanga dzimbiri okhala ndi zokutira za nanofiber - kuti azitha kulondola komanso kulimba. Komabe, mfundo yofunikira ikadalipo: kufananiza mawonekedwe a fyuluta ndi momwe amagwirira ntchito kumatsimikizira chitetezo chokwanira cha pampu ndi kudalirika kwadongosolo.
