I-vacuum sintering ubuchwepheshe bokufaka amabhilidi e-ceramic ku-vacuum. Ingakwazi ukulawula okuqukethwe kwekhabhoni yezinto ezingavuthiwe, ithuthukise ubumsulwa bezinto eziqinile futhi inciphise i-oxidation yomkhiqizo. Uma kuqhathaniswa ne-sintering evamile, i-vacuum sintering ingasusa kangcono amagesi adsorbed, ithuthukise ubumsulwa bezinto ezibonakalayo, futhi izuze ukucwiliswa emazingeni okushisa ahlukahlukene.
Sonke siyazi ukuthi i-vacuum futha iyisisetshenziswa esibalulekile sokusebenzisa i-vacuum sintering. Kodwa-ke, inani elikhulu le-powder lizokhiqizwa ngesikhathi senqubo ye-sintering.I-powder izoguga ipompo futhi ingcolise amafutha epompo uma idonswa empompo. Ngakho-ke, kuyadingeka ukusebenzisa i-anisihlungi sokungenaukuhlunga impushana futhi uvikele futha vacuum.
Izihlungi eziningi zokungena zingabukeka zifana ngaphandle, kodwa ingxenye yokuhlunga ngaphakathi ingase yenziwe ngezinto ezihluke ngokuphelele. Ukuze uthole izimpushana ezincane, ngokuvamile sisebenzisa izakhi zokuhlunga ezenziwe ngephepha le-pulp lezinkuni kanye nendwangu ye-polyester engalukiwe yokuhlunga. Kodwa-ke, lezi zinhlobo ezimbili zezinto zokuhlunga aziyilungele inqubo ye-vacuum sintering ngoba azikwazi ukumelana nezinga lokushisa eliphezulu. Asebenza kuphela emazingeni okushisa angaphansi kuka-100 degrees Celsius. Ngakho-ke inqubo ye-vacuum sintering izosebenzisa ama-elementi okuhlunga ensimbi engenasici. Ngaphezu kwalokho, i-casing yesihlungi se-inlet ngokuvamile senziwa nge-carbon steel, kodwa i-casing esetshenziselwa inqubo ye-vacuum sintering yenziwe ngensimbi engagqwali kanye nezinto zayo. Kodwa ngenxa yemikhawulo yokuvala ama-gaskets kanye neglue, izakhi zokuhlunga insimbi engagqwali zifaneleka kuphela emazingeni okushisa angaphansi kuka-200 degrees Celsius. Uma indawo yokusebenza ingaphezu kuka-200 degrees Celsius, kuyadingeka ukuthi ucabangele ukufaka izinto zokupholisa.
I-LVGEhlola njalo izimfuno zemakethe futhi uthuthukise imikhiqizo yethu ngenkathi sisebenzela amakhasimende. Uma unezidingo noma iziphakamiso, sicela ukhululeke ukuxoxa nathi. Masikhuthaze ukuthuthukiswa kwemboni yokuhlunga kwe-vacuum ndawonye!
