Vacuum sintering ndi ukadaulo wopanga ma billet a ceramic pa vacuum. Imatha kuwongolera kaboni wazinthu zopangira, kukonza chiyero cha zinthu zolimba komanso kuchepetsa kutulutsa kwamafuta. Poyerekeza ndi sintering wamba, vacuum sintering akhoza bwino kuchotsa mpweya adsorbed, kusintha zinthu chiyero, ndi kukwaniritsa sintering pa kutentha osiyanasiyana.
Tonse tikudziwa kuti pampu ya vacuum ndi chida chofunikira kugwiritsa ntchito vacuum sintering. Komabe, ufa wochuluka udzapangidwa panthawi ya sintering.Ufawu udzatha pampu ndikuipitsa mafuta a pampu ngati akuyamwa mu mpope. Chifukwa chake, ndikofunikira kugwiritsa ntchitofyuluta yolowerakusefa ufa ndikuteteza pampu ya vacuum.
Zosefera zambiri zolowera zimatha kuwoneka chimodzimodzi kunja, koma zosefera mkati zitha kupangidwa ndi zinthu zosiyana kwambiri. Pamafafa ang'onoang'ono, nthawi zambiri timagwiritsa ntchito zosefera zopangidwa ndi pepala lazamkati lamatabwa ndi nsalu za polyester zosalukidwa kuti zisefe. Komabe, mitundu iwiriyi ya zinthu zosefera sizoyenera kutengera vacuum sintering chifukwa siimatha kutentha kwambiri. Amangogwira ntchito ku kutentha kosachepera madigiri 100 Celsius. Chifukwa chake njira yosinthira vacuum sintering idzagwiritsa ntchito zosefera zazitsulo zosapanga dzimbiri zosapanga dzimbiri. Kuphatikiza apo, chotchinga cha inlet fyuluta nthawi zambiri chimapangidwa ndi chitsulo cha kaboni, koma chopondera chomwe chimagwiritsidwa ntchito mu vacuum sintering chimapangidwa ndi chitsulo chosapanga dzimbiri komanso zinthu zake. Koma chifukwa cha kuchepa kwa ma gaskets osindikiza ndi guluu, zinthu zosefera zitsulo zosapanga dzimbiri ndizoyenera kutentha kosachepera madigiri 200 Celsius. Ngati malo ogwirira ntchito ali pamwamba pa 200 digiri Celsius, m'pofunika kuganizira kukhazikitsa zipangizo zoziziritsira.
LVGEfufuzani nthawi zonse zofuna za msika ndikusintha zinthu zathu potumikira makasitomala. Ngati muli ndi zosowa kapena malingaliro, chonde omasuka kukambirana nafe. Tiyeni tilimbikitse chitukuko cha mafakitale osefera vacuum pamodzi!
