Mawu oyambira akupera mipira (ⅱ) - aluminium oxide ogula mpira

September 18, 2024

Mipira ya alumina ceramic ndi mtundu wofunikira wa ceramic ndipo ali m'gulu lakale. Chifukwa cha kuuma kwake koyenera, kachulukidwe kakang'ono kwambiri, kuvala kukana, kuwonongeka kwa chipongwe, ndi mtengo wotsika, komanso mipira ya zitsulo zoyambitsidwa ndi zokutira m'mafakitale monga Simenti yoyera, mchere, michere, zinthu zamagetsi, zida zamagetsi, zida zamagetsi, zokumba, ndi zotupa. Ndi sing'anga wapamwamba kwambiri. Mu zomangamanga za Cerics, kuwononga mphamvu kwa mipira ya alumina kuli kokulirapo kuposa mtundu wachilengedwe ndi miyala. Ndikuchepetsa mphamvu zapamwamba zamiyala yapamwamba kwambiri komanso kuchuluka kwa mipira wamba ya alumini, mipira ya alumina idzagwiritsidwa ntchito ndi opanga ceramic. Malinga ndi zomwe zili m'mawu osiyanasiyana a alumina, amatha kugawidwa m'masamba a alumina, sing'anga apamwamba a alumina, ndi mipira yayikulu ya alumina. Nthawi zambiri, timasankha omwe ali ndi 60% -65% alumina omwe ali ndi mipira ya alumina, omwe ali ndi zaka zambiri alumina, ndi omwe ali ndi alumina apamwamba a alumina. Mipira yayikulu ya aluminium imagawikanso mu 90 lotchedwa mu dothi, 92 lauto, 95 lauto, ndi 99 lauto. Chifukwa cha kuchuluka kwake kwapamwamba kwambiri, 99 Porcet sikupangidwa ndi opanga zazikulu, makamaka zopangidwa ndi mafakitale ena apadera.
Mipira ya malumini aluminiyamu ndi mipira yayikulu ya aluminiyamu imavomerezedwa ndi mafakitale ambiri chifukwa cha mitengo yawo yotsika, makamaka imagwiritsidwa ntchito pogaya. Mipira yayikulu ya alumina imagwiritsidwa ntchito kwambiri pakuwongolera ndi zolimba za zinthu zolimba komanso zowoneka bwino, galasi, mafakitale ambiri, kuvuta kwambiri, kudziletsa kwambiri Mphamvu yokoka, kukula kwakung'ono, kutentha kwambiri kukana, kukana kutukuka, komanso kuipitsidwa. Pakati pawo, mipira yapamwamba ya alumina yokhala ndi 92 ndi yomwe imagwiritsidwa ntchito kwambiri.
