Kodi Aluminiyamu Oxide Amagwiritsidwa Ntchito Bwanji?
Alumina (Al2O3)imagwira ntchito ngati zida zopangira zinthu zambiri zapamwamba zadothi komanso ngati chothandizira pakukonza mankhwala, kuphatikiza ma adsorbents, chothandizira, ma microelectronics, mankhwala, mafakitale apamlengalenga, ndi malo ena apamwamba kwambiri.Makhalidwe apamwamba a alumina angapereke kuti akhale abwino kuti agwiritsidwe ntchito pazinthu zambiri.Zina mwazogwiritsidwa ntchito kwambiri kunja kwa kupanga aluminiyamu zalembedwa pansipa.Zodzaza.Pokhala wodziyimira pawokha komanso woyera, aluminiyamu oxide ndi chodzaza ndi mapulasitiki.Galasi.Magalasi ambiri amakhala ndi aluminium oxide ngati chopangira.Catalysis Aluminiyamu okusayidi imathandizira machitidwe osiyanasiyana omwe ndi othandiza m'mafakitale.Kuyeretsa gasi.Aluminium oxide imagwiritsidwa ntchito kwambiri kuchotsa madzi mumitsinje ya gasi.Zonyansa.Aluminium oxide imagwiritsidwa ntchito chifukwa cha kuuma kwake komanso mphamvu zake.Penta.Aluminium oxide flakes amagwiritsidwa ntchito mu utoto kuti awonetse kukongoletsa.Compositi fiber.Aluminium oxide yakhala ikugwiritsidwa ntchito muzinthu zochepa zoyesera komanso zamalonda pazogwiritsa ntchito kwambiri (mwachitsanzo, Fiber FP, Nextel 610, Nextel 720).Zida zina za thupi zimagwiritsa ntchito mbale za alumina ceramic, nthawi zambiri kuphatikiza ndi aramid kapena UHMWPE kuthandizira kuti zitheke bwino polimbana ndi ziwopsezo zambiri zamfuti.Chitetezo cha abrasion.Aluminium oxide imatha kukulitsidwa ngati zokutira pa aluminiyamu mwa anodizing kapena ndi plasma electrolytic oxidation.Kutsekereza magetsi.Aluminium oxide ndi insulator yamagetsi yomwe imagwiritsidwa ntchito ngati gawo lapansi (silicon pa safiro) popanga mabwalo ophatikizika komanso ngati chotchinga chotchinga pakupanga zida zapamwamba kwambiri monga ma electron transistors amodzi ndi zida za superconducting quantum interference (SQUIDs).
Aluminium oxide, pokhala dielectric yokhala ndi kusiyana kwakukulu kwa bandi, imagwiritsidwa ntchito ngati chotchinga chotchinga mu ma capacitors.Powunikira, translucent aluminium oxide imagwiritsidwa ntchito mu nyali zina za sodium vapor.Aluminiyamu okusayidi amagwiritsidwanso ntchito pokonzekera kuyimitsidwa ❖ kuyanika mu nyali yaying'ono fulorosenti.M'ma laboratories a chemistry, aluminiyamu okusayidi ndi sing'anga ya chromatography, yomwe imapezeka mu Basic (pH 9.5), acidic (pH 4.5 ikakhala m'madzi) ndi kusalowerera ndale.Ntchito zaumoyo ndi zachipatala zimaphatikizirapo ngati zida zosinthira m'chiuno ndi mapiritsi oletsa kubereka.Imagwiritsidwa ntchito ngati scintillator ndi dosimeter poteteza ma radiation ndi ntchito zochizira pamawonekedwe ake owoneka bwino a luminescence.Kutentha kwa ng'anjo zotentha kwambiri nthawi zambiri kumapangidwa kuchokera ku aluminium oxide.Tizidutswa tating'ono ta aluminium oxide nthawi zambiri amagwiritsidwa ntchito ngati tchipisi towiritsa mu chemistry.Amagwiritsidwanso ntchito popanga ma spark plug insulators.Pogwiritsa ntchito kupopera kwa madzi a m'magazi ndi kusakaniza ndi titania, amakutidwa pamwamba pa mabuleki a njinga zina kuti zisawonongeke komanso kuti asavale.Maso ambiri a ceramic pa ndodo zophera nsomba ndi mphete zozungulira zopangidwa kuchokera ku aluminium oxide.Mu mawonekedwe ake abwino kwambiri a ufa (woyera), otchedwa Diamantine, aluminiyamu okusayidi amagwiritsidwa ntchito ngati kupukuta kwapamwamba pakupanga mawotchi ndi kupanga mawotchi.Aluminium oxide imagwiritsidwanso ntchito popaka ma stanchions mumtanda wamagalimoto ndi njinga zamapiri.Kupaka uku kumaphatikizidwa ndi molybdenum disulfate kuti apereke mafuta opaka nthawi yayitali padziko lapansi.
