Chii chinoshandiswa neAluminium Oxide?
Alumina (Al2O3)Inoshanda sezvinhu zvakagadzirwa zvemhando yepamusoro zveceramic uye sechinhu chinoshanda mukugadzira makemikari, kusanganisira adsorbents, catalysts, microelectronics, makemikari, indasitiri yendege, nedzimwe nzvimbo dzepamusoro-soro. Hunhu hwepamusoro hunogona kupihwa nealumina hunoita kuti ive yakakodzera kushandiswa muzvishandiso zvakawanda. Mamwe emashandisirwo akajairika kunze kwekugadzirwa kwearuminiyamu akanyorwa pazasi. Fillers. Sezvo isina makemikari uye chena, aruminiyamu oxide inofarirwa nekuzadza mapurasitiki. Girazi. Mafomu mazhinji egirazi ane aruminiyamu oxide sechinhu chinosanganisa. Catalysis Aluminiyamu oxide inokonzeresa maitiro akasiyana-siyana anobatsira mumaindasitiri. Kuchenesa gasi. Aruminiyamu oxide inoshandiswa zvakanyanya kubvisa mvura kubva munzizi dzegasi. Inogumbura. Aruminiyamu oxide inoshandiswa nekuda kwekuoma kwayo uye simba rayo. Pendi. Maflakes earuminiyamu oxide anoshandiswa mupendi yekuratidzira mhedzisiro yekushongedza. Composite fiber. Aruminiyamu oxide yakashandiswa mune zvimwe zvinhu zvekuedza uye zvekutengeserana zvemashandisirwo epamusoro-soro (semuenzaniso, Fiber FP, Nextel 610, Nextel 720). Zvidziviriro zvemuviri. Zvimwe zvezvidziviriro zvemuviri zvinoshandisa mapurati e-alumina ceramic, anowanzo batanidzwa ne-aramid kana UHMWPE backing kuti zvibudirire pakurwisa njodzi dzakawanda dzepfuti. Dziviriro yeAbrasion. Aluminium oxide inogona kukura sechifukidziro paaruminiyamu neanodizing kana neplasma electrolytic oxidation. Electrical insulation. Aluminum oxide isimbi yemagetsi inoshandiswa sesubstrate (silicon on sapphire) yezvikamu zvakabatanidzwa asiwo sechidziviriro chemugero wekugadzira zvishandiso zve superconducting zvakaita se single electron transistors uye superconducting quantum interference devices (SQUIDs).
Aruminiyamu Okisijeni, sezvo iri dielectric ine band gap yakakura, inoshandiswa sechidziviriro chekudzivirira mu capacitors. Mukuvheneka, translucent aluminum oxide inoshandiswa mune mamwe marambi e sodium vapor. Aluminum oxide inoshandiswawo mukugadzirira coating suspensions mu compact fluorescent rambi. Mu chemistry laboratory, aluminum oxide inzira ye chromatography, inowanikwa mu basic (pH 9.5), acidic (pH 4.5 kana iri mumvura) uye neutral formulations. Mashandisirwo ehutano nekurapa anosanganisira sechinhu chinotsiva chiuno nemapiritsi ekudzivirira pamuviri. Inoshandiswa se scintillator uye dosimeter yekudzivirira mwaranzi uye mashandisirwo ekurapa nekuda kwe optically stimulated luminescence properties. Insulation yemaovens ekupisa kwakanyanya inowanzogadzirwa kubva ku aluminium oxide. Zvidimbu zvidiki zve aluminium oxide zvinowanzo shandiswa se boiling chips mu chemistry. Inoshandiswawo kugadzira spark plug insulators. Ichishandisa plasma spray process uye yakasanganiswa ne titania, inoputirwa pamusoro pe braking pamusoro pemamwe marimu ebhasikoro kuti ipe abrasion uye kusakara. Mazhinji e ceramic eyes pa fishing rods i denderedzwa rings dzakagadzirwa ne aluminium oxide. Muchimiro chayo cheupfu (chena) chakanakisa, chinonzi Diamantine, aruminiyamu oxide inoshandiswa senzira yepamusoro yekukwesha mawachi nekugadzira wachi. Aruminiyamu oxide inoshandiswawo mukukwesha stanchions muindasitiri yemota dzinoyambuka makomo nemabhasikoro emakomo. Kukwesha uku kunosanganiswa ne molybdenum disulfate kuti kupe mafuta kwenguva refu pamusoro.
