Kodi aluminium oxide amagwiritsidwa ntchito bwanji?
Alumina (al2o3)Amagwira ntchito ngati zopangira zadongosolo zazogulitsa zapamwamba komanso monga wothandizira mankhwala, kuphatikiza adsorbents, othandizira, mankhwala, malo ena a Arospace. Makhalidwe apamwamba a Alumina atha kupereka kuti ndi abwino kugwiritsa ntchito mu mapulogalamu ambiri. Zina mwazomwe zimagwiritsidwa ntchito kwambiri kunja kwa kapangidwe ka aluminiyamu zalembedwa pansipa. Mafilimu. Kukhala ndi mankhwalawa komanso oyera, aluminiyamu oxide ndi ophikira bwino kwa pulasitiki. Mapangidwe agalasi. Catalysis aluminiyamu otum yomwe imachitika zosiyanasiyana zomwe ndizothandiza mafakitale. Kuyeretsa mpweya. Aluminiyamu oxide amagwiritsidwa ntchito pochotsa madzi m'mitsinje yamagesi. Abrasive. Aluminiyamu oxide amagwiritsidwa ntchito polimbana ndi kuuma kwake. Utoto. Ma flakesi otumba a aluminium osungiramo amagwiritsidwa ntchito pa utoto wopangira zokongoletsera. Fiber. Aluminiyamu oxide wagwiritsidwa ntchito muzinthu zochepa zoyeserera komanso zamalonda pazogwiritsa ntchito kwambiri (mwachitsanzo, fiber FP, nextel 610, nextel 720). Zida zathupi. Chitetezo cha Abrasiation. Aluminiyamu oxide amatha kukhala okhwima pa aluminiyamu mwa kuyika kapena ndi plasma electrolytic. Kutulutsa kwamagetsi. Aluminiyamu oxide ndi gawo lamagetsi lomwe limagwiritsidwa ntchito ngati gawo lapansi (silicon pa safiro) la zigawo zophatikizira komanso zida zapamwamba za elekitikizo ndi zida zapamwamba (squids).
Aluminiyumu oxide, pokhala diect diect ndi gulu lalikulu la band, limagwiritsidwa ntchito ngati chotchinga mu Cavitors. Powunikira, ma translucem aluminiyamu oxide amagwiritsidwa ntchito mu nyali za vayamu za vayamu. Aluminiyamu oxide imagwiritsidwanso ntchito pokonzekera kufananizidwa mu nyali za flurescent. Mu chimanga chogwirira ntchito, aluminiyamu oxide ndi sing'anga ya chromatography. Zaumoyo ndi zamankhwala zimaphatikizapo monga mfundo m'chiuno m'malo mwa m'chiuno komanso mapiritsi oletsa kubala. Amagwiritsidwa ntchito ngati chotetezera cha radidetillator ndi ma radiation omwe amagwiritsidwa ntchito ndi mankhwala a mankhwalawa olimbikitsidwa kwambiri. Kukopa kwa mafupa ambiri otentha nthawi zambiri kumapangidwa kuchokera ku aluminiyamu ma oxide. Zidutswa zazing'ono za aluminiyamu oxide nthawi zambiri zimagwiritsidwa ntchito ngati tchipisi owotcha mu chemistry. Amagwiritsidwanso ntchito popanga ma spark. Kugwiritsa ntchito njira yopumira plasma ndikusakanikirana ndi Titania, kumakutidwa ndi malo obowola njinga zanjinga kuti apereke abrasion ndi kuvala kukana. Maso ambiri a ceramic pa ndodo zasodzi ndi mphete zozungulira zopangidwa ndi aluminiyamu. Mu mawonekedwe ake abwino kwambiri (oyera), otchedwa diamantine, aluminiyamu oxide amagwiritsidwa ntchito ngati chopondera kwambiri popendekera komanso otchi. Aluminiyamu oxide imagwiritsidwanso ntchito pokutidwa ndi ma stannions mu makampani a njinga yamoto ndi mapiri. Kulumikizana uku kumaphatikizidwa ndi Molybdenum kukhumudwitsanso kupaka mafuta.
