He aha te whakamahinga o te Konumohe Waikura?
Arumina (Al2O3)Ko te rauemi mata tēnei mō te whānuitanga o ngā hua uku matatau, ā, hei matū hohe hoki i roto i te tukatuka matū, tae atu ki ngā mea mimiti, ngā mea whakakorikori, ngā hikohiko iti, ngā matū, te umanga rererangi, me ētahi atu wāhanga hangarau teitei. Ko ngā āhuatanga pai rawa atu ka taea e te alumina te tuku he mea pai mō te whakamahi i roto i ngā tono maha. Ko ētahi o ngā tono tino noa i waho o te hanga konumohe kua whakarārangihia i raro nei. Ngā Whakakī. Nā te mea he tino koretake te matū me te mā, he pai te whakakī o te waikura konumohe mō ngā kirihou. Karāhe. He maha ngā whakatakotoranga karāhe he waikura konumohe hei whakauru. Whakakorikori Ka whakakorikori te waikura konumohe i ngā momo tauhohenga e whai hua ana i roto i te ahumahi. Te purenga hau. He whānuitia te whakamahinga o te waikura konumohe hei tango i te wai mai i ngā awa hau. Te whakakoi. Ka whakamahia te waikura konumohe mō tōna pakeke me tōna kaha. Peita. Ka whakamahia ngā maramara waikura konumohe ki roto i te peita hei whakapaipai whakaata. Muka hiato. Kua whakamahia te waikura konumohe i roto i ētahi rauemi muka whakamātautau me te arumoni mō ngā tono mahi teitei (hei tauira, Muka FP, Nextel 610, Nextel 720). Pūeru tinana. Ko ētahi pūeru tinana e whakamahi ana i ngā pereti uku alumina, i te nuinga o te wā ka honoa ki te aramid, ki te tautoko UHMWPE rānei hei whakatutuki i te whai huatanga ki te nuinga o ngā tūmomo pū. Te tiaki i te pakū. Ka taea te whakatipu i te waikura konumohe hei paninga ki te konumohe mā te whakakorikori, mā te waikura hiko plasma rānei. Te whakamarumaru hiko. Ko te waikura konumohe he ārai hiko e whakamahia ana hei papa (silicon i runga i te hapaira) mō ngā ara iahiko whakauru engari hei arai kauhanga hoki mō te hanga i ngā taputapu superconducting pērā i ngā transistors irahiko kotahi me ngā taputapu pokanoa kuantum superconducting (SQUIDs).
Waikura Konumohe, he mea hiko-kore me te āputa roopu nui, ka whakamahia hei ārai ārai i roto i ngā pūnga. I roto i te whakamārama, ka whakamahia te waikura konumohe mārama i roto i ētahi rama kohu konutai. Ka whakamahia hoki te waikura konumohe hei whakarite i ngā whakatārewatanga paninga i roto i ngā rama hihiko kiato. I roto i ngā taiwhanga matū, ko te waikura konumohe he reo mō te chromatography, e wātea ana i roto i ngā hanganga taketake (pH 9.5), waikawa (pH 4.5 ina i roto i te wai) me te koretake. Kei roto i ngā tono hauora me te hauora hei rauemi i roto i ngā whakakapinga hope me ngā pire ārai whānau. Ka whakamahia hei scintillator me te ine ine mō te tiaki i te irahiko me ngā tono whakaora mō ōna āhuatanga kanapa whakaaweawe. He maha ngā wā ka hangaia te whakamarumaru mō ngā oumu pāmahana-tiketike mai i te waikura konumohe. He maha ngā wā ka whakamahia ngā wahi iti o te waikura konumohe hei maramara kohua i roto i te matū. Ka whakamahia hoki hei hanga i ngā ārai mura. Mā te whakamahi i te tukanga rehu plasma me te whakaranu ki te titania, ka pania ki runga i te mata aukati o ētahi awhi pahikara hei whakarato i te ātete ki te pakū me te kakahu. Ko te nuinga o ngā kanohi uku i runga i ngā tokotoko hī ika he mowhiti porohita i hangaia mai i te waikura konumohe. I roto i tōna āhua paura (mā) tino pai rawa atu, e kiia nei ko te Diamantine, ka whakamahia te waikura konumohe hei whakakanapa pai rawa atu i roto i te hanga wati me te hanga karaka. Ka whakamahia hoki te waikura konumohe hei paninga i ngā pou i roto i te umanga motopaika me te pahikara maunga. Ka honoa tēnei paninga ki te molybdenum disulfate hei whakarato i te hinu whakahinuhinu mō te wā roa o te mata.
