Te Mahi a te Paura Alumina hei Tautoko Whakaoho
Ina kōrerohia te umanga matū, inā koa te mara o te whakaterenga, he nui ngā mea e pā ana ki tēnei. I tēnei rā, kāore tātou e kōrero mō aua wāhanga whakarewa hohe kounga teitei, whakahihiri, engari ko te "toa kāore i te tino mōhiotia" engari he mea nui rawa atu - te paura alumina. He rite ki te pou o te atamira, ki te turanga rānei o te whare; ko te pai o te mahi a ngā wāhanga hohe, arā, aua "whetu", e whakawhirinaki ana ki te pai o te hanganga o te atamira.
I taku tīmatanga ki tēnei mara, i kite ahau he mea rerekē—he ahakonumoheIna koa? Kāore i te tino miharo te ahua, nō reira he aha i tino nui ai tōna tūranga i roto i te umanga tautoko whakakorikori? I muri mai, i muri i te noho roa me ngā kaimahi mātau i roto i te taiwhanga me te awheawhe, ka āta mārama ahau. Ehara i te mea ko te kōwhiringa "pai rawa atu", engari ko te kōwhiringa "tino taurite" i kitea i waenga i te mahi, te utu, me te tono mahi. He rite tēnei ki te hoko waka; kāore e hiahiatia ana e tātou te mea tere rawa atu, engari ko tētahi e taurite ana i te whai huatanga o te wahie, te wāhi, te roa, me te utu. I roto i te umanga kawe, he rite te alumina ki taua "mea katoa" - he iti noa ngā ngoikoretanga me ngā kaha tino pai.
Tuatahi, me whakanui tātou i tōna kounga "hautai pūangi"—he whānui te mata, ā, he tino kaha te tipu.
Koinei te kaha matua opaura konumoheKaua e whakaaro he paraoa mārō, matotoru hoki tēnei e whakamahia ana e koe i te kāinga. Whai muri i te tukatuka motuhake, ka kī tonu te roto o te kawe alumina i ngā pore iti me ngā awaawa i te nanoscale. Ka kiia tēnei hanganga ko te "rahi motuhake o te horahanga mata".
Hei tauira, kotahi karamu o te paura alumina kounga teitei, mēnā ka whānui katoa ngā pūwero o roto, ka taea te eke ki ngā rau mita pūrua te horahanga o te mata—he nui ake i te papa poitūkohu! Whakaarohia te maha o ngā wāhanga hohe whakakorikori (pērā i te konupūmā, te palladium, me te nickel) ka taea te whakanoho ki roto i tētahi "rohe" nui! He rite ki te whakarato i ngā wāhanga hohe ki tētahi "whare moe" tino nui, he pai te whakapaipai, e āhei ai rātou ki te horapa ōrite me te karo i te piri tahi, kia nui ake ai te pānga me te pa atu ki ngā matū tauhohe. Mā tēnei ka tino whakarite te whai huatanga o te whakakorikori.
Heoi anō, ka taea te "whakariterite" i te hanganga o ngā pūwero o tēnei "hautai". Mā te whakarerekē i te tukanga whakarite, ka taea e tātou te whakahaere i te rahi, te tohatoha, me te āhua o ōna pūwero ki tētahi taumata, pērā i te uku whakarewa. He nui ētahi ngota matū tauhohe, ā, me nui ake ngā "tatau" hei tomo; he tere ētahi tauhohe, ā, me poto ake ngā pūwero kia kore ai e ngaro i roto i te arai. Ka taea e te tautoko alumina te whakatutuki pai i ēnei "hiahia whaiaro," he ngāwari kāore e taea te whakataurite ki ētahi atu rauemi.
Tuarua, he mea tika kia whakahuatia tōna "āhua pai"—he tino pai te pumau matū me te kaha ā-ringa.
Kāore i te tino pai te taiao e noho ana ngā whakakorikori. He maha ngā wā he teitei te pāmahana me te pēhanga, ā, i ētahi wā ka pāngia e ngā hau waikura. Whakaarohia mēnā ko te tautoko tonu he "whāinga ngohengohe," ka pakaru i roto i ngā rā e rua i roto i te tauhohenga, ka tauhohe rānei ki ngā matū me ngā matū hohe - kāore ianei e pōrearea ngā mea katoa?
I tēnei āhuatanga, he tino "pūmau" te paura alumina. Ka mau tonu tōna hanganga tioata ahakoa i ngā pāmahana teitei, ka ātete ki te hinga, ā, he "koretake" ōna āhuatanga matū, kāore e tere te tauhohe ki ētahi atu matū. Mā tēnei ka roa te ora o te whakakorikori, ka penapena i te wā kore mahi me ngā utu whakakapinga o ngā wheketere.
Hei tāpiri atu, whakaarohia te kaha ā-mīhini. I roto i ngā tauhohenga ahumahi, kāore ngā whakakorikori e takoto noa; me tu tonu i te pānga o te hau, te waku i waenga i ngā matūriki, tae noa ki te takahurihuri i roto i te moenga e neke ana. Ki te kore e ranea te kaha, ka pakaru hei paura i te wā e kawehia ana, ka huri rānei hei pungarehu ina tomo ki te tauhohenga—he aha te whakakorikori ka taea e ia te whakatutuki?AruminaI muri i te whakapūtanga me te whakapūtanga, ka whanake te kaha o ngā tautoko hei tu atu i ēnei "mamaetanga", ka whakarite kia roa te mahi a te taputapu tauhohenga, kia pumau hoki. Koinei te tikanga o ngā kaimahi mātau ina kī rātou "he totoka tēnei whakakorikori."
Hei tāpiritanga, he tino pakari hoki—he tino kaha te āhua o ōna mata.
Kāore te mata o te alumina i te maeneene. Kei roto ngā pae waikawa, ngā pae taketake rānei. Kei ēnei pae tonu ngā kaha whakatere mō ētahi tauhohenga. Ko te mea nui ake, ka taea e rātou te "tauhohe" ki te konganuku hohe e tautokona ana—he āhuatanga e kiia nei e tātou he tauhohenga.
He maha ngā painga o tēnei taunekeneke. I tētahi taha, he rite tana mahi ki te "piripiri", e "piri" ana i ngā matūriki whakarewa ki te tautoko, e ārai ana i a rātou kia kaua e neke, e kohikohi, e tipu rānei i ngā pāmahana teitei (e kiia ana tēnei ko te sintering). Kia puta te sintering, ka tino heke te mahi catalytic. I tētahi atu taha, ka taea e ia te whakarerekē i te āhua hiko o ngā matūriki whakarewa, kia pai ake ai tā rātou mahi i roto i ngā tauhohenga catalytic, ka tutuki ai he pānga synergistic o te "1+1>2".
Ae, kāore he mea e tino tika ana. Kāore hoki ngā tautoko Alumina e kore he hapa. Hei tauira, i roto i ngā taiao tino pāmahana teitei me te kohu wai, ka pā pea ki tētahi "whakawhitinga āhuahanga," ka huri mai i te momo γ tino kaha ki te momo α iti ake te kaha, ka arahi ki te hinga o te hanganga pore me te whakaheke tere i te horahanga o te mata. He rite tēnei ki te waro whakahohe e tahuna ana ki roto i te karāpeti; ahakoa he waro tonu, he tino rerekē tōna kaha mimiti. Nō reira, kua mahi ngā kairangahau ki te whakapai ake i tōna pumau wera mā te tāpiri atu ki ētahi atu huānga (pēnei i te silicon me te zirconium) me te whakawhanake rānei i ngā tukanga whakarite hou hei whakanui ake i ōna kaha me te whakaiti i ōna ngoikoretanga.
Nō reira, kei roto i tēnei paura mā noa te nui o te mātauranga. Ehara i te mea he hangarau pango e kore e taea te rapu, engari ko tēnei momo rauemi tonu, e whai ana kia taurite me te whakapai ake i ngā taipitopito katoa, e tautoko ana i te haurua o te pūnaha whakatere ahumahi hou. Mai i te purenga o te hauātanga o te motuka ki te pakaru me te whakahou i te hinu, me te hanga i ngā rauemi mata matū, tata tonu te kitea te mahi puku a ngā kaikawe alumina i muri i ngā whakaaturanga.
Kāore e tiaho pērā i ngā konganuku utu nui pērā i te konukawata, te palladium rānei, ā, he iti iho te utu, engari ko tōna pono, tōna roa, me tōna whai huatanga nui e waiho ana hei turanga tino pakari mō ngā tono ahumahi nui. A te wā ka rongo koe i tētahi putanga hou i roto i te hangarau whakatere, me mihi nui ki a ia, nā te mea ko te paura alumina, te toa ngaro i muri i ngā whakaaturanga, e tika ana kia nui te mihi ki a ia mō tēnei whakatutukitanga.
