ʻO ke kilokilo o ka pauka ʻokikene alumini: Pehea e hoʻololi ai i nā waiwai o nā mea
Manaʻo paha ʻoe ʻo ka huaʻōlelo "ʻokikene alumini"He ʻano hoʻonaʻauao a mamao loa ia mai ke ola o kēlā me kēia lā. Akā e ʻae mai iaʻu e haʻi aku i kahi mea āu e ʻike ai—pepa one. ʻAe, ʻo ia pepa ʻāwiliwili i loko o kāu pahu mea hana i hoʻohana ʻia no ka hoʻomaʻemaʻe ʻana i nā ʻaoʻao lāʻau a me nā metala. Ua noʻonoʻo paha ʻoe no ke aha i loaʻa ai i kēlā pepa ka hiki ke kupaianaha, hiki ke hoʻomaʻemaʻe i nā ʻili paʻakikī? ʻO ka mea huna pinepine i loko o nā ʻāpana liʻiliʻi ma kona ʻili, a ʻoi aku ka pinepine ma mua o ka ʻole, ʻo ka hōkū o kēlā mau ʻāpana ka pauka alumini oxide.
I ka nānā mua ʻana, ʻike ʻia he pauka keʻokeʻo maʻamau wale nō—e kānana i kahi lima ma kou mau manamana lima, a ua like ia me ka palaoa. Akā, mai hoʻowahāwahā iā ia. Iā mākou he poʻe ʻepekema mea, ʻaʻohe mea ʻē aʻe o kēia mea mai kahi pauka kilokilo i hiki ke hoʻololi i ka pōhaku i ke gula. I kēia lā, e wehewehe wau pehea e hana ai ka pauka alumini oxide i kāna hana kilokilo, e hoʻololi mālie ana i nā ʻano o nā mea a puni mākou.
I. Ke Kumu o Kona Mana Kilokilo: He ʻAno Paʻakikī a me nā ʻAno Versatile
ʻO ke kilokilo opauka aluminaʻO kona ʻano maoli ka aluminiuma trioxide, ka mea e paʻa ana i ka wahi ʻeiwa ma ka pae paʻakikī mineral, ʻoi aku ka nui ma mua o ke daimana a me kekahi mau mea 'superhard' ʻē aʻe. E noʻonoʻo i kēia: ma waena o nā mea maʻamau, ke kila, ke keleawe, a me ka alumini - ʻaʻole i palupalu ma mua o ia? ʻO ke ʻano kēia, i ka wā e kū ai me ka hapa nui o nā metala, nā keramika, a i ʻole nā polymer, hana ia e like me ke 'kanaka paʻakikī', e paʻa ana i ka 'mana' piha.
Akā, ʻaʻole kēia kona ʻano kupaianaha loa. ʻO ka mea kupanaha maoli, aia i ko mākou hiki ke hoʻohālike i kēia 'kanaka paʻakikī' ma o nā kaʻina hana like ʻole i nā ʻano a me nā nui like ʻole - mai kahi "koa" paʻakikī a i kahi 'mea pena kiʻi' akahai, ʻoi aku ka maikaʻi ma kēlā me kēia kūlana.
Ma ke ʻano he 'Koa': I nā hana one a me ka wili ʻana,pauka ʻokikene aluminiua hoʻokumu ʻia i loko o nā micro-particles ʻoi. Ma lalo o ke kaomi kiʻekiʻe, hoʻouka kēia mau ʻāpana e like me ka pūʻali koa e kūʻē i nā ʻili o ka workpiece. Ma o ka ʻoki microscopic a me ka hopena, wehe pono lākou i ka lepo a me nā burrs, a hana paha i kahi substrate roughened kūpono no nā uhi ma hope. ʻŌlelo pinepine wau i kaʻu mau haumāna: 'E ʻike pehea e hoʻomaʻemaʻe ai kāna hoʻouka kaua i ka "maka" o ka mea a hōʻike i kona "iwi"?'
I ka hana ʻana ma ke ʻano he "mea pena kiʻi": Ke wili ʻia a lilo i pauka micron a nanometer paha, loli kona kuleana. I kēia manawa, ʻaʻole ia e "luku" akā "kūkulu". Hoʻohui ʻia i loko o nā plastik, laholio, a i ʻole nā mea keramika, hoʻonui nui ia i ka paʻakikī, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa wela o kēia mau mea kumu. E like me ka hoʻohui ʻana i ka hoʻoikaika kila i ka sima, hoʻopiha koke ia i ka mea i palupalu a palupalu paha me ka pono o ke kūkulu ʻana.
II. Ke Wehe ʻia nei ka Mana: Ke ʻIke nei i kāna Hana ma ka Hana
He mea makepono ke kamaʻilio; e ʻae mai iaʻu e kaʻana like i kekahi mau hiʻohiʻona i ʻike maka ʻia.
Haʻawina Hihia ʻEkahi: Palekana Palakiko
ʻO kekahi o kā mākou mea kūʻai aku he loea i nā kia kiʻekiʻe. Ma mua, ua hoʻohana lākou i nā plastics ʻenekinia maʻamau, kahi i hōʻoia ʻia ʻaʻole lawa i ke kūpaʻa ʻana i ka ʻaʻahu—e hōʻike ana i ka ʻaʻahu nui i loko o nā mahina a hoʻoulu i ka walaʻau nui. Ua hoʻāʻo kā lākou mau ʻenekinia i nā hoʻonā like ʻole, a pau me nā hopena hoʻohoka. A laila ua manaʻo mākou e hoʻohui like i kahi hapa kikoʻī o ka micron-gradepauka ʻokikene aluminii loko o kā lākou mea maka. Ua koke ka hopena! Ua hōʻike nā kia hopena i nā piʻi he nui i ke ola o ka ʻaʻahu a ua hana maʻalahi a mālie hoʻi. No ke aha mai? No ka mea, ʻo kēlā mau ʻāpana alumini oxide i ʻike ʻole ʻia i hoʻokomo like ʻia ma waena o nā molekole plastik i hoʻokumu i kahi pūnaewele kākoʻo ikaika loa. I ka wā i hui pū ʻia ai nā kia a me ka friction, ʻo ia mau ʻāpana alumini oxide paʻakikī i hāpai i nā ikaika frictional mua, e pale ana i ka plastic ponoʻī. Ua like ia me ke kau ʻana i kahi papa o nā ʻiliʻili paʻakikī ma luna o nā alanui lepo palupalu - hoʻololi koke ka hiki ke lawe i ka ukana.
Hihia ʻElua: Ke hana ʻana i nā uhi "hiki ʻole ke luku ʻia"
E noʻonoʻo i nā hoʻopau lāʻau kiʻekiʻe a i ʻole nā papa papahele ʻoihana - no ke aha lākou e kūpaʻa ai i ka ʻaʻahu a me nā ʻōpala? ʻO ka pinepine, aia ka mea huna i ka pauka alumini oxide. Ke hoʻohui ʻia i ka varnish moakaka, e noho keʻokeʻo ia akā, ke wili maikaʻi ʻia, he liʻiliʻi ka hopena o ke kala me ka hoʻonui nui ʻana i ka paʻakikī o ka uhi a me ke kūpaʻa ʻana i ke ʻōpala. ʻOiai hiki i kahi kī ke waiho i kahi ʻōpala ʻokoʻa ma ka pena maʻamau, ma nā ʻili i hoʻonui ʻia i ka alumini oxide hiki ke hana wale i kahi māka palupalu a maʻalahi hoʻi e wehe. Ua like kēia hopena me ke kau ʻana i nā 'pale microscopic' he nui ʻole i loko o ka uhi.
Haʻawina Hihia ʻEkolu: Ke Hana ʻana i nā 'Pale Kaua Pale Ahi'
He kūpaʻa loa ka aluminiuma oxide i ka wela, me kahi kiko heheʻe e ʻoi aku ana ma mua o 2,000 degere Celsius. Ke hoʻohana nei i kēia waiwai, hiki ke hana ʻia i loko o nā ʻano porous e like me ka huʻa a i ʻole nā hale fibrous, e hana ana i nā mea hoʻomehana wela kiʻekiʻe. Hilinaʻi nā tile pale wela mokulele a me nā uhi umu wela kiʻekiʻe ma luna o ia mea. Hana ia ma ke ʻano he pale, e pale paʻa ana i ka wela weliweli e pale i nā lako a i ʻole nā hale i loko. Hōʻike kēia i ka hui hope loa o kona ʻano 'kanaka paʻakikī' a me ke kūpaʻa wela.
III. Ke Kumukūʻai o ke Kilokilo a me ke Akamai o ke Kaulike
ʻOiaʻiʻo, ʻaʻole pono e hoʻohana pono ʻia ke kilokilo; koi ia i ka manaʻo o ke kaulike. ʻAʻole ʻoi aku ka maikaʻi o ka nui. E noʻonoʻo i kēia: ʻo ka hoʻohui ʻana i ka pauka alumina nui i ka laholio e hoʻopaʻakikī paha iā ia a hoʻonui i ke kūpaʻa ʻana i ka ʻaʻahu, akā e mōhai ia i ka elasticity a me ka maʻalahi, e hoʻolilo iā ia i mea palupalu, e like me ka piliki e hiki ke haki. He hihia ia o ka hana nui ʻana.
No laila, hoʻohana mākou he poʻe ʻepekema mea i ko mākou mau lā e hoʻomaʻemaʻe ana i kēia mau 'hoʻohālikelike' a me nā 'kaʻina hana.' Pehea ka nui o ka ʻāpana o kapauka aluminae? He aha ka lakio hoʻohui kūpono? Pehea e hiki ai iā mākou ke hōʻoia i ka hoʻopuehu like ʻana ma o ka mea ma mua o ka hui pū ʻana? He hohonu ka ʻepekema ma hope o kēia, e koi ana i ka hoʻokolohua nui a me ka ʻike i hōʻiliʻili ʻia. I kekahi manawa, ʻo ka ʻokoʻa hoʻokahi pakeneka wale nō i ka nui o ka lāʻau e hiki ai ke hopena i kahi honua o ka ʻokoʻa i ka hana o ka huahana hope loa.
No laila, ʻike ʻoe, ʻo kēia lima pauka keʻokeʻo maʻamau i hoʻopiha ʻia me ke kilokilo kupaianaha. E like me kahi jack-of-all trades versatile, ma o nā ʻano hana like ʻole a me nā hui pū ʻana, hiki iā ia ke hoʻololi i nā mea maʻamau ma mua o ka ʻike ʻia. Mai ka pena papahele ma lalo o ko mākou mau wāwae a hiki i nā ʻāpana mokulele e lele ana ma ka lewa, aia kona alo ma nā wahi āpau.
Hoʻomanaʻo mālie mai ia iā kākou ʻaʻole ʻike ke aupuni o nā mea i nā lula paʻa. Ma o ka hoʻohui akamai a me ka hui ʻana, hiki i ka nāwaliwali ke lilo i mea ikaika, hiki i ka palupalu ke paʻakikī, a hiki ke hoʻololi ʻia ka mea maʻamau i mea kupaianaha. ʻO kēia ke kilokilo o ka pauka alumini oxide, a me ke ʻano maoli o ka mea e hoʻohiwahiwa ai i ka ʻepekema mea. I ka manawa aʻe e hoʻohana ai ʻoe i kahi pepa one a i ʻole e hoʻopā i kahi panela composite me kahi ʻano kupaianaha, e ʻakaʻaka wale paha ʻoe iā ʻoe iho, e hoʻomanaʻo ana i loko o ia mea, hiki i nā sprites alumini oxide liʻiliʻi he nui ʻole ke hana mālie.
