ʻO ke kuleana kipi o ka pauka alumina i ka ʻoihana abrasive
ʻIke ka poʻe i hana ma nā hale hana abrasive he mea ʻeha ke poʻo ke hana me nā mea paʻakikī kiʻekiʻe - nā huna ahi mai ka huila wili, nā ʻōpala ma ka wahi hana, a me ka emi ʻana o ka nui o ka hua. ʻOi aku ka ʻeleʻele o ka maka o ka luna ma mua o ka lalo o ka ipuhao. A hiki i ka pauka keʻokeʻo opauka aluminaua holo wikiwiki i loko o ke kahua kaua, ua huki ia i ka ʻoihana abrasive i loko o kahi au hou. I kēia lā, e kamaʻilio kākou e pili ana i ke kumu i lilo ai kēia mea i "mea hoʻōla wili" o ka ʻoihana hou!
1. Talena: "koa hexagonal" i ka ʻoihana abrasive
Ua hānau ʻia ka pauka Alumina e lilo i kanaka paʻakikī e ʻai ana i kēia kīʻaha laiki. ʻEkolu mau waiwai paʻakikī e hoʻopau pololei i kona mau hoa:
Kiʻekiʻe ka paʻakikī: Hoʻomaka ka paʻakikī Mohs ma 9.0, ʻo ka lua wale nō ma hope o ke daimana. Ua ana ʻia e kahi hale hana mea hana ma Guangdong: I ka ʻoki ʻana i ke kila wikiwiki, ʻekolu manawa ke ola o nā huila wili alumina ma mua o nā mea abrasive maʻamau. Ua ʻōlelo ʻo Huang, ka haku kahiko, me kahi cigarette i loko o kona waha: "Ua hoʻololi au i ka huila wili i ʻekolu manawa i ka ʻoki ʻana i ke kila alloy, akā i kēia manawa hiki iaʻu ke hana a pau me ka ʻole o ka hanu ʻana!"
Maʻemaʻe kupaianaha: 99.6% ka nui o ka α-Al₂O₃, ua kāohi ʻia nā haumia hao ma lalo o 0.01%. Ua pohō ka Hale Hana Semiconductor Shanghai: me ka hoʻohana ʻana i nā mea abrasives i loaʻa ka hao e hoʻopili ai i nā wafers, ua like ka ʻili me nā pockmarks ma hope o ʻekolu mahina; me ka hoʻohana ʻana i ka pauka alumina e mālama ai, ʻaʻole ia e loli ke kala ʻoiai i loko o nā ʻauʻau waikawa.
Ua like ke kūpaʻa wela me kahi ʻīlio kahiko: he 2050℃ ka pae heheʻe, a he haʻahaʻa ka coefficient hoʻonui wela e like me 4.8 × 10⁻⁶/℃. Hoʻohana kahi hale hana nozzle rocket ma Qingdao iā ia e wili i nā mea hoʻohuihui wela kiʻekiʻe, a ʻo ka loli o ka nui ma lalo o 1500℃ kaiapuni he emi ma mua o 6 manawa ke anawaena o ka lauoho.
ʻO ka mea kupaianaha hou aku, hiki iā ia ke hoʻololi i kona ʻano i 72 mau manawa - mai nā ʻāpana pālahalaha pae micron a i ka pauka poepoe pae nano, hiki ke poepoe a pālahalaha paha e like me kou makemake, a ua hoʻolālā kūikawā ʻia e hoʻōla i nā ʻano hoʻolohe ʻole āpau!
2. Ke kahua kipi: "Hana pae pahū nukelea" ma nā kahua kaua nui ʻekolu
Hale hana Semiconductor: Nā mākau humuhumu pae Nano
Ka hoʻowali ʻana i ka wafer silicon: Holo ka micropowder alumina pālahalaha ma luna o ka ʻili o ka wafer silicon e like me ka heʻe hau, a emi ka nui o ke kahakaha ʻana ma ka 70% ma ka wili paheʻe ma kahi o ka ʻōwili kuʻuna. Ua ʻōlelo ka haku o SMIC: "ʻOi aku ka palupalu o kēia hana ma mua o ka humuhumu!"
ʻĀpana kalapona silikona: ʻEli ka wai hoʻowali nano-alumina i loko o ka hakahaka ʻāpana, a hoʻomaikaʻi ʻia ka pono o ka hoʻopuehu wela e ka hopena tunnel quantum, a piʻi ka nui o ka hua i 99.98%. Ua paʻi ka ʻenekinia papahana i ke kiʻi microscope electron a haʻaheo: "He kiʻekiʻe loa kēia pololei a hiki i kahi makika e kū ana ma luna e pono e māhele!"
ʻO ka substrate sapphire: Hoʻopili ka alumina submicron i ka substrate LED i Ra<0.3nm, ʻoi aku ka laumania ma mua o ke aniani. Ua ʻōlelo hauʻoli ke poʻo o ka hale hana o Dongguan Optoelectronics: "I kēia manawa ke hana nei mākou i nā aniani iPhone, a ʻaʻole hiki i nā mea nānā Apple ke ʻike i ka hewa me lākou!"
Hale hana kaʻa: mea pepehi kālā ma ka pūnaewele
Aerospace: nā loea paʻakikī koʻikoʻi
Ka hana ʻana i ka mortise a me ka tenon o ka pahi turbine:Huila wili aluminaHana ia ma ka nickel-based alloy, a hiki iā ia ke kū i 100 mau hola me ka ʻole o ka nalowale ʻana o ka pauka ma ka wikiwiki o 2200 rpm. Nānā akula ka mea hoʻokele hoʻāʻo ʻo Lao Li i ka pale nānā a hoʻōho akula: "Me kēia pale ʻana i ke komo ʻana, pono ʻo Musk e hoʻokuʻu i nā cigarette!"
ʻO ka hoʻopili ʻana i ka paia o loko o ka nozzle rocket: Hoʻemi ka pauka alumina i uhi ʻia me ka nano i ka ʻoʻoleʻa i Ra0.01μm, a hoʻomaikaʻi ʻia ka pono o ka wahie e 8%. Ua ʻōlelo ke ʻenekinia nui me nā maka ʻulaʻula: "Hiki i kēia mea hoʻokahi wale nō ke mālama i ʻekolu tona o ka wahie i kēlā me kēia makahiki!"
3. Hoʻouka kū'ē i ka hana kūloko: mai ka "ʻāʻī paʻa" a i ka "hakakā lima"
ʻO nā mea hoʻoheheʻe alumina kūloko he "moʻolelo kaumaha" - ke kūpaʻa ʻole o ka ʻaʻahu, nā ʻāpana paʻa ʻole, ka hoʻohuihui pauka nano e like me ka sopa pimple, a ua hoʻopaʻa ʻia ka mākeke kiʻekiʻe e nā hui ʻAmelika a me Kepani13. Akā ʻo ka nalu o ka localization semiconductor i koi i kahi counterattack Jedi:
Hoʻouka maʻemaʻe: Ua hoʻomohala kahi hale hana ma Luoyang i kahi kaohi mahana akamai o ka umu arc, a ua hōʻea ka helu hoʻololi pae α i 99.95%, a ua like ka maʻemaʻe me Showa Denko o Iapana.
ʻO ka metaphysics o ka nui o nā ʻāpana: Hoʻohana nā ʻoihana Zhejiang i nā mea hoʻokaʻawale turbine AI e kāohi i ka hoʻolaha ʻana o ka nui o nā ʻāpana i loko o ± 0.1μm. Ua hāʻule nā mea kūʻai aku Korea i ko lākou mau ʻāwae i ka nānā ʻana i nā waiwai: "ʻOi aku ka pololei o kēia ʻikepili ma mua o ka mea ʻike!"
Ka hānau hou ʻana o nā ʻōpala: Hoʻopau a hoʻomaʻemaʻe hou ke kahua Shandong i nā ʻōpalanā huila wili, a ua hoʻemi ʻia ka lakio hoʻohuihui i 30%, a ua hoʻemi ʻia ke kumukūʻai e 40%. Ua ʻakaʻaka a hoʻohewa ke alakaʻi o ka hale hana, ʻo Lao Zhou: "ʻO ka ʻōpala i hoʻolei ʻia me ka pohō i kēia manawa ua ʻoi aku ka waiwai ma mua o nā mea hou!"
4. Ke kahua kaua o ka wā e hiki mai ana: ʻekolu mau ʻano nui i paʻa
Kaohi pae Nano: Ua hoʻomohala ka hale hana ʻo Hefei i ka ʻenehana ʻeleʻele - ʻenehana waiho papa atomika e kau i ka "pale kaua" ma luna o nā pauka liʻiliʻi a hoʻoponopono i ka pilikia o ka hoʻopili ʻana. Ua hāpai ka mea noiʻi i ka laʻana a haʻaheo: "I kēia manawa, ʻoi aku ka maʻalahi o ka poli ʻana o nā ʻāpana ma mua o ka waxing!"
ʻŌmaʻomaʻo Hoʻokahuli Aupuni: Hoʻohana ka hale hana ʻo Chongqing i kahi ʻōnaehana hoʻōla waikawa ʻōpala e hōʻemi i ka hoʻokuʻu ʻana o 300 tone o nā ʻōpala weliweli i kēlā me kēia makahiki. Ua kipa mai ka poʻe mai ka Environmental Protection Bureau a hāʻawi i kahi manamana nui: "E hoʻokuʻu ʻoe i ka hale hana mālama wai ʻino!"
Nā mea hana wili akamai: Ua hoʻokomo kahi hale hana ma Zhengzhou i kahi mea ʻike kaomi ma ka huila wili e hoʻoponopono i nā palena wili i ka manawa maoli. Ua paʻi ʻo Xiao Liu, he loea i hānau ʻia i nā makahiki 1990, ma ka papa keyboard a haʻaheo: "I kēia manawa ua maʻalahi ka hoʻoponopono ʻana i nā palena ma mua o ka pāʻani ʻana i nā pāʻani, a ua hiki ka helu hua i 99.8%!"
