ʻO ka hana kipi o ka pauka alumina i ka ʻoihana abrasive
ʻO ka poʻe i hana i loko o nā hale hana abrasive, ʻike lākou he poʻo poʻo ka hana ʻana i nā mea paʻakikī kiʻekiʻe - nā ʻulaʻula mai ka huila wili, nā ʻōpala ma ka workplece, a me ka hāʻule ʻana o ka helu hua. ʻOi aku ka ʻeleʻele o ka maka o ka luna ma mua o ka lalo o ka ipuhao. A hiki i ka pauda keokeo oalumina paukaholo wikiwiki i ke kahua kaua, ua kauo ia i ka ʻoihana abrasive i kahi au hou. I kēia lā, e kamaʻilio e pili ana i ke kumu i lilo ai kēia mea i "hoola wili" o ka ʻoihana hou!
1. Talented: "hexagonal warrior" ma ka ʻoihana abrasive
Hānau ʻia ka pauka alumina he kanaka paʻakikī e ʻai i kēia kīʻaha laiki. ʻEkolu mau waiwai paʻakikī e hōʻeha pololei i kona mau hoa:
He kiʻekiʻe ka paʻakikī: Hoʻomaka ka paʻakikī Mohs ma 9.0, ʻelua wale nō i ke daimana. Ua ana ʻia kahi hale hana mea hana ma Guangdong: I ka wā e ʻoki ai i ke kila kiʻekiʻe, ʻo ke ola o nā huila alumina wili he 3 mau manawa ma mua o nā abrasives maʻamau. Ua ʻōlelo ka haku kahiko ʻo Huang me kahi paka ma kona waha: “Ua hoʻololi au i ka huila wili i ʻekolu manawa i ka wā e ʻoki ai i ke kila kila, akā i kēia manawa hiki iaʻu ke hana i ke ala āpau me ka ʻole o ka hanu!"
Maʻemaʻe kupaianaha: 99.6% α-Al₂O₃ maʻiʻo, hoʻopau ʻia nā mea haumia hao ma lalo o 0.01%. Ua pilikia ka hale hana Semiconductor o Shanghai: me ka hoʻohana ʻana i nā mea hao i loko o ka hao e hoʻomaʻemaʻe i nā wafers, ua like ka ʻili me he pockmarks ma hope o ʻekolu mahina; me ka hoʻohana ʻana i ka pauka alumina e mālama ai, ʻaʻole ia e hoʻololi i ka waihoʻoluʻu i loko o ka ʻauʻau waika.
ʻO ke kūpaʻa wela e like me ka ʻīlio kahiko: ka helu heheʻe 2050 ℃, ka helu hoʻonui wela ma lalo o 4.8 × 10⁻⁶/℃. Hoʻohana ʻia e kahi hale hana nozzle rocket ma Qingdao e wili i nā alloys wela kiʻekiʻe, a ʻo ka nui o ka fluctuation ma lalo o 1500 ℃ ʻoi aku ka liʻiliʻi ma mua o 6 mau manawa ke anawaena o ka lauoho.
ʻO ka mea kupaianaha, hiki iā ia ke hoʻololi i kona ʻano he 72 mau manawa - mai ka micron-level flat particles a hiki i ka nano-level spherical powder, hiki ke poepoe a pālahalaha paha e like me kou makemake, a ua hoʻolālā kūikawā ʻia e hoʻōla i nā ʻano hoʻolohe ʻole!
2. Hōʻike kipi: "Nuclear explosion-level performance" ma nā kahua kaua nui ʻekolu
Hale Hana Semiconductor: Nā mākau hana humuhumu Nano-level
ʻO ka ʻōniʻoniʻo silikoni: ʻO ka micropowder alumina palahalaha ma luna o ka ʻili o ka wafer silika e like me ka holo ʻana, a hāʻule ka nui o ka ʻōpala ma 70% ma ka wili ʻana ma mua o ka ʻōwili kuʻuna. Ua hoʻōho ka haku o SMIC: "Ua ʻoi aku ka maʻalahi o kēia hana ma mua o ka hana ʻana!"
Silicon carbide chip: Nano-alumina polishing wai drills i loko o ka puʻupuʻu puʻupuʻu, a hoʻomaikaʻi ʻia ka maikaʻi o ka hoʻopau ʻana i ka wela e ka hopena quantum tunnel, a piʻi ka nui o ka hua i 99.98%. 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 ona e hana ʻia!"
Sapphire Subs Ua ʻōlelo ʻo ka luna o Dongguan Optoelectronics Factory me ka hauʻoli: "I kēia manawa ke hana nei mākou i nā lens iPhone, a ʻaʻole hiki i nā mea nānā Apple ke ʻimi hewa iā lākou!"
Hale hana kaʻa: hoʻopau uku ma ka pūnaewele
Aerospace: ʻoihana hoʻokūkū koʻikoʻi
ʻO ka hoʻoheheʻe ʻana o ka ʻūhā turbine mortise a me ka hana ʻana:huila wili aluminahana ma ka nickel-based alloy, a hiki iā ia ke kū i nā hola 100 me ka nalowale ʻole o ka pauka ma ka wikiwiki o 2200 rpm. Ua nānā ka mea hoʻokele hoʻāʻo ʻo Lao Li i ka pale kiaʻi a hoʻōho: "Me kēia ʻaʻahu kūʻē, ʻo Musk hoʻi e hele i ka paka!"
Rocket nozzle i loko o ka paia polishing: Nano-coated alumina pauka e hoemi i ka roughness i Ra0.01μm, a me ka wahie e hoʻomaikaʻi 'ia e 8%. Ua ʻōlelo ka ʻenekinia nui me nā maka ʻulaʻula: "ʻO kēia mea hoʻokahi wale nō e hiki ke mālama i ʻekolu tona wahie i kēlā me kēia makahiki!"
3. Ka hoʻouka kaua ʻana o ka hana hale: mai ka "ʻā'ī paʻa" a i ka "hakakā lima"
He "moʻolelo kaumaha" nā alumina alumina i hoʻohana ʻia - ʻaʻohe pale ʻana i ka ʻaʻahu, nā pūʻulu paʻa ʻole, ka hoʻohuihui ʻana i ka pauka nano e like me ka soup pimple, a ua monopoli ʻia ka mākeke kiʻekiʻe e nā hui ʻAmelika a me Iapana13. Akā ʻo ka nalu o ka semiconductor localization i koi aku i kahi counterattack Jedi:
Hoʻouka maʻemaʻe: Ua hoʻomohala kahi hale hana ma Luoyang i kahi hoʻokele wela naʻauao arc, a ua hōʻea ka helu α phase hoʻololi i 99.95%, a ua like ka maʻemaʻe me Showa Denko o Iapana.
Hoʻohana nā hui ʻo Zhejiang i nā mea hoʻohālikelike AI turbine e hoʻomalu i ka hāʻawi ʻana i ka nui o nā ʻāpana i loko o ± 0.1μm. Ua hāʻule nā mea kūʻai Korea i ko lākou mau ʻāwae i ka nānā ʻana i nā waiwai: "Ua ʻoi aku ka pololei o kēia ʻikepili ma mua o ka mea ʻike!"
ʻO ka hānau hou ʻana o ka ʻōpala: Hoʻopau ke kumu ʻo Shandong a hoʻomaʻemaʻe hou i ka ʻōpalawili huila, a ua ho'ēmiʻia ka ratio admixture i 30%, a ua ho'ēmiʻia ke kumukūʻai e 40%. Ua ʻakaʻaka ʻo Lao Zhou ke alakaʻi o ka hale hana: "Ua ʻoi aku ka waiwai o ka ʻōpala i hoʻolei ʻia ma mua ma mua o nā mea hou!"
4. ʻO ke kahua kaua e hiki mai ana: ʻekolu mau ʻano nui i paʻa
Nano-level control: Hefei laboratory ua hele mai me ka ʻenehana ʻeleʻele - ʻenehana deposition layer atomic e kau i ka "mea kaua" ma luna o nā pauka liʻiliʻi a hoʻonā i ka pilikia o ka agglomeration. Ua hoʻopaʻa ka mea noiʻi i ka laʻana a haʻaheo: "I kēia manawa ua ʻoi aku ka maʻalahi o ka puliki ʻana ma mua o ka waxing!"
Green Revolution: Ke hoʻohana nei ka mea kanu ʻo Chongqing i kahi ʻōnaehana hoʻihoʻi ʻana i ka waika e hōʻemi i ka hoʻokuʻu ʻia ʻana o 300 tons o ka ʻōpala pōʻino i kēlā me kēia makahiki. Hele mai ka poʻe mai ka Environmental Protection Bureau e kipa a hāʻawi i ka manamana lima: "E waiho ana ʻoe i ka hale hoʻoheheʻe wai!"
Nā mea hana wili akamai: Ua hoʻokomo kahi hale hana ma Zhengzhou i kahi sensor kaomi ma ka huila wili e hoʻoponopono i nā ʻāpana wili i ka manawa maoli. Ua kākau ʻo Xiao Liu, kahi ʻenehana i hānau ʻia i ka makahiki 1990, ma ka papa keyboard a haʻaheo: "I kēia manawa ʻoi aku ka maʻalahi o ka hoʻoponopono ʻana i nā ʻāpana ma mua o ka pāʻani ʻana i nā pāʻani, a ua hiki i ka 99.8% ka hopena!"
