ʻO ka mea huna o ka pauka carbide silicon ʻōmaʻomaʻo e hoʻomaikaʻi i ka hana o nā mea i hui pū ʻia

ʻIke ka poʻe i hana i nā mea i hui pū ʻia he ʻoi aku ka paʻakikī o ka hoʻohui ʻana i nā pono o nā mea like ʻole i loko o kahi kīʻaha maikaʻi ma mua o ka hoʻoponopono ʻana i ka pilina ma waena o ka makuahōnōwai wahine a me ka hūnōna wahine. Akā, mai ka wā i puka mai ai ʻopauka carbide silicon ʻōmaʻomaʻo, ka "mea hoʻonani kilokilo", ua huli pololei ka pōʻai mea hui i ke "ʻano wehe". I kēia lā, e wehe kākou i kēia pale pohihihi a ʻike pehea e hiki ai i kēia puʻu pauka ʻōmaʻomaʻo ke hoʻolohe i nā haku haʻaheo e like me ke kalapona kalapona a me nā keramika.

1. ʻO ke koa hexagonal akamai

Ua hānau ʻia ka pauka silicon carbide ʻōmaʻomaʻo e lilo i "pauka moeʻuhane" o nā mea i hui pū ʻia. ʻO ka paʻakikī Mohs he 9.5, ʻoi aku ka ʻino ma mua o ka daimana. Ua hana kahi hale hana paleki ma Guangdong i kahi hoʻohālikelike. ʻO ka mea i hui pū ʻia me 20% silicon carbide ʻōmaʻomaʻo he index pale ʻaʻahu he 3 mau manawa o nā mea kuʻuna. Ua hoʻopā ke alakaʻi o ka hale hana ʻo Lao Huang i ka laʻana a ʻōhumu: "Me kēia paʻakikī, ʻaʻole hiki iā ʻoe ke waiho i kahi māka ma hope o ka hamo ʻana me ka pepa one no ka hapalua hola!"

ʻOi aku ka ʻoi aku ka weliweli o ka conductivity thermal. Ua ana ʻo Shandong Research Institute i ka ʻikepili a ua ʻike ʻia ua piʻi aʻe ka conductivity thermal o nā mea composite alumini-based i loaʻa ka 15% silicon carbide ʻōmaʻomaʻo i 220W/(m·K), ʻo ia hoʻi he 30% ikaika ma mua o ka alumini maʻemaʻe. Ua haka pono ʻo Technician Xiao Liu i ka mea hana kiʻi thermal a kāhea akula: "Ua like kēia pono o ka hoʻokuʻu ʻana i ka wela me ke kau ʻana i kahi ʻōnaehana hoʻoluʻu wai ma ka CPU!"

ʻOi aku ka ʻokoʻa o ke kūpaʻa kemika. I kahi hoʻāʻo ʻana i ka mea uhi o kahi paipu kemika ma Ningbo, ua hoʻomohu ʻia ka mea hui silicon carbide ʻōmaʻomaʻo i loko o ka waikawa sulfuric i hoʻohui ʻia no ka hapalua makahiki, a ʻo ka helu pohō kaumaha ma lalo o 0.3%. Ua paʻa ka luna nānā maikaʻi ʻo Lao Wang i ka laʻana a haʻaheo: "ʻO kēia kūpaʻa i ka pala, ʻoiai ʻo ka umu alchemy a Taishang Laojun e pono e hala i kahi cigarette!"

2. ʻO ka "manawa kilokilo" o ke kaʻina hana hui

Ua maikaʻi loa ka ʻenehana hoʻopuehu i kēia manawa. Ua hana kahi hui ma Jiangsu i ka hui pū ʻana o ka "ultrasound + ball milling", ka mea e hoʻopuehu like i ka micropowder ma mua o nā momi i loko o ke kī waiū. Ua hāpai ʻo Master Lao Li i ke kiʻi o ka microscope electron a haʻaheo: "E nānā i kēia nui o ka hoʻolaha ʻana, e nalowale nā ​​​​ʻanuʻu inā piʻi lākou i luna!"

ʻOi aku ka ikaika o ka ʻenehana ʻeleʻele o ka hui pū ʻana o ka interface. Ua hoʻonui ka mea nano-coupling i hoʻomohala ʻia e kahi keʻena hoʻokolohua ma Shanghai i ka ikaika o ka hoʻopaʻa ʻana ma waena o ka micropowder a me ka matrix i 150MPa. Ua hāpai ke alakaʻi papahana i kāna mau aniani a ʻōlelo akula: "ʻO ka manawa hope loa a mākou i hana ai i ka hoʻāʻo shear, ua hoʻololi ʻia ke fixture, akā ʻaʻole i hoʻokaʻawale ʻia ka mea i hui pū ʻia!"

3. "Hiʻohiʻona hoʻomālamalama" o ka hoʻāʻo hakakā maoli

Ua pupule ka ʻoihana mokulele no ka manawa lōʻihi. Hoʻohana nā ʻōpuʻu turbine o kahi hale hana mīkini mokulele ma Chengducarbide silicon ʻōmaʻomaʻoe hoʻoikaika i nā mea i hoʻohui ʻia i ka seramika, a ʻo ke kūpaʻa o ka mahana a hiki i 1600 ℃. Nānā ka mea hoʻokele hoʻāʻo ʻo Lao Zhang i ka dashboard a kahe ka wai: "Me kēia hana, pono nā ʻenekini jet e kāhea iā Daddy!"

ʻOi aku ka hoihoi o ka bracket pila o nā kaʻa ikehu hou. ʻO ka bracket composite fiber carbon o kahi mea hana ma Ningde he 8 mau manawa ka ikaika o ke kila ma hope o ka hui ʻia ʻana me ka silicon carbide ʻōmaʻomaʻo. I ka wā o ka hoʻāʻo kuʻi ʻana, ua pā ka ʻenekinia palekana ʻo Lao Li i ka puka kaʻa a ʻakaʻaka: "I kēia manawa, ua like kēia kino kaʻa me ke komo ʻana i ʻekolu papa o nā ʻaʻahu pale pōkā!"

He pupule ke kahua o nā poho wela kikowaena 5G. ʻO ka radiator composite alumini o kahi mea hana ma Hangzhou he coefficient hoʻonui wela i kāohi ʻia i 4.8 × 10⁻⁶/℃. Ua kuhikuhi ke alakaʻi loea i ka ʻikepili hoʻāʻo pōʻaiapuni wela a haʻaheo: "Hiki ke hoʻololi ʻia mai -50℃ a i 200℃, a ʻoi aku ka koʻikoʻi o ka loli nui ma mua o Virgo!"

4, "Lōʻihi-manawa" ma ka moʻokāki kumukūʻai

Mai nānā i ke kumukūʻai kiʻekiʻe o ka pākēnekapauka micropoda silicon carbide ʻōmaʻomaʻo, he mea waiwai maoli nō ia ke helu ʻoe i ka huina kālā. Ua hana kahi hale hana mīkini ma Chongqing i kahi helu kālā: ʻoiai ua piʻi ke kumukūʻai o nā mea maka ma 25%, ua hoʻonui ʻia ke ola o ka huahana i ʻehā manawa, a ua lawa ke kumukūʻai mālama i mālama ʻia i loko o ʻekolu mau makahiki e kūkulu i kahi hale hana hou. Ua pā ka wahine kālā i ka helu helu a ʻakaʻaka: "ʻOi aku ka waiwai o kēia ʻoihana ma mua o ka hōʻaiʻē kālā!"

ʻOi aku ka hauʻoli o ka hoʻomaikaʻi ʻana i ka pono hana. Wahi a nā ana maoli o kahi laina hana hana aunoa ma Tianjin, ua hoʻopōkole ʻia ka manawa hoʻōla o nā mea i hui pū ʻia e 40%. Ua haka pono ka luna o ka hale hana i ka pale nui a paʻi i kona mau wāwae: "I kēia manawa ua like ka hiki ke hana me ka holo ʻana i kahi rocket, a ʻaʻole hopohopo nā mea kūʻai aku i ka wā e koi ana i nā kauoha!"

ʻAʻole i kēia manawa he huahana manaʻo ka silicon carbide micropowder ʻōmaʻomaʻo i loko o ka hale hana. Mai nā mokulele e lele ana i ka lewa a hiki i nā kaʻa ikehu hou e holo ana ma ka honua, mai nā ʻāpana kelepona paʻalima e like me ka nui o ka pama a hiki i nā pahi turbine makani 100 mika ka lōʻihi, aia ia ma nā wahi āpau. Ua ʻōlelo ka poʻe loea i ka ʻoihana ua hana kēia mea i lua i ka palena hana o nā mea i hui pū ʻia. I koʻu manaʻo, ʻaʻole kēia he hoʻonui mea maʻalahi wale nō, akā he "pana i ka lima" no ka ʻoihana hou. Inā hoʻomau kēia ʻano, hiki paha i kekahi lā e hoʻohana kā mākou papa ʻoki i kēia ʻenehana ʻeleʻele - ma hope o nā mea a pau, ʻo wai ka mea makemake ʻole i kā lākou mau mea kuke e like me nā mea aerospace?
