ʻO ka mea huna o ka pauka carbide silicon green e hoʻomaikaʻi i ka hana o nā mea hana

ʻO ka poʻe i hana i loko o nā mea i hoʻohuiʻia, uaʻike lākou heʻoi aku ka paʻakikī o ka hoʻohuiʻana i nā mea maikaʻi o nā mea likeʻole i kahi kīʻaha maikaʻi ma mua o ka hoʻohuiʻana i ka pilina ma waena o ka makuahōnōwai wahine a me ka hūnōna wahine. Akā mai ka puka ʻana mai oʻōmaʻomaʻo silikon carbide pauda, ʻo ka "magic seasoning", ua huli pono ka pōʻai mea hoʻohui i ka "mode opening". I kēia lā, e wehe kākou i kēia pale pohihihi a e ʻike pehea e hiki ai i kēia puʻu pauda ʻōmaʻomaʻo ke hoʻolohe i nā haku haʻaheo e like me ke kalapona kalapona a me ka ceramics.

1. ʻO ka "koa hexagonal" makana

Hānau ʻia ka pauka silicon carbide ʻo ia ka "moe pauda" o nā mea hana. ʻO ka paʻakikī Mohs he 9.5, ʻoi aku ka maikaʻi o ka hanu ma mua o ke daimana. Ua hoʻohālikelike kekahi hale hana paʻa ma Guangdong. ʻO ka mea i hui pū ʻia me 20% ʻōmaʻomaʻo silicon carbide he ʻano hōʻailona kūʻē i ka ʻaʻahu he 3 mau manawa ma mua o nā mea kahiko. Ua hoʻopā ʻo Lao Huang ke alakaʻi o ka hale hana i ka laʻana a ʻōlelo ʻo ia: "Me kēia paʻakikī, ʻaʻole hiki iā ʻoe ke waiho i kahi hōʻailona ma hope o ka hamo ʻana me ka pepa one no ka hapalua hola!"

ʻOi aku ka huhū o ka conductivity thermal. Ua ana ʻo Shandong Research Institute i ka ʻikepili a ua ʻike ʻo ka conductivity thermal o nā mea hoʻohui i hoʻokumu ʻia i ka aluminika i loaʻa ka 15% ʻōmaʻomaʻo silicon carbide i 220W/(m·K), ʻo ia ka 30% ʻoi aku ka ikaika ma mua o ka alumini maʻemaʻe. Ua nānā ʻo Technician Xiao Liu i ke kiʻi wela a hoʻōho aʻe: "Ua hoʻohālikelike ʻia kēia hana hoʻopau wela me ka hoʻokomo ʻana i kahi ʻōnaehana hoʻoluʻu wai ma ka CPU!"

ʻOi aku ka ʻokoʻa o ka paʻa kemika. I ka hoʻāʻo ʻana o ka mea hoʻopili o kahi pipeline kemika ma Ningbo, ua hoʻomoʻi ʻia ka ʻōmaʻomaʻo silicon carbide composite material i loko o ka sulfuric acid concentrated no ka hapalua makahiki, a ʻoi aku ka liʻiliʻi o ke kaumaha ma mua o 0.3%. Ua hoʻopaʻa ʻo Lao Wang i ka mea nānā maikaʻi i ka laʻana a haʻaheo: "ʻO kēia kūʻē ʻana i ka corrosion, ʻo ka umu ahi alchemy a Taishang Laojun e hāʻawi i kahi paka!"

2. ʻO ka "manawa kupua" o ke kaʻina hana

Maikaʻi loa ka ʻenehana hoʻopuehu i kēia manawa. Ua hele mai kahi hui ma Jiangsu me ka hui pū ʻana o ka "ultrasound + ball milling", kahi e hoʻopuehu ai i ka micropowder ma mua o nā momi i ka waiū kī. Hapai aʻela ʻo Master Lao Li i ke kiʻi microscope electron a kaena aʻe: “E nānā i kēia puʻupuʻu puʻupuʻu, e nalowale nā ʻanuʻu ke piʻi lākou i luna!”

ʻOi aku ka ikaika o ka ʻenehana ʻeleʻele o ka hui ʻana o ka interface. ʻO ka mea hoʻohui nano-coupling i hoʻomohala ʻia e kahi keʻena hana ma Shanghai ua hoʻonui i ka ikaika paʻa ma waena o ka micropowder a me ka matrix i 150MPa. Ua hoʻokuʻu ke alakaʻi o ka papahana i kāna mau aniani a ʻōlelo ʻo ia: "ʻO ka manawa hope loa mākou i hana ai i ka hoʻāʻo shear, ua deformed ka mea paʻa, akā ʻaʻole i delaminate ka mea composite!"

3. "Highlight scene" o ka hoao kaua maoli

Ua pupule ka ʻoihana aerospace no ka manawa lōʻihi. Hoʻohana ʻia nā lau turbine o kekahi hale hana ʻenekini mokulele ma Chengdukalapona silika ʻōmaʻomaʻoe hoʻoikaika i nā mea i hoʻokumu ʻia i ka ceramic-based composite, a ʻo ke kū ʻana o ka mahana e kū pololei a hiki i 1600 ℃. Nānā ka mea hoʻokele hoʻāʻo ʻo Lao Zhang i ka dashboard a droole: "Me kēia hana, pono nā ʻenekini jet e kāhea iā makuakāne!"

ʻOi aku ka hoʻohauʻoli ʻana o ka pale pākaukau o nā kaʻa ikehu hou. He 8 manawa ka ikaika o ke kalapona fiber composite bracket o ka mea hana ma Ningde ma hope o ka hui 'ana me ka carbide silicon green. I ka wā o ka hoʻāʻo ʻana, ua paʻi ka ʻenekini palekana ʻo Lao Li i ka puka kaʻa a ʻakaʻaka: "ʻĀnō ua like kēia kino kaʻa me ke komo ʻana i ʻekolu mau ʻāpana pale pale!"

He pupule ke kahua o 5G base station heat sinks. ʻO ka radiator composite e pili ana i ka aluminika o kahi mea hana ma Hangzhou he koena hoʻonui wela i hoʻomalu ʻia i 4.8 × 10⁻⁶/℃. Ua kuhikuhi ka luna ʻenehana i ka ʻikepili hoʻāʻo thermal cycle a haʻaheo: "Hiki ke hoʻololi ʻia mai -50 ℃ a 200 ℃, a ʻoi aku ka koʻikoʻi o ka loli nui ma mua o Virgo!"

4, "Long-termism" ma ka mooolelo kumu kuai

Mai nana i ke kumu kuai nui oʻōmaʻomaʻo silikon carbide micropowder, he mea pono ke helu 'oe i ka huina helu. Ua hana ka hale hana mīkini ma Chongqing i kahi helu helu: ʻoiai ua hoʻonui ʻia ke kumukūʻai o nā mea maka e 25%, ua hoʻonui ʻia ke ola o ka huahana, a ʻo ke kumukūʻai mālama i mālama ʻia i loko o ʻekolu makahiki ua lawa ia e kūkulu i kahi hale hana hou. Ua paʻi ka wahine kālā i ka calculator a ʻakaʻaka: "Ua ʻoi aku ka maikaʻi o kēia ʻoihana ma mua o ka ʻaiʻai!"

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

ʻAʻole ia he huahana manaʻo i ka hale hana ʻo ka ʻōmaʻomaʻo ʻōmaʻomaʻo carbide micropowder i kēia lā. Mai nā mokulele mokulele e lele ana i ka lewa a i nā kaʻa ikehu hou e holo ana ma ka honua, mai nā ʻāpana kelepona paʻa lima a hiki i 100 mika ka lōʻihi o ka makani turbine, aia ma nā wahi āpau. Wahi a ka poʻe kahiko o ka ʻoihana, ua hana kēia mea i ka lua i ke kaupaku hana o nā mea hana. I koʻu manaʻo, ʻaʻole kēia he mea hoʻonui maʻalahi wale nō, akā he "pana i ka lima" no ka ʻoihana hou. Inā hoʻomau kēia ʻano, hiki i kekahi lā ke hoʻohana i kā mākou papa ʻokiʻoki i kēia ʻenehana ʻeleʻele - ma hope o nā mea a pau, ʻo wai ka mea makemake ʻole i kā lākou mau mea kīhini i ka pae like me nā mea aerospace?
