Zirconia Nanopowder: He Mea Hou no "Ma hope" 5G Kelepona Paʻa

Puna: ʻEpekema a me ʻenehana i kēlā me kēia lā: ʻO ke kaʻina hana kuʻuna o ka pauka zirconia e hoʻopuka i ka nui o ka ʻōpala, ʻoi aku ka nui o ka wai alkaline haʻahaʻa haʻahaʻa i paʻakikī ke mālama ʻia, e hoʻohaumia ai i ke kaiapuni.ʻO ka wili pōleʻa kiʻekiʻe he mea hoʻolaʻa ikehu a maikaʻi hoʻi ka ʻenehana hoʻomākaukau, hiki ke hoʻomaikaʻi i ka compactness a me ka dispersibility o ka zirconia ceramics a loaʻa kahi manaʻo noiʻi ʻoihana maikaʻi. ”.Hoʻohana ke kamaʻilio 5G i ka spectrum ma luna o 3 gigahertz (Ghz), a pōkole loa kona lōʻihi hawewe millimeter.Inā hoʻohana ke kelepona paʻa lima 5G i kahi kuamoʻo metala, e hoʻopilikia nui ia a pale paha i ka hōʻailona.No laila, ʻo nā mea seramika me nā hiʻohiʻona o ka pale ʻole hōʻailona, ​​ka paʻakikī kiʻekiʻe, ka ʻike ikaika a me ka hana wela maikaʻi kokoke i nā mea metala ua lilo i mea koho nui no nā hui kelepona paʻa e komo i ka wā 5G.Ua haʻi aku ʻo Bao Jinxiao, he polopeka ma Inner Mongolia University of Science and Technology, ma ke ʻano he mea koʻikoʻi koʻikoʻi nonmetallic waiwai, ua lilo nā mea seramika hou i mea koho maikaʻi loa no nā mea kelepona kelepona akamai. me ka wikiwiki.Ua haʻi aku ʻo Wang Sikai, ka luna nui o Inner Mongolia Jingtao Zirconium Industry Co., Ltd. (i kapa ʻia ʻo Jingtao Zirconium Industry), e like me ka ʻikepili i hoʻokuʻu ʻia e Counterpoint, kahi ʻoihana noiʻi kaulana i ka honua, e hoʻouna ʻia nā moku kelepona honua. hiki i 1.331 biliona mau ʻāpana i 2020. Me ka piʻi nui ʻana o ka noi no nā seramika zirconia i hoʻohana ʻia i nā backboards kelepona paʻa, ua ʻike nui ʻia kāna R&D a me ka ʻenehana hoʻomākaukau. ʻO ke ʻano hana koʻikoʻi ʻaʻole kūpono i nā mea metala, nā mea polymer a me nā mea ʻē aʻe.Ma keʻano he mea hoʻolālā, ua hoʻohanaʻia nā huahana zirconia ceramic i nāʻoihana he nui e like me ka ikehu, aerospace, mīkini, kaʻa, ka lāʻau lapaʻau, a me nā mea'ē aʻe, aʻoi aku ka nui o ka hoʻohana makahiki honua ma luna o 80,000 tons. ʻoi aku ka maikaʻi o ka ʻenehana i ka hana ʻana i nā backboards kelepona paʻalima, a ʻo ka zirconia ceramics i ʻoi aku ka nui o ka hoʻomohala ʻana."ʻO ka hana o ka zirconia ceramics e pili pono ana i ka hana o nā pauka, no laila e hoʻomohala ana i ka ʻenehana hoʻomākaukau controllable o nā pauka hana kiʻekiʻe, ua lilo ia i loulou koʻikoʻi loa i ka hoʻomākaukau ʻana i nā seramika zirconia a me ka hoʻomohala ʻana i nā mea hana kiʻekiʻe zirconia ceramic.“Ua ʻōlelo pololei ʻo Wang Sikai.ʻImi nui ʻia e ka poʻe akamai ke ʻano wili pōleʻa kiʻekiʻe o ka ikehu ʻōmaʻomaʻo.ʻO ka hana home o ka zirconia nano-powder ka hapa nui o ka hoʻohana ʻana i ke kaʻina hana kemika, a ua hoʻohana ʻia ka honua oxide ma ke ʻano he stabilizer e hana ai i ka zirconia nano-powder. ʻO kēia kaʻina hana nā hiʻohiʻona o ka mana hana nui a me ka kūlike maikaʻi o nā mea kemika o nā huahana, akā ʻo ka hemahema. e hana ʻia ka nui o ka ʻōpala i ke kaʻina hana, ʻoi aku ka nui o ka wai ʻōpala alkaline haʻahaʻa i paʻakikī ke mālama ʻia, a inā ʻaʻole e mālama pono ʻia, e hoʻohaumia nui ʻia a pōʻino i ke kaiaola."E like me ka noiʻi ʻana, lawe ʻia ma kahi o 50 tons o ka wai e hana i hoʻokahi ton o yttria-stabilized zirconia ceramic pauka, e hoʻohua ai i ka nui o ka wai ʻino, a ʻo ka hoʻihoʻi ʻana a me ka mālama ʻana i ka wai ʻino e hoʻonui nui i ke kumukūʻai hana."wahi a Wang Sikai.Me ka hoʻomaikaʻi ʻana i ke kānāwai mālama kaiapuni o Kina, ʻo nā ʻoihana e hoʻomākaukau ana i ka zirconia nano-powder ma ke ʻano kemika pulu e kū nei i nā pilikia ʻike ʻole."E kū'ē i kēia kumu, ua lilo ia i wahi wela no ka hoʻomākaukau ʻana i ka zirconia nano-powder e ka hoʻomaʻemaʻe a me ka haʻahaʻa haʻahaʻa o ka hoʻohana ʻana i ka ikehu hana hana, ma waena o ke ʻano o ka wili pōlele kiʻekiʻe ka mea i ʻimi nui ʻia e nā pōʻai ʻepekema a me ka ʻenehana.“Ka moolelo a Bao Jin.ʻO ka wili pōleʻa kiʻekiʻe e pili ana i ka hoʻohana ʻana i ka ikehu mechanical e hoʻoulu ai i nā hopena kemika a i ʻole e hoʻohuli i nā loli i ke ʻano a me nā waiwai o nā mea, i mea e hoʻomākaukau ai i nā mea hou.Ma ke ʻano he ʻenehana hou, hiki iā ia ke hōʻemi i ka ikehu hoʻoulu ʻana, hoʻomaʻemaʻe i ka nui o ka palaoa, hoʻomaikaʻi nui i ka hoʻohele like ʻana o nā ʻāpana pauka, hoʻonui i ka hui pū ʻana ma waena o nā substrates, hoʻoikaika i ka diffusion o nā ion paʻa a hoʻoulu i nā hopena kemika haʻahaʻa. ka hoʻomaikaʻi ʻana i ka compactness a me ka dispersibility o nā mea.He ʻenehana hoʻomaʻamaʻa hoʻolaʻa ikehu a me ka maikaʻi me ka noiʻi ʻoihana maikaʻi.I ka mākeke honua, ua komo nā mea zirconia nano-powder i ke kahua o ka hoʻomohala ʻoihana.Ua haʻi ʻo Wang Sikai i ka poʻe nūhou: "Ma nā ʻāina hoʻomohala a me nā wahi e like me ʻAmelika Hui Pū ʻIa, ʻEulopa Komohana a me Iapana, nui ka nui o ka hana ʻana o ka zirconia nano-powder a ua paʻa nā kikoʻī huahana.ʻOi aku ka nui o nā hui multinational ʻAmelika a me Iapana, Loaʻa iā ia nā pōmaikaʻi hoʻokūkū ma ka patent o zirconia ceramics.Wahi a Wang Sikai, i kēia manawa, aia ka ʻoihana hana ceramic hou o Kina i kahi pae o ka hoʻomohala wikiwiki, a ke piʻi nei ka noi no ka pauka keramika i kēlā me kēia makahiki, no laila ʻoi aku ka wikiwiki o ka hoʻomohala ʻana i ke kaʻina hana o ka nanometer zirconia hou.I nā makahiki ʻelua i hala iho nei, ua hoʻomaka kekahi mau ʻimi noiʻi kūloko a me nā ʻoihana e noiʻi kūʻokoʻa a hana i ka zirconia nano-powder, akā ʻo ka hapa nui o ka noiʻi a me ka hoʻomohala ʻana aia nō i ke kahua o ka hana hoʻokolohua liʻiliʻi i loko o ka hale keʻena, me ka liʻiliʻi. a me nā ʻano like ʻole.Ma ka papahana o "Color Rare Earth Zirconia Nanopowder" i hoʻokō ʻia e Ceramic Zirconia Industry, ua hoʻomākaukau ʻia ʻo zirconia nanopowder e ka wili pōleʻa kiʻekiʻe o ka ikaika. -ʻO ka pauka palaoa agglomerated me ka nui o 100 nanometers hiki ke loaʻa, ʻaʻohe pollution, haʻahaʻa haʻahaʻa a me ka paʻa paʻa maikaʻi.wahi a Bao Xin.ʻAʻole hiki i ka ʻenehana hoʻomākaukau ke hoʻokō wale i nā koi o ka pauka o 5G kelepona paʻa ceramic backboard, thermal barrier coating material no ka mokulele turbine engines, ceramic balls, ceramic knives a me nā huahana ʻē aʻe, akā hiki ke hoʻolaha ʻia a hoʻohana ʻia i ka hoʻomākaukau ʻana i nā pauka seramika e like me e like me ka cerium oxide composite pauda hoʻomākaukau.Wahi a ka mīkini kala i hoʻomohala ʻia, ua hoʻohana ka hui ʻenehana o Ceramic Zirconium Industry i ka synthesis solid-phase a me ke ʻano hana hoʻohui no ke kala me ka ʻole o ka hoʻokomo ʻana i nā ion metala ʻē aʻe ma o ke kaʻina hana optimization. ka wettability, akā ʻaʻole pili i nā waiwai mechanical kumu o ka zirconia ceramics."ʻO ka nanometer ka nui o ka nui o ka kala rare earth zirconia pauka i hana ʻia ma muli o ka ʻenehana hou, nona nā hiʻohiʻona o ka nui o nā ʻāpana like ʻole, ka hana sintering kiʻekiʻe, ka wela sintering haʻahaʻa a pēlā aku.Ke hoʻohālikelikeʻia me ke kaʻina hana maʻamau, ua hoʻemi nuiʻia ka hoʻohanaʻana i ka ikehu.ʻO nā mea hana seramika holomua i hoʻomākaukau ʻia e kēia ʻano he mau waiwai maikaʻi loa e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe a me ka paʻakikī kiʻekiʻe."wahi a Wang Sikai.
