I-Zirconia Nanopowder: Into Entsha Yefoni “Emuva” ye-5G

Umthombo: Isayensi Nobuchwepheshe Nsuku Zonke: Inqubo yokukhiqiza yendabuko ye-zirconia powder izokhiqiza inani elikhulu lemfucuza, ikakhulukazi inani elikhulu lamanzi angcolile ane-alkaline agxilile okunzima ukuwaphatha, okubangela ukungcoliswa okukhulu kwemvelo.Ukugaya ibhola elinamandla amakhulu kuwubuchwepheshe bokulungiselela okonga amandla futhi obusebenzayo, obungathuthukisa ukubumbana nokuhlakazeka kwe-zirconia ceramics futhi kube nethuba elihle lokufaka isicelo sezimboni. Ngokufika kobuchwepheshe be-5G, amafoni ahlakaniphile azishintsha buthule “imishini yawo. ”.Ukuxhumana kwe-5G kusebenzisa i-spectrum engaphezu kuka-3 gigahertz (Ghz), futhi ubude bayo begagasi obungamamilimitha bufushane kakhulu.Uma iselula ye-5G isebenzisa indiza yasemuva yensimbi, izophazamisa kakhulu noma ivikele isignali.Ngakho-ke, izinto ze-Ceramic ezinezici zokungavimbeli isignali, ubulukhuni obuphezulu, ukubona okuqinile nokusebenza okuhle kakhulu okushisayo okuseduze nezinto zensimbi kancane kancane kube yisinqumo esibalulekile ezinkampanini zamaselula ukungena enkathini ye-5G.U-Bao Jinxiao, uprofesa e-Inner Mongolia University of Science and Technology, utshele izintatheli ukuthi njengezinto ezibalulekile ze-inorganic nonmetallic, izinto ezintsha ze-ceramic seziyisinqumo esingcono kakhulu sezinto ezisetshenziswayo ze-smart phone backboard. ngokuphuthuma.U-Wang Sikai, umphathi jikelele we-Inner Mongolia Jingtao Zirconium Industry Co., Ltd. (kamuva ebizwa ngokuthi i-Jingtao Zirconium Industry), utshele intatheli ukuthi ngokolwazi olukhishwe yi-Counterpoint, isikhungo socwaningo esaziwayo emhlabeni, ukuthunyelwa kwama-smartphone emhlabeni jikelele ifinyelela kumayunithi ayizigidi eziyizinkulungwane eziyi-1.331 ngo-2020. Ngokukhula kwesidingo se-zirconia ceramics esetshenziswa kumabhodi angemuva omakhalekhukhwini, i-R&D yayo kanye nobuchwepheshe bokulungiselela nakho sekudonse ukunaka okukhulu. indawo yokusebenza enokhahlo ukuthi izinto zensimbi, izinto ze-polymer nezinye izinto eziningi zobumba azikwazi.Njengezingxenye zesakhiwo, kusetshenziswe imikhiqizo ye-zirconia ceramic ezimbonini eziningi njengamandla, i-aerospace, imishini, imoto, ukwelashwa, njll., futhi ukusetshenziswa komhlaba wonke ngonyaka kungaphezu kwamathani angu-80,000. Ngokufika kwenkathi ye-5G, imishini yobumba ine kuboniswe izinzuzo ezinkulu zobuchwepheshe ekwenzeni ama-backboards omakhalekhukhwini, kanye ne-zirconia ceramics inethuba elibanzi lentuthuko."Ukusebenza kwe-zirconia ceramics kuncike ngokuqondile ekusebenzeni kwezimpushana, ngakho-ke ukuthuthukisa ubuchwepheshe bokulungiselela obulawulekayo bezimpushana ezisebenza kakhulu, sekuyisixhumanisi esibucayi kakhulu ekulungiseleleni i-zirconia ceramics kanye nokuthuthukiswa kwamadivayisi e-ceramic e-zirconia asebenza kahle kakhulu.“Wang Sikai washo ngokungananazi.Indlela yokugaya ibhola enamandla amakhulu eluhlaza ifunwa kakhulu ngochwepheshe.Ukukhiqizwa kwasekhaya kwe-zirconia nano-powder ngokuvamile kusebenzisa inqubo yamakhemikhali emanzi, futhi i-oxide yomhlaba engavamile isetshenziswa njenge-stabilizer ukukhiqiza i-zirconia nano-powder.Le nqubo inezici zomthamo omkhulu wokukhiqiza kanye nokufana okuhle kwezingxenye zamakhemikhali zemikhiqizo, kodwa ukonakala ukuthi kuzokhiqizwa imfucuza eningi ohlelweni lokukhiqiza, ikakhulukazi inani elikhulu lamanzi angcolile ane-alkali ane-concentration ephansi okunzima ukuwaphatha, futhi uma ingaphathwa kahle, izodala ukungcola okubi kakhulu kanye nokulimala kwemvelo.“Ngokocwaningo, Kuthatha cishe amathani angu-50 amanzi ukukhiqiza ithani elilodwa le-yttria-stabilized zirconia ceramic powder, elizokhiqiza amanzi amaningi angcolile, futhi ukubuyiswa nokwelashwa kwamanzi angcolile kuzokhuphula kakhulu izindleko zokukhiqiza.“Kusho uWang Sikai.Ngokuthuthukiswa komthetho waseShayina wokuvikela imvelo, amabhizinisi alungiselela i-zirconia nano-powder ngendlela yamakhemikhali emanzi abhekene nobunzima obungakaze bubonwe ngaphambili.Ngakho-ke, kunesidingo esiphuthumayo sokuthuthukisa ubuchwepheshe bokulungiselela obuluhlaza kanye nezindleko eziphansi ze-zirconia nano-powder.“Ngalesi sizindalwazi, sekuyisizinda socwaningo ukulungisa i-zirconia nano-powder ngenqubo yokukhiqiza amandla ahlanzekile futhi aphansi, phakathi kwawo indlela yokugaya ibhola elinamandla okuyiyona efunwa kakhulu yimibuthano yesayensi nezobuchwepheshe.“Inoveli ka-Bao Jin.Ukugaya ibhola elinamandla amakhulu kubhekisela ekusetshenzisweni kwamandla emishini ukuze kubangele ukusabela kwamakhemikhali noma ukwenza izinguquko esakhiweni nasezimpahleni zezinto zokwakha, ukuze kulungiswe izinto ezintsha.Njengobuchwepheshe obusha, Kunganciphisa ngokusobala amandla okwenza kusebenze, kucwengisise usayizi wokusanhlamvu, kuthuthukise kakhulu ukufana kokusabalalisa kwezinhlayiya zempushana, kuthuthukise inhlanganisela yokuxhumana phakathi kwama-substrates, kukhuthaze ukusakazeka kwama-ion aqinile futhi kubangele ukusabela kwamakhemikhali okunokushisa okuphansi, ukuthuthukisa ukubumbana kanye nokuhlakazeka kwezinto.Iwubuchwepheshe bokulungisa izinto ezonga amandla futhi obuphumelelayo obunamathemba amahle okusebenza kwezimboni.Indlela eyingqayizivele yokwenza imibala idala izitsha zobumba ezimibalabala.Emakethe yamazwe ngamazwe, izinto ze-zirconia nano-powder zingene esigabeni sokuthuthukiswa kwezimboni.UWang Sikai utshele izintatheli ukuthi: “Emazweni athuthukile nasezifundeni ezifana ne-United States, Western Europe kanye neJapan, izinga lokukhiqizwa kwe-zirconia nano-powder likhulu futhi imininingwane yomkhiqizo iphelele.Ikakhulukazi izinkampani zaseMelika nezaseJapan, Inezinzuzo ezisobala zokuncintisana kulungelo lobunikazi le-zirconia ceramics.Ngokusho kukaWang Sikai, okwamanje, imboni entsha yokukhiqiza i-ceramic yaseShayina isesigabeni sokuthuthuka ngokushesha, futhi isidingo se-ceramic powder sikhula unyaka nonyaka, ngakho-ke kuyaphuthuma kakhulu ukuthuthukisa inqubo yokukhiqiza i-nanometer zirconia entsha.Eminyakeni emibili edlule, ezinye izikhungo zocwaningo lwasekhaya kanye namabhizinisi nawo aqale ukucwaninga ngokuzimela futhi akhiqize i-zirconia nano-powder, kodwa iningi locwaningo nentuthuko kusesesigabeni sokukhiqizwa kocwaningo oluncane elabhorethri, nokukhipha okuncane. kanye nenhlobonhlobo eyodwa.Kuphrojekthi ye-"Color Rare Earth Zirconia Nanopowder" eyenziwa yi-Ceramic Zirconia Industry, i-zirconia nanopowder yalungiselelwa indlela yokusabela ye-high-energy milling solid-state. -impushana yokusanhlamvu ehlanganisiwe enobukhulu obungama-nanometer angu-100 ingatholakala, engenakho ukungcola, izindleko eziphansi kanye nokuzinza kweqoqo elihle.”Kusho uBao Xin.Ubuchwepheshe bokulungiselela abukwazi nje ukuhlangabezana nezidingo zempushana ze-5G umakhalekhukhwini we-ceramic backboard, i-thermal barrier coating materials yezinjini ze-turbine yezindiza, amabhola e-ceramic, imimese ye-ceramic neminye imikhiqizo, kodwa futhi ingathandwa futhi isetshenziswe ekulungiseleleni izimpushana eziningi ze-ceramic ezifana njengokulungiswa kwe-powder eyinhlanganisela ye-cerium oxide.Ngokusho komshini wokukhetha umbala ozithuthukisile, ithimba lezobuchwepheshe le-Ceramic Zirconium Industry lamukele ukuhlanganiswa kwesigaba esiqinile kanye nendlela eyinhlanganisela yokufaka imibala ngaphandle kokwethula ama-ion ensimbi engeziwe ngokusebenzisa inqubo yokwenza kahle.I-zirconia ceramics elungiselelwe le ndlela ayinayo kuphela ukugcwala kombala okuphezulu nokuhle. ukumanzisa, kodwa futhi akuthinti izakhiwo zangempela zemishini ye-zirconia ceramics.“Usayizi wokuqala wezinhlayiyana zombala ongavamile we-zirconia powder okhiqizwa ngokusekelwe ebuchwephesheni obusha i-nanometer, enezici zobukhulu bezinhlayiyana ezifanayo, umsebenzi wokushisa ophezulu, izinga lokushisa eliphansi le-sintering nokunye.Uma kuqhathaniswa nenqubo yokukhiqiza yendabuko, ukusetshenziswa kwamandla okuphelele kuncishiswa kakhulu.Ukusebenza kahle kokukhiqiza kanye nesivuno sokucubungula i-ceramic sithuthukiswa kakhulu.Imishini ye-ceramic ethuthukisiwe elungiselelwe yile ndlela inezakhiwo ezinhle kakhulu ezifana namandla aphezulu, ukuqina okuphezulu kanye nobunzima obukhulu."Kusho uWang Sikai.
