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 aphezulu kuwubuchwepheshe bokulungisa izinto ezonga 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 njengento ebalulekile ye-inorganic nonmetallic, izinto ezintsha ze-ceramic seziyisinqumo esingcono kakhulu sezinto zokwakha ze-backboard zamafoni ahlakaniphile. U-Wang Sikai, umphathi jikelele we-Inner Mongolia Jingtao Zirconium Industry Co., Ltd. (ngemuva kwalokhu ebizwa ngokuthi i-Jingtao Zirconium Industry), utshele intatheli ukuthi ngokolwazi olukhishwe yi-Counterpoint, isikhungo socwaningo esaziwayo emhlabeni wonke, ukuthunyelwa kwama-smartphone emhlabeni wonke kuzofinyelela kumayunithi ayizigidi eziyizinkulungwane ezingu-1.331 ngo-2020. Ngenxa yokukhula kwesidingo sefoni ye-ceramic kanye ne-ceramic D yokulungiswa kwezingcingo ze-ceramic ezisetshenziswa ku-zirconia D futhi idonse ukunaka okukhulu.Njengempahla entsha ye-ceramic enokuqukethwe okuphezulu kakhulu kobuchwepheshe, i-zirconia ceramic material ingasebenza endaweni enzima yokusebenza lapho izinto zensimbi, izinto ze-polymer nezinye izinto eziningi zobumba azikwazi ukuzisebenza. 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 ibonise izinzuzo ezinkulu zobuchwepheshe ekwenzeni ama-backboards omakhalekhukhwini, kanye ne-zirconia prospect yokuthuthukiswa kwe-ceramic. "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. "Wang Sikai uthe 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 okubi ukuthi inani elikhulu lemfucuza lizokhiqizwa ekukhiqizeni, ikakhulukazi inani elikhulu le-alkali elinzima futhi elinzima ukuphatha amanzi ane-alkali. ngokufanelekile, kuzodala ukungcoliswa okukhulu kanye nomonakalo endaweni ezungezile. "Ngokocwaningo, Kuthatha cishe amathani angu-50 amanzi ukukhiqiza ithani elilodwa le-yttria-stabilized zirconia ceramic powder, elizokhiqiza amanzi amaningi angcolile, futhi ukubuyiswa nokuphathwa 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. “Ngokwalesi 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 kwenze ukusabela kwamakhemikhali okunokushisa okuphansi, ngaleyo ndlela kuthuthukise ukubumbana 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. U-Wang Sikai utshele izintatheli: "Emazweni athuthukile nasezifundeni ezifana ne-United States, i-Western Europe ne-Japan, isikali sokukhiqizwa kwe-zirconia nano-powder sikhulu futhi imininingwane yomkhiqizo isiphelele. Ikakhulukazi izinkampani zamazwe ngamazwe zaseMelika naseJapane, zinezinzuzo ezicacile zokuncintisana kulungelo lobunikazi be-zirconia ceramics. Ngokusho kukaWang Sikai, okwamanje, imboni ye-ceramic ekhulayo ikhula ngokushesha esiteji sokukhiqiza i-ceramic ngonyaka we-ceramic. ngonyaka, ngakho-ke kuyaphuthuma kakhulu ukuthuthukisa inqubo yokukhiqiza i-nanometer zirconia entsha kule minyaka emibili edlule, ezinye izikhungo zocwaningo zasekhaya kanye namabhizinisi nawo aqale ukucwaninga ngokuzimela futhi akhiqize i-zirconia nano-powder, kepha iningi locwaningo nentuthuko kusesigabeni sokukhiqizwa kwesivivinyo esincane elabhorethri, ngokukhipha okuncane kanye nephrojekthi eyodwa ye-Cerconia esetshenziswa yi-Earth Imboni yeZirconia, i-zirconia nanopowder yalungiselelwa indlela yokusabela eqinile yebhola enamandla amakhulu.” Amanzi asetshenziswa njengendawo yokugaya ukuze agaye futhi acwengisise izinhlayiya, ukuze kutholakale impushana yokusanhlamvu engahlanganisiwe enosayizi wama-nanometer angu-100, engenakho ukungcola, izindleko eziphansi nokuzinza okuhle kweqoqo.” U-Bao Xin uthe ubuchwepheshe bokulungiselela abukwazi ukuhlangabezana kuphela nezidingo zempushana ze-5G ye-ceramic backboard, izinto ezishisayo zokuvimbela izinjini ze-aviation turbine, amabhola e-ceramic, imimese ye-ceramic neminye imikhiqizo, kodwa futhi bungasakazwa futhi busetshenziswe ekulungiseleleni izimpushana ze-ceramic ezifana ne-cerium oxide composite powder yokulungiselela, i-Industry Solid Mechanical ye-Technical ethuthukisiwe ye-Zimegranium. I-synthesis kanye nendlela ehlanganisiwe yokufaka imibala ngaphandle kokwethula ama-ion ensimbi engeziwe ngokusebenzisa inqubo yokwenza kahle.I-ceramics ye-zirconia elungiselelwe le ndlela ayinayo kuphela ukugcwala kombala okuphezulu kanye nokumanzisa okuhle, kodwa futhi ayithinti izakhiwo zangempela zemishini ye-zirconia ceramics "Usayizi wezinhlayiyana zangempela zombala ongavamile we-zirconia powder okhiqizwa ngokusekelwe kubuchwepheshe obusha yi-nanometer yobukhulu obuphansi be-sinter, umsebenzi we-sinter nezici zokushisa eziphansi. ku. 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.
