Zosowa zapadziko lapansiEni ake ali ndi zida zamagetsi zamagetsi ndipo amawonetsa zinthu zambiri zowoneka bwino, zamagetsi, ndi maginito. Pambuyo pa rare earth nanomaterialization, imawonetsa mikhalidwe yambiri, monga kukula kwazing'ono, mawonekedwe apamwamba kwambiri, kuchuluka kwamphamvu, mawonekedwe amphamvu kwambiri, magetsi, maginito, superconductivity, zochita zambiri zama mankhwala, ndi zina zambiri, zomwe zimatha kusintha magwiridwe antchito ndi ntchito. za zipangizo ndi kupanga zipangizo zambiri zatsopano. Idzagwira ntchito yofunika kwambiri m'magawo apamwamba kwambiri monga zida zowunikira, zopangira kuwala, zida za kristalo, maginito, zipangizo za batri, Electroceramics, ceramics engineering, catalysts, etc.?
1. Kafukufuku waposachedwa wachitukuko ndi magawo ogwiritsira ntchito
1. Zinthu zosawerengeka zapadziko lapansi: Zosawerengeka padziko lapansi nano fulorosenti ufa (mtundu wa TV ufa, ufa wa nyali), zokhala ndi kuwala kowala bwino, zidzachepetsa kwambiri kuchuluka kwa dziko losowa lomwe amagwiritsidwa ntchito. Makamaka ntchitoY2O3, Eu2O3, Tb4O7, CeO2, Gd2O3. Wosankha Zida Zatsopano za Kanema Wotanthauzira Wamtundu Wapamwamba.?
2. Nano superconducting zipangizo: YBCO superconductors okonzeka ntchito Y2O3, makamaka woonda filimu zipangizo, ndi ntchito khola, mphamvu mkulu, processing zosavuta, pafupi siteji zothandiza, ndi ziyembekezo yotakata.?
3. Zosowa zapadziko lapansi nano maginito: zomwe zimagwiritsidwa ntchito ngati maginito kukumbukira, maginito madzimadzi, giant magnetoresistance, etc., kuwongolera kwambiri magwiridwe antchito, kupanga zida kuti zizigwira ntchito kwambiri komanso zocheperako. Mwachitsanzo, oxide giant magnetoresistance targets (REMnO3, etc.).?
4. Zoumba zadothi zapadziko lapansi zosawerengeka kwambiri: Electroceramics (zosensa zamagetsi, zida za PTC, zida za microwave, capacitors, thermistors, etc.) zokonzedwa ndi Ultra-fine kapena nanometer Y2O3, La2O3, Nd2O3, Sm2O3, etc., zomwe zida zake zamagetsi, zotentha katundu, ndi bata akhala bwino kwambiri, ndi mbali yofunika ya kukweza zipangizo zamagetsi. Ceramics sintered pa kutentha kwapansi, monga nano Y2O3 ndi ZrO2, ali ndi mphamvu zolimba ndi zolimba, ndipo amagwiritsidwa ntchito pazida zosavala monga ma fani ndi zida zodulira; Kuchita kwa ma multilayer capacitor ndi zida za microwave zopangidwa ndi nano Nd2O3, Sm2O3, ndi zina zasinthidwa kwambiri.?
5. Ma nanocatalysts a Rare Earth: Muzinthu zambiri zamakhemikolo, zopangira zapadziko lapansi zachilendo zimagwiritsidwa ntchito. Ngati ma nanocatalysts osowa padziko lapansi agwiritsidwa ntchito, ntchito yawo yothandiza komanso yogwira ntchito bwino idzawongolera kwambiri. CeO2 nano ufa wamakono uli ndi ubwino wochita zinthu zambiri, mtengo wotsika komanso moyo wautali wautumiki m'galimoto yotulutsa mpweya, ndipo walowa m'malo mwazitsulo zamtengo wapatali, ndikugwiritsira ntchito pachaka matani masauzande.?
6. Choyamwitsa cha ultraviolet chosowa padziko lapansi:Nano CeO2ufa umayamwa mwamphamvu ku cheza cha ultraviolet, ndipo umagwiritsidwa ntchito mu zodzoladzola zoteteza ku dzuwa, ulusi woteteza ku dzuwa, magalasi agalimoto, ndi zina zambiri?
7. Kupukuta mwatsatanetsatane padziko lapansi: CeO2 imakhala ndi zotsatira zabwino zopukutira pagalasi ndi zinthu zina. Nano CeO2 ili ndi kupukuta bwino kwambiri ndipo yakhala ikugwiritsidwa ntchito muzitsulo zamadzimadzi, zopangira silicon, kusungirako magalasi, ndi zina zotero. Mwachidule, kugwiritsa ntchito mapulaneti osowa padziko lapansi kwangoyamba kumene ndipo akukhazikika m'munda wa zipangizo zamakono zatsopano, zokhala ndi apamwamba. mtengo wowonjezedwa, kuchuluka kwa ntchito, kuthekera kwakukulu, komanso chiyembekezo chamalonda chodalirika.?
2, Kukonzekera luso
Pakadali pano, kupanga ndi kugwiritsa ntchito ma nanomatadium kwakopa chidwi kuchokera kumaiko osiyanasiyana. China nanotechnology ikupitabe patsogolo, ndipo kupanga mafakitale kapena kuyesa kuyesa kwachitika bwino mu nanoscale SiO2, TiO2, Al2O3, ZnO2, Fe2O3 ndi zipangizo zina za ufa. Komabe, njira zomwe zikupanga pano komanso ndalama zambiri zopangira ndizofooka zake zowopsa, zomwe zingakhudze kufalikira kwa ma nanomatadium. Chifukwa chake, kuwongolera kosalekeza ndikofunikira.?
Chifukwa cha mawonekedwe apadera amagetsi ndi ma radius akulu a Atomiki a zinthu zapadziko lapansi, zomwe zimapangidwira zimasiyana kwambiri ndi zinthu zina. Chifukwa chake, njira yokonzekera komanso ukadaulo wapambuyo pamankhwala osowa padziko lapansi nano oxides nawonso amasiyana ndi zinthu zina. Njira zazikulu zofufuzira ndi izi:?
1. Njira ya mpweya: kuphatikizapo mpweya wa oxalic acid, mpweya wa carbonate, mpweya wa hydroxide, mpweya wofanana, mvula yowonongeka, ndi zina zotero. mankhwala apamwamba. Koma ndizovuta kusefa komanso zosavuta kuziphatikiza?
2. Hydrothermal njira: Imathandizira ndi kulimbikitsa hydrolysis anachita ma ion pansi pa kutentha ndi kupanikizika, ndi kupanga omwazika nanocrystalline phata. Njira imeneyi angapeze nanometer ufa ndi yunifolomu kubalalitsidwa ndi yopapatiza tinthu kukula kugawa, koma pamafunika kutentha ndi mkulu kuthamanga zida, amene ndi okwera mtengo ndi osatetezeka ntchito.?
3. Njira ya gel osakaniza: Ndi njira yofunikira pokonzekera zinthu zakuthupi, ndipo imagwira ntchito yofunika kwambiri pakuphatikizika kwachilengedwe. Pa kutentha otsika, mankhwala organometallic kapena organic complexes akhoza kupanga sol kudzera polymerization kapena hydrolysis, ndi kupanga gel osakaniza pansi zinthu zina. Kutentha kwina kwina kumatha kutulutsa Zakudyazi za Mpunga zokulirapo komanso zobalalika bwino. Njirayi imatha kuchitidwa pansi pazikhalidwe zofatsa, zomwe zimapangitsa ufa wokhala ndi malo okulirapo komanso dispersibility bwino. Komabe, nthawi yochitapo ndi yayitali ndipo imatenga masiku angapo kuti amalize, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zamakampani?
4. Njira yolimba ya gawo: kuwonongeka kwakukulu kwa kutentha kumachitika kudzera pawiri olimba kapena apakatikati Dry media reaction. Mwachitsanzo, osowa nthaka nitrate ndi asidi oxalic amasakanizidwa ndi olimba gawo mpira mphero kupanga wapakatikati osowa lapansi Oxalate, amene ndiye kuwola pa kutentha kwambiri kupeza kopitilira muyeso-bwino ufa. Njirayi imakhala ndi magwiridwe antchito apamwamba, zida zosavuta, komanso kugwiritsa ntchito kosavuta, koma ufa womwe umakhala ndi mawonekedwe osakhazikika komanso osagwirizana.?
Njirazi siziri zapadera ndipo sizingagwire ntchito mokwanira pantchito zamafakitale. Pali njira zambiri zokonzekera, monga njira ya organic microemulsion, alcoholysis, etc.?
3, Kupita patsogolo kwa chitukuko cha mafakitale
Kupanga mafakitale nthawi zambiri sikutengera njira imodzi, koma kumatengera mphamvu ndikukwaniritsa zofooka, ndikuphatikiza njira zingapo kuti mukwaniritse zogulitsa zapamwamba, zotsika mtengo, komanso njira zotetezeka komanso zoyenera zomwe zimafunikira pakugulitsa. Guangdong Huizhou Ruier Chemical Technology Co., Ltd. Pambuyo pa njira zambiri zowunikira komanso kuyesa kosawerengeka, njira yomwe ili yoyenera kupanga mafakitale - njira ya microwave gel. Ubwino waukulu waukadaulo uwu ndikuti: mawonekedwe a gel oyambilira a masiku 10 amafupikitsidwa mpaka tsiku limodzi, kotero kuti magwiridwe antchito amachulukirachulukira nthawi 10, mtengo wake umachepetsedwa kwambiri, ndipo mtundu wazinthu ndi wabwino, malo apamwamba ndi akulu. , Mayesero a ogwiritsa ntchito ndiabwino, mtengo wake ndi 30% wotsika kuposa wa zinthu zaku America ndi Japan, zomwe zimapikisana kwambiri padziko lonse lapansi, Kukwaniritsa mulingo wapamwamba wapadziko lonse lapansi.?
Posachedwapa, kuyesa kwa mafakitale kwachitika pogwiritsa ntchito njira ya mpweya, makamaka pogwiritsa ntchito madzi a ammonia ndi ammonia carbonate kuti ayambe kugwa, komanso kugwiritsa ntchito zosungunulira za organic pofuna kutaya madzi m'thupi ndi mankhwala apamwamba. Njirayi ili ndi ndondomeko yosavuta komanso yotsika mtengo, koma khalidwe la mankhwala ndi losauka, ndipo pali ma agglomerations omwe amafunika kuwongolera ndi kuwongolera.
China ndi dziko lalikulu lomwe lili ndi chuma chosowa padziko lapansi. Kupanga ndi kugwiritsa ntchito ma nanomatadium osowa padziko lapansi kwatsegula njira zatsopano zogwiritsira ntchito bwino zinthu zapadziko lapansi, kukulitsa kuchuluka kwa ntchito zosowa padziko lapansi, kulimbikitsa chitukuko cha zida zatsopano zogwirira ntchito, kuchulukitsa kutumizidwa kunja kwa zinthu zamtengo wapatali, ndikuwongolera zakunja. kusinthana zopezera. Izi zili ndi tanthauzo lofunikira posintha maubwino azinthu kukhala zabwino zachuma.
