Pakadali pano, kupanga komanso 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 zimakhala zosiyana 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:
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.Njirayi ingapeze ufa wa nanometer ndi kubalalitsidwa yunifolomu ndi kugawa kwakung'ono kwa tinthu, koma kumafuna kutentha kwakukulu ndi zida zothamanga kwambiri, zomwe zimakhala zodula komanso zosatetezeka kuti zigwire 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 kanthu ndi yayitali ndipo imatenga masiku angapo kuti ithe, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zofunikira zamakampani.
4. Njira yolimba ya gawo: kuwonongeka kwa kutentha kwakukulu kumachitika kudzera mumagulu olimba kapena zochitika zapakatikati zolimba.Mwachitsanzo, osowa earth nitrate ndi asidi oxalic amasakanizidwa ndi olimba gawo mpira mphero kupanga wapakatikati ya osowa earth oxalate, amene ndiye kuwola pa kutentha kwambiri kupeza ultrafine 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.Palinso njira zambiri zokonzekera, monga njira ya organic microemulsion, alcoholysis, etc.
Kuti mudziwe zambiri pls omasuka kulankhula nafe
