Nanotechnology imatha kupanga zinthu zambiri zachikhalidwe "zatsopano".Kugwiritsa ntchito ukadaulo wa nano-modification popanga zinthu zachikhalidwe kumatha kukonza kapena kupeza ntchito zingapo.Nano ceramic zokutira ndi zokutira zophatikizika zambiri zopangidwa ndi zida zosinthidwa za ceramic ndi zida za nano, zomwe zimakhala ndi mphamvu yotchinjiriza kwambiri komanso kukana kwa dzimbiri.Pakati pawo, kuwonjezera kwa nano zipangizo ali ndi makhalidwe ambiri, monga mkulu-kachulukidwe kusindikiza ndi ntchito odana dzimbiri zipangizo ceramic, odana ndi fouling ndi kudziyeretsa kudziyeretsa, kuuma, kulimba, kuvala kukana, kutentha kukana, antistatic katundu, UV. kukana, kutsekereza kutentha ndi zinthu zina zambiri zimasinthidwa bwino.
Nano ceramic powders akhala akugwiritsidwa ntchito kwambiri m'magawo apamwamba kwambiri monga zoumba zabwino, zoumba zogwira ntchito, bioceramics ndi zipangizo zabwino zamakina chifukwa cha makina awo, kuwala ndi magetsi, ndipo akhala mwala wapangodya wa chitukuko chamakono cha zipangizo zamakono.
Zotsatirazi zikuwonetsa ma nano ufa angapo omwe amagwiritsidwa ntchito muzoumba:
1. Nano silicon carbide (SiC) ndindevu za silicon carbide
Silicon carbide nano ufa ndi ndevu zili ndi zinthu zabwino kwambiri, monga kulimba kwambiri, kuuma, zotanuka modulus, kulemera kopepuka, kukana kutentha, kukana dzimbiri, komanso kukhazikika kwamankhwala.Kugwiritsa ntchito silicon carbide ku zida zophatikizika za ceramic kumatha kupititsa patsogolo kuphulika koyambirira kwa zoumba, komanso kumapangitsanso kukana kwake kutentha kwapamwamba, ndipo kumatha kugwiritsidwa ntchito ngati zida zothana ndi kutentha kwambiri zolimbana ndi dzimbiri.
2. Nano silicon nitride (Si3N4)
2.1.Kupanga zida za ceramic zokhazikika.
2.2.Pamwamba mankhwala zitsulo ndi zipangizo zina.
2.3.Amagwiritsidwa ntchito ngati chosinthira kuti apititse patsogolo magwiridwe antchito a rabara wosagwirizana kwambiri.
2.4.Ma nanopowder opangidwa ndi silicon amatha kupititsa patsogolo mphamvu yamagetsi ya nayiloni ndi poliyesitala.
2.5.Nano silicon nitride kusinthidwa pulasitiki kuwala chingwe reel.
3. Nano titanium nitride (TiN)
3.1.Nano titanium nitride m'mabotolo onyamula a PET ndi zida zamapulasitiki
a.Kuchepetsa kutentha kwa thermoplastic akamaumba ndikupulumutsa mphamvu ndi 30%.
b.Mthunzi kuwala kwachikasu, kusintha kuwala ndi kuwonekera kwa mankhwala.
c.Wonjezerani kutentha kwa kutentha kuti mudzaze mosavuta.
3.2.Sinthani magwiridwe antchito a PET engineering mapulasitiki.
3.3.Chophimba chapamwamba chotenthetsera mpweya chimagwiritsidwa ntchito m'ng'anjo zotentha kwambiri ndi ma kilns populumutsa mphamvu ndi mafakitale ankhondo.
3.4.Titanium nitride yosinthidwa nsalu yogwira ntchito.
4. Nano titanium carbide (TiC)
4.1.Amagwiritsidwa ntchito kwambiri popanga zinthu zosavala, zida zodulira, nkhungu, zitsulo zosungunulira zitsulo ndi zina zambiri.
4.2.Kuuma kwa nano titanium carbide (TiC) ndikufanana ndi diamondi yokumba, yomwe imathandizira kwambiri kugaya bwino, kupukuta molondola komanso kutha kwa pamwamba.
4.3.zitsulo zokutira pamwamba.
5. Nano-zirconia/zirconium dioxide (ZrO2)
ZrO2 nano ufa ndi chinthu chofunikira kwambiri pokonzekera zitsulo zadothi zapadera, zomwe zingagwiritsidwe ntchito pokonzekera zoumba zosiyanasiyana zamapangidwe ndi ntchito.
5.1.Kusintha kwa gawo kumalimbitsa zoumba
Kuwonongeka kwa zida za ceramic kumachepetsa kukula kwake, ndipo nano ceramics ndi njira yofunika kwambiri yothetsera vutoli.Zoyeserera zikuwonetsa kuti zida zadothi zitha kulimba pogwiritsa ntchito ZrO2 tetragonal gawo mpaka gawo la monoclinic kuti apange ma microcracks ndi kupsinjika kotsalira.Kutentha kwa kusintha kumatha kutsika pansi pa kutentha kwa chipinda pamene tinthu ta ZrO2 tili pa nanoscale.Chifukwa chake, nano ZrO2 imatha kusintha kwambiri kutentha kwachipinda komanso kupsinjika kwambiri kwazoumba, potero kuchulukitsa kulimba kwa zoumba.
5.2.Ma ceramics abwino
Nano zirconia imatha kusintha kwambiri kutentha kwa chipinda ndi kupsinjika kwamphamvu kwa zoumba, potero kuchulukitsa kulimba kwa zoumba.Zophatikizika za bioceramic zokonzedwa ndi nano ZrO2 zili ndi makina abwino, kukhazikika kwamankhwala komanso kuyanjana kwachilengedwe, ndipo ndi mtundu wazinthu zophatikizika za bioceramic zomwe zikuyembekezeka kugwiritsa ntchito kwambiri.
5.3.Wotsutsa
Zirconia ili ndi malo osungunuka kwambiri, otsika matenthedwe matenthedwe komanso zinthu zokhazikika za mankhwala, choncho nthawi zambiri amagwiritsidwa ntchito ngati zinthu zotsutsa.Ubwino wa zinthu zodzitchinjiriza zokonzedwa ndi nano zirconia ndizofunika kwambiri, monga kukana kutentha kwambiri (kutentha kogwiritsa ntchito kumatha kufika 2200 ℃), mphamvu yayikulu, ntchito yabwino yotchinjiriza kutentha komanso kukhazikika bwino kwamankhwala, ndipo imagwiritsidwa ntchito makamaka m'malo ogwirira ntchito. kutentha pamwamba pa 2000 ℃.
5.4.Zosamva kuvala
Kuonjezera 5% nano scale Al2O3 ufa pazitsulo wamba wa Al2O3 kumatha kupititsa patsogolo kulimba kwa zoumba ndi kuchepetsa kutentha kwa sintering.Chifukwa cha superplasticity ya nano-Al2O3 ufa, imathetsa zofooka za brittleness yotsika kutentha yomwe imachepetsa ntchito yake, choncho imagwiritsidwa ntchito kwambiri muzitsulo zotsika kwambiri za alumina za pulasitiki.Itha kugwiritsidwa ntchito ku ziwiya zadothi zogwira ntchito, zoumba, zomangira zowonekera, zadothi za nsalu.
Nano zinc oxide ndi chinthu chofunikira kwambiri cha ceramic chemical flux, makamaka pomanga khoma la ceramic ndi glaze ya pansi komanso kutentha kwa maginito.
Amagwiritsidwa ntchito ngati flux, opacifier, crystallizer, ceramic pigment, etc.
