Kugwiritsa ntchito nano cerium oxide mu polima

Nano-ceria imathandizira kukana kukalamba kwa ultraviolet kwa polima.

Mapangidwe amagetsi a 4f a nano-CeO2 amakhudzidwa kwambiri ndi kuyamwa kwa kuwala, ndipo gulu loyamwitsa limakhala makamaka m'chigawo cha ultraviolet (200-400nm), chomwe chilibe mayamwidwe owoneka bwino komanso kufalikira kwabwino. Wamba ultramicro CeO2 ntchito ultraviolet mayamwidwe kale ntchito mu galasi makampani: CeO2 ultramicro ufa ndi tinthu kukula zosakwana 100nm ali kwambiri ultraviolet mayamwidwe luso ndi kutchinga tingati angagwiritsidwe ntchito sunscreen CHIKWANGWANI, galimoto galasi, utoto, zodzoladzola, filimu, pulasitiki ndi nsalu, etc. Itha kugwiritsidwa ntchito panja poyera mankhwala kusintha kukana nyengo, makamaka mankhwala ndi mkulu transparency zofunikira monga mapulasitiki owonekera ndi ma varnish.

Nano-cerium oxide imathandizira kukhazikika kwamafuta a polima.

Chifukwa cha mawonekedwe apadera akunja akunja amagetsi osowa padziko lapansi, ma oxides osowa padziko lapansi monga CeO2 akhudza kukhazikika kwamafuta a ma polima ambiri, monga PP, PI, Ps, nayiloni 6, epoxy resin ndi SBR, zomwe zitha kusinthidwa ndikuwonjezera zosoweka zapadziko lapansi. Peng Yalan et al. adapeza kuti pophunzira mphamvu ya nano-CeO2 pa kukhazikika kwamafuta a methyl ethyl silikoni rabara (MVQ), Nano-CeO2 _2 mwachiwonekere amatha kusintha kutentha kwa mpweya kukana kukalamba kwa MVQ vulcanizate. Pamene mlingo wa nano-CeO2 ndi 2 phr, katundu wina wa MVQ vulcanizate alibe mphamvu zambiri pa ZUi, koma kukana kwake kutentha kwa ZUI ndikwabwino.

Nano-cerium okusayidi bwino madutsidwe wa polima

Kukhazikitsidwa kwa nano-CeO2 mu ma polima oyendetsa kutha kupititsa patsogolo zinthu zina zazinthu zopangira ma conductive, zomwe zimatha kugwiritsidwa ntchito pamakampani amagetsi. Ma polima a conductive ali ndi ntchito zambiri pazida zosiyanasiyana zamagetsi, monga mabatire omwe amatha kuchangidwa, masensa amankhwala ndi zina zotero. Polyaniline ndi imodzi mwa ma polima a conductive omwe amagwiritsidwa ntchito pafupipafupi. Kuti apititse patsogolo mphamvu zake zakuthupi ndi zamagetsi, monga madutsidwe amagetsi, maginito ndi ma photoelectronics, polyaniline nthawi zambiri imakhala yophatikizana ndi zigawo zina kuti apange nanocomposites. Liu F ndi ena adakonza zophatikizika zingapo za polyaniline/nano-CeO2 zokhala ndi milingo yosiyanasiyana ya molar ndi in-situ polymerization ndi doping hydrochloric acid. Chuang FY et al. okonzeka polyaniline / CeO2 nano-composite particles ndi pachimake-chipolopolo dongosolo, Iwo anapeza kuti madutsidwe wa gulu particles chinawonjezeka ndi kuwonjezeka kwa polyaniline / CeO2 molawirira chiŵerengero, ndi digiri ya protonation anafika za 48.52%. Nano-CeO2 ndiyothandizanso kwa ma polima ena oyendetsa. CeO2/ polypyrrole composites yokonzedwa ndi Galembeck A ndi AlvesO L amagwiritsidwa ntchito ngati zipangizo zamagetsi, ndipo Vijayakumar G ndi ena doped CeO2 nano mu vinylidene fluoride-hexafluoropropylene copolymer.
