Nano Graphene Ufa CAS 1034343-98-0 Mtengo wa Mafakitale a Batri
Mafotokozedwe Akatundu
Graphene oxide ili ndi magulu ambiri okhala ndi mpweya pamwamba pake. Ili ndi kusungunuka bwino kwa solvent komanso kugwirizana ndi ma polima. Kuchuluka kwa mpweya m'gulu la mpweya ndi 30-40%, kusungunuka kwa madzi ndi kwabwino kwambiri, ndipo kuchuluka kwa monolayer pambuyo pa kusungunuka ndi kopitilira 99%. Kukula ndi makulidwe a microchip kunali kuyambira 0.5 mpaka 3 um komanso kuyambira 0.55 mpaka 1.2 nm. Palibe mvula.
Ufa wa graphene oxide umapezeka poumitsa ndi vacuum cleaner wa graphene oxide sol. Pakuumitsa ndi kuzizira, graphene oxide sidzataya magulu okhala ndi mpweya pamwamba ndipo imayambitsa kusakanikirana pakati pa zigawo za graphene oxide. Ufawo ukauma umakhala ndi mabowo komanso ngati siponji. Umasungunuka mwachangu komanso kwathunthu ukawonjezera madzi, ndipo nthawi yomweyo umabwezeretsa mphamvu zoyambirira za sol.
Ufa wa graphene oxide ukhoza kufalikira mwachindunji mu yankho lamadzi ndi solvent (ultrasound ndi yabwino) kuti mupeze yankho lofanana komanso lokhazikika la kufalikira (onani buku lotsogolera kufalikira kwa njira yeniyeni yofalikira).

Kugwiritsa ntchito
Graphene ndi chinthu cha kaboni chokhala ndi magawo awiri chokhala ndi udzu wokhala ndi maatomu a kaboni ndi ma orbitals osakanizidwa a sp².
Graphene ili ndi mphamvu zabwino kwambiri zowunikira, zamagetsi, ndi makina, ndipo ili ndi mwayi wofunikira wogwiritsa ntchito mu sayansi ya zinthu, kukonza zinthu zazing'ono, mphamvu, biomedicine, ndi kupereka mankhwala. Imaonedwa kuti ndi chinthu chosintha kwambiri mtsogolo.
Njira zodziwika bwino zopangira ufa wa graphene ndi njira yochotsera utoto wa makina, njira ya redox, njira yokulira ya SiC epitaxial, ndipo njira yopangira filimu yopyapyala ndi chemical vapor deposition (CVD).
Kulongedza ndi Kusunga

Zovala zoyenera zodzitetezera ndi magolovesi oteteza ziyenera kuvalidwa kuti zisakhudze thupi la munthu mwachindunji. Ngati zakhudzana, kutsuka nthawi yomweyo ndi madzi ambiri ndikofunikira. Njira zoyenera zokonzera ziyenera kuchitidwa kuti fumbi lisatuluke. Onetsetsani kuti mpweya wabwino ukuyenda bwino ndikuyika zosonkhanitsa fumbi kuti mupewe kupuma. Samalani mukatsegula ndi kutsitsa kuti phukusi lisawonongeke.
Chogulitsacho chiyenera kusungidwa m'zidebe zotsekedwa bwino pamalo ouma, ozizira, komanso opumira bwino, kusunga mtunda wotetezeka kuchokera ku zinthu zoyatsira moto ndi kutentha. Chiyenera kulekanitsidwa ndi zinthu zochepetsera moto zamphamvu ndi zinthu zoyaka. Onetsetsani kuti mapaketiwo ali bwino komanso opanda madzi. Phukusi likatsegulidwa, chinthucho chiyenera kugwiritsidwa ntchito mwachangu. Mapaketi ogwiritsidwa ntchito pang'ono ayenera kutsekedwanso mwamphamvu. Chogulitsacho chimakhala chovuta ndi chinyezi. Ngati chinthucho chimatenga chinyezi, kaya chifukwa cha kuwonongeka kwa phukusi kapena kusungidwa kotseguka, tikukulimbikitsani kuti, mutachotsa phukusi lakunja (kupatula thumba la valavu ya pepala), chinthucho chiume pa 80°C kwa maola angapo mpaka chifike pamalo opanda chinyezi.
Malinga ndi zomwe zatchulidwa pamwambapa, mankhwalawa amakhalabe ogwira ntchito kwa nthawi yayitali. Ngati pali zofunikira kwambiri zokhudzana ndi chinyezi, ndibwino kuumitsa motsatira Article 5 musanagwiritse ntchito.
MAYENDEDWE
Katundu wosaletsedwa. Chitetezeni ku dzuwa, mvula, kutuluka kwa madzi ndi zilembo zobisika. Zoletsedwa kuponyedwa. Gwirani mosamala mukanyamula ndi kutsitsa kuti mupewe kuwonongeka. Sungani kutali ndi magwero oyatsira moto ndi kutentha. Musanyamule pamodzi ndi zinthu zowononga.
