I-Carbon fiber inezici zamandla aphezulu nesisindo esilula, futhi impahla eyinhlanganisela ene-polymer ifaneleka kakhulu kwi-aerospace, imboni yezimoto, ama-wind turbine blades kanye nempahla yezemidlalo.Kodwa-ke, izinto ezinjalo eziyinhlanganisela zizohluleka ngendlela eyinhlekelele ngaphandle kwesixwayiso, okufana nokuwa kwezitsha zobumba.
Muva nje, abacwaningi base-Oak Ridge National Laboratory kanye ne-Virginia Tech kanye ne-State University bathuthukise indlela futhi bayishicilela ku-Journal of Composites Science and Technology.Ngokungeza nje i-nano-TiO2, inganikeza isexwayiso sangaphambi kwesikhathi sokulahlekelwa ukusebenza kahle.
Izinto ezihlanganisiwe ze-carbon fibre composite, ikakhulukazi izinto eziyinhlanganisela ezisuselwe ku-epoxy resin, zijwayele ukuncipha lapho isibopho phakathi kwefayibha ne-matrix kwehluleka.Uma zingekho izimpawu eziyisixwayiso zangaphandle, kungase kwenzeke ukuphuka kungazelelwe, okukhawulela ukuba usizo kwalezi zinto eziyinhlanganisela ekusetshenzisweni kwesakhiwo.Abantu bahlola izindlela ezihlukene zokuqapha ubuqotho besakhiwo sezinhlanganisela ze-carbon fibre, njengokushumeka izinto ze-piezoresistive endabeni, okushintsha ukumelana nokucindezeleka.Izinto ze-piezoresistive zingaguqula ubunzima bemishini ibe amasignali kagesi, angatholwa yizinzwa ukuqapha impilo yesakhiwo sezinto ezihlanganisiwe.
Abacwaningi bashumeke i-TiO2I-Nano titanium dioxideama-nanoparticles embotsheni ye-polymer noma usayizi we-carbon fibers ukwenza impahla ye-piezoresistive isatshalaliswe ngokulinganayo kuyo yonke into eyinhlanganisela.Ukulinganisa kuvame ukusetshenziselwa i-carbonized carbon fiber, ukuze kube lula ukucutshungulwa nokusebenzisa nokuhlanganisa ne-matrix, futhi ekugcineni kusungulwe ikhono lokuzwa ubunzima kule nqubo.Lapho ukucindezela kuqedwa, ukumelana kungu-zero, futhi lapho ukucindezela kukhiqizwa, ukumelana kuyanda.Kunjalo, inani le-TiO2 nanoparticles elengeziwe lidinga ukulawulwa, ingxenye ephezulu kakhulu izonciphisa amandla ezinto eziyinhlanganisela, futhi ukwengeza okufanele kuzothuthukisa ukusebenza kokudambisa (ukumuncwa ukushaqeka nokusebenza kokuphazamisa) kwento.
Inkampani yaseHongwu ihlinzeka ngeNano titanium dioxide ngale ndlela elandelayo:
1. Anatase TiO2, usayizi 10nm, 30-50nm.99%+
2. Rutile TIO2, usayizi 10nm, 30-50nm, 100-200nm.99%+
Sicela uzizwe ukhululekile ukusithinta nganoma imiphi imibuzo.
