Kugwiritsa ntchito kwa nano lanthanum oxide mumafuta opaka mafuta
Pamene chiwerengero chapamwamba cha PB chopanda khadi chamtengo wapatali cha mafuta opangira mafuta ndi 362N, kutalika kwa malo opera ndi 0.720mm, ndipo friction factor ndi 0.1240, particles nano-La2O3 zimawonjezeredwa, ndipo mtengo wa PB umawonjezeka gawo lalikulu la nanoparticles limawonjezeka. Mtengo wapamwamba wa 510N umafika pamene gawo lalikulu ndi 0.4% -0.8%. Zomwe zili zazikulu kuposa 0.8%, mtengo wa PB umachepa. Dera la D ndi friction factor idafika pamlingo wochepera 0.454mm ndi 0.0881 pagawo lalikulu la 0.8%. Fanizoli likuwonetsa kuti kuwonjezera kwa tinthu tating'ono ta nano-La2O3 pamafuta oyambira kumatha kupititsa patsogolo ntchito yolimbana ndi kuvala komanso kuchepetsa mikangano yamafuta opaka mafuta, ndipo kuchuluka kwabwinoko ndi 0.8%. Poyerekeza ndi mafuta apansi, mtengo wake wa PB unawonjezeka ndi 40.8%, m'mimba mwake mwa malo otsekemera unachepetsedwa ndi 36.9%, ndipo coefficient of friction inachepetsedwa ndi 29%.
Kusanthula kwamakina a nanoparticles ngati zowonjezera zowonjezera
(1) Njira yopukutira. Nano-La2O3 tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono titha kuchitapo kanthu "kupukuta"
(2) Njira yopukusa. Pamwamba pa mikangano iwiri, tinthu tating'onoting'ono ta nano-La2O3 timagwira ntchito "yokhala ndi yaying'ono", kuchepetsa mikangano ndikuwongolera kunyamula katundu.
(3) Kukonza makina. Tinthu tating'onoting'ono ta Nano-La2O3 titha kudzaza maenje ndikuchita nawo gawo pakudzaza ndi kukonza.
(4) Makina opanga mafilimu. Pansi pa kupsinjika kwamphamvu kwamphamvu, tinthu tating'onoting'ono ta nano-La2O3 tokhala ndi ntchito yayikulu kwambiri timakongoletsedwa ndi tinthu tating'onoting'ono, tikupanga filimu yoteteza, yomwe ingateteze kukangana pamwamba.
