Umwuka wa Lutetiumni ibikoresho bitanga ibyangiritse bitewe nubushyuhe bwo hejuru, birwanya ruswa, nimbaraga nke za fononi.Byongeye kandi, kubera imiterere yabyo bahuje ibitsina, nta ntera ihindagurika iri munsi yumushonga, hamwe no kwihanganira imiterere ihanitse, igira uruhare runini mubikoresho bya catalitiki, ibikoresho bya magneti, ikirahure cya optique, laser, electronics, luminescence, superconductivity, hamwe nimirasire yingufu nyinshi gutahura.Ugereranije nuburyo gakondo bwibikoresho,lutetiumibikoresho bya fibre byerekana ibyiza nka ultra-strong flexible, kwangirika kwinshi kwa laser, no kwaguka kwagutse.Bafite ibyerekezo byinshi byo gukoresha mubice bya lazeri zingufu nyinshi nibikoresho byubushyuhe bwo hejuru.Nyamara, diameter ndendelutetiumfibre yabonetse muburyo gakondo akenshi iba nini (> 75 μ m) Ihinduka ni rito ugereranije, kandi nta raporo zigeze zerekana imikorere-yo hejurulutetiumfibre ikomeza.Kubera iyo mpamvu, Porofeseri Zhu Luyi n'abandi bo muri kaminuza ya Shandong bakoreshejelutetiumirimo polymers organic (PALu) nkibibanziriza, ifatanije no kuzunguruka byumye hamwe nuburyo bwo gutunganya ubushyuhe, kugirango icike icyuho cyo gutegura imbaraga-nini na diameter nziza ya lutetium oxyde ya fibre ikomeza, kandi igere ku myiteguro igenzurwa yimikorere ikomeye.lutetiumfibre ikomeza.
Igishushanyo 1 Inzira yumye yo gukomezalutetiumfibre
Uyu murimo wibanze ku kwangirika kwimiterere ya fibre prursor mugihe ceramic.Guhera kumabwiriza yuburyo bubora, hashyizweho uburyo bushya bwumuvuduko ufasha gufata imyuka y'amazi.Muguhindura ubushyuhe bwo kwitegura kugirango ukureho ligand organique muburyo bwa molekile, ibyangiritse kumiterere ya fibre mugihe cyibikorwa bya ceramic biririndwa cyane, bityo bikomeza gukomezalutetiumfibre.Kugaragaza ibintu byiza bya mashini.Ubushakashatsi bwerekanye ko ku bushyuhe buke mbere yo kuvurwa, ababanjirije bashobora guhura na hydrolysis, bigatera inkari ku busa kuri fibre, bigatuma habaho gucikamo ibice hejuru ya fibre ceramic na pulverisation itaziguye kurwego rwa macro;Ubushyuhe bwo hejuru mbere yo kuvura buzatera uwabanjirije gutondeka nezalutetium, bitera imiterere ya fibre itaringaniye, bivamo ubunini bwa fibre nuburebure bugufi;Nyuma yo kubanza kuvurwa kuri 145 ℃, imiterere ya fibre iba yuzuye kandi hejuru irasa neza.Nyuma yo kuvura ubushyuhe bwo hejuru, macroscopique hafi ya mucyo ikomezalutetiumfibre ifite diameter ya 40 yabonetse neza μ M.
Igishushanyo 2 Amafoto meza na SEM amashusho ya fibre prursor yakozwe mbere.Ubushyuhe bwo kubanziriza: (a, d, g) 135 ℃, (b, e, h) 145 ℃, (c, f, i) 155 ℃
Igishushanyo cya 3 Ifoto nziza yo gukomezalutetiumfibre nyuma yo kuvura ceramic.Ubushyuhe bwo kubanziriza: (a) 135 ℃, (b) 145 ℃
Igishushanyo 4: (a) Ikirangantego cya XRD, (b) amafoto ya microscope optique, (c) ituze ryumuriro na microstructure yo gukomezalutetiumfibre nyuma yo kuvura ubushyuhe bwo hejuru.Ubushyuhe bwo kuvura ubushyuhe: (d, g) 1100 ℃, (e, h) 1200 ℃, (f, i) 1300 ℃
Mubyongeyeho, iki gikorwa kiratanga raporo kunshuro yambere imbaraga zingana, modulus ya elastique, guhinduka, hamwe nubushyuhe bwo gukomezalutetiumfibre.Imbaraga imwe ya filament tensile ni 345.33-373.23 MPa, modulus ya elastique ni 27.71-31.55 GPa, na radiyo ihebuje ya radiyo ni mm 3,5-4.5.Ndetse na nyuma yo kuvura ubushyuhe kuri 1300 ℃, nta kugabanuka gukabije kwimiterere ya fibre, ibyo bikaba byerekana neza ko ubushyuhe bwubushyuhe bukomezalutetiumfibre yateguwe muriki gikorwa ntabwo iri munsi ya 1300 ℃.
Igicapo 5 Imiterere ya mashini yo gukomezalutetiumfibre.(a.Ubushyuhe bwo kuvura ubushyuhe: (d) 1100 ℃, (e) 1200 ℃, (f) 1300 ℃
Uyu murimo ntabwo uteza imbere gusa gusaba no guteza imberelutetiummubushyuhe bwubushyuhe bwo hejuru, ibikoresho byingufu nyinshi, nizindi nzego, ariko kandi bitanga ibitekerezo bishya byo gutegura okiside ikora cyane ya fibre ikomeza fibre
