Dab tsi yog cov tau ua tau zoo ntawm niobium screws?

Lub ntsiab lus melting ntawm Niobium yog siab npaum li 2996 degree, thiab nws qhov cub npau yog 4742 degree. Screws ua los ntawm niobium tuaj yeem tswj kev ruaj khov hauv ib puag ncig kub thiab tsis yooj yim deformed. Lawv tuaj yeem siv rau txuas siab siab - kub cov khoom siv xws li Dav Hlau Cav, Roj Turumines, Cov Khoom Siv Hluav Taws Xob, thiab lwm yam.
Qhov saum npoo ntawm Niobium tuaj yeem tsim cov yeeb yaj kiab dension oxide, uas muab nws cov kua roj acid acid, fuming sulfuric acid, nrog rau cov kev daws teeb meem alkaline ntawm ntau yam ntau. Yog li no, niobium screws yog qhov tsim rau kev xeb ib puag ncig xws li tshuaj lom neeg thiab cov chaw muaj dej hiav txwv.
Niobium muaj lub siab tensile modulus thiab hardness, uas ua rau screws nrog lub zog siab. Piv txwv li, tawv niobium screws muaj lub zog siab dua, uas tuaj yeem ua kom tau raws qee qhov kev ua kom nrawm dua rau cov khoom siv nrawm.
Cov uas muaj ntau yam uas muaj xws li ntawm niobium screws, xws li R04210 ntshiab niobium ntsia hlau; Tseem muaj niobium allloy screws. Peb muab ntau qhov ntau thiab tsawg, suav nrog cov kab uas hla sib txawv thiab cov kev xav tau raws li cov kev xav tau. Peb kuj tseem tuaj yeem tsim tsis yog- Txheem seem raws li cov neeg siv khoom kos duab thiab cov qauv.
Nws yog tsuas yog siv nyob rau hauv ib lub teb chaws aerospace xws li Aerospace tshuab thiab siv tau rau hauv cov ntawv thov kev ua haujlwm zoo xws li muaj cov khoom siv kub siab, thiab muaj kev kub taub hau kub thiab txias} - kub tshuab pwm.
