High purity rhenium metal powder ndi ufa wachitsulo wonyezimira wopangidwa kuchokera ku makhiristo amodzi. Timatsimikizira kuti katundu wathu ali ndi chiyero chapamwamba, kukhazikika, ndi khalidwe lovomerezeka. Ufa wachitsulo wa Rhenium ukhoza kugwiritsidwa ntchito pazinthu zomwe zatha, monga mbale za anode zomwe zimagwiritsidwa ntchito pazachipatala. Chitsulo cha Rhenium ndi cholimba kwambiri, sichimva kuvala, sichikhala ndi dzimbiri, ndipo chimakhala ndi maonekedwe ofanana ndi platinamu. Rhenium yoyera ndi yofewa ndipo imakhala ndi makina abwino. Rhenium ili ndi malo osungunuka a 3180 ℃, yomwe ili pachitatu pakati pa zinthu zonse pambuyo pa tungsten ndi carbon. Kuwira kwake ndi 5627 ℃, kuyika koyamba pakati pa zinthu zonse. Imasungunuka mu nitric acid kapena hydrogen peroxide solution ndipo imasungunuka mu hydrochloric acid ndi hydrofluoric acid. Rhenium, ngati chitsulo chosowa chogwiritsa ntchito mwapadera, imagwira ntchito yosasinthika muzitsulo zotentha kwambiri zama injini zamlengalenga. Rhenium imagwiritsidwa ntchito popanga ma aloyi amtundu umodzi wotentha kwambiri wa kristalo ndipo amagwiritsidwa ntchito pamasamba a injini zakuthambo. Ndikofunikira njira zatsopano zothandizira. Rhenium imakhala yokhazikika pakatentha kwambiri, imakhala ndi mphamvu yotsika ya nthunzi, kukana kuvala, komanso kukana kuwononga kwa arc, ndikupangitsa kuti ikhale chinthu chabwino kwambiri choyeretsera zolumikizira zamagetsi.
Ntchito:
Amagwiritsidwa ntchito ngati chowonjezera cha rhenium high-temperature alloys, zokutira pamwamba pa injini za rocket ndi injini za satana, zida za atomiki, matenthedwe a ionization mass spectrometer, ufa wopopera.
Mankhwala a Rhenium monga ma rhenium granules, rhenium strips, rhenium plates, rhenium rod, rhenium foil, ndi mawaya a rhenium ndizo zida zoyambira.
Kufotokozera kwa Chemical:
Re-standard≥99.99%(Yowerengedwa ndi njira yochotsera,kupatula zinthu za gasi)Re-ultrapure≥99.999%(Yowerengedwa ndi njira yochepetsera,kupatula zinthu zamagesi)oxygen: ≤600ppm
Tinthu kukula: -200 mauna, D50 20-30um kapena malinga ndi zofuna kasitomala kupereka laser tinthu kukula kugawa mayeso lipoti kapena SEM zithunzi monga pa pempho kasitomala.
Kusanthula kwachilengedwe kwamankhwala
