- Kev Tshawb Fawb Hluav Taws Xob ntawm Rhenium (e {{{} g}! Siv Hauv Kev Tshawb Fawb Txog Kev Kho Mob (←nembolization).
Poov tshuaj Pertrhenate yog kev txob txob, zam kev sib cuag nrog cov tawv nqaij thiab cov tshuaj tua kab mob. Nws yuav tsum tau muab khaws cia rau hauv cov thawv ntim hauv qhuav, txias (<30°C) and isolated from flammables, reducing agents and acids to maintain stability.
Nws yog ib qho kev ua kom muaj txiaj ntsig zoo tshaj plaws rau nws lub luag haujlwm hauv cov roj av rhenium, ua ke nrog cov roj av rov qab los ntawm cov roj av rov qab los ntawm roj av engineering rau aerospace engineering {}}
Gneebioyog ib tug kws tshaj lij kev tsim khoom lag luam thiab cov neeg siv khoom thoob ntiaj teb, suav nrog kev sib xyaw ua ke, suav nrog kev sib xyaw, rov qab, thiab faib.
Peb liKub Muag Khoomsuav nrog cov ntxhiab hydrocarbons (naphtha (roj av), benzene,Toluene, O-XYYLENE, Styrene, Cyclohexane, Cyclohexanone, Epsilon-Caprolactam, 2-Anilinoethanol, etc.), alcohols (Ethylene Glycol, 1-Butanol, 2-Methyl-1-Propanol, Ethyl Alcohol, lwm yam {.}), cov phenols thiab cov ketylenone, ecafenone,}}), thiab petrochemicals.
