Kev ua tau zoo thiab ntseeg tau
Guaranteed purity ua kom cov txiaj ntsig tau rov ua dua tshiab hauv kev siv tshuaj ntsuam xyuas, kev ua haujlwm ruaj khov arc hauv vuam, thiab kev kwv yees tus cwj pwm hnyav hauv cov txheej txheem supercritical.
Ntau yam txheej txheem nruab nrab
Kev ua haujlwm tau zoo raws li cov kua dej supercritical, tiv thaiv roj, cryogenic coolant, thiab reagent, nrog rau nws cov purity siab ua kom siv tau rau hauv cov kev xav tau tshaj plaws.
Tseem ceeb rau Advanced Manufacturing
Qhov tseem ceeb rau cov txheej txheem uas impurity-vim qhov tsis xws luag yog qhov tsis txaus, xws li hauv laser txiav ntawm siab- cov hlau cuam tshuam lossis tsim cov fibers optical.
Cov yam ntxwv ua haujlwm
Cov pa roj carbon dioxide standard gas pab ntau yam kev ua haujlwm siab heev. Nyob rau hauv nws lub xeev supercritical (tshaj 31℃thiab 73.8 bar), nws dhau los ua lub zog muaj zog, tunable hnyav rau kev rho tawm thiab ntxuav, tsis muaj cov kuab tshuaj seem. Raws li ib tug shielding roj nyob rau hauv vuam (feem ntau tov nrog argon), nws stabilizes lub arc thiab cuam tshuam cov hlaws geometry, nrog purity yog ib qho tseem ceeb rau weld kev ncaj ncees ntawm reactive hlau. Hauv hluav taws xob, nws yog siv rau wafer txias thiab ua cov txheej txheem roj hauv qee qhov plasma etches. Nws inertness thiab tsis tshua muaj reactivity, ua ke nrog siab purity, ua rau nws haum rau daim pam thiab sparging rhiab tshuaj. Nws yog feem ntau ntxiv purified ntawm qhov chaw siv rau cov ntawv thov tseem ceeb tshaj plaws.
