Txhais thiab Purity Standards ntawm High-PurityMethane

High-puritymethanehais txog cov roj methane nrog lub siab purity. Feem ntau, methane nrog purity ntawm 99.99% lossis siab dua tuaj yeem suav tias yog siab purity.methane. Hauv qee qhov kev siv nruj dua, xws li kev lag luam hluav taws xob, kev xav tau purity yuav ncav cuag 99.999% lossis siab dua. Qhov no purity siab yog ua tiav los ntawm complex gas purification thiab sib cais technologies kom tshem tawm impurities xws li ya raws, carbon dioxide, carbon monoxide, hydrogen, thiab lwm yam gaseous Cheebtsam.

Siv thaj chaw ntawm high-purity methane

Hauv kev lag luam electronics,high-purity methaneyog siv los ua etching gas thiab raw khoom rau tshuaj vapor deposition (CVD) hauv semiconductor manufacturing. Piv txwv li, nyob rau hauv plasma etching, methane yog tov nrog lwm cov pa roj rau precisely etch semiconductor cov ntaub ntawv, tsim me me Circuit Court qauv. Hauv CVD,methanemuab cov pa roj carbon ntau rau kev loj hlob ntawm cov pa roj carbon monoxide, xws li silicon carbide films, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm cov khoom siv semiconductor.

Chemical Raw Khoom:High-purity methaneyog ib qho tseem ceeb raw khoom rau cov synthesis ntawm ntau cov khoom muaj nqi-ntxiv tshuaj. Piv txwv li, nws tuaj yeem cuam tshuam nrog cov tshuaj chlorine los tsim cov tshuaj chloromethane xws li chloroform, dichloromethane, trichloromethane, thiab carbon tetrachloride. Chloromethane yog cov khoom siv raw rau kev tsim cov organosilicon tebchaw, dichloromethane thiab trichloromethane feem ntau yog siv los ua cov kuab tshuaj, thiab carbon tetrachloride yog ib zaug siv los ua cov tua hluav taws, tab sis tam sim no kev siv yog nruj me ntsis txwv vim nws cov teebmeem ozone-depleting. Tsis tas li ntawd,methanetuaj yeem hloov mus rau hauv syngas (kev sib xyaw ntawm carbon monoxide thiab hydrogen) los ntawm kev hloov pauv cov tshuaj tiv thaiv, thiab syngas yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj methanol, hluavtaws ammonia, thiab ntau lwm yam khoom siv tshuaj.

Nyob rau hauv lub zog sector: Thaum uas muaj methane (natural gas) yog thawj lub zog,high-purity methanekuj plays lub luag hauj lwm nyob rau hauv tej yam tshwj xeeb kev siv zog. Piv txwv li, nyob rau hauv cov roj hlwb, high-purity methane tuaj yeem siv los ua roj, tab tom hloov kho kom tsim cov hydrogen, uas ua rau cov roj cell. Piv nrog rau cov fossil fuels ib txwm muaj, cov roj hlwb siv high-purity methane ua kom muaj zog ntau dua thiab qis dua cov pa phem.

Kev npaj cov pa roj carbon monoxide:High-purity methanetuaj yeem siv los ua tus qauv roj rau kev ntsuas cov ntsuas roj ntsuas. Piv txwv li, hauv cov roj chromatograph, sivhigh-purity methanecov pa roj carbon monoxide uas paub tias muaj peev xwm ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov siab thiab qhov tseeb, kom ntseeg tau qhov tseeb thiab txhim khu kev qha cov txiaj ntsig rau lwm cov pa roj.
