Nta & Qhov Zoo
Ultra- Tsawg Cov Kab Mob Sib Kis
Qhov tseem ceeb rau cov txheej txheem uas taug qab cov pa oxygen, noo noo, lossis hydrocarbons tuaj yeem ua rau muaj qhov tsis xws luag, oxidation, lossis catalyst lom, ua kom muaj txiaj ntsig zoo thiab cov khoom zoo.
Versatile Txo Atmosphere
Muab qhov zoo txo qhov chaw hauv metallurgy thiab cov ntaub ntawv ua, tiv thaiv oxidation thiab ua kom muaj kev kho cua sov zoo.
Tseem ceeb rau Zog thiab Electronics
Ua haujlwm raws li ob qho tib si cov khoom noj khoom haus hauv kev tsim khoom siv hluav taws xob thiab lub zog huv rau cov roj hlwb, txhawb kev txhim kho thev naus laus zis thiab decarbonization.
Cov khoom sib xws thiab ntseeg tau
Guaranteed purity thiab ruaj khov khoom chains yog qhov tseem ceeb rau kev ua haujlwm tas mus li hauv semiconductor fabs, tshuaj nroj tsuag, thiab chaw tshawb fawb.
Cov yam ntxwv ua haujlwm
Hydrogen standard gas functions feem ntau yog ib tug txo tus neeg sawv cev, cab kuj gas, los yog roj. Nyob rau hauv semiconductor manufacturing, nws yog siv nyob rau hauv annealing, epitaxial loj hlob, thiab raws li ib tug tsim gas (sib tov nrog nitrogen) los tiv thaiv oxidation. Nws cov thermal conductivity siab thiab tsawg ntom ua rau nws ua kom muaj cua txias nruab nrab hauv cov tshuab hluav taws xob loj. Hauv cov roj hlwb, nws electrochemically ua ke nrog oxygen los tsim hluav taws xob thiab dej. Rau cov txheej txheem tshuaj, nws koom nrog hydrogenation, hydrocracking, thiab desulfurization cov tshuaj tiv thaiv. Kev khaws cia tshwj xeeb, tuav, thiab ntxuav cov thev naus laus zis tau ua haujlwm los tswj nws cov purity los ntawm ib tiam mus rau qhov chaw siv.
Thawj daim ntawv thov teb

Cov neeg siv khoom sib koom tes Case
Lub tuam txhab ua lag luam ntawm cov khoom siv hluav taws xob siab tshaj plaws rau 5G cov khoom siv tau ntsib cov oxide txheej tsis sib xws thaum lub sij hawm tseem ceeb annealing kauj ruam, cuam tshuam rau transistor kev ua tau zoo thiab tawm los. Lawv xav tias cov pa oxygen hauv lawv cov txheej txheem roj yog tus ua txhaum. Peb koom tes nrog kev xa cov khoom siv siab ntawm 99.9999% siab purity hydrogen, kev koom ua ke nrog cov ntsiab lus - ntawm - siv purifier kom lav cov pa oxygen qis dua 10 ppb ntawm lub cuab yeej inlet.
