Vim nws qhov kev ua piv txwv, gaseous nitrogen tuaj yeem siv ntau yam ntawm kev ntxuav tawm, npog thiab yaug cov haujlwm. Ua raws li cov txheej txheem kev koom tes nrog, cov kev cai nitrogen purity yuav tsum tau ua kom tau raws li cov kev lag luam tsis sib xws.
Dab tsi yog nitrogen purity?
Nitrogen purity yog qhov feem pua ntawm cov nitrogen tam sim no hauv cov qauv coj los ntawm nws cov kwj nrog cov impurities tam sim no. Nitrogen tuaj yeem raug cais raws li cov pa roj siab lossis qis ntawm cov pa roj ua paug xws li oxygen, dej vapor, carbon monoxide thiab carbon dioxide.
Qhov kev faib tawm no raws li Nitrogen concentration lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov kev haum xeeb ntawm nitrogen rau txhua yam txheej txheem kev siv.
Muaj Siab Huv Huv vs. Qis Purity Nitrogen
Lub purity ntawm cov qauv nitrogen yog txiav txim siab los ntawm feem pua / concentration ntawm ntshiab nitrogen hauv nws. Rau cov roj av tau catalorized ua kom muaj siab, nws yuav tsum muaj tsawg kawg 99.998% Nitrogen suav nrog feem pua ntawm cov impurities ntau dua.
Siab purity nitrogen
Gaseous nitrogen nrog lub siab zoo saum 99.998% yog suav tias yog feem siab curaction. Cov Purity High Nitrogen tuaj yeem tau qhab nia sib txawv ntawm cov kev sib txawv los ntawm cov chaw tsim khoom sib txawv, tab sis lawv feem ntau txiav txim siab "PES TSO LOULTIONS. Xoom-qib high high-purity nitrogen yog categorized raws li xws li vim tias lawv muaj cov hydrocarbon impurities tsawg dua 0.5 feem ib lab.
Lwm cov yam ntxwv tseem ceeb ntawm kev purity siab nitrogen yog:
Cov pa oxygen ≤ 0.5 ppm
Carbon Monoxide / carbon dioxide tsis ntau tshaj li 1.0 ppm
Ya raws tsis loj tshaj 3 ppm
Qus purity nitrogen
Nitrogen nrog kev ua kom huv ntawm 90% kom tsawg dua 99.9% yog suav tias yog qis huv.
Nitrogen purity qhia
Qhov kev faib tawm ntawm cov nitrogen yog ua tiav los ntawm kev muab qhab nias uas siv cov lej nyob hauv txhua qib qis dua. Thawj tus lej ntawm txhua qib ntawm txhua tus lej yog hais txog tus naj npawb ntawm "nines" uas tshwm nyob rau hauv nws, thaum tus lej thib ob sawv cev tus lej tom qab cuaj tus lej kawg.
Cov qib kev ua purity ntawm nitrogen tau categorized li n2.0, n3.0, n6.0.
Dab tsi yog ultra-siab purity nitrogen?
UltraAUH-Purity Nitrogen yog nitrogen nrog kev xav ntawm 99.999% thiab negligible impurities. Nitrogen specifications yog nruj thiab hloov pauv kev cuam tshuam qhov kev faib tawm.
Cov pa roj yuav tsum tsis muaj ntau tshaj ob feem ib lab los ntawm ntim (ppmv) ntawm cov pa, 0.5 feem ib lab los ntawm kev ntim ntawm tag nrho cov lab los ntawm kev ntim ntawm noo noo). Nitrogen feem ntau yog siv rau kev siv cov ntaub ntawv science.
Cov pa oxygen pub dawb yog dab tsi?
Oxygen Dawb Nitrogen (ONN) yog txhais tias yog gaseous nitrogen uas tsis muaj ntau tshaj 0.5 ntu ib lab (ppm) ntawm cov pa. ONNOR gases yog feem ntau tswj hwm ntawm 99.998% kev coj dawb huv. Cov qib no yog siv hauv kev tshawb fawb thiab kev ntsuas hluav taws xob uas cov pa hluav taws xob yuav hloov qhov tshwm sim lossis ua rau muaj txiaj ntsig hloov.
Cov theem nitrogen purity los ntawm kev lag luam / ntawv thov
Raws li tau hais los saum no, cov concentration ntawm nitrogen yuav tsum rau cov txheej txheem sib txawv txawv heev. Qhov tseem ceeb hauv kev xaiv ib qib Nitrogen yog cov txiaj ntsig ntawm kev ua haujlwm ntawm cov ntawv thov xaiv. Kev rhiab heev rau ya raws, oxygen thiab lwm yam cov dej paug yog qhov tseem ceeb los txiav txim siab.
Khoom Noj Khoom Haus Qib Nitrogen / Haus Qib Nitrogen
Nitrogen feem ntau yog siv nyob rau hauv cov kauj ruam sib txawv ntawm cov zaub mov / dej ntau lawm, ntim thiab khaws cia. Nitrogen hauv ntim zaub mov thiab kev siv los tswj hwm lub txee rau cov khoom noj / dej haus los ntawm kev tshem tawm cov zaub mov oxidants, khaws cov tsw thiab tiv thaiv rancidity. Qhov kev coj dawb huv yuav tsum muaj rau cov khoom lag luam qib Nitrogen yog feem ntau nyob hauv cov 98-99.5%.
Kws Tshuaj Ntsuam Xyuas Cov Duab Nitrogen
Kws tsim khoom lag luam tsim nyog yuav tsum tau ua kom tsis txhob muaj kev sib kis thiab kev hloov ntawm cov khoom kawg. Ntau cov tshuaj kiab kiab tshuaj yuav tsum muaj qib siab nitrogen nrog cov nkauj ntawm 97-99.99%. Qhov no siab rau ultra-siab purity nitrogen yog siv los npog cov tso tsheb hlau luam nitrogen, ntim khoom thiab lwm yam tshuaj siv tshuaj.
Cov Purity High Nitrogen tseem siv nyob rau hauv cov chaw muag tshuaj kom pab tswj cov tshiab thiab tiv thaiv kev cuam tshuam ntawm cov khoom xyaw nquag.
Cov pa roj mitrogen nrog 95-99% kev coj dawb huv yog siv hauv cov roj thiab roj kev lag luam kom txo qis kev pheej hmoo ntawm hluav taws thiab tawg thaum lub sij hawm. Inerert tshuaj tso tsheb hlau luam thiab pipelines nrog gipelines nrog geterous nitrogen pab txo qis kev pheej hmoo ntawm lawv cov ntsiab lus.
Cov kev saib xyuas kev nyab xeeb feem ntau siv cov nitrogen nitrogen rau cov raj xa dej thiab cov raj xa hluav taws xob txiav txim siab.
Kev lag luam nitrogen qib kawm
Qee cov ntawv thov kev lag luam thiab lawv cov kev xav tau nitrogen tau teev tseg hauv qab no.
Electronics thiab semiconductor manufacturing qib nitrogen
Raug nitrogen cov kev xav tau hauv electronics thiab semiconductor raug yog feem ntau yog 99.99-99%. Qee cov txheej txheem xws li cov kev pab tu thiab cov kev pab txhawb nqa cov nplaum siv qis dua ntawm nitrogen (95-99.5%).
Plastics manufacturing qib nitrogen
Nitrogen qib yuav tsum tau rau cov xwm txheej plastics yog 95-98% rau kev txhaj tshuaj moulding, thiab 98-99.5% rau Blown zaj duab xis extrusion.
Hlau Ua Qib Nitrogen
Cov ntsiab lus nitrogen ntawm kev ua haujlwm qib hlau tau sib txawv heev, txij 95-99% rau kev kho cua sov rau 99-999% rau cov txheej txheem laser txiav.
Lub zog tiam nitrogen
Nitrogen hauv 95-99.6% ntau npaum li cas rau cov txheej txheem hluav taws xob cov txheej txheem, boiler ob sab, ntuj tso dej pipeline blowdown thiab dej softening overlay.
