Thaum nws los txog rau n-butane, feem ntau tib neeg cov tshuaj tiv thaiv thawj zaug tseem nyob nrog cov roj sib zog lossis cov tshuaj polyurethane tshuab. Tab sis cov no yog tag nrho cov "cov ntaub ntawv nyoos" nrog purities ntawm 95% -99%. Thaum lub purity hla qhov pib ntawm 99.99% (4N) lossis txawm nce mus txog 99.999% (5N), siab -purity n-butane tag nrho tawm tom qab qis-kawg kev ua si ntawm cov tshuaj ib txwm muaj thiab hloov mus rau hauv ib qho "khoom noj khoom haus zoo" cov khoom lag luam zoo tshaj plaws hauv cov khoom lag luam thiab cov khoom lag luam zoo tshaj plaws hauv cov khoom lag luam. chav kuaj. Niaj hnub no, peb yuav soj ntsuam tob txog lub luag haujlwm uas tsis tuaj yeem hloov pauv tau uas siab -purity n-butane ua si hauv peb qhov kev xav tau ntawm cov roj hluav taws xob tshwj xeeb, cov roj hluav taws xob, thiab ntsuas ntsuas ntsuas qhov tseeb.
Raws li cov khoom siv hluav taws xob tshwj xeeb, tus nqi tseem ceeb ntawm High-Purity n-Butane Lies hauv Kev Muab Oxygen kiag li-dawb thiab Sulfur-Dawb Carbon Source rau Semiconductor Thin Film Processes. Ib qho ppb-Level Impurity yuav ua rau muaj kev puas tsuaj loj poob hauv Wafer tawm los.
Hauv cov tshuaj vapor deposition (CVD) thiab plasma etching txheej txheem ntawm chip manufacturing, siab -purity n-butane feem ntau yog siv los ua cov pa loj hlob rau silicon carbide films lossis carbon-doped silicon oxide. Tsis txhob xav tias koj tuaj yeem ntxuav tsuas yog muaj- qib n-butane thiab muab tso rau hauv lub tshuab. Chip fabs muaj qhov "zero" kam rau impurities.
Raws li SEMI (Semiconductor Equipment and Materials International) cov qauv, txawm tias ob peb ppb (ib feem ntawm ib billion) ntawm cov pa oxygen lossis ya raws hauv hluav taws xob -qib n-butane yuav tsim cov amorphous oxide txheej ntawm wafer nto, ua rau cov cuab yeej to. Cov txiaj ntsig ntawm sulfides yuav ua rau lom tag nrho cov khoom siv hlau muaj txiaj ntsig hauv CVD rauv tube, ua rau tag nrho cov wafers tsis muaj txiaj ntsig. Cia peb saib qhov sib txawv loj ntawm qib industrial thiab qib hluav taws xob:
| Core Parameter Indicator | Qib Industrial n{0}}Butane (Foaming/Fuel Use) | Electronic Speciality Gas Qib Siab -Purity n-Butane (SEMI Standard) | Kev puas tsuaj ntawm impurities ntawm cov txheej txheem semiconductor |
|---|---|---|---|
| Main Component Purity | Ntau dua lossis sib npaug li 95.0% | Ntau dua lossis sib npaug rau 99.999% (5N) | Tsis txaus purity ncaj qha ua rau cov zaj duab xis tuab tsis sib xws thiab tsis tswj cov etching tus nqi. |
| Cov ntsiab lus Oxygen / Argon | Tsis tswj nruj heev | Tsawg dua lossis sib npaug li 1.0 ppm | Cov pa oxygen impurities tsim oxide tsis xws luag ntawm qhov kub thiab txias, rhuav tshem cov khoom siv hluav taws xob thiab lub xeev kev sib tshuam. |
| Cov ntsiab lus noo noo | Typically >50 ppm | Tsawg dua lossis sib npaug li 1.0 ppm | Moisture ua rau lub tshuab nqus tsev vacuum distortion, ua rau cov kab mob sib kis thiab txo cov zaj duab xis adhesion. |
| Tag nrho cov ntsiab lus Sulfur | Typically >5ppm ua | Tsawg dua los yog sib npaug li 0.5 ppm | Sulfur yog "tus huab tais ntawm cov tshuaj lom catalyst," ncaj qha ua rau cov yeeb yaj kiab loj hlob stagnation thiab crystal qauv distortion. |
Hauv Teb Chaws Cov Khoom Siv Hluav Taws Xob, High-Purity n-Butane yog qhov tsim nyog rau Kev Npaj VOCs Saib Xyuas Cov Qauv Roj thiab FID Ntes Roj Roj. Nws Purity ncaj qha txiav txim siab raws txoj cai ntawm Environmental Monitoring Data.
Cov kws ua haujlwm ua haujlwm hauv kev saib xyuas ib puag ncig thiab kev tshawb nrhiav roj av petrochemical paub tias cov nplaim hluav taws xob ionization ntes (FID) hauv cov roj chromatographs tsis tshua muaj siab rau hydrocarbons. High-purity n-butane, vim nws cov pa roj carbon tsawg thiab kev sib txuas ruaj khov, feem ntau yog siv los ua cov pa roj carbon monoxide rau FID thiab tseem yog lub hauv paus tseem ceeb rau kev npaj cov tshuaj tsis haum tshuaj organic (VOCs) cov qauv gases.
Raws li qhov yuav tsum tau muaj nyob rau hauv cov qauv xws li "Ambient Air - Kev txiav txim siab ntawm Volatile Organic Compounds" (HJ 759-2023), cov pa roj carbon monoxide yuav tsum xyuas kom meej meej. Yog tias cov n-butane hauv cov pa roj carbon monoxide tsis huv thiab muaj cov tshuaj tsw qab los yog olefins, FID detector yuav tsim "dab peaks" los yog lub hauv paus loj drift. Qhov no zoo li siv tus pas ntsuas nrog cov cim tsis raug los ntsuas cov khoom. Qhov kawg suav VOCs emission concentration yuav ua tsis ncaj ncees lawm, tsis tsuas yog ua tsis tiav kev ntsuam xyuas ib puag ncig tab sis kuj yuav ua rau muaj kev nplua nyiaj ntau los ntawm cov koom haum tiv thaiv ib puag ncig.
Nyob rau hauv Precision Instrument Calibration, High-Purity n-Butane, los ntawm Kev Tsim Nyog ntawm Nws Lub Sijhawm ruaj khov heev thiab Cov Qauv Loj Spectral Fragmentation, ua haujlwm raws li Benchmark Tshuaj rau GC-MS Calibration thiab Tuning.
Cov cuab yeej tshuaj ntsuam xyuas drift dhau sijhawm thiab yuav tsum tsis tu ncua "nqa rov qab mus" nrog cov khoom paub. High-purity n-butane muaj lub sij hawm zoo heev thiab ruaj khov nyob rau hauv cov roj chromatography, ua rau nws tus qauv zoo meej rau kev txheeb xyuas chromatographic kem sib cais efficiency thiab ntsuas rhiab heev.
Nyob rau hauv huab hwm coj spectrometry tuning, qhov loj spectral fragmentation qauv ntawm n-butane (tus yam ntxwv fragment peaks m/z 43, 57, thiab lwm yam) yog tsis tu ncua. Siv siab -purity n-butane rau huab hwm coj axis calibration kom paub meej qhov hnyav molecular txiav txim ntawm cov qauv tsis paub. Txawm li cas los xij, muaj qhov yuav tsum tau ua kom tuag taus: yog tias n-butane muaj isomers (isobutane), vim lawv lub sijhawm khaws cia ze heev, nws yuav ua rau chromatographic ncov sib tshooj thiab ua haujlwm, ua rau tag nrho cov ntaub ntawv zoo thiab muaj nuj nqis hauv tag nrho cov chaw kuaj mob tsis raug.
Cov Kev Xav Tau Tshwj Xeeb ntawm Siab -End Applications Force the Ultimate Upgrade of Source Purification Technology. Raws li ib tug kws tsim khoom ntawm n-Butane, ZL Zog Siv Ultra-Distillation Technology los hla lub neej-thiab-Txoj kab tuag ntawm kab tsis zoo.
Txawm hais tias nws yog cov roj hluav taws xob tshwj xeeb, cov roj hluav taws xob, lossis cov ntsuas ntsuas ntsuas, qhov mob tseem ceeb tag nrho los rau ib lo lus - "purity." Muaj ntau lub tuam txhab tsim khoom lag luam uas tuaj yeem tsim n-butane nrog 99% purity, tab sis tsawg heev tuaj yeem xa cov khoom loj 4N/5N siab-purity n-butane. Qhov no yog vim kev sib cais tag nrho n-butane los ntawm isobutane, uas txawv ntawm qhov kub ntawm tsuas yog 0.6 degree, thiab tshem tawm sulfides zais tob hauv C4 qauv, yuav tsum muaj kev cuam tshuam tsis zoo.
Qhov no yog qhov tseeb ZL Energy tus thawj tswj hwm. Raws li ib tug kws manufacturers ntawmn-Butane, ZL Energy nkag siab tob txog qhov mob ntawm cov neeg siv khoom siab - kawg. Ntau dua li ua txoj hauv kev qis - xaus kev nthuav dav, nws tsom mus rau kev sib cais qhov tseeb. Los ntawm kev qhia siab -kev ua tau zoo distillation units nrog ntau pua lub tais thiab ntau yam -theem desulfurization thiab lub cev qhuav dej, ZL Zog tuaj yeem "rub tawm los ntawm cov hauv paus hniav" isobutane, olefins, thiab cov kab ntau ntawm cov dej, sulfur, thiab oxygen impurities los ntawm n-butane los yog purity, 5n qib. Xaiv ZL Zog txhais tau hais tias koj lub tshuab ntes FID tsis muaj teeb meem los ntawm dab peaks lawm, koj GC-MS lub sij hawm tuav tsis txhob ya mus lawm, thiab koj lub semiconductor CVD rauv tubes tsis muaj paug los ntawm impurities lawm. Cia lub peev xwm tswj tau zoo ntawm cov chaw tsim khoom lag luam tiv thaiv koj cov ntawv thov siab - kawg.
