Hauv kev lag luam petrochemical thiab kws tshuaj, reactors feem ntau ua haujlwm nyob rau hauv cov xwm txheej hnyav ntawm ntau pua degrees Celsius thiab ntau ntau megapascals. Thaum cov xov xwm cuam tshuam nrog cov nplaim hluav taws thiab tawg, cov khoom siv kev nyab xeeb thiab kev ntseeg tau ncaj qha cuam tshuam rau kev lag luam txuas ntxiv. Hlau sintered ntxeem tau cov ntsiab lus, ua hauj lwm raws li ib tug tseem ceeb roj faib thiab kev nyab xeeb pab kiag li lawm, yog cov "invisible guardians" nyob rau hauv cov huab ua hauj lwm tej yam kev mob.
Cov Ntsiab Cai Ua Haujlwm: Precise Control ntawm Micro Pores
Hlau sintered ntxeem tau cov ntsiab lus yog tsim los siv high -kub sintering tshuab nyob rau hauv cov hmoov metallurgy: hlau hmoov (xws li 316L stainless hlau los yog Hastelloy) yog txias isostatically nias, ces metallurgically bonded ntawm high kub los tsim ib tug nruj monolithic qauv nrog peb -dimensional channel.
►Core Parameters thiab Performance Data

Porosity: 30-40% (ua kom pom tseeb permeability thaum tswj lub zog)
Gas Txoj Cai
Raws li cov pa roj dhau los ntawm cov micron - qhov pores loj, nws tau muab faib ua suav tsis txheeb micro- npuas, ua kom muaj txiaj ntsig zoo ntawm cov tshuaj tiv thaiv tawm. Nrog 10 μm pore ntsiab:
Npuas txoj kab uas hla: ≈ 50-200 μm (cov khoom lag luam ib txwm tsim npuas > 2 hli)
Gas-liquid contact area: 10–20 zaus nce
Kev hloov pauv loj coefficient: 30-50% txhim kho
Flame Arresting Principple
Thaum cov nplaim taws hla dhau los ntawm micro channels, cov phab ntsa channel sai nqus cua sov, txo cov nplaim hluav taws kub hauv qab qhov hluav taws xob thiab ua tiav cov nplaim hluav taws.
Maximum Experimental Safe Gap (MESG): Raws li kev faib tawm ntawm pab pawg roj, sintered hlau nplaim ntes qhov khoob yog feem ntau tsim los ntawm 0.5-1.5 hli
Nplaim ntes ceev ceev: Muaj peev xwm nres subsonic rau supersonic nplaim propagation
Kev tawg siab tsis kam: Tiv thaiv qhov cuam tshuam tawg ntau dua lossis sib npaug li 15 bar yam tsis ua haujlwm
Txoj Cai Lij Choj
Cov qauv ua ntej - tsim cov pore tsim tsim kev tswj kev nyem thaum lub sij hawm muaj kev ntxhov siab ntau dhau, tiv thaiv kev puas tsuaj loj.
Pib qhib siab sib txawv: Tsawg dua los yog sib npaug rau ± 5%
Lub sijhawm qhib tag nrho: <50 ms
Vim li cas thiaj xaiv Hlau Sintered Elements?
1. Kev ntseeg ruaj khov tshem tawm qhov chaw ua tsis tiav
Ib txwm welded los yog machined Cheebtsam muaj cov ntsiab lus kev ntxhov siab uas ua rau qaug zog tawg pib nyob rau hauv siab - kub siab - siab cyclic loads. Nyob rau hauv sib piv, hlau sintered lub cev feature ib tug tag nrho hlau rigid monolithic qauv uas tsis muaj interfaces, fundamentally tshem tawm cov ntsiab lus tsis muaj zog.
Tensile zog: Ntau dua los yog sib npaug rau 500 MPa (316L khoom)
Lub neej qaug zog:> 10⁷ cycles nyob rau hauv alternating loads
2. Qhov tseem ceeb ntawm qhov kub thiab txias tsis kam
316L sintered cov ntsiab lus muab sijhawm ntev - haujlwm ruaj khov:
Ua haujlwm kub ntau: -196℃txog 600℃(tshwj xeeb alloys txog 900 degree)
Kev khiav hauj lwm siab: Tsawg dua los yog sib npaug rau 20 MPa (siab dua customizable)
Thermal shock resistance: Ua rau kub ceev hloov ntawm ΔT=300℃yam tsis muaj tawg
3. Cleanable thiab Regenerable rau Extended Life
Thaum cov pore blockage nce siab poob, kev ua tau zoo tuaj yeem rov qab los ntawm rov qab -pulse tu, ultrasonic tu, los yog lwm yam kev tsim dua tshiab.
Kev poob siab pib: <0.02 MPa ntawm tus nqi tsim tawm
Kev poob siab rov qab los tom qab tsim dua tshiab: Ntau dua lossis sib npaug li 95%
Tsim lub neej: 5-10 xyoo (nyob ntawm kev ua haujlwm)
Hom Daim Ntawv Thov Scenarios
1. Petrochemical Kev Lag Luam: Kev faib roj hauv Hydrogenation Reactors
Nyob rau hauv hydrocracking thiab hydrotreating txheej txheem (ib txwm tej yam kev mob: 350-450 degree, 12-18 MPa), hydrogen yuav tsum tau uniformly faib thoob plaws catalyst txaj. Hlau sintered spargers disperse siab-siab hydrogen rau hauv micron- npuas loj, txhim kho roj tau zoo- ua kua sib cuag tau zoo thaum ua kom lub sijhawm ntev - kev cia siab nyob rau hauv huab cua.
2. Kev Lag Luam Tshuaj: Kev Nyab Xeeb Kev Ruaj Ntseg hauv Siab -Cov Khoom Siv Hluav Taws Xob
Nyob rau hauv siab - cov tshuaj tiv thaiv siab rau API synthesis (cov xwm txheej ib txwm: 100–200℃, 2–8 MPa) suav nrog cov kuab tshuaj flammable, hlau sintered nplaim taws ntes cov cuab yeej pab ob txoj haujlwm: overpressure relief paths thiab nplaim taws ntes, muab cov qauv tsim muaj kev nyab xeeb raws li GMP cov cai.
3. Cov Tshuaj Zoo Zoo: Kev Tiv Thaiv Gas Analyzer
Nyob rau hauv online roj tsom xam systems, sintered hlau lim tiv thaiv precision sensors los ntawm cov pa paug paug thaum tiv thaiv corrosive qauv gases (xws li, muaj Cl₂, SO₂) thiab siab - cov qauv ntsuas kub (tsawg dua lossis sib npaug li 500℃).
4. Hydrogen Zog: Hydrogen Storage Material Test
Nyob rau hauv siab - siab hydrogen cia cov kev tshawb fawb systems (ib txwm tej yam kev mob: -196℃rau 80℃, 35–70 MPa), hlau sintered ntsiab ua hauj lwm raws li cov roj distributors thiab plua plav lim, xyuas kom meej cov ntaub ntawv xeem thiab cov cuab yeej muaj kev ruaj ntseg.
