Porous hlau lim yog cov khoom siv ua haujlwm tsim los ntawm cov hmoov hlau, woven meshes, los yog fibers los ntawm precision sintering txheej txheem, tsim peb - qhov sib txuas ntawm qhov pore cov qauv uas sib txuas cov khoom siv ntawm cov hlau nrog cov yam ntxwv pom ntawm cov khoom ntxeem tau. Lawv cov ntawv thov kev lag luam txuas mus deb dhau ntawm cov khoom yooj yim- cov kua dej sib cais, ua haujlwm ua haujlwm tseem ceeb hauv ntau qhov chaw.
I. Precision Filtration thiab Separation Technology
Lub ntsiab functionality ntawm ntxeem tau hlau lim nyob rau hauv lawv precisely controllable pore loj tis, ua kom pom ntawm cov qhab nia sib txawv:
Ultra-Neeg Gas Lim: Nickel-raws li los yog 316L stainless hlau ntxeem tau cov ntxaij lim dej hauv semiconductor raug ua tiav ULPA (Ultra Low Penetration Air) kev faib tawm, kom ntseeg tau cov ntsiab lus hauv qab 0.1ug / m³ hauv qhov chaw huv si.
High-Tub kub Gas Dedusting: Lim ua los ntawm Hastelloy lossis Inconel series cov ntaub ntawv ua haujlwm tsis tu ncua ntawm 800 degree, xa mus rau hauv siab -kub flue gas kho tshuab rau thee- hluav taws xob fais fab nroj tsuag.
Kev sib cais ntawm emulsion: Los ntawm kev hloov pauv lub zog saum npoo, titanium-raws li cov kua nplaum ua tau zoo demulsification ntawm cov roj- dej emulsions nrog kev sib cais efficiency ntau tshaj 99.9%.
II. Fluid Dynamics Control Systems
Cov qauv pore tshwj xeeb ntawm cov hlau ntxeem tau ua rau lawv zoo tagnrho cov dej tswj cov ntsiab lus:
Cov Cuab Yeej Tsis Txaus Siab: Ntau- txheej sintered hlau lim hauv siab - cov pa roj carbon monoxide kis tau tus mob tswj lub siab hloov pauv hauv ± 0.5bar thaum tib lub sijhawm lim cov khoom sib xyaw.
Precision Flow Regulation: Gradient pore design enables linear flow control in Reynolds number ranges of 5-5000, siv nyob rau hauv cov txheej txheem tshuaj metering systems.
Acoustic Attenuation: Porous hlau silencers nyob rau hauv lub dav hlau cav roj systems txo cov suab nrov los ntawm 20-35dB thaum tswj roj pom functionality.
III. Txheej txheem Intensification thiab Reaction Engineering
Raws li cov khoom siv ua haujlwm tau zoo, cov hlau ntxeem tau ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kev lag luam:
Catalytic Reactors: Catalyst-loaded porous hlau substrates ua qauv qhia 3-5 npaug ntau dua qhov kev hloov pauv ntau dua li cov khoom ntim-txheej reactors nrog 60% txo qhov kev poob siab.
Gas Distribution Systems: Titanium porous gas spargers nyob rau hauv bioreactors ua tiav oxygen mass transfer coefficients (kLa) tshaj 200h⁻¹.
Electrochemical Reactors: Raws li cov txheej txheem thauj khoom ntxeem tau (PTL) hauv PEM electrolyzers, sintered titanium cov ntaub ntawv muab cov khoom siv hluav taws xob zoo heev thiab muaj peev xwm tswj tau roj.
IV. Kev Tiv Thaiv Kev Nyab Xeeb
Cov nplaim taws ntes thiab tawg- cov yam ntxwv pov thawj tshwm sim los ntawm lawv qhov tshwj xeeb ntawm thaj chaw siab thiab thermal conductivity:
Flame Arrestors: Stainless hlau ntxeem tau nplaim taws ua raws li EN ISO 16852 ntawv pov thawj, tiv thaiv deflagration nplaim propagation tshaj 300m / s.
Breather Valve Kev Tiv Thaiv: Cov ntxaij lim dej ntxeem tau ntsia ua ntej cov tshuaj cia tank breather li qub ua kom muaj pa rov qab thiab tiv thaiv tawg.
Nuclear-Qib Lim: Nickel-alloy porous filters rau nuclear fais fab nroj tsuag qhov cua tshuab ua tau raws li ASME N509 qauv.
V. Thermal Management and Energy Systems
Cov qauv tshwj xeeb ntawm cov hlau ntxeem tau pom muaj peev xwm tseem ceeb hauv kev siv hluav taws xob:
Theem Hloov Thaum tshav kub kub Exchangers: Copper ntxeem tau wicks nyob rau hauv cov kav dej kub tsim capillary rog tshaj 20kPa, nrog tshav kub hloov ceev ceev 5-8 npaug tshaj li cov pa radiators.
Roj Cells: Raws li cov roj diffusion txheej hauv PEMFCs, carbon fiber-cov hlau ntxeem tau ntxiv muab cov hluav taws xob tshwj xeeb thiab kev tswj dej muaj peev xwm.
Ua Kua Hlau Txias: Cov ntaub ntawv tungsten ntxeem tau zoo tswj kev ntws thiab hloov kub ntawm cov kua lithium- txhuas alloys hauv fusion reactor pam tshuab.
