Hauv kev xav tau cov ntaub ntawv lim dej xws li petrochemical catalyst rov qab, siab -kub roj purification, lossis ua cov kua dej siab -viscosity, kev ua tau zoo ntawm cov khoom lim dej ncaj qha rau cov txheej txheem kev ruaj ntseg thiab kev lag luam. Thaum ib txwm siv stainless hlau hmoov sintered lim tau dav siv, lawv cov qauv homogeneous feem ntau cuam tshuam nrog cov kev cov nyom xws li ceev ceev clogging, siab - siab poob, thiab nyuaj tu nyob rau hauv tej yam kev mob. Qhov tshwm sim ntawm Ob -Txheej Asymmetric Sintered Hlau Membrane Lim Element sawv cev rau cov txheej txheem thev naus laus zis tshiab uas tsom rau cov ntsiab lus mob no.
I. Kev Hloov Kho Cov Qauv: Los ntawm "homogeneous Depth Filtration" mus rau "Gradient Surface Filtration"
Qhov tseem ceeb sib txawv ntawm ob pib nrog lawv cov microscopic tsim, uas dictates tag nrho txawv pom mechanisms.
Tsoos Sintered Filter (Symmetric / Homogeneous Structure): Tag nrho cov phab ntsa tuab yog sintered los ntawm cov hmoov hlau ntawm tib yam lossis zoo sib xws particle loj, uas ua rau cov pore faib. Thaum lub sij hawm filtration, cov khoom nkag mus thiab nkag mus tob rau hauv cov tortuous internal channels, tsim ib tug tob pom hom. Qhov no ua rau sab hauv "bridging" blockages uas nyuaj rau tshem tawm tag nrho thaum lub sij hawm rov qab, ua rau tsis zoo siab poob rov qab.
Muab ob npaug rau- Txheej Asymmetric Hlau Membrane Lim: Cov qauv tsim no siv cov qauv tsim tshiab, feem ntau muaj ob txheej sib txawv:
Precision Filtration Layer (Membrane): Ua los ntawm sub-micron lossis micron-sized ultra- cov hmoov hlau zoo, ua kom nyias nyias (piv txwv li, 0.1-0.5mm) tseem ntom ntom txheej nrog cov pore loj. Qhov no yog qhov tseem ceeb ntawm kev ua kom pom tseeb qhov tseeb.
Macro-Porous Support Layer (Substrate): Nyob hauv qab txheej membrane, nws yog sintered los ntawm coarser hlau hmoov los yog fiber ntau hnov, nrog rau qhov pores ho loj dua cov pom txheej (xws li, 5-25μm loj dua). Cov txheej txheem no muab cov cuab yeej ua haujlwm tseem ceeb thiab kev txhawb nqa cov qauv.
Qhov no "thin- txheej precision pom + macro- ntxeem tau muaj zog txhawb" asymmetric tsim hloov cov txheej txheem pom los ntawm "qhov tob" kom ua tau zoo "nto sieving." Particles are primarily retained on the smooth, dense membrane surface, forming an easily removable filter cake, fundamentally solving the problem of deep-seated clogging.
Hauv kev xaus, ob txheej - txheej asymmetric sintered hlau membrane lim sawv cev rau kev hloov kho thev naus laus zis tseem ceeb tshaj li cov qauv tsim homogeneous. Los ntawm kev hloov ntawm qhov sib sib zog nqus, tortuous - txoj kev pom mus rau qhov zoo ntawm qhov chaw sieving, nws muab cov txiaj ntsig zoo tshaj plaws, kev rov qab ua kom zoo dua qub, thiab ua kom muaj kev sib txawv tsawg. Qhov kev tsim kho tshiab no ncaj qha txhais cov txheej txheem txhim kho kom ruaj khov, txo cov nqi kho, thiab lub neej ua haujlwm ntev dua hauv kev xav tau cov ntawv thov xws li kev rov ua kom rov zoo thiab siab -kub roj purification. Rau kev lag luam ua ntej kev ua haujlwm ua haujlwm tau zoo thiab kev ntseeg siab, kev siv lub tshuab lim siab siab no ua rau qhov kev ua tau zoo tshaj plaws.
Nyob rau hauv peb tsab xov xwm tom ntej no, peb yuav delve tob rau hauv qhov kev ua tau zoo leap thiab xaiv cov lus qhia ntawm ob - txheej asymmetric sintered hlau lim.
