Nyob zoo cov neeg nyiam daim tawv nqaij! Hnub no, peb yuav tham txog qhov loj ntawm lub qhov hws, thiab vim li cas nws thiaj li tseem ceeb heev uas yuav tsum nkag siab. Tej zaum koj yuav tau hnov txog lub qhov hws ua ntej, tab sis koj puas paub tiag tiag vim li cas lub qhov hws thiaj li tseem ceeb? Nyeem ntxiv kom paub!
Cov qhov hws yog dab tsi?
Hauv cov ntsiab lus ntawm cov khoom lim, cov qhov me me yog cov qhov me me lossis cov channel hauv cov khoom siv lim uas tso cai rau kev hla ntawm cov kua lossis cov pa roj thaum ntes cov khoom khov lossis cov khoom ua qias tuaj.
Cov khoom lim dej yog tsim los tshem tawm cov khoom tsis huv thiab cov pa phem ntawm cov kua lossis cov pa roj, thiab qhov ua tau zoo ntawm lub lim dej yog txiav txim siab feem ntau los ntawm qhov loj me thiab kev faib tawm ntawm cov qhov hauv cov khoom siv lim dej.
Qhov loj ntawm cov qhov me me feem ntau ntsuas hauv microns, nrog rau qhov me me dua qhia txog lub peev xwm ntau dua los lim cov khoom me me. Txawm li cas los xij, lub lim dej uas muaj qhov me me heev kuj tseem yuav muaj qhov nrawm qis dua, uas tuaj yeem cuam tshuam rau nws qhov kev ua haujlwm zoo.
Cov khoom siv lim dej sib txawv siv tau ntau yam khoom siv thiab cov qauv qhov hws kom ua tiav cov hom phiaj lim dej tshwj xeeb, xws li tshem tawm cov khoom me me ntawm qee qhov loj me lossis cais cov kua sib txawv. Cov khoom siv lim dej feem ntau suav nrog cellulose, polypropylene, thiab ntau hom membranes lossis mesh.
Qhov loj ntawm qhov pore yog dab tsi?
Tam sim no peb paub tias cov qhov hws yog dab tsi, cia peb tham txog lawv qhov loj. Qhov loj ntawm qhov hws yog hais txog txoj kab uas hla ntawm qhov qhib hauv daim tawv nqaij. Cov qhov hws tuaj yeem muaj qhov loj me txij li tsawg dua 0.2 micrometers mus txog ntau dua 0.5 millimeters. Qhov ntawd yog ntau yam! Qhov loj ntawm qhov hws tuaj yeem ntsuas tau siv lub cuab yeej tshwj xeeb hu ua poreometer, uas siv lub koob yees duab thiab software los tshuaj xyuas qhov chaw ntawm daim tawv nqaij.
Vim li cas qhov loj ntawm qhov pore thiaj li tseem ceeb rau kev lim dej hauv kev lag luam?
Qhov loj ntawm cov qhov (pores) yog ib qho tseem ceeb uas yuav tsum xav txog rau cov tshuab lim dej hauv kev lag luam vim nws txiav txim siab seb hom khoom me me thiab cov pa phem twg tuaj yeem tshem tawm tau zoo ntawm cov kua lossis cov pa roj. Qhov loj ntawm cov qhov hauv lub lim dej txiav txim siab qhov loj tshaj plaws ntawm cov khoom me me uas tuaj yeem hla dhau nws.
Yog tias qhov loj ntawm lub qhov loj dhau, cov khoom me me thiab cov pa phem yuav hla dhau lub lim thiab tseem nyob hauv cov khoom kawg. Ntawm qhov tod tes, yog tias qhov loj ntawm lub qhov me dhau, lub lim yuav raug txhaws lossis qias sai dhau, ua rau nws txoj haujlwm tsis zoo thiab yuav tsum tau saib xyuas lossis hloov ntau zaus.
Yog li ntawd, kev xaiv qhov loj ntawm qhov pore kom haum rau lub tshuab lim dej yog qhov tseem ceeb heev rau kev ua kom ntseeg tau tias qib kev huv thiab kev huv si tau ua tiav hauv cov khoom kawg. Qhov loj ntawm qhov pore yuav tsum tau xaiv raws li daim ntawv thov tshwj xeeb, xav txog qhov loj me thiab hom khoom me me uas yuav tsum tau tshem tawm, qhov nrawm ntawm cov kua lossis roj, thiab lwm yam tseem ceeb.
Yog li ntawd, rau ntau yam kev lag luam, lub kaw lus lim tshwj xeeb, feem ntau yog xav tau cov khoom nrog qhov loj me sib txawv, tom qab ntawd pab peb lim qee qhov tsis huv los ntawm peb cov ntaub ntawv.
Yuav ua li cas OEM qhov loj me rau cov lim dej porous?
OEM (Tus Tsim Khoom Siv Thawj) qhov loj me rau cov lim dej uas muaj qhov porous feem ntau yuav tsum tau kho qhov loj me ntawm lub lim kom tau raws li qhov xav tau tshwj xeeb ntawm ib daim ntawv thov lossis kev lag luam tshwj xeeb.
