Yuav ua li cas khaws Melt Blown Non-Woven Fabric kom paub tseeb tias kev ua haujlwm zoo?

Melt blown non-woven npuag yog cov khoom siv lim dej ntawm lub qhov ncauj qhov ntswg, uas yog txiav txim siab los ntawm cov txheej txheem lim dej ntawm cov khoom siv lim dej, feem ntau muab faib ua cov khoom thaiv thiab electrostatic adsorption. Yog li cov lus nug yog, peb yuav ua li cas kom ntseeg tau tias qhov pom kev ua haujlwm ntawm cov khoom siv yaj uas tsis yog-woven npuag tsis deteriorate thaum khaws cia?

1, Mechanical teeb meem tuaj yeem tshwm sim hauv cov xwm txheej hauv qab no

1. Cov dej me me uas muaj qhov loj dua 5um hauv huab cua tuaj yeem thaiv cov khoom siv lim.

2. Thaum txoj kab uas hla ntawm cov hmoov av nplua nuj tsawg dua 3um, cov hmoov av zoo yog mechanically intercepted los ntawm nkhaus pore fiber txheej nyob rau hauv lub npog ntsej muag lim khoom.

3. Thaum cov particle loj thiab airflow tshaj tawm yog ob qho tib si loj, cov khoom raug ntes vim inertia thiab fiber ntau sib tsoo. Thaum cov particle flow velocity tsawg, cov khoom raug ntes vim Brownian motion thiab cuam tshuam rau cov fiber ntau.

2, Electrostatic adsorption

Feem ntau, nyob rau hauv cov txheej txheem ntawm qhuav tshuab ziab khaub ncaws, kev kho polar yog siv los ntxiv cov hluav taws xob zoo li qub rau cov ntaub tsis-woven, uas muaj cov nyhuv electrostatic adsorption. Electrostatic adsorption yog hais txog kev ntes cov kab mob hauv plua plav thiab kab mob los ntawm Coulomb quab yuam ntawm cov fibers them thaum cov fibers ntawm cov khoom lim raug them.

Muaj ob txoj hauv kev los txhim kho tus nqi khaws cia ntawm cov khoom siv hluav taws xob:

1. Los ntawm kev ua kom cov crystallinity thiab mechanical deformation ntawm cov khoom, cov qauv ntawm cov khoom hloov, tsim slender pore raws los npaj nqi drift.

2. Los ntawm kev qhia cov khoom siv ntxiv nrog cov khoom ntim khoom, cov cuab yeej them nqi raug tsim los ntes cov nqi.

3, Yuav ua li cas khaws daim npog ntsej muag meltblown ntaub

Tus yuam sij rau kev txhim kho qhov pom kev ua haujlwm ntawm lub qhov ncauj qhov ntswg yog nyob rau hauv electrostatic cia ntawm meltblown non-woven fabrics. Melt blown non-woven npuag polarizers yog rhiab heev rau cov av noo ib puag ncig. Thaum lub sij hawm kev thauj mus los thiab khaws cia ntawm cov ntaub yaj yaj, nws yog ib qho tsim nyog kom tsis txhob muaj cov av noo nyob ib puag ncig.
