Lub hauv paus ntsiab lus ntawmcosmetic oil-absorbing ntawvFeem ntau yog raws li ob lub cev tshwm sim: adsorption thiab infiltration. cov
Ua ntej, lub hauv paus ntsiab lus ntawm adsorption yog tias qhov saum npoo ntawm cov roj-absorbing ntawv muaj ib qho lipophilicity, uas tso cai rau cov roj yuav adsorbed ntawm daim ntawv. Adsorption yog ib qho tshwm sim ntawm lub cev tshwm sim los ntawm cov khoom uas dhau los ntawm qhov chaw ntawm qhov adsorbent. Qhov saum npoo ntawm cov adsorbent muaj thaj chaw loj tshwj xeeb thiab muaj qee yam tshuaj lom neeg, thiab tuaj yeem nqus cov khoom nyob ib puag ncig. Cov fibers ntawm daim ntawv roj-absorbing yog hollow zoo li xyoob, thiab cov duab thiab qhov chaw ntawm lub lumen txawv. Qhov loj ntawm thaj chaw saum npoo, qhov muaj peev xwm ua kom cov roj adsorb ntau dua. Cov fibers no muaj hydrophobic thiab lipophilic zog, uas ua rau cov roj-absorbing ntawv kom zoo nqus cov roj ntawm lub ntsej muag. cov
Qhov thib ob, txoj cai infiltration yog tias tusoil-absorbing ntawvfeem ntau yog siv cov txheej txheem hauv qab saum npoo los ua kom nws qhov sib txawv ntawm cov fiber ntau tsim nyog, tsim cov capillary nkaus, kom daim ntawv muaj cov yam ntxwv infiltration. Lub capillary kev txiav txim ntawm daim ntawv tso cai rau cov roj kom sib npaug ntawm cov fiber ntau ntawm daim ntawv, thiab diffuse sab hauv los ntawm kev ua haujlwm capillary ntawm cov ntawv nyob ib puag ncig. cov
Hauv cov ntsiab lus, cov ntawv pleev xim roj-absorbing zoo tshem tawm cov roj ntau dhau ntawm lub ntsej muag los ntawm kev siv lub cev tshwm sim ntawm adsorption thiab infiltration, ua kom daim tawv nqaij tshiab thiab huv.
