Lim ntawvyog ib lo lus dav dav rau cov khoom siv lim xov xwm tshwj xeeb. Yog hais tias nws yog ntxiv subdivided, nws muaj: roj lim ntawv, npias lim ntawv, siab kub lim ntawv, thiab hais txog. Tsis txhob xav tias ib daim ntawv me me zoo li tsis muaj txiaj ntsig. Qhov tseeb, cov txiaj ntsig uas cov ntawv lim tuaj yeem tsim tau qee zaum irreplaceable los ntawm lwm yam.
Los ntawm cov qauv ntawm daim ntawv, nws yog ua los ntawm interwoven fibers. Cov fibers yog staggered nrog ib leeg los tsim ntau lub qhov me me, yog li cov permeability rau roj los yog kua yog zoo. Ntxiv mus, lub thickness ntawm daim ntawv yuav loj los yog me me, cov duab yog yooj yim rau txheej txheem, thiab folding thiab txiav yog yooj yim heev. Nyob rau tib lub sijhawm, nyob rau hauv cov nqe lus ntawm cov nqi tsim khoom, kev thauj mus los thiab kev cia khoom, tus nqi qis dua.
Tsuas tso tseg,kas fes lim ntawvtuaj yeem siv rau kev sib cais, purification, concentration, decolorization, rov qab, thiab lwm yam. Qhov no tseem ceeb heev rau kev tiv thaiv ib puag ncig, kev noj qab haus huv ntawm tib neeg, khoom siv tu, kev txuag nyiaj thiab lwm yam.
Qee cov ntaub ntawv raw siv hauv cov ntawv lim yog tag nrho cov nroj tsuag fibers, xws li tshuaj ntsuam xyuas cov ntawv lim ntawv; qee qhov yog iav fibers, hluavtaws fibers, aluminium silicate fibers; qee qhov siv cov fibers cog thiab ntxiv qee cov fibers, txawm tias muaj cov hlau fibers. Ntxiv nrog rau cov khoom sib xyaw saum toj no, qee cov khoom ntim, xws li perlite, activated carbon, diatomaceous earth, ntub lub zog tus neeg sawv cev, ion pauv resin, thiab lwm yam, yuav tsum tau ntxiv raws li cov qauv. Tom qab cov txheej txheem ua tiav, cov ntawv tiav uas tau kos los ntawm lub tshuab ntawv yog ua tiav raws li qhov yuav tsum tau ua: nws tuaj yeem txau, impregnated, lossis lined nrog lwm cov ntaub ntawv.
Tsis tas li ntawd, nyob rau hauv qee qhov tshwj xeeb, cov ntawv lim tseem yuav tsum muaj qhov kub thiab txias, tiv thaiv hluav taws thiab dej tsis kam, nrog rau adsorption thiab mildew kuj. Piv txwv li, kev pom ntawm cov pa roj av hauv av thiab kev pom cov roj zaub ua kom zoo, thiab lwm yam.
