1. Cov ntaub ntawv raw thiab pretreatment ntawm cov khoom lim
1). Cov ntaub ntawv fiber ntau: cov lus hluavtaws xws li polypropylene (PP) thiab cov tsiaj txhu muaj ntau dua li cov paj rwb thiab ntaub so ntswg thiab cov tshuaj tua kab mob.
2). Cov khoom siv granular: actartz xuab zeb, thiab lwm yam. Lub ntiaj teb loj dua 0.5-5 xyoos
3). Composite substrates: Piv txwv, PTFE coated lim cov ntaub ntawv yuav tsum tau yuav kho cov ntaub los txhim kho adhance (tev lub zog ntau dua los yog sib npaug rau 15n / cm).
Cov av noo ib puag ncig (RAWS tsawg dua lossis sib npaug ntawm 40%) yuav tsum tau nruj me ntsis tswj tau thaum lub sijhawm pretreatment theem kom tsis txhob hloov pauv hauv cov khoom siv cov khoom siv. Piv txwv li, lub melt index ntawm polypropylene fiber ntau ntawm 160-180℃yuav tsum tau ruaj khov ntawm 25-35G / 10min (Astm D1238 Txuj Ci).
2. Kev sib piv ntawm cov txheej txheem conttrStream ntau lawm thiab cov kev tsis txheeb
1). Meltblown txheej txheem
{-}}} polymer Melting → high - siab → fiber ntau mi fiber ntau tuav
{{0- Qhov tseem ceeb Incameters: Spinneret Inch 0.2 -0.4mm, cua kub kub 230-280 degree, fiber dwv 1-10μm
{-} Daim ntawv thov: Kev Tsim Kho Cov Khoom Siv High-}}} {} {} {μm, tsis tshua muaj siab dua lossis sib npaug nrog 50pa)
2). Koob punching txheej txheem
{- txheej txheem: fiber ntau - Rab Koob Phaj Phaj Phaj Phaj Puv (Koob zaus 8 min) → kev txhawb zog rau hauv kev xav
- Cov txiaj ntsig: tuaj yeem tsim peb {{1} tus qauv tsav tsheb siv 100-800g / m², huab cua permeability 5-20cm³ / s
3). Sintering txheej txheem
{{0- cov ntaub ntawv lim hlau / cov cav ntoo
{{0 {0} Porosity tuaj yeem tswj tau ntawm 30-60%, thiab qhov kub tsis kam yog siab dua 500 degree
3. Post {- Ua Tshuab thiab Kev Ua Haujlwm Zoo
1). Kho qauv:
-} hydrophobic kev kho (xws li fluorocarbon Txheej fluorocarbon Txheej kev sib cuag Angle ntau dua lossis sib npaug rau 120 degree)
{{0 -} cov tshuaj tua kab mob (cov nyiaj ion loading 0.5-2%)
2). Cov qauv kev teeb tsa:
{{0- Ulte Ultrasonic Vuam (Zaus 20kHz) txhawm rau txhim kho cov leeg muaj zog
- kub} kub kub kho kom zoo dua kev kho kom ua rau lub luag hauj lwm loj dua (CV tus nqi tsawg dua lossis sib npaug rau 15%)
