1. Zopangira zoyambira komanso kusanja kwa zinthu zosefera
1). Zipangizo za Fiber: Ulusi wopangidwa monga polypropylene (PP) ndi poliyesitala (PET) uyenera kuumitsidwa (madzi Ochepera kapena ofanana ndi 0.1%), ndipo ulusi wachilengedwe monga thonje ndi ubweya uyenera kuchotsedwa ndi kupha tizilombo toyambitsa matenda.
2). Zipangizo za granular: Mpweya wa carbon, mchenga wa quartz, ndi zina zotero ziyenera kusefa ndi kusinthidwa (tinthu tating'ono tosiyanasiyana 0.5-5mm), ndipo dziko lapansi la diatomaceous liyenera kuwerengedwa pa kutentha kwakukulu (madigiri 800) kuti awonjezere porosity.
3). Zophatikiza zigawo: Mwachitsanzo, PTFE TACHIMATA fyuluta zipangizo ayenera madzi a m'magazi kuchitiridwa pa nsalu m'munsi kuti kumamatira (peel mphamvu Kuposa kapena ofanana 15N/cm).
Chinyezi chachilengedwe (RH Ochepera kapena wofanana ndi 40%) uyenera kuyendetsedwa mosamalitsa panthawi yokonzekera kuti tipewe kusinthasintha kwazinthu zakuthupi. Mwachitsanzo, ndondomeko yosungunuka ya polypropylene fiber pa 160-180 digiri iyenera kukhala yokhazikika pa 25-35g / 10min (ASTM D1238 standard).
2. Kuyerekeza kwa njira zopangira zopangira komanso magawo aukadaulo
1). Meltblown process
- Njira: kusungunuka kwa polima → kukwezeka-kuzungulira kwa mpweya woponderezedwa → kupanga fibre mesh
- Zofunikira zazikulu: spinneret diameter 0.2-0.4mm, kutentha kwa mpweya wotentha 230-280℃, fiber diameter 1-10μm
- Kugwiritsa ntchito: Kupanga kwapamwamba-zochita zowoneka bwino komanso zotsika-zosefera zosefera bwino 99.9% @0.3μm, kukana Kuchepera kapena kufanana ndi 50Pa)
2). Njira yokhomerera singano
- Njira: kuyala CHIKWANGWANI → kangapo-kuboola kwa singano (mafupipafupi a singano 800-1200/mphindi) → kulimbikitsa kuti mumve
- Ubwino: imatha kupanga zosefera zitatu-zowoneka bwino, kulemera kwa gramu 100-800g/m², mpweya permeability 5-20cm³/cm²/s
3). Sintering ndondomeko
- Zida zosefera zachitsulo/ceramic ziyenera kukanikizidwa kukhala ufa (pressure 20-50MPa) kenako n’kutenthedwa ndi kutentha kwambiri (madigiri 1100-1300 pazitsulo zosapanga dzimbiri ndi 1600 digiri ya alumina)
- Porosity imatha kuwongoleredwa pa 30-60%, ndipo kutentha kumapitilira madigiri 500
3. Tumizani-ukadaulo wokonza ndi kukhathamiritsa kwa magwiridwe antchito
1). Kusintha pamwamba:
- Chithandizo cha Hydrophobic (monga ngodya ya fluorocarbon coating coating Greater kuposa kapena yofanana ndi 120 degrees )
- Antibacterial finishing (silver ion loading 0.5-2%)
2). Kulimbitsa:
- Ultrasonic welding (mafupipafupi 20kHz) kuti muwongolere msoko
- Chithandizo chotentha cha kalendala kuti kugawa kukula kwa pore kukhale kofanana (mtengo wa CV Wochepera kapena wofanana ndi 15%)
