1. Iimathiriyeli ekrwada engundoqo kunye nokuphathwa kwangaphambili kwemathiriyeli yokucoca
1). Izixhobo zeFayibha: Iintsinga ze-Synthetic ezifana ne-polypropylene (PP) kunye ne-polyester (PET) kufuneka zomiswe (umthamo wamanzi Ngaphantsi okanye ulingana ne-0.1%), kunye neentsinga zendalo ezifana nomqhaphu kunye noboya kufuneka zihlanjululwe kwaye zibulawe iintsholongwane.
2). Izinto ze-Granular: I-carbon esebenzayo, isanti ye-quartz, njl. Kufuneka ihlulwe kwaye ihlelwe (i-particle size range 0.5-5mm), kunye nomhlaba we-diatomaceous kufuneka ubalwa kwiqondo lokushisa eliphezulu (i-800 degree) ukwandisa i-porosity.
3). Iisubstrates ezidityanisiweyo: Umzekelo, izinto zokucoca ezigqunyiweyo ze-PTFE kufuneka ziphathwe ngeplasma kwilaphu elisisiseko ukukhulisa ukuncamathelisa (amandla e-peel Makhulu okanye alingana ne-15N/cm).
Ukufuma kokusingqongileyo (RH Ngaphantsi okanye ngokulingana nama-40%) kufuneka kulawulwe ngokungqongqo ngexesha lonyango lwangaphambili ukuthintela ukuguquguquka kwezinto eziphathekayo. Ngokomzekelo, isalathisi se-polypropylene fiber kwi-160-180℃kufuneka izinzile kwi-25-35g / 10min (i-ASTM D1238 standard).
2. Ukuthelekiswa kweenkqubo zokuvelisa eziqhelekileyo kunye neeparitha zobugcisa
1). Inkqubo ye-Meltblown
- Inkqubo: ukunyibilika kwepolymer → phezulu{1}}uxinzelelo lokuhamba komoya olujikelezayo → ukwenza umnatha wefayibha
- Iiparamitha eziphambili: spinneret ububanzi 0.2-0.4mm, ubushushu bomoya oshushu 230-280 degree, ifayibha ububanzi 1-10μm
- Isicelo: imveliso ephezulu{1}}yokusebenza kunye nesezantsi{2}}izixhobo zokuhluza ukuxhathisa (ubuchule bokucoca 99.9% @0.3μm, ukuxhathisa Ngaphantsi okanye ilingana no-50Pa)
2). Inkqubo yokuhlatywa inaliti
- Inkqubo: ukubekwa kwefiber → kaninzi-ukuhlatywa kwepleyiti yenaliti (inaliti rhoqo 800-1200 amaxesha/min) → ukomelezwa kwimvakalelo
- Izinto eziluncedo: inokuvelisa izinto ezintathu zokucoca ubume besakhiwo, ubunzima begram 100-800g/m², ukungena komoya 5-20cm³/cm²/s
3). Inkqubo yeSintering
- Izinto zokucoca isinyithi/i-ceramic kufuneka zicinezelwe zibe ngumgubo (uxinzelelo lwe-20-50MPa) kwaye emva koko zifakwe kwiqondo lokushisa eliphezulu (i-1100-1300℃yensimbi engenasici kunye ne-1600℃ye-alumina)
- I-Porosity inokulawulwa kwi-30-60%, kwaye ukumelana nobushushu kungaphezulu kwe-500 degree
3. Thumela{1}}iteknoloji yokusebenza kunye nokuphucula ukusebenza
1). Ukulungiswa komphezulu:
- Unyango lwe-Hydrophobic (efana ne-engile yokudibanisa i-fluorocarbon Enkulu kuno okanye ilingana ne-120℃)
- Ukugqitywa kwe-Antibacterial (i-ion yesilivere ilayisha 0.5-2%)
2). Ukomelezwa kolwakhiwo:
- I-Ultrasonic welding (i-frequency 20kHz) ukuphucula amandla omthungo
- Unyango olushushu lwe-calendering ukwenza ubungakanani bokuhanjiswa kwepore kufane kakhulu (ixabiso leCV Ngaphantsi okanye lilingana ne-15%)
