Kusiyana pakati pa kusefera kwapamtunda ndi kusefera kwakuya

Zinthu zowonekera zimagwiritsidwa ntchito posefera pamwamba komanso zomverera zimagwiritsidwa ntchito kusefa kwambiri.Kusiyana kwake kuli motere:

1. Chophimba chotchinga (nylon monofilament, chitsulo monofilament) chimasokoneza mwachindunji zonyansa mu kusefera pamwamba pa zinthuzo.Ubwino wake ndikuti mawonekedwe a monofilament amatha kutsukidwa mobwerezabwereza ndipo mtengo wogwiritsa ntchito ndi wotsika;Koma choyipa chake ndi kusefera kwapamtunda, komwe kumakhala kosavuta kupangitsa kutsekeka kwa thumba la fyuluta.Zogulitsa zamtunduwu ndizoyenera kwambiri pazosefera zowoneka bwino komanso zocheperako, ndipo kusefera kolondola ndi 25-1200 μ m.

2. Zomverera (nsalu yokhomeredwa ndi singano, nsalu yowombedwa yopanda nsalu) ndi chinthu chodziwika bwino chamitundu itatu, chomwe chimadziwika ndi mawonekedwe otayirira a fiber ndi porosity yayikulu, yomwe imawonjezera mphamvu ya zonyansa.Mtundu uwu wa zinthu zamtundu wa fiber ndi wa pawiri interception mode, ndiye kuti, tinthu tating'onoting'ono tambiri tambiri timayikidwa pamwamba pa ulusi, pomwe tinthu tating'onoting'ono timatsekeredwa mumtambo wakuya wa zinthu zosefera, kotero kusefera kumakhala ndi kusefera kwapamwamba. Kuchita bwino, Kuonjezera apo, kutentha kwapamwamba kwa kutentha kwapamwamba, ndiko kuti, kugwiritsa ntchito teknoloji ya sintering pompopompo, kungalepheretse bwino kuti fiber isawonongeke chifukwa cha kuthamanga kwamadzimadzi panthawi ya kusefera;Zomwe zimamveka zimatha kutaya ndipo kusefa kulondola ndi 1-200 μ m.

Zida zazikulu za fyuluta zomveka ndi izi:

Polyester - fiber fiber yomwe imagwiritsidwa ntchito kwambiri, kukana kwamankhwala abwino, kutentha kogwira ntchito zosakwana 170-190 ℃

Polypropylene imagwiritsidwa ntchito kusefera zamadzimadzi m'makampani opanga mankhwala.Ali ndi acid komanso kukana kwa alkali.Kutentha kwake kogwira ntchito kumakhala kosakwana 100-110 ℃

Ubweya - ntchito yabwino yotsutsa zosungunulira, koma si yoyenera anti acid, kusefera kwa alkali

Nilong ali ndi kukana kwamankhwala abwino (kupatula kukana kwa asidi), ndipo kutentha kwake kumakhala kosakwana 170-190 ℃.

Fluoride ali ndi ntchito yabwino ya kukana kutentha ndi kukana mankhwala, ndi kutentha ntchito ndi zosakwana 250-270 ℃

Kuyerekeza ubwino ndi kuipa pakati pa zinthu zosefera pamwamba ndi zakuya zosefera

Pali mitundu yambiri yazosefera zosefera.Monga nsalu waya mauna, fyuluta pepala, zitsulo pepala, sintered fyuluta chinthu ndi anamva, etc. Komabe, malinga ndi njira zake zosefera, zikhoza kugawidwa m'mitundu iwiri, kutanthauza pamwamba mtundu ndi mtundu kuya.

1. Zosefera pamwamba
Zosefera zamtundu wa pamwamba zimatchedwanso absolute filter material.Pamwamba pake pali geometry, yunifolomu micropores kapena njira.Amagwiritsidwa ntchito kuti agwire dothi mumafuta otsekereza.Zosefera nthawi zambiri zimakhala zomveka kapena zosefera zopangidwa ndi waya wachitsulo, ulusi wansalu kapena zida zina.Mfundo yake yosefera ndi yofanana ndi kugwiritsa ntchito chophimba cholondola.Kulondola kwake kusefa kumadalira miyeso ya geometric ya ma micropores ndi njira.

Ubwino wa zinthu zosefera zamtundu wa pamwamba: kufotokozera molondola zatsatanetsatane, ntchito zambiri.Zosavuta kuyeretsa, zogwiritsidwanso ntchito, moyo wautali wautumiki.

Zoyipa za zinthu zamtundu wamtundu wamtundu wamtundu wamtunduwu ndi izi: zonyansa zazing'ono;Chifukwa cha kuchepa kwa ukadaulo wopanga, kulondola kwake ndikosakwana 10um

2. Zosefera zakuya
Zosefera zamtundu wakuya zimatchedwanso zosefera zamtundu wakuya kapena zamkati zamtundu wamtundu wamkati.Zosefera zili ndi makulidwe ena, omwe amatha kumveka ngati mawonekedwe apamwamba a zosefera zamtundu wambiri.Njira yamkati imakhala yosakhazikika komanso yopanda kukula kwake kwa kusiyana kwakukulu.Mafuta akamadutsa muzosefera, dothi lamafuta limagwidwa kapena kutsatiridwa mozama mosiyanasiyana.Kuti agwire ntchito ya kusefera.Pepala losefera ndizinthu zosefera zakuya zomwe zimagwiritsidwa ntchito mu hydraulic system.Kulondola nthawi zambiri kumakhala pakati pa 3 ndi 20um.

Ubwino wazinthu zosefera zamtundu wakuya: dothi lalikulu, moyo wautali wautumiki, wokhoza kuchotsa tinthu tating'onoting'ono kwambiri kuposa kulondola ndi mzere, kusefa kwakukulu.

Kuipa kwa zinthu zakuya zamtundu wa fyuluta: palibe kukula kofanana kwa kusiyana kwa zinthu zosefera.Kukula kwa particles zonyansa sangathe kulamulidwa molondola;Ndi pafupifupi zosatheka kuyeretsa.Ambiri aiwo ndi otayidwa.Kudya ndi kwakukulu.
