Kusiyanitsa pakati pa kusefera kwapamwamba ndi kusefera kwakuya

Zowonekera pazenera zimagwiritsidwa ntchito kusefera kwamtunda komanso zinthu zakumaso zimagwiritsidwa ntchito kusefera kwambiri. Kusiyana kuli motere:

1. Zowonekera (nylon monofilament, chitsulo monofilament) zimalongosola molunjika zosayera pazosefera zomwe zili pamwamba pake. Ubwino ndikuti kapangidwe ka monofilament amatha kutsukidwa mobwerezabwereza ndipo mtengo wogwiritsa ntchito ndi wotsika; Koma choyipa ndi mawonekedwe osefera, omwe ndiosavuta kuyambitsa kutseka kwa thumba la fyuluta. Mtundu uwu wa mankhwala ndioyenera kwambiri kuzosefera kochitikako mwatsatanetsatane, ndipo kusefera kwake ndi 25-1200 μ m.

2. Zida zomverera (nsalu yokhomedwa ndi singano, yankho losokedwa losaluka) ndichinthu chodziwika bwino chazithunzi zitatu, chomwe chimadziwika ndi mawonekedwe osalala komanso porosity yayikulu, yomwe imakulitsa mphamvu zonyansa. Mtundu uwu wa zinthu za CHIKWANGWANI ndi wa njira yolumikizira, kutanthauza kuti, tinthu tating'onoting'ono tating'onoting'ono timayang'aniridwa pamwamba pa ulusi, pomwe ma particles abwino atsekeredwa munthawi yazosefera, chifukwa chake kusefako kuli ndi kusefera kwakukulu Kuchita bwino, Kuphatikiza apo, kutentha kwapamwamba pamatenthedwe, ndiye kuti kugwiritsa ntchito ukadaulo wa sintering pompopompo, kumatha kuletsa kuti fiber isatayike chifukwa champhamvu kwambiri yamadzimadzi pa kusefera; Zinthu zomverera ndizotayika ndipo kulondola kwa kusefera ndi 1-200 μ m.

Zinthu zazikulu za fyuluta zomwe zimamveka ndi izi:

Poliyesitala - fyuluta yomwe imagwiritsidwa ntchito kwambiri, kusakanikirana kwamankhwala, kutentha kwakanthawi kochepera 170-190 ℃

Polypropylene imagwiritsidwa ntchito kusefera kwamadzi m'makampani opanga mankhwala. Ili ndi kukana kwakukulu kwa asidi ndi soda. Kutentha kwake kogwira ntchito ndikosakwana 100-110 ℃

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

Nilong ali ndi mankhwala osokoneza bongo (kupatula asidi), ndipo kutentha kwake kogwira ntchito ndikosakwana 170-190 ℃

Fluoride imagwira ntchito bwino kwambiri pokana kutentha ndi kukana kwamankhwala, ndipo kutentha kogwira ntchito ndikosakwana 250-270 ℃

Kuyerekeza zabwino ndi zovuta pakati pazosefera zakuthupi ndi zosefera zakuya

Pali mitundu yambiri yazosefera pazosefa. Monga mauna oluka, mapepala osungira, pepala lazitsulo, fyuluta yoyeserera komanso kumva, ndi zina zambiri. Komabe, malinga ndi njira zake zosefera, zitha kugawidwa m'magulu awiri, mtundu wapansi ndi mtundu wakuya.

1. Zinthu zakuthambo
Zinthu zakapangidwe kazithunzi zimatchulidwanso ngati fyuluta. Pamwambapa pamakhala ma geometry ena, ma micropores ofanana kapena njira. Amagwiritsidwa ntchito kugwira dothi m'mafuta otsekera. Zoseferazo nthawi zambiri zimakhala zosefera kapena zopindika zopangidwa ndi waya wachitsulo, ulusi wa nsalu kapena zinthu zina. Zosefera zake ndizofanana ndi kugwiritsa ntchito mawonekedwe owonekera. Kuwonongeka kwake kumadalira kukula kwa ma micropores ndi njira.

Ubwino wazomwe zili pamwamba pazosefera: kufotokoza molondola, kugwiritsa ntchito mosiyanasiyana. Yosavuta kuyeretsa, kugwiranso ntchito, moyo wautali wautumiki.

Zoyipa zakapangidwe kazosefera ndi izi: zochepa zowononga; Chifukwa cha kuchepa kwaukadaulo wopanga, kulondola kwake ndikochepera 10um

2. Zosefera zakuya
Zozama zamtundu wazosefera zimatchedwanso zosefera zamtundu wakuya kapena zotengera zamkati zamkati. Zoseferazo zimakhala ndi makulidwe ena, omwe amatha kumvedwa ngati kutayika kwa mitundu yambiri yazosefera. Njira yakunja siyopangidwa mosasintha komanso mulibe kukula kwenikweni kwa kusiyana kwakukulu. Mafutawo akamadutsa mu fyuluta, dothi lomwe lili mumafuta limagwidwa kapena kutsitsidwa kuzama mosiyanasiyana kwa zosefera. Kuti muthe kusewera. Zosefera ndi chofiyira chakuya chomwe chimagwiritsidwa ntchito pama hydraulic system. Kulondola kwake kumakhala pakati pa 3 mpaka 20um.

Ubwino wazinthu zakuya zamtundu wakuya: dothi lalikulu, moyo wautali, wokhoza kuchotsa tinthu tating'onoting'ono tating'onoting'ono tambirimbiri molondola, zosefera mwatsatanetsatane.

Zoyipa zakuthupi zamtundu wakuya: palibe yunifolomu kukula kwa fyuluta zakuthupi. Kukula kwa particles chodetsa sangathe lizilamuliridwa molondola; Ndizosatheka kuyeretsa. Ambiri a iwo ndi disposable. Kugwiritsa ntchito ndi kwakukulu.
