Ma spunbond ndi meltblown ndi matekinoloje opangira nsalu zosalukidwa pogwiritsa ntchito ma polima ngati zida zopangira, ndipo kusiyana kwawo kwakukulu kuli m'boma ndi njira zopangira ma polima.
Mfundo ya spunbond ndi meltblown
Spunbond imatanthawuza nsalu yopanda nsalu yopangidwa ndi kutulutsa zinthu za polima mumkhalidwe wosungunuka, kupopera zinthu zosungunuka pa rotor kapena nozzle, kutambasula ndi kulimba mofulumira mumkhalidwe wosungunuka kuti apange zipangizo za fibrous, ndiyeno kuluka ndi kulumikiza ulusi kudzera mu malamba a mesh kapena electrostatic spinning. Mfundo yake ndi kutulutsa polima wosungunuka kudzera mu extruder, ndiyeno kudutsa njira zingapo monga kuziziritsa, kutambasula, ndi kutambasula molunjika kuti potsirizira pake apange nsalu yopanda nsalu.
Meltblown ndi njira yopopera mankhwala a polima kuchokera pamalo osungunuka kudzera m'milomo yothamanga kwambiri. Chifukwa cha kukhudzidwa ndi kuziziritsa kwa mpweya wothamanga kwambiri, zida za polima zimakhazikika mwachangu kukhala filaments ndikubalalika mumlengalenga. Kenako, potera mwachilengedwe kapena kukonza konyowa, nsalu yabwino kwambiri yosalukidwa imapangidwa. Mfundo yake ndi kupopera zinthu za polima zotentha kwambiri, kuzitambasulira kukhala ulusi wabwino kwambiri kudzera mu mpweya wothamanga kwambiri, ndikuzilimbitsa mwachangu kukhala zinthu zokhwima mumlengalenga, kupanga wosanjikiza wa nsalu zabwino zosalukidwa.
Kusiyanitsa pakati pa nsalu yosungunula yowombedwa yopanda nsalu ndi spunbond yopanda nsalu
Njira zosiyanasiyana zopangira
Nsalu yosungunula yosalukidwa imapangidwa kudzera muukadaulo wopopera mbewu mankhwalawa, pomwe zida za polima zimasungunuka ndikupopera pa template, pomwe nsalu yopanda nsalu ya spunbond imasinthidwa kukhala nsalu yosalukidwa ndikusungunula ulusi wamankhwala kukhala ulusi wolimba pogwiritsa ntchito zosungunulira kapena kutentha kwambiri, kenako ndikusinthidwa kukhala nsalu yosalukidwa kudzera pamakina kapena kusintha kwamankhwala.
Njira zamakono zamakono
(1) Zofunikira pazakudya ndizosiyana. Spunbond imafuna MFI ya 20-40g / min ya PP, pamene kusungunuka kumafuna 400-1200g / min.
(2) Kutentha kozungulira kumasiyana. Kuzungulira kwa spunbond ndi 50-80 ℃ kuposa kupota kwa spunbond.
(3) Liŵiro lotambasula la ulusi limasiyanasiyana. Spunbond 6000m/mphindi, kusungunula kuwombedwa 30km/mphindi.
(4) Mwamwayi, mtundawu si wosalala. Spunbond 2-4m, Sungunulani kuwombedwa 10-30cm.
(5) Kuzizira ndi kutambasula zinthu ndizosiyana. Ulusi wa Spunbond umakokedwa pogwiritsa ntchito mpweya wozizira wa 16 ℃ wokhala ndi mphamvu yabwino/yoipa, pomwe ma fuse amawomberedwa pogwiritsa ntchito mpando wotentha wokhala ndi kutentha pafupifupi 200 ℃.
Kusiyana kwa thupi
Nsalu za Spunbondkukhala ndi mphamvu zosweka kwambiri komanso kutalika kuposa nsalu zosungunuka, zomwe zimapangitsa kuti mtengo wake ukhale wotsika. Koma kumverera kwa dzanja ndi maukonde a fiber mesh ndizovuta.
Nsalu ya Meltblown ndi yofewa komanso yofewa, yokhala ndi kusefera kwakukulu, kukana kutsika, komanso magwiridwe antchito abwino. Koma otsika mphamvu ndi osauka kuvala kukana.
Kufananiza makhalidwe ndondomeko
Chimodzi mwamakhalidwe a nsalu zosungunula zowombedwa ndizomwe zimakhala zocheperako, nthawi zambiri zosakwana 10um (micrometer), ulusi wambiri wokhala ndi fineness pakati pa 1-4um. Mphamvu zosiyanasiyana pa mzere wonse wozungulira kuchokera kumphuno ya meltblown zimafa kupita ku chipangizo cholandira sichikhoza kukhalabe bwino (monga kusinthasintha kwa mphamvu yotambasula ya kutentha kwakukulu ndi kuthamanga kwa mpweya, kuthamanga ndi kutentha kwa mpweya wozizira, ndi zina zotero), zomwe zimapangitsa kusiyana kwa ulusi wosungunuka.
Kufanana kwa fiber diameter mu ukonde wa spunbond nonwoven fabric ndikwabwinoko kuposa ulusi wosungunuka, chifukwa mumayendedwe opota, mikhalidwe yozungulira imakhala yokhazikika, ndipo mikhalidwe yotambasula ndi yozizirira imasinthasintha kwambiri.
Kuyerekeza kwa Digiri ya Crystallization ndi Oriental
Kuwoneka bwino kwa ulusi wosungunuka ndi kupendekeka kwa ulusi wosungunuka ndi wocheperako kuposa ulusi wa spunbond. Chifukwa chake, kulimba kwa ulusi wowombedwa ndi chitsulo kumakhala kocheperako, komanso kulimba kwa ukonde wa ukonde nakonso kumakhala kocheperako. Chifukwa cha kusalimba kwa ulusi wa ulusi wosungunula wansalu zowombedwa bwino, kugwiritsa ntchito kwenikweni kwa nsalu zosungunula zowombedwa kumadalira mawonekedwe a ulusi wawo wapamwamba kwambiri.
Kuyerekeza pakati pa ulusi wopota wosungunuka ndi ulusi wa spunbond
A, Fiber kutalika - spunbond ndi ulusi wautali, meltblown ndi ulusi waufupi
B, Mphamvu za CHIKWANGWANI - spunbond CHIKWANGWANI mphamvu>mphamvu CHIKWANGWANI chosungunuka
Fiber fineness - Ulusi wosungunuka ndi wabwino kuposa ulusi wa spunbond
Zochitika zosiyanasiyana zogwiritsira ntchito
Magawo ogwiritsira ntchito a spunbond ndi meltblown nawonso ndi osiyana. Kawirikawiri, nsalu za spunbond zimagwiritsidwa ntchito makamaka pazinthu zaukhondo ndi mafakitale, monga zopukutira zaukhondo, masks, nsalu zosefera, ndi zina zotero. Nsalu za Meltblown zimagwiritsidwa ntchito makamaka pazinthu zachipatala, masks ndi madera ena. Chifukwa cha mawonekedwe awoonda komanso owundana, nsalu zosungunuka zimakhala ndi zosefera bwino ndipo zimatha kusefa bwino tinthu tating'onoting'ono ndi tinthu ta virus.
Kuyerekeza mtengo pakati pa spunbond ndi meltblown
Pali kusiyana kwakukulu pamitengo yopangira pakati pa spunbond ndi meltblown. Mtengo wopangira spunbond ndi wokwera chifukwa umafunikira mphamvu zambiri ndi zida zamagetsi. Pa nthawi yomweyi, chifukwa cha ulusi wochuluka, nsalu zopangidwa ndi spunbond zimakhala ndi dzanja lolimba ndipo zimakhala zovuta kuti zivomerezedwe ndi msika.
M'malo mwake, mtengo wopangira meltblown ndi wotsika kwambiri chifukwa ukhoza kuchepetsa ndalama kudzera mukupanga kwakukulu komanso makina opangira makina. Panthawi imodzimodziyo, chifukwa cha ulusi wabwino kwambiri, nsalu zosungunuka zimakhala ndi zofewa komanso zomveka bwino, zomwe zingathe kukwaniritsa zofuna za msika.
【Mapeto】
Meltblown nonwoven nsalu ndispunbond nonwoven nsalundi mitundu iwiri yosiyana ya zinthu nonwoven ndi njira zosiyanasiyana kupanga ndi makhalidwe. Pankhani ya kugwiritsa ntchito ndi kusankha, ndikofunikira kuganizira mozama za zosowa zenizeni ndi mawonekedwe a kagwiritsidwe ntchito, ndikusankha zinthu zoyenera kwambiri zomwe sizinalukidwe.
Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
