Momwe mungasinthire kukana misozi kwa nsalu za spunbond nonwoven?

Kumene. Kupititsa patsogolo kukana kung'ambika kwa nsalu za spunbond nonwoven ndi pulojekiti yokhazikika yokhudzana ndi kukhathamiritsa kwazinthu zingapo, kuchokera kuzinthu zopangira ndi kupanga mpaka kumaliza. Kukana misozi ndikofunikira pachitetezo monga zovala zodzitchinjiriza, chifukwa zimakhudzana mwachindunji ndi kulimba kwa chinthucho komanso chitetezo chake chikakokedwa mwangozi ndi kuvulala.

Zotsatirazi ndi njira zazikulu zosinthira kukana misozi kwa nsalu za spunbond nonwoven:

Kukhathamiritsa kwa Zakuthupi: Kumanga Maziko Olimba

Kusankha Ma polima Olimba Kwambiri:

Kulemera Kwambiri kwa Mamolekyulu / Kuchepetsa Kulemera kwa Mamolekyulu a Polypropylene: Unyolo wautali wa mamolekyulu ndi kutsekeka kwakukulu kumabweretsa nyonga yayikulu komanso kulimba.

Copolymerization kapena Blending Kusintha: Kuonjezerapo pang'ono polyethylene kapena elastomers ku polypropylene. Kuyambitsa kwa PE kumatha kusintha mawonekedwe a crystallization, kuwongolera kusinthasintha komanso kukana kukhudzidwa, potero kumathandizira kukana misozi.

Kuonjezera Zosintha Zowonongeka: Kuyambitsa ma elastomer apadera kapena magawo a mphira chifukwa malo opanikizika amatha kuyamwa ndikubalalitsa mphamvu ya misozi, kuteteza kufalikira kwa ming'alu.

Kugwiritsa Ntchito Ma Fiber Apamwamba:

PET ndiPP Composites: Kuyambitsa ulusi wa poliyesitala panthawi ya spunbonding. PET, yokhala ndi modulus yayikulu komanso mphamvu, imakwaniritsa ulusi wa PP, kupititsa patsogolo mphamvu zonse za netiweki ya fiber.

Kugwiritsa ntchito ulusi wa bicomponent, monga "chilumba-chilumba" kapena "core-sheath". Mwachitsanzo, kugwiritsa ntchito PET ngati "core" ya mphamvu ndi PP ngati "sheath" yomatira kutentha, kuphatikiza ubwino wa zonsezi.

Kuwongolera Njira Yopanga: Kukometsa Mapangidwe a Fiber Network

Ichi ndiye gawo lofunikira kwambiri pakuwongolera kukana misozi.

Njira zopota ndi kujambula:

Kupititsa patsogolo Mphamvu za Fiber: Kupititsa patsogolo liwiro lojambula ndi kutentha kumapangitsa kuti thupi likhale lokhazikika komanso crystallization ya macromolecules a polima, zomwe zimapangitsa kuti zikhale zamphamvu kwambiri, zapamwamba-modulus monofilament fibers. Ma monofilaments amphamvu ndi maziko a nsalu zolimba.

Kuwongolera Fiber Fineness: Kuwonetsetsa kuti kukhazikika kwapangidwe, kuchepetsa m'mimba mwake moyenerera kumawonjezera kuchuluka kwa ulusi pagawo lililonse, kupangitsa kuti fiber network ikhale yolimba komanso kulola kugawa bwino katundu pansi pa kupsinjika.

Njira Zopangira Webusaiti ndi Zowonjezera:

Kupititsa patsogolo Kukhazikika kwa Fiber Mwachisawawa: Kupewa kulumikizana mopitilira muyeso wa unidirectional fiber. Kukhathamiritsa kwaukadaulo wopanga ma intaneti kumapanga isotropic fiber network. Mwanjira iyi, mosasamala kanthu komwe mphamvu yong'amba ikupita, ulusi wambiri wodutsa umakaniza, zomwe zimapangitsa kuti misozi ikhale yolimba.

Njira Yokometsera Yotentha Yotentha:

Mapangidwe a Bond Point: Kugwiritsa ntchito njira yosinthira "kadontho kakang'ono kodzaza". Zing'onozing'ono, zomangira zomangira zimatsimikizira mphamvu zokwanira zomangira popanda kusokoneza kwambiri kupitiriza kwa ulusi, kumabalalitsa bwino nkhawa mkati mwa ukonde waukulu wa fiber ndikupewa kupsinjika maganizo.

Kutentha ndi Kupanikizika: Kuwongolera bwino kutentha kwa kutentha ndi kupanikizika kumatsimikizira kusakanikirana kwa ulusi pamalo omangira popanda kupanikizika kwambiri komwe kungathe kuwononga kapena kusokoneza ulusi womwewo.

Kulimbitsa kwa Hydroentangling: Pazinthu zina, hydroentangling imagwiritsidwa ntchito ngati m'malo kapena kuwonjezera pakugudubuza kotentha. Kuthamanga kwa madzi othamanga kwambiri kumapangitsa kuti ulusi umangike, kupanga mawonekedwe atatu omangika pamakina. Kapangidwe kameneka kamagwira ntchito bwino kwambiri pakukana misozi ndipo kumapangitsa kuti pakhale chinthu chofewa.

Kumaliza ndi Kuphatikizika Ukadaulo: Kuyambitsa Kulimbikitsa Kwakunja

Lamination/Composite Technology:

Iyi ndi imodzi mwa njira zolunjika komanso zothandiza. Nsalu ya Spunbond yopanda nsalu imapangidwa ndi ulusi, nsalu yoluka, kapena nsalu ina ya spunbond yokhala ndi mawonekedwe ena.

Mfundo Yofunika Kuiganizira: Ulusi wamphamvu kwambiri mu mesh kapena nsalu yolukidwa imapanga mafupa olimba kwambiri omwe amalepheretsa kufalikira kwa misozi. Izi ndizomwe zimagwiritsidwa ntchito kwambiri pazovala zotchinga zotchinga kwambiri, pomwe kukana misozi kumachokera pazowonjezera zakunja.

Kumaliza kwa Impregnation:

The spunbond nsalu ndi impregnated ndi oyenera polima emulsion ndiyeno anachiritsa pa CHIKWANGWANI mphambano. Izi zimawonjezera mphamvu yolumikizana pakati pa ulusi, motero kumapangitsa kuti misozi ikhale yolimba, koma imatha kupereka kufewa komanso kupuma.

Mwachidule ndi Mfundo zazikuluzikulu

Kuti muchepetse kung'ambika kwa nsalu za spunbond nonwoven, njira yamitundu yambiri imafunikira:

Level | Njira | Core Role

Zida Zopangira | Gwiritsani ntchito ma polima olimba kwambiri, kusintha kophatikiza, kuwonjezera ma elastomer | Limbikitsani mphamvu ndi kukulitsa kwa ulusi womwewo

Njira Yopanga | Konzani kulemba, kupanga isotropic ulusi ulusi, kukhathamiritsa otentha akugudubuzika/hydroentangling njira | Pangani dongosolo lolimba, lofanana la fiber network ndi kufalikira kwabwino kwa nkhawa

Kumaliza | Laminate ndi ulusi, impregnate | Yambitsani njira zolimbikitsira kunja kuti mupewe kung'ambika

Lingaliro lalikulu sikuti limangopangitsa kuti ulusi uliwonse ukhale wolimba, komanso kuonetsetsa kuti dongosolo lonse la fiber network lingathe kumwazikana bwino ndikuyamwa mphamvu poyang'anizana ndi mphamvu zowonongeka, m'malo molola kuti kupanikizika kukhazikike ndikufalikira mofulumira pa mfundo imodzi.

Pakupanga kwenikweni, kuphatikiza koyenera kwambiri kuyenera kusankhidwa potengera momwe chinthucho chimagwirira ntchito, bajeti yamtengo wapatali, komanso magwiridwe antchito (monga kutulutsa mpweya ndi kufewa). Mwachitsanzo, pazovala zoteteza mankhwala owopsa kwambiri, masangweji opangidwa ndi "nsalu yamphamvu kwambiri ya spunbond + filimu yotchinga kwambiri + mesh reinforcement wosanjikiza" ndiye muyezo wagolide womwe umathandizira panthawi imodzi kukwaniritsa misozi yayikulu, kukana kuphulika ndi chitetezo chamankhwala.

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 pa 9 magalamu mpaka 300 magalamu.
