Makhalidwe ndi ubwino wa nsalu za polypropylene spunbond zopanda nsalu, polypropylene spunbond nsalu zopanda nsalu ndi mtundu wa nsalu zopanda nsalu..Chifukwa njira yaukadaulo ndiyosavuta, zotulutsa zake ndi zazikulu, ndipo sizowopsa komanso zopanda vuto kwa thupi la munthu.Choncho, amagwiritsidwa ntchito kwambiri pazinthu zaukhondo, ndi zina.
Mbali ndi Ubwino
Chifukwa chofunikira chakukula mwachangu kwa njira ya spunbond ndikuti imagwiritsa ntchito ma polima opangira ngati zida.Njirayi imagwiritsa ntchito mfundo ya kupota kwa mankhwala.Pozungulira polima, ma filaments osalekeza amamangiriridwa mwachindunji pambuyo popota.Nsalu zopanda nsalu, njira yopangira ndi yosavuta komanso yachangu.Poyerekeza ndi ukadaulo wowuma wopanda nsalu, umapulumutsa njira zingapo zotopetsa zapakatikati monga kupiringa kwa ulusi, kudula, kulongedza, mayendedwe, kusakaniza ndi makhadi.Chofunikira kwambiri pakupanga zinthu zambiri ndikuti zinthu za spunbond zitha kuchepetsedwa mtengo, kukhazikika bwino, komanso kupikisana kwambiri pamsika.Atha kulowa pamsika wa nsalu, mapepala ndi mafilimu muzogwiritsa ntchito zosiyanasiyana zotayidwa komanso zolimba.Kachiwiri, popeza nsalu zopanda nsalu za spunbond zimagwiritsa ntchito kuchuluka kwa polypropylene monga zopangira zazikulu, zimakhala ndi ubwino wambiri pamtengo, ndondomeko yopangira, mtengo wopanga, ndi zina zotero, zomwe zimalimbikitsanso kwambiri chitukuko chokhazikika cha spunbond makampani opanga nsalu.Komanso, spunbond nonwoven mankhwala ndi katundu mawotchi kwambiri, ndi mphamvu kumakoka, elongation pa yopuma, misozi mphamvu ndi zizindikiro zina kuposa youma, yonyowa, ndi meltblown nonwovens, makamaka m'zaka zaposachedwapa, spunbond Kukula mofulumira kupanga mzere sikelo, ukadaulo ndi zida ndi chitukuko cha msika wazinthu zakulitsa kwambiri ntchito ya nsalu za spunbond zosalukidwa.
Kusiyana kwakukulu pakati pa kupanga spunbonding ndi kupota kwa mankhwala ulusi ndi kugwiritsa ntchito mpweya draft ndi mwachindunji ukonde mapangidwe.Chifukwa chake, kulemba kwa spunbonding kwakhala vuto lalikulu laukadaulo.M'mbuyomu, kukonza makina kumagwiritsidwa ntchito.Wokhuthala komanso wosakhazikika.Pakadali pano, zida zopangira spunbond padziko lonse lapansi zatengera ukadaulo wojambula mpweya.Chifukwa cha njira zosiyanasiyana zojambulira mpweya, pali mitundu itatu yopangira mizere ya spunbond, yomwe ndi tubular drafting, wide-slot drafting, ndi yopapatiza-slot drafting.Wonjezerani ndi zina zotero.
Ukadaulo wopanda nsalu wa Spunbond wakhala ukukulitsa luso la mzere wopanga ndikuthana ndi zovuta zofananira, kuphimba ndi dzanja loyipa la nsalu zopanda nsalu, kuti apititse patsogolo mphamvu, kufewa, kufananiza ndi chitonthozo cha spunbond nsalu., hygroscopicity ndi zina.
