Ubwino wa PP spunbond sanali nsalu nsalu

Chifukwa chachikulu ntchito polypropylene monga zofunika zopangira spunbond sanali nsalu nsalu, ali zambiri ubwino mawu a mtengo, processing, mtengo kupanga, etc., amene kwambiri timapitiriza kukula kwa spunbond sanali nsalu nsalu katundu. Kuphatikiza apo, mawotchi azinthu za spunbond nonwovens ndiabwino kwambiri, okhala ndi zizindikiro monga kulimba kwamphamvu, kutalika panthawi yopuma, komanso kung'ambika kwamphamvu kuposa zowuma, zonyowa, ndi kusungunula nsalu zosawomba zowombedwa. Makamaka m'zaka zaposachedwa, spunbond yakula kwambiri potengera kukula kwa mzere wopanga, umisiri, zida, ndi msika wazinthu, kukulitsa kwambiri magwiridwe antchito a nsalu za spunbond nonwoven.

Kusiyana kwakukulu pakati pa kapangidwe ka njira ya spunbond ndi kupota kwa mankhwala opangidwa ndi ulusi wamagetsi ndiko kugwiritsa ntchito kujambula kwa mpweya ndi kupanga mwachindunji ukonde. Kukonzekera kwa njira ya spunbond kwakhala cholinga chaukadaulo. M'mbuyomu, kujambula kunkagwiritsidwa ntchito kuluka, zomwe zimapangitsa kuti ulusi wochuluka komanso kuyala ukonde kusakhale kofanana. Pakalipano, mayiko padziko lonse lapansi atengera njira yolembera mpweya mu zida zawo zopangira spunbond. Chifukwa cha kusiyana kwa kalembedwe ka kayendedwe ka mpweya, pali zinthu zitatu zosiyana pakupanga mizere yopangira spunbond, yomwe ndi chubu drafting, lalikulu ndi yopapatiza slit drafting, ndi yopapatiza slit drafting.

Nsalu za polypropylene zosalukidwa zimapangidwa kuchokera ku ma polima opangira ngati zida zopangira, ndipo njira iyi imayang'anira kupota kwa ulusi wamankhwala. Ulusi wautali umapitilizidwa mu njira yopota polima, ndipo pambuyo popopera mu ukonde, amamangiriridwa mwachindunji kuti apange nsalu zosalukidwa. Kupanga ndi kuluka ndizosavuta komanso zachangu, poyerekeza ndi njira zowuma zopanda nsalu zowuma, ndikuchotsa njira zingapo zotopetsa zapakatikati monga kupiringa kwa ulusi, kudula, kulongedza, kutumiza, kufananiza, ndi kupesa.

Chotsatira chofunikira kwambiri cha mtundu uwu wa kupanga mosalekeza komanso kuchuluka kwambiri ndikutsitsa mtengo wazinthu za spunbond, kukhalabe ndikhalidwe labwino, komanso kukhala ndi mpikisano wamphamvu wamsika. Atha kulowa mumsika wamsika wa nsalu, mapepala, ndi makanema pazinthu zosiyanasiyana zotayidwa komanso zokhazikika.
