Nsalu yosalukidwa imaphwanya mfundo yachikhalidwe ya nsalu, ndipo ili ndi makhalidwe monga kuyenda kwafupikitsa kwa ntchito, kupanga mwachangu, kutulutsa kwakukulu, mtengo wotsika, kugwiritsidwa ntchito kwambiri, komanso magwero osiyanasiyana a zipangizo zopangira.
Nsalu zosalukidwa ndi singanondi mtundu wa nsalu zosalukidwa, zomwe zimapangidwa ndi zinthu zopangira polyester, polyester, ndi polypropylene, ndipo zimakonzedwa kudzera mu kubowola singano zingapo ndikukanikiza bwino kutentha. Malinga ndi njira zosiyanasiyana, ndi zipangizo zosiyanasiyana, zinthu zikwizikwi zimapangidwa, zomwe zimagwiritsidwa ntchito m'mbali zonse za moyo, ndipo zinthu zosiyanasiyana zimatha kusinthidwa malinga ndi zolinga zosiyanasiyana.
Pulogalamu yokonza
Amapangidwa ndi zinthu zopangira polyester ndi polypropylene ndipo amapakidwa, kupesa, kuyikapo singano, komanso makamaka singano. Pakati pake pali nsalu ya maukonde, kenako kudzera mu nsalu yopangidwa ndi ma nucleation awiri, yopangidwa ndi mpweya komanso yobowoledwa ndi singano, nsalu yosindikizira pambuyo pake imakhala ndi mawonekedwe atatu. Pambuyo potentha ndi kuwotcha, pamwamba pake pamakhala mafuta ambiri kuti apange nsalu yosakaniza. Pamwamba pake pamakhala posalala, ndipo ma micropores amagawidwa mofanana. Kuchokera pamwamba, chinthucho chimakhala ndi malo okhuthala bwino, osalala komanso opumira mpweya mbali zonse ziwiri. Zatsimikiziridwa kuti fyuluta yomwe ili pa mbale ndi compressor ya chimango imatha kugwiritsa ntchito mphamvu yamphamvu kwambiri ndipo kulondola kwa kusefa ndi mpaka ma microns 4. Pakufunika kupereka mitundu iwiri ya zinthu zopangira polypropylene ndi polyester. Makhalidwe awonetsa kuti nsalu yosakaniza yopanda ulusi imagwira ntchito bwino kwambiri mu press ya mbale ndi chimango: mwachitsanzo, kuchiza ndi matope m'mafakitale okonzekera malasha ndi kuchiza madzi otayira m'mafakitale achitsulo ndi zitsulo. Mu fakitale yopangira mowa, kusindikiza ndi kuyika utoto m'mafakitale opangira utoto, kuchiza madzi otayira. Ngati nsalu yosefera ya zinthu zina ikugwiritsidwa ntchito, keke yosefera sidzakhala youma komanso yovuta kugwa. Mukagwiritsa ntchito nsalu yosefera yosalukidwa, keke yosefera idzakhala youma kwambiri pamene mphamvu ya sefa ifika pa 10kg-12kg, ndipo keke yosefera idzatsegulidwa fyuluta ikayikidwa mu frame. Idzagwa yokha. Ogwiritsa ntchito akasankha nsalu zosefera zosalukidwa, amaganizira kwambiri nsalu zosefera zosalukidwa za makulidwe ndi khalidwe losiyana malinga ndi momwe mpweya umalowera, kulondola kosefera, kutalika, ndi zina zotero, magawo azinthu, chonde dinani polyester needled felt ndi polypropylene needled felt, specifications ndi mitundu yonse ndi Izi zitha kupangidwa.
Mndandanda wansalu zosalukidwa ndi singanoAmapangidwa kudzera mu kuyika bwino ma carding, kubowola singano molondola kwambiri kapena kuponda bwino kutentha. Pogwiritsa ntchito njira ziwiri zopangira acupuncture zolondola kwambiri kunyumba ndi kunja, ulusi wapamwamba umasankhidwa. Kudzera mu mgwirizano wa njira zosiyanasiyana zopangira komanso kuphatikiza zipangizo zosiyanasiyana, zinthu zambirimbiri zikugulitsidwa pamsika, makamaka kuphatikizapo: geotextile, geomembrane, nsalu ya velvet, bulangeti lolankhulira, bulangeti lamagetsi, thonje losokedwa, thonje la zovala, ntchito zamanja za Khirisimasi, nsalu yoyambira ya chikopa cha munthu, nsalu yapadera yopangira zosefera.
Mfundo yogwiritsira ntchito
Kupanga nsalu zosalukidwa pogwiritsa ntchito njira ya acupuncture kumachitika kokha kudzera mu makina, ndiko kuti, kuboola kwa makina oboola singano, komwe kumalimbitsa ukonde wa ulusi wofewa ndikupeza mphamvu. Mfundo yaikulu ndi iyi:
Gwiritsani ntchito m'mphepete mwa magawo atatu (kapena m'mbali zina) zokhala ndi minga yopingasa kuti muboole ukonde wa ulusi mobwerezabwereza. Pamene minga imadutsa mu ukonde, imakakamiza pamwamba ndi mkati mwa ukonde kuti zilowe mkati mwa ukonde. Chifukwa cha kukangana pakati pa ulusi, ukonde woyambirira wopindika umakanikizidwa. Pamene singano yodula ituluka mu ukonde wa ulusi, minga yopindika ya ulusi imachoka pa mingayo ndikukhala mu ukonde wa ulusi. Mwanjira imeneyi, mingayo yambiri ya ulusi imakoka ukonde wa ulusi kotero kuti sungathenso kubwezeretsa momwe unalili wopindika poyamba. Pambuyo poboola singano kambirimbiri, mingayo yambiri ya ulusi imabooledwa mu ukonde wa ulusi, zomwe zimapangitsa ulusi womwe uli mu ukonde wa ulusi kukanganirana, motero amapanga chinthu chosalukidwa ndi singano chokhala ndi mphamvu ndi makulidwe enaake.
Mitundu ya njira yosaluka yobowoledwa ndi singano imaphatikizapo kuyika singano patsogolo, kuyika singano yaikulu, kuyika singano pa chitsanzo, kuyika singano ya mphete ndi kuyika singano ya tubular.
Kuti mudziwe zambiri komanso upangiri waukadaulo pa nsalu yosalukidwa ndi Melt-blown,Chopangidwa Chosapangidwa ndi Ulusi, Nsalu Yopanda Ulusi ya Spunlace, Sefani Nsalu Yopanda Ulusi, Chopanda nsalu chopangidwa ndi singano, mwalandiridwa kuti mulumikizane ndi Jinhaocheng Nonwoven Fabric. Tidzayesetsa kukuthandizani.
