Nsalu zosalukidwa ndizodziwika kwambiri kuposa nsalu zosungunuka m'moyo watsiku ndi tsiku, monga zikwama zam'manja zopanda nsalu, mapepala okutira, ndi masks akunja, ndi zina zambiri. Kodi mutha kusiyanitsa bwino pakati pa mitundu iwiriyi ya nsalu?Ngati sichoncho, musadandaule, ndipo Hail Pereka Fone adzafotokoza zazikulu zinayi kusiyana pakati pawo.
Nsalu yosungunuka, yomwe imadziwikanso kuti nsalu yopanda nsalu yosungunuka, imangokhala gawo laling'ono la nsalu zopanda nsalu.Komabe, pali kusiyana kwakukulu pakati pa nsalu zosungunuka ndi zopanda nsalu, makamaka pazinthu zakuthupi, makhalidwe, ndondomeko ndi ntchito.
1. Zida zosiyanasiyana
Nsalu yosungunuka imapangidwa makamaka ndi polypropylene ndipo makulidwe ake a ulusi amatha kufika 1 ~ 5 microns.
Nsalu zosalukidwa, zomwe zimadziwikanso kuti thonje lokhomeredwa ndi singano kapena nsalu zosalukidwa ndi singano, nthawi zambiri zimapangidwa ndi ulusi wa poliyesitala ndi zida za poliyesitala ndipo zimapangidwa pogwiritsa ntchito makina a pp spunbond osawoka.
2. Makhalidwe osiyanasiyana
Ndi ma voids ochulukirapo, mawonekedwe a fluffy komanso kukana makwinya abwino, nsalu yosungunuka ili ndi mawonekedwe apadera a capillary a ulusi wabwino kwambiri wowonjezera kuchuluka ndi malo a ulusi pagawo lililonse, motero zimapangitsa kuti nsalu zosungunula zikhale zosefera bwino, zotchinga. , ndi mphamvu zoyamwa mafuta, zomwe zimapangitsa kuti zikhale zofunikira kwambiri za masks.
Nsalu yosalukidwa imakhala ndi mawonekedwe otsimikizira chinyezi, chopumira, chosinthika, chopepuka, chowotcha moto, chosakhala ndi poizoni komanso chosakoma, chotsika mtengo, komanso chobwezeretsanso, ndi zina zambiri.
3. Ntchito zosiyanasiyana
Nsalu zosungunula zimatha kugwiritsidwa ntchito m'magawo azinthu zosefera mpweya ndi madzi, zida zodzipatula, zida zoyamwitsa, zida za chigoba, zida zotulutsa mafuta ndi nsalu zopukutira.
Nsalu zopanda nsalu, poyerekeza ndi nsalu zosungunuka, zimagwiritsidwa ntchito kwambiri komanso zimagwiritsidwa ntchito.Zogulitsa zopanda nsalu ndi zokongola, zopepuka, zowongoka komanso zosinthidwanso ndi mawonekedwe ndi masitayilo osiyanasiyana, ndipo ndizoyenera filimu yaulimi, nsapato, zikopa, matiresi, zokongoletsera, mankhwala, zosindikizira, magalimoto, zomangira, mipando ndi mafakitale ena.
Mwachidule, nsalu zosungunuka ndizoyenera minda yapadera yokhala ndi miyezo yapamwamba, pamene nsalu zopanda nsalu zimakhala zowonjezereka kwambiri.
4. Njira zosiyanasiyana zopangira
Pankhani ya nsalu zosungunula, magawo a polima okhala ndi index yosungunuka kwambiri amachotsedwa ndikutenthedwa kuti asungunuke mu kutentha kwambiri kusungunuka ndi kutuluka kwabwino.Mtsinje wosungunula womwe umatulutsidwa kuchokera ku spinneret umawomberedwa kukhala ulusi wabwino kwambiri chifukwa cha kutentha kwambiri komanso kuthamanga kwa mpweya wotentha kwambiri, zomwe zimasonkhanitsidwa mu fiber network pa chipangizo cholandirira (monga makina osindikizira) ndikumangirirana wina ndi mzake kuti apange nsalu pogwiritsa ntchito kutentha kwake kotsalira.
Pali njira zambiri zopangira nsalu zosalukidwa, kuphatikiza spunbond, meltblown, hot-rolled and spunlace.Nsalu zambiri zopanda nsalu zomwe zili pamsika tsopano zimapangidwa ndipp spunbond makina opangira nsalu.Nthawi zambiri amagwiritsa ntchito magawo a polima, ulusi wokhazikika kapena ulusi mwachindunji kuti apange ukonde wa ulusi kudzera mumayendedwe a mpweya kapena makina, kenako ma hydroentanglement, kukhomerera singano, kapena kulimbitsa zopindika, ndikumaliza kupanga nsalu yosalukidwa.
