Ndi zinthu ziti zomwe zimagwiritsidwa ntchito kwambiri pansalu ya mask meltblown

Nsalu ya Meltblown ndi zinthu zosefera zomwe zimasungunula polypropylene ndi zida zina pa kutentha kwakukulu, zimapanga ulusi wabwino kudzera pakupota, kenako ndikupanga wosanjikiza wosefera kudzera mu stacking yachilengedwe kapena electrostatic adsorption. Kusiyana kwa ulusi wa chigoba cha nsalu yosungunuka ndi yaying'ono, kusefera kwachangu ndikokwera, ndipo kumatha kuletsa tinthu tating'onoting'ono ndi madontho. Kuphatikiza apo, nsalu zosungunuka zimathanso kuthandizidwa ndi electrostatic kuti ziwonjezere kusefa bwino.

Chitetezo cha masks opangidwa ndi nsalu zosungunuka

Chigoba chansalu chosungunula chosawomba chimaphatikiza ubwino wa nsalu zopanda nsalu ndi nsalu yosungunuka, kuonetsetsa chitonthozo pamene akupereka kusefera koyenera. Mukasankhidwa ndikugwiritsidwa ntchito moyenera, masks amtunduwu ndi otetezeka. Amatha kutsekereza ma virus, mabakiteriya, ndi zinthu zina zovulaza mumlengalenga, kuteteza thanzi la kupuma kwa ogwiritsa ntchito.

Komabe, ziyenera kuzindikirika kuti chitetezo cha masks chimadaliranso momwe amavalira komanso malo omwe amagwiritsidwa ntchito. Ogwiritsa ntchito awonetsetse kuti chigobacho chikugwirizana mwamphamvu ndi nkhope zawo kuti asatayike; Panthawi imodzimodziyo, m'madera omwe ali ndi chiopsezo chachikulu monga zipatala ndi madera omwe ali ndi miliri yoopsa, masks okhala ndi chitetezo chokwanira ayenera kusankhidwa.

Zomwe zimagwiritsidwa ntchito popanga chigoba chosungunuka

Nsalu yosungunuka ya chigoba nthawi zambiri imapangidwa ndi ukadaulo wa meltblown, womwe umatha kutentha ndi kusungunula pulasitiki ya polypropylene kapena mapulasitiki ena oyenera a thermoplastic, kuwapanga kudzera pa spinneret, kenako kugwiritsa ntchito kuziziritsa, kuchiritsa, kusindikiza ndi njira zina zopangira kuti apange chinthu chofunikira chosungunuka. Chifukwa chake, zida zomwe zimagwiritsidwa ntchito kwambiri pansalu yosungunuka ya chigoba makamaka imaphatikizapo pulasitiki ya polypropylene, PET, ndi zina.

Pakati pawo, pulasitiki ya polypropylene ndi imodzi mwazinthu zodziwika bwino za nsalu yosungunuka ya chigoba, yomwe ili ndi mawonekedwe a kuwala, woonda, mpweya wabwino, komanso kusefera kwakukulu. Choncho, amagwiritsidwa ntchito kwambiri m'mafakitale monga masks ndi zovala zoteteza. Kuphatikiza apo, zida zina zoyenera za thermoplastic zitha kugwiritsidwanso ntchito ngati zida zopangira nsalu zosungunuka za chigoba, ndipo kusankha kwapadera kuyenera kutengera zosowa zosiyanasiyana.

Zida zina zosungunula chigoba ndi njira

Kuphatikiza pa pulasitiki ya polypropylene yomwe imagwiritsidwa ntchito kwambiri pansalu yosungunuka ya chigoba, zida zosungunuka za chigoba zimaphatikizanso zigawo zothandizira, zosefera, ndi zigawo zoteteza. Mwachindunji, gawo lothandizira limapangidwa ndi ulusi wosagwirizana ndi kutentha kwambiri komanso wosawononga dzimbiri monga ulusi wa polyester ndi nayiloni, pomwe gawo losefera limapangidwa ndi ulusi monga polypropylene ndi PBT. Chotetezacho chimagwiritsidwa ntchito makamaka pogwiritsa ntchito njira monga electrostatic melting spray ndi microporous membrane.

Kuphatikiza apo, pakugwiritsa ntchito ukadaulo wa mask meltblown, ndikofunikira kulingalira nkhani monga kusankha ndikusintha mawonekedwe a nozzle. Mwachitsanzo, magawo monga kabowo, kadanga, ndi liwiro la spinneret amatha kukhudza mtundu womaliza wa nsalu yosungunuka. Choncho, muzogwiritsira ntchito, zosintha ziyenera kupangidwa malinga ndi zosowa zosiyanasiyana.

Chidule

Zopangira zomwe zimagwiritsidwa ntchito kwambiri pansalu yosungunuka ya chigoba, pulasitiki ya polypropylene, imakhala ndi mpweya wabwino komanso kusefera, motero imagwiritsidwa ntchito kwambiri m'mafakitale monga masks ndi zovala zoteteza. Kuphatikiza pa pulasitiki ya polypropylene, zida zina zoyenera za thermoplastic zitha kugwiritsidwanso ntchito ngati zopangira, ndipo zida ndi njira monga zigawo zothandizira, zosefera, ndi zigawo zoteteza ziyenera kugwiritsidwa ntchito.

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 ku 9 magalamu mpaka 300 magalamu.
