Nsalu yosalukidwa yogwiritsidwa ntchito kuchipatala

Nsalu ya spunbonded polypropylene nonwoven imapangidwa ndi 100% polypropylene polima. Kutengera momwe amapangira, polypropylene ndi polymer yosunthika kwambiri yomwe imatha kupereka mikhalidwe yosiyanasiyana. Ulusi wa polypropylene umatulutsidwa ndikusanjidwa mwachisawawa pa lamba wonyamula ngati gawo la spunbonding. Pambuyo pake, ulusiwo umaphatikizidwa pamodzi pogwiritsa ntchito mpweya wotentha kapena calendering kuti apange nsalu yolimba komanso yowongoka.

Nonwoven spunbonded polypropylene nsalu ya masks pazifukwa zingapo

Chifukwa cha mawonekedwe ake a porous, omwe amalola kuti mpweya uziyenda uku akukhalabe ndi zotchinga zake, amatha kupuma kwambiri. Izi ndizofunikira kuti muchepetse kuchuluka kwa chinyezi ndikuwongolera chitonthozo chaovala.

Ndi yolimba koma yopepuka. Chifukwa cha kulemera kwake, polypropylene ya spunbond ili ndi mphamvu yabwino.

Chifukwa ndi hydrophobic, madzi ndi chinyezi zimathamangitsidwa nazo. Izi zimateteza ma virus ndi zinyalala mu chigoba ndikupangitsa kuti mawonekedwe ake akhalebe.

Ndi yotsika mtengo komanso yothandiza kupanga. Njira yopangira spunbonding ndiyothandiza kwambiri, ndipo utomoni wa polypropylene ndi wamtengo wapatali. Izi zimapangitsa kuti mtengo wopangira ukhale wotsika mtengo kwambiri.

Ndi yosinthika komanso yosinthika. Zakuthupi zimatha kukumbatira nkhope ndikuzikuta bwino.

Amapereka kuwongolera kwa tinthu kofunikira komanso kusefera. Kusefa bwino kwa tinthu tating'ono ting'onoting'ono kumatha kuchitika mwachisawawa chokhazikika komanso ulusi wabwino. Kuphatikiza apo, zosintha zina zoluka zimatha kupititsa patsogolo kusefa kwa tinthu tating'onoting'ono.

Zinthu izi zimapangitsa kuti nsalu ya polypropylene nonwoven yopangidwa ndi spunbonded ikhale chinthu chokondedwa kwambiri popanga masks amaso amtengo wapatali, okhalitsa komanso masks azachipatala. Itha kugwiritsidwanso ntchito ngati wosanjikiza woyambira molumikizana ndi zosefera za meltblown pomwe kusefera kowonjezereka kumafunika. Nsalu za polypropylene zosalukidwa ndizotsika mtengo, zogwiritsa ntchito zambiri, komanso zogwira mtima popanga masks ndi zida zamankhwala.

Zochitika ndi Zatsopano

Dziko la nsalu zopanda nsalu-kuphatikizapo PP spunbond-nthawi zonse likusintha chifukwa cha zatsopano zomwe zapezeka mu sayansi ndi zamakono. Zina mwa zochitika zodziwika bwino komanso zomwe zikuchitika m'tsogolomu ndi:

a. Mayankho Osasunthika: Kupanga nsalu zokhazikika zosawoloka kukukhala kofunika kwambiri pamene msika wa zinthu zoteteza chilengedwe ukukula. Izi zikuphatikizapo kuyang'ana njira zina zomwe zingathe compostable ndi biodegradable komanso kugwiritsa ntchito zipangizo zobwezerezedwanso kupanga PP spunbond.

b. Kuchita Kwakulitsidwa: Asayansi akuyesera kupanga nsalu zokhala ndi mphamvu zochulukirapo, zothamangitsa bwino zamadzimadzi, komanso mpweya wochulukirapo kuti apititse patsogolo magwiridwe antchito a PP spunbond. Izi zidzakulitsa kuchuluka kwa mafakitale omwe PP spunbond angagwiritsidwe ntchito.
