Nsalu ya Spunbond yosawomba + imasungunula nsalu yopanda nsalu + yowombedwa ndi spunbond yopanda nsalu

Zofotokozera za masks azachipatala nthawi zambiri zimatengera magawo atatu, okhala ndi zida kuphatikizansalu ya spunbond yopanda nsalu, nsalu zosalukidwa zosungunuka, ndi nsalu za spunbond zosalukidwa. Chifukwa chachikulu chosankha nsalu zopanda nsalu monga zakuthupi ndi chifukwa chakuti ndizopepuka komanso zimakhala ndi zosefera zabwino, zomwe zakhala chinthu chachikulu chopangira chigoba.

Nsalu zophatikizika zosalukidwa

Zingwe zazifupi zitha kugwiritsidwanso ntchito pagawo limodzi kuti khungu liwoneke bwino, lomwe ndi nsalu yotentha ya ES yotentha yopanda nsalu + yosungunuka yopanda nsalu + spunbond yopanda nsalu. Thewosanjikiza wakunja wa chigobaadapangidwa kuti ateteze madontho, wosanjikiza wapakati amasefedwa, ndipo kukumbukira kumatenga chinyezi. Nsalu za Meltblown nthawi zambiri zimasankhidwa kuti zizilemera magalamu 20. Chigoba chamtundu wa chikho cha N95 chimapangidwa ndi thonje lokhomeredwa ndi singano, nsalu yosungunuka, komanso nsalu zosalukidwa. Nsalu yosungunuka nthawi zambiri imalemera magalamu 40 kapena kupitilira apo, ndipo ndi makulidwe a thonje wokhomeredwa ndi singano, imawoneka yokulirapo kuposa maski athyathyathya pamawonekedwe, ndipo chitetezo chake chimatha kufikira 95%.

Nsalu zosalukidwa za SMMS

N95 kwenikweni ndi chigoba cha 5-wosanjikiza chopangidwa ndi polypropylene yopanda nsalu SMMMS yomwe imatha kusefa 95% ya tinthu tating'onoting'ono.

Zopangira zopangira masks opangira opaleshoni

1. Nsalu zosalukidwa: Ichi ndi chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito popangira masks. Nsalu zosalukidwa nthawi zambiri zimapangidwa ndi ulusi wopangidwa monga ulusi wa poliyesitala, ulusi wa polypropylene, kapena ulusi wa nayiloni, womwe umadziwika ndi mpweya wabwino komanso kusefera kwabwino. Zopangira zopangira nsalu zopanda nsalu ndi polypropylene (PP).

2. Sungunulani nsalu yowombedwa: Nsalu yosungunula ndi mtundu wa nsalu zosalukidwa zomwe zimagwiritsa ntchito kupota kothamanga kwambiri kuti zipopera tinthu tating'onoting'ono ta polypropylene pa template kuti mupange ukonde wa ulusi, ndipo kudzera mu chithandizo cha electrostatic, ukonde wa fiber umapanga wosanjikiza wazosefera wokhala ndi zotsatira zabwino zosefera. Nsalu zosalukidwa za Meltblown zimagwiritsidwa ntchito ngati gawo lapakati kuti lizipatula fumbi ndi ma virus omwe ali mumlengalenga, kuwaletsa kuti asakowedwe mkamwa ndi mphuno.

3. Nsalu yosalukidwa: Nsalu yosalukidwa ndi mtundu wansalu wosalukidwa wopangidwa kuchokera ku ulusi wa polypropylene wotambasulidwa mosalekeza. Ili ndi mawonekedwe amphamvu kwambiri, kulemera kochepa, komanso kupuma bwino, ndipo imagwiritsidwa ntchito ngati gawo loteteza masks.

4. Nsalu yosungunuka yonyezimira: Ichi ndi chinthu chophatikizika chomwe chimaphatikiza nsalu yosungunuka ndi nsalu yopanda nsalu, yomwe imagwiritsidwa ntchito ngati chosefa cha masks azachipatala, omwe amatha kusefa bwino tinthu tating'onoting'ono ndi mabakiteriya.

5. Chojambula chapamphuno: Chimagwiritsidwa ntchito kutetezera mbali ya mphuno ya chigoba, chomwe nthawi zambiri chimapangidwa ndi pulasitiki kapena zitsulo.

6. Elastic band: amagwiritsidwa ntchito kukonza chigoba pamalo a nkhope, nthawi zambiri amapangidwa ndi latex kapena polyester fiber.

Njira yogwiritsira ntchito

Onetsetsani mosamala pakamwa panu ndi mphuno ndi chigoba ndikuchimanga mwamphamvu, kuchepetsa kusiyana pakati pa nkhope yanu ndi chigoba momwe mungathere;

Mukamagwiritsa ntchito, pewani kukhudza chigoba - mwachitsanzo, kuchotsa kapena kuyeretsa chigoba mukachigwira, sambani m'manja ndi sopo kapena kugwiritsa ntchito mankhwala oyeretsera m'manja opangidwa ndi mowa;

Pambuyo pa chigoba chitakhala chonyowa kapena kuipitsidwa ndi chinyezi, m'malo mwake ndi chigoba choyera ndi chowuma;

Osagwiritsanso ntchito masks omwe amatha kutaya. Masks otayika ayenera kutayidwa pambuyo pa ntchito iliyonse ndikutaya nthawi yomweyo atachotsedwa.

Ngakhale pali masks ena oti alowe m'malo mwa masks azachipatala (monga chigoba cha thonje, chotchingira kumutu, mapepala amaso, zotchingira mphuno ndi pakamwa), pali kusowa kwa chidziwitso chokhudza magwiridwe antchito azinthu zotere.

Ngati mugwiritsa ntchito zophimba zina zotere, zigwiritsidwe ntchito kamodzi kokha, kapena ngati ndi chigoba cha thonje, zitsukidwe bwino mukatha kugwiritsa ntchito nthawi iliyonse (mwachitsanzo, kuchapa ndi zotsukira m'nyumba kutentha kwa chipinda). Iyenera kuchotsedwa mwamsanga pambuyo poyamwitsa wodwalayo. Sambani m'manja mukangochotsa chigoba.

Nkhani ya Mask
