Chifukwa chiyani masks amalepheretsa kufalikira kwa kachilomboka?

Ndi zinthu zotani?

Nthawi zambiri timanena kuti masks amapangidwa ndi nsalu zopanda nsalu.Nsalu zopanda nsalu ndi nsalu zopanda nsalu, zotsutsana ndi nsalu, zomwe zimapangidwa ndi ulusi wolunjika kapena mwachisawawa.
Pankhani ya masks, zopangira ndi Polypropylene (PP).Masks omwe amatha kutaya nthawi zambiri amakhala a Multilayered Polypropylene.Dzina la Chingerezi: Polypropylene, PP mwachidule, ndi yopanda mtundu, odorless, sanali poizoni, translucent olimba mankhwala, amene ndi polima pawiri wopangidwa ndi polymerization wa propylene.Polypropylene imagwiritsidwa ntchito kwambiri popanga zinthu za fiber monga zovala ndi mabulangete, zida zachipatala, magalimoto, njinga, zida zosinthira, mapaipi oyendera ndi zotengera zamankhwala, komanso m'matumba a chakudya ndi mankhwala.
Nsalu yopanda nsalu yopangidwa ndi nsalu yapadera ya polypropylene yopanda nsalu imatha kugwiritsidwa ntchito ngati zovala zotayidwa, ma sheet, masks, zophimba, mayamwidwe amadzimadzi komanso zina zamankhwala ndi zaumoyo.

Masks omwe amadziwika kuti ali ndi zoteteza pa coronavirus yatsopano makamaka amaphatikiza masks oteteza otayika ndi masks a N95.Zosefera zazikulu za masks awiriwa ndizabwino kwambiri, electrostatic fyuluta lining - kusungunula-wowombedwa sanali nsalu nsalu.Sungunulani zowombedwa sanali nsalu nsalu makamaka zopangidwa polypropylene, ndi mtundu wa ultrafine electrostatic CHIKWANGWANI nsalu, akhoza kugwira fumbi.
Madontho okhala ndi kachilombo ka chibayo pafupi ndi sungunula-wowomberedwa sanali nsalu nsalu adzakhala electrostatic adsorption pamwamba pa nsalu sanali nsalu, sangathe kudutsa, iyi ndi mfundo ya izi. zinthu kudzipatula mabakiteriya.Pambuyo fumbi kugwidwa ndi ultrafine electrostatic CHIKWANGWANI, n'kovuta kwambiri kulekanitsa ndi kuyeretsa, ndipo kutsuka kuwononga electrostatic fumbi kusonkhanitsa luso, kotero chigoba ichi chingagwiritsidwe ntchito kamodzi kokha.

Masks oteteza omwe amatha kutaya nthawi zambiri amapangidwa ndi zigawo zitatu za nsalu zosalukidwa.Zinthuzo ndi nsalu zosalukidwa zosalukidwa + zosungunula zosalukidwa + ndi nsalu zosalukidwa zosalukidwa.
Magawo angapo a masks sanatchulidwe mu standard standard GB/T 32610 ya masks.Pa masks azachipatala, payenera kukhala magawo atatu, omwe amatchedwa SMS (2 zigawo za S ndi 1 wosanjikiza wa M).
Chiwerengero chapamwamba kwambiri cha zigawo ku China panopa ndi 5 zigawo, zomwe zimatchedwa SMMMS (2 zigawo za S ndi 3 zigawo za M).Apa S imayimira Spunbond wosanjikiza (Spunbond), ulusi wake wapakati ndi wokhuthala, pafupifupi 20 microns (μm), udindo waukulu wa zigawo za 2 za S Spunbond ndizothandizira nsalu zonse zopanda nsalu, ndipo sizikhala ndi zotsatira zambiri pa chotchinga.Chinthu chofunika kwambiri mu mask ndi chotchinga chotchinga kapena chotchinga cha Meltblown M (Meltblown).
Makulidwe a ulusi wa Meltblown wosanjikiza ndiabwino, pafupifupi ma microns 2 (μm), omwe amathandizira kwambiri kuteteza mabakiteriya ndi magazi kuti asalowe. mu izo.Ngati zigawo za S spun-bonded zachuluka, chigoba chimakhala cholimba, ndipo chosanjikiza chopopera M chochuluka, kupuma kumakhala kovuta, kotero kuchokera kumasuka kwa masks opumira mpaka kuwunika momwe masks akudzipatula, kupuma kwambiri. zovuta, kutsekereza zotsatira ndi bwino, koma, ngati M wosanjikiza mu filimu, kwenikweni musapume momasuka, kachilombo wadulidwa, koma anthu sangathe kupuma.N95 kwenikweni ndi chigoba chosanjikiza 5 chopangidwa kuchokera ku polypropylene nonwoven SMMMS chomwe chimasefa mpaka 95% ya tinthu tating'onoting'ono.

Chifukwa chake, tidapeza kuti masks omwe amatha kupatulira kachilomboka ayenera kukhala opangidwa ndi zida zapadera, ndipo sizinthu zonse zomwe zili zoyenera masks.
Pomaliza, ife ORIENTMED tikukhulupirira moona mtima aliyense atha kukhala otetezeka komanso athanzi.
