Kungani imaski ivimbela ukusabalala kwegciwane?
Luhlobo luni lwempahla?
Sivame ukusho ukuthi imaski yenziwe ngezindwangu ezingalukiwe.Izindwangu ezingezona eziboshwe ziyizindwangu ezingezona eziboshwe, ngokuphambene nezindwangu eziboshwe, ezenziwe ngemicu eqondile noma engahleliwe.
Uma kukhulunywa ngamamaski, impahla eluhlaza yiPolypropylene (PP).Amamaski alahlwayo ngokuvamile ane-multilayered Polypropylene.Igama lesiNgisi: I-Polypropylene, i-PP ngamafuphi, ayinambala, into eqinile engenaphunga, engeyona enobuthi, eshintshashintshayo, okuyinhlanganisela ye-polymer eyakhiwe yi-polymerization ye-propylene.I-Polypropylene isetshenziswa kabanzi ekukhiqizeni imikhiqizo ye-fiber njengezingubo nezingubo zokulala, amathuluzi ezokwelapha, izimoto, amabhayisikili, izingxenye eziyisipele, amapayipi okuthutha neziqukathi zamakhemikhali, kanye nokupakishwa kokudla nemithi.
Indwangu engalukiwe ekhiqizwa yindwangu ekhethekile ye-polypropylene engalukiwe ingasetshenziselwa izingubo zokusebenza ezilahlwayo, amashidi, imaski, izembozo, amaphedi okumunca uketshezi kanye ezinye izinsiza zokwelapha nempilo.
Imaski eyaziwa ngokuba nemiphumela yokuvikela ku-coronavirus yenoveli ikakhulukazi ihlanganisa imaski yokuzivikela elahlwayo kanye nemaski N95.Izinto zokuhlunga eziyinhloko zalezi zimaski ezimbili zinhle kakhulu, i-electrostatic filter lining - Indwangu engalukiwe encibilikile.Indwangu encibilikisiwe engalukiwe yenziwa ikakhulukazi nge-polypropylene, iwuhlobo lwendwangu ye-ultrafine electrostatic fiber, ekwazi ukuthwebula uthuli.
Amaconsi equkethe igciwane lenyumoniya eduze kwendwangu engalukiwe encibilikisiwe izoba yi-electrostatic adsorption ebusweni bendwangu engalukiwe, ayikwazi ukudlula, lesi yisimiso salokhu. amagciwane okuhlukanisa izinto ezibonakalayo.Ngemuva kokuthi uthuli lubanjwe yi-ultrafine electrostatic fiber, kunzima kakhulu ukuhlukaniswa ngokuhlanza, futhi ukugeza kuzobhubhisa ikhono lokuqoqa uthuli lwe-electrostatic, ngakho le mask ingasetshenziswa kanye kuphela.
Amamaski okuvikela alahlwayo ngokuvamile enziwa ngezingqimba ezintathu zendwangu engalukiwe.Indwangu engalukiwe ephothiwe + indwangu engalukiwe encibilikile + ephothiwe ngendwangu engalukiwe.
Izendlalelo ezimbalwa zamamaski azibekiwe ku-GB/T 32610 ejwayelekile kazwelonke yamamaski.Kumaski ezokwelapha, kufanele okungenani kube nezingqimba ezi-3, ezibizwa nge-SMS (izingqimba ezi-2 zika-S no-1 ungqimba luka-M).
Inani eliphakeme kakhulu lezendlalelo eShayina okwamanje yizendlalelo ezi-5, ezibizwa ngokuthi i-SMMMS (izingqimba ezi-2 zika-S nezingu-3 zika-M).Lapha i-S imele ungqimba lwe-Spunbond (Spunbond), ububanzi bayo befiber bukhulu kakhulu, cishe ama-microns angu-20 (μm), indima eyinhloko yezingqimba ze-2 ze-S Spunbond iwukusekela sonke isakhiwo sendwangu engalukiwe, futhi ayinawo umthelela omningi kusithiyo.Into ebaluleke kakhulu ngaphakathi kwe-mask ungqimba lwesithiyo noma ungqimba lwe-Meltblown M (Meltblown).
I-fiber diameter yongqimba lwe-Meltblown muhle uma kuqhathaniswa, cishe ama-microns angu-2 (μm), edlala indima ebalulekile ekuvimbeleni amagciwane kanye negazi ukuthi lingangeni. kuyo.Uma izingqimba eziboshwe nge-S ziningi ngokweqile, imaski iqinile, futhi isendlalelo sesifutho esingu-M kakhulu, ukuphefumula kunzima, ngakho-ke kusukela ekukhululekeni kokuphefumula imaski kuya ekuhlolweni komphumela wamaski wokuzihlukanisa, ukuphefumula okwengeziwe. kunzima, umphumela wokuvimbela ungcono, kodwa, uma ungqimba lwe-M lube yifilimu, ngokuyisisekelo ungaphefumuli ngokukhululekile, igciwane linqunywa, kodwa abantu abakwazi ukuphefumula.I-N95 empeleni iyimaski enezingqimba ezi-5 eyenziwe nge-polypropylene nonwoven SMMMS ehlunga kufikela ku-95% wezinhlayiya ezinhle.
Ngakho-ke, sithole ukuthi imaski engahlukanisa igciwane ngempela kufanele yenziwe ngezinto ezithile, futhi akuzona zonke izinto ezilungele imaski.
Okokugcina, sithemba ngobuqotho ukuthi wonke umuntu angazigcina uphephile futhi unempilo.
