Indlela yokukhetha imaski efanelekileyo
Ukuqonda i-ASTM F2100-19 / EN14683: IMIGANGATHO KA-2019
Ukukhetha imaski efanelekileyo yenkqubo ethile licandelo elibalulekileyo leSixhobo soKhuseleko soBuqu ( PP ) protocol .Nangona iimaski zinokujongeka zifana , imaski nganye inomahluko obonakalayo ochaphazela umgangatho kunye nenqanaba lokuhluza .Ukuqonda inqanaba lokusebenza kwe-ASTM yemaski yobuso nganye kunokunceda ukwenza inkqubo yokukhetha ibe lula kwaye uqinisekise ukuba imaski yakho iya kubonelela ngokuhluzwa okufanelekileyo.
Imathiriyeli yemaski yobuso bezonyango egqunywe phantsi kweenkcukacha ze-ASTM zonyulwa njengenye okanye ngaphezulu kulawa manqanaba okusebenza alandelayo ngokusekwe kwiipropathi zesithintelo sezinto ezisetyenziswayo:

Igazi leSynthritic* imele ukuxhathisa kwemaski ekungeneni ngegazi lokwenziwa phantsi koxinzelelo ( mmhg ).Ilinganisa amandla okwakhiwa kwemathiriyeli yemaski ukunciphisa ukugcwala kolwelo oluhamba ngemathiriyeli enokuthi idibane nomntu oyinxibileyo.Ukuphakama kokuchasana kwamanzi ( ukuhluzwa ), ngcono ukhuseleko
I-BFE (uFanelo loHlulo lweBhaktiriya)imele ipesenti ye-aerosol particulates ehluzwe kubungakanani be-3 microns.Ngumlinganiselo wokusebenza kakuhle kwemaski ekuhluzeni iibhaktheriya ezidlula kuyo
PFE ( I-Sub-micron Particulate Filtration Efficiency)imele ipesenti ye-submicron particulates ehluzwe kwi-0.1 micron PFE ngumlinganiselo wempumelelo yemaski ekuhluzeni amasuntswana adlula kuyo.Ubungakanani bamaqhekeza ahluziweyo bubalulekile
DELTA P ( Uxinzelelo olwahlukileyo )imele ukuhla koxinzelelo kwimaski okanye ukuchasana nokuhamba komoya inmmh2o / cm2.Oku kugqiba ukuxhathisa ukuphefumla-iphezulu iDelta P, okukhona amandla okuphefumla kancinci, kodwa ngcono ukuhluza.
Ukutsha ukulinganisa ukusasazeka kwedangatye lemathiriyeli yemaski
UMTHOMBO :Ukucaciswa komgangatho we-ASTM wokusebenza kwezinto ezisetyenziswa kwiimaski zobuso bezonyango-f2100-11 umgangatho
* Njengoko kuchaziwe kwindlela yoVavanyo F 1862
“KHUSELEKA + ”Iimpawu zeMASKS YOBUSO
Utolo oluBlue: Iqhekeza lempumlo yealuminiyam eyongezelelekileyo kwaye kulula ukuyihlengahlengisa.
Isiqwenga sePlastiki phantsi kwesilevu ukuze silunge ngakumbi
Utolo olumfusa: Olu luyilo olutsha olu-4 lwepleyiti lulungele nayiphi na imilo yobuso kwaye lubonelela ngevolumu yokuphefumla ngakumbi
