Maxay waji-xidhashadu uga hortagtaa fiditaanka fayraska?

Waa maxay nooca maaddadu?

Caadi ahaan waxaan niraahnaa maaskaro waxay ka samaysan yihiin maro aan tol lahayn.Dharka aan toliyaha ahayn waa maro aan tolmo lahayn, oo ka soo horjeeda maro tolmoon, kuwaas oo ka samaysan fiilooyinka toosan ama random.
Marka ay timaado waji-xidhka, alaabta ceeriin waa Polypropylene (PP).Maaskarada la tuuri karo guud ahaan waa polypropylene lakabyo badan.Magaca Ingiriisiga: Polypropylene, PP gaaban, waa midab la'aan, ur aan ur lahayn, aan sun ahayn, walax adag oo translucent ah, taas oo ah xarun polymer ka samaysan polymerization of propylene.Polypropylene waxaa si weyn loogu isticmaalaa soo saarista alaabta fiber-ka sida dharka iyo bustayaal, agabka caafimaadka, baabuurta, baaskiiladaha, alaabta dayactirka, tuubooyinka gaadiidka iyo weelasha kiimikada, iyo sidoo kale baakadaha cuntada iyo daawada.
Dharka aan toliyaha ahayn ee ay soo saartey walxaha gaarka ah ee polypropylene maro aan tol lahayn ayaa loo isticmaali karaa dharka qalliinka ee la tuuri karo, go'yaal, maaskaro, dabool, daboolka nuugista dareeraha iyo agabka kale ee caafimaadka iyo caafimaadka.

Maaskarada la og yahay inay ku leeyihiin saamaynta ilaalinta coronavirus-ka cusub inta badan waxaa ka mid ah maaskaro ilaalin ah oo la tuuri karo iyo maaskaro N95 ah.Shayga shaandhada ugu weyn ee labadan maaskaro waa mid aad u fiican, Dahaarka filter elektrostatic - dhar aan-dhogorta lahayn oo dhalaalaysa.Dharka dhalaalaysa ee la afuufay oo aan tolnayn ayaa inta badan laga sameeyaa polypropylene, waa nooc ka mid ah maro faybar ultrafine ah, oo qabsan karta boodhka.
Dhibcaha
oo ay ku jiraan fayraska oof-wareenka ee u dhow maro aan-dhogorta lahayn oo dhalaalaysa waxay noqon doontaa xayeysiis elektrostatic ah oo ku yaal dusha sare ee marada aan timaha lahayn, ma dhex mari karto, tani waa mabda'a tan. bakteeriyada go'doominta alaabta.Ka dib marka boodhka uu qabsado fiilada ultrafine electrostatic, aad bay u adag tahay in lagu kala saaro nadiifinta, iyo dhaqiddu waxay burburin doontaa awoodda ururinta boodhka korantada, marka maaskarada waxaa la isticmaali karaa hal mar oo kaliya.

Maaskarada ilaalinta la tuuri karo waxay guud ahaan ka samaysan yihiin saddex lakab oo dhar aan tol lahayn.Maaddadu waa maro aan toliyaha lahayn oo la kaxaystay + maro aan tol lahayn oo dhalaalaysa
Dhowr lakab oo waji-xidho ah ayaan lagu qeexin heerka qaranka GB/T 32610 ee waji-xidhka.Maaskarada caafimaadka, waa in ay jiraan ugu yaraan 3 lakab, oo loo yaqaan SMS (2 layers of S iyo 1 layer of M).
Tirada ugu badan ee lakabyada Shiinaha hadda waa 5 lakab, taas oo loo yaqaan SMMMS (2 layers of S iyo 3 layers of M).Halkan S waxay u taagan tahay lakabka Spunbond (Spunbond), dhexroorkiisu waa dhumuc yar, qiyaastii 20 microns (μm), doorka ugu weyn ee 2 lakab ee Spunbond waa in la taageero dhammaan qaab dhismeedka dharka aan tolmada lahayn, oo aan saameyn badan ku yeelan xannibaadda.Waxa ugu muhiimsan ee gudaha maaskarada waa lakabka xannibaadda ama lakabka Meltblown M (Meltblown).
Dhexroorka fiber-ka lakabka Meltblown waa mid aad u fiican, qiyaastii 2 microns (μm), kaas oo door muhiim ah ka ciyaara ka hortagga bakteeriyada iyo dhiigga inay galaan.
galay.Haddii lakabyada isku xiran ee S ay aad u badan yihiin, maaskaro waa adag tahay, lakabka buufinta M aad u badan, neeftu way adag tahay, markaa laga bilaabo fududaynta maaskaro neefsashada ilaa qiimaynta saamaynta maaskaro go'doomin ah, neefsasho badan adag, saamaynta xannibi waa ka fiican, laakiin, haddii M lakabka galay filimka, waa asal ahaan ha si xor ah u neefsan, fayraska waa la gooyaa, laakiin dadku ma neefsan karaan.N95 dhab ahaantii waa maaskaro 5-lakab ah oo laga sameeyay polypropylene nonwoven SMMMS taas oo shaandhaysa ilaa 95% walxaha yaryar.

Sidaa darteed, waxaan ogaanay in maaskaro si dhab ah u go'doomin kara fayraska ay tahay in laga sameeyo waxyaabo gaar ah, oo aan dhammaan agabku ku habboonayn maaskaro.
Sida ugu dambaysta, waxaan si dhab ah u rajaynayna in qof walba uu ilaalin karo naftaada iyo caafimaadkaaga.
