FFP2-maske

FFP2-masker er en af ​​de europæiske maskestandarder EN149: 2001. FFP2-masker bruges til at adsorbere skadelige aerosoler, herunder støv, røg, tåldråber, giftige gasser og giftige dampe gennem filtermaterialet og forhindrer dem i at blive inhaleret.

Produkt beskrivelse


FFP2-maske


FFP2-kategorimasker refererer til masker, der opfylder europæiske (CEEN149: 2001) standarder. Standarderne for europæiske beskyttelsesmasker er opdelt i tre niveauer: FFP1, FFP2, FFP3. Det adskiller sig fra den amerikanske standard, idet den bruger en detektionsstrømningshastighed på 95 L / min og bruger DOP-olie til støv.

FFP2-maskes are one of the European mask standards EN149: 2001. FFP2-maskes are brugd to adsorb harmful aerosols, including dust, fume, mist droplets, toxic gases and toxic vapors, through the filtermateriale and block them from being blocked Inhale.

FFP1-maske: minimum filtreringseffekt> 80%

FFP2-maske: minimum filtering effect> 94%

FFP3-maske: minimum filtreringseffekt> 97%

The filtermateriale of FFP2-maske is mainly divided into four layers, that is, two layers of non-woven fabric + one layer of solvent spray cloth + one layer of needle punched cotton.

Testudstyr


FFP2-kategorien af ​​masker, både europæiske og amerikanske standarder, er specificeret til test med de amerikanske TSI-8130 automatiserede filtertestere. Den amerikanske standard bruger NaCl-metoden til klasse N, DOP-metoden til klasse R og DOP-metoden til europæiske standarder.


TSI-8130 instrument bruger NaCl-metoden: instrumentet kan automatisk frembringe saltpartikler, den gennemsnitlige partikeldiameter er 0,2 ¼¼ (aggregeret gennemsnitlig diameter 0,26 ¼¼, aritmetisk gennemsnitlig diameter 0,07 ¼¼), prøven indstilles til en bestemt strømningshastighed, instrumentet udskriver automatisk flow, modstand, transmission.


DOP-metoden bruger DOP-olie til støvning. Diameteren af ​​DOP-oliepartikler er 0,33 ¼¼m, og den gennemsnitlige diameter er 0,20 ¼¼m.

brug


1. Personligt beskyttelsesudstyr, hvis formål er at forhindre eller reducere støv i luften fra at komme ind i de menneskelige åndedrætsorganer for at beskytte livet;


2. Materiale: De fleste af de anti-partikelformige masker er lavet af to lag ikke-vævet stof inden og udenfor og en filterklud (smelteblæst klud) i mellemlaget;


3. Filtering principle: The filtering dust mainly depends on the middle filter cloth. Becabrug the melt-blown cloth has the characteristics of static electricity, it can adsorb positive particles. Since the fine dust is adsorbed on the original filter, and the original filter is electrostatically charged and cannot be washed, the self-priming filter type anti-particulate respirator needs to replace the original filter regularly.


4. Remarks: The requirements for the brug of anti-particulate masks are quite strict internationally. Anti-particulate masks belong to the first class in personal protective equipment, higher than earmuffs and protective glasses. The more authoritative testing certifications are European CE certification and American NIOSH certification, while Chinese standards are similar to American NIOSH


5. Beskyttelsesobjekt: Beskyttelsesobjektet er opdelt i KP og KN. Den såkaldte KP kan beskytte olieagtige og ikke-olieagtige partikler, og KN kan kun beskytte ikke-olieagtige partikler.


6, protection level: China's protection level is divided into KP100, KP95, KP90 and KN100, KN95, KN90. Among them, KP100 and KN100 have the highest filtration efficiency, and the national standard requires greater than 99.97%, so it is also the safest for brug.


FFP2 Mask


filtermateriale


Different FFP2-maskes brug different filtermateriales. The filtering effect is related to the particle size of the particles, and it is also affected by whether the particles contain oil. FFP2-maskes are usually classified according to filtration efficiency and classified as suitable for filtering oily particles. Oil-free particles such as dust, water-based mist, paint mist, oil-free smoke (welding smoke), microorganisms, etc. Although "non-oily particulate" filtermateriales are more common, they are not suitable for oily particulates, such as oil mist, soot, asphalt smoke, coke oven smoke, and so on. The filtermateriale suitable for oily particles can also be brugd for non-oily particles.

First: The dust blocking efficiency of the mask must be high. The dust blocking efficiency of a mask is based on its dust blocking efficiency against fine dust, especially respiratory dust below 5 μm. In general gauze masks, the principle of dust blocking is mechanical filtering, that is, when the dust hits the gauze, it will block some large particles of dust in the gauze after layer by layer of blocking. However, fine dust, especially dust smaller than 5 μm, passes through the mesh of gauze and enters the respiratory system. There are some anti-particulate masks on the market for sale.The filtermateriale is composed of permanent static charged fibers. Respirable dust smaller than 5 μm will be attracted by static electricity and adsorbed on the filtermateriale when passing through this filtermateriale. It really plays a role in blocking dust.


For det andet: Graden af ​​nærhed mellem masken og ansigtsformen er bedre. Når masken ikke er tæt på ansigtet, kommer støv i luften ind i luftvejene gennem hullerne omkring masken. Derfor bør folk vælge en anti-partikelmaske, der er egnet til deres ansigtsform og bære en anti-partikelmaske korrekt.


For det tredje: Bær behageligt, herunder lille åndedrætsbestandighed, let vægt, hygiejnisk slid og praktisk vedligeholdelse, f.eks. Iført buede anti-partikelmasker.

1. Disposable anti-particle mask: alias: "disposable FFP2 category mask" This anti-particle mask is suitable for short-term brug in polluted environments.


2. Half mask: alias: "FFP2 category mask" "dust mask" "dust mask" with exhalation valve design to reduce heat accumulation and make breathing easier, suitable for long-term brug in high temperature and high humidity environments. Non-toxic , Tasteless, non-allergic, non-irritating raw materials. High filtering efficiency and low resistance can adjust the nose clip to make the mask and the face tighter. The dust can not easily leak into the electrostatically treated filter layer. It can effectively filter and adsorb extremely fine harmful industrial dust and prevent silicosis. Ultrasonic welding, elastic bands of spandex filament materials are more effective for the wearer to protect the application: construction industry, agriculture and animal husbandry, food processing industry, cement factory, textile factory, cutting dust, heavy metal hazardous pollutants workplace.


3, full face mask: alias: dust full face mask, is brugd in special environments

ren


The outer layer of FFP2 type masks often accumulate a lot of dirt, bacteria and other dirt in the outside air, and the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be brugd alternately, otherwise the dirt contaminated by the outer layer will When it is in close contact with the face, it is sucked into the human body and becomes a source of infection. When not wearing the mask, it should be folded into a ren envelope, and the side that is close to the nose and mouth should be folded inward. Do not put it in your pocket or hang it around your neck.


FFP2-maskes are similar to N95 and KN95 masks and cannot be rened. Becabrug the wet will cabrug the electrostatic discharge of the mask, it cannot absorb the dust with a diameter less than 5um.


High-temperature steam disinfection is similar to rening. Water vapor also cabrugs electrostatic discharge, which cabrugs masks to fail.

If there is a UV lamp in the home, you can consider using a UV lamp to sterilize the surface of the mask to prevent accidental contact with the surface of the mask and cabrug pollution. It can also be sterilized at high temperature, but the mask is usually flammable. High temperature may also cabrug the mask to burn and cabrug safety hazards. It is not recommended to brug an oven and other facilities for high temperature disinfection.
