Masko de kategorio FFP2


Masko de kategorio FFP2s refer to masks that meet European (CEEN149: 2001) standards. The standards of European protective masks are divided into three levels: FFP1, FFP2, FFP3. It is different from the American standard in that it uzis a detection flow rate of 95 L / min and uzis DOP oil to dust.

Provanta ekipaĵo


La kategorio de maskoj FFP2, ambaŭ eŭropaj kaj usonaj normoj, estas specifitaj por provoj kun la usona TSI-8130 Automated Filter Testers. La usona normo uzas la NaCl-metodon por klaso N, la DOP-metodon por klaso R, kaj la DOP-metodon por eŭropaj normoj.
TSI-8130-instrumento uzas la NaCl-metodon: la instrumento povas aŭtomate generi salajn partiklojn, la meza partikla diametro estas 0,2 μm (agregata averaĝa diametro 0,26 μm, aritmetika averaĝa diametro 0,07 μm), la specimeno estas agordita je certa fluo, la instrumento aŭtomate presas Fluon, reziston, transmitancon.
La DOP-metodo uzas DOP-oleon por polvo. La diametro de la DOP-oleo-eroj estas 0,33 μm, kaj la meza diametro estas 0,20 μm.

uzi


1. Persona protekta ekipaĵo kies celo estas malebligi aŭ redukti polvon en la aero eniri la homajn spirajn organojn por protekti vivon;
2. Materialo: Plej multaj kontraŭ-partiklaj maskoj estas faritaj el du tavoloj de ne-teksita teksaĵo interne kaj ekstere, kaj filtra tuko (fandita blovita tuko) en la meza tavolo;
3. Filtering principle: The filtering dust mainly depends on the middle filter cloth. Becauzi 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 uzi 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. Protekta objekto: La protekta objekto estas dividita en KP kaj KN. La tiel nomata KP povas protekti olajn kaj ne oleajn partiklojn, kaj KN nur povas protekti neeleajn erojn.
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 uzi.

filtri materialon


Different FFP2 masks uzi different filtri materialons. The filtering effect is related to the particle size of the particles, and it is also affected by whether the particles contain oil. FFP2 masks 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" filtri materialons are more common, they are not suitable for oily particulates, such as oil mist, soot, asphalt smoke, coke oven smoke, and so on. The filtri materialon suitable for oily particles can also be uzid for non-oily particles.

elektu


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 filtri materialon is composed of permanent static charged fibers. Respirable dust smaller than 5 μm will be attracted by static electricity and adsorbed on the filtri materialon when passing through this filtri materialon. It really plays a role in blocking dust.
Due: la grado de proksimeco inter la masko kaj vizaĝa formo estas pli bona. Kiam la masko ne estas proksima al la vizaĝo, polvo en la aero eniros la spira vojo tra la interspacoj ĉirkaŭ la masko. Tial homoj devas elekti kontraŭ-partiklan maskon taŭgan por sia vizaĝa formo kaj porti kontraŭ-partiklan maskon ĝuste.
Tria: Portu komforte, inkluzive de malalta spira rezisto, malpeza pezo, higiena eluziĝo, kaj facila bontenado, kiel ekzemple portado de arĉaj anti-partiklaj maskoj.

1. Disposable anti-particle mask: alias: "disposable Masko de kategorio FFP2" This anti-particle mask is suitable for short-term uzi in polluted environments.
2. Half mask: alias: "Masko de kategorio FFP2" "dust mask" "dust mask" with exhalation valve design to reduce heat accumulation and make breathing easier, suitable for long-term uzi 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 uzid in special environments

pura


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 uzid 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 pura 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 masks are similar to N95 and KN95 masks and cannot be puraed. Becauzi the wet will cauzi the electrostatic discharge of the mask, it cannot absorb the dust with a diameter less than 5um.


High-temperature steam disinfection is similar to puraing. Water vapor also cauzis electrostatic discharge, which cauzis 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 cauzi pollution. It can also be sterilized at high temperature, but the mask is usually flammable. High temperature may also cauzi the mask to burn and cauzi safety hazards. It is not recommended to uzi an oven and other facilities for high temperature disinfection.
