Mwgwd FFP2

Mae masgiau FFP2 yn un o safonau masg Ewropeaidd EN149: 2001. Defnyddir masgiau FFP2 i adsorbio erosolau niweidiol, gan gynnwys llwch, mygdarth, defnynnau niwl, nwyon gwenwynig ac anweddau gwenwynig, trwy'r deunydd hidlo a'u rhwystro rhag cael eu blocio Anadlu.

Disgrifiad o''r Cynnyrch


Mwgwd FFP2


Mae masgiau categori FFP2 yn cyfeirio at fasgiau sy'n cwrdd â safonau Ewropeaidd (CEEN149: 2001). Rhennir safonau masgiau amddiffynnol Ewropeaidd yn dair lefel: FFP1, FFP2, FFP3. Mae'n wahanol i safon America yn yr ystyr ei fod yn defnyddio cyfradd llif canfod o 95 L / min ac yn defnyddio olew DOP i lwch.

Mwgwd FFP2s are one of the European mask standards EN149: 2001. Mwgwd FFP2s are defnyddiod to adsorb harmful aerosols, including dust, fume, mist droplets, toxic gases and toxic vapors, through the deunydd hidlo and block them from being blocked Inhale.

Mwgwd FFP1: isafswm effaith hidlo> 80%

Mwgwd FFP2: minimum filtering effect> 94%

Mwgwd FFP3: isafswm effaith hidlo> 97%

The deunydd hidlo of Mwgwd FFP2 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.

Offer profi


Mae'r categori masgiau FFP2, safonau Ewropeaidd ac Americanaidd, wedi'u nodi i'w profi gyda'r Profwyr Hidlo Awtomataidd Americanaidd TSI-8130. Mae'r safon Americanaidd yn defnyddio'r dull NaCl ar gyfer dosbarth N, y dull DOP ar gyfer dosbarth R, a'r dull DOP ar gyfer safonau Ewropeaidd.


Mae offeryn TSI-8130 yn defnyddio'r dull NaCl: gall yr offeryn gynhyrchu gronynnau halen yn awtomatig, diamedr y gronynnau ar gyfartaledd yw 0.2 μm (diamedr cyfartalog cyfanredol 0.26 μm, diamedr cyfartalog rhifyddeg 0.07 μm), mae'r sampl wedi'i gosod ar gyfradd llif benodol, yr offeryn yn argraffu Llif, gwrthiant, trawsyriant yn awtomatig.


Mae'r dull DOP yn defnyddio olew DOP ar gyfer llwch. Diamedr y gronynnau olew DOP yw 0.33 μm, a'r diamedr cyfartalog yw 0.20 μm.

defnyddio


1. Offer amddiffynnol personol a'i bwrpas yw atal neu leihau llwch yn yr awyr rhag mynd i mewn i'r organau anadlol dynol i amddiffyn bywyd;


2. Deunydd: Mae'r rhan fwyaf o'r masgiau gwrth-ronynnol wedi'u gwneud o ddwy haen o ffabrig heb ei wehyddu y tu mewn a'r tu allan, a lliain hidlo (brethyn wedi'i doddi) yn yr haen ganol;


3. Filtering principle: The filtering dust mainly depends on the middle filter cloth. Becadefnyddio 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 defnyddio 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. Gwrthrych amddiffyn: Rhennir y gwrthrych amddiffyn yn KP a KN. Gall y KP, fel y'i gelwir, amddiffyn gronynnau olewog ac nad ydynt yn olewog, a dim ond gronynnau nad ydynt yn olewog y gall KN eu hamddiffyn.


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 defnyddio.


FFP2 Mask


deunydd hidlo


Different Mwgwd FFP2s defnyddio different deunydd hidlos. The filtering effect is related to the particle size of the particles, and it is also affected by whether the particles contain oil. Mwgwd FFP2s 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" deunydd hidlos are more common, they are not suitable for oily particulates, such as oil mist, soot, asphalt smoke, coke oven smoke, and so on. The deunydd hidlo suitable for oily particles can also be defnyddiod 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 deunydd hidlo is composed of permanent static charged fibers. Respirable dust smaller than 5 μm will be attracted by static electricity and adsorbed on the deunydd hidlo when passing through this deunydd hidlo. It really plays a role in blocking dust.


Ail: Mae graddau'r agosrwydd rhwng y mwgwd a siâp wyneb yn well. Pan nad yw'r mwgwd yn agos at yr wyneb, bydd llwch yn yr awyr yn mynd i mewn i'r llwybr anadlol trwy'r bylchau o amgylch y mwgwd. Felly, dylai pobl ddewis mwgwd gwrth-ronynnau sy'n addas ar gyfer siâp eu hwyneb a gwisgo mwgwd gwrth-ronynnau yn iawn.


Trydydd: Gwisgwch yn gyffyrddus, gan gynnwys ymwrthedd anadlu bach, pwysau ysgafn, gwisgo hylan a chynnal a chadw cyfleus, fel gwisgo masgiau gwrth-ronynnau bwaog.

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

yn lân


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 defnyddiod 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 yn lân 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.


Mwgwd FFP2s are similar to N95 and KN95 masks and cannot be yn lâned. Becadefnyddio the wet will cadefnyddio the electrostatic discharge of the mask, it cannot absorb the dust with a diameter less than 5um.


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