According to the minimum filtration efficiency of the filter material, under the specified conditions, the mask body can filter out particulate matter. The larger the value, the higher the protection level and the greater the respiratory resistance. Masks can be divided into three levels, the lowest filtration efficiency of 95% is 95%, the lowest filtration efficiency of 99 is 99%, and the lowest filtration efficiency of 100 is 99.97%.
Li gorî senifandina standard, N ya ku li ser maskê hatî nîşankirin, standarda Amerîkî temsîl dike, FFP standarda Ewropî ye, û KN standarda Çînî ye.
FFP European standard masks are certified by the European Standards Committee for respiratory protective equipment. The standard is to divide the particulate protection filter material into solid particle protection and liquid particle protection, which are tested and classified by NaCL (sodium chloride) and DOP (paraffin oil) aerosols. The role is to absorb harmful aerosols, including dust, smoke, mist, poisonous gas and poisonous vapor, etc. through the filter material, blocking them from being inhaled by people. Qualified solid particle protection filter materials are divided into three levels: P1 (FFP1), P2 (FFP2), and P3 (FFP3) according to the tested particle penetration rate. The minimum filtering effect of FFP1 is ≥80%, and the minimum filtering effect of FFP2 is ≥94%. , FFP3 minimum filtering effect ≥97%.
American standard masks are graded by the National Institute of Occupational Safety and Health (NIOSH) for their filter material and filtration efficiency. The American NIOSH 42CFR-84 standard has the highest degree of recognition in the world. According to the filter material of the middle layer of the mask, there are three types:
N stands for Not resistant to oil, which can protect against non-oily suspended particles. For example, the oily fume produced by cooking is oily particles, while the droplets produced by people talking or coughing are not oily. Generally, non-oily particulate matter refers to coal dust, cement dust, acid mist, microorganisms, etc. In the current haze pollution, most of the suspended particles are non-oily. Oily particulate matter refers to oil fume, oil mist, asphalt fume, etc.
R stands for Resistant to oil, which can protect non-oily and oily suspended particles, but when used for oily particles, the use time should not exceed 8 hours.
P stands for Oil Proof, which can protect against non-oily and oily suspended particles. Compared with the R series, the P series can be used for a relatively long time, depending on the manufacturer's label.
In this way, it is easy to understand what an N95 mask is. The N95 mask is tested with 0.3 micron sodium chloride particles, and the barrier rate must be above 95%. When the wearer’s face is tested for tightness, it is ensured that air can enter and exit through the mask when it is close to the edge of the face. N95 certification number is issued for this test.
KN is a Chinese standard, and its detection method is the same as that of the United States. According to my country's GB2626-2006 standard, masks are divided into KN and KP categories. KN means masks are suitable for filtering non-oily particles, and KP means masks are suitable for filtering oily particles. And non-oily particles. The number after the letter represents the protection level of the mask, the larger the number.
Pêdivî ye ku asta parastinê di navbera sê maskeyên standard ên cûda de çawa were veguheztin? Diyar e, EU FFP dikare di heman demê de perçeyên ne-rûn û rûn bişkîne, lê N û KN li Dewletên Yekbûyî û Çînê tenê dikare bi bandor bandorên ne-rûn parzûn bike. Ji ber vê yekê, formula bandora wan a parastinê bi kêmasî ye: FFP3> FFP2 = N95 = KN95> KN90
1. Maskên bijîjkî yên asayî têne bikar anîn ku splashesên ku ji dev û devê poz têne derxistin, bloke bikin, û dikarin ji bo lênihêrîna paqijiya yek-carî li derdorên bijîjkî yên asayî yên bi parastina asta herî nizm werin bikar anîn. Ew ji bo çalakiyên lênihêrîna tenduristiyê ya gitî, wekî paqijî, amadekirina şilavê, paqijkirina yekîneyên razanê, û hwd., An astengî an parastina kerikên ji bilî mîkroorganîzmayên patojenîk ên mîna polen e.
Rola herî bibandor a 95 maskan pêşîgirtin û venêrana belavbûna nexweşiyên nefesê yên giran e, wekî SARS an înfluensza û derketina korona virusa nû. Hûn dikarin maskeyên ku bi standardên KN95, N95, FFP2 û jor hatine nîşankirin hilbijêrin.
2. Studies have shown that within the pre-specified range, surgical masks are no worse than KN95/N95 masks in preventing influenza. Zhong Nanshan, the leader of the high-level expert group of the National Health Commission to fight SARS, also said, "In fact, it is not necessary to wear N95 masks. General masks can block most of the virus-laden droplets from entering the respiratory tract and prevent the new coronavirus. , It’s useful to wear a mask.” So if you can’t buy an N95 mask, you can choose a general surgical mask.
5. Maskên KN95 / N95 li du celeb têne dabeş kirin, yek respirasyonek biyolojîkî ye û ya din jî hilmijê tozê ye.
Their protection levels are the same, but the implementation standards are different. The standard for bio-protective masks (medical KN95) is GB19083-2010 "Technical Requirements for Medical Protective Masks", which is used in the medical and health industries, such as epidemic prevention stations, hospitals, and disease control centers. The dust respirator (KN95) implements the standard GB2626-2006 "Respiratory Protective Equipment Self-priming Filtered Anti-Particulate Respirator", which is used in industries such as coal mining, petroleum processing, mining and other industrial and mining enterprises.
If you are using it in an ordinary environment, you can choose the KN95 (or N95 if it is the American standard) mask of GB2626-2006. If it is a medical institution or contact with infected people, it is necessary to prevent flying caused by the patient's body fluid or blood splash. If you are infected with foam, you must use KN95 masks that implement the GB19083-2010 standard.
Bi kurtahî, li hawîrdorek nisbeten bi rîsk, maskeyên ku dikarin bi bandor pêşî li enfeksiyonên nefesê bigirin, maskeyên parastinê yên tibî û maskeyên nişdarî yên tibî ne. Maskên parastinê yên bijîjkî, ku wekî KN95 bijîjkî jî tê zanîn, ji bo ku ji hêla karmendên bijîşkî ve li klînîkên tayê, wargehên tecrîdê, û nexweşên piştrastkirî gava têne veguheztin bikar bînin. Maskên nişdarî yên bijîşkî ji bo lixwekirina bûyerên gumanbar guncan in. Ew ji hêla karmendên rêwîtiyên giştî û rêwî, texsî, ajokar, karkirên paqijiyê û karmendên karûbarê ve li cihên gelemperî têne avêtin.
Tedbîrên ji bo karanîna maskeyan ve girê bidin:
1. Dema ku ji bo parastina perçeyên rûn tê bikar anîn, dema karanîna komî ya pola R di yek carî de 8 demjimêran derbas nake; dema karanîna komî ya pola P 40 demjimêran derbas nake, an dema karanîna komker digihîje 30 rojan ji despêkê, kîjan zûtir were.
2. Maskên parastinê bi avê nayên şûştin, ji ber ku şûştina bi avê dê materyalê parzûnê û avahiya maskeyê hilweşîne; heke ew ne qirêjî û zirar be, û hewcedariyên paqijiyê bicîh bîne, ew dikare ji nû ve were bikar anîn.
3. N95 mask ne marqeyek marqeyek hilberê an marqeyek e. N95 hewcehiya asta herî nizm a NIOSH (Enstîtuya Neteweyî ya Ewlehî û Tenduristiya Karker) ji bo asta karîgeriya parzûnê ya respiratorên dij-partîkul ên kar ên Amerîkî. Karîgeriya parzûnkirina madeyên kumikî (wekî xwelî, mija boyaxê, mija asîdê, mîkroorganîzmayên hwd.) Bi kêmasî% 95 e.
4. Çiqas bandorkirina parzûnê ya maskeyê, ew qas berxwedana nefesê jî mezin dibe. Ji ber vê yekê, demek dirêj kişandina maskeyên N95 ji bo laş ne baş e, ji ber vê yekê wan demek dirêj li xwe nekin.
5. Di derbarê frekansa guheztina maskê de, aniha encamek zelal tune, û welatê min hîna rêziknameyên têkildar li ser dema karanîna maskeyan çênekiriye. Hin lêkolîneran li ser karîgeriya parastinê û dema lêdana maskeyên parastinê yên bijîjkî KN95 lêkolînên têkildar kirine. Encam nîşan didin ku maskeyên KN95 2 rojan têne hildan, bandora parzûnê ji% 95 di jor de dimîne, berxwedana nefesê hindik diguhere, û bandorkirina parzûnê piştî ku 3 rojan li xwe dike, li 94.7% kêm dibe.
