Chigoba chosefa theka (8228V-2 FFP2)

Ubwino wa masks okhala ndi ma valve opumira ndi chiyani?
Valavu yopumira ya chigoba ndi yoyenera kumalo otentha kwambiri. Zidzakhala zopumira kwambiri potulutsa mpweya, ndipo valavu yopumira mpweya imatseka yokha, zomwe sizingakhudze kugwiritsa ntchito konse.

Poyerekeza ndi masks amaso wamba, masks okhala ndi mavavu opumira ndi oyenera kugwiritsidwa ntchito movutikira komanso amathandizira kupuma kwa anthu. M'malo ogwirira ntchito achinyezi komanso otentha omwe mulibe mpweya wabwino kapena kuchuluka kwa ntchito, kugwiritsa ntchito chigoba chokhala ndi valavu yopumira kungakuthandizeni kukhala omasuka mukatulutsa mpweya.

Mfundo yogwira ntchito ya valavu yopumira ndi yakuti kupanikizika kwabwino kwa mpweya wotulutsidwa kumawombera mbale ya valve yotseguka pamene ikutulutsa mpweya, kuti muthe mwamsanga kuchotsa mpweya wonyansa m'thupi ndi kuchepetsa kutentha ndi kutentha pamene mukugwiritsa ntchito chigoba. Kupanikizika koyipa pakukoka kumangotseka valavu kuti musapume zowononga kuchokera kumadera akunja.

Kumaso chigoba ndi acupuncture thonje
Thonje la Acupuncture limatchedwanso singano nkhonya kupanga thonje mu makampani otaya fumbi kumaso. Thonje wokhomeredwa ndi singano wa chigoba ndi mtundu wa zinthu za chigoba zopangidwa ndi kufunikira. Imatchedwanso chigoba chotsimikizira fumbi pambuyo pophatikizidwa ndi maski processing. Thonje wokhomeredwa ndi singano wa chigoba ndi mtundu wa zinthu zosefera, zomwe zimapangidwa ndi ulusi wa poliyesitala pokhomerera singano. Mukudutsa muzosefera izi, fumbi lopumira lidzalowetsedwa pakati pa ulusi, womwe umathandizira kupewa fumbi.

Masks a thonje okhomedwa ndi singano ndi oyenera migodi, zomangamanga, zoyambira, kugaya ndi mankhwala, ulimi ndi ulimi, nkhalango ndi kuweta nyama, uinjiniya wapansi panthaka, ntchito ya aluminiyamu, zida zamagetsi ndi zamagetsi, zida ndi zida, mafakitale opanga chakudya, chomera cha simenti, chomera cha nsalu, zida ndi zida za Hardware, kugaya zitsulo, kupukuta, kudula, kuphwanya uinjiniya. Amatha kuteteza zitsulo zosakhala ndi chitsulo, zitsulo zolemera ndi zowononga zina, ndikutchinga magalasi CHIKWANGWANI Asbestosi ndi zinthu zina zovulaza.

Kusiyanitsa kwapakatikati ndi imodzi mwa njira zoyesera zowunikira chigoba.

Njira yoyesera - Kusiyana kwapakatikati
Kusiyana kwa kuthamanga, kapena kutsika kwamphamvu, kumawonetsa momwe kulili kosavuta kupuma kudzera muzosefera. Kusiyanitsa kwapanikiziko nthawi zambiri kumatsimikiziridwa poyesa kuthamanga kwa mpweya mbali zonse za zosefera pomwe mpweya umayenda pa liwiro lodziwika kudzera muzosefera. Kusiyanitsa kwapanikizi ndiko kusiyana pakati pa kukakamiza kwa mpweya kuwiri. Kusiyana kwapang'onopang'ono kumatanthauza kuti mpweya umadutsa mosavuta muzosefera, zomwe zimapangitsa kuti zikhale zosavuta kupuma. Pakuwunika koyeserera, kuchepetsa kuthamanga kwa mpweya kumachepetsa kusiyanasiyana kwa kuthamanga ndipo kukulitsa makulidwe a zinthu zosefera kumawonjezera kusiyana kwa kuthamanga.

Kusiyana kwapanikiziko kumanenedwa m'mayunitsi a pascal (Pa) (1.0 Pa = 0.102 mmH2O). Miyezo ina yosiyanitsa ya masks opangira opaleshoni imagwiritsa ntchito Pa/cm2, yomwe ilibe tanthauzo lenileni. Mayeserowa, komabe, amatchulanso malo a chigoba choyesedwa, kotero kuti mfundozo zachulukitsidwa ndi malo omwe amayesedwa kuti apeze gawo lofunikira pathupi, Pa.

EN 149:2001
Ku Europe, zopumira zosefera za nkhope ziyenera kukhala ndi mawonekedwe omwe akuwonetsedwa ndi muyezo wa EN 149:2001 (+ A1: 2009), womwe umalamula kuti masks awa, mwa zina, azikhala ndi mawonekedwe apadera a kupuma, kutulutsa mkati, kuyaka, kudzikundikira kwa CO2, ndi zina. masks ayesedwe onse ndi aerosol ya tinthu ta NaCl yokhala ndi m'mimba mwake yogawa pakati pa 0.06 ndi 0.10 μm komanso ndi aerosol ya tinthu tating'ono ta mafuta a parafini okhala ndi m'mimba mwake wapakati pakati pa 0.29 ndi 0.45 μm; palibe kuyesa kwa bakiteriya kusefera moyenera komwe kumafunsidwa. Kutengera mphamvu yawo yosefera, zopumira za sefa za nkhope zimayikidwa mumtundu wa FFP1 (sefa mphamvu ya NaCl aerosol ndi mafuta a parafini ofanana ndi 80%), FFP2 (sefa mphamvu ya NaCl aerosol ndi mafuta a parafini ofanana ndi 94%) ndi FFP3 (sefa mphamvu ya NaCl aerosol ndi mafuta a parafini ofanana ndi 99%).
