Txoj haujlwm thiab kev tiv thaiv ntawm KN95 daim npog ntsej muag |KENJOY

Dab tsi yog lub luag haujlwm ntawmKN95 Mask?Dab tsi yog qhov pov tseg Kn95?Yam kev tiv thaiv zoo li cas tuaj yeem ua si, tom ntejkn95 daim npog qhov ncauj lag luam wholesalelos muab lus piav qhia yooj yim rau koj.

Lub luag haujlwm ntawm kn95

Kev lim dej ua haujlwm ntawm cov khoom nrog aerodynamic txoj kab uas hla ≥0.3m tuaj yeem ncav cuag ntau dua 95% thaum hnav KN95 daim npog ntsej muag.Lub aerodynamic txoj kab uas hla ntawm cov kab mob hauv huab cua thiab cov kab mob fungal feem ntau txawv ntawm 0.7-10m, uas tseem nyob hauv nws qhov kev tiv thaiv ntau yam.

Yog li, lub tshuab ua pa tuaj yeem siv rau kev tiv thaiv kev ua pa ntawm qee yam hais, xws li cov plua plav uas tsim los ntawm kev sib tsoo, ntxuav thiab ua cov zaub mov, hmoov nplej thiab lwm yam khoom siv, nrog rau cov kua lossis cov roj uas tsis muaj roj uas tsim los ntawm kev txau uas tsis tsim. teeb meem volatile gases.

Kev lim dej kom zoo thiab ua kom huv ntawm cov ntxhiab tsw ntxhiab (tshwj tsis yog cov pa roj carbon monoxide), pab txo qis qhov kis tau rau qee qhov nqus tau cov kab mob microbial (xws li pwm, bacillus anthracis, tuberculosis, thiab lwm yam), tab sis tsis tshem tawm txoj kev pheej hmoo ntawm kev sib cuag, mob lossis tuag.

KN95 qib yog ib qib uas tau teev tseg hauv Suav tus qauv GB2626-2006.

Dab tsi yog qhov pov tseg KN95 daim npog qhov ncauj

"Pisposable" yog lub ntsiab lus ntawm cov khoom lag luam hauv lub teb chaws tus qauv, uas txhais tau hais tias cov khoom tsis tuaj yeem raug ntxuav thiab tag nrho cov khoom yuav tsum muab pov tseg tam sim ntawd thaum twg cov khoom ua tsis tiav.Respirators yog reusable thiab tsis tas yuav muab pov tseg ib zaug siv.

Cov qhov ncauj qhov ntswg pov tseg uas tuaj yeem muab pov tseg txhua qhov chaw, txhua lub sijhawm, raws li lub npe qhia

Txij li qhov tsim qauv tseem ceeb ntawm lub tshuab ua pa yog qhov chaw ua haujlwm, nws feem ntau tau teev tseg tias lub tshuab ua pa tuaj yeem hloov tau tom qab ib qho kev ua haujlwm, feem ntau vim tias lub tshuab ua pa tsis tuaj yeem ntxuav thiab cov neeg ua haujlwm yuav tsum tsis txhob siv lub ntsej muag tsis huv.

Txawm li cas los xij, lawv tuaj yeem rov qab siv tau yog tias lawv tau siv rau lub sijhawm luv luv, tsis muaj teeb meem kev noj qab haus huv, thiab lawv tsis ua haujlwm tsis zoo (xws li deformed lossis puas), lossis qhov nce hauv kev ua pa siab dhau lawm.

Txoj cai tiv thaiv ntawm FFP2 daim npog qhov ncauj

Cov khoom siv los lim cov teeb meem muaj cov ntxhia fiber ntau, ntuj fiber ntau lossis hluavtaws fiber ntau, lim cov khoom siv fiber ntau tau muab faib ua tsib hom kev lim dej ntawm cov khoom hauv huab cua, lawv tuaj yeem ua lub luag haujlwm dav.

Sedimentation: cov khoom loj loj hauv cov cua ntws yog cuam tshuam los ntawm lub ntiajteb txawj nqus sedimentation rau cov khoom lim, sib cais los ntawm airflow;

Inertia cuam tshuam: thaum cov khoom nyob rau hauv airflow bypass block nyob rau hauv pem hauv ntej ntawm lub lim cov ntaub ntawv fiber ntau, qhov zoo dua ntawm cov khoom yuav deviate los ntawm cov kev taw qhia ntawm lub airflow los ntawm inertia, ntaus lub lim cov ntaub ntawv fiber ntau lim;

Kev cuam tshuam: cov khoom nyob rau hauv cov huab cua yog ze tshaj rau cov streamline ntawm cov khoom lim, vim hais tias lub vojvoog ntawm cov khoom yog ntau dua qhov kev ncua deb ntawm cov streamline thiab cov khoom lim yog "scraped" thiab cuam tshuam los ntawm cov khoom lim;

Cov nyhuv diffusion: cuam tshuam los ntawm thermal txav ntawm huab cua molecules, tsis tshua muaj me me los ntawm kev cuam tshuam ntawm huab cua molecules, tas li hloov cov kev taw qhia ntawm kev txav, Brownian motion, random kev sib cuag nrog cov lim fiber ntau yog lim;

Cov nyhuv electrostatic: yog tias cov khoom siv lim fiber ntau nrog cov hluav taws xob tsis muaj zog, tsis hais seb cov khoom hauv cov cua ntws nws tus kheej nrog cov hluav taws xob zoo li cas, thaum lawv nyob ze rau cov khoom siv lim fiber ntau yooj yim rau kev nyiam los ntawm hluav taws xob zoo li qub thiab lim, cov nyhuv electrostatic tuaj yeem ua tau. pab lim cov ntaub ntawv txhim kho cov lim dej kom tsis txhob ua kom cov cua ntws tawm

Cov saum toj no yog lub luag hauj lwm ntawm KN95 daim npog qhov ncauj thiab kev tiv thaiv lub hauv paus ntsiab lus ntawm cov kev taw qhia, xav paub ntau ntxiv txog FFP2 daim npog qhov ncauj, txais tos hu rau peb.daim npog qhov ncauj lag luam wholesale.
