Qhov teeb meem tseem ceeb yog qhov kev ua kom pom tseeb tsis yog raws li tus qauv, kev tiv thaiv kev thaiv cov tee dej yog txo, thiab cov kab mob, kab mob thiab lwm yam aerosols raug lim. Lub peev xwm ntawm lub tuam txhab raug cuam tshuam, thiab tej zaum yuav muaj qee yam kev nyab xeeb. Tsis tas li ntawd, ntau lub qhov ncauj qhov ntswg uas muaj teeb meem uas tau nkag mus rau hauv kev lag luam tau muab tso rau hauv kev siv thiab tsis tuaj yeem rov qab thiab hloov pauv. Ntxiv rau qhov tseem ceeb zais kev phom sij rau cov neeg siv' Kev nyab xeeb ua pa tshwm sim los ntawm cov qhov ncauj qhov ntswg tsis zoo, qhov nyuaj ntawm kev siv cov txheej txheem rov qab los ntawm qhov ncauj qhov ntswg kuj tseem muaj kev pheej hmoo ntxiv. Hauv kev ua haujlwm tiag tiag, nws tsis yooj yim rau rov nco qab cov teeb meem qhov ncauj qhov ntswg, thiab ntau ntawm lawv tseem tsis tuaj yeem rov qab.
Cov kws tshaj lij tau taw qhia tias ntau hom npog ntsej muag muaj qhov sib txawv rau kev pom kev ua haujlwm zoo. Particle filtration efficiency thiab bacterial filtration efficiency yog ob lub ntsiab qhia ntawm seb kuv lub teb chaws' lub qhov ncauj qhov ntswg puas tsim nyog los tsis. Raws li" Txhua Hnub Kev Tiv Thaiv Lub Ncauj Lus Qhia Txog Cov Lus Qhia (GB/T32610-2016)", qhov pom kev ua haujlwm zoo (ntsev nruab nrab) ntawm daim npog tiv thaiv yuav tsum tsis pub tsawg dua 90%. Rau cov qhov ncauj qhov ntswg kho mob uas siv ntau tshaj plaws, kuv lub teb chaws' s" Disposable Medical Masks (YY/T0969-2013)" xav kom cov kab mob filtration efficiency yuav tsum tsis txhob tsawg tshaj li 95%.

Cov tshuab tsim khoom thiab kev tswj xyuas zoo ntawm qee cov tuam txhab npog ntsej muag tsis zoo txaus. Vim yog kev lag luam kub, tus naj npawb ntawm cov tuam txhab npog ntsej muag tau nce siab xyoo tas los. Thaum qee lub tuam txhab tshiab uas tsis muaj kev paub ntau lawm yuav yaj cov ntaub qhwv, lawv tsuas yog siv cov huab hwm coj hauv ib cheeb tsam (feem ntau hu ua gram hnyav) raws li qhov kev xaiv qhov ntsuas, thiab feem ntau tsis quav ntsej qhov ntsuas ntawm cov tshuab ziab khaub ncaws kom pom kev ua haujlwm zoo. .
Xyoo 2020, Jiangsu Fiber Inspection Bureau, ua ke nrog ntau chav nyob, tau tshaj tawm ib pawg txheej txheem rau polypropylene meltblown nonwovens rau lub ntsej muag. Lub koom haum Guangdong Nonwovens Association tau koom ua ke tsim thiab tso tawm ntau cov ntaub nplaum uas tsis muaj ntaub qhwv rau lub qhov ncauj qhov ntswg. Pab pawg qauv. Cov kws tshaj lij hauv kev lag luam hais tias, xa mus rau pawg qauv ntawm Jiangsu thiab Guangdong, lub teb chaws tus qauv rau yaj tshuab ziab khaub ncaws yuav tsum tau tsim kom sai li sai tau, thiab cov khoom faib, pom kev ua haujlwm zoo, qhov cua tsis kam, cov qauv zoo, kev txheeb xyuas cov khoom, cov txheej txheem kuaj, thiab lwm yam ntawm cov ntaub nplaum yaj rau lub qhov ncauj qhov ntswg yuav tsum tau qhia meej. Cov qauv kev tshawb fawb thiab cov qauv meej qhia kev txhim kho zoo ntawm cov tuam txhab npog ntsej muag.
