Siv los ntsuas qhov suction kuj thiab exhalation tsis kam ntawm lub tshuab ua pa thiab lub tshuab ua pa nyob rau hauv cov xwm txheej tshwj xeeb. Nws muaj feem xyuam rau cov kev ntsuam xyuas thiab tshuaj xyuas cov qhov ncauj qhov ntswg zoo tib yam, lub ntsej muag plua plav, lub qhov ncauj qhov ntswg kho mob thiab cov npog ntsej muag uas ua los ntawm lub teb chaws kev tiv thaiv cov cuab yeej tshuaj ntsuam xyuas thiab cov tuam txhab daim npog ntsej muag.
Qauv:
TS EN 149-2001 A1-2009 Kev tiv thaiv ua pa ua pa - Kev xav tau rau lim - hom particle - pov thawj ib nrab-qhov ncauj qhov ntswg
GB 2626-2019 Respirators self-priming filter anti-particulate respirator 6.5 Suction resistance 6.6 expiratory resistance
GB / T 32610-2016 Kev qhia tshwj xeeb rau lub ntsej muag tiv thaiv txhua hnub 6.7 nqus pa 6.8 exhalation tsis kam
GB/T 19083-2010 Kev cai rau kev kho mob lub qhov ncauj qhov ntswg 5.4.3.2 Suction kuj thiab lwm yam qauv
European thiab American standard respirator resistance tester nta:
1, Siab simulation silicone taub hau pwm, simulation tiag tiag ntawm tus neeg hnav cov nyhuv.
2, Siv cov ntsuas ntsuas ntsuas, ruaj khov airflow.
3, Txheem lub taub hau pwm tuaj yeem hloov tau sai, yooj yim rau kev sim ntau yam qauv;
4, Xim kov npo zaub, zoo nkauj thiab dav. Daim ntawv qhia kev ua haujlwm hom yog yooj yim npaum li cov xov tooj ntse.
5, Cov khoom tseem ceeb tswj tau txais lub tuam txhab Italian 32 multi-function motherboard.
6, Lub sijhawm xeem tuaj yeem hloov kho raws li qhov yuav tsum tau ua.
7, Qhov kawg ntawm qhov kev xeem nrog lub suab nrov kawg.
8, Nruab nrog cov qauv tshwj xeeb tuav, yooj yim thiab yooj yim siv.
9, Qhov ntsuas tau nruab nrog qhov ntsuas ntsuas ntsuas ntsuas ntsuas.
10, Cov cuab yeej yog tsim los rau desktop, ruaj khov, tsis muaj suab nrov.
