ffp2 imaski vs pm2.5|KENJOY

Kungakhathaliseki ukuthi sibhekene nobhubhane lomhlaba wonke noma imililo yequbula eyinhlekelele edala intuthu eqopha umlando nokungcoliswa komoya, kuncane okwaziwayo ngomehluko phakathiffp2 imaskikanye namamaski e-particulate filter pm2.5.Kokubili imaski ye-FFP2 kanye nemaski ezinhlayiyana ezinezihlungi ze-pm2.5 kunikeza isivikelo esihle kakhulu ezinhlayiyeni ezincane ezisemoyeni.Kokubili imaski ye-ffp2 ne-PM2.5 ilungele ukulwa nezinhlayiya ezinkulu ezinokuphatheka kabi okuncane.Kufanele isetshenziswe nini enye yalezi, ikakhulukazi lapho umhlinzeki wezempilo edinga umshini wokuphefumula wezokwelapha?

I-FFP2 imaski

Amamaski e-FFP2 awusizo ezibhedlela, emahhovisi odokotela nakwezinye izindawo lapho amagciwane atholakala emoyeni avamile khona.Amamaski e-Ffp2 alungele ukuvimbela uketshezi lomzimba oluqukethe amagciwane namagciwane ukuthi lungaphumi emzimbeni wakho, kodwa hhayi ngempela ukuthi lungene emzimbeni wakho.Ngokuvamile, imaski ye-ffp2 iklanyelwe ukuvikela abantu abaseduze kwakho ngokunciphisa izinhlayiya eziphuma emoyeni eziphuma emlonyeni nasemakhaleni akho, okuhlanganisa nama-virion ashayisana noketshezi lomzimba wakho.

Ngenxa yokuthi izifihla-buso ze-ffp2 zenzelwe ukuvimba amaconsi amanzi, ngokuvamile ziyaxega futhi zingashiya igebe phakathi konqenqema lwemaski nesikhumba sakho.Yize amaconsi asinda kakhulu mancane amathuba okuthi adlulele onqenqemeni lwemaski, lezi zikhala zenza imaski ingasebenzi kahle ekuvimbeleni ukuhlasela kwezinhlayiya ezincane, ezilula ezingangena phakathi kwezikhala eziningi phakathi kwemaski ye-ffp2 nobuso bakho.

Imaski yezinhlayiyana

Ayaziwa nangokuthi amamaski e-PM2.5, alingana kangcono kunamaski we-ffp2 futhi ngokuvamile angasetshenziswa kabusha.Nokho, ngokungafani namamaski e-ffp2, izifihla-buso ze-"PM 2.5" zenzelwe ukuvikela wena nabanye, ngakho zivame ukungena kangcono, zibe nemibimbi embalwa, futhi zingaqukatha (ahlungiwe) amavalvu okuphefumula.Lezi zimaski zivame ukupakishwa ngezihlungi ezilahlwayo ezingu-2.5.Ngokuya "ngebanga" lalezi zimaski, zingaklanywa ukuhlunga u-65% kuya ku-90% wezinhlayiya ezinhle ze-aerosol, ezingaphansi kancane kuphela kumaski we-N95, kodwa ngomfutho ophansi wokumunca.

Izinhlobo ezahlukene zamamaski e-FFP2 zisebenzisa izihlungi ezihlukile.Ngakolunye uhlangothi, umphumela wokuhlunga uhlobene nosayizi wezinhlayiyana, kodwa futhi uthintekile ukuthi izinhlayiya ziqukethe amafutha noma cha.Amamaski e-FFP2 ngokuvamile ahlukaniswa ngokuvumelana nokusebenza kahle kokuhlunga futhi ngokuya ngokuthi akulungele yini ukuhlunga izinhlayiya ezinamafutha.Izinhlayiya ezingenawo uwoyela ezifana nothuli, inkungu esekelwe emanzini, inkungu kapende, intuthu engenawo uwoyela (intuthu yokushisela), ama-microorganisms, njll. Nakuba izinto zokuhlunga "zezinhlayiya ezingezona amafutha" zivamile, azifanele izinhlayiya ezinamafutha. , njengenkungu yamafutha, i-oil fume, i-asphalt fume, intuthu ye-coke oven nokunye.Izinto zokuhlunga ezifanele izinhlayiya ezinamafutha zingasetshenziselwa izinhlayiya ezingenawo amafutha.

Imaski ye-ffp2 ilungele ini

1. Imikhiqizo yokuzivikela yomuntu siqu eyenzelwe ukuvimbela noma ukunciphisa ukungena kothuli oluvela emoyeni lungene ezithweni zokuphefumula zomzimba womuntu ukuze kuvikelwe ukuphepha kokuphila.

2. Izinto zokwakha: amamaski alwa nezinhlayiya ngokuvamile enziwa ngezingqimba zangaphakathi nezingaphandle zendwangu engalukiwe kanye nongqimba oluphakathi lwendwangu yokuhlunga (indwangu encibilikisiwe).

3. Isimiso sokuhlunga: ukuhlunga uthuli olucolile ikakhulukazi kuncike endwangu yokuhlunga phakathi.Ngenxa yokuthi indwangu encibilikayo inezici zayo zikagesi omile, ingakwazi ukumunca izinhlayiya ezincane ngenkuthalo.Ngenxa yokuthi uthuli lukhangisiwe kusihlungi sangempela, futhi isihlungi sangempela asikwazi ukugezwa ngogesi omile, isihlungi esizibambayo esilwa nezinhlayiya sidinga ukushintshwa njalo.

4. Ukuphawula: ukusetshenziswa kwezifihla-buso kuqinile kakhulu emhlabeni.Amamaski alwa nezinhlayiya angawezinga lokuqala emishinini yokuzivikela yomuntu siqu, ephakeme kunama-earmuffs nezingilazi zokuzivikela.Izitifiketi zokuhlola ezigunyazwe kakhulu isitifiketi se-CE e-Europe kanye nesitifiketi se-NIOSH e-United States, kuyilapho izinga lase-China lifana nele-NIOSH e-United States.

5. Izinto ezivikelayo: izinto ezivikelayo yi-KP ne-KN.Okubizwa nge-KP kungavikela izinhlayiya ezinamafutha nezingezona amafutha, kuyilapho i-KN ingavikela kuphela izinhlayiya ezingezona amafutha.

Lesi isingeniso se-ffp2 imaskhi vs pm2.5.Uma ufuna ukwazi okwengeziwe ngamamaski e-FFP2, sicela ukhululeke ukusithinta.
