Kune marudzi akawanda emasiki ekurapa.Tinogona kuzvipatsanura muzvikamu zvitatu.Ndezvipi zvikamu zvitatu?Iye zvinomedical face mask wholesaleinotiudza zvinotevera.

MedicalFFP2 masksanonyanya kugadzirwa nechikamu chimwe chete kana akawanda ejira risingarukwa.Iwo makuru ekugadzira maitiro anosanganisira kunyungudutswa-kuvhuvhuta, spunbond, mhepo inopisa kana inodiwa.Inoshingirira kune zvinwiwa, kusefa tunhu uye mabhakitiriya.Ijira rekudzivirira rekurapa.

Masks ekurapa anogona kukamurwa kuita masks ekudzivirira ekurapa, masiki ekuvhiya uye akajairwa masiki ekurapa zvinoenderana nemaitiro avo ekuita uye chiyero chekushandisa.

Mask inodzivirira yezvokurapa

Iyo utility modhi inoenderana neyakavharika-yakakodzera-yega-priming sefa yekudzivirira yekurapa mudziyo, wakakodzera kuchengetedzwa kwevashandi vekurapa uye vane hukama nevashandi, uye ine giredhi redziviriro yepamusoro, uye inonyanya kukodzera kuvarwere vanobatwa nechirwere chekufema. zvirwere zvinotapurirwa nemhepo kana pedyo nemadonhwe muchirongwa chekuongororwa uye kurapwa.Inogona kusefa kunze zvidimbu mumhepo uye kuvhara madonhwe, ropa, zvinwiwa zvemuviri, zvakabuda, nezvimwe. Ichi chigadzirwa chinoraswa.Masks ekurapa anovharisa mabhakitiriya mazhinji, mavhairasi uye mamwe hutachiona, uye WHO inokurudzira kuti vashandi vehutano vashandise masks anorwisa-particulate kudzivirira kutapukirwa nehutachiona mumhepo yechipatara.

Zvinoenderana nezvinodiwa zvetekinoroji zveGB19083-2003, iwo makuru tekinoroji indexes emasiki ekudzivirira ekurapa ndeyekusefa uye kuramba kuyerera kwemhepo ine kana isina zvidimbu zvemafuta.

Zvakananga zviratidzo ndezvizvi:

1) Kushanda kwefiltration: kana kuyerera kwemhepo kuri (85 ± 2) L/min, kukwenenzverwa kwesefa hakusi pasi pe95%, kureva, iyo aerodynamic median dhayamita yeN95 (kana FFP2) uye pamusoro (0.24± 0.06) μm(0.24±0.06).Kutapurirana nemhepo kunogona kudzivirirwa nehutachiona hwe5μm muhupamhi kana nekubatana kwepedyo nehutachiona hwehutachiona hunoparadzirwa nemadonhwe.

2) Suction resistance: pasi pemamiriro ekuyerera ari pamusoro, kusveta kupikisa hakufaniri kudarika 343.2Pa (35mmH2O).

3) Hapafanirwe kunge paine zviratidziro zvehunyanzvi senge permeability mukati memasikisi pasi pe10.9Kpa (80mmHg) kumanikidzwa.

4) Iyo maski inofanirwa kuve yakashongedzerwa nemhino clip, yakagadzirwa nepurasitiki zvinhu, kureba> 8.5 cm.

5) ropa rekugadzira rinofanirwa kupfapfaidzwa pa10.7kPa (80mmHg) mumuenzaniso wemasiki.Panofanira kunge pasina kupinda mukati me mask.

mask yekuvhiya

Iyo mask yekuvhiya yekurapa inonyanya kushandiswa kuchengetedza kwekutanga kwevashandi vekurapa kana vashandi vanoenderana, pamwe nemaitiro ekudzivirira ekudzivirira kutapurirana kweropa, mvura yemuviri, kupfapfaidza uye zvichingodaro, paine kumwe kudzivirira.Inonyanya kupfekwa munzvimbo dzakachena pazasi pechikamu che100,000, ichishanda mukamuri yekuvhiya, varwere vanoyamwisa vane immune immune, vachiita bhomba remuviri uye mamwe maoparesheni.Masks ekurapa anogona kuvhara mabhakitiriya mazhinji uye mavhairasi kudzivirira kutapukirwa kwevashandi vekurapa, uye zvakare kudzivirira hutachiona hunotakurwa nemweya wevashandi vekurapa kubva pakuburitswa kunze kwemuviri, zvichiunza njodzi kumurwere.Masks ekuvhiya anodiwa kuti aite zvinopfuura makumi mapfumbamwe neshanu muzana pakusefa mabhakitiriya.Masks ekuvhiya anoraswa anofanirwa kupihwawo kune varwere vanofungidzirwa kuti vane zvirwere zvekufema kudzivirira kutyisidzira kwehutachiona kune vamwe vashandi vechipatara uye kuderedza njodzi yekutapukirwa, asi mhedzisiro yacho haina kunaka semasiki ekudzivirira ekurapa.

Yakakosha tekinoroji zviratidzo zvinosanganisira kusefa kunyatsoita, bhakitiriya kusefa kunyatsoita uye kuramba kufema.

Zvakananga zviratidzo ndezvizvi:

1) Kufefeta zvakanaka: Aerodynamic median dhayamita (0.24±0.06) μm sodium chloride aerosol kusefa kushanda zvakanaka hakusi pasi pe30% pakuyerera kwemhepo (30±2)L/min.

2) Bacterial filtrate kunyatsoshanda: kusefa kweStaphylococcus aureus neavhareji yehukuru hwe (3±0.3) micron haifanire kunge iri pasi pe95%, hutachiona hwekusefa ≥95%, uye mwero wekusefa kweasina mafuta ≥30. %.

3) Kupokana kwekufema: pasi pemamiriro ekusefa kwekubudirira kuyerera, kufemerwa kupikisa hakuzopfuure 49Pa, uye kuramba kwekufema hakupfuure 29.4Pa.Kana mutsauko wekumanikidza △P pakati pemativi maviri emasiki iri 49Pa/cm, mwero wekuyerera kwegasi unofanirwa kunge uri ≥264mm/s.

4) Mhino clip uye mask strap: Iyo maski inofanirwa kuve yakashongedzerwa nemhino clip yakagadzirwa nepurasitiki zvinhu, kureba kwemhino clip kunofanirwa kunge kwakakura kupfuura 8.0cm.Bhandi remasiki rinofanira kunge riri nyore kupfeka uye kubvisa, uye simba rekupwanya remasiki bhandi rega rega rinofanira kunge rakakura kupfuura 10N panzvimbo yekubatanidza yemuviri wemasiki.

5) kupinda kweropa rekugadzira: mushure mokunge 2ml yeropa rekugadzira yakapfapfaidzwa kune rumwe rutivi rwekunze kwemasikisi pa 16.0kPa (120mmHg), hapafaniri kuva nekupinda mukati memukati wemasikisi.

6) Flame retardant performance: Shandisa zvisingabatike zvemasiki, uye pisa zvisingasviki 5s mushure mekunge mask yasiya murazvo.

7) Ethylene oxide residue: iyo ethylene oxide yakasara yemasikisi akaomeswa inofanira kunge iri pasi pe10μg/g.

8) Kushatirwa kweganda: iyo yekutanga kutsamwisa indekisi yemasiki zvinhu inofanira kunge iri pasi kana kuenzana ne0.4, uye hapafanirwe kuve nekuita sensitization.

9) Microbial index: nhamba yose yebhakitiriya makoroni ≤20CFU/g, coliform bacteria, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococcus uye fungi hazvizoonekwi.

Mask yekurapa yakajairika

General ekurapa masks akagadzirirwa kuvharira kubuda kubva mumhino nemuromo uye anogona kushandiswa kamwe-kushandiswa mune zvakajairika zvekurapa Zvirongwa zvine yakaderera mwero wedziviriro.Zvezviitiko zvehutano zvakajairwa, sekuchenesa hutsanana, kugadzirira mvura, mibhedha yekuchenesa mibhedha, kuzviparadzanisa nevamwe kana kudzivirira zvimedu zvisiri zvehutachiona hwepathogenic, senge mukume, nezvimwe.

Zvinoenderana neakakodzera akanyoreswa chigadzirwa Mayero (YZB), kusefa kwezvimedu uye mabhakitiriya hakuwanzo kudikanwa, kana kusefa kwezvimedu uye mabhakitiriya kwakadzikira pane kuya kwemasiki ekuvhiya uye masks ekudzivirira ekurapa.Iyo 0.3-micron-diameter aerosol inogona chete kuwana 20.0% -25.0% yekudzivirira maitiro, iyo isingakwanise kuwana kusefa kwekuita kwezvimedu uye mabhakitiriya.Haikwanise kudzivirira zvinobudirira pathogen kubva mukupumha turakiti kupinda, haigone kushandiswa mukiriniki yekushungurudza mashandiro, haigone kutamba chikamu chekudzivirira pane zvimedu uye mabhakitiriya uye mavhairasi, inogona chete kutamba mechanical chipingamupinyi basa paguruva particles kana aerosols.

Zviitiko zvekushandisa zvakasiyana

Masks ekudzivirira ekurapa:

Iyo utility modhi yakakodzera kuchengetedzwa kwebasa kwevashandi vekurapa vachisangana nevarwere vane mweya kana droplet zvirwere zvinotapuriranwa.Zvinowanzokurudzirwa kutsiviwa mukati meawa 4 mumawadhi ekuzviparadzanisa nevamwe, mudzimba dzevanorwara zvakanyanya, makiriniki efivha nedzimwe nzvimbo dzakakosha.

Masks ekuvhiya:

Yakakodzera kupfekwa nevashandi vezvokurapa mumakiriniki ekurapa, marabhoritari, makamuri ekuvhiya uye dzimwe nzvimbo dzinopinda kana dzinoda kudzivirira ropa, kuputika kwemvura yemuviri uye kutapurirana kwefuro, uye kudzivirira kwedenda reropa kunodiwa kunze kwayo.Enda kunzvimbo dzeveruzhinji, usabata varwere, unofanirwa kupfeka mask yekuvhiya;

Masks ekurapa anoraswa:

Inoshandiswa muhutano hwehutano kune vanhu vane njodzi yakaderera uye ine yakaderera mazinga ekudzivirira.Iyo inogumira pakutamba imwe mechanic barriers effect paguruva kana aerosol uye inopfekwa kana iri diki density yehuwandu.

Izvo zviri pamusoro apa ipfupi sumo yemasiki ekurapa.Kuti uwane rumwe ruzivo nezve maski ekurapa, ndapota taura neyeduvanogadzira maski kumesokuti ndikupe iwe ruzivo rwakadzama
