Iyini imaski ye-FFP2|KENJOY

Awukwazi ukuphuma ngaphandle kokugqoka imaskhi, kodwa yini abantu abaningi abayaziyo ngabo?Okulandelayo incazelo yeFFP2 imaskingumthengisi wezimaski.

Eqinisweni, imaski ye-European standard FFP2, okungenye yezindinganiso ze-EN149:2001, iyisisetshenziswa sokuvikela sezokwelapha esilahlwayo esisebenza kahle ngokuhlunga esingu-94% noma ngaphezulu futhi singavimba ama-aerosol ayingozi ngaphandle kokuhogelwa.Imaski ye-FFP2 iphume isibili, ibanga eliphakeme kakhulu kube yi-FFP3 (ukuhlungwa okungaphansi kwamaphesenti angama-97) kanye nebanga eliphansi kube yi-FFP1 (ukuhlunga okuncane).

Isetshenziselwa ini i-FFP2

1. Izihloko zokuzivikela zenzelwe ukuvimbela noma ukunciphisa uthuli olusemoyeni ukuthi lungangeni ezithweni zokuphefumula zomuntu, ukuze kuvikelwe ukuphepha kwempilo;

2, impahla: imaski elwa nezinhlayiyana ikakhulukazi isebenzisa izingqimba ezimbili zendwangu engalukiwe ngaphakathi nangaphandle, ungqimba oluphakathi lwendwangu yokuhlunga (indwangu encibilikisiwe) isakhiwo;

3, isimiso sokuhlunga: ukuhlungwa kothuli olucolisekileyo kuncike kakhulu phakathi kwendwangu yokuhlunga, ngoba indwangu encibilikile inezici ze-electrostatic, ingakwazi ukumunca izinhlayiya ezincane ezinhle.Ngenxa yokukhangiswa kothuli entweni yokuhlunga, into yokuhlunga ayikwazi ukuhlanzwa ngogesi omile, futhi into yokuhlunga idinga ukushintshwa njalo.

4. Qaphela: Ukusetshenziswa kwezifihla-buso zothuli ekhaya nakwamanye amazwe kuqinile impela, phakathi kwazo i-anti-particle mask ingeyezinga lokuqala, eliphakeme kunama-muffs endlebeni kanye nezibuko zokuzivikela.Isitifiketi sokuhlola esigunyazwe kakhulu sinesitifiketi se-European CE nesitifiketi se-NIOSH sase-United States, kanye nezinga le-NIOSH lase-United States liyafana.

5. Izinto zokuvikela: Izinto zokuvikela zihlukaniswe nge-KP ne-KN, i-KP iyakwazi ukuvikela izinhlayiya ezinamafutha nezingezona amafutha, kuyilapho i-KN ikwazi kuphela ukuvikela izinhlayiya ezingezona amafutha.

6, Ibanga lokuvikela: Ibanga lokuvikela laseChina lihlukaniswe i-KP100, KP95, KP90 ne-KN100, KN95, KN90.Phakathi kwazo, i-KP100 ne-KN100 inokuhlunga okuphezulu kakhulu okungaphezulu kuka-99.97% ngokwezinga likazwelonke, ngakho-ke inokuphepha okuphezulu kakhulu okungasetshenziswa.

Khetha indlela

1. umphumela wokuvikela imaski muhle.Ukusebenza kahle kokuvimbela uthuli kwemaski kusekelwe ekusebenzeni kwayo kokuvimba othulini olucolekile, ikakhulukazi uthuli oluphefumulayo olungaphansi kuka-5μm.Umgomo wokuvimbela uthuli lwemaski ye-gauze ukuhlunga ngomshini, okungukuthi, lapho uthuli ne-gauze kushayisana, ezinye izinhlayiya ezinkulu zothuli zizovimba ungqimba ngongqimba.Kodwa uthuli oluhle, ikakhulukazi uthuli olungaphansi kuka-5μm, ludlula emithanjeni ye-gauze bese lungena ohlelweni lokuphefumula.Emakethe yokuthengisa, kunezinto ezimbalwa zokuhlunga eziqukethe ugesi omile unomphela, okokuhlunga kuyifayibha equkethe ugesi omile unomphela, uthuli oluphefumulayo olungaphansi kwama-microns angu-5 ngale nto yokuhlunga, lukhangwa ugesi omile, i-adsorption ezintweni zokuhlunga, ngempela iqhaza ekuvimbeleni uthuli.

2. imaski nesimo sobuso eduze nezinga lokuhle.Njengoba imaski ingaxhumene eduze nobuso, uthuli oluphuma emoyeni luzongena endleleni yomoya ngezikhala ezizungeze imaski.Ngakho-ke, abantu kufanele bakhethe imaski elwa nezinhlayiyana ngokuhambisana nokwakheka kobuso babo, futhi bagqoke imaski yothuli ngendlela efanele.

3. Gqoka ngokunethezeka, okuhlanganisa ukumelana nokuphefumula okuncane, isisindo esilula, ukugqoka impilo, ukulungiswa okulula, njengokugqoka i-arch anti-particulate mask.

Okungenhla isingeniso esifushane samamaski e-FFP2.Uma ufuna ukwazi okwengeziwe ngamamaski, sicela uxhumane nathiumphakeli wemaski wezokwelapha.Sikholelwa ukuthi uzothola impendulo egculisayo.
