Imaski yokuhlunga ingxenye yengxenye (8228V-2 FFP2)
Ukwakheka kwezinto
Ungqimba olungaphezulu yindwangu engalukiwe engu-45g.Isendlalelo sesibili siyisihlungi se-45g FFP2.Ungqimba lwangaphakathi luwu-220g we-acupuncture cotton.
Yiziphi izinzuzo zamaski ezinama-valve okuphefumula?
I-valve yokuphefumula yemaski ifanele indawo eshisa kakhulu.Kuzophefumula kakhulu lapho uphefumula, futhi i-valve yokuphefumula yokuphefumula izovala ngokuzenzakalelayo, okungeke kuthinte umphumela wokusetshenziswa nhlobo.
Uma kuqhathaniswa namamaski obuso ajwayelekile, imaski enamavalvu okuphefumula ifaneleka kakhulu endaweni esetshenziswayo enokhahlo futhi ikhuthaza kakhulu ukuphefumula kwabantu.Endaweni yokusebenza eswakeme futhi eshisayo lapho kungena umoya omncane noma inani elikhulu lomsebenzi, ukusebenzisa imaski enevalvu yokuphefumula kungakusiza uzizwe ukhululekile lapho ukhipha umoya.
Umgomo wokusebenza kwe-valve yokuphefumula ukuthi ukucindezela okuhle kwegesi ekhishiwe kuvula ipuleti ye-valve lapho uphefumula, ukuze kuqedwe ngokushesha igesi ewudoti emzimbeni futhi kuncishiswe umuzwa ogcwele futhi oshisayo lapho usebenzisa imaski.Ukucindezela okungalungile lapho uhogela kuzovala ngokuzenzakalelayo i-valve ukugwema ukuhogela ukungcola okuvela endaweni engaphandle.
Imaski yobuso enokotini we-acupuncture
Ukotini we-acupuncture ubizwa nangokuthi inaliti ye-punch eyenza ukotini embonini ye-mask yobuso obulahlwayo.Inaliti ebhontshiwe ikotini yemaski iwuhlobo lwempahla yemaski eyenziwe ngenqubo yokudinga.Ibuye ibizwe ngemaski evikela uthuli ngemuva kokuhlanganiswa nokucubungula imaski.Inaliti ebhontshiwe ikotini ye-mask iwuhlobo lwezinto zokuhlunga, ezenziwe nge-polyester fiber ngenqubo yokubhoboza inaliti.Enqubweni yokudlula kule nto yokuhlunga, uthuli lokuphefumula luzokhangiswa phakathi kwemicu, edlala indima ekuvimbeleni uthuli.
Izimaski zikakotini ezinenaliti zilungele izimayini, ukwakhiwa, imboni, ukugaya kanye nemboni yezemithi, ezolimo nezolimo, amahlathi nokufuywa kwezilwane, ubunjiniyela besitimela esingaphansi komhlaba, ukusebenza kwe-aluminium, okokusebenza kwe-elekthronikhi nogesi, ukukhiqiza insimbi kanye nezinsimbi, imboni yokucubungula ukudla, imboni kasimende, imboni yendwangu, imboni yamathuluzi nehardware, ukugaya insimbi yeshidi, ukupholisha, ukusika, ubunjiniyela bokuhlakaza, ukusebenza kokuchotshozwa.Bangakwazi ukuvimbela ngempumelelo izinsimbi ezingezona ayoni, izinsimbi ezisindayo nezinye izinto ezingcolile eziyingozi, futhi bavimbe i-glass fiber Asbestos nezinye izinto eziyingozi.
Umehluko wengcindezi ungenye yezindlela zokuhlola zokuhlola imaski.
Indlela yokuhlola - Umehluko wokucindezela
Umehluko wengcindezi, noma ukwehla kwengcindezi, kubonisa ukuthi kulula kangakanani ukuphefumula ngezinto zokuhlunga.Umehluko wengcindezi ngokuvamile unqunywa ngokulinganisa ingcindezi yomoya ezinhlangothini zombili zezinto zokuhlunga kuyilapho umoya ugeleza ngesivinini esaziwayo ngezinto zokuhlunga.Umehluko wengcindezi umehluko phakathi kwezingcindezi zomoya ezimbili.Umehluko wengcindezi ephansi usho ukuthi umoya udlula kalula ezintweni zokuhlunga, okwenza kube lula ukuphefumula.Ngokusetha okunikezwayo kokuhlola, ukwehlisa isivinini somoya kuzonciphisa umehluko wengcindezi futhi ukukhulisa ukushuba kwezinto zokuhlunga kuzonyusa umehluko wengcindezi.
Umehluko wengcindezi uvame ukubikwa kumayunithi e-pascal (Pa) (1.0 Pa = 0.102 mmH2O).Ezinye izindinganiso zokuhlukanisa ingcindezi kumamaski okuhlinzwa zisebenzisa iyunithi ye-Pa/cm2, engenayo incazelo ebonakalayo.Lezi zivivinyo, nokho, zicacisa indawo engaphezulu yempahla yemaski ehloliwe, ngakho-ke amanani aphindwe ngendawo engaphezulu ehloliwe ukuze kutholwe iyunithi enengqondo ngokomzimba, i-Pa.
EN 149:2001
E-Europe, ama-respirator acwengayo kufanele abe nezici ezikhonjiswe yi-EN 149:2001 (+ A1: 2009) standard, egunyaza ukuthi lezi zimaski, phakathi kwezinye izinto, kumele zibe nezici ezithile zokuphefumula, ukuvuza kwangaphakathi, ukuvutha, ukunqwabelana kwe-CO2. , njll. Izinga le-EN 149:2001 (+ A1: 2009) lidinga ukuthi amandla okuhlunga amamaski ahlolwe kokubili nge-aerosol yezinhlayiya ze-NaCl ezinobubanzi obumaphakathi bokusabalalisa phakathi kuka-0.06 no-0.10 μm kanye ne-aerosol yezinhlayiyana zikapharafini. uwoyela onokusabalaliswa kobubanzi obumaphakathi phakathi kuka-0.29 no-0.45 μm;akukho ukuhlolwa kwe-bacterial filtration edingekayo.Ngokusekelwe kumthamo wazo wokuhlunga, ama-facepiece respirator ahlukaniswa ngohlobo lwe-FFP1 (umthamo wokuhlunga we-NaCl aerosol namafutha kapharafini alingana no-80%), i-FFP2 (umthamo wokuhlunga we-NaCl aerosol namafutha kapharafini alingana no-94%) kanye ne-FFP3 (umthamo wokuhlunga. ye-aerosol ye-NaCl namafutha kapharafini alingana no-99%).
