Nei chitupa cheffp2 chanetsa kuwana|KENJOY

Pamusoro pemubhadharo wepamusoro wekuyedza, nzvimbo dzekuyedza muEurope, nguva refu yekuita uye zvimwe zvinhu, iwo akaomesesa ekuyedza zviyero akadzora vazhinji vanogadzira mask.ZvinoteveraFFP2 mask filtration kunyatsoita bvunzo uye kufema kuramba bvunzo semienzaniso kuratidza yakakwira mwero wekuyedzwa.

Tsanangudzo yakajairwa yeFFP2 inodzivirira kufema

Masiki ekudzivirira eEuropean neAmerica anosarudzwa kuti aedzwe neAmerican TSI-8130Automated Filter Testers zviridzwa.IAmerican standard class N inoshandisa nzira yeNaCl, kirasi R inoshandisa nzira yeDOP, uye European standard inoshandisa nzira yeDOP.Kuedza kweEurope kunoshandisa mafuta eDOP kugadzira guruva.Iyo dhayamita yeDOP oiri zvimedu ndeye 0.33 μ m, iyo yekuverenga avhareji dhayamita ndeye 0.20 μ m, uye kusefa kwakanaka kunodiwa kuve isingasviki 94%.Kune rumwe rutivi, iyo filtration effect ine hukama nehukuru hwechidimbu, mukuwedzera, inobatwawo nekuti zvimedu zvine mafuta here kana kuti kwete.

Pamusoro pezvo, iyo EU mweya yekuyedza zviyero zveFFP2 zvifemuro zvakare zvakaomesesa.Iyo yekufemerwa yekupikisa bvunzo inoshandisa kuyerera kwe95L/min uye iyo expiratory resistance test inoshandisa kuyerera kwe160L/min.Kwakadaro kuomarara kusefa kuita uye kufema kupikisa zviyero zvinoita kuti vagadziri vazhinji vadzoke pasi zvakananga.

Zvitsva zvepamusoro-yekupedzisira nano-zvinhu

Iwo akaomesesa bvunzo zviyero zvekusefa kunyatsoita uye kufema kuramba kunoita kuti FFP2 masiki ave nepamusoro zvinodiwa zvesefa zvinhu.Kushanda kwesefa kwakaedzwa neDEKRA kudarika 96%.Inochengetedza hutano hwevanhu nekusefa nekuvhara kupinda kwezvinhu zvinokuvadza zvakaita seguruva, mabhakitiriya, mavhairasi uye zvimedu zvine mafuta mumhepo.The surface morphology of the new nano-material is a spider-web-like microporous structure, inova inoshanduka uye elastic microporous material ine high porosity, yunifomu pore size distribution, air permeability uye mvura permeability.Panguva imwecheteyo, ine zvakare basa rekufema kuti ive nechokwadi chekunyaradza kwekupfeka.Izvo zvinhu ndeyepamusoro-inoshanda zvinhu zvine tembiricha kuramba, corrosion kuramba, kuomarara kwakanyanya uye simba, uye yakanaka biocompatibility.Iyo fiber uye saizi yepore ye nano-material iri munhanho ye nanometer, uye inogona kuvharira zvakananga mabhakitiriya, mavhairasi uye guruva kuburikidza nekuita kwechivharo chemuviri.

Ndosaka iyo ffp2 chitupa ichinetsa kuwana.Kana iwe uchida kuziva zvakawanda nezve ffp2 masks, ndapota inzwa wakasununguka kutibata.
