Ndezvipi zvinobatsira zvemasikisi ane mavharuvhu ekufema?
Iyo mask yekufema valve yakakodzera kune imwe nzvimbo inopisa.Ichanyanya kufema kana uchifema, uye iyo inhalation yekufema valve inovhara yega, iyo isingazokanganisa mashandisiro ekushandisa zvachose.
Kuenzaniswa nemasiki echiso akajairwa, masiki ane mavharuvhu ekufema akanyanya kukodzera kune hutsinye nharaunda yekushandiswa uye anobatsira pakufema kwevanhu.Munzvimbo yekushanda ine hunyoro uye inopisa ine mhepo isina kusimba kana kuwanda kwekushanda, kushandisa mask ine vharafu yekufema kunogona kukubatsira kuti unzwe wakasununguka paunenge uchifema.
Basa rekushanda kwevharuvhu yekufema ndeyekuti kudzvanywa kwakanaka kwegasi rinobuda kunovhuvhuta ndiro yevhavha painofema, kuitira kuti ikurumidze kubvisa gasi remarara mumuviri uye kuderedza kunyungudika uye kupisa kunzwa paunenge uchishandisa mask.Kumanikidza kwakashata kana kufemesa kunozongovhara vharuvhu kudzivirira kufemesa zvinosvibisa kubva kune kunze kwezvakatipoteredza.

Tsono dzakaroverwa masiki ekotoni dzakakodzera kumigodhi, kuvaka, kuwanikwa, kukuya uye indasitiri yemishonga, kurima uye horticulture, masango nekuchengeta mhuka, subway engineering, aluminium kushanda, zvemagetsi nemagetsi, chiridzwa uye chiridzwa kugadzira, indasitiri yekugadzira chikafu, simende chirimwa, textile plant, tool and hardware plant, sheet metal kugaya, polishing, cutting, disassembly engineering, kupwanya basa.Vanokwanisa kudzivirira zvinobudirira simbi dzisina-ferrous, heavy metals nezvimwe zvinosvibisa zvinosvibisa, uye block glass fiber Asbestos nezvimwe zvinokuvadza.
Kudzvanya musiyano ndiyo imwe yenzira dzekuyedza yekuongorora mask.
Kuedza nzira - Kudzvanya musiyano
Musiyano wekumanikidza, kana kudonha kwekumanikidza, kunoratidza kuti zviri nyore sei kufema kuburikidza nesefa zvinhu.Musiyano wedzvinyiriro unowanzo kutariswa nekuyera kudzvanywa kwemhepo pamativi ese echigadzirwa chesefa apo mweya unoyerera pane inozivikanwa velocity kuburikidza nesefa zvinhu.Musiyano wekumanikidza ndiwo mutsauko pakati pezviviri zvemhepo.Musiyano wepasi-mutsindo unoreva kuti mweya unopfuura nyore kuburikidza nesefa zvinhu, zvichiita kuti zvive nyore kufema.Kune yakapihwa yekuyedza set-up, kudzikisira mhepo yemhepo kunoderedza kudzvanywa kwakasiyana uye kuwedzera ukobvu hwesefa zvinhu kuchawedzera kudzvanywa kwakasiyana.
Musiyano wekumanikidza unowanzo kutaurwa muzvikamu zvepascal (Pa) (1.0 Pa = 0.102 mmH2O).Mimwe yekumanikidza yekusiyanisa zviyero zvemasiki ekuvhiya inoshandisa iyo unit yePa/cm2, iyo isina chirevo chemuviri.Iyi bvunzo, zvisinei, inotsanangura nzvimbo yepasi yemask zvinhu zvakaedzwa, saka kukosha kwacho kwakawedzera neiyo nzvimbo yakaedzwa kuti iwane inorevesa yemuviri unit, Pa.
