Imigangatho yokuhlola iimaski zonyango

Imaski yokhuselo lwezonyango

Ihambelana nomgangatho we-GB19083-2003 "IiMfuno zobuGcisa kwiiMaski zoKhuseleko lwezoNyango". Iimpawu ezibalulekileyo zobugcisa ziquka ukuphumelela kokucoca i-particle non-oily kunye nokuchasana nokuhamba komoya: (1) Ukusebenza kakuhle kokucoca: Ngaphantsi kwemeko yokuhamba komoya (85±2) L/min, i-aerodynamics Ukusebenza kakuhle kokucoca i-aerosol ye-sodium chloride kunye nobubanzi obuphakathi ( 0.24±0.06)μm ayikho ngaphantsi kwe-95%, ehambelana ne-N95 (okanye i-FFP2) nangaphezulu. (2) Ukuchasana nokuphefumula: Ngaphantsi kweemeko ezihamba phambili ezingentla, ukuchasana kokuphefumula akudluli i-343.2Pa (35mmH2O).

Iimaski zotyando lwezonyango

Ngokuhambelana ne-YY 0469-2004 "IiMfuneko zobuGcisa kwiiMaski zoNyango lwezoNyango" umgangatho, izibonakaliso ezibalulekileyo zobugcisa zibandakanya ukusebenza kakuhle kokucoca, ukusebenza kakuhle kwe-bacterial filtration kunye nokumelana nokuphefumula: (1) Ukusebenza kakuhle kokucoca: phantsi kweemeko zokuhamba komoya (30 ± 2) L. /min, Ukusebenza kakuhle kokuhluzwa kwe-aerosol ye-sodium chloride ene-kinetic median diameter (0.24±0.06)μm ayikho ngaphantsi kwe-30% (2) Ukuphumelela kokuhluza ibhaktheriya: phantsi kweemeko ezikhankanyiweyo, i-avareji ye-particle diameter yi (3±0.3)μm yegolide tyheli Ukuphumelela kokuhluzwa kwe-aerosol ye-staphylococcal akukho ngaphantsi kwama-95%; (3) Ukuchasana nokuphefumula: Ngaphantsi kwemeko yokusebenza kakuhle kokucoca kunye nesantya sokuhamba, ukuchasana kwe-inhalation akudluli i-49Pa kwaye ukuchasana nokuphefumula akudluli i-29.4Pa.
3. Iimaski zonyango eziqhelekileyo
Ukuthobela imigangatho yemveliso ebhalisiweyo ebhalisiweyo (YZB), ngokubanzi ayinayo imfuneko yokusulungekisa amasuntswana kunye neebhaktheriya, okanye iimfuno zokusefa okusebenzayo kwamasuntswana kunye neebhaktheriya ziphantsi kuneemaski zotyando kunye neemaski zokhuselo lwezonyango.

Ngathi

Phambi komzi-mveliso weGator Track, singu-AIMAX, umthengisi weengoma zerabha ngaphezulu kweminyaka eli-15. Ukutsalwa kumava ethu kweli candelo, ukukhonza ngcono abathengi bethu, siye saziva sifuna ukwakha umzi-mveliso wethu, kungekuko ukufuna ubungakanani esinokuwuthengisa, kodwa kwingoma nganye elungileyo esiyenzileyo kwaye siyenze ibalwe.

Kwi-2015, i-Gator Track yasekwa ngoncedo lweenjineli ezizityebi ezinamava. Ingoma yethu yokuqala yakhiwe nge-8th, Matshi, 2016. Kuba iyonke eyakhelwe 50 izitya 2016, ukuza kuthi ga ngoku kuphela ibango 1 1 pc.

Njengomzi-mveliso omtsha kraca, sinazo zonke izixhobo ezitsha zobukhulu bobukhulu beengoma ze-excavator, iingoma zokulayishwa, iingoma zokulahla, iingoma ze-ASV kunye neepadi zerabha. Kutsha nje songeze umgca omtsha wemvelisoiingoma zekhephu ezihambayokwayeiingoma zerobhothi. Ngeenyembezi nokubila, sivuyiswa kukubona sikhula.

Sijonge phambili kwithuba lokufumana ishishini lakho kunye nobudlelwane obude, obuhlala buhleli.
