Imaski yokhuselo lwezonyango

Ihambelana nomgangatho we-GB19083-2003 "IiMfuno zobuGcisa kwiiMaski zoKhuseleko lwezoNyango". Izibonakaliso zezobugcisa ezibalulekileyo zibandakanya ukusebenza kakuhle 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% ye-NFP, engaphezulu kwe-NFP25, engaphezulu kwe-NFP25 (2) Ukuchasana nokuphefumula: Ngaphantsi kweemeko ezihamba phambili ezingentla, ukuchasana kokuphefumula akudluli i-343.2Pa (35mmH2O).

Iimaski zotyando lwezonyango

Ngokuhambelana nomgangatho we-YY 0469-2004 "IiMfuno zobuGcisa kwiMaski yoNyango lwezoNyango", izikhombisi ezibalulekileyo zobugcisa ziquka ukusebenza kakuhle kokucoca, ukucocwa kwebhaktheriya kunye nokumelana nokuphefumla: (1) Ukusebenza kakuhle kokucoca: phantsi kwemeko yokuhamba komoya (30 ± 2) L/min, Ukusebenza kakuhle kokucoca kwesodium chloride. akukho ngaphantsi kwe-30% (2) Ukuphumelela kokuhluza ibhaktheriya: phantsi kweemeko ezichaziweyo, i-avareji ye-particle diameter yi (3±0.3)μm yegolide etyheli Ukuphumelela kokuhluzwa kwe-aerosol ye-staphylococcal ayikho ngaphantsi kwe-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 ngo-8^th, 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 wemvelisoikhephu iingoma ezihambayokwayeiingoma zerobhothi. Ngeenyembezi nokubila, sivuyiswa kukubona sikhula.

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