Imaski yokuvikela yezokwelapha

Ihambisana nezinga le-GB19083-2003 “Izimfuneko Zobuchwepheshe Zamamaski Okuvikela Ezokwelapha”. Izinkomba zobuchwepheshe ezibalulekile zifaka ukusebenza kahle kokuhlunga kwezinhlayiyana ezingenawo amafutha kanye nokumelana nokugeleza komoya: (1) Ukusebenza kahle kokuhlunga: Ngaphansi kwesimo sokugeleza komoya (85±2) L/min, i-aerodynamics Ukusebenza kahle kokuhlunga kwe-aerosol ye-sodium chloride enobubanzi obuphakathi ( 0.24±0.06)μm ayikho ngaphansi kuka-95%, ehambisana ne-N95 (noma i-FFP2) nangaphezulu. (2) Ukumelana nokuphefumula: Ngaphansi kwezimo zokugeleza ezingenhla, ukumelana nokuphefumula akudluli i-343.2Pa (35mmH2O).

Imaski yokuhlinzwa yezokwelapha

Ngokuvumelana nezinga le-YY 0469-2004 “Izimfuneko Zobuchwepheshe Zamamaski Okuhlinzwa Kwezokwelapha”, izinkomba ezibalulekile zobuchwepheshe zihlanganisa ukusebenza kahle kokuhlunga, ukusebenza kahle kokuhlunga kwamagciwane kanye nokumelana nokuphefumula: (1) Ukusebenza kahle kokuhlunga: ngaphansi kwesimo sokugeleza komoya (30 ± 2) L /min, Ukusebenza kahle kokuhlunga kwe-aerosol ye-sodium chloride enobubanzi be-kinetic median (0.24±0.06)μm akukho ngaphansi kwama-30% (2) Ukusebenza kahle kokuhlunga kwebhaktheriya: ngaphansi kwezimo ezishiwo, isilinganiso sezinhlayiyana zobubanzi (3±0.3)μm okusagolide okusagolide Ukusebenza kahle kokuhlunga kwe-aerosol ye-staphylococcal akukhona ngaphansi kuka-95%; (3) Ukumelana nokuphefumula: Ngaphansi kwesimo sokusebenza kahle kokuhlunga kanye nezinga lokugeleza, ukumelana nokuhogela akudluli i-49Pa futhi ukumelana nokukhipha umoya akudluli i-29.4Pa.
3. Izifihla-buso ezivamile zezokwelapha
Ukuthobelana nezindinganiso ezifanelekile zomkhiqizo obhalisiwe (YZB), ngokuvamile azikho izidingo zokuhlunga kahle zezinhlayiya namagciwane, noma izimfuneko zokuhlunga kahle zezinhlayiya namagciwane zingaphansi komamaski bokuhlinzwa kanye nemaski okuvikela ezokwelapha.

Mayelana NATHI

Ngaphambi kwemboni ye-Gator Track, singama-AIMAX, abahwebi bamathrekhi enjoloba iminyaka engaphezu kwengu-15. Ngokuthatha kokuhlangenwe nakho kwethu kulo mkhakha, ukuze sikhonze kangcono amakhasimende ethu, saba nesifiso sokwakha ifektri eyethu, hhayi ngokuphishekela inani esingalithengisa, kodwa ngethrekhi ngayinye enhle esiwakhile futhi siyenze ibale.

Ngo-2015, i-Gator Track yasungulwa ngosizo lonjiniyela abanolwazi olucebile. Ingoma yethu yokuqala yakhiwe ngo-8^th, March, 2016. Engqikithini eyakhiwe iziqukathi ezingu-50 ngo-2016, kuze kube manje isimangalo esisodwa kuphela se-1 pc.

Njengefekthri entsha sha, sinamathuluzi amasha sha osayizi abaningi bamathrekhi e-excavator, ama-loader tracks, ama-dumper tracks, amathrekhi e-ASV namaphedi enjoloba. Muva nje sengeze umugqa omusha wokukhiqizaiqhwa amathrekhi eselulafuthiamathrekhi amarobhothi. Ngezinyembezi nezithukuthuku, sijabulela ukubona siyakhula.

Sibheke ngabomvu ithuba lokuzuza ibhizinisi lakho kanye nobudlelwano obude, obuhlala njalo.
