Deicing tus neeg sawv cev tuaj yeem siv ob txoj hauv kev: kev sib kis qhuav thiab tshuaj tsuag tshuaj. cov
Qhuav kis: Tshaj tawm tus neeg sawv cev deicing ntawm cov daus manually lossis mechanically. Cov ntaub ntawv sib kis tus nqi rau cov daus nrog cov daus poob qis dua 50 hli yog 30-50 g / m2, thiab thaum cov daus siab tshaj 50 hli los yog qhov kub thiab txias tsawg dhau, qhov sib kis los yog cov sij hawm yuav tsum tau nce ntxiv. 1
Txau cov tshuaj: Npaj tus neeg sawv cev deicing rau hauv 20% aqueous tov thiab tshuaj tsuag rau ntawm cov daus. Thaum cov daus poob qis dua 50 hli, qhov kev siv tshuaj tsuag yog 0.4 litres / m2, thiab thaum cov daus poob siab tshaj 50 hli los yog qhov kub thiab txias tsawg dhau, qhov concentration lossis cov sij hawm yuav tsum tau nce kom tsim nyog.
Kev ceev faj rau kev siv:
Kev tiv thaiv ib puag ncig thiab kev tiv thaiv txoj kev: Sim siv cov cua sov saum npoo, hnub ci hluav taws xob hluav taws xob thiab cov cua sov tso tawm los ntawm lub tsheb nws tus kheej thaum tsav tsheb los pab cov daus ntawm txoj kev. Cov snowmelt yuav tsum tau kis ntau tshaj li 1.5 meters deb ntawm txoj kev thaiv sab nraum txoj kev, los yog laj kab yuav tsum tau teem rau ntawm ob sab ntawm txoj kev uas tsim nyog los tiv thaiv cov snowmelt los ntawm splashing mus rau qhov chaw ntsuab. Kev puas tsuaj los daus: Hauv cov xwm txheej tshwj xeeb xws li kev puas tsuaj los daus, feem ntau ntawm cov daus hauv av yuav tsum tau muab tshem tawm nrog cov daus ua ntej siv cov snowmelt.
Kev tshem tawm thiab muab pov tseg raws sij hawm ntawm qhov chaw tsim nyog: Snowmelt yuav tsum tau muab tshem tawm hauv lub sijhawm tom qab siv thiab muab pov tseg rau ntawm qhov chaw. Kev siv cov snowmelt yuav tsum txwv tsis pub nyob rau hauv cov chaw tseem ceeb.
Los ntawm kev ua raws li cov txheej txheem no thiab kev ceev faj, snowmelt tuaj yeem siv tau zoo dua thaum txo kev cuam tshuam rau ib puag ncig thiab cov neeg ua haujlwm.
