Kev kawm hauv chav kawm tam sim ntawd BREEN {{0} Zoo li cov roj twj tso kua mis, los yog txoj kev loj} Tsoos ua npuas ncauj qeeb pawg poob: lawv xav tau yaj, muaj cov sib txawv sib xyaw, lossis cov iav tshwj xeeb. Lub AFFF 3% yog tsim rau "npaj txhij (tsis muaj ua ntej {
1. Cov tsis muaj tseeb: kev xa tawm sai ua rau hauv cov lus qhia
Txhua qhov metric ntawm afff 3% series cov hom phiaj "tua neeg" hauv prepic thaum muaj xwm ceev. Ntawm no yog li cas txhua tus qauv txhawb nqa ceev ceev:
| Qauv Parieter | Afff 3% (-1 degree) | Afff 3% (-16 Qib) | Afff 3% (-35 degree) | Lub luag haujlwm hauv kev xa tawm sai |
|---|---|---|---|---|
| Khov taw tes | -1 degree | -16 Qib | -35 Degree | Tsis yaj -}} npaj siv hauv txias |
| Sib tov sib piv | Tsau 3% (3:97) | Tsau 3% (3:97) | Tsau 3% (3:97) | Tsis muaj sij hawm kho cov proportions |
| Viscosity | 15-20 CP (25 degree) | 18-23 cp (25 degree) | 20-25 Cp (25 Qib) | Tsis muaj viscosity -} ntws ntws ceev nrog txau |
| Cov khoom siv homogeneity | Tsis muaj kev txiav / sib cais | Tsis muaj kev txiav / sib cais | Tsis muaj kev txiav / sib cais | Tsis tshee / lim -} siv tam sim ntawd |
| Iav Tau | Ua haujlwm nrog cov tshuaj kuab quav | Ua haujlwm nrog cov laub txawb | Ua haujlwm nrog txias - cheeb tsam iav | Tsis tos tos cov khoom tshwj xeeb |
2. Rau me me spills (roj chaw nres tsheb, chaw ua haujlwm me me)
Me me, npaj txhij txog (piv txwv li, 2-10m² roj av nchuav) Yuav tsum ua npuas ncauj uas yooj yim mus lob thiab siv} Tsis muaj pab pawg ntawm cov kws tshaj lij ntawm cov kws tshaj lij ntawm cov kws tshaj lij.
- Zoo tshaj plaws haum: afff 3% (-1 degree)Nws ruaj 3% sib tov sib piv thiab sib xyaw nrog $ 50 Portable Tshuaj Tsuag US Cov Khoom Siv Roj Thauj Khoom Muag Khoom Siv 3M² roj av xau ntawm lub twj tso kua mis {}}}} 1 degree)) thiab tso nws hauv 10 vib nas this. Tus npuas lub 16.2 mn / m deg npoo nro kis tau ntau dua li hauv 20 vib nas this, muab cov nplaim taws me me rau cov hluav taws xob kom ncav cuag lub twj tso kua roj.
3. Rau nruab nrab nrawm fires (cov tsev muag khoom, logistics yards)
Nruab nrab - qhov me me blazes (10-50m², piv txwv li, cov kuab tshuaj lossis cov ua npuas ncauj uas tau txav nrawm nrawm nrawm.
- Qhov Zoo Tshaj: AFFF 3% (-16 Qib)Nws cov kev nthuav dav nruab nrab (6.6 ± 1) Cov nyiaj tshuav sib npaug thiab nrawm, thiab nws ua haujlwm nrog mobile ua npuasyuam (tsis muaj qhov ntsuas ruaj khov uas xav tau). Ib lub tsev lag luam hauv German muaj 25m² xim thinner spill uas igned {} willed} 16 degree) mus rau qhov chaw hose, thiab txau. Cov npaus yog 3.5-3.8 mn / m kis coefficition them rau re-{feeb kom muaj cov kua hluav taws xob tsis muaj zog ntxiv rau 40m² ua ntej kev hloov pauv tau pib.
4. Rau cold - thaj chaw deb ntawm hluav taws sai (kev loj, Arctic ua haujlwm chaw)
Hauv sub - xoom semps, piv txwv li txoj kev loj, arctic roj roam freezes, tawm hauv cov pab pawg daig.
- Qhov Zoo Tshaj: AFFF 3% (-35 degree)Nws -}} 35 Duritures kom khov taw tes txhais tau tias tsis muaj kuab koob txhais tau tias, txawm nyob rau hauv- 25 degrity huab cua. Ib chav tsev Canadian txoj kev saib xyuas kev saib xyuas tau teb rau 8m² diesel nchuav hauv ib lub tshuab cua daj cua dub 3% (khaws cia sab nraud thaum hmo ntuj). Cov npuas dej ntws tam sim ntawd, thiab nws 4.2-4.3 mn / m kis tau cov txau rau 15 feeb thiab ignited ib tug nyob ze snowbank.
5. Tus nqi ntawm kev qeeb qeeb xa: vim li cas nrawm teeb meem
Txhua thib ob ntawm kev ncua hauv kev tua hluav taws sai ntxiv kev puas tsuaj:
Lub sijhawm 1-feeb tuaj yeem cia 3m11 roj av nchuav loj hlob mus rau 8m² (4x thaj chaw).
Txias - cheeb tsam qeeb (thaws npaus) nce ib puag ncig ib puag ncig cov neeg tuaj yeem tuaj yeem nrhiav cov daus thiab ncav hauv cov daus hauv 5 feeb.
- Lub affff 3% series txiav cov kev pheej hmoo no: Cov neeg siv daim ntawv qhia 70% nrawm dua pib ua npuas dej, thiab 50% tsawg dua kev puas tsuaj los ntawm hluav taws sai.
- Lub AFFF 3% series tsis yog tso tawm hluav taws kub - nws tso lawv tawmkev yoov movCov. Los ntawm kev tshem tawm cov sijhawm, kev yooj yim, thiab ua haujlwm hauv txhua yam xwm txheej, nws hloov thaum muaj xwm ceev "rau hauv pawg tsis muaj kev cob qhia tshwj xeeb.
Cauj thaum nws suav - Afff 3% series nres hluav taws sai ua ntej lawv escalate.
