Lub affff 3% series tsis yog hluav taws kub suppressant {}} nws yog cov kev siv thev naus laus zis huab cua kev hem thawj. Nws cov qauv peb, txhua qhov ntsuas rau cov huab cua tshwj xeeb thiab kev ua haujlwm los ntawm kev nyuaj thiab ua kom pom tseeb tias kev ua npuas ncauj ua tiav qhov twg lwm cov npuas.
1. Huab Cua Womium Dominance: Los ntawm Arctic Frost rau qhov kub
Lub AFFF 3% series 'peb qhov sib txawv yog ua kom muaj zog nyob hauv ib puag ncig uas yuav ua npuas ncauj. Ntawm no yog li cas lawv cov kev txwv txhais lus rau tiag- ntiaj teb resilison resilisence:
| Qauv Parieter | Afff 3% (-1 degree) | Afff 3% (-16 Qib) | Afff 3% (-35 degree) |
|---|---|---|---|
| Khov taw tes | -1 degree | -16 Qib | -35 Degree |
| Cov nro | 16,2 mn / m | 17.3 mn / m | 18.7 mn / m |
| Kis cov coefficient | 6.2-6.4 mn / m | 3.5-3.8 mn / m | 4.2-4.3 mn / m |
| Kev nthuav dav | 8.3±1 | 6.6±1 | 7.6±1 |
| 25% lub sijhawm tawm | 2.9 (1 ± 20%) min | 2.5 (1 ± 20%) Min | 3.2 (1 ± 20%) min |
Arctic & Setartic Cheeb Tsam (AFFF 3% (-35 Degree))
Nrog -}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Txoj Kev Khov khov ua kom khov, tus qauv no yog mus-rau sab qaum teb Russia lossis Canadian Arctic. Nyob rau hauv 2024 roj field hluav taws hauv Alaska, uas kub siab plummeted rau -28 degree, afff 3% (-35 degree) tseem ua tau zoo. Nws muaj 7.6 ± 1 cov kev nthuav dav sib piv tau tsim ua npuas ple ntom nti uas yog cov roj ntsha ua npuas kom tau ruaj khov ntev kom tau ruaj khov rau hauv subzero cua.
Huab cua continental txias (afff 3% (-16 degree))
Rau cov cheeb tsam zoo li Mongolia lossis sab qaum teb Asmeskas nrog Winters xa mus rau -15 degree, cov qauv sib npaug ua khov ua thiab kev ceev ceev. Nyob rau hauv 2023 tshuaj nroj tsuag hluav taws kub hauv Minnesota, AFFF 3% (-16℃tau tso cai rau ua npuas dej ua ntej nws tso hluav taws ua ntej nws mus txog qhov chaw tso tsheb hlau luam.
Lub cev kub & sov aav (afff 3% (-1 degree))
Hauv cov huab cua dav dav (piv txwv li, central Europe, feem ntau Asmeskas cov xeev), qhov no variant maximizes ceev. Nws cov kev lag luam - ua rau 16.2 mn / m sab nro thiab 6.2-6.4 mn / m kis coeffient yam ua kom nws to "flash npog" roj hluav taws xob. Thaum lub sij hawm 2022 cov khoom siv hluav taws kub hauv lub teb chaws Yelemees, nws tua tau ib 200m² blaze hauv 2.5 feeb-40% nrawm dua li lub vev xaib yav dhau los.
2. Cov Hluav Taws Xob Hluav Taws Xob Yooj Yim: Los ntawm cov roj me me mus rau mega -} tank bazes
Lub affff 3% series tsis muaj txwv los ntawm hluav taws kub. Nws cov kev ntsuas ntsuas kom tau raws li kev hem thawj los ntawm kev lom zem me me rau kev lag luam - nplai infernos:
- -} nplai xau (piv txwv li, lub tsheb roj nchuav): AFFF 3% (-1 degree) 's℃expio (8.3 ± 1) thiab lub sijhawm nrawm (2.9 min) ua rau nws zoo tagnrho. Ib me ntsis mloog mus rau txoj kev ntev-1L tuaj yeem them rau 9.3l ntawm ua npuas ncauj, txaus rau lub tsheb roj tsheb nres hauv vib nas this. Cov chaw tua hluav taws hauv nroog thaj chaw cia siab rau qhov no rau kev teb sai.
- Nruab nrab - scale hluav taws (piv txwv li, Warehouse Solvent Cia): AFFF 3% ({- 16 degree) 'Degree)' Degree) 'Degree) thiab 2.5 min qhov dej ntws tawm ntawm no. Nyob rau hauv 2023 Warehouse hluav taws hauv Ontario, Canada, qhov twg 500 tus qauv ntawm cov npuaj teg ua npuas dej thaj chaw, tiv thaiv hluav taws kub los ntawm kis mus rau cov khoom lag luam nyob sib ze. Lub 3.5-3.8 mn / m sib kis coeffievievient pab tau txawm tias cov kev pab them nqi tsis xwm yeem, cov khib nyiab-strewn chaw.
- Loj -}} nplai tank hluav taws (piv txwv li, petrochemical cia): AFER 3% ({{5 5}} 35 Degree) 'Degree) thiab 3.2 min kua dej ntws tau rau Mega-tsheb hlau luam. Hauv ib qho 2024 Saudi Hluav Taws Hluav Taws Hluav Taws Hluav Taws Hluav Taws Hluav Taws Hluav Taws Xob Hluav Taws Xob, tus qauv no tswj kev ncaj ncees rau ntau tshaj 3 feeb, cia cov neeg ua haujlwm muaj xwm txheej ceev los xaiv cov kev cai lij choj kom tsim kho kom tau nyiaj theem nrab. Nws cov 4.2-4.3 mn / m sib kis coefficievieveient kom ua npuas ncauj dhau lub tank txoj kev nkhaus, sib khi ntawm cov nplaim taws.
3. Kev Tsim Kho: Vim li cas cov lus txhais lus rau tiag- ntiaj teb wins
Txhua qhov metric nyob rau hauv lub afff 3% yog tsim los daws cov hluav taws kub- kev sib ntaus sib tua:
- Nto nro & kis coefficient: Cov no hais yuam kev ntev npaum li cas ua npuas dej tuaj yeem "ntub tawm" thiab ntim cov roj chaw. Tsawg dua sab nro (zoo li afff 3% (-1 degree) 'txhais tau tias cov npuas kis tau sai dua, txiav cov pa oxygen ua ntej hluav taws tuaj yeem ua kom muaj zog.
- Kev nthuav dav: Ntau ua npuas dej ib lift ib npaug sib npaug npog cov kev faj, txo tus nqi siab xav tau thiab txo tus nqi. Afff 3% (-1 degree)'s 8.3 ± 1 sib piv yog cov qib siab hauv nws chav kawm.
- 25% lub sijhawm tawm: Qhov kev ntsuas ua npuas dej ruaj khov. Lub sijhawm ntev dua (zoo li AFFF 3% ({}}}}} {{5- Qhov tseem ceeb rau kev ua si sab nraum zoov lossis hluav taws kub loj.
4. Nqi - rau - Kev Tshaj Tawm Piv Txwv: Ntev} Lub Sij Hawm} Lub Sij Hawm} Lub Sij Hawm} Sijhawm Tshaj Kev Tshaj Tawm
Lub affff 3% series tsis yog hais txog kev tso hluav taws kub - nws yog hais txog xa Roi:
- Txee lub neej: Txhua tus qauv tswj kom muaj kev ua tau zoo txog 10 xyoo hauv cov thawv ntim khoom, deb tshaj li 5-7 lub neej ntawm cov ua npuas dej laus. Qhov no txo cov nqi tsheb kauj vab thiab cov nqi logistics.
- Cov Khoom Siv Tau Ntau: Cov 3% sib tov sib piv yog universal, ua haujlwm nrog cov ua npuas dej cov ntsiab lus, saib xyuas cov neeg saib xyuas, thiab cov tshuab ua haujlwm. Tsis muaj kev xav tau cov khoom siv hloov khoom kim heev, ua rau nws cov nyiaj txiag - Tus phooj ywg xaiv rau ob qho chaw muaj kev lag luam thiab cov chaw tua hluav taws.
- Txo hauv qab: Kev nrawm nrawm (ua haujlwm los ntawm cov coefficients qis cov coefficients) txhais tau tias hluav taws kub muaj nrawm dua, txo kev ua haujlwm sai sai. Rau cov nroj tsuag petrochemical, qhov no tuaj yeem txhais rau ntau lab nyob hauv kev cawm cov nqi ntau lawm ib qho xwm txheej.
- Lub affff 3% series ua pov thawj tias hluav taws kub tsis yog tsuas yog hais txog kev daws teeb meem uas hloov kho huab cua, hluav taws xob daws teeb meem. Nrog nws cov qauv tsis muaj tseeb thiab qhov tseeb {{{{{{3} Ntiaj teb cov pov thawj, nws yog qhov raug rau cov chav kawm b Hluav taws los ntawm cov feem ntau xav tau ib puag ncig.
Engineered rau qhov kawg, muaj pov thawj hauv txhua qhov hluav taws kub - af af afff 3% series teeb tsa cov qauv kua roj supression.
