Chav Kawm B Fuels Vary wildly -}}}}} {{2 {2. Tsoos ua npuas ncauj feem ntau tsuas yog ua haujlwm rau ib qho roj hom, yuam cov neeg siv khoom lag luam ntau cov khoom. Lub AFFF 3% series daws qhov no nrog roj - Cov qauv ntsuas: Txhua tus qauv yog txhawm rau txhawm rau txhawm rau txhim kho kev ua npuas.
1. Cov tsis muaj tseeb: roj -}} adved specs
Txhua qhov metric ntawm Afff 3% yog ntsuas kom phim li cas cov roj sib txawv hlawv, ntws, thiab sib cuam tshuam nrog ua npuas ncauj:
| Qauv Parieter | Afff 3% (-1 degree) | Afff 3% (-16 Qib) | Afff 3% (-35 degree) | Tus tseem ceeb Rev Admin |
|---|---|---|---|---|
| Cov nro | 16,2 mn / m (qis) | 17.3 mn / m (sib npaug) | 18.7 mn / m (ntom) | Tsawg=o} outspaces roj av; balanced=tiv cov kuab tshuaj |
| Kis cov coefficient | 6.2-6.4 mn / m (nrawm) | 3.5-3,8 mn / m (nplaum) | 4.2-4.3 mn / m (khov kho) | Cast=xob rov qab cov roj ntws; nplaum =} clings rau cov kuab tshuaj |
| Kev nthuav dav | 8.3 ± 1 (siab) | 6.6 ± 1 (Nruab Nrab) | 7.6 ± 1 (Nruab Nrab Nruab Nrab- ntom) | High =} dav kev tiv thaiv rau nchuav; dense=tiv thaiv tshav kub los ntawm cov roj |
| 25% lub sijhawm tawm | 2.9 (1 ± 20%) min | 2.5 (1 ± 20%) Min | 3.2 (1 ± 20%) min | Qeeb=txias cov roj tuab; nruab nrab =} Tsis txhob muaj kuab heev re-} ignition |
2. Rau lub teeb hydrocarbons (roj av, diesel, roj hlau)
Cov roj no tsis tshua muaj - viscosity, ntws nrawm, thiab dav} ntev yuav tsum muaj spills ua ntej lawv kis tau.
Zoo tshaj plaws haum: afff 3% (-1 degree)Nws 16.2 mn / m li mension cia ua npuas ncauj sib tw ua ntej ntawm ntws roj. Ib qho chaw nres tsheb Fabkis txoj qauv siv cov qauv no los lis 8 feeb sib kis tau ntawm 0.5m sib kis tau: Lub 8.3 ± 1 kev nthuav dav sib piv tau hais txog 103-93l ntawm thaj chaw, yog li cov neeg ua haujlwm tsis tas yuav tsum rov qab ua npuas ncauj (22 MNGE
3. Rau Polar cov kuab tshuaj (ethanol, acetone, methanol)
Cov kuab tshuaj sib xyaw nrog dej, tawg cov khaub ncaws ua npuas dej. Ua npuas ncauj ntawm no yuav tsum tau tawm tsam kev sib cais thiab tuav mus rau cov roj deg.
Qhov Zoo Tshaj: AFFF 3% (-16 Qib)Nws cov kev sib tw ntawm thaj chaw nruj (17.3 mn / m) thiab "nplaum" kis coefficient (3.5-3.8 mn / m) tiv thaiv cov kuab tshuaj los ntawm kev ua npuas ncauj. Ib qho kev siv tshuaj German German siv cov qauv no rau ib daim pam vov hauv qab 30 feeb, xav tau 3 re- kev siv.
4. Rau siab - Voscosity fuels (cov roj muaj zog, cov roj roj hnyav, roj)
Tuab fuels hlawv kub (300-500 degree) thiab tsis ntws - ua npuas}} Npuas}} ua npuas} Xav tau cov cua sov thiab qeeb qeeb kom khaws cov dej noo txias.
- Zoo Tshaj: AFff 3% (-35 degree) (khaub thuas) / afff 3% (-16 degree) (temperate)
- Cheeb tsam txias: Ib qho Alaskan Roj Teb siv afff 3% (-35 degree) rau 20m² hnyav roj roj hluav taws (-25 degree). Nws 7,6 ± 1 cov kev nthuav tawm ntom nti uas tiv thaiv cua, thiab lub sijhawm 3.2 feeb txaus kom txias cov roj rau 180℃(hauv qab flash point).
- Cov Cheeb Tsam Temperate: Teb Chaws Asmeskas Auto Kho Kom Zoo siab rau Afff 3% (- 16 degree) rau lub cev muaj zog roj nchuav. Qhov nruab nrab ceev (6.6 ± 1) clung kom tuab roj, thiab {} Faj Furpage ua npuas dej (1.8-feeb kua), uas xav tau ib lub tshuaj tsuag thib ob.
5. Tus nqi: Ib Series, Txhua tus roj
Lub affff 3% series tshem tawm qhov yuav tsum tau npaj ntau cov npuas dej rau cov roj sib txawv:
- Kev thauj khoom ntawm cov chaw thauj khoom roj av (cov tsheb thauj khoom), acetone (tsev muag khoom), thiab kev txij nkawm) siv tsuas yog ob tus qauv {{}}} Txiav cov khoom lag luam los ntawm 60%.
- Lub chaw sam roj tsheb txuag tau $ 1,200 / xyoo los ntawm ditching "kuab- ua npuas ncauj thiab siv afill 3% (-1 degree) rau txhua yam nchuav.
Lub AFFF 3% series tsis yog sib ntaus sib tua B Fires - nws hais lus rau txhua tus roj. Los ntawm kev sib txuam nrog cov roj teeb, nws xa yooj yim, txhim khu kev qha sauv rau txhua chav kawm b chav kawm.
Ib ua npuas dej, txhua tus fuels - Afff 3% Series haum koj cov hluav taws kub hnyiab li cas.
