Ua npuas ncauj ua npuas ntev?
Foinbo hluav taws ua npuas ncauj ua npuas ncauj ua npuas ncauj sib xyaw nrog dej los ua kom tiav chav kawm a (tawv) thiab b (kua), txias, thiab vapor supression. Nws yog lub siab (1-6% dilution) nrog surfactants thiab stabilizers, muaj kev txuag nyiaj) thiab siv sijhawm ntau, thiab lub neej ntev. Nws yog siv hauv kev lag luam, cov chaw nres tsheb nkev, chaw khaws khoom, chaw tsim khoom, thiab chaw pej xeem. Txhawm rau siv, dilute nrog ib qho kev sib cais, xa cov tswv yim, thiab khaws cov cuab yeej siv.
Kev piav qhia dav dav
Foinbo hluav taws ua npuas ncauj ua npuas ncauj yog cov khoom siv ua kom haum nrog cov dej ua npuas dej rau chav kawm (tawv) thiab ua kua b (tawg). Tsim nrog surfactants, stabilizers, thiab nplaim taws (1-6% sib zog) thiab versatility ratiet, thiab versatility, versatility, versatility nyob rau hauv cov tshuab, thiab lub neej ntev. Qhov tseem ceeb sib txawv muaj nyob nruab nrab ntawm chav kawm A (0.1-1% kev sib tw) ua npuas ncauj, cov khoom lag luam hauv tsev kawm ntawv (chaw dav hlau), chaw dav dav, thiab chaw dav dav. Txhawm rau siv, xaiv hom txoj cai / piv, dilute nrog ib qho kev ua npuas ncauj, thiab tswj hwm cov khoom siv hauv chav kawm, Nws lub peev xwm los daws ob qho hluav taws thiab cov hluav taws ua kua, ua khub nrog kev txij nkawm qis, ua rau nws lub cev tseem ceeb hauv hluav taws kub.
Cov txiaj ntsig zoo ntawm Foinbo ua npuas npuas tsom kom zoo
Multi -}}} Kev Txom Nyem OXperforms Ib Leeg {{}}}}}}}}}}}. Tsis zoo li cov dej (uas tsuas yog txias) lossis siv tshuaj kom qhuav (ua npuas ncauj sib xyaw ua ke), ua npuas dej sib xyaw), cua txias (tiv thaiv cov nplaim hluav taws xob). Qhov ntau {{{{{}} txheej txheem qhia yog qhov tseem ceeb tshaj plaws rau chav kawm bires (piv txwv li dej ib leeg kis cov roj thiab exacerbates lub blaze. Rau chav kawm ib qho hluav taws kub (piv txwv li, cov ntawv, ua npuas ncauj nkag mus rau cov ntaub ntawv ntxeem tau rau kom muaj kev pheej hmoo tob tob txog 70% piv rau dej.
Motenrated misagen cov nqi xa nqi thiab kev cia nyiaj. Ua npuas ncauj mloog yog cov kev sib piv zoo heev (1-6% dilution piv), lub ntsiab lus 1-100 litres ntawm cov tshuaj ua npuas ncauj. Qhov no yuav tsum muaj qhov chaw cia: Lub nruas xyoo 200l ntawm cov khoom ua npuas dej ua npuas dej Nws kuj yog cov nqi tsheb thauj qis qis, xav tau tsawg dua los muab hluav taws kub loj hluav taws xob.
Versatility thiab sib haum tau txais kev siv tau siv tau. Foinbo vaj ua npuas ncauj ua haujlwm nrog txhua tus qauv ua npuas dej {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} thiab muaj ntau yam dej qab zib thiab dej qab zib). Nws muaj nyob rau hauv cov qauv rau qee qhov chaw: aqueous zaj duab xis {}}}}}}}}}}}}}} {} {}} Cov npuas dej hnyav, thiab ua npuas ncauj rau cov khoom siv roj. Cov versatility tshem tawm qhov yuav tsum tau npaj ntau qhov tshwj xeeb suppressants, simpivering cov khoom muag kev tswj hwm.
Ntev txee lub neej thiab kev saib xyuas qis txo qis kev ua haujlwm nra. Thaum muab ntim rau hauv lub kaw, ntim txias, foinbo lub npaus ua npuas ncauj mloog tau muaj lub neej sib xyaw ua npuas (uas yog ua npuas dej ua ntej (uas tas sij hawm hauv 6-12 lub hlis). Nws yuav tsum tsis muaj kev sim ua tsis tu ncua Tshaj Kev Tshawb Xyuas Kev Tshawb Fawb Xyoo (Kev kuaj xyuas rau kev tshem tawm txhua xyoo lossis kev ua kom qhuav), tsis zoo li cov tshuaj txhuam kom qhuav. Qhov kev saib xyuas no ua kom pom tseeb yog npaj siab rau kev siv thaum muaj xwm txheej ceev, txo qis nqi thiab cov nqi ua haujlwm.
Dab tsi yog qhov txawv ntawm chav kawm A thiab B Ua Npuas Ncauj?
Chav kawm A thiab B ua npuas ncauj - ob qho no muaj los ntawm foinbo- Kuv cov hluav taws xob sib txawv, ua kom haum rau lawv cov hom hluav taws.
Kev Tsim Qauvdag nyob rau hauv lawv cov tseem ceeb thiab dilution sib piv. Chav kawm ua npuas ncauj yog tsim rau cov khoom siv roj (ntoo, ntaub, ntim cov dej kom nruj thiab ua npuas ncauj kom sib kis thiab nkag mus rau cov ntaub ntawv ntxig. Nws feem ntau siv qis dua cov dilution Piv (0.1-1%) {}} Feem ntau xav tau vim tias nws lub luag haujlwm tseem ceeb yog txhawm rau txhim kho cov dej txias thiab nkag mus, tsis yog ua ib lub ntsej muag tuab. Chav Kawm B Ua npuas ncauj kom mloog zoo, los ntawm kev sib piv, roj av, cov roj hmab {9} Nws yuav tsum muaj kev sib zog ntau dua (3-6%) kom ntseeg tau tias cov npuas dej yog tuab txaus los thaiv cov pa oxygen thiab tsis kam los ntawm cov pa roj.
Hluav Taws Kub Hluav Taws Xobtxawv raws li lawv lub hom phiaj roj. Chav Kawm Ua Npuas Ncauj Ua Haujlwm los ntawm "Dej Li Dej": surfactants tso cai rau cov dej hiav txwv thiab saib rau hauv cov kab nrib pleb, cua txias hluav taws los sab hauv. Nws tseem ua cov txheej txheem ua npuas dej nyias nyias uas tiv thaiv rov - ign ign}} ignition los ntawm mus txog kub hluav taws xob. Piv txwv li, ntawm ib lub hlawv ntoo ntoo, chav ua npuas nyob rau cov tsiaj ua npuas dej kom ua npuas dej nres oxygen los ntawm reigning nto embers. Chav kawm b ua npuas dej, li cas los xij, ua rau "Vapor supression thiab flathering rau cov kua dej tuab dhau, tiv thaiv cov oxygen": nws tsis tuaj yeem tiv toj cov roj thiab ntaiv cov pa tawm. Qee chav kawm b foams (zoo li riam phom nyias tom qab ua kua rau ntawm cov kua ua kua, ntxiv txhim kho vapor thaiv thiab kis tau sai kom npog cov roj loj.
Daim ntawv thov thiab kev ua tau zoo sib txawvyog qhov tseem ceeb rau kev siv tau zoo. Chav Kawm Ua Npuas Ncauj yog siv nrog Txheem Hluav Taws Xob Hoses thiab Nozzles, feem ntau hauv cov chaw txau kom ua tau cov khoom hluav taws xob ntau dua (piv txwv li cov hluav taws xob, hluav taws kub). Nws yog qhov tsis tshua tshee thiab tawg sai sai dua kev kawm b npaus, raws li nws tsis tas yuav tawm tsam cov roj vapors. Chav Kawm B Ua npuas ncauj yuav tsum muaj cov kev xa khoom tshwj xeeb (piv txwv li, ua npuas ncauj tsis muaj zog, cov lus tshaj tawm) kom ntseeg tau tias kev tsim kom zoo thiab ua npuas. Nws yog denser thiab ntau ruaj khov, tswj nws cov qauv rau 15-30 feeb ntawm cov kua dej {}} qhov tseem ceeb rau muaj cov roj loj. Siv cov kev pheej hmoo tsis ncaj ncees lawm tsis ua haujlwm: Chav Ua Npuas Ncauj yuav tsis ua cov dej ua kua, thaum chav kawm b npuas dej txaus rau cov khoom siv, cov khoom siv nyiaj so thiab ncua kev tsuj.
Qhov twg siv ua npuas ua npuas?
Cov Chaw Muaj Cov Vaj Tseyog cov neeg siv thawj, nrog cov qauv tshwj xeeb rau cov phom sij sib txawv. Cov roj ua kom zoo, cov nroj tsuag tshuaj, thiab petrochemical cia Yards cia rau hauv chav kawm B Feam (piv txwv li cov roj crude, cov kuab tshuaj, lossis roj nchuav. Cov chaw no feem ntau ua rau muaj kev xav nrog cov tshuab roj (lub zais zis, saib xyuas) kom npog cov chaw tso tsheb loj lossis ua cov chav ua haujlwm loj. Kev tsim khoom lag luam nroj tsuag (xws li, electronics) Siv chav kawm ua npuas dej, lossis ntaub ntawv ntim ntoo, ntim khoom siv hluav taws xob cuam tshuam nrog cov kab thiab cov khoom lag luam ntim ntau lawm thiab cov khoom muag.
Kev Lag Luam Roj -} ionsegUa raws li kev ua npuas boam rau kev nyab xeeb ua raws. Cov chaw nres tsheb roj, roj chaw nkaum, thiab aviation Fuenting chaw nres tsheb Banks banks (200-500l) ua ke nrog portable foam ua npuas nozzles. It is used to suppress spills from fuel pumps, underground tank leaks, or aircraft fueling accidents-its rapid-spreading properties critical for containing small spills before they ignite. Piv txwv li, cov aviamia teb siv 3% afff tsom mus rau tam sim ntawd npog dav hlau roj nchuav ntawm tarmacs, tiv thaiv vapor ignition.
Cov chaw khaws khoom thiab cov chaw cia khoomSiv ob chav kawm A thiab B Ua Npuas Ncauj raws li cov khoom. Warehouses khaws cov khoom ruaj khov (xws li, daim ntawv) xa cov chav ua npuas dej {}}}}-} zaum sib xyaw. Cov khoom siv ua kua roj (piv txwv li, cov xim pleev xim, lubricants) siv chav kawm b ua npuas, feem ntau ua ke nrog cov kais tsuag dej los yog hluav taws kub.
Tubrog Nkoj thiab Tsheb Thauj Mus LosKev teeb tsa cia siab rau ua npuas ncauj mloog rau ntawm - board muaj kev nyab xeeb. Cov nkoj, cov roj av nres roj av, thiab chaw nres nkoj terminals siv ntsev ntsev rau kev kawm beep (fluoroprotein) mus rau chav roj lossis cov khoom thauj khoom. Qhov kev xav tsis thoob los tiv thaiv Saladwater degradation, kom ntseeg tau ua npuas zoo zoo txawm nyob hauv ib puag ncig marine. Cov chaw tua hluav taws kuj tseem siv cov khoom siv hluav taws xob ua kom zoo nkauj rau cov roj av hauv chav (los ntawm cov roj av muaj hluav taws xob (chav kawm ib qho, los ntawm cov nyom thiab ntoo).
Tuam tsev thiab pej xeem siv ua npuas kom zoo rau cov kev pheej hmoo. Tsev kho mob, tsev kawm qib siab, thiab chaw nres tsheb chav kawm ua npuas dej hauv tsev qiv ntawv (cov ntawv sau), lossis cov khoom ntoo). Tshav dav hlau Siv cov chav kawm b foof hauv Hangars los tiv thaiv cov dav hlau hluav taws xob siv hluav taws xob, thaum lub khw muag khoom hauv chaw nres tsheb kom txo qis cov tsheb txia.
