Thaum ntsib kev phom sij tua hluav taws, xaiv cov cuab yeej siv hluav taws kom raug yog qhov tseem ceeb. Raws li ib qho ntawm cov khoom siv hluav taws kub tshaj plaws, cov hmoov dej qhuav hluav taws xob tau siv dav hauv ntau hom hluav taws kub vim lawv cov kev ua haujlwm siab thiab versatility. Txawm hais tias nyob hauv tsev, chaw haujlwm, lossis cov chaw muaj cov hmoov cua qhuav, cov hmoov hluav taws xob tua hluav taws tuaj yeem ua lub luag haujlwm tseem ceeb hauv lub sijhawm tseem ceeb. Yog li, dab tsi yog cov hmoov qhuav dej tua hluav taws? Dab tsi ntawm cov hluav taws yog lawv haum rau?
Dab tsi yog hmoov yas tua hluav taws?
Cov Hmoov Qhuav Tua Hluav Taws TsoCov khoom siv hluav taws kub uas tau pom hluav taws xob hluav taws xob tau siv los tawm tsam ntau hom hluav taws. Lawv tus thawj coj tua hluav taws yog cov tshuaj txhuam hniav kom qhuav, muaj ntau yam los ntawm sodium bicarbonate, ammon phosphate, lossis lwm yam inorganic ntsev-blued fwj. Cov hmoov no sai sai suppresses nplaim taws thiab tiv thaiv hluav taws re-ignition. Raws li cov tshuaj muaj tshuaj lom neeg thiab cov ntawv thov, cov hmoov qhuav extinguishers poob rau hauv peb pawg:
●Chav Kawm BC (Txuj Ci): Tsim rau cov kua roj (piv txwv li, roj av) thiab roj hluav taws;
●Chav Kawm ABC (muaj txiaj ntsig zoo): Pib tawm tsam cov khoom sib txuas, kua, thiab roj av;
● Cov tshuaj tshwj xeeb qhuav: tsim rau cov hluav taws hlau (piv txwv li, poov tshuaj [k], sodium [na], magnesium [mg] siv cov hmoov hlau tshwj xeeb.

Cov Cheebtsam Ntawm Cov Hmoov Qhuav Yas Tua Hluav Taws Xob
Cov ntsiab lus tseem ceeb ntawm cov hmoov nplej qhuav cov tshuaj tua hluav taws, cov roj av cov roj av, cov hlab ntsha siab, thiab cov tshuab coj tawm. Cov ntsiab lus tseem ceeb muaj cov ncauj lus kom ntxaws raws li nram no:
Hluav Taws Kub Kub:
●Sodium bicarbonate (Nahcox): Undergoes thermal decomposition kom tso tawm co₂, tsim cov pa oxygen-depleting nyhuv.
●Ammonium dihydrogen phosphate (Nh₄h Thenphate (Nh₄hshpo₄): Tsim los rau chav kawm ABC Hluav Taws, inhibits saw kev sib tw tiv thaiv ntawm endothermic decomposition.
●Cov neeg ua haujlwm tshwj xeeb (piv txwv li, poov tshuaj chloride, sodium sulfate): phiaj d) nrog lub ntsej muag siab thiab txhim kho Entermic muaj peev xwm.
Cov khoom siv roj:
●Nitrogen lossis qhuav compressed cua: tswj cov txheej txheem siab ntawm 1.2-1.8 MPA los xyuas kom meej.
●Ya dej noo-tswj roj: tiv thaiv cov hmoov clumping los ntawm kev ua kom nruj raws cov txheej txheem.
Ntxiv:
●Hydrophobic tus sawv cev (piv txwv li, roj silicone): Txhim kho cov dej noo): Txhim kho cov dej noo tsis kam rau lub sij hawm ntev kev ruaj khov.
●Anti-Cakake Ceg Txheem (piv txwv li, Mica hmoov, silicates): tiv thaiv pcicle sib nraus hauv siab.
●Ntws EnhanceCers: Txhim kho cov hmoov sib cais thaum tso tawm rau kev them nyiaj uas muaj teeb meem.
Los ntawm cov qauv tshwj xeeb thiab kev ua tiav, cov tshuaj lom neeg qhuav tiv thaiv kev nqus dej noo ntawm cov pa tawm thiab ntab hluav taws xob.
Yuav ua li cas lub txiv qhuav tws tua hluav taws
Cov Hmoov Qhuav Yas Tua Hluav Taws Xob Terminers Terminate Commusion Combusion los dhau ntawm ob lub cev nqaij-tshuaj tua neeg:
1. Tshuaj tsis muaj kev cuam tshuam
Hmoov decompposition nyob rau hauv nplaim taws tso tawm dawb radical-scavenging cov neeg sawv cev (piv txwv li nh₄⁺ los ntawm ammonium phosphate), cuam tshuam kev sib txuam cov tshuaj tiv thaiv kab ke;
2. Lub cev kev sib tsoo
Hmoov huab los tsim cov pa oxygen-thaiv ntawm cov roj av ntawm cov roj deg;
3. Annillary Cua Txias
Endothermic decomposition muab cov thermal buffering.
Lawv cov chaw tsis ua haujlwm thiab ntau chav tua hluav taws (suav nrog hluav taws kub hauv hluav taws xob rau ib NFPA 70E) kom muaj kev nyab xeeb hluav taws xob.
Hmoov qhuav dej tua hluav taws siv rau
Hmoov tej hmoov tua hluav taws-extinguishers yog thoob ntiaj teb deplateed thoob plaws cov chav tua hluav taws vim lawv cov kev phom sij ntau:
●Chav Kawm A: Cov khib nyiab ua ke (ntoo, ntawv, textiles) - hais los ntawm ntau hom phiaj (ABC chav kawm) cov neeg sawv cev;
●Chav Kawm B: Cov kua dej ua kua (roj av, ethanol) - suppressed ntawm oxygen tsis zoo;
●Chav kawm c: compastible gases (LPG, Methane) - neutralized los ntawm nplaim taws tshaj tawm kev cuam tshuam;
●Hluav Taws Xob Hluav Taws Xob: Muaj kev nyab xeeb rau cov khoom sib zog (tsawg dua lossis sib npaug rau 1000v rau ib NFPA 70) ntawm cov hmoov tsis sib xws (zam cov chaw nres tsheb siab).
Lawv cov versatility ua kom cov txheej txheem teeb tsa hauv cov chaw nyob, cov chaw lag luam tsheb, ua haujlwm nrog OSHA 1910.157 chaw ua haujlwm kom ruaj ntseg.
Hmoov hmoov hluav taws xob tua hluav taws tsis siv rau
Thaum lub sij hawm veratile, qhuav hmoov tua hluav taws siv hluav taws xob tsis pom zoo hauv cov xwm txheej no:
●Precision Electronics: Residual Hmoov Infiltrates Circuit Court Corrcuitry, Posing Post-Tawm Kev Ruaj Ntseg \/ Kev Cuam Tshuam;
