Hluav taws yog qhov tshwm sim ntawm cov tshuaj tiv thaiv hu ua combustion . Nyob rau hauv ib tug tej yam taw tes nyob rau hauv lub combustion cov tshuaj tiv thaiv, hu ua ignition point, nplaim taws raug tsim. Cov nplaim hluav taws muaj feem ntau ntawm carbon dioxide, dej vapor, oxygen, thiab nitrogen.
Tsis tas li lo lus nug yog, dab tsi yog cov tshuaj tiv thaiv hluav taws kub tswj?
combustion , ib qho tshuaj tiv thaiv ntawm cov tshuaj, feem ntau suav nrog cov pa oxygen thiab feem ntau yog nrog los ntawm kev tsim cov cua sov thiab lub teeb nyob rau hauv daim ntawv ntawm nplaim taws.
Tom qab, lo lus nug yog, dab tsi yog cov tshuaj tua hluav taws hauv huab cua? Phosphorus yog pyrophoric tshuaj , txhais tau tias nws yuav spontaneously ignite nyob rau hauv huab cua.
Raws li, hluav taws kub tshuaj yog dab tsi?
A tshuaj tua hluav taws yog ib qho nplaim taws uas pib vim a tshuaj cov tshuaj tiv thaiv uas ignites ib qho khoom, kua, los yog roj tshuaj compound. Yuav kom tiv thaiv kom raug tshuaj tua hluav taws , Nws yog ib qho tseem ceeb kom nkag siab tias lawv pib thiab nyob li cas.
Qhov hluav taws kub tuaj qhov twg?
Feem ntau, hluav taws los ntawm cov tshuaj tiv thaiv ntawm cov pa oxygen hauv qhov chaw thiab qee yam roj (xws li ntoo lossis roj av, piv txwv li). Ntawm chav kawm, ntoo thiab roj av tsis spontaneously catch on hluav taws tsuas yog vim lawv nyob ib puag ncig ntawm oxygen.
