Daim duab peb sab qhia txog peb yam uas hluav taws yuav tsum tau ignite: kub, roj, thiab ib tug oxidizing tus neeg sawv cev (feem ntau. oxygen ).
Tsis tas li lo lus nug yog, qhov hluav taws kub tsim li cas?
Tshuaj tiv thaiv nyob rau hauv cov txheej txheem combustion Thaum lub sij hawm cov tshuaj tiv thaiv uas tsim hluav taws , roj yog rhuab mus rau xws li ib tug npaum li cas (yog hais tias tsis yog ib tug gas) nws tso gases los ntawm nws nto. Heated molecules yog loosened, txav sib nrug mus daim ntawv ib gas. Cov roj molecules ua ke nrog cov pa oxygen hauv huab cua ua rau hlawv.
Ib tug kuj nug, 5 theem ntawm hluav taws yog dab tsi? Los ntawm cov qauv feem ntau suav nrog International Hluav taws Lub Koom Haum Pabcuam Kev Kawm (IFSTA) muaj 4 theem ntawm a hluav taws . Cov no theem yog incipient, loj hlob, tag nrho tsim, thiab lwj. Cov hauv qab no yog ib qho luv luv ntawm txhua tus theem.
chemical formula rau hluav taws yog dab tsi?
Lub combustion ntawm methane yog sawv cev los ntawm cov kev sib npaug : CH4 + 2 O ib2 → CO2 + 2 H2O.
Puas yog hluav taws kub?
Hluav taws yog tsim los ntawm ntau yam sib txawv, soit tsis yog ib qho keeb . Rau feem ntau, hluav taws yog amixture ntawm kub gases. Cov nplaim taws yog qhov tshwm sim ntawm cov tshuaj tiv thaiv tshuaj, feem ntau ntawm cov pa oxygen hauv huab cua thiab roj, xws li ntoo lossis propane.
