Kev txhim kho ntawm cov txheej txheem tiv thaiv ib puag ncig thiab ntxiv cov ntsiab lus thev naus laus zis yog lub ntsiab lus tsis tu ncua ntawm kev tshawb fawb ntawm pyrotechnics, kom cov hom pyrotechnics yog brewing. Lub pyrotechnics ignited thiab ya mus siab thiab tawg, yog li cov nyhuv yuav zoo. Yog li ntawd, cov foob pob hluav taws muaj phom ntau dhau ntawm rab phom ntev rau kev tua thiab rab phom. Piv txwv li, tom qab tua tawm 20-ntev-txoj kab uas hla lub foob pob hluav taws, nws yuav tsum nce mus txog qhov siab ntawm thaj tsam 200 meters ua ntej nws tawg, ua rau peb txaus siab rau cov hnub qub muaj xim zoo nkauj. Lub vojvoog npog los ntawm cov hnub qub tuaj yeem yog 80 metres.
Ua ntsuas' t ntsuas lub hnub qub, lawv qhov ntsuas kub tsis qis. Thaum ci ntsa iab, lawv qhov kub yuav dhau 1000 ℃! Nws yog nyob rau ntawm qhov ntsuas kub zoo uas ntau yam khoom siv hlau tshwj xeeb uas muaj qhov hluav taws kub tuaj yeem nqus lub zog ntawm kev txaus siab thiab tshaj tawm qhov ci ntsa iab. Nov yog cov nplaim hluav taws tau tham ntau zaus hauv tsev kawm theem nrab. Nws yog qhov tseeb vim tias cov hlau atoms sib txawv tuaj yeem tawm cov xim sib txawv ntawm lub teeb thaum kub, peb tuaj yeem pom lub foob pob hluav taws ntawm cov xim sib txawv.
Txawm li cas los xij, nplaim hluav taws xob muaj qhov tiv thaiv qhov tsis txaus, uas yog, qhov kub thiab txias feem ntau xav tau. Yog li, peb pom me ntsis ntawm cov hluav taws kub hauv hluav taws qhia, qhov kub kub yog qhov siab heev. Feem ntau hauv cov txheej txheem, peb siv cov hlau sib txuas kom ncav cuag cov cua kub, xws li txhuas, magnesium, thiab lwm yam. Txawm hais tias qhov pyrotechnic residue poob rau hauv av, qhov kub hauv tsev tuaj yeem ncav cuag 300 ℃, nws tsis yog" xwb;" kub me ntsis ;. Yog li, nws yog qhov tseem ceeb heev uas yuav tau tswj hwm kev cuam tshuam ib ncua kev nyab xeeb.
