Teb: Cov tshuaj tiv thaiv ntawm hlau (III) oxide (Fe203) thiab txhuas ua rau cov cua sov ntau. Nws yog hu ua thermit reaction. Qhov kev tshem tawm cov tshuaj tiv thaiv no yog siv los koom nrog kev tsheb ciav hlau lossis cov tshuab tawg. Lub tshav kub uas muab tawm hauv cov tshuaj tiv thaiv melts hlau tsim.
Koj txhais li cas los ntawm cov tshuaj tiv thaiv thermite?
Cov tshuaj tiv thaiv thermite yog lub npe dav rau ib qho exothermic (heat-tso tawm) cov tshuaj tiv thaiv ntawm ferrous oxides thiab txhuas (feem ntau hauv cov hmoov hmoov). Qhov sib xyaw ntawm txhuas thiab hlau oxide, tseem hu ua thermite, paub txog nws lub peev xwm los tsim cov cua sov thaum combustion.
Cov tshuaj tiv thaiv thermite yog dab tsi yog nws daim ntawv thov chav kawm 10?
Teb: Cov tshuaj tiv thaiv thermite yog cov tshuaj tiv thaiv exothermic ntawm cov hlau thiab hlau oxidePiv txwv li cov tshuaj tiv thaiv ntawm txhuas nrog cov hlau oxides, qhov twg txhuas ua raws li tus neeg sawv cev txo. Cov txhuas txo cov hlau oxide feem ntau yog hlau (lll) oxide los tsim ferrous thiab txhuas oxide.
txheej txheem thermite yog dab tsi qhov twg cov txheej txheem no siv Chav Kawm 10?
Nws tseem yog feem ntau hu ua Goldschmidt thermite txheej txheem lossis aluminothermy. -Cov tshuaj tiv thaiv ua kom muaj cua sov ntau uas txaus kom ncav cuag qhov kub ntawm li 3500oC. Cov hlau yog li tau txais yog nyob rau hauv lub xeev molten. -Cov txheej txheem no yog siv nyob rau hauv vuam ntawm railway lem, hnyav machinery, thiab lwm yam
Cov tshuaj tiv thaiv thermite yog dab tsi sau nws daim ntawv thov?
Kev siv cov txheej txheem thermite: 1) Cov tshuaj tiv thaiv ntawm Iron Oxide (Fe 2 O 3) nrog txhuas yog siv los koom nrog railings ntawm railway lem los yog mus koom lub tshuab tawg. 2) Nws kuj tseem siv tau los koom nrog cov khoom siv hlau tawg hauv tsev.
