Cov tshuaj tiv thaiv thermite yog cov tshuaj tiv thaiv oxidation-txo qis zoo ib yam li qhov hluav taws kub ntawm cov hmoov dub. Cov tshuaj tiv thaiv yuav tsum muaj hlau oxide thiab roj. Cov roj hauv cov tshuaj tiv thaiv thermite koj tsim yog txhuas hauv cov ntawv ci. Koj cov hlau oxide yog hlau oxide, feem ntau hu ua xeb.
Cov hlau twg yog tsim los ntawm cov tshuaj tiv thaiv thermite?
Cov tshuaj tiv thaiv thermite siv aluminium hmoov thiab hlau (III) oxide. Thaum ignited, qhov sib tov reacts vigorously vim qhov sib txawv loj hauv reactivity ntawm txhuas thiab hlau. Cov cua kub uas ua rau hauv cov tshuaj tiv thaiv melts cov hlau tsim.
Yuav ua li cas cov khoom tsim tom kawg ntawm cov tshuaj tiv thaiv thermite?
tshuaj tiv thaiv
Fe2O3 + 2 Al → 2 Fe + Al 2 O. Cov khoom lag luam yogaluminium oxide, cov hlau hlau, thiab cov cua kub ntau. Cov reactants feem ntau yog hmoov thiab tov nrog ib tug binder kom cov khoom ruaj khov thiab tiv thaiv kev sib cais.
Thermite yog dab tsi?
Thermite yog ib qho pyrotechnic feem ntau muaj ntawm cov hmoov hlau thiab cov hlau oxide. Nws tsis yog feem ntau tawg, tab sis nws tsim kub heev nyob rau hauv ib qho chaw me me rau lub sij hawm luv luv. Piv txwv li, aluminium / hlau-oxide thermite kub yog siab li 4500 degrees F.
Cov hlau twg yog siv rau hauv cov thermitevuam?
Npe cov hlau uas nquag siv hauv Thermite Vuam txheej txheem? Teb: Aluminium hlau, Hauv thermite welding aluminium hmoov, yog siv nrog ferric oxide.
