Cov nplaim hluav taws xob ntawm cov hlau. Lub hauv paus ntsiab lus yooj yim ntawm cov nplaim hluav taws xob yog cov hlau ntsev tso tawm lub zog tsim los ntawm kev sib xyaw ua ke hauv daim ntawv ntawm lub teeb. Thaum ib feem ntawm cov ntsev raug hlawv, cov hluav taws xob sab nraum lub hauv paus ntawm cov hlau nqus lub zog thiab dhia los ntawm qis orbital mus rau qhov siab dua orbital. Cov txheej txheem no tsis ruaj khov thiab thim rov qab. Thaum cov electrons rov qab los ntawm qhov siab dua orbital, lub zog ntau dhau raug tso tawm dua li lub teeb. Thiab cov ntsev sib txawv ntawm cov ntsev muab tawm qhov sib txawv wavelengths ntawm lub teeb, uas yog reflected nyob rau hauv txawv xim rau qhov muag liab qab. Yog li ntawd, los ntawm kev ntxiv cov ntsev sib txawv rau cov foob pob hluav taws, lawv yuav tshwm sim xim txawv thaum lawv hlawv.
Cov foob pob hluav taws liab feem ntau ntxiv strontium ntsev thiab calcium ntsev; Cov foob pob hluav taws daj feem ntau ntxiv sodium ntsev; Potassium ntsev thiab lithium ntsev feem ntau yog ntxiv rau cov pob zeb liab; Cov foob pob hluav taws ntsuab feem ntau ntxiv tooj liab ntsev thiab barium ntsev. Cov nplaim xim cov tshuaj tiv thaiv ntawm cov ntsev sib txawv, ua ke nrog lub teeb dawb ci ntsa iab thaum lub teeb ci ntsa iab aluminium hmoov thiab magnesium hmoov kub hnyiab, kom peb cov foob pob hluav taws thaum kawg qhia cov xim ci ntsa iab.
Cov foob pob hluav taws ua los ntawm dab tsi?
Cov tshuaj muaj pes tsawg leeg ntawm cov foob pob hluav taws ua tiav yog tsim los ntawm oxidizer, roj, xim tus neeg sawv cev thiab tus neeg ua kom pom kev zoo. Oxidant plays lub luag hauj lwm ntawm combustion pab, oxidation thiab tshav kub tso tawm, feem ntau yog nitrate thiab chlorate, thiab lwm yam. Combustible cov ntaub ntawv mas muaj xws li carbon hmoov, sulfur, thiab lwm yam, uas mas plays lub luag hauj lwm ntawm combustion thiab lub zog mov; Tus neeg saib xyuas kev txhim kho xim yog tsim los ntawm qee cov hlau ntsev xws li sodium ntsev, tooj liab ntsev, barium ntsev, thiab lwm yam, kuj yog lub hauv paus tseem ceeb ntawm cov nplaim taws xim; Lub hom phiaj ntawm tus neeg sawv cev ci ntsa iab yog ua kom cov foob pob hluav taws ntau dua thiab zoo nkauj, feem ntau yog siv magnesium hmoov thiab txhuas hmoov thaum hlawv lub teeb dawb.
