NITRIC ACID (CAS # 52583-42-3) qhia
Hauv kev lag luam kev tsim khoom, nitric acid plays lub luag haujlwm tseem ceeb. Nws yog cov khoom tseem ceeb hauv kev tsim cov tshuaj chiv, tshwj xeeb tshaj yog ammonium nitrate, uas yog siv dav hauv kev ua liaj ua teb los muab cov nitrogen tseem ceeb rau cov qoob loo kom vam meej thiab pab txhawb lub ntiaj teb cov zaub mov sau. Hauv kev lag luam hlau, nitric acid feem ntau yog siv rau hauv kev kho hlau nto, los ntawm corrosion, passivation thiab lwm yam txheej txheem, tshem tawm impurities thiab xeb ntawm cov hlau nto, ua rau cov hlau nto du thiab huv si, txhim kho corrosion kuj thiab zoo nkauj ntawm hlau. cov khoom, thiab ua tau raws li cov kev cai nruj ntawm high-end teb xws li aerospace thiab tsheb tsim rau hlau qhov chaw.
Nitric acid yog ib qho tshuaj tsis tseem ceeb hauv kev tshawb fawb hauv chav kuaj. Nws koom nrog ntau cov tshuaj tiv thaiv, thiab nrog nws cov oxidation muaj zog, nws tuaj yeem siv rau oxidation, nitrification thiab lwm yam kev sim ntawm cov tshuaj, pab cov kws tshawb fawb los tsim cov tebchaw tshiab, tshawb xyuas cov microstructure thiab cov khoom hloov pauv ntawm cov khoom, thiab txhawb kev txhim kho txuas ntxiv ntawm chemistry.
