Hydrogen peroxide (H₂O₂) ntawm qhov concentration ntawm 90% yog ib daim ntawv muaj zog heev thiab muaj zog ntawm cov tshuaj lom neeg uas muaj npe nrov. Nws cov ntawv thov tshwj xeeb thiab feem ntau nyob hauv thaj chaw uas yuav tsum tau ceev faj heev thiab cov kws tshaj lij kev tuav pov hwm vim muaj kev pheej hmoo cuam tshuam nrog kev siv. Ntawm qhov kev xav no, hydrogen peroxide feem ntau yog siv rau hauv kev lag luam thiab kev siv dav hlau, thiab nws txoj kev tuav yog ua raws li kev cai nruj nruj.
1. Aerospace thiab Rocketry
Rocket Propellant:
Monopropellant thiab Bipropellant: Thawj qhov kev siv ntawm 90% hydrogen peroxide yog nyob rau hauv kev lag luam aerospace, tshwj xeeb tshaj yog raws li lub foob pob hluav taws. Hauv nws daim ntawv decomposed, nws tsim cov pa thiab oxygen, ua rau nws ua haujlwm zoo. Nws tuaj yeem siv tau ob qho tib si raws li monopropellant, qhov twg nws tsuas yog siv tshuaj lom neeg sib xyaw ua ke, thiab ua ib feem ntawm lub tshuab bipropellant, qhov twg nws cuam tshuam nrog lwm cov roj.
Daim ntawv thov keeb kwm: Keeb kwm, 90% hydrogen peroxide tau siv hauv tshuab foob pob hluav taws, suav nrog qee qhov qauv ntawm cov foob pob hluav taws thaum ntxov thiab hauv cov tshuab propulsion ntawm cov dav hlau ceev. Piv txwv li, nws tau siv nyob rau hauv lub npe nrov X-15 foob pob ua ntxaij dav hlau thiab cov qauv ntxov ntawm Tswb Rocket Belt.
Oxidizer:
Muab Oxygen rau combustion: Hauv cov tshuab bipropellant, hydrogen peroxide ua raws li oxidizer. Nws siab concentration tso cai rau ib qho tseem ceeb oxygen tso zis, uas yog ib qho tseem ceeb nyob rau hauv lub combustion txheej txheem ntawm foob pob ua ntxaij cav.
2. Submarine Propulsion
Diesel-Electric Submarines: Qee lub nkoj siv hluav taws xob siv hluav taws xob siv hluav taws xob siab hydrogen peroxide ua cov oxidizer, tso cai rau lawv khiav lawv cov cav hauv qab dej tsis tas yuav tsum muaj huab cua los ntawm qhov chaw.
3. Kev tsim tshuaj thiab kev tshawb fawb
Synthesis ntawm Organic thiab Inorganic Compounds: Nyob rau hauv tshuaj synthesis, 90% hydrogen peroxide yog siv los ua ib tug haib oxidizing tus neeg sawv cev. Nws koom nrog hauv kev tsim ntau yam organic thiab inorganic tebchaw nyob rau hauv kev tswj kev lag luam ib puag ncig.
Kev Tshawb Fawb Tshwj Xeeb: Hauv qee qhov chaw tshawb fawb qib siab, cov ntsiab lus siab hydrogen peroxide yog siv hauv cov txheej txheem sim thiab cov tshuaj tiv thaiv uas yuav tsum tau muaj zog oxidant.
4. Kev siv ib puag ncig
Kev kho cov dej qias neeg thiab huab cua: Txawm tias tsawg dua, hydrogen peroxide tuaj yeem siv rau hauv ib puag ncig kev siv xws li kho cov dej tsis huv thiab huab cua. Nws muaj zog oxidative zog pab zom cov pa phem.
5. Kev saib xyuas kev nyab xeeb thiab kev tuav pov hwm
Yuav tsum tau ceev faj heev: Kev tuav 90% hydrogen peroxide xav tau ceev faj heev. Nws yog corrosive heev thiab tuaj yeem ua rau kub hnyiab heev thaum sib cuag nrog daim tawv nqaij lossis qhov muag.
Cia thiab ruaj khov: Nws yuav tsum tau muab khaws cia rau hauv cov thawv tshwj xeeb, feem ntau yog ua los ntawm cov hlau tsis muaj steel lossis txhuas, kom tsis txhob decomposition thiab tswj kev ruaj ntseg. Nws tseem khaws cia rau hauv qhov chaw txias, qhov cua kom txo tau qhov kev pheej hmoo ntawm kev tawg sai thiab tawg.
Cov cuab yeej tiv thaiv: Cov cuab yeej tiv thaiv zoo, suav nrog hnab looj tes, tsom iav kev nyab xeeb, thiab cov khaub ncaws tiv thaiv, yog qhov tseem ceeb thaum tuav cov concentration ntawm hydrogen peroxide.
Risk ntawm Explosion: Vim nws cov reactivity siab thiab muaj peev xwm decompose sai, tso pa oxygen thiab cua sov, muaj ib qho kev pheej hmoo ntawm tawg, tshwj xeeb tshaj yog nyob rau hauv muaj cov organic cov ntaub ntawv los yog tej yam hlau.
6. Kev tswj hwm thiab kev txhawj xeeb txog kev thauj mus los
Kev cai nruj: Kev tsim khoom, khaws cia, thauj, thiab siv 90% hydrogen peroxide yog tswj hwm thoob ntiaj teb. Cov kev cai npog cov khoom xws li kev thauj mus los, kev cia khoom, thiab kev tso cai siv.
Environmental Impact: Thaum hydrogen peroxide decomposes rau hauv dej thiab oxygen, nws cov concentration siab yuav ua rau muaj kev phom sij rau ib puag ncig yog tias tsis tswj kom raug.
