Ultrasonic Sonochemical Ua Haujlwm Kev Cuam Tshuam Thiab Xa Khoom

Ultrasonic sonochemical manipulation cov tshuaj tiv thaiv thiab synthesis

Sonochemistry yog daim ntawv thov ntawm ultrasound rau tshuaj lom neeg cov tshuaj tiv thaiv thiab kev ua haujlwm. Lub tshuab ua rau sonochemical cuam tshuam hauv cov dej yog qhov tshwm sim ntawm acoustic cavitation.

Altrasonic ultrasonic kuaj thiab cov cuab yeej siv khoom siv yog siv ntau hauv cov txheej txheem sonochemical. Ultrasonic cavitation siv zog thiab nrawm rau tshuaj lom neeg cov tshuaj xws li synthesis thiab catalysis.

Qhov siv ntawm kev ua kom nrawm yog ib qho ntawm cov tseem ceeb tshaj plaws los cuam tshuam rau kev hloov pauv ntawm lub zog mus rau hauv cavitation. Kev nrawm ntau ua rau siab dua qhov sib txawv. Qhov no nyeg nce qhov tshwm sim ntawm kev tsim cov tshuab nqus plua plav es tsis txhob tsim cov vuag tawm los ntawm cov kua. Yog li, qhov nce siab dua qhov siab dua yog qhov feem me ntawm lub zog uas hloov mus ua cavitation. Thaum ib qho ultrasonic transducer, qhov sib zog ntawm kev nrawm tau piav qhia los ntawm kev ua kom dav ntawm oscillation.

Ntau dua ntawm cov cua sov ua rau muaj kev tsim cov cavitation zoo dua. Cov kev lag luam muaj khoom ntawm Altrasonic Ultrasonics tuaj yeem tsim qhov ntau ntawm 115 115m. Cov txheej txheem loj no tso cai rau lub zog siab xa hluav taws xob sib piv dab tsi nyob rau hauv lem tso cai los tsim lub zog siab ua kom sib npaug txog li 100 W / cm³.

Ntxiv nrog rau qhov sib zog, cov kua yuav tsum nrawm nrawm rau hauv ib txoj hauv kev los tsim cov poob qis hauv kev sib txuam, kev sib txhuam thiab nthwv dej. Rau qhov no, txoj kev zoo tshaj plaws yog ib qho kev xav ntawm lub teeb ib leeg.

Ultrasound siv vim nws qhov cuam tshuam hauv cov txheej txheem, xws li:

1. kev npaj ntawm cov hlau ua kom nquag plias los ntawm kev txo cov ntsev hlau

2. tiam ntawm activated hlau los ntawm sonication

3. sonochemical synthesis ntawm hais los ntawm nag lossis daus ntawm hlau (Fe, Cr, Mn, Co) oxides, xws li siv raws li catalysts

4. impregnation ntawm hlau lossis hlau nres rau ntawm kev txhawb nqa

5. kev npaj ntawm cov hlau daws teeb meem

6. kev cuam tshuam nrog cov hlau ntawm hauv situ tsim hom tsiaj

7. cov tshuaj tiv thaiv cuam tshuam nrog cov hlau tsis yog cov khib nyiab

8. crystallization thiab nag lossis daus ntawm cov hlau, alloys, zeolithes thiab lwm cov khib nyiab kev hloov kho ntawm morphology saum npoo thiab cov particle loj los ntawm kev ua haujlwm siab interparticle sib tsoo

1). tsim kom muaj cov ntaub ntawv zoo tshaj plaws nanostructured, nrog rau cov chaw siab siab hloov chaw ntawm cov hlau, alloys, carbides, oxides thiab colloids

2) Cov Khoom Muaj). agglomeration ntawm cov muaju

3). smoothing thiab tshem tawm ntawm passivating oxide txheej

4). micromanipulation (fractionation) ntawm qhov me me

9. dispersion cov khib nyiab

10. npaj ntawm colloids (Ag, Au, Q-qhov loj qhov me CdS)

11. sib cuam tshuam ntawm cov qhua lwg me me mus rau hauv cov tswv tsev dej rau cov txheej txheem ua kom yooj yim

12. sonochemistry ntawm polymers

1). kev ua kom tsis haum thiab kev hloov kho ntawm cov polymers

2) Cov Khoom Muaj). hluavtaws polymers sonolysis ntawm cov pa phem nyob hauv dej
