Ultrasonic kua tov khoom

Dab tsi yog qhov kev xav ntawm ultrasonic sonochemistry?

Qhov no tshwm sim yog hu ua cavitation.

Cavitation is the formation, growth, and implosive collapse of bubbles in a liquid. Cavitational collapse produces intense local heating (5,000K), high pressures (1,000atm), enormous heating and cooling rates (>109K/sec) thiab dej dav hlau ntws (400km/h). Muaj ntau txoj kev los tsim cavitation, xws li los ntawm high-pressure nozzles, rotor-stator mixers, los yog ultrasonic processors. Nyob rau hauv tag nrho cov tshuab, lub zog input yog hloov mus rau hauv kev sib txhuam, turbulences, nthwv dej thiab cavitation.

Qhov feem ntawm lub zog input uas hloov mus rau hauv cavitation nyob ntawm ntau yam piav qhia txog kev txav ntawm cov cavitation-tsim cov cuab yeej hauv cov kua.Qhov kev siv ntawm acceleration yog ib qho tseem ceeb tshaj plaws uas cuam tshuam rau kev hloov pauv ntawm lub zog mus rau cavitation.

Kev nrawm dua ua rau muaj qhov sib txawv siab dua.

Qhov no nyob rau hauv lem tsub kom qhov tshwm sim ntawm creation ntawm lub tshuab nqus tsev npuas, es tsis txhob ntawm cov creation ntawm nthwv dej propagating los ntawm cov kua.Yog li, lub acceleration ntau dua yog cov feem ntawm lub zog uas yog transformed rau hauv cavitation.Yog hais tias tus ultrasonic transducer. , lub amplitude ntawm oscillation piav qhia qhov kev siv ntawm acceleration.

Cov amplitudes siab dua ua rau muaj txiaj ntsig zoo ntawm cov cavitation. Ntxiv nrog rau qhov kev siv zog, cov kua yuav tsum tau nrawm rau hauv txoj hauv kev los tsim kom muaj kev poob qis hauv cov ntsiab lus ntawm turbulences, kev sib txhuam thiab yoj tiam. Rau qhov no, txoj kev zoo tshaj plaws yog ib qho kev taw qhia ntawm kev txav mus los. Qhov no ua rau ultrasound ua tau zoo txhais tau tias rau dispersing thiab deagglomeration tab sis kuj rau milling thiab zoo sib tsoo ntawm micron-loj thiab sub micron-loj hais.

Ntxiv nrog rau nws lub zog hloov dua siab tshiab, ultrasonication muaj kev tswj xyuas tag nrho ntawm qhov tsis muaj amplitude, siab, kub, viscosity thiab concentration. Qhov no muaj peev xwm kho tau tag nrho cov kev txwv no nrog lub hom phiaj los nrhiav cov kev ua haujlwm zoo tshaj plaws rau txhua yam khoom tshwj xeeb.

Qhov no ua rau muaj kev ua tau zoo dua thiab ua kom zoo dua qub.

Muaj Kev Ua Haujlwm ntawm Ultrasound Ultrasonic ua ntawm cov khoom tso cai ua txhua qhov sib npaug.

RPS-SONIC's industrial ultrasonic processors feem ntau yog siv rau inline-sonication.Yog li ntawd, lub ncua kev kawm ntawv yog pumped rau hauv lub ultrasonic reactor hlab ntsha. Muaj nws raug rau ultrasonic cavitation ntawm kev tswj kev siv. Lub sij hawm raug yog los ntawm qhov ntim ntawm lub reactor thiab cov khoom noj khoom noj. Inline sonication tshem tawm bypassing vim hais tias tag nrho cov hais dhau lub reactor chamber raws li ib tug txoj kev.

Raws li tag nrho cov hais yog raug rau tib yam sonication tsis rau tib lub sij hawm nyob rau hauv txhua lub voj voog, ultrasonication feem ntau hloov cov tis nkhaus es widening nws. Feem ntau, 'txoj cai tailing' tsis tuaj yeem pom ntawm cov qauv sonicated. Qhov kev xaiv ntawm rov ua ultrasonic los ntawm lub voj teeb enables lub zoo meej sonication kom pom rau txhua txhua xim thiab txhua tus number case formulation. Xws li cov xim pleev xim ua rau cov xim zoo nkauj zoo nkauj thiab qhia tau tias muaj kev ruaj ntseg dua, cov khoom siv sonochemistry muaj zog (kuj nyob rau ntawm qhov kub siab), khov-thaw stability, txo flocculation ruaj khov rheology thiab qis dua viscosity ntawm ntau dua particle loading.

Cov cuab yeej siv hluav taws xob siab siv hluav taws xob ntau dua.Xav txog kev nce nqi hluav taws xob, qhov no cuam tshuam cov nqi ntawm kev ua haujlwm. Vim li no, nws yog ib qho tseem ceeb, tias cov cuab yeej tsis poob ntau lub zog hauv kev hloov hluav taws xob rau hauv cov khoom siv hluav taws xob. Hais txog kev siv hluav taws xob, ultrasound yog lub npe kom muaj zog heev.

RPS-SONIC ultrasonic processors are claimed to have efficiency of >85 xus. Qhov no pab txo cov nqi hluav taws xob thiab ua rau koj ua haujlwm ntau dua. Kev tawg ntawm cov txheej txheem agglomerate hauv aqueous thiab non-aqueous suspensions tso cai rau siv tag nrho cov peev txheej ntawm nanosize cov ntaub ntawv.

Kev soj ntsuam ntawm ntau qhov sib txawv ntawm nanoparticulate agglomerates nrog cov ntsiab lus sib txawv tau pom tias muaj txiaj ntsig zoo ntawm ultrasound thaum piv nrog lwm cov thev naus laus zis, xws li rotor stator mixers, piston homogenizes lossis ntub milling txoj kev, xws li hlaws mills lossis colloid mills.

Parameter:

Daim ntawv thov:

Cov ntawv thov ntawm ultrasonic sonochemistry muaj xws li ultrasonic homogenization, phacoemulsification, ultrasonic dispersion, depolymerization thiab ntub sib tsoo (particle loj txo), cell cuam tshuam thiab disintegration, extraction, degassing, thiab sonochemical dab;

Ultrasonic dispersion tsis xav tau kev siv emulsifiers. Feem ntau, txoj kab uas hla ntawm cov khoom tawg tuaj yeem ncav cuag 1μm lossis tsawg dua. Nws tuaj yeem nqa tawm ntawm cov khoom, kua, thiab roj theem ntawm tib yam khoom, lossis ntawm cov khoom sib txawv, kua thiab roj. Nws tau dav siv nyob rau hauv cov zaub mov kuaj xyuas thiab tsom xam, kev npaj ntawm nanomaterials, thiab lwm yam.

Xws li:

● Xim, titanium oxide, hlau oxide, carbon, thiab lwm yam yog dispersed nyob rau hauv dej los yog hnyav.

● Graphene micronization

● Dispersion ntawm cov khoom fluorescent

● Dispersion ntawm cov ntaub ntawv photosensitive

● Dispersion ntawm dyes nyob rau hauv molten paraffin
