Thaum sib xyaw cov kua dej tsis zoo rau hauv emulsions, cov dej me me thiab kev faib tawm yog qhov tseem ceeb hauv emulsion stability. Cov khoom siv Ultrasonic emulsification tuaj yeem tsim cov tee dej zoo heev thiab nqaim. Feem ntau, cov khoom siv sonication tuaj yeem tsim sub - micron droplets thaum npaj emulsions batchwise lossis hauv - kab. Tsis zoo li kev kub siab homogenizers, lub siab shear rog tsim los ntawm cov khoom siv ultrasonic emulsification tuaj yeem emulsify cov kua dej ntau dua xws li cov roj hnyav (HFO). Qee cov formulations yuav xav tau qhov sib ntxiv ntawm emulsifiers lossis stabilizers. Nyob rau hauv rooj plaub no, phacoemulsification cov cuab yeej kuj pab sib tov cov emulsifier tusyees.

Rau ntau qhov kev lag luam, kev tswj kev loj hlob ntawm cov kab mob thiab cov algae hauv dej yog txheej txheem ze ze rau kev tsim khoom. Ultrasonic dej kho cov cuab yeej paub txog nws cov txiaj ntsig ntawm cov qauv ntawm tes ua rau cov cell lysis thiab cell tuag, nrog rau nws lub zog ntxuav vim kev poob siab. Tsis tas li ntawd, nrog rau cov kauj ruam yooj yim heev tab sis ua tau zoo sonication, biofilm, residues tuaj yeem raug tshem tawm ntawm cov tso tsheb hlau luam, chim, ntim thiab txawm lim. Lub siab zaus kev co thiab cavitation shear quab yuam tsim los ntawm cov khoom siv ultrasonic tshem tawm cov dej thiab kua dej. Cov seem seem yog yooj yim yaug tawm yam tsis tas yuav muaj cov tshuaj ntxuav kom huv.

Particles thiab txawm dispersions tau yooj yim tau los ntawm ultrasound. Cov khoom siv Ultrasonic tuaj yeem siv los tsim micro - thiab nano - nplai nplua - nplai dispersion thiab depolymerization. Ultrasonic dispersion cov cuab yeej tuaj yeem tawg cov hmoov agglomerates hauv cov kua uas cov pa agitators thiab siab shear mixers tsis tuaj yeem tawg. High cavitation shear rog disperse thiab homogenize cov agglomerated hais, ua rau thaj tsam siab dua.

Cell disintegration los yog lysis yog ib tug txheej txheem nyob rau hauv niaj hnub qauv npaj nyob rau hauv biotechnology kuaj. Lub hom phiaj ntawm lysis yog rhuav tshem ib feem ntawm cov phab ntsa ntawm tes los yog tag nrho cov cell kom tso biomolecules. Yog li - hu ua lysates yuav suav nrog, piv txwv li, plasmids, receptor assays, proteins, DNA, RNA, thiab lwm yam. Cov kauj ruam tom ntej tom qab lysis yog kev sib cais, kev cais cov organelle lossis / thiab cov protein rho tawm thiab khaws cia. Cov cuab yeej siv ultrasonic yog ib qho cuab yeej siv rau kev ua tiav cell lysis thiab rho tawm.

Microbial inactivation yog txheej txheem tseem ceeb hauv kev ua zaub mov. Vim muaj kev xav tau ntau ntxiv rau cov khoom noj tshiab, ua haujlwm me me, kev lag luam teb rau cov neeg siv khoom xav tau los ntawm kev hloov cov ntaub ntawv rwb thaiv tsev nrog cov txheej txheem me me. Txij li cov kab mob microorganisms yog qhov tseem ceeb ntawm cov zaub mov lwj, cov txheej txheem khaws cia yuav tsum tau siv rau lawv. Ultrasonic sterilization khoom yog ib tug tsis yog - thermal technology uas inactivates microorganisms nyob rau hauv ib yam khoom kom zoo khaws cia lub organoleptic zog, khoom noj khoom haus thiab functionality ntawm cov khoom. Qhov kom zoo dua ntawm sonication yog tias qhov kev siv ntawm sonication tuaj yeem tswj tau tag nrho, kom cov kab mob inactivation tuaj yeem ua tiav.

Rau kev tsim cov tshuaj pleev ib ce, kev sib xyaw ntawm cov khoom xyaw yog ib kauj ruam tseem ceeb. High - hwj chim ultrasound enables nplua - grained homogenization, dispersion thiab emulsification, xws li rau kev npaj ntawm cream thiab tshuaj pleev ib ce, ntsia thawv polish thiab tshuaj pleev ib ce. Lub peev xwm ntawm ultrasound rau extraction thiab preservation kuj paub zoo. Txij li ntau cov khoom xyaw zoo nkauj xws li lipids, cov protein, cov tshuaj tsw qab lossis cov tshuaj pleev xim los ntawm cov hlwb tau txais los ntawm kev rho tawm, cov khoom siv ultrasound yog cov cuab yeej muaj peev xwm rau qee cov qauv tshiab.

Cov txheej txheem ua haujlwm, xws li kev sib xyaw thiab homogenization, kev rho tawm, ruaj khov thiab khaws cia, cov txheej txheem ib txwm siv maj mam hloov los ntawm cov txheej txheem tshiab xws li kev kho ultrasonic. Ultrasound yog ib qho uas tsis yog - thermal ua zaub mov. Cov txiaj ntsig ntawm sonication yog nws cov kev ua tau zoo, nrawm thiab huv, uas txo cov khoom poob thiab txhim kho cov zaub mov zoo los ntawm kev khaws cia freshness thiab vitamins.

Kev lag luam kws tshuaj

Daim ntawv thov ntawm cov khoom siv ultrasound hauv kev lag luam tshuaj muaj ntau yam, xws li kev sib xyaw ntawm cov tshuaj sib txuas, tshem tawm cov tshuaj nquag (xws li phenols, flavonoids los ntawm cov nroj tsuag), emulsification (emulsion ntawm cov tshuaj pleev ib ce, tshuaj pleev thiab tshuaj pleev), liposomes Kev npaj (encapsulation) lossis inactivated. tshuaj tiv thaiv kab mob thiab kab mob kis kab mob. Hauv kev tsim tshuaj, kev siv cov khoom siv ultrasonic tuaj yeem ua kom muaj peev xwm ntau lawm los ntawm kev nce cov khoom. Cov khoom siv ultrasound muaj peev xwm siv tau rau loj - scale kws tshuaj npaj nyob rau hauv daim ntawv ntawm batch los yog tas mus li txheej txheem.

Nanomaterials

Cov khoom siv lub cev (xws li optics thiab hlau nplaum, tshwj xeeb kub, melting point, thiab nto reactivity) ntawm nanomaterials (xws li nanotubes, graphene, nanodiamonds, ceramics, hlau oxides, thiab lwm yam) tau nyiam ntau xim raws li cov ntaub ntawv tshiab. Tab sis qhov me me ntawm cov khoom ntawm nanomaterials, qhov nyuaj dua nws yog ua. Siab - lub zog ultrasound feem ntau yog tib txoj hauv kev los cuam tshuam rau nanoparticles. Qhov cuam tshuam ntawm lub hwj chim ultrasound suav nrog ntau yam kev siv hauv cov ntaub ntawv chemistry thiab kev loj hlob, catalysis, electronics, zog, thiab biology thiab tshuaj. Lub siab - lub zog ultrasonic generator yog ib txoj hauv kev zoo kom tau txais cov nanoparticles xav tau.
