Dab tsi yog Ultrasonic Homogenizer?
Dec 25, 2024
Ib qho ultrasonic homogenizer, tseem hu ua ultrasonic processor los yog sonicator, yog ib qho kev kuaj ntsuas uas siv cov suab nrov zaus (ultrasound) kom agitate thiab zom cov khoom, hlwb, los yog lwm yam ntaub ntawv nyob rau hauv cov kua los yog ncua kev kawm ntawv. Cov txheej txheem no, hu ua ultrasonic homogenization los yog sonication, yog dav siv nyob rau hauv scientific, industrial, thiab kev kho mob daim ntaub ntawv rau cov dej num xws li kev cuam tshuam ntawm tes, particle loj txo, emulsification, thiab sib tov.
Ultrasonic homogenizer ua haujlwm los ntawm kev hloov hluav taws xob hluav taws xob mus rau hauv kev vibrations ntawm lub transducer. Cov kev vibrations no kis tau los ntawm kev sojntsuam lossis lub horn, uas yog raus rau hauv cov qauv. Thaum cov ultrasonic tsis siv rau cov qauv, lawv tsim kev hloov siab ceev, tsim cov npuas hauv cov kua. Raws li cov npuas vau (ib qho tshwm sim hu ua cavitation), lawv tsim cov cua sov hauv zos thiab shear rog uas tuaj yeem sib cais cov khoom los yog cov hlwb.
Qhov kev siv thiab zaus ntawm lub ultrasonic tsis tuaj yeem tswj tau, tso cai rau kev tswj xyuas meej ntawm cov txheej txheem homogenization. Cov txheej txheem tuaj yeem raug kho kom zoo kom ua tiav cov teebmeem sib txawv, xws li:
Particle loj txo: Ultrasonic nthwv dej tsoo cov khoom loj rau hauv cov me me, txo lawv qhov loj thiab txhim kho lawv cov kev faib tawm.
Cell cuam tshuam: Cov neeg kho tshuab muaj zog ua rau tawg qhib hlwb, tso tawm cov ntsiab lus hauv lub cev rau kev tsom xam lossis kev ua haujlwm ntxiv.
Emulsification: Sonication tuaj yeem tsim cov emulsions ruaj khov los ntawm kev tawg cov tee loj rau hauv cov me me, ua kom yooj yim sib xyaw ntawm cov kua dej tsis sib haum.
Deagglomeration: Pawg ntawm cov khoom tuaj yeem tawg mus rau hauv ib tus neeg rau kev ua haujlwm ntau dua lossis kev ntsuas.
Cheebtsam ntawm Ultrasonic Homogenizer
Ultrasonic Generator: Lub tshuab hluav taws xob muab lub zog hluav taws xob uas tsav cov txheej txheem ultrasonic. Nws converts txheem hluav taws xob fais fab mus rau high-frequency suab tsis.
Transducer: Cov khoom siv no hloov cov hluav taws xob hluav taws xob los ntawm lub tshuab hluav taws xob mus rau hauv cov tshuab kev vibrations.
Horn / sojntsuam (Sonotrode): Qhov no yog ib feem uas ncaj qha hu rau tus qauv. Lub horn amplifies mechanical vibrations thiab xa mus rau hauv cov qauv. Nws tuaj yeem muaj ntau yam duab thiab ntau thiab tsawg nyob ntawm daim ntawv thov.
Kub Tswj System: Ultrasonic homogenization generates tshav kub, yog li kev tswj kub yog feem ntau tsim nyog kom tsis txhob overheating tus qauv, uas yuav ua rau puas rhiab cov ntaub ntawv.
Txias System: Lub kaw lus no pab kom dissipate cov cua sov tsim thaum lub sij hawm sonication txheej txheem, tswj kev ncaj ncees ntawm cov qauv thiab tiv thaiv kev puas tsuaj vim yog kub heev.
