Ultrasonic defoaming hauv cov kua ntxuav tais diav yog ib daim ntawv thov ntawm ultrasonic kua kho tshuab hauv kev lag luam tshuaj txhua hnub. Nws siv cov nyhuv cavitation ntawm ultrasound los cuam tshuam ua npuas ncauj stability, daws teeb meem ua npuas ncauj thaum lub sij hawm tsim khoom, cia, thiab siv cov tshuaj ntxuav tais diav. Cov hauv qab no yog ib qho kev ntsuam xyuas ntawm nws cov xwm txheej ntawm daim ntawv thov, cov qauv txheej txheem, cov txheej txheem tsis, kev xaiv cov khoom siv, thiab qhov zoo thiab cov kev txwv, muab cov lus qhia siv rau kev tsim khoom lossis lwm yam xwm txheej:

I. Core Application Scenarios (Industrial + Consumer Extension)
Qhov teeb meem foaming hauv cov kua ntxuav tais diav feem ntau yog los ntawm cov khoom muaj zog foaming ntawm surfactants (xws li LAS thiab AES). Ultrasonic defoaming tsom rau tag nrho cov saw ntawm "ua npuas dej tiam - persistence - siv," nrog cov xwm txheej tseem ceeb suav nrog:

 

1. Muaj Ntau Lawm Qib (Core Scenarios)
Cov khoom xyaw Mixing Defoaming: Thaum lub sij hawm ntxuav tais diav ua kua, surfactants, dej, thiab additives (xws li thickeners thiab fragrances) yog tov ntawm kev kub ceev, yooj yim tsim ib tug loj npaum li cas ntawm nplua ua npuas ncauj, ua rau:

** Kev nthuav dav ntawm cov kua ntim, txo kev siv cov cuab yeej siv (yuav tsum muaj chaw txaus rau ua npuas ncauj);

** Ua npuas ncauj ntxiab huab cua, cuam tshuam rau homogenization tom ntej, pom, lossis ua kom raug;

** Ua npuas ncauj residue ua rau cov khoom tsis sib xws (xws li txheej txheej, npuas cov cim).** Ultrasonic tsis tuaj yeem defoam hauv lub sijhawm tiag tiag thaum sib tov lossis defoam hauv cov khoom sib xyaw ua npuas.

**Defoaming ua ntej sau:** Thaum lub sij hawm detergent filling, ua npuas ncauj tau yooj yim ua rau overflow ntawm lub raj mis lub qhov ncauj thiab tsis raug ntim ntim. Ultrasonic pretreatment tuaj yeem rhuav tshem cov npuas me me hauv cov kua, txhim kho kev ua kom tiav thiab ntsuas qhov tseeb.

**Defoaming nyob rau hauv lub tso tsheb hlau luam:** Thaum lub sij hawm cia ntawm tiav lawm detergent, ua npuas ncauj yuav re-tsim vim kev thauj mus los co thiab kub hloov. Ultrasonic nthwv dej tuaj yeem ntsia tau rau ntawm phab ntsa sab hauv ntawm lub tank cia kom tsis tu ncua ua npuas npuas.

2. Daim ntawv thov pej xeem / tshwj xeeb txuas ntxiv

**Industrial Cleaning Support:** Nyob rau hauv industrial tu kab siv detergent ua ib tug tu tus neeg saib xyuas (xws li rau kho vajtse thiab yas qhov chaw tu), ua npuas ncauj ntau heev yuav cuam tshuam cov kev khiav hauj lwm ntawm cov tshuaj ntxuav thiab nyob twj ywm rau ntawm workpiece nto. Ultrasonic nthwv dej tuaj yeem muab tso rau hauv lub tank ntxuav kom defoam thaum ntxuav.

**High-Concentration Detergent Dilution:** High-viscosity, high-concentration detergents are prone to generate stubborn foam when dilution. Ultrasonic-pab dilution tuaj yeem tawg ua npuas ncauj sai sai, tiv thaiv nws los ntawm lingering rau ncua sij hawm tom qab dilution.

II. Cov Ntsiab Cai: Cov Ntsiab Lus Tseem Ceeb ntawm Ultrasonic Foam Breaking
Lub stability ntawm detergent ua npuas ncauj nyob ntawm lub zog ntawm cov kua zaj duab xis (lub zog quab yuam ntawm cov hluav taws xob ob txheej tsim los ntawm surfactant molecules) thiab roj retention (tsis muaj peev xwm ntawm cov pa hauv cov npuas dej kom nrawm nrawm). Ultrasonic nthwv dej tawg npuas los ntawm ob lub ntsiab lus:

 

1. Cavitation nyhuv (Qhov Tseem Ceeb)
Thaum ultrasound propagates hauv cov kua, nws ua alternating siab -siab thiab qis- siab zones (frequency 20kHz ~ 1MHz). Microbubbles (cavitation npuas) yog tsim nyob rau hauv qhov qis - siab.
Cavitation npuas sai sai poob rau hauv qhov siab - qhov chaw siab, tso tawm tam sim no kub kub (txog txhiab K) thiab poob siab nthwv dej (siab mus txog pua pua ntawm cov cua), cuam tshuam ncaj qha rau cov kua zaj duab xis ntawm cov npuas dej, ua rau cov kua zaj duab xis tawg thiab ua npuas dej kom tawg.

Rau 10 ~ 100μm microbubbles hauv detergent (uas yog qhov nyuaj rau cov pa defoamers ua haujlwm nrog), cov nyhuv cavitation tuaj yeem cuam tshuam qhov sib npaug ntawm qhov sib npaug ntawm cov kua zaj duab xis, ua tiav qhov sib sib zog nqus defoaming.

2. Vibration Disturbance (Secondary Factor) Lub siab - zaus vibrations ntawm ultrasound yog kis mus rau lub npuas nto, ua rau resonance thiab nruam stretching thiab thinning ntawm cov kua zaj duab xis, nws thiaj li ua rau rupture vim nro imbalance.

Kev vibration kuj txhawb nqa cov kua convection, ua kom cov pa tawm nrawm ntawm cov npuas dej thiab txo cov npuas dej.

Viscosity (25 degree): 100 ~ 1000 mPa·s (cov tshuaj ntxuav tes tsis tu ncua), tsawg zaus thiab siab zog; Yog tias viscosity> 1000 mPa·s (hom hom), lub zog ceev yuav tsum tau nce mus rau 2 ~ 3 W / cm², thiab lub sijhawm ua haujlwm txuas ntxiv.

Ua Npuas Ncauj Hom: Nto ua npuas ncauj (yooj tawg yooj yim) tuaj yeem txo lub zog; sab hauv microbubbles (yooj yim tawg) yuav tsum muaj zaus ntawm 50kHz lossis siab dua, ua ke nrog nplawm.
