Ultrasonic Emulsification Tshuab Sib Sau

Zoo ntawm ultrasonic emulsification piv rau cov neeg kho tshuab kev ntxhov siab siab ceev ceev shearing:

1. Cov emulsion muaj ib tug zoo me me particle (qhov zoo tshaj plaws yuav ncav cuag 100 nm)

2. Cov emulsion tsis yooj yim rau stratify

3. Kev siv hluav taws xob tsawg zog (1 / 10-1 / 20 ntawm txhua yam kev kho) JP600G ultrasonic extraction / emulsification tsev, ntim 20L, ultrasonic zog 1000W, zaus 28KHZ, khoom SUS304 stainless hlau, fais cua sov fais fab tuag 2000W, cov hwj huam muaj peev xwm Adjustable cov moos adjustable cov cheb adjustable cov kub tswj.

Tej yam yuav tsum paub txog thaum twg cov neeg siv ultrasound:

Ultrasonic emulsification:

Ua ntej, lub formulation ntawm cov emulsion muaj xws li cov nyiaj emulsifier.

Thib ob, qhov kev xaiv ntawm emulsification lub sij hawm tsis yog ntev li ntev tau. Cov txheej txheem emulsification yog ib txheej txheem ntawm dispersion thiab polymerization. Raws li cov kev ntsuam xyuas uas twb muaj lawm, cov khoom xaj ntawm emulsified ntawm 10-15 feeb yuav yog me me li 100 nm. Qhov tseem ceeb tshaj plaws yog kev xaiv ntawm cov zauv zaus cheb. Muaj 16 kev xaiv. Qhov qis dua tus nqi, lub npuas tuab thiab qhov muaj zog zog. Qhov siab dua tus nqi, tus thinner lub npuas thiab lub zog me zog. Sib txawv extraction lossis emulsifying tshuaj pauv cov cheb los coj txawv cov teebmeem thiab kev ua haujlwm.

Thib peb, qhov zoo ntawm ultrasonic emulsification:

1. Cov emulsion ua los ntawm ultrasonic emulsification muaj me me nruab nrab droplet me me ntawm 0.2 mus rau 2 um; qhov kev sib faib me me yog qhov nqaim, thiab yuav yog 01 mus rau 10 um lossis tsawg dua.

2. Ultrasonic mis nyuj concentration siab, cov concentration ntawm cov ntshiab emulsion yuav tshaj 30%, thiab cov emulsifier tau txog li 70%.

3. Lub tsim emulsion yog ruaj khov dua. Ib qho tseem ceeb ntawm phacoemulsification yog tias nws muaj peev xwm tsim muaj emulsion ruaj khov tsis muaj los yog nrog tsawg emulsifier.

4. Hom tshuaj emulsion tuaj yeem tswj tau. Kev siv phacoemulsification, O / W (roj-hauv-dej) thiab W / O (dej-hauv-roj) emulsions tau npaj nyob rau hauv tej lub suab txawv teb chaw; Txawm li cas los, nws yog tsis yooj yim sua kom siv mechanical emulsification, tsuas yog qhov xwm ntawm lub emulsifier. Yuav kom tswj tau cov hom emulsion.

5. Toluene yog emulsified nyob rau hauv dej, ua ib hom emulsion raws li cov suab tsis tshua muaj suab, thiab lwm hom emulsion nyob rau hauv cov suab siab mob siab.

6. Ultrasonic emulsification kom tsawg zog los tsim emulsion.
