4.4 Influences of ultrasound output

4.4 Influences of ultrasound output power
The same conditions as mentioned in Section 4.1
and Section 4.2, 20 kHz, 80°C, the influences of ultrasound
output power were also studied.
There was an optimal value of ultrasound output
power as shown in Fig. 5, which was about 150 W.
The ultrasonic irradiation condition was very important
in the whole process. There were two mechanisms
that could explain the ultrasonic influences. (1) Aggregating
effect. The water drops aggregated with the
ultrasound irradiation, which was helpful to the emulsion
demulsify. (2) Cavitation effect. The ultrasound
cavitation had the emulsification affection. When the
intensity of ultrasound was below the cavitation
threshold, the aggregation appeared, the results of ultrasound
irradiation being demulsified. When the intensity
of ultrasound increased over the cavitation
threshold, the results of ultrasound irradiation were
shown as emulsification.

4.4 Pengaruh daya output USG
Kondisi yang sama sebagaimana dimaksud dalam Pasal 4.1
dan Pasal 4.2, 20 kHz, 80 ° C, pengaruh USG
daya output juga dipelajari.
Ada nilai optimal output USG
daya seperti ditunjukkan pada Gambar. 5, yang sekitar 150 W.
Kondisi iradiasi ultrasonik sangat penting
dalam seluruh proses. Ada dua mekanisme
yang bisa menjelaskan pengaruh ultrasonik. (1) Menggabungkan
efek. Tetes air dikumpulkan dengan
iradiasi USG, yang membantu untuk emulsi
demulsify. (2) Kavitasi efek. USG
kavitasi memiliki kasih sayang emulsifikasi. Ketika
intensitas USG berada di bawah kavitasi
ambang batas, agregasi muncul, hasil USG
iradiasi yang demulsified. Ketika intensitas
USG meningkat selama kavitasi
ambang, hasil iradiasi USG yang
ditampilkan sebagai emulsifikasi.
