Ultrasonic is sound generated above human audible level. In real life, high
pitch sound is created by high frequency, and alternatively, the low and base
tone is created by low frequency. Frequencies above 16 kHz in general are
being considered as ultrasonic. Typical ultrasonic frequencies used for
cleaning purpose are from 20 kHz to 80 kHz.
How a sound can clean?
A physical effect called "cavitations" ultrasonic generates in liquid is
responsible for the cleaning process. Cavitations are form when ultrasonic
travels through liquid. When a sound wave travels through water, it stretches
and compresses the water medium to transmit sound. When the amplitude
of such sound wave increases to a level when water cannot hold the stretch,
the sound literally tears the water apart, and millions of vacuumed "bubbles"
are formed under such negative pressure.
The sizes of vacuumed "bubbles" increase until their equilibrium are
reached; the "bubbles" then rapidly compress by water and create millions of
tiny liquid jets.
The jet actions release tremendous amount of energy stored within
vacuumed bubbles; each "bubble" is estimated to have a temperature of
more then 5000 degree Celsius and a pressure of more then 10,000 PSI at
molecular level when such implosion takes place. The huge amount of
pressure releases at each "bubble" provides an ideal physical phenomenon
responsible for the effective cleaning action ultrasonic cleaner offers.
Ultrasonic cleans cracks
Cavitation takes place every where liquid can reach; during the cleaning
process, the article being cleaned is submerged into water or cleaning
solution, millions of micro-sized "bubbles" created by ultrasonic are capable
of reaching into fine trends or cracks to clean.
Ultrasonic Cleaning: frequency higher the better?
The frequency of an ultrasonic cleaning device has nothing to do with the
cleaning power. The ideal cleaning frequency is determined by what is going
to be cleaned. Simply speaking, the higher the frequency the more capable it
is to remove smaller particles.
Ultrasonic, the answer to environmental-friendly cleaning for home
Although ultrasonic has been an effective industries' cleaning solution for
decades, environmentally unfriendly, chemical-based cleaning method is still
widely used at home. Best and More believes ultrasonic will be the next
generation cleaning solution for home.
