ULTRASONICS
If you need the articles
you are cleaning to be uniformly
ultra clean and to eradicate
rejects in production, there is
no other method as capable or
efficient and convenient as
ultrasound. Blind holes,
orifices, narrow openings and
the such like are left just as
clean as all other surfaces.
Ultrasound passes through most
materials with ease and
penetrates to the very core of
an article being cleaned. For
instance, a mechanical watch or
meter movement can be cleaned
and oiled without disassembly by
using ultrasound.
There are two processes
constantly working in the liquid
of the tank in which the
ultrasound is applied. The
ultrasound creates rarefactions
and compressions within the body
of the liquid. This causes a
phenomena known as catastrophic
cavitation. In other words it is
the continuous production of
thousands of minute implosions
within the body of the liquid
that do the mechanical work on
the article being cleaned.
Simultaneously the effects of
the cavitation cause a
disruption of the boundary layer
that exists between any liquid
and solid interface. This
disruption places whatever
chemicals are being used into
more intimate contact with the
contamination or soil being
removed.
HYDROSONICS
The effect of hydrosonics is the
same as that for ultrasonics,
but the ultrasound is produced
by a different method.
Ultrasonics uses
electro-mechanical transformers
called transducers to produce
the ultrasound whereas
hydrosonics makes use of liquid
whistles to produce the
ultrasound.
Hydrosonics is most cost
effective in very large tanks
and can be more efficient when
high speed cleaning is required
eg. in the production of link
chains or wire. The high speed
processes in the automotive
industry also benefit from this
method.
