Advantage Of Ultrasonic Cleaning:
1. It can clean entirely for your all laboratory instrument.
2. It can improve accuracy of your experiments.
3. It save your time and labor.
4. It can be used for other application like dissolution,extraction
and etc.
5. It is enviromentally cleaning method and you don't need any
harmful solvent.
FAQ:
1. How Can I Enhance the Cleaning Process?
It depends on the item you intend to clean and the type of
ultrasonic cleaner you are using. However, for optimal cleaning,
set a suitable temperature and timing for the cleaning process. The
size of the ultrasonic cleaning machine and the cleaning solution
used also determines how well it cleans the item.
2. Which Cleaning Solutions Should I Not Add to the Water?
Solutions that have low flash points should not be added. The
cavitation process works by releasing energy, which is converted to
heat and then to kinetic energy. As a result, high-temperature
gradients are generated in the solutions. Using flammables, bleach,
acids, or other such agents produces even higher temperature
gradients that can be extremely risky. Here is a list of effective
cleaning solutions:
· Alkaline Solutions: With a pH of 10 or higher, they are great for
cleaning stainless steel, metals, zinc, tin, copper, and cast iron.
Alkaline solutions also work well when cleaning ceramics, glass,
and plastic materials.
· Acidic solutions: they have a pH of 5 or lower hence, more
aggressive than alkaline solutions. As such, acidic solutions are
used for cleaning specific materials, e.g., removing oxides from
metals as long as the solution contains inhibitors that protect the
base material.
· De-ionized water: it is great for cleaning all kinds of
material-metals, plastics, rubber, glass, and fabrics.
· High Caustic solutions: these are special alkaline solutions used
for removing waxes, heavy grease, and oils from steel, cast iron,
and stainless steel.
How To Start Ultrasonic Cleaning?
Select a location that supports an orderly flow of work. Proximity
to a sanitary drain is ideal for disposing of spent cleaning
solution, but first check with local authorities. While elma tec
clean A4 cleaning solution is biodegradable it’s wise to be sure
it’s OK to pour down the drain.
Following is a brief description of the fuel injector cleaning
process:
Fill the tank half full of water and add the correct amount of
cleaning solution concentrate. As an example, for the ¾ gallon tank
add approximately 2/3 cup; for the 1.6 gallon tank 1-1/4 cup.
Continue adding water to the tank fill line.
Degas the solution by operating the ultrasonic cleaner for about 20
minutes. This drives off cavitation inhibiting entrained air and
also mixes your solution. The degassing step must be performed
every time you prepare fresh cleaning solution.
When you are ready to clean:
Carefully position the fuel injectors in the basket with nozzle
holes facing up. It’s important that the solution accesses the
interior of the injectors.
Activate the ultrasound, lower the basket into the solution and
place the lid on the tank to reduce evaporation and noise. Set the
timer for 15 minutes. Cleaning time depends on condition and can be
adjusted either way. Depending on fuel injector configuration it
may be beneficial to remove the basket and reposition the
injectors. (Note the solution will get hot, do not reach into it,
and consider wearing protective gloves.)
When satisfied rinse the injectors in fresh water and blow dry with
an air hose.
Bath Maintenance
Contaminants that float to the surface should be skimmed off and
set aside. When the cleaning solution loses its effectiveness it
must be replaced. Drain the tank and dispose of the solution and
collected skimmings, according to local regulations. Follow the
cleaner’s instruction manual on cleaning the tank then fill it with
fresh solution.
