Cleaning of various valuable objects is considered as an integral part for most of household and manufacturing industries. And nowadays people are giving preference to Ultrasonic cleaners. These techniques are widely being used in most areas.
Ultrasonic cleaning involves removing strains and other types of contaminants from the objects by immersing it in a tank of liquid. And this tank is usually flooded with high-frequency sound waves. Moreover, these waves are non-audible and create a gentle scrubbing action within the fluid. This type of cleaning normally lasts between three to six minutes but can also exceed for 20 minutes depending on the object to be cleaned.
The two main components of this ultrasonic cleaner are generator and transducer. The generator is used for converting electrical energy to desired ultrasonic frequency. And then the transducer converts electrical energy from the generator into mechanical vibrations.
Ultrasonic cleaners are known for cleaning different types of objects like watches, coins, window blinds, firearms, car fuel injectors, musical instruments, jewelry, lenses and other types of optical parts. Jewelry workshops, watchmakers and other electronic repair workshops make use of this ultrasonic cleaning.
According to a study, ultrasonic energy reduced the time needed for a solution to destroy bacteria from 3.5 hours to 30 minutes.
Working of Ultrasonic Waves
This process is carried out by a very high-frequency electrical energy that is converted by a transducer into high-frequency sound waves. Then the ultrasonic energy enters the liquid within the tank causing the rapid formation of bubbles. This phenomenon is known as cavitation. As soon as the bubbles implode and cavitation occurs, the cleaning solution rushes into the gap left behind by the bubbles.
Therefore the cleaning power of your ultrasonic equipment is known by the transducer’s performance.
Why Should You Prefer Ultrasonic Cleaning?
• Environmental friendly
Nowadays most of the cleaning techniques make use of heavy chemical cleansers. And these cleaning agents contain harmful compounds like esters and chlorinated hydrocarbons which pollutes groundwater supplies. Moreover, the vapors from these chemicals are also highly toxic. But when you consider ultrasonic cleaner they make use of water-soluble detergents rather than harsh chemicals.
• Works Safely
Ultrasonic cleaners not just only prevent workers from inhaling harmful chemical gases but also prevents sharp instruments that contain biological contaminants. Moreover, this cleaner is very safe for the cleaning purpose as you just need to place the instrument in the tank and then add water and detergent and turn on the machine.
Most of the people have found ultra-sonic cleaning more efficient than hand cleaning and other machine-based cleaning methods. The best part about this cleaning is that it lowers the use of 3 main components.
This technique involves the less use of water than the other hand-cleaning methods or traditional washing machines.
Ultrasonic cleaners are very efficient and make use of less electricity.
The ultrasonic cleaners are very quick and effective than other types of cleaning. And they usually perform their work in very less time.
• Gentle Cleaning
This type of cleaning is very useful for dealing with delicate items such as jewelry or other precious instruments as this technique involves both a thorough cleaning and a delicate process. The cavitation effect produced by with type of cleaning allows the mixture of water and detergent to reach the narrow crevices and remove unwanted residue.
• Multiple uses
Ultrasonic cleaning is used for almost all the purposes starting from household chores to federal law agencies. This technique is used mostly in homes for cleaning jewelry, collectible coins for removing dust, rust and skin oils. In commercial places, it is used for cleaning parts and tool of cars. Moreover, police officers, sheriffs, and federal agents clean their weapons and handcuffs with the help of ultrasonic cleaners.
The sizes of these types of machine can vary from small models to larger units depending on your requirement. Some cleaners make use of specialized detergents to remove dirt while other equipment may only require water and a small amount of detergent.
Factors That Enhance and Limits Ultrasonic Cleaning:
There are several properties that can either enhance or limit the cleaning and all these factors are discussed below.
Temperature plays a very important role in providing effective cleaning. With the increase in temperature, the detergent solution’s vapor pressure also increases. It is always recommended to mix the detergent with warm water to enhance the effectiveness of ultrasonic cleaners.
Temperature between 11 F and 140 F is usually required for water-based detergent.
To avoid any type of damage, the temperature of the water should keep low to prevent it from exceeding the instrument’s temperature parameters.
2. Instrument Baskets, Trays
These baskets, trays are designed in such a way that it doesn’t provide any kind of inconvenience. These trays are made from stainless steel and are usually wired, meshed to ensure efficient passage of the ultrasonic waves.
Moreover, they are useful in:
• Maximizing the exposure of the ultrasonic waves
• Minimizing movement of the soiled instruments to the ultrasonic waves
• Optimizing cleaning by preventing the contact of the instruments to the bottom of the cleaner
3. Instrument Arrangement
In this method, the contaminated object is kept in the processing chamber for effective cleaning. Usually, ultrasonic energy is uni-directional and travels from its source in one direction through the detergent solution.
4. Cleaning Time
The cleaning time includes the following factors:
• Quantity of contaminated instrument in the processing basin
• Degree of instrument contamination
• Frequency and power of the ultrasonic cleaner
5. Power of Cavitation
Power of cavitation of the ultrasonic cleaners can be easily calculated by placing some material in the chamber filled with water. The weight of the material will determine its power. An increase in the power of the ultrasonic energy will cause an increase in cavitation activity.
