User’s FAQ About Ultrasonic Cleaning
Most frequent questions and answers
Ultrasonic cleaners are used to clean many different types of objects, including jewelry, eyeglasses, denture, watchband, scientific samples, surgical instruments, hardware, hand tools, fishing reels, window blinds, firearm components, car fuel injectors, musical instruments, etc.
Please review “APPLICATION OF ULTRASONIC CLEANER “to learn more.
Plastic is not a favorable material for ultrasonic cleaning. Low density and flexible plastics such as polyethylene (LDPE), actually absorb at least 30% of the ultrasonic power, lessening the cleaning action.
You should never clean a complete watch in an ultrasonic ultrasonic cleaner.
Ultrasonic cleaning bases water, you should consider the water resistance rating of your watch, the other important point to consider is maybe your watch already has cracks that are not visible by eyes.
The ultrasonic vibrations will speed the cracks, water may get trapped inside and damaging the watch.
At the frequency of 37kHz with a household ultrasonic cleaner, it should not harm fingers. And it will remove the dirt from your nail. But it will feel to you like a mild electrical shock.
According to the sensitivity of each person, they have different feelings.
But do not put hands in an industrial or high-frequency ultrasonic cleaner. The low frequency is more powerful, the high frequency is more penetrating.
Generally, ultrasonic cleaning is safe for all materials; however, prolonged soak to ultrasonic cleaning solutions and chemicals may interact adversely with the surface of certain metals.
For fine cleaning of very delicate jewelry, electronics with polished surfaces, it should be considering the frequency and power, instructions for safe use of an ultrasonic cleaning, consult the manufacturer of the product.
Note: Aluminum is a softer metal; surfaces can suffer pitting in ultrasonic cleaning. For cleaning aluminum parts, getting rapid and effective cleaning without damaging the parts is more difficult.
Ultrasonic cleaners will generate heat during the cleaning process.
You should never use flammable and explosive liquids in an ultrasonic cleaner. Dangerous conditions will occur if flammable and explosive liquids are used for ultrasonic cleaning.
In addition, do not use toxic cleaning solution, which is dangerous for the operator.
Business requires a balance between time and money. Unfortunately, the two are often at odds. After a long period of verify of using ultrasonic cleaning, this is the way can save you both time and money.
Speeding up the Cleaning Process
When you have parts that are covered in dirt, carbon, and grime, you need to spend a lot of time to get that contamination removed. This typically involves a long soak in a chemical solution, followed up by a person scrubbing with brushes. This time-consuming process is not necessary when using an ultrasonic cleaner.
Instead of hours and hours of labor, all that is required for a throughout cleaning is to disassemble the parts, put them in the bath, set the functions and walk away. While the cycle is running, that manpower can be repurposed to other jobs.
The tasks that took multiple hours were reduced to one. That means more time to take on other clients and increase income. Not only does an ultrasonic cleaner save time, but it helps make money while doing it.
When using ultrasonic cleaner at home, the tap water is sufficient. If you need to remove some oil stains, you can add a few drops of dish-washing liquid.
For industrial cleaning, the solution you select plays a major role in successful ultrasonic cleaning operations. Ultrasonic cleaning solutions are available in a wide variety of formulations – each designed for specific cleaning tasks. Please consult with your solution supplier depending on local environmental requirements.
Note: Do not use strong acids and alkalis, because the ultrasonic bath made of stainless steel, which will corrode the ultrasonic bath.
Ultrasonic cleaning is a physical cleaning method. When removing chemical contaminants on the metal surface, such as rust and paint, it is necessary to add a cleaning solution to the water.
Under the action of ultrasound, chemical contaminants react between the solution and the surface of the part, thereby improving the cleaning ability and shortening the cleaning time.
In fact, the ultrasonic cleaner does produce noise. When the ultrasonic cleaner is working, the “zizi” noise heard by the human ear is caused by ultrasonic cavitation, which is called cavitation noise. If there is whistling noise, it is possible to eliminate it.
At present, manufacturers usually use a variety of methods to reduce noise without affecting the cavitation, such as using foot pads, or adding sound-proof cotton to the lid and optimize the equipment shell.
Yes, ultrasonic cleaners are known for removing the oil, sweat, etc. stains from gold, silver jewelry.
And it’s safe, do not need the chemical detergent. But when your silver jewelry is oxidized, you need to add a professional detergent to remove these oxides.
Dental pliers, chisels, scalpels, dental drills, etc. are generally used in dentistry. Hospitals must be responsible for the health of patients and attach great importance to the cleaning and disinfection of dental instruments.
Ultrasonic cleaner is among recommendations in the dentistry to remove contaminants from reusable dental instruments. 15 minutes cleaning before sterilization avoids heat “baking on” blood, tissue and other organic residues that cause infection problems. Ultrasonic cleaners are favored by dentists because of its good cleaning effect, high efficiency, environmental protection, and low cost.
