ULTRASONIC CLEANING
Introduction:
Ultrasonic cleaning is a process that uses ultrasound for rapid and complete removal of contaminants from objects by immersing them in a tank of liquid flooded with high frequency sounds waves. These non-audible sound waves leads to momentary creation of vacuum "tears" usually referred to as "bubbles" in the fluid which immediately and violently implode to create millions of microscopic jets of liquid which gently scrubs the parts that are submerged in the tank. These tears or cavities created gently remove contaminants without damage.
How Ultrasonic cleaning Works:
In Ultrasonic cleaning the object to be cleaned is placed in a chamber that contains a suitable solution. An ultrasound generating transducer is built into the chamber which converts high frequency electrical energy into high frequency sound waves – ultrasonic energy. This makes compression waves in the liquid of the tank which ‘tear’ the liquid apart, deserting many millions of microscopic ‘voids’ or ‘partial vacuum bubbles’. These bubbles collapse with enormous energy. The higher the frequency, the smaller the nodes between the cavitation points, which takes into consideration cleaning of more complicated detail. In spite of the fact that these cavities are produced by the millions, the distribution of these cavities is dictated by the ultrasonic frequency in operation. Every Ultrasonic cleaning system produces a cleaning action that is distributed as a series of equidistant bands of activity. These bands are known as "standing waves", and cleaning activity between standing waves is just a fraction of the energy which is produced at a standing wave location. This is the reason why selection of the appropriate ultrasonic frequency is so important for developing an effective cleaning process.
The efficiency of the transducer will influence both the cleaning time and efficacy achieved during the cleaning cycle. A low quality transducer will use more power and take more time to clean items than a good transducer. This is why Ultrasonics has invested in this area in such great depth, keeping in mind the end goal to give you a benchmark transducer. There are numerous factors which require considering when cleaning items. Heat, power, frequency, detergent type and time all influence the cleaning process yet the flexibility of ultrasonics implies that these can all consolidated into the procedure keeping in mind the end goal to accomplish the effective results.
Ultrasonic cleaning Applications:
Ultrasonic cleaning systems are used for a wide variety of applications and processes.
Healthcare – Ultrasonic cleaning is used in the decontamination process of dental instruments. In optical industry delicate cleaning action of instruments and lenses is achieved by this type of cleaning. Podiatrists and chiropodists use Ultrasonic cleaning as an alternative method to manual scrubbing in their decontamination process. Pre-sterilization cleaning of surgical instruments is also an application of Ultrasonic cleaner.
Industrial use - Ultrasonic cleaners are used in the automotive industry, sporting field, printing, marine, medical, pharmaceutical, electroplating, disk drive components, food and beverage, engineering, Printing Technology and Equipment and weapons industries.
Laboratory use - Ultrasonic cleaners are used in scientific and laboratory sites to activate cell disruption and homogenizing. Ultrasonic baths are used by chemical and pharmaceutical laboratories for solvent degassing and preparing samples. From Ultrasonic cleaning lab plastic ware and glassware to mixing and emulsifying samples, Ultrasonic cleaning have a broad range of laboratory uses.
Special treatments – Ultrasonic cleaning is utilized in some special treatments like
Tattooist
Acupuncture
Body piercing
Hairdressers
Conclusion:
Ultrasonic cleaning has long been standout among-st the methods of cleaning across a diverse range of applications. No other technique is as fast or efficient for cleaning hard substrates or complicated parts. Reduced emissions, biodegradable waste and a safer environment for employees are among the advantages. It is this capacity to clean even the most inaccessible areas which makes ultrasonics a perfect cleaning system for medical instruments.
