Ultrasonic Cleaning Solutions
Ultrasonic cleaning solutions are used in ultrasonic cleaning equipment as an important part of the process because the solution performs the actual cleaning. Because water alone cannot completely clean a dirty part or product, an ultrasonic cleaning solution is critical for cleaning and sanitizing processes. These solutions contain ingredients that are selected based on the chemical and physical properties of the contaminants and the surface material and they are designed to optimize cavitation, the formation and collapse of bubbles.
Ultrasonic cleaning solutions are either water-based or solvents that containchemical or organic ingredients. They aremainly composed of detergents and surfactants, or wetting agents thatreduce the surface tension of water. Cleaning solutions are also chosenbased on their flow characteristics. Those with static fluid conditionsfacilitate the formation of standing wave patterns, thereforemaximizing cavitation strength. Flammable solutions are avoided becauseof the risk of fire; the solution is heated to over 100 degreesFahrenheit. Acids and bleach are also seldom used because they damagemany materials such as stainless steel and create hazardousenvironments for ultrasonic cleaner operators. Metals like stainlesssteel, iron and magnesium need highly caustic solutions, while glass,ceramics and plastics need moderately alkaline or neutral syntheticsolutions.
Ultrasonic cleaning solutions are the most important part of a cleaning system although they are one component of the larger unit. All ultrasonic cleaning equipment has, at minimum, a transducer, a generator and an immersion tank.The parts are placed in the tank which holds the solution. These tanksvary in size and shape though generally they are rectangular and madefrom stainless steel or aluminum. The process begins when cavitationoccurs. The transducer is either mounted to the tank or is lowered intothe fluid. When the transducer introduces ultrasonic sound waves intothe tank, innumerable minute and intense imploding bubbles release bothenergy and heat to provide a highly efficient method of scrubbing bothexposed and concealed surfaces of the immersed parts. There is a directconnection between how the frequency and the number of implosions whichallows for a high level of control; high frequencies ideal for theremoval of very small particles without harming the surface of theparts being cleaned. The level of cleaning solution must be carefullymonitored. If there is a noticeable decrease in the quality of thecleaning action, the system needs to be refilled with cleaning agents.After the ultrasonic cleaning process has finished, most systems rinsethe objects or parts clean of any leftover cleaning solutions.More Ultrasonic Cleaning Solution Information
