Ultrasonic Cleaning with Flammable Solvents

ultrasonic cleaning using flammable solvent

Cleaning with flammable solvents requires extreme caution in any case but ultrasonic cleaning with flammable solvents requires specially designed equipment and procedures.  That’s because of the real danger of a fire or explosion if spilled solvent or vapors are ignited by sparks from internal electronics or external sources.  This post describes equipment to use and precautions to observe for ultrasonic cleaning with low flash point flammable solvents. 

But first, some explanations and relevant regulations.

What is a Flash Point?

Flammable solvents have different flashpoints. In brief, the lower the flashpoint the more flammable they are.  This is important when cleaning with flammable solvents.

Fortunately there is help.

The American Chemical Society publishes a table of common organic solvents that includes flash points.  Examples of low flash point volatile solvents are 1-propanol at 59⁰F (15⁰C), acetone at -4⁰F (-20⁰C)  and toluene at 39⁰F (4⁰C).

Ultrasonic Cleaner Solution Selection Tips

The ultrasonic cleaner solution you select plays a major role in successful ultrasonic cleaning operations. Ultrasonic cleaner solutions are available in a wide variety of formulations – each designed for specific cleaning tasks. These solutions are also referred to as cleaning chemistries and in some cases “soaps.” We’ll stick with ultrasonic cleaner solution in this post and provide you with tips on how to make the right selection.

How an Ultrasonic Cleaner Solution Works

ultrasonic_cleaing_solution_selection_v3

Regardless of the chemistry, an ultrasonic cleaner solution works by a process called cavitation.  This is defined as the implosion of millions of microscopic vacuum bubbles in an ultrasonic cleaner’s tank filled with the solution.  Bubbles are created by generator-powered transducers vibrating at ultrasonic frequencies such as 37,000 cycles per second (37 kHz). 

When bubbles contact products to be cleaned they implode violently (but safely) against all wetted surfaces to blast loose and carry away contaminants.

Medical Ultrasonic Cleaner Performance Validation

OK-Sonic

In its “Guideline for Disinfection and Sterilization in Healthcare Facilities” the CDC notes “Ultrasonic cleaning removes soil by cavitation and implosion in which waves of acoustic energy are propagated in aqueous solutions to disrupt the bonds that hold particulate matter to surfaces.”

Sub-par performance of a medical ultrasonic cleaner could lead to trouble.  That’s because a number of factors can compromise the efficiency of these cleaners, leaving contaminants that might not be revealed by visual examination.   This is especially relevant when medical instruments and labware have complex, difficult-to clean configurations.  OK-Sonic™ medical ultrasonic cleaner performance validation strips provide added assurance that your ultrasonic cleaner is doing its job. … Read the rest

Choosing and Using an Ultrasonic Cleaner for Carburetors

Use an Ultrasonic Cleaner to Restore Carburetors

Fuel injection systems have replaced the carburetor but a Gili’s Automotive post states “While carburetors may not have a life in new vehicles today, chances are good that they’ll still be used for many years to come.”  That’s because “Carburetors, unlike fuel injection systems, are relatively straightforward when it comes to repairing them. Fuel injection requires sophisticated computers, but carburetors require only a screwdriver and a willingness to get one’s hands dirty.” Keeping carburetors clean is easy with an ultrasonic cleaner.

This post explains to shade tree and professional mechanics why ultrasonic cleaners for carburetors keep these vital assemblies (which were invented by Karl Benz in 1885) functioning. … Read the rest

How to Select an Eco-Friendly Ultrasonic Parts Cleaner

How to Develop an Eco-Friendly Metal Parts Cleaning System

Challenges relating to cleaning new or refurbished parts, many of which require subsequent processing such as painting and plating, are increasing due to environmental regulations.  This post shows you why an ultrasonic parts cleaner using eco-friendly biodegradable parts cleaning solutions is a favored alternate to washing and spraying with harsh solvents along with their associated disposal concerns.   

Why Choose an Ultrasonic Parts Cleaner?

Let’s start with why you should consider an ultrasonic parts cleaner.

Cleaning is faster, safer and easier when using an ultrasonic parts cleaner.  Machining oils, grease, residues left from molding or handling, soot and other contamination are difficult and can be dangerous to remove by soaking in harsh and sometimes flammable solvents, manually scrubbing or power washing in solvent parts washers. 

Moreover these methods do not reach difficult-to-access surfaces such as cracks, crevices, small diameter and blind holes where contaminants remain and can cause future problems.… Read the rest
