Cleaning your firearm collection is likely the least enjoyable part of owning guns for most people. It’s often tedious and involves both time and effort, not to mention lots of “elbow grease” and the use of smelly solvents. Fortunately, with the advent of tabletop-sized ultrasonic cleaners, gun owners are free to enjoy their hobby without all the hassle of hand-cleaning their firearms. [Read more…]
You’ve got a big job ahead of you: stripping stubborn, old paint away from machined parts. Hours of work, scrubbing away with a wire brush, your head spinning with the odor of solvents that always seem to creep inside your mask no matter how good the mask is. If you’re not doing it personally, then you’re talking about one of your employees doing it, meaning lost time to labor and money down the drain. But that isn’t the case if you use an ultrasonic cleaner to do the job.
What is an Ultrasonic Cleaner?
Simply put, an ultrasonic cleaner is a device that utilizes piezoelectric transducers, which vibrate against a diaphragm to produce high-frequency sound waves. When these ultrasonic waves pass through a liquid medium and strike against an object immersed in the bath, they produce millions of microscopic bubbles. These bubbles are formed and collapse over and over again in milliseconds, releasing powerful jets of energy in a well-known physical effect called “cavitation.” The effect of cavitation, coupled with water temperature and specially designed detergents, thoroughly and gently cleans even the most stubborn contaminants away from the surface of the object. With the right detergent, even old paint can be stripped away with little effort or time spent.
Let Ultrasonic Cleaner Cavitation do the Heavy Lifting
Cavitation is so powerful–temperatures in excess of 10,000°F and pressures in excess of 10,000 PSI are briefly generated–that it literally blasts away paint and other contaminants. But because the implosion is so fast it does not damage surfaces when kept under control. As an added benefit, the microscopic bubbles penetrate cracks, crevices and blind holes that are impossible to reach by hand. All told, ultrasonic cavitation accomplishes what hand cleaning and solvents cannot do, both more thoroughly or faster.
Selecting an Ultrasonic Cleaning Solution
Today’s ultrasonic cleaning solutions are biodegradable – including those that work best for paint removal. For example, Omegasonics has created a detergent called OmegaChem, which is a unique cleaning agent specifically formulated to be a paint remover. OmegaChem is used with ultrasonic cleaners to remove petroleum-based paint and paint residue from a variety of surfaces, including spray gun nozzles. OmegaChem, though formulated for paint removal, is still far safer for use and exposure than solvents, and unlike solvents, can be disposed of in environmentally-friendly ways far more easily.
Keep in mind that each paint removal task may be different. When putting the parts that need the paint stripped from them in the ultrasonic cleaning device, follow the instructions. You may need to experiment, too. Some cycles may take longer than others depending on what you’re working. However, after finding out what solutions and times work best, you’ll soon become an expert.
Ultrasonic Cleaning Preparation and Maintenance
As always, follow the manufacturer’s instructions given for both the detergent and the ultrasonic cleaner. For example, fresh ultrasonic cleaning solutions should be degassed to remove entrapped air before you start the cleaning cycle. You can do this by filling the tank with solution, then turning on the ultrasonic cleaner and letting it run for 40 minutes or until air bubbles stop rising to the surface. This degassing will make the solution more effective, as air bubbles interfere with cavitation and make it less powerful.
Before putting the painted object in the solution bath, scrape away any loose or blistered particles. Don’t forget the detergent solution temperature. Make sure you set the ultrasonic cleaner thermostat for the recommended solution temperature, as per manufacturer’s instructions. Place the parts in the basket in a way they do not contact each other, lower the basket into the solution and cover the unit with the supplied lid. At the end of the cycle, remove the basket, rinse the parts and inspect to be certain the paint is removed satisfactorily. The parts should be thoroughly dried before repainting. This can be done with air drying or by using a drying cabinet.
Remember: when the detergent no longer cleans effectively, it should be changed. Dispose of it along with the accumulated paint residue according to local regulations. Since you’re not handling a toxic solvent, chances are you’ll be able to dispose of it along with the other wastewater from your operations. Take the time to thoroughly clean the tank following the manufacturer’s recommendations before refilling it with fresh solution.
If you do a lot of paint stripping, you’ll find that using an ultrasonic cleaner plus the proper detergent solution will definitely save you money and labor costs in the long run. Contact our experts at Omegasonics at 888-989-5560 or email us at Omegasonics@Omegasonics.com to find out more.
In a previous article, we discussed the different types of contaminants that can be removed by various ultrasonic cleaning solutions. In this article, we’ll talk about the different types of materials that can be cleaned using these same solutions in our ultrasonic cleaners, and why choosing one over another may better suit our needs.
Just as with contaminants, there may be more than one type of ultrasonic cleaning solution that may work with a particular material; final selection then will be based on the type of contaminant to be removed, as well as the relative speed or aggression with which we’d like the article cleaned. Even the finish of the part may affect our decision.
During the last quarter of 2017, the Tax Cuts and Jobs Act was passed into law–the first major piece of tax reform legislation since the Reagan era. As with taxes in general, thinking about the tax code and accompanying legislation can feel overwhelming. However, since it will affect you and your business, you need to know what some of these changes are and how they can impact your bottom line.
First: the new tax reform bill won’t impact your 2017 taxes. File those as usual–you won’t see any of the below changes until you file your 2018 taxes. However, it’s a good idea to consult with a tax professional to decide what changes you need to be making now, if any, in order to prepare yourself for filing your 2018 taxes.
Consider the incredible speeds, temperatures, and pressures that aerospace industry parts routinely endure. Even the best engineered parts must be kept scrupulously clean when in operation. Even the slightest error could cost precious lives and millions of dollars in damage. Traditionally, aerospace parts, whether they were from jet airplanes or rockets, have been precision cleaned in specialized cleaning facilities offsite, creating additional exorbitant overhead costs in labor, time and money.
