Look around you. Triangles are everywhere! Any structure requiring a strong and rigid construction depends on triangles to achieve that goal. Even though they might not be obvious or even seen for that matter, triangles are at work wherever strength and rigidity are important. The triangle is the only two dimensional polygon that if constructed …
If you have worked around ultrasonic cleaning systems, you may have noticed that most of them are plastered with stickers warning against the use of flammable materials as cleaning agents. To those who are not familiar with various ultrasonic phenomena, these warnings may seem a bit extreme. In fact, however, flammable liquids may become even …
The terms “flammable,” “inflammable,” and combustible all describe materials that will burn. Semantics and nebulous definitions of each have led not only to a great deal of confusion over the years but, probably, to several unfortunate accidents. In doing the research for this blog, I discovered that there is no simple and fast definition of …
Although, fortunately, we seldom encounter flammability issues in cleaning, it’s a good idea to be familiar with some of the terms like Upper and Lower Flammability and Explosive Limits for the sake of safety. In the preceding blog, it was explained that three things were needed to produce a fire – Fuel, Oxidizer, and a …
There is always a temptation to use solvents in cleaning applications. Although it is a “no-brainer” that there is a risk of fire or explosion when using a flammable solvent, it won’t hurt to review what flammability is all about. You may be familiar with the “Combustion Triangle.” In simple terms, there are three things …
“Vanishing Oils” are often considered as an alternative to more conventional lubricants in light duty stamping and forming operations. The conception is that these formulations actually “vanish” eliminating the need for cleaning once there is no longer a need for lubrication. True, depending on circumstances, they may reduce or eliminate the need for cleaning but in fact, …
In order for a lubricant or coolant to be effective it must possess the very properties that make it difficult to remove. In industrial machining, stamping and metal forming applications, selecting lubricants and coolants wisely can greatly simplify cleaning processes required to remove them once these processes are complete. Effective lubricants must be able to adhere …
Lubricants and coolants are two of the most common contaminants requiring removal in industrial cleaning. Understanding their basic nature and how they work may help lead to the solution of many cleaning problems Lubricants help prevent friction between two surfaces moving relative to one another by, in effect, providing a barrier between the two surfaces …
Filters used to filter air, water and chemicals in industrial processes can cost thousands of dollars and more. Some filters are intended to be renewable by cleaning. Other filters, even some considered “disposable,” can be recovered for re-use using ultrasonic cleaning techniques. A filter, as we discussed in earlier blogs (search “filter”) is a device …
This blog is in response to recently received reader questions regarding the best designs for baskets and fixtures used in ultrasonic cleaning applications. The blog Reader Questions – Baskets for Ultrasonic Cleaning addressed previous questions. Today’s question concerns the use of metallic fasteners in the construction of baskets and fixtures to hold parts for ultrasonic cleaning. The …
