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, …
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 …
This blog explores some common mistakes made in the application of de-ionization hardware. Although a properly engineered and installed de-ionization system will prevent these potential mistakes at the start, post-installation modifications by those less knowledgeable about de-ionizing technology don’t always respect good design practices. Temperature Limits – In general, de-ionization systems are not intended to …
This blog includes hints on ways to improve the quality and reduce the cost of de-ionized water. Those who use DI water in their processes know that the cost of DI water can be a major contributor to the overall cost of a process. The proper design and maintenance of a DI water system is …
Next to water filtration and “softening,” de-ionization is probably the next most common water treatment. Ions in water interfere with many cleaning processes and cause water spots on drying after rinsing. The common measure of the amount of ions in water is “resistivity.” The more “resistive” water is, the less ions it contains. Water from a municipal …
Some means of reducing water hardness as we’ve described in preceding blogs is an almost universal first step in making water pure enough for most cleaning applications. But water softening only addresses the removal of only a few of many contaminants that are commonly present in our water supplies. The remaining contaminants range from ions …
