Liquid motion within and around a submerged part is one of many ways of enhancing both cleaning and rising processes. In an earlier blog, The BIG Four agitation was described as one of the “big four” variables having a major impact on cleaning and rinsing. In simple terms, agitation means moving the processing liquid relative to …
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 …
First of all, I would like to thank those of you have become “regulars” to the blog. Having written over 165 “informational” entries now, I am anxious to lift the blog to another level including reader discussions. Reader comments have always been welcome. For those of you who haven’t figured it out, all you have …
Preceeding blogs have described two ways of reducing the ionic content of water for use in washing and rinsing applications. Although both reduce ionic content, the process commonly called “De-Ionization” uses a treated resin to capture ions while the “Reverse Osmosis” process uses a semi-permeable membrane. Choosing between the two in the design of a cleaning process …
Preceeding blogs have discussed de-ionized or “DI” water, its benefits and its uses at some length. Today’s blog will discuss “Reverse Osmosis” water otherwise known as “RO” water. RO water is like a second cousin of de-ionized water. In the de-ionization process, potentially ALL ions are removed resulting in water that can approach the ultimate limit for pure …
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 …
Cleaning, as we’ve all known it for years, is a matter of taking a “dirty” part and making it a “clean” part using whatever means is necessary and feasible. Typically, the cleaning process involves mechanical removal of contaminants or the use of a chemistry to dissolve and dilute the contaminant. In the case of an …
