Previous blogs have explained the benefits of relative motion between the part being cleaned or rinsed and the liquid in contact with the part. Relative motion can be accomplished by moving either the part or the liquid relative to the other. Ultrasonic agitation has also been identified as beneficial to cleaning and rinsing for somewhat the …
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 …
