Blackstone Ultrasonics was founded in the mid 1950’s in the hope that the addition of ultrasonic agitation to a conventional clothes washer would revolutionize laundering of fabrics. It didn’t take long before it was recognized that ultrasonic techniques weren’t going to be effective – at least not by simply adding ultrasonic transducers to a conventional …
Gee Whiz! I was sure somebody would challenge me on the last blog about washing dishes at home. But, since there are no comments (or fire bombs) in my inbox, I guess everybody agrees that the most efficient way to wash dishes at home is the “old fashioned” way with a dish rag and dish drainer. …
Water, the “universal” solvent is the center of most cleaning applications in the home. Water, at least in my location in the US, is readily available, plentiful and relatively inexpensive. Water plus a small amount of overly expensive and competitively merchandised chemicals does an admirable job of cleaning dishes and clothes which constitute about 50% of …
The preceeding blog discussed what is probably the “granddaddy” of all cleaning challenges – burned-on carbon. But, as those of us who have been in the cleaning business since Noah launched the ark know, there are a bunch of other cleaning challenges that defy modern technology. In general, these challenges fall into a small group …
The technology of parts cleaning is a very sophisticated science today. Most cleaning challenges can be met with the proper combination of equipment, chemistry and technique. In my 45 year involvement with parts cleaning, I have seen many twists and turns along the way. Applications that were considered “impossible” 10 or 20 years ago are …
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 …
