I’ve always known that cleaning inside blind holes was a difficult task. In a previous blog, I demonstrated using video just how difficult it is to get liquids and/or air in and out of a blind hole. My plan was to approach the problem logically (largely based on intuition), and offer readers some solutions to …
We have discussed earlier the importance of drying in a cleaning process. Despite the several hardware options available, hot air dryers remain the “go to” in industrial cleaning processes today. Today’s blog will discuss the basic design concept of hot air dryers and how they function. The main components of hot air dryers are a …
The chemistries used in industrial cleaning processes are predominantly either dry (granular or powder) or liquid. Dry chemistries cover a wide range of density and flow characteristics. In fact, two batches of the “same” dry chemistry may have considerably different properties. Each liquid product has its own specific gravity and viscosity characteristics but may also vary in other …
In the past week or so, I have had several people walk into my office and ask a question that has been popular for as long as I can remember – – “What is the ratio of cross section to depth that defines the cleanability of a blind hole?” As is so often the case in …
Most cleaning processes are comprised of a number of discreet steps. A wash followed by one or more rinses and then a dry would be a typical cleaning process. As parts being cleaned are moved from one process step to the next, they are vulnerable to potential risks by conditions not directly related to cleaning. Whether related …
