When particles are the enemy, my general rule is filter, filter, filter! The cost of filtration is small compared to the overall benefit even if it is only “insurance.” There is, of course, the initial cost of installation (filter housings, pumps, plumbing, etc.) but the cost after that is going to be pretty much fixed provided …
A few years ago I wrote a post about the possible perils of automated valves. The thrust of the post was that many automated valves rely on significant line pressure to hold the valve tightly closed. In applications where there is only gravity pressure, as in drain lines for example, valves that are perfectly effective under high …
What happens when parts exit the cleaning process dirty? First of all, PANIC, especially in the case of critical cleaning for optics, semiconductor, disc drive and other industries where particles that can’t even be seen with a microscope render product worthless and unrecoverable! Then there is the inevitable quest for, “Why this is happening?” Although this scenario is …
The applications for wire seem limitless. Wire is used for electrical conductors as well as in structural applications including suspension bridges and other architectural creations. There are about 1 ½ miles of wire in a typical car today and often over 150 miles in a jetliner. A cruise ship? Somewhere around 3,000 miles! Wire diameters …
The cost of acquiring and disposing of cleaning chemistry is usually a major contributor to the overall cost of an industrial or precision cleaning process. Removing contaminants from cleaning solutions can potentially extend their useful life and reduce overall cleaning costs. Traditional filters including those of the bag and cartridge variety are commonly used to remove solid (particulate) contaminants …
I admit, I stole that title from my grandma Bertha. But even in this day, the concept is applicable. Cleaning one thing is one thing, cleaning thousands of things is another. Let’s think about that. Cleaning, as we have discussed before, really amounts to moving contaminants from the surfaces being cleaned and sequestering them in another …
In the blog The Effect of Temperature on Ultrasonics, temperature was identified as a major variable in ultrasonic cleaning due to the impact it has on many physical properties of liquids. This blog addresses the effect that chemistry has on the physical properties of liquids and the resulting effect on ultrasonics. Most ultrasonic cleaning utilizes chemistry …
The physical properties of liquids have a significant effect on their ability to cavitate and produce imploding cavitation bubbles useful for ultrasonic cleaning. Since other factors including temperature and chemistry can have an effect on the physical properties of liquids, these, too, play a significant role in ultrasonic cleaning. This blog explores the effect that a number …
The notion persists that more power is better in ultrasonic cleaning applications. In the past, this may have been an absolute as the amount of power available was often limited by the limitations of the equipment that was available. As we discussed in a recent blog however, today’s ultrasonic equipment is no longer limited in power …
A previous blog discussed the ramifications of contaminant loading on cleaning. This time let’s look at the long term effects on cleaning chemistry. In lab testing, the ability of chemistry to withstand extended use is often not challenged. Chemistry is prepared and used for short term cleaning trials to verify the cleaning process. In long …
