In many industrial cleaning processes it is necessary to exhaust emissions that unavoidably result from the cleaning process. The reasons for exhaust can take on a large range – Remove heat that would otherwise raise the temperature in the cleaning area Remove humidity that would otherwise raise the humidity in the cleaning area Remove toxic fumes that might otherwise be dangerous …
In the world of industrial cleaning technology we talk about surface tension a lot! So much so, in fact, that it is hard to enter into any discussion of cleaning without having the subject of surface tension arise. In cleaning chemistry, for example, we are always looking for lower surface tension to promote penetration of small surface features …
A few days ago, I sat down to write what I thought would be a simple explanation of surface tension and how it is measured in the laboratory (a blog which will be published shortly if I can figure all of this out). In doing the normal background research, however, I started to see contradictions …
Wherever there are liquids there are leaks – it’s inevitable. Leaks, of course cost money in downtime and repair of industrial cleaning systems. So, you ask, what is the best defense against leaks. Most leaks occur where one piece of plumbing connects with another. A pipe to a valve, unions, connections to pumps and filters and …
There has been a lot of buzz lately on the internet regarding work at the Oak Ridge National Laboratory to develop a dryer that uses ultrasonics instead of heat to dry things. The major thrust seems to be to replace the conventional domestic clothes dryer (which uses heat to evaporate water) with one that uses ultrasonics …
The environment in the area of an industrial cleaning system is often not a “healthy” one for personnel or equipment. Caustic and acidic cleaning chemistries rise as mist above cleaning processes along with humidity and heat. Although our first thought is to protect personnel from these hazards, the equipment can also suffer serious consequences as a …
When a liquid or a gas flows uniformly and without turbulation, the result is called “laminar flow.” The most visual example of laminar flow for most of us are those arching water displays where perfectly shaped slugs of crystal clear water flys gracefully through the air from one point to another. When I first saw this effect at …
Maximum ultrasonic performance requires the most efficient transfer of ultrasonic vibrations from the ultrasonic transducers to the liquid in the process tank. This is generally accomplished by applying ultrasonic transducers directly to the exterior surfaces of a tank containing the process liquid. Transducer attachment techniques favor attachment to metals like stainless steel. What if the chemistry to be used …
Earlier blogs have shown how difficult and deceptive it can be to relate energy consumed to work delivered. In this blog I would like to offer an example of this difficulty as it relates directly to ultrasonic transducers and cleaning. First of all, most (if not all) ultrasonic devices used for cleaning utilize a number …
Most surfaces that we encounter in industrial cleaning are relatively smooth and contiguous. We have talked earlier about the difficulties of cleaning blind holes, threads, capillary spaces and other challenging configurations. The one surface we haven’t yet explored is that of a material that is itself porous. Sintered materials including metal, ceramic, glass, plastic and …
