Previous blogs have revealed a number of ways to measure chemical concentration in a cleaning bath. It is a logical extension that process engineers utilize these tools to automate maintaining the proper chemical concentration in their cleaning processes. Overall, this is a great idea. However, there are some pitfalls and things that should be taken …
So far, we have recognized pH and specific gravity as ways to determine chemical concentration in cleaning solutions. This blog will explore additional techniques that may also be used for this purpose. Conductivity – Pure water is a poor conductor of electricity. As chemistry is added to water, it’s ability to conduct electricity is increased. …
In order to maintain process consistency in an industrial cleaning process, it is frequently necessary to monitor the concentration of chemistry in a cleaning solution. pH and specific gravity are two common parameters that can be used to determine the concentration of cleaning chemistries in water. This blog explores ways in which pH and specific gravity can …
With this post, I have reached 200 in what may be an infinite series of blogs. So far, it has been a very interesting adventure – not only because I’ve been able to share a lot of information with you people who read this blog but because I’ve learned as well. Having been in the …
Titration is a procedure frequently used to measure the chemical concentration in a liquid. The concept is pretty simple. A specific volume of the solution under test is collected and put into a container which is usually an erlenmeyer flask or a beaker. The container can be glass, plastic or another material. Glass is often preferred because …
In a preceeding blog, I mentioned that pH is a logrhythmic function. As such, each increase of one pH unit represents a ten-fold change in the measured characteristic. This alone can lead to considerable confusion. But it gets worse! Concentration – One would think that pH would be directly related to concentration – – meaning …
Let me preface this blog with a disclaimer – – I am not a chemist. My understanding of the subject of pH is only as it relates to industial cleaning, cleaning chemistries and their application. Over the years, I have been associated with many chemists who have been very helpful in their efforts to advance …
Buffing compound is a material used in polishing operations which must be removed once polishing is complete. Buffing compound consists of a finely divided abrasive mixed with a “vehicle” which is often a paraffin or, in some cases, animal fat and other “fats” depending on their price and availability in a particular region of the world. The “vehicle” …
By law, there must be a Material Safety Data Sheet for any material used in any process. The law was instituted, basically, because workers were unknowingly coming in contact with materials that were dangerous not only from a physical standpoint (fire, reactivity, explosivity, etc.) but to human health and well-being as well. Many of today’s …
