Heat – A Balancing Act

We all know that temperature is an important parameter in cleaning and cleaning-related processes.  Too little and cleaning will be ineffective.  Too much can lead to possible chemical separation, part degradation and loss of ultrasonic cavitation.  So providing the proper temperature is mandatory for the best cleaning result.  Sounds easy?  Well, yes and no – consider …

Chemistry – Automated Chemical Metering Devices

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 …

Potential Process Problems NOT Related to Cleaning

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 …

Chemistry – Automatic Chemical Makeup

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 …

Chemistry – More Ways to Measure Chemical Concentration

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.  …

Chemistry – Measuring Cleaning Chemical Concentration

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 …

Chemistry – What is Titration?

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 …
