What are the Main Factors That Affect Defoamer Performance?
There are many cases when there might be the formation of a layer of foam on top of industrial fluids during a process. A defoamer is a reagent that removes any foam on
the
liquid.
These
defoamers
are
also
called
anti-foaming
agents.
The defoamer or anti-foaming agents manufacturers use specific additives to give it such properties. The most commonly used additives to the industrial fluids that act as foam-removing agents are polydimethylsiloxanes and other silicones, stearates, glycols and insoluble oils, and certain alcohols.
Different Types of Defoamer for Chemical Industries: The defoamer chemicals are classified into various categories as mentioned ahead:
#1. Oil-based defoamers: Oils remove foam better than any other substance. Thus, oil-based defoamers have an oil carrier and are usually used more often. The oil carrier might be mineral oil, white oil, or any other oil that is insoluble in the foam apart from the silicone oils.
#2. Water-based defoamers: These defoamers are oil- and wax-based defoamers that can be dispersed in a water base.
#3. Silicone-based defoamers: Silicone-based defoamers are polymers with a silicone backbone (or a similar structure) applied during the foaming chemical process. Polymer defoamers increase foam stability by reducing its tendency to degrade in scorching environments and reducing the amount of water lost to evaporation.
The essential factors affecting the performance of defoamers: #1. The dispersion of the defoamer or the anti-foaming agent affects its performance. Having a suitable degree of distribution and appropriate size of the particle for better performance of the defoamer. #2. The temperature of the defoaming agent affects its performance on a vast scale. It is always recommended that if the temperature of the liquid on which the defoamer should be applied is quite high, then the defoamer’s temperature should also be relatively high. Similarly, on liquids of lower temperature, the temperature of the defoamer should also be low.
#3. Not only in the case of defoamers, but the performance of all objects depends upon their storage. It is preferable to store the defoamers in a cool dark place where the temperature range is between 5oC to 35oC. These were a few crucial factors that affect the performance of the defoaming or anti-foaming agents. But how should we check the quality of a defoamer? Most people and industrialists know that the production of phosphoric acid produces a considerable amount of foam and gases. So, a defoamer for phosphoric acid production which can efficiently prevent and remove all the foam is good in quality. Conclusion: NAQ Global is one of the most trusted and reputed brands supplying industrial products such as chemical fertilizers and even defoamers for phosphoric acid. If you are in search of defoaming agents as such for some industrial purposes, then NAQ Global is the best brand you should refer to. They would provide you with quality defoamers, and their phosphoric acid defoamers are also quite impressive in quality and efficient in performance. NAQ Global also provides filter aid powder, A filter aid powder is an efficient industrial product with many uses, such as processing wastewater, and is also used as an anti caking agent for fertilizers. Like defoaming agents, these filter aid powders are also comprised mainly of silica and are primarily used in food processing and chemical and pharmaceutical industries.
