You may have noticed, or not, that many of my blogs are relatively dry and technical. Well a colleague recently encouraged me to lighten up a bit and share with you some images from my recent trip to South Korea. I traveled to Korea to start-up two new Sonolator systems recently purchased by one of our customers.
The Sonolator homogenizer has been used for years to disperse fumed silica into resin. In fact, the Sonolator is so effective that it is mentioned by name in Evonik's literature for their fumed silica product Aerosil. See an image of the Evonik website below:
Dow Corning, a major producer of silicone for the chemical and personal care industries, recommends the Sonolator homogenizer for creating silicone emulsions. Below is an example of one of Dow's "Beauty & Personal Care Solutions" brochure. The Sonolator is called out (see yellow highlight) by name in this brochure discussing formulation tips for Dow Corning 9040 Silicone Elastomer Blend.
Most Colloid Mill manufacturers simply sell Mills off the shelf as is. Most sales staff for these off-the-shelf Mills only know information about the product itself and not much about the surrounding components and instrumentation that might come into play once the unit is on the factory floor. Sonic Corp not only manufactures and sells its Colloid Mills, we specialize in understanding upstream and downstream processes that allow us to customize our systems to meet the needs of the factory floor.
A manufacturer approached Sonic with an application to disperse and de-agglomerate a pigment used to color a plastic part they were manufacturing. The pigment would agglomerate and cause color bursts inside the plastic. While there was no damage to the integrity of the product, however, the color appeared inconsistent and was perceived by the end-user as problematic. Sonic recommended a Colloid Mill for this dispersion application.
Occasionally we receive an inquiry regarding a used Sonolator homogenizer. The client wants to know the specifications for a system built 10-30 years ago. Sometimes we have the records and can provide detailed specifications. Often the unit is too old for our records and we have to provide an educated guess as to the original design. Additionally, it is not unusual to find a listing for a used Sonolator homogenizer system which in fact no longer has the Sonolator homogenizer or mixing element attached and therefore is just a pump and motor.
