How does it work?

The SpeedMixer DAC 150.1 FV works by spinning a high speed-mixing arm in one direction while the basket rotates in the opposite direction (thus, the name - Dual Asymmetric Centrifuge). This combination of forces in different planes enables incredibly fast mixing, and yet the precision construction of each machine gives it a balance that allows amazingly quiet operation.

What can it do?

With this instrument, the typical mixing time for fully dispersing a colour paste in a silicone sealant is less than 10 seconds; for mixing fumed silica or precipitated chalk silicone formulations 8 - 14 seconds will normally suffice. These are both operations that would otherwise require 3 hours or more of mixing time, and they can only be done in quantities of 1 quart or greater. Mixing never incorporates air and additional mixing time removes air from the blend, yielding a finished product when the mixing process is done. Fluids of widely differing viscosities can be blended quickly.

What materials can it mix?

The SpeedMixer DAC 150.1 FV is useful for 1 and 2 part silicones, polyurethanes,
polysulfides, acrylics and a wide range of other materials. There are certainly a great number of products not included in this list that can benefit from the use of the SpeedMixer technology. With disposable cups, there is no worry about contamination in colour master
batches, pharmaceutical products, or other sensitive materials, since the DAC 150.1 FV has no mixing components to clean. Both re-usable and less expensive disposable cups (recommended especially where crosscontamination is a problem) are available. The Speed Mixer DAC 150.1 FV also allows the use of higher filler loadings than conventional
mixers, e.g., 25% or more of fumed silica into a silicone!

How much can it mix?

The maximum batch weight that can be mixed is 100 grams, (150g total, including the mixing cup, lid, and holder). Cups are used with holders that have weights designed to maintain the balance of the machine. Various cup sizes are available (Max 10, 20, 40, 60 and 100 gram) to meet your needs and minimize material waste by tailoring the actual batch size to the quantity you need, not what the mixer requires. For larger sample quantities up to 300g - the DAC 400 Range is now available.

Where is this instrument used?

The main current applications are for lab screening of development formulations and formulation components, for QA testing, and for small volume production. The incredible speed of mixing / grinding allows a complete sealant, coating, plastisol, or adhesive batch to be made in less than 5 minutes! The bottleneck now becomes the weighing operation, not the mixing / grinding. This makes every SpeedMixer™ user a better compounder, since it allows the mixing of many iterations that would otherwise go untested due to time constraints. The SpeedMixer DAC 150.1 FV has proven itself extremely useful for tests involving cure rates, colours , and appearance, as well as the measurement of basic physical properties. This permits the screening of numerous formulations before the next phase of development scale-up. SpeedMixer technology involves using the proper cup for each mixture to be run.

How do I control the instrument speed to avoid damage to my product?

Especially designed for research and development work, the DAC 150.1 FV has variable speed (300 - 3500 rpm, set by the revolution rate) and a window for viewing the mixing basket, allowing more in-depth research work to be done. The speed is adjusted by simply turning the control dial. Additionally, fixed speeds can be set using the keyboard and by –pass the speed control dial - in order to carry onut a series of batches at a desired speed. Using lower speeds can help avoid some of the effects of the tremendous centrifugal forces generated at top speed, e.g., the build-up of frictional heat in sensitive mixes, or the potential damage to microenvironments.n
