What Are Static Mixing Nozzles?
Static mixing nozzles, also sometimes referred to as static mixer tubes or static mixing tips, are a dispensing tool for two-part adhesives that use stationary components called elements to mix the two parts together into a homogenous mixture as they make their way down the chamber before being dispensed. This mixing process often activates the adhesive or material being dispensed and begins the adhesion process.
Static mixers attach to hand-held or meter mix dispensing equipment and are designed to be thrown away after each use. Their composition, including their number of elements, length, tip, and cartridge compatibility, can vary greatly depending on the needs of the application. There are also many different brands of static mixers. Several have similar or almost identical compositions, but in some cases, a brand will have a unique design.Consequently, understanding and choosing the right mixer can be challenging, but we want to help by breaking down the different components and offering some product recommendations.
Types of Mixing Elements
Mixing elements are the stationary structures found inside that mixer that are used to blend and mix the two components together as it is pushed through the nozzle. These elements can come in several designs.
Helical mixing elements - The traditional setup, helical elements have alternating orientations for a spiral-looking design and round nozzle.
Quadro mixing elements - Quadro or square mixing nozzles are growing in popularity. They have a square shape grid design and require a shorter distance to provide the same efficient mix.
While these two designs are the most common, some brands have created their own style of mixing elements that can include a combination of the two or other geometric designs.
Disposable Static Mixer Connection Types
There are a number of different ways to connect a disposable static mixer to your cartridge or meter mix equipment. The most common static mixer inlet types are bell, bayonet, and integral nut.
Bayonet Connection - This rectangular connection is a twist and lock setup that is common for cartridge glue guns of all sizes.
Bell Connection - This type of static mixer connection will attach to a glue gun or more commonly, meter mix equipment using a retaining nut. After the nozzle is attached, the nut will slip over the top and screw into the equipment or gun.
Integral Nut (Threaded) - Typically used for larger cartridge sizes, these static mixer connectors have a threaded end that can be screwed directly onto the cartridge without the need for a retaining nut.
Some brands have their own connection types. The Sulzer (Medmix) B system and F systems, for example, are generally not compatible with other systems.
Types of Disposable Static Mixing Tips
There are also several different static mixer tips to fit different dispensing needs. The three most common mixer outlets are stepped, tapered, and Luer lock.
Stepped Tip - These tips can be cut at various points to increase the size of the adhesive bead being dispensed. The ends don't require any adapters or needles to adjust bead size. The downside comes when fine dispensing is required.
Tapered Tip - Tapered tips are not adjustable, and for the most part, will not accept needles or fine tips. This is a simple and easy way to dispense common bead sizes.
Luer Lock - Luer lock tips give users the ability to add adhesive needles or tips for precise dispensing. Often, this type of disposable nozzle style requires an adapter like the Sulzer Mixpac LA 05-00 Luer lock adapter. After the adapter is attached, the needles and tips can easily be locked into place.
Full Bore - With a wider opening, a full-bore outlet is ideal for high-viscosity materials.
Choosing the Right Type of Mixer
You want to ensure that you get the right mixer for your specific requirements. The type of static mixer nozzle you need will depend on a number of different factors.
Type of Connection - Different cartridges and dispensing equipment use different connectors. Users should always start with the type of connection required.
Dispensing Equipment - One key consideration is if the adhesive will be dispensed by a machine or a hand-held applicator. Disposable mixers are more frequently used for hand-held equipment and are compatible with various cartridge sizes. Machine dispensing applications may also use static mixers if adhesives are being changed or other mixing options aren't feasible.
Type of Material - The materials you are mixing help determine the number of elements needed. Some materials are considerably more difficult to mix than others, so they require a higher number of elements in your mixer. The mix ratio of the material will also impact the number of elements required to achieve a homogenous mix.
Viscosity - Thicker adhesive components require larger diameter openings to flow and mix properly. The difference between component viscosities will also affect the number and type of elements needed. If the two elements have very different viscosities, you will likely need to use a higher number of elements.
Shot Size - A larger shot size/faster dispensing will require fewer mixing elements and a larger diameter opening. Because a larger diameter usually means less efficient mixing, a balance is required between the two. Smaller shot sizes require more mixing elements and a smaller diameter for an ideal mix.
Size - You will also need to figure out what size cartridge or meter mix equipment you will be dispensing from. This will help determine what type of mixer nozzle you need.
