Bell Mouth Plastic Disposable Static Mixer

The mixer attach to the Dispensers. The patented mixer keep parts A and B of the adhesive separate until they meet inside the mixing tips. As a result of this design, the static mixer prevents cross contamination and curing of the A and B components at the interface (Where the dispenser and static mixer connect. )This eliminates the common unwanted curing problems that typically occur at that interface when using traditional meter, mix, and dispense equipment.

A static mixer is a device for mixing two fluid materials. Most commonly, the fluids are liquid; However, static mixers are used to mix gas streams, disperse gas into liquid or disperse immiscible liquids. The device consists of mixer elements contained in a cylindrical (tube) or squared housing. These can vary from 6 mm to 6 meters diameter. Static mixer elements consist of a series of baffles that are made from metal or a variety of plastics. Similarly, the mixer housing can be made from metal or plastic. Typical materials of construction for the static mixer components included stainless steel, polypropylene, Teflon, Kynar and polyacetal.

The overall system design incorporates a method for delivering two streams of liquids into the static mixer. As the streams move through the mixer, the non-moving elements continuously blend the materials. Complete mixing is dependent on many variables including the fluid properties, tube inner diameter, the number of elements, and their design.

A static mixer is a series of fixed, typically helical, elements enclosed within a tubular housing. The fixed geometric design of the unit can simultaneously produce patterns of flow division and radial mixing.
Flow Division in a static mixer is a function of the number of elements in the mixerFlow Division: In laminar flow, a processed material divides at the leading edge of each element of the mixer and follows the channels created by the element shape.

At each succeeding element, the two channels are further divided, resulting in an exponential increase in stratification. The number of striations produced is 2n where 'n' is the number of elements in the mixer.
Radial Mixing: In either turbulent or laminar flow, rotational circulation of a processed material around its own hydraulic center in each channel of the mixer causes radial mixing of the material. Processed material is intermixed to reduce or eliminate radial gradients in temperature, velocity and material composition.

Applications
Today static mixers are established in many different market segments and are used for a wide range of different applications [1]A common application for static mixers includes mixing two component adhesives (e. G. Epoxy) and sealants (see Resin casting). Other applications include wastewater treatment and chemical processing. [2] Static mixers can as well be used in the refinery and oil&gas market for example for the desalting of crude oil. In the polymer production static mixers can be used for polymerization reactions or for the admixing of liquid additives.
