Some applications require two-component structural glue for better performance and results. It’s more reliable than conventional glue, but it needs special tools, such as static mixing nozzles, to manufacture. When used with static mixing tubes, the nozzles simplify the creation of two-component structural glue in a particular ratio to make the adhesive ideal for sticking large load-bearing materials.
Their significance in making better adhesives
Single- and two-component glue products typically come with different systems when the glue is involved. The latter consists of components A and B. Before use, they must be mixed to a specific ratio using a static mixing nozzle. External forces don’t affect the static mixing tube as only the fluid is used through the mixer for continuous cutting and reunification until the components result in a uniform mixture.
Automatic coating equipment typically requires round mixing tubes, and manual gluing may consider round or square tubes. The choice ultimately depends on the unique requirements for making the adhesive and its purpose.
Features to consider
Static mixing nozzles, are classified according to their form. Here’s an overview of each:
Bell mouth: This mixing nozzle suits 200ml and 400ml AB glue guns. It can also function with a two-component liquid mixing machine.
Bayonet: Most static mixing nozzles are spiral or bayonet-type. The working principle is after the glue comes out from rubber hose A and rubber hose B flows through the tube. It can be cut, remixed, rotated, and sheared by a spiral blade several times before it’s divided into several small parts. A spiral blade makes the glue flow rotate to the left or right to change the direction of the flow. This way, the central fluid goes to the periphery, and the surrounding fluid can move to the center for an adequate liquid mixing effect.
Twist Lock-type: These static mixing nozzles are for new 50ml glue guns. They come in different types to suit specific glue mixing ratios, such as 10:1 and 1:1. They can replace mixing tips like DP100, 3819, 08115, 08193, and 08194.
Get the right nozzles.
Static mixing nozzles must be based on standard usage specifications. These are consumables, so they require regular replacement. A handheld branch adhesive can be mixed automatically in every component’s correct volume ratio. In general, a uniform color distribution determines a homogeneous mix. The adhesive should cure quickly after mixing.
