The disadvantages are as follows: because the static mixer is internally provided with no moving part and cannot realize high-speed stirring through a mechanical structure, when the proportion of two kinds of glue is too large, the glue can be mixed unevenly, and the chemical reaction is insufficient.

2. Dynamic mixer: the dynamic mixer mainly comprises a mixing cavity and a mixing vibration stirring paddle. The basic working mechanism is that the motor drives the vibrating stirring paddle to rotate at a high speed to mix two kinds of glue in the stirring cavity, so that the purpose of mixing the two kinds of glue is achieved.

The disadvantages are as follows: because the dynamic mixer has moving parts, the moving parts need to be sealed to prevent glue leakage, but some special glues contain sand grain-shaped filler components with high hardness, and after the mixer works for a period of time, sand grain-shaped particles can slowly infiltrate between the dynamic sealing body and the static sealing body, and finally, the seal is worn, failed and leaked.
