In addition, the streamline design and gradually widening cross section of the dispersion blades 21 help to optimize the fluid dynamics performance and reduce flow resistance, thereby improving the dispersion efficiency.
[0051] It should be noted that the number of dispersion blades 21 is not limited to two, and the number of dispersion blades 21 is configured according to the size of the two-component polyurethane stirring and spraying equipment.
