Question: We need to disperse a powder in the liquid phase to below 1 micron. We found high-shear emulsifiers and homogenizers on the Internet. I don’t know the difference between the two. They are better than ordinary high-speed mechanical stirring. The good thing is, which one should we choose, please explain why.
Answer: The homogenizer is mainly used to mix two liquid substances with better effect, but it is not suitable for mixing solid and liquid substances. Because the homogenizers are mostly plunger type, solid particles will wear the plunger, and the particles will get stuck at the one-way valve, reducing the homogenization effect.
