The vacuum disperser integrates a vacuum environment with efficient dispersing and stirring, boasting significant performance advantages. It generates strong shearing force through a high-speed rotating dispersion disc, which can refine and uniformly disperse material particles, effectively avoiding agglomeration, thus achieving excellent dispersion effects, especially suitable for handling suspensions, emulsions, etc. At the same time, it can operate under vacuum conditions, which can effectively remove bubbles in materials, prevent oxidation, ensure product purity and stability, and is particularly applicable to bubble-sensitive materials such as adhesives, coatings, and cosmetics. In addition, it has a wide range of applications, capable of handling various materials from low to medium-high viscosity, including coatings, inks, pigments, ointments, cosmetic bases, etc. Moreover, it features flexible operation, with the dispersion speed adjustable according to needs, meeting the diversified dispersion requirements of different industries.
