4. Metal powder inks
5. Plastic flexible packaging inks (partial high viscosity systems)1. Suitable for high-viscosity materials
Some special inks (such as screen printing inks, ceramic inks, and metal inks) have viscosities as high as millions of cP, and ordinary dispersing equipment cannot effectively stir them. In this case, the strong shearing and compression mixing effects of the sigma mixer are particularly important.
2. Dispersion and mixing are completed simultaneously
Sigma mixer can simultaneously complete the uniform mixing and fine dispersion of pigments, fillers adn binders (such as resins and oils), thereby improving the coloring power and gloss of the pigments.
3. Closed mixing environment
Sigma mixer can be designed as a vacuum type or a closed structure to prevent solvent volatilization, which is beneficial to environmental protection and safety, and is especially suitable for the production of inks with high requirements for odor and solvent loss.
4. Temperature control system
During the production process is ink, some systems will heat up. The jacket of sigma mixer can pass cooling water or heat transfer oil to effectively control the material temperature and avoid degradation of heat-sensitive materials.
