Industrial Disperser for High Performance Paints and Varnishes

An industrial disperser for paints and varnishes is equipment that uses a high-speed impeller to disaggregate clusters of solid particles (pigments) in a liquid medium, creating a homogeneous suspension. It is essential to guarantee the quality and stability of colors and brightness in products such as paints and varnishes.

The main difference lies in the intensity of the energy applied: a disperser, such as the Hydraulic Elevation Disperser, applies high shear energy to disaggregate pigment agglomerates and reduce particle size. A mixer, such as the Multifunctional Agitator, focuses more on homogenizing liquids and maintaining solids in suspension, with lower shear energy.

The choice of impeller is crucial, as its design (e.g. Cowles type, saw teeth) determines the efficiency of shear and product circulation. Specific impellers, such as Agimix's Impeller Accessories, are optimized to create the forces necessary to deagglomerate and moisten pigments, directly influencing the fineness of the grind and the quality of the dispersion.

The main benefits include obtaining more intense and uniform colors, greater brightness, better opacity, increased ink stability (reducing sedimentation), and optimization of process time. A good disperser guarantees the reproducibility of batches and the consistency of the final product.

Yes, many industrial dispersers are versatile and can be used for different formulations, especially those equipped with frequency inverters for speed control and quick impeller change options. However, to optimize the process, it may be necessary to adjust the speed and type of impeller for each viscosity and composition.

For high viscosity varnishes, look for a disperser with high engine power, structural robustness and the ability to operate with impellers that generate strong shear and good circulation. Models such as the Intensive Dispersor Mixer are ideal, as they are designed to handle denser products and ensure effective dispersion.

Safety is guaranteed through stable hydraulic lifting systems, safety guards for moving parts, emergency buttons, and, in environments with flammable solvents, explosion-proof motors and electrical components (Ex classification). Agimix designs its equipment, such as the Dispersor with Hydraulic Elevation, with a focus on operator safety and compliance with standards.

The grinding fineness is a critical indicator of the quality of pigment dispersion. Inadequate fineness can result in paints with low color intensity, poor gloss, grainy texture, rapid sedimentation and lower hiding power. Efficient dispersers ensure particle size reduction to the levels required by the application.
