Overview
The ROSS White Paper on "Mixing Technologies for the Production of Low to High Viscosity Adhesive Applications" discusses the essential role of effective mixing in the adhesive manufacturing process. It emphasizes that the quality of mixing equipment and methods significantly influences processing efficiency and the final product's quality.
The paper highlights the evolution of mixing technologies, particularly the transition from traditional low-speed agitators, such as propeller and turbine mixers, to advanced High Shear Mixers (HSM). These modern mixers are crucial for preparing stable emulsions of adhesives, polymers, and resins. Traditional methods often required long mixing times, sometimes up to 24 hours, which were inefficient and labor-intensive. In contrast, ROSS HSMs can achieve desired product characteristics in significantly shorter times, as demonstrated by a case where a manufacturer reduced mixing time from one hour to a single pass.
The document also introduces the SLIM (Shear-Layer Induction Mixer) system, which allows for the immediate incorporation of solids into liquids, preventing agglomeration and ensuring rapid dispersion. This system has proven advantageous over older dispersion mills by offering lower processing temperatures, higher solids loading capabilities, and faster powder induction.
Additionally, the paper discusses the importance of testing and development in the adhesive industry. It describes a scenario where a manufacturer of trowellable adhesives faced challenges in scaling up production for a new product line, underscoring the need for efficient mixing solutions in meeting production demands.
Overall, the white paper serves as a comprehensive overview of contemporary mixing technologies, showcasing how innovations in mixing equipment can address common challenges in adhesive production, ultimately leading to improved efficiency and product quality in the industry.
