Titre : Dispersing without grinding media Type de document : texte imprimé Auteurs : Sven Hoffmann, Auteur ; Michael Schmidt, Auteur Année de publication : 2015 Article en page(s) : p. 72-74 Langues : Anglais (eng) Catégories : Dispersions et suspensions -- Appareils et matériels Index. décimale : 667.9 Revêtements et enduits Résumé : The Business Unit Grinding & Dispersing, one of three business units of the global NETZSCH Group, offers a comprehensive program for the many challenges in mechanical process engineering. Here the Business Unit is primarily involved in the areas of wet and dry grinding, mixing, dispersing, deaeration and classifying. The laboratory- and production-scale machines, as well as complete production lines, are used in almost ail areas of industry, such as the future-oriented nanotechnology sector, the production of ink, minerals or foods. The bundling of processing know-how, our extensive machine program, solutions for customer-specific problems and our global presence are unique and hence the strength of the business unit.
A crushing or dispersing process is required in the manufacture of many different products. For some applications with the goal of achieving deagglomeration, disaggregation or delamination, manufacturing technologies are often applied for which optimization is both desired and necessary. With the new OMEGA technology from NETZSCH-Feinmahltechnik GmbH, optimization is often possible for such applications in terms of power requirements, output and service Iife of the machine as well as ease of cleaning and operation.
The function of this machine is similar to that of a high-pressure homogenizer. Due to the unique modular construction of the dispersing unit, the essential difference is that the OMEGA operates with a maximum pressure of only 700 bar. Thus, compared to agitator bead mills or high-pressure homogenizers, a savings in specific energy of more than 50% can be achieved for some applications.Note de contenu : - Comminution processes : true comminution and dispersing

TalcIndex. décimale : 668.4 Plastiques, vinyles Résumé : Many industries are currently seeking to reduce the weight of the end-products they manufacture by using either lightweight components or less material. Thermoplastic foams, such as polypropylene (PP) and polystyrene (PS) foams, are lightweight materials par excellence. These foams can be made even lighter and stronger by using micro-lamellar talc as a nucleating agent. Note de contenu : - Influencing cell structure and reinforcement

OutillageIndex. décimale : 668.4 Plastiques, vinyles Résumé : Tool and mold makers are detail oriented and innovative, but communication of their expertise is not exactly their greatest strength. Furthermore, a tool maker often no longer has the opportunity to communicate directly with his or her actual customer. Material processing intermediaries are increasingly brought in as communication partners between the tool maker and the OEM. The tool maker operates within a jungle of trends, innovations, and anonymous business triangles. Prof. Thomas Seul and Fabian Diehr therefore met with some industry players to explore different paths they have taken through the thicket of this industry-jungle.
