Automation in coatings production / Klaus-W. West / Hannover [Germany] : Vincentz Network GmbH & Co. (2020)    

Titre : Automation in coatings production Type de document : texte imprimé Auteurs : Klaus-W. West, Auteur ; Christoph Fleischer-Trebes, Auteur ; Natalie Schwerdtfeger, Auteur ; Hans Joachim Jacob, Auteur ; Peter van den Berg, Auteur Editeur : Hannover [Germany] : Vincentz Network GmbH & Co. Année de publication : 2020 ISBN/ISSN/EAN : 978-3-7486-0259-0 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Automatisation Production Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : While the automation of processes in many areas ensures higher efficiency and safety, the question arises how this affects the coatings industry. This eBook shows what is already automatable and how the coatings industry can learn from other branches of industry to help make the working days more efficient and future-ready. Peter van den Berg and his team have already embraced this aspect of automation by using not only a 3D printer to make disposable applicators but also a robotic interface to automate the inspection process in the paint production and so substantially reduce its carbon footprint. Klaus West examines whether digitization and simultaneous automation in the chemical and pharmaceutical industries jeopardize jobs, how these are changing and what skills we will need to acquire today to safeguard future careers. All in all, this eBook is a compilation of different, trend-setting articles regarding e. g. the important role of planning in the development of new paint-making systems, a consistent product quality in a fully automated, continous coating production or process adjustments in dispersing pigments and fillers.

Dispersing without destroying / Hans Joachim Jacob in SOFW JOURNAL, Vol. 145, N° 5 (05/2019)

[article]  inSOFW JOURNAL > Vol. 145, N° 5 (05/2019) . - p. 34-37 Titre : Dispersing without destroying Type de document : texte imprimé Auteurs : Hans Joachim Jacob, Auteur Année de publication : 2019 Article en page(s) : p. 34-37 Langues : Anglais (eng) Catégories : Dispersions et suspensions Expansion sous vide hydrocolloïdes Rhéologie Index. décimale : 660.2 Génie chimique Résumé : In home and personal care products, many hydrocolloids are used as thickeners and rheological additives. When mixed into liquids, initially agglomerates are created, vvhich then have to be broken dovvn again through dispersing. However, most of these polymers are shear sensitive, especially after hydration. Dispersing destroys the gel structure already formed and breaks down the desired viscosity. This problem can be solved with a process that separates the primary particles of the polymer powder before they get in contact with the liquid, then individually wets and disperses them immediately, thereby hydrating them without agglomerates — using the vacuum-expansions process. It is based on the fact that a powerful vacuum is generated directly in the liquid. The polymer is therefore added under maximum vacuum. In this way, the polymer particles are dissagglomerated before wetting. No further dispersion is required. Agglomerates are not created. Using the vacuum expansion process, the maximum effect can be achieved with a reduced concentration of hydrocolloids. Viscosity, thixotropy index, transparency, film formation and wetting behaviour, as well as many other properties this way will achieve a level not possible previously A subsequent uncontrolled thickening through inorganic thickeners, such as smectite or other layered mineral silicates is ruled out.

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 3 (03/2019) . - p. 138-143 Titre : Keeping distance : Dispersing under vacuum expansion creates paints and lacquers with high colour strength. Less titanium dioxide is necessary because of more efficient dispersion by the new technology Type de document : texte imprimé Auteurs : Hans Joachim Jacob, Auteur Année de publication : 2019 Article en page(s) : p. 138-143 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Couleur Dioxyde de titane Dispersions et suspensions Granulométrie Opacité (optique) Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : Titanium dioxide (TiO2) is one of the main cost drivers when producing paints and lacquers. Currently around seven milliontonnes of TiO2 are produced per year. The global market price per ton has increased by around 50 percent on average over the last few years - for high qualities it almost doubled. A new technology combines in-line dispersing technology together with a vaccum expansion method in order to use TiO2 more efficiently.
