To equip a paint line for surface treatment with a fully automated dry ice blasting unit, including a robot and dry ice granulate production, can increase the profitability. Note de contenu : - Space-saving integration into the painting line - Dry ice production as required - FIGURES : 1. Dry ice : the extruded strands are cut into granules and crushed into 1 to 1.5mm ice particules in the nozzle of the blasting applicator before compressed air accelerated them to supersonic velocity - 2. Demand-driven dry ice production : the supply and pelletizer unit of the dry ice blasting system is placed in the area of the paint supply and thus allows a continuous blasting process - 3. Easy dry ice cleaning : the robot, with was unsed only for flaming till now, was additionally equipped with a CO2 supply and a blasting applicator - 4. Automatic selection of the part-specific cleaning program : because the Combi 120H is integrated into the painting line, the shift manager only needs to enter component type and color En ligne : https://drive.google.com/file/d/17nAvMt2cwU94IM7QJwmONtvFCM03uf9I/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29122 [article]

Influence of chain length of organic modifiers in hydrophobization process on epoxy resin properties / G. Morgiante in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 19, N° 4 (07/2022)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 19, N° 4 (07/2022) . - p. 1045-1053 Titre : Influence of chain length of organic modifiers in hydrophobization process on epoxy resin properties Type de document : texte imprimé Auteurs : G. Morgiante, Auteur ; M. Pilkowski, Auteur ; J. Marczak, Auteur Année de publication : 2022 Article en page(s) : p. 1045-1053 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Adhésion Angle de contact Caractérisation Eau Energie de surface Epoxydes Glace sèche Matériaux -- Modifications chimiques Mouillabilité Mouillage (chimie des surfaces) Revêtements organiques Index. décimale : 667.9 Revêtements et enduits Résumé : Resins have been widely used in a variety of industry fields for more than a century, such as coatings, adhesives, or automotive. Their low cost and workability are extremely useful in creating more and more advanced materials due to their chemical structure (Ghaffari et al. in Surf Interfaces 17:100340, 2019). Common problem today is the wetting tendency of various materials which in the end can result in further damage in the structure because of atmospheric conditions. Nowadays, scientists are trying to find better ways to improve the properties of coatings or composites in cases like hydrophobicity or icephobicity. One of the examp les are fluorinated organic compounds with good linking properties to the substrate (Qin et al. in Mater Today Commun 22:100770, 2020). Because o f that, to im prove the properties of a basic epoxy resin, its chain has been modified with hydrophobic compounds with different chain lengths. Influence of modifiers’ molecule size on hydrophobic and ice adhesion properties of obtained epoxy resins has been tested. Chemical composition of prepared coatings was analyzed by FTIR. Moreover, their thermal stability was investigated using TG and DSC measurements. Additionally, wettability of the samples was analyzed with a goniometer. Furthermore, their ice adhesion tests were performed on a dedicated apparatus. As a result, presented work provides a critique overview and concept of promising icephobic and hydrophobic coatings in the industry. Moreover, these products have a high chance to be developed further.
