Traîtements de surfaceIndex. décimale : 668.4 Plastiques, vinyles Résumé : The Calvasol method provides a flexible, economical, and efficient way to functionalize films with corresponding coatings. Compared to alternative methods, the applied layer thicknesses are in the range of 0.1 to 10 nm which reduces the consumption of chemicals and energy in processing. Note de contenu : - Avoiding high energy consumption for drying
- Treatment and coating in one process step
- Direct integration into the extrusion process
- Further development of functional chemistry
- FIGURES : 1. Schematic representation of the Calvasol method that combines the corona treatment and aerosol application. It is used for the permanent andi-adhesion, antifog or antistatic functionalization of films - 2. The aerosols are applied to the film from below. This has the benefit that the functional molecules can be anchored in a very thin and even layer - 3. The Calvasol system can be integrted directly into the lamination process with no negative influence on the lamination adhesive - 4. Measuring the contact angle of a film coated with and without Calvasol shows the influence of the Calvasol antifog function : The goal is to create a surface with maximum hydrophilic properties, indicated by a small contact angle in the measurement with water. The greater the contact angle (image on the right), the poorer the antifog effectEn ligne : https://drive.google.com/file/d/13hytvqc7_RbMNMMsWKL1MxA45wqXt11w/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28474

Réseaux neuronaux (informatique)Index. décimale : 668.4 Plastiques, vinyles Résumé : A surrogate-based warpage optimization for injection molding is proposed in this study. The optimization process aims at minimizing the warpage of the injection molding parts in which process parameters, i. e., the mold temperature, melt temperature, injection time, packing time, packing pressure, and cooling time are the design variables. The warpage values are reduced by optimizing the process parameters. A new optimization iteration scheme based on artificial neural network (ANN) combined weighted expected improvement (WEI) is employed to speed up the optimization process and to ensure very rapid and steady convergence. The ANN is used to build an surrogate warpage function for the process parameters, replacing the expensive simulation analysis in the optimization iterations. The adaptive process is executed by the WEI function, which is an infilling sampling criterion. Although the design of experiment (DOE) size is small, this criterion can precisely balance the local and global search and tend to find the global optimal design. As examples, a TV cover and a scanner are investigated. The results show that the proposed approach can effectively reduce the warpage of the injection molding parts.
