Download or read book Conception des pi ces plastiques inject es written by CHARVOLIN Jean-Luc and published by Lavoisier. This book was released on 2013-09-01 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alors que les matières plastiques n’ont été découvertes qu’il y a peu de temps, elles sont devenues indispensables à nos modes de vie. Pourtant, la « culture plasturgie » est encore peu répandue et les différents corps de métiers manquent d’un langage commun. L’auteur présente dans l’ouvrage, sous forme de guide, les éléments essentiels à la compréhension de tout le processus, du cahier des charges à la fabrication, en incluant la conception et la réalisation de moules. Conception des pièces plastiques injectées débute par une histoire des matières plastiques, complétée par une présentation des matières plastiques (composition, origine, polymérisation). L’ouvrage étudie ensuite l’injection des polymères, la conception des moules, le prototypage et l’usinage des pièces et des moules. Il expose également les défauts de pièces, les méthodes d’assemblage des matières plastiques et la décoration. Enfin, le dernier chapitre propose un exemple d’utilisation d’outils de simulation. Cet ouvrage s’adresse aux responsables et concepteurs en bureaux d’étude pour pièces plastiques et moules, aux responsables techniques et régleurs sur presse à injecter. Il intéressera également les professeurs de physique-chimie, de technologie en IUT et BTS, les enseignants de chimie et matériaux dans les universités et écoles d’ingénieurs et enfin les étudiants en plasturgie, chimie et matériaux.

Available in PDF, EPUB and Kindle. Book excerpt: Ce livre est destiné aux étudiants et aux techniciens et ingénieurs concernés par la transformation des matières plastiques, le choix des équipements ou la conception des pièces et outillages.Il propose une approche pragmatique et détaillée, résolument orientée process, des problématiques rencontrées dans l'injection des matières plastiques. La description du procédé précède les bonnes pratiques de réglage permettant d'obtenir un process stable et optimisé. La compréhension des principaux phénomènes débouche sur la résolution des problèmes d'injection. L'étude des paramètres machines permet de définir le cahier des charges de la presse adaptée. L'examen de la conception des moules du point de vue de la stabilité et la performance du process permet d'optimiser les outillages. Le triptyque procédé- produit- matériau guide les considérations sur la conception des pièces.La réflexion sur les caractéristiques du polymère ou du compound débouche sur les aspects process et les bonnes pratiques orientées vers la stabilité du process

Download or read book Chemistry of Lignocellulosics written by Taylor & Francis Group and published by CRC Press. This book was released on 2021-03-31 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the chemical properties of lignocellulosic fibers, knowledge of which is essential for innovation and sustainable development of their transformation. Thermochemical transformation of wood and other lignocellulosics is presented to highlight its volatile, liquid and solid products and their novel applications. Forest biorefinery is described to emphasize the new products from lignocellulosic constituents, both structural (cellulose, hemicelluloses and lignins) and those extraneous to cell walls-extractives. New developments in cellulose technology related to nanocellulose are discussed in relation to new applications. Industrial lignins are presented in detail, both in terms of extraction procedures from spent liquors and structural characterization of the isolated lignins. Application of lignocellulosic biopolymers in new composite materials, or in biomaterials for medicinal purposes, and in solid wood preservation, are described. The example of an industrial biorefinery installed in southwestern France more than 40 years ago is presented.

Download or read book Unidentified written by Robert Salas and published by Career Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1969 the U.S. Air Force issued a statement that read' "No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security." This statement is patently false. It has been proven untrue by the testimony of many military officers and airmen and documentation of incidents involving UFOs and nuclear weapons, testimonies of which the U.S. Air Force was fully aware. Unidentified details many of these testimonies, some for the first time. As partial justification for its position, the Air Force cites a University of Colorado study that was contracted and paid for by federal funds. Unidentified reveals how this study was actually just another part of the plan to cover up the reality of the UFO phenomenon. For the first time, Unidentified publishes evidence that the investigators for the Colorado study knew about the UFO-related missile shutdown incidents but did not investigate them or include them in their final report.

Book excerpt: An Apollo 11 astronaut and the Nebula Award–nominated author of Directive 51 present a novel that “conveys the wonder and promise of space” (Publishers Weekly). Born the year of the Moon landing, Chris Terence spends his life fighting to return humanity to that pinnacle. An engineering student with dreams of spaceflight, he finds upon graduation that the United States no longer has need for astronauts. Years of bureaucratic meddling have reduced the space program to a shell of itself, and it will take the greatest scientific find in history to send humanity skyward once more. After years battling budget hawks, Chris finally gets his chance to walk on the Moon. While there, he finds evidence of an ancient alien civilization, the Tiberians, who visited Earth’s satellite eight thousand years before. Understanding what happened to those long-forgotten travelers will define the lives of Chris and his son, as they fight against all odds to unlock the secrets of the universe. “The collaboration of the first man to pilot a moon lander (Aldrin) with a major voice in contemporary science fiction (Barnes) has produced a fascinating chronicle of man’s first encounter with alien intelligence” (Booklist).
