Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book presents a novel and practical instrument for measuring the air permeability of paper and other sheet materials with remarkable precision. It is a significant advancement compared to existing airflow meters with limited ranges and prone to leakage errors. The book traces the development of the instrument, detailing the author's journey in addressing the shortcomings of available devices. The design process involved overcoming challenges in preventing edge leakage, maintaining constant pressure, and accommodating a wide range of permeabilities. The author introduces the concept of a "double-flow" meter arrangement, which was crucial in achieving precise measurements. The instrument's design also addresses the issue of leakage by employing a unique cell structure that effectively isolates the test area, preventing air movement outside the intended path. The book emphasizes the meticulous attention to detail in constructing the permeability cell and ancillary apparatus. It highlights the significance of calibrating the instrument against known standards to ensure accuracy. The author provides tables for capillary coefficients corresponding to pressure differences, facilitating straightforward calculation of air permeability values. The instrument described in this book has broad applications beyond paper testing. It can measure the permeability of leather, textiles, and various sheet materials. The author explores the potential of the instrument in studying the structure of paper, aging effects, and the behavior of materials under different conditions. This book's insights advance the field of permeability measurement and offer valuable tools for research and quality control. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9780266010067_0
