drying process

This book addresses the challenges faced in the development and manufacturing of functional films, particularly the defects and troubles that often arise. The author, having studied coating theory in a production technology research department and worked as a technician in manufacturing, found that existing literature was overly academic while practical information was often biased towards know-how, making it difficult to grasp essential points. This book is aimed at both beginners and experienced professionals involved in the development and manufacturing of Roll To Roll coating and drying processes. It provides a comprehensive overview of various coating methods, primarily focusing on slot coating, along with gravure, blade, and spin coating techniques. Additionally, it discusses drying methods, including conventional hot air drying and infrared techniques, as well as differences with laboratory hot plates. The book also covers fundamental concepts related to surface tension and viscosity of coating solutions, foreign matter and countermeasures during manufacturing, and cleanroom design affecting functional film quality. By disseminating comprehensive coating technology that integrates theory and practical skills, the book aims to contribute to the advancement of the functional film industry.
