一、引言随着远红外烘烤技术的广泛应用,红外线热干燥机理越来越受到普遍重视。目前盛行的理论有“匹配理论”和“非匹配理论”,但有关红外的光化学反应方面的文章还比较少见。油漆烘烤在红外烘烤中占有相当大的比重。从油漆的成膜机理来看,除少数油漆是由于溶剂挥发而干燥外,多数油漆在成膜过程中都伴随着化学反应。由于高分子反应速 I. INTRODUCTION With the wide application of far-infrared baking technology, the infrared thermal drying mechanism has been paid more and more attention. The prevailing theories are “matching theory” and “non-matching theory”, but the articles on the photochemical reaction of infrared are still relatively rare. Paint baking in infrared baking occupies a considerable proportion. From the paint film forming mechanism, except for a small number of paint is due to solvent evaporation and drying, most of the paint in the filming process is accompanied by a chemical reaction. Due to polymer reaction speed
