一、前言远红外烘烤技术已广泛用于食品、药材、木材、橡胶、纺织、茶叶、涂料等的加工和干燥之中。我们对一些国产的不同类型的油漆和同一类型不同颜色的油漆测定了它们的红外吸收光谱(见附图)。读者可以从特征峰位置和相对吸收率的大小,分析其烘烤的可能性及其最佳温度控制范围,以使能耗最低,时间最短,达到较好的经济效益。二、红外线吸收和烘烤许多实践已经证明,利用近红外线或可见光波段的电磁辐射烘烤物体,效果并不理想。因为有机高分子物质和饱含水分的物质,它们对红外线的吸收主要在3—25微米 I. Introduction Far-infrared baking technology has been widely used in food, medicine, wood, rubber, textile, tea, paint and other processing and drying. We measured their IR absorption spectra for some domestic different types of paints and different types of paints of the same type (see photo). From the characteristic peak position and the relative absorption rate, the reader can analyze the possibility of baking and the optimal temperature control range so that the lowest energy consumption and the shortest time can reach the better economic benefits. Second, the infrared absorption and baking Many practices have proved that the use of near-infrared or visible light band electromagnetic radiation baking objects, the effect is not satisfactory. Because of the organic polymers and water-rich substances, their absorption of infrared is mainly in the 3-25 micron
