远红外在工业上的应用是七十年代开始的。由于研究的逐步深入,技术水平的迅速提高,目前远红外的应用范围已扩展到国民经济的各个领域。远红外加热技术广泛地应用于工业及农业各部门,但在建筑方面应用于养护混凝土,则是近年来才开始的,目前尚处于试验研究阶 The application of far infrared in the industry began in the 1970s. Due to the gradual deepening of research and the rapid improvement of the technological level, the scope of application of far-infrared radiation has been extended to various fields of the national economy. Far-infrared heating technology is widely used in various industrial and agricultural sectors, but it has only recently begun to be applied in the construction of concrete for conservation. Currently, it is still in the experimental research stage.
