红外线是一种热的辐射波,属于不可见光谱,它的穿透能力很强(能穿透云雾、织维、黑纸、玻璃、石英等),物料被红外线照射后辐射能即转化为热能,达到干燥的目的。近来红外线干燥法已广泛应用于化学、食品及其他工业部门,但在德造生产中应用还少。在铸造生产中用红外线干燥砂型可以获得很大的干燥强度,设备紧凑,使用灵活,既经济又卫生。水玻璃砂用红外线进行表面干燥可以大大节
Infrared is a kind of heat radiation wave, which belongs to the invisible spectrum. Its penetrating ability is strong (can penetrate clouds, weaving dimension, black paper, glass, quartz, etc.). After the material is irradiated by infrared ray, it is converted into heat energy , To achieve the purpose of drying. Recently infrared drying method has been widely used in chemical, food and other industrial sectors, but the German-made production is also less. In the casting of sand production with infrared drying can get a great drying strength, compact equipment, flexible use, both economical and hygienic. Water glass sand with infrared surface drying can be big festival
