Abstract
Recently water mold washes are replacing alcoholic types to improve the working environment and ensure safety. A dryer is necessary for the water mold wash. In this research, far infrared rays was emitted from a radiation panel by using the heat emitted when LPG was oxidized with a platinum catalyst, and the possibility of drying the water mold wash using a far infrared rays dryer which also applies hot air emitted from the heat was examined.
Before using the far infrared rays dryer, the using conditions of this device were set. The contribution rate to dryness decreased in order of sheets of panel, distance, ventilation, and output.
Next, the relation of the far infrared rays dryer and the type of mold wash was clarified. It was found that the drying time differed according to the kind of mold wash and the absorption rate of far infrared rays according to the kind of mold wash. The drying efficiency was calculated from the emission rate of far infrared rays and absorption rate of each material. A high correlation was seen between the value and actual measurement value. This enable the selection of the suitable mold wash for the far infrared rays dryer.
