生［、厚みが大きくなるに従って温度差も大きくなる。In other words, dielectric heating does not use conductive heating, but generally (1) heat generation occurs simultaneously at the center of the thickness of the backing material and at the outer 1m side (11, for example, 5 mm or more). In the backing material, the generated moisture escapes to the outside f
Due to the delay in temperature rise on the outer surface side, the internal heat is trapped due to the cooling effect from the outside, creating a temperature difference between the inside and the outer surface.[As the thickness increases, the temperature difference also increases.
