Abstract

PURPOSE:To enable heating speed to be heightened without applying mechanical stress to high molecular material by a method in which the heating medium gasified by preheating is caused to be in contact with high molecular material and is condensed, and then it is heated by microwave induction heating. CONSTITUTION:A heating medium is heated by a heater 8 and becomes gaseous heating medium 7b, and then is blown to high molecular material 2 through a blowing nozzle 9 by way of a gas flowing device 11. Because the temperature of the high molecular material 2 adjacent to the inlet of a preheater 6 is low, when the gaseous heating medium 7b is in contact with the high molecular material 2, said medium 7b is condensed, and heightens the temperature of the high molecular material 2, giving its condensation heat to said material 2. The preheated high molecular material is moved to a microwave heater 12 at the state where the condensed heating medium 7c has adhered to its surface, and is heated to the temperature of heat treating operation. Simultaneously, the heating medium 7 adhering to its surface is removed by evaporation. Because the value (epsilonrtandelta) of the high molecular material 2 is sufficiently large by preheating, it is effectively heated in short time by microwave.

It had drawbacks such as a decrease in

Therefore, since the absorbed heat AQ is small in the low temperature region, there is a drawback that heating takes a long time.

The heating medium (7) is heated by the heater (8) and becomes a gaseous heating medium (7b), which is blown into the polymeric material (2) from the blowing nozzle (9) by the gas flow device aυ. In this case, the gaseous heat medium (7b) blown from the blowing nozzle (9) is directed towards the arrow (3) along which the polymeric material (2) runs.

り込まれる循環をくり返す。Since it is about twice as large, it can be heated uniformly in a short time. Further, the gaseous heating medium (7b) is made of a polymeric material (2
), the polymer material (2) is blown at a relative velocity of almost zero, so no harmful mechanical stress is applied to the polymer material (2) during the condensation process. That is, if similar condensation is performed while the gaseous heating medium (7b) is stationary, the polymeric material (2) is moved so that the condensed heating medium (7c) reaches the traveling speed of the polymeric material (2). ) receives power from
Conversely, a tensile force acts on the polymer material (2) due to the reaction force. For this reason, the molecular material (2) will be subjected to mechanical stresses other than those specified during the stretching or heat treatment process, resulting in significant quality deterioration or cutting. Then, the condensed heat medium (7c) is transferred to the roller (
4) When the running direction of the polymer material (2) changes, a part of it receives centrifugal force and moves into the preheater (6) as shown by the arrow.
), it is gasified again by the heater (8), and is sent to the blowing nozzle (9) again by the action of the gas pumping device kf (10) together with the uncondensed gaseous heating medium (7b). Repeat.

The heat that adheres to the surface as it is heated up to! I¥(7) is removed by evaporation. The evaporated heat medium (7) is recovered to the preheater (6) through the pipe α-men. In this case, since the polymer material (2) has a sufficiently large value (εr-δ) due to preheating, it can be efficiently heated in a short time by the microwaves. Then, the heat-treated polymer material (2) is heated to a specified temperature with a microwave heater (A) and then rolled into a take-up roll (

Since we were constrained to perform microwave dielectric heating afterward,
This has the effect that the heating rate can be improved without applying mechanical stress to the polymer material.
