| titleOfInvention | Imidization device and imidization method for preparing polyimide fiber filaments |
| abstract | The invention relates to the field of polyimide preparation, and discloses an imidization device and an imidization method for preparing polyimide fiber filaments, wherein the device comprises a sealed cylinder body and a rotary multilayer oil pool-shaped filament coil placing frame arranged in the cylinder body; the rotary multilayer oil pool-shaped wire coil placing frame comprises a rotary supporting shaft vertically arranged in the cylinder body and a plurality of wire coil placing grooves sequentially fixed on the rotary supporting shaft in series; one end of the rotary supporting shaft penetrates through the top or the bottom of the cylinder body and is connected with a matched motor; the inner wall of the cylinder body is provided with a plurality of microwave emitters and infrared emitters corresponding to the positions of each layer of the silk roll placing grooves. The device can greatly improve the quantity of fiber imidization treatment in unit time, improve the production efficiency, greatly reduce the energy consumption and the production cost, prevent treated fiber strands from being bonded, and has small unwinding tension fluctuation, difficult end breakage and good service performance in the processes of processing after stretching and using. |
