Improved heating device for imidization furnace

Technical Field

The utility model relates to an imination firing equipment technical field especially relates to an improved generation imination stove heating device.

Background

At present, PI film manufacturers in China almost use a thermal imidization method to produce polyimide films, because the thermal imidization method is simpler in technological process and equipment compared with a chemical imidization method. In the imidization link, the thermal imidization method is mainly used for heating up through a traditional resistance heater, convection heat conductivity is formed by heating air through the resistance heater, and the temperature in an imidization furnace is raised to about 400 ℃; the mode can generate very high temperature without rhythm of air flow, the space in the imidization furnace is continuously enlarged along with the continuous increase of the width of the film, the air in the imidization furnace flows very slowly, the large-capacity space reaches very high temperature through convection heat transfer, a long-time heating process is needed, the conduction efficiency is extremely low, the energy consumption is very high, and the method is not economical and time-consuming.

The other heating mode is far infrared heating, the far infrared heating has air convection and heat radiation, most of radiation heat transfer also reduces the influence on all areas generated by convection heat transfer, the film is heated up quickly, and the imidization efficiency is improved by 2-4 times. In the later application process, the far infrared lamp tube is fragile, the broken film covers the shielding lamp tube after the film is broken and is difficult to clean, and the heating mode of the resistance heater returns to the application again due to factors such as the error of the radiation on the actual measurement value of the temperature sensor. How to improve the heating efficiency of the resistance heater, reduce the heating time, and whether to improve by other means is a problem which needs to be solved urgently at present.
