Abstract

The invention discloses a curing furnace for curing hydrophilic aluminum foil, which comprises a furnace body, several curing channels and an exhaust system; the upper and lower parts of the curing channel are equipped with infrared medium-wave heating tubes, and the curing channel There is also a temperature sensor inside; the two ends of the infrared medium-wave heating tube are connecting terminals and non-connecting terminals respectively; the infrared medium-wave heating tube includes a first infrared medium-wave heating tube, and the first infrared medium-wave heating tube The tube includes a first lamp tube and a first helical filament arranged in the first lamp tube; the helical pitch of the first helical filament gradually decreases from the terminal to the non-connection end. The invention effectively reduces the temperature difference between the left and right PMT plates by adjusting the helical pitch of the filament of the infrared mid-wave heating tube in the curing furnace, improves the curing uniformity of the curing furnace, and makes the curing more uniform. By further optimizing the parameters of the curing furnace, the temperature difference between the left and right PMT plates of the hydrophilic aluminum foil can be kept within 8°C.

Description

technical field [0001] The invention relates to the technical field of hydrophilic aluminum foil, and more particularly relates to a curing furnace for curing hydrophilic aluminum foil. Background technique [0002] In the production process of hydrophilic aluminum foil, the coating needs to be cured by heating after coating. At present, the curing furnace used for curing hydrophilic aluminum foil is changed from the original vertical hot air curing to horizontal heating lamp radiation curing. Basically, infrared heating lamps are used for radiation heating. The characteristics of the curing furnace using infrared heating lamps The heating speed is fast and the heating is stable, but the disadvantage is that the heating uniformity is not as good as the vertical hot air curing, which will cause the temperature difference between the left and right PMT boards cured by the hydrophilic aluminum foil to be more than 20°C, and the difference in the temperature of the left and righ...
