Halogen heating tubes can be used for ink drying. They have the advantages of high thermal efficiency, fast heating, and uniform radiation, which can effectively improve the efficiency and quality of ink drying:
– Radiative heat transfer: After the halogen heating tube is powered on, the tungsten wire heats up to generate infrared radiation. After the molecules in the ink absorb the energy of infrared radiation, the molecular movement intensifies and the internal energy increases, so that the solvent in the ink evaporates quickly and the ink is dried. This method of radiative heat transfer can directly act on the ink without the need to conduct heat through the medium, so the drying efficiency is high.
– Hot air convection assistance: When using halogen heating tubes for ink drying, hot air convection is usually accompanied. The halogen heating tube heats the surrounding air, causing the air temperature to rise, and the hot air flows upward to form convection. The convection of hot air can take away the solvent volatilized in the ink, further promoting the drying of the ink.
