× Large heat loss, energy utilization rate less than 10%; × Drying speed and quality heavily depend on the wind field; × Difficulty in achieving high-speed and thick coating processes. |
|
× High working temperature with potential for combustion and explosion; × Uneven infrared field, resulting in excessively dry, wrinkled, and cracked pole pieces; × Complex installation and high usage cost, requiring cooling systems. |
