Infrared heating tubes have important applications in printing machines. The following is a related introduction:
Working principle
Infrared heating tubes in printing machines mainly use the thermal effect of infrared rays to achieve drying and color fixation of printed fabrics. When current passes through the heating element in the heating tube, the heating element generates heat, which in turn stimulates infrared radiation. Infrared radiation radiates to the printed fabric and is absorbed by moisture and dyes in the fabric, intensifying molecular movement and generating heat, thereby achieving rapid drying and color fixation.
Advantages
Efficient and energy-saving: Infrared heating tubes can directly transfer energy to the heated object, with low heat loss. Compared with traditional hot air heating methods, it can effectively shorten the drying time, improve production efficiency, and reduce energy consumption.
Uniform drying: It can provide a relatively uniform heat distribution, so that the printed fabric is heated evenly during the drying process, avoiding printing quality problems caused by local overheating or overdrying, such as uneven color and pattern deformation, which helps to ensure the consistency and stability of printing.
Precise temperature control: With the corresponding temperature control system, the infrared heating tube can accurately control the heating temperature to ensure that the temperature is always kept within the appropriate range during the printing drying and color fixing process, which is conducive to improving the quality and fastness of the printing.
Environmental protection and cleaning: No harmful gases and pollutants are generated during the infrared heating process, which is environmentally friendly and will not cause secondary pollution to the printed fabric, meeting the requirements of modern industrial environmental protection production.
