To select an infrared heating lamp suitable for a printing machine, you need to consider multiple factors. Here are some key points:
Power selection
Based on the production speed of the printing machine: A fast-producing printing machine needs to complete the drying or curing of the printing in a short time, so a high-power infrared heating lamp should be selected to provide enough heat to quickly remove moisture or cure the ink.
Consider the area and thickness of the printed pattern: Large-area, thick-coated printed patterns require more heat to dry or cure, and a higher-power heating lamp should be selected accordingly. If the printed pattern is small and thin, the power can be appropriately reduced to avoid excessive heating causing energy waste and possible adverse effects on the fabric.
Wavelength selection
Based on the characteristics of printing inks or coatings: Different inks or coatings have different requirements for the absorption wavelength of infrared. For example, water-based inks usually have a better absorption effect on infrared with a wavelength of 2.5-3.5 microns, while UV inks are more sensitive to infrared with a wavelength of 3.5-4.5 microns. Therefore, it is necessary to select an infrared heating lamp with a corresponding wavelength according to the specific ink or coating used by the printing machine to achieve the best drying or curing effect.
Combined with fabric material: Fabrics of different materials have different absorption and penetration capabilities for infrared rays. Generally speaking, cotton fabrics absorb infrared rays with a wavelength of 2.5-3 microns better, while polyester fabrics absorb infrared rays with a wavelength of 3-4 microns more strongly. Choosing a heating lamp with a wavelength that matches the fabric material can improve heating efficiency and ensure printing quality.
