Infrared heating lamps have important and extensive applications in printing machines. The following is a detailed introduction:
Drying effect
Principle: Infrared Heating Elements can emit infrared radiation. When this radiation is irradiated on the fabric just printed by the printing machine, the water and other solvent molecules in the fabric absorb the energy of infrared rays, produce violent vibrations, and then quickly heat up and evaporate to achieve a drying effect.
Advantages: Compared with traditional hot air drying and other methods, infrared heating drying is faster. For example, in some high-speed printing machines, the use of infrared heating lamps can shorten the drying time of printing from a few minutes to tens of seconds or even shorter, greatly improving the production efficiency of the printing machine.
Curing effect
Principle: For some processes that use special inks or coatings for printing, such as UV ink printing, halogen heating lamps can provide the required energy to cause the resin and other components in the ink or coating to undergo cross-linking reactions, thereby achieving curing. The cured printed pattern has better wear resistance, water resistance, and chemical resistance.
Advantages: infrared heating elements can achieve rapid curing and uniform curing effect. This helps to improve the quality and stability of printed patterns and reduce problems such as fading and falling off of patterns caused by incomplete curing. At the same time, rapid curing can also enable the printed fabric to enter the next process more quickly, further improving production efficiency.
