(Summary description)Leather curing or drying with quartz infrared radiation has the following characteristics:
(1) The use of high efficient-infrared heaters to dry leather is relatively fast, much faster than the general use of steam hot air convection and heat conduction dryers to dry leather. Because the transmission of infrared radiation energy is direct, it can directly reach the surface of the leather without passing through any intermediate medium, and part of the radiation can penetrate into the interior of the leather pores, with a penetration depth of up to 0.1 mm~2.0mm. The radiation from the capillary pores is almost completely absorbed after a series of reflections by the pore walls, so the heat transfer efficiency is very high. For the same leather, drying with far-infrared radiation can greatly shorten the drying time.
(2) The drying quality is good. Since the surface layer of the leather and the inner layer below the surface absorb far-infrared radiation at the same time, the drying is relatively uniform. After drying, the physical properties of the leather are better and the color is improved.
(3) Compared with other radiation drying and other electric drying methods, quartz infrared radiation drying consumes less energy, more than 50% of the energy be saved. Furthermore, the infrared radiating element of the infrared dryer has a simple structure, small equipment size, and is easy and safe to operate.
Although high efficient-infrared drying has the above advantages, there are still two points that need to be paid attention to when drying:
(1) When infrared radiation is used to dry leather, the leather area shrinks greatly, 20% to 30% for grid leather and 4% to 6% for base leather. Therefore, it is best to dry in a constrained state (fixed state).
(2) Due to the infrared drying, the heat supplied to the leather and the water is much greater than when using the steam method, even dozens of times higher. The external heat source provides strong heat, and the temperature difference between the leather surface and the interior of the leather is large. Therefore, infrared radiation heater is most suitable for drying thin leather and drying the leather surface after painting.
