The application of carbon fiber in printing drying has many advantages:
1. Efficient drying method:
– Matching absorption spectrum: Environmentally friendly water-soluble inks and water-based inks commonly used in printing contain a lot of water, which needs to be evaporated quickly to achieve drying and curing. The OH group vibration wavelength of water will have strong absorption bands in the 2.7-3 micron and 6-12 micron bands, and textiles used for printing also show strong absorption bands in the 2.5-15 micron band. The infrared wavelength of carbon fiber electric heating tube is 2.0-15 microns, which can well match the absorption spectrum of water-soluble inks, water-based inks and textiles. This allows the infrared emitted by the carbon fiber heating tube to be quickly absorbed by the water and fibers in the ink and textiles, thereby accelerating the volatilization rate of water and co-solvents and achieving efficient drying.
– Rapid heating and temperature uniformity: Carbon fiber materials have low thermal inertia and extremely fast heating speed. They can reach a high temperature in a short time after power-on, which can meet the requirements of rapid heating for printing drying. In addition, the carbon fiber heating element heats evenly, and the infrared radiation it generates can be evenly irradiated on the printing material, so that the material is evenly heated as a whole, avoiding the problem of incomplete drying or inconsistent drying effect caused by uneven local temperature, and improving the drying quality.
2. Energy-saving and environmental protection characteristics:
– Significant energy-saving effect: Carbon fiber is a highly efficient heating material, and the electric heat conversion efficiency can reach more than 95%. Compared with traditional heating methods, such as resistance wire heating and halogen lamp heating, it can more effectively convert electrical energy into thermal energy, reducing energy waste. In the long-term use of printing drying, it can save a lot of energy costs for enterprises.
– Environmental protection and pollution-free: No open flame will be generated during the heating process of carbon fiber, nor will it require the burning of fuel to produce exhaust gas like hot air heating, which will not pollute the printing material, and will not harm the working environment and the health of operators. In addition, the carbon fiber heating tube will not generate electromagnetic radiation during operation, which meets environmental protection requirements.
3. Convenient operation and stability:
– Easy to control: The carbon fiber heating tube heats up quickly, with short start-up and shutdown time. It only takes 3-5 seconds from zero power to full power output or from full power to zero power output, which is convenient for real-time temperature adjustment and control according to the process requirements of printing drying, and the operation is simple and convenient.
– Stable performance: In frequent startup, shutdown and long-term continuous work, the power of the carbon fiber heating tube is stable, and there will be no instantaneous power shock, which ensures the stability and reliability of the printing drying process. Its long service life reduces the maintenance and replacement frequency of the equipment and reduces the operating costs of the enterprise.
4. Strong equipment applicability:
– Applicable to a variety of printing processes: Whether it is traditional screen printing, transfer printing, or emerging digital printing processes, the carbon fiber heating device can be well adapted to them. For example, in digital printing, the carbon fiber heating tube can quickly dry the ink output by the digital printer to ensure the color vividness and firmness of the pattern.
– Customizable design: According to different printing equipment and drying requirements, carbon fiber heating tubes of different specifications, shapes and powers can be customized to meet the installation and use requirements of various printing drying equipment.
