Application of air knife in printing ink rapid drying system


Air Knife is a device that uses the principle of high-speed airflow to spray air onto the surface of the printed matter through a specially shaped nozzle. In printing ink rapid drying systems, air knives are often used to accelerate the evaporation and drying process of ink, thereby achieving faster print production cycles.

The main applications of air knives in printing ink rapid drying systems include the following points:

Rapid evaporation of solvents: Many printing inks contain volatile solvents. Using an air knife to blow high-speed airflow onto the surface of the printed matter can cause the solvent to evaporate faster and speed up the ink curing process.

Uniform drying: The air knife can produce uniform airflow to ensure that the ink is evenly dried on the entire printed surface, avoiding quality problems caused by uneven drying.

Prevent the accumulation of printed matter: In the printing ink rapid drying system, the high-speed airflow of the air knife can effectively blow the printed matter off the conveyor belt of the printing machine, preventing the printed matter from accumulating because the ink is not dry.

Energy saving and environmental protection: Using air knives for rapid drying can reduce the energy consumption of traditional hot air drying systems because there is no need to preheat a large amount of air. This helps reduce energy costs and is also more environmentally friendly.

In short, the air knife provides high-speed airflow in the printing ink rapid drying system to accelerate the volatilization and drying of the ink, thereby improving the printing production efficiency, reducing the production cycle, and ensuring the quality of the printed matter. However, the specific application methods and effects may be affected by the type of printing ink, differences in printing equipment, and actual operations.
