How to prevent scratches on the protective film of aluminum composite panel

- Sep 02, 2020-

When the aluminum-plastic plate protective film is printed with scratches, the main thing is that the residual solvent is adhesion. We can solve it by slowing down the speed of the printing machine, increasing the amount of hot air, and adjusting the solvent formula. Adding a mixed solvent of ethanol, isopropanol, and xylene to the ink, and appropriately increasing the amount of isopropanol can increase the drying speed of the ink.

If the temperature rises in the production of aluminum-plastic plate protective film, the ink will also cause adhesion due to softening. Therefore, the temperature of the general printed matter should not exceed 40°C. If the tension is too large or the roll diameter is too large during winding, it will If the part is stressed, it will also cause adhesion. Therefore, do not lie horizontally when placing the protective film of the aluminum-plastic composite panel. It is better to place it vertically. After making the bag, lightly wrap it and place it in the carton vertically to reduce the surface The pressure between.

In normal production, if there is a problem in the printing of the aluminum-plastic panel protective film, causing scratches on the surface, it will affect the sales volume and affect the fit of the use, so we must learn and solve this problem. At the same time, it can improve the efficiency of the enterprise.
