Why is it difficult to dry ink on the surface of aluminum foil? How to solve this problem?
reason:
① Because aluminum foil is a non absorbent material, the low viscosity phase of the binder or solvent in the ink can not penetrate into it, so the initial drying of the ink on it is affected.
② For the ink of oxidation conjunctiva, because its surface smoothness is too high, it is difficult for oxygen to enter from the side of the paper pile and react with the ink to solidify, which affects the drying.
③ Due to the structural differences between the two sides of the aluminum foil paper, the temperature of the ink should not be too high when it is dried on its surface, otherwise it will cause curling and even change the ink color, thus affecting the drying speed of the ink.
Solution: use fast drying ink; add appropriate amount of desiccant; use UV ink; use thick aluminum foil paper, when the drying temperature is high, can reduce the degree of deformation.
